PCB Connector Market Size & Share 2026-2035

PCB Connector Market Size

The global PCB connector market was valued at USD 18.3 billion in 2025 and is projected to reach USD 19.4 billion in 2026 and USD 35.2 billion by 2035, expanding at a CAGR of approximately 6.8% from 2026 to 2035.

PCB connectors provide electrical and mechanical interfaces between circuit boards, cables, wire harnesses, and external devices. Demand is being reshaped by the increasing electronics content of electric vehicles, denser 5G radio networks, AI-oriented data center equipment, and miniaturized consumer devices. Electric car sales exceeded 17 million units in 2024, while the International Energy Agency expects sales to surpass 20 million units in 2025, increasing the installed base of vehicles requiring battery-management, inverter, charging, sensing, and in-cabin electronic systems . The ITU reports that 5G accounted for 36% of active mobile-broadband subscriptions globally in 2025, creating continuing demand for RF, board-to-board, and backplane interconnects in radio and network equipment . ^{[1]International Energy Agency, Global EV Outlook 2025: Trends in Electric Car Markets. iea.org}

Asia Pacific generated USD 7,258.3 million in 2025, representing approximately 39.6% of global revenue. Its lead reflects the concentration of electronics manufacturing, consumer-device assembly, EV production, and 5G infrastructure across China, Japan, South Korea, and India. North America accounted for USD 5,702.7 million, or approximately 31.1%, supported by AI data center deployment, defense electronics, and automotive demand. Europe represented USD 4,029.9 million, or approximately 22.0%, with automotive electronics and industrial automation providing its principal demand base.

Board-to-Board connectors were the largest connector type in 2025, with USD 4,459.8 million in revenue and approximately 24.3% share. Power connectors are projected to post the fastest connector-type growth, at approximately 8.71% CAGR through 2035, while Automotive & Transportation is the fastest-growing application at approximately 8.88%. SMT is the largest mounting technique, accounting for approximately 35.9% of revenue in 2025, and is projected to grow at approximately 7.90% CAGR.

The market is therefore less dependent on a single electronics cycle than on several equipment transitions occurring simultaneously. Asia Pacific benefits from manufacturing scale and domestic end-market demand, whereas North America is positioned to capture a larger share of high-specification data center and defense-related demand. Suppliers able to qualify products for automotive temperature, vibration, voltage, and high-speed transmission requirements are likely to gain more from this shift than suppliers competing primarily on commodity connector volume.

Key Drivers

Vehicle electrification is increasing connector content per platform

EV architectures require PCB-level connections across battery-management systems, traction inverters, DC/DC converters, on-board chargers, displays, cameras, radar, and other sensing hardware. This increases both connector count and the value of qualified interconnects relative to internal-combustion vehicle architectures. Global electric-car sales rose by more than 25% in 2024, and China accounted for more than 11 million sales, reinforcing the scale of the automotive electronics opportunity .

Hirose's FH79 automotive FPC connector illustrates how automotive electrification and ADAS reshape product specifications. The 0.3 mm-pitch product was developed for solid-state LiDAR, electronic mirrors, and vehicle displays and provides an approximately 40% width reduction versus conventional 0.5 mm-pitch alternatives . Its AU1 automotive wire-to-board connector supports USB 3.2 Gen2, DisplayPort 1.4, and HDMI transmission and is designed to comply with USCAR-2 and USCAR-30 requirements . These requirements raise engineering and validation barriers, favoring suppliers that can provide both miniaturization and automotive-grade reliability. ^{[3]Hirose Electric, Hirose Electric Introduces FH79 Series 0.3 mm Pitch FPC Connector for Automotive Applications. hirose.com}

5G densification supports high-frequency and high-density interfaces

Mobile broadband traffic reached an estimated 1.5 zettabytes in 2025, with traffic growing at an average annual rate of 19% since 2021 . The resulting network load requires additional radio capacity, edge processing, and transport equipment. In 5G radio hardware, RF and board-to-board connectors must preserve impedance control and limit insertion loss, crosstalk, and electromagnetic interference as operating frequencies rise.

Millimeter-wave antenna-in-package designs are particularly demanding because interconnect performance affects both signal transmission and antenna integration. IEEE packaging research identifies low-loss, high-bandwidth interconnects and high-density PCB structures as central design considerations for 5G+ applications . This supports the projected expansion of the RF connector segment from USD 2,464.5 million in 2025 to USD 5,032.0 million by 2035. ^{[4]IEEE Electronics Packaging Society, State-of-the-Art Packaging, Interconnects and AiP Modules for Millimeter-Wave 5G+ Applications. eps.ieee.org}

Device miniaturization rewards density without compromising EMI performance

Wearables, smartphones, laptops, gaming devices, and AR/VR equipment require greater functional density in limited board area. Molex's Quad-Row Shield Board-to-Board connector combines a four-row signal layout with an integrated metal shield, providing up to 25 dB of EMI reduction compared with non-shielded alternatives while reducing size by approximately 30% relative to dual-row designs . More than 50 million units had shipped from the platform since its 2020 launch .

The commercial value of miniaturization is not limited to smaller connector footprints. Higher pin density can increase crosstalk and EMI exposure, particularly where multiple radios, displays, cameras, and processors operate in close proximity. Suppliers that integrate shielding and maintain signal quality can reduce the number of separate mitigation components required in a device, supporting adoption in space-constrained electronics.

AI data centers are raising high-speed and power-delivery requirements

AI servers and high-capacity network switches require more power and shorter, cleaner signal paths than conventional enterprise compute systems. Molex launched its Impress Co-Packaged Copper Solutions in February 2026 for near-ASIC connectivity at data rates up to 224 Gbps PAM-4, with development extending toward 336G and 448G applications . The design addresses the performance constraints that emerge as network architectures move toward 3.2T systems.

Financial results from major connector suppliers show that this demand is already material. Amphenol's Communications Solutions segment increased 29% to USD 6,324 million in 2024 and reached USD 12,056 million in 2025, aided by AI-related IT datacom demand and acquisitions . TE Connectivity reported 24.6% year-on-year growth in its Communications Solutions segment in the fourth quarter of fiscal 2024, citing AI-related data connectivity as a key contributor . These trends support power connectors' projected 8.71% CAGR as GPU racks and network equipment require higher-current distribution systems.

Industrial connectivity is moving toward Ethernet-based control architectures

Automation, robotics, and rail modernization are expanding the role of connectors in machine control, motion feedback, and distributed communications. HARTING introduced the Han Protect, D-Sub PushPull, and Single Pair Ethernet product lines in 2025. Its Single Pair Ethernet solution was validated for North American Class 1 freight railroads and supports 10 Mbps transmission over distances up to 1,000 m while reducing cable weight relative to traditional Ethernet arrangements .

PCB production indicators also point to a stronger electronics manufacturing environment. IPC reported that North American PCB shipments increased 11.3% year-on-year and bookings rose approximately 18% in February 2025, taking the book-to-bill ratio to 1.33 . For connector suppliers, this improves the near-term demand environment for industrial controls, transportation equipment, and related electronic assemblies.

Key Restraints

High-speed interfaces require increasingly specialized signal-integrity engineering

At high data rates, connector geometry, grounding, via design, dielectric material, and trace length can materially affect insertion loss, impedance discontinuity, differential-pair skew, and eye margin. These problems become more acute in 5G millimeter-wave systems and AI networking hardware, where IEEE research identifies low-loss interconnect design as a critical packaging challenge .

The move to 224 Gbps PAM-4 illustrates the constraint. Molex's near-ASIC product architecture reduces the electrical path between processing and network elements because conventional board-level signal paths can become difficult to sustain at the highest data rates . This raises development costs for connector suppliers and can accelerate the use of optical interconnects where copper performance is insufficient. The restraint does not eliminate demand; it redirects value toward suppliers with electromagnetic simulation capability, advanced materials expertise, and close customer engineering support.

Thermal cycling and compact power systems lengthen qualification cycles

Connector reliability can deteriorate when temperature changes affect contact force, contact resistance, housing properties, and PCB-interface geometry. Automotive power electronics are particularly demanding because components must tolerate vibration, humidity, thermal cycling, and high-voltage operation. Hirose's automotive high-voltage connector range is rated to 1,000V AC/DC and designed for operating temperatures from -40°C to +125°C, demonstrating the qualification standard required for EV battery, inverter, and DC/DC converter applications .

High-power computing equipment presents a related challenge. As rack and card power density increases, connector suppliers must validate mechanical stability and contact performance under elevated operating temperatures. Press-fit designs can be especially sensitive to dimensional control because their reliability depends on the interference fit between the connector and PCB. These constraints lengthen design-in and approval timelines, particularly in automotive, aerospace, medical, and high-performance computing applications.

That creates a sharper divide between standard interconnect supply and performance-critical connector programs. Suppliers capable of validating high-speed, high-voltage, and automotive-grade products can convert engineering complexity into longer design cycles, stronger customer integration, and higher switching costs. Suppliers unable to support those requirements may remain exposed to lower-value volume applications even as overall PCB connector revenue expands.
