2.0mm Female Header — 2.0mm Pitch PCB Socket Connector, Single & Double Row
2.0mm Female Header — Precision 2.0mm Pitch PCB Socket Connectors for Embedded & Industrial Applications
The 2.0mm pitch female header (socket connector) is the mating counterpart to 2.0mm pin headers, providing secure, reliable board-to-board and wire-to-board connections in compact embedded systems, industrial sensor modules, consumer electronics, and precision instrumentation. With gold-plated contacts and UL94V-0 flame-retardant insulators, these female headers deliver consistent electrical performance across thousands of mating cycles — essential for connectors that are frequently engaged and disengaged during assembly, testing, and field maintenance.

- Panel-mount connectors using U-shape (button-entry) variants
- Test fixture sockets for PCB functional testing and programming
- Automotive and consumer electronics subboard interconnects
2.0mm Female Header Buying Guide
Step 1 — Match to your pin header: 2.0mm female headers mate with 2.0mm pin headers only. Verify pitch, row count, and pin count before ordering. A 2.0mm socket will not fit a 2.54mm or 1.27mm pin header.
Step 2 — Entry direction: Standard straight female headers accept pins from above (vertical entry). U-shape (button-entry) headers accept pins from the side, useful for panel-mount or right-angle mating. Right-angle DIP headers exit horizontally from the PCB.
Step 3 — IC socket vs standard socket: Round-hole IC socket-style female headers use machined round contacts for repeated insertion of component leads (e.g., socketed ICs, test probes). Standard female headers use stamped contacts optimized for mating with square-post pin headers.
Step 4 — Breakaway cutting: 1×40P breakaway female headers can be cut to any length. Use flush cutters and score between pins for a clean break.

Frequently Asked Questions
Q: What is the difference between a standard female header and an IC socket-style female header?
A: Standard female headers use stamped spring contacts designed to mate with square-post pin headers. IC socket-style (round-hole) female headers use machined round contacts that accept both square pins and round leads (e.g., component legs, test probes), offering lower contact resistance and longer service life for high-cycle applications.
Q: Can 2.0mm female headers be used with JST PH2.0mm connectors?
A: No. JST PH2.0mm uses a proprietary crimp-terminal housing system and is not compatible with PCB pin header sockets, even though both use a 2.0mm pitch. They are different connector systems requiring different mating parts.
Q: What is the U-shape (button-entry) female header used for?
A: U-shape headers allow the mating pin header to be inserted from the side rather than from above. This is useful for panel-mount applications, right-angle board connections, or designs where vertical clearance is limited.
Q: Are these headers compatible with 2.0mm ribbon cable IDC connectors?
A: Our DC3-style IDC box headers (available in this collection) are designed for 2.0mm pitch ribbon cable termination and are compatible with standard 2.0mm IDC ribbon cables.
