2.0mm Pin Header — 2.0mm Pitch Male PCB Connector, Single & Double Row
2.0mm Pin Header — Compact 2.0mm Pitch Male PCB Connectors for Embedded Systems & Sensor Modules
The 2.0mm pitch pin header bridges the gap between the ultra-fine 1.27mm debug headers and the ubiquitous 2.54mm (0.1") standard. At 2.0mm pitch, these headers offer higher current capacity than 1.27mm (rated 3A per contact at 1000V max) while maintaining a compact footprint suitable for dense PCB layouts, compact sensor modules, industrial control boards, and embedded system interconnects. They are widely used in consumer electronics, automotive interior modules, and precision measurement equipment.

2.0mm Pin Header Buying Guide
Step 1 — Confirm pitch: 2.0mm pitch is distinct from both 1.27mm and 2.54mm. Measure center-to-center pin spacing on your existing connector before ordering. A 2.0mm header will not mate with 2.54mm or 1.27mm sockets.
Step 2 — Row configuration: Single-row headers are used for simple signal and power connections. Double-row headers provide higher pin density for multi-signal interfaces. Confirm your PCB footprint matches the row count.
Step 3 — Mounting style: Straight DIP headers are soldered through the PCB vertically. Right-angle SMT headers are reflow-soldered horizontally on the board surface. U-shape (button-entry) headers allow cable insertion from the side, useful for panel-mount designs.
Step 4 — Current requirements: At 3A per contact and 1000V rating, 2.0mm headers are suitable for moderate-power applications. For high-current power connections (≥5A), consider 2.54mm or larger pitch headers with heavier wire gauges.

Frequently Asked Questions
Q: Is 2.0mm pitch the same as 2.54mm (0.1") pitch?
A: No. 2.0mm and 2.54mm are different pitches and are not interchangeable. 2.0mm headers require 2.0mm mating sockets. Always verify pitch before ordering.
Q: What current can 2.0mm pin headers handle?
A: 3A per contact at up to 1000V. For multi-pin connectors, the total current is limited by the wire gauge and PCB trace width, not just the contact rating.
Q: Can I cut the 1×40P breakaway header to a custom length?
A: Yes. Use flush-cut wire cutters to snap or cut the header at any pin position. The remaining pins are fully functional after cutting.
Q: What female header mates with 2.0mm pin headers?
A: Our 2.0mm Female Header collection provides the matching socket connectors. Ensure pitch (2.0mm) and row count match your pin header.
Q: Are 2.0mm pin headers compatible with JST PH2.0mm connectors?
A: No. JST PH2.0mm connectors use a different housing system (crimp terminals in a plastic housing) and are not directly interchangeable with PCB pin headers, even though both use a 2.0mm pitch. Pin headers require matching female socket headers, not JST PH housings.
