The 5-103639-1 is a 2-position, single-row header from the AMPMODU MTE series by TE Connectivity. It mates with AMPMODU MTE receptacle housings (crimp or IDC) to form a wire-to-board or board-to-board connection. Full 4-wall shrouding protects the square male pins from bending during mating, and the latch holder provides a positive lock — the latch clicks when fully seated, resisting accidental disconnect in vibration-prone environments like automotive or industrial equipment. Rated 3 A per contact with tin-on-tin mating surfaces (100 µinch tin on both pin and post). Tin is cost-effective for low-cycle applications; expect 50–100 mating cycles before contact wear becomes a concern. For higher cycle life, consider the gold-plated variants in the same series.
Mating and termination checklist
This header mates with AMPMODU MTE receptacle housings (e.g., 5-103635 series for crimp terminals, or 5-103637 for IDC). The latch holder on the header engages the latch on the receptacle for a secure connection. Termination is through-hole solder. The contact length — post is 0.130" (3.30 mm), mating length is 0.230" (5.84 mm), overall 0.545" (13.84 mm) — fits standard 1.6 mm PCBs with room for solder fillet. Insulation height of 0.535" (13.60 mm) leaves clearance for adjacent components. The keying slot prevents mismating with non-keyed receptacles — confirm your mating half has the corresponding keyway.
