Single-Pin Breakaway — Board-to-Board or Cable
It serves as a single-point interconnect for board-to-board or cable applications where only one circuit is needed.
Tin-Lead Finish — Legacy Plating, High Cycle Life
Tin-lead is not RoHS-compliant; this part is intended for exempt or non-RoHS applications. Compare to gold-plated AMPMODU Mod II headers: the tin-lead here costs less per position but is not rated for the same number of mating cycles in corrosive environments.
The base product number is 103759; the full 4-103759-0-01 suffix specifies the single-position, right-angle, tin-lead variant.
Through-hole, right-angle mounting — the 0.090" (2.29 mm) post length is designed for standard PCB thickness (0.062" to 0.093"). The solder tail is tin-lead plated; use a SnPb or compatible solder process. Unshrouded, push-pull retention means the pin is held by the solder joint alone — no locking latch. In high-vibration environments, consider a secondary mechanical anchor or a shrouded header. The black housing provides visual polarity reference.
