The 4-103765-0-21: The 0.230" (5.84 mm) mating pin length engages with standard IDC or crimp-socket housings of the same series. As a breakaway header, the 21-position strip is one segment of a longer pin carrier — the factory snaps it to length.
Right-Angle Through-Hole — Board-Edge Routing and Z-Height
The 0.090" (2.29 mm) post length is designed for standard 0.062" to 0.093" thick boards with through-hole soldering. The push-pull fastening keeps insertion and extraction simple in low-vibration environments.
Gold Mating Contacts — 30 µinch for Moderate-Duty Cycling
The post (solder tail) is tin-lead plated at 100 µinch (2.54 µm), which is a lead-bearing finish. Verify RoHS compliance requirements for your assembly process — the part is not marked RoHS in the spec record.
The base product number is 103765, which covers the AMPMODU Mod II breakaway header family. No direct pin-compatible equivalent from another manufacturer is documented — the footprint and mating half are specific to the TE Mod II system.
