Right-angle header with a latch that holds
The 5-104361-3: This is a 4-position, single-row, right-angle header from the AMPMODU MTE series, on 0.100" (2.54mm) pitch. Rated 3A per contact with a -65°C to 105°C operating range, it's specced for Automotive, General Purpose, Medical, and Telecommunications applications.
Mating contacts are gold-plated at 15.0µin (0.38µm) — that's the standard AMPMODU MTE gold flash, good for repeated mating cycles in field-serviceable gear. The post tails are tin-plated at 100.0µin (2.54µm), which solders cleanly to the through-hole board.
