Board fit and routing for a 4-position right-angle header
The 5-103635-3: This is a 4-position, single-row header from the AMPMODU MTE series, pitched at 0.100" (2.54 mm) — the standard grid for breadboard and prototype layouts. Each male pin is square brass with 15.0 µinch gold over nickel on the mating surface — enough plating for repeated connect-disconnect cycles in field-service or test-fixture roles. The 4-wall shrouded housing with a latch holder protects the pins from accidental stubbing and locks the mating receptacle in place — useful in automotive or industrial harnesses where vibration could back out an unlatched connector.
