Board-fit and sourcing posture
The 103673-3 is a 4-position single-row header from the AMPMODU MTE series, pitched at 0.100" (2.54 mm). The mating contacts carry a gold finish at 15.0 µin thickness, rated for 3 A per circuit. Gold over brass suits repeated mating cycles and environments where corrosion resistance matters — medical, telecom, or general-purpose industrial instrumentation.
Housing and retention features
A full 4-wall shroud protects the pins from stubbing during blind mating. A board lock and keying slot are built into the insulator.
RoHS status and compliance note
The 103673-3 is listed as RoHS non-compliant.
