The 640445-5: A shrouded 1-wall design means the header has a partial wall on one side to guide the mating receptacle, reducing the chance of misalignment during assembly.
Tin-Plated Contacts — Mating Cycles and Current Handling
Tin contacts are rated for fewer mating cycles than gold — typically 25 to 50 cycles — but deliver reliable performance in environments without corrosive gases or frequent reconnection. For a 5-position header in a harness, the limiting factor is often the wire's current-carrying capacity, not the contact itself.
The header terminates via through-hole solder — the 0.125" (3.18mm) post length is designed for standard 1.6mm PCBs. The natural color housing is glass-filled thermoplastic, providing dimensional stability during wave soldering.
It is RoHS compliant and available for order through independent distribution channels.
