Plating and what it means for the application
The 0430451011: The hybrid gold/tin finish is the key spec here. The gold flash on the mating interface (30.0 µin nominal) supports the cycle life needed for field-removable or panel-I/O connections where re-mating is occasional. The 100.0 µin tin post finish handles reflow profiling without the wetting issues thin gold can introduce, and it is compatible with standard lead-free solder processes.
Fastening and shrouding for field service
The locking ramp on this header provides audible and tactile confirmation at full mate — useful in the field when you are verifying a harness seat without tooling. The four-wall shroud keeps the header centered in its receptacle under vibration, which is the usual failure mode in automotive and industrial panels where the connector backs out over time. The solder retention feature on the posts helps hold the part in the PCB paste during reflow assembly; it does not add mechanical retention after soldering, so for high-vibration board-level applications the through-hole variant (same series, different mounting type) is the better fit.
Sourcing posture
Listed Active with ROHS3 Compliant status — no stated last-time-buy or obsolescence notice in this record. The 043045 base product number is the series anchor; the 10-position count is mid-range in this family, so if the BOM position count shifts, a higher or lower position-count sibling in the same series is the direct cross-reference. Quoted to order against BOM quantity; confirm lead times for production volume runs.
Compliance snapshot
UL94 V-0 flammability rating on the LCP housing satisfies typical industrial and automotive material requirements. ROHS3 compliant covers EU end-of-life directives. The insulation height of 0.290 inch (7.37 mm) provides adequate creepage; verify board keep-out against your enclosure depth for dense panel builds.
