The 0430451018: The 3.00 mm mating pitch and 3.00 mm row spacing set the board footprint — a direct fit for the matching Micro-Fit 3.0 receptacle housing. Shrouded on all four walls with a locking ramp fastening type: mates with the receptacle and locks audibly. Board-to-cable/wire style: the header solders to the PCB, the receptacle crimps onto the wire. Rated 600 V, temperature range -40°C to 105°C, UL94 V-0 housing.
SMT termination with solder retention
Tin-plated mating contacts at 60.0 µinch thickness — rated for moderate mating cycles. In a field-service application cycled quarterly, the contact interface holds up well past a decade of service. Brass alloy contact material.
No official successor or cross-reference from Molex; the 043045 base number covers the series.
Where it goes — automotive, industrial, medical, telecom
Applications listed include Automotive, General Purpose, Industrial, Medical, and Telecommunications. The locking ramp and 105°C rating suit under-hood and cabinet environments where connectors see thermal cycling and vibration.
