Its 4.20mm pitch and latch lock fastening make it a common choice for power distribution in computer, automotive, and industrial harnesses where a positive mechanical lock is needed to prevent accidental disconnect under vibration.
This receptacle mates with any Mini-Fit Jr 5557-series header of the same 4.20mm pitch and 12-circuit count — typically a Molex 43045-series vertical or right-angle header.
The description clearly states contacts are not included, so buyers must order terminals separately.
Buyers need to know the corresponding male header to complete the connector system.
Pitch compatibility is critical for PCB layout and ensuring proper mating with headers.
RoHS compliance is often a regulatory requirement for electronic products.
Sourcing buyers need to quickly identify authorized distributors with stock.
While the housing itself doesn't carry current, buyers often inquire about system current capacity to ensure suitability.
