The Molex 0901420024 is a 24-position dual-row receptacle from the C-Grid III 90142 series, built for wire-to-board and wire-to-wire harness applications where a positive lock and a wide operating temperature range matter.
The 24 circuits at 0.100" pitch match a 2x12 header footprint — count your BOM positions against that number before ordering. The locking ramp is the primary retention: it clicks into the mating header's latch pocket and keeps the pair mated on a machine or vehicle harness where cable strain is real. The -55°C to 105°C range means the housing and contact retention stay within spec from cold storage to a hot engine bay, but the current rating depends entirely on the crimp terminal you choose — this housing itself carries no current rating because the contacts are ordered separately.
Mating and Termination
This receptacle mates with C-Grid III 0.100" pitch pin headers — the locking ramp engages the header's latch feature for a vibration-resistant connection. Termination is crimp-style: you insert the female terminal into the housing cavity after crimping to the wire, and the locking ramp holds the assembly together. The housing is free-hanging (in-line), so it sits in the harness without a board mount — typical for a cable-to-board or cable-to-cable interconnect where the receptacle is the wire-side half.
