The Molex 0022012101 is a 10-circuit receptacle housing from the KK254 (2695) series.
Sizing the BOM Line — What You Need Alongside It
Contacts Not Included is the headline sourcing note. The 10-position count is the fit check: confirm your circuit count before committing.
Crimp termination — you need the matching Molex crimp tool to seat the terminal into the housing. Free-hanging (in-line) mount means this housing sits in the harness, not on a PCB. It mates with the standard KK254 header (0.100" pitch, single row). The white nylon body is keyed by the housing geometry — no mix-up with a different row count. ROHS3 compliant.
