SL-Series Single-Row Housing, 14 Circuits
The Molex 50-57-9514 is a 14-circuit, single-row crimp housing from the SL (Stackable Linear) series. The part description — SL CRP HSG H SR 14CKT OPT H — indicates it is a housing (HSG), single-row (SR), with the option for an integral polarizing key (OPT H) that prevents mis-mating with non-keyed headers.
Compliance and Regulatory Status
The 50-57-9514 carries a ROHS3 Compliant rating, meeting the strictest EU RoHS exemption criteria including the four phthalates. This is a hard gate for equipment destined for European markets or for BOMs requiring full substance compliance.
This housing accepts SL-series crimp terminals (such as the 70058 or 70021 series) for 22-28 AWG wire. It mates with SL-series pin headers, including both vertical and right-angle configurations, in the same 14-circuit single-row layout. The optional polarizing key (OPT H) aligns with a corresponding slot in the mating header to prevent incorrect insertion.
