SL Series 15-Circuit Single-Row Crimp Housing
The Molex 50-57-9215 is a 15-circuit, single-row crimp housing from the SL (Stackable Linear) interconnect family. Its description — SL CRP HSG C SR FRNT RBS 15CKT — tells you it's a housing with front polarization ribs, which prevents mis-mating with the wrong header. This is the receptacle side of a wire-to-board connection; it accepts SL-series crimp terminals terminated to discrete wires, then locks into a mating SL header. The front ribs key the housing so only a header with matching slots will engage, a simple but effective safeguard on a harness assembly line.
The RoHS3 compliance covers the full substance restriction list (including the four phthalates), which matters for EU-market equipment and any BOM that requires full RoHS exemption traceability. No lead-free process concerns here — the housing material itself is the compliance driver.
The front ribs mean the housing is polarized — it only mates one way, so the harness builder needs to orient the terminal insertion correctly during crimping. No secondary terminal position assurance (TPA) on this housing; the primary latch in the housing cavity retains the terminal.
No stock-holding claim; the supply posture is per-request procurement. The Box package (bulk) is standard for housings of this size — no tape-and-reel, just loose parts in a bag or box.
