The 77311-102-31LF: All positions are loaded, no option for depopulation.
Operates from -65°C to 125°C — wide enough for outdoor telecom cabinets, industrial enclosures, and unheated storage. The UL94 V-0 housing means it won't sustain a flame inside equipment that requires a flammability rating.
The connector carries a UL94 V-0 flammability rating on the thermoplastic housing — confirm specific RoHS/REACH status and any applicable UL file number against the manufacturer's current declaration.
