Sizing the contact to the wire
The TE Connectivity 770985-1 is a stamped pin contact belonging to the Mini-Universal MATE-N-LOK series, a widely used TE family for wire-to-wire and wire-to-board power and signal interconnects. This contact accepts 22-26 AWG wire, which is the primary selection parameter — the crimp barrel must match the conductor diameter for a reliable gas-tight connection. The tin-plated brass construction suits moderate environments with limited mating cycles; for higher cycle counts or corrosive atmospheres, a gold-plated variant from the same series would be the better choice.
Mating half and housing compatibility
As a pin contact, the 770985-1 mates with the corresponding socket contact in the Mini-Universal MATE-N-LOK series. It inserts into the standard Mini-Universal MATE-N-LOK plug and receptacle housings — the same housings used across the series. The crimp termination requires the correct TE application tooling for the 22-26 AWG wire range; the contact is loaded into the housing after crimping, and the housing's integral locking lance retains it.
