The 2159320470: This is a 4-position, single-row header on 2.50 mm pitch — the same pitch used across the Mini-Lock 215932 family. The 0.098" spacing sets the PCB land pattern and the receptacle it mates with: any Mini-Lock 2.50 mm crimp housing with 4 cavities will fit. If it doesn't click, it's not mated.
Surface-mount termination and board retention
Termination is solder — this is an SMT right-angle header.
Rated temperature and flammability
The housing is glass-filled nylon (PA) rated UL94 V-0 — the highest flame-retardant grade for connectors inside equipment enclosures.
Current rating and wire gauge
In the Mini-Lock system, the mating receptacle accepts 20–24 AWG wire; the actual current limit should be read from the terminal datasheet at the target wire size and ambient temperature.
