The 2-2106751-4: It terminates 22 AWG wire directly into the insulation displacement slot — no crimping, no separate terminal.
Pitch and Footprint — What Fits Where
That means the PCB footprint needs 4.00 mm between adjacent through-hole pins. The 4-position count is the BOM line match — if your circuit count is 4, this is the one.
Wire Gauge — Stick to 22 AWG
The feed-through feature means the wire passes straight through the connector body.
Active lifecycle, ROHS3 compliant.
