For a given wire size, the contact temperature rise stays within the housing's UL94 V-0 polyester limit.
The through-hole right-angle mounting requires a PCB with plated holes on a 0.100" grid. The contact length - post is 0.130" (3.30 mm), which determines the solder tail length below the board — sufficient for standard 0.062" thick PCBs with a typical solder fillet.
ROHS3 compliant — no lead, mercury, cadmium, or other restricted substances above threshold limits.
The 2-644488-4 mates with MTA-100 series IDC or crimp receptacles (female housings) that accept 0.100" pitch ribbon cable or discrete wires. Confirm the receptacle's position count matches 4 positions.
Yes, the 2-644488-4 is ROHS3 compliant — it meets the EU RoHS directive for restricted substances. The housing material is UL94 V-0 rated.
