What is the 6450543-6?
It uses press-fit termination through a through-hole PCB, eliminating the need for soldering — a common choice in high-reliability, solderless build processes.
Press-Fit Termination and Board Fit
Press-fit means the compliant pin deforms into the plated through-hole during insertion, creating a gas-tight joint without solder. This is the go-to termination for backplane and high-reliability assemblies where rework or field replacement matters — no heat damage, no flux residue. The through-hole mounting style requires a specific PCB hole diameter and board thickness; the 3-position layout with a guide pin assists alignment during press-in. Verify the board footprint against the product drawing before committing the layout.
The connector style is Multi-Beam, and the 3-power layout means all three positions carry power — no signal contacts here.
