8 positions at 0.250-inch pitch — the board footprint decision
The 640584-3: This is an 8-position, single-row header on a 0.250-inch (6.35 mm) pitch — the spacing sets the minimum PCB real estate for the solder pads and the clearance between adjacent traces. The locking ramp fastening type audibly clicks when mated with a standard Universal MATE-N-LOK receptacle, providing vibration-resistant retention — useful in equipment that sees transport or fan vibration.
12 A per circuit with 30 µinch gold — power and cycle life
Each contact is rated 12 A at 600 VAC — the current ceiling is set by the contact cross-section and the UL94 V-0 nylon housing's thermal limits.
Mates with Universal MATE-N-LOK receptacle housings
Confirm the receptacle's circuit count and keying match the header's single-row, 8-position layout before committing to the BOM.
