The 5054331271 is a 12-position, dual-row header on 1.25 mm pitch, surface-mount, from the Molex Micro-Lock PLUS 505433 series. It mates with the matching Micro-Lock PLUS receptacle housing (sold separately) for a board-to-cable/wire connection.
Mated stacking height is 8.6 mm, set by the header insulation height of 0.285" (7.25 mm) plus the receptacle height.
Design engineers need pin mapping to ensure correct circuit routing.
Sourcing buyers need immediate availability to avoid production delays.
Buyers compare cost across distributors for BOM pricing.
Maintenance techs and brokers need lifecycle status to plan replacements or avoid EOL.
Ensures compatibility for board-to-cable assembly.
Design engineers and buyers need alternatives if primary source is unavailable.
