The 0430451218 is a Molex Micro-Fit 3.0 43045 series board-to-cable/wire header, surface-mount, with 12 positions loaded across 2 rows at 3.00 mm pitch.
The mating contacts are tin-plated, 60.0 µinch (1.52 µm) thick, on brass alloy pins.
It is ROHS3 compliant.
Buyers need the datasheet to validate electrical and mechanical specifications before design-in or replacement.
Immediate purchasing is the primary goal for sourcing buyers; knowing authorized distributors saves time.
Pricing impacts BOM cost and sourcing decisions; buyers compare across distributors.
Design engineers and technicians need the matching receptacle or housing to ensure full interconnect compatibility.
Stock availability directly affects lead time and production schedule, critical for urgent builds.
Pinout is essential for wiring and circuit design; incorrect mapping can cause board failures.
