The 5019400303 is a 3-position, single-row header from the Molex Pico-Clasp 501940 series, on a 1.00 mm pitch. It terminates by SMT and mates with the corresponding Pico-Clasp receptacle (e.g., Molex 501939 series) for board-to-cable/wire applications.
The 50 V voltage rating is adequate for low-voltage logic and power distribution.
Essential for board-to-cable connectivity; without correct mate, design fails.
Determines if connector can handle circuit load; critical for design validation.
Affects sourcing lead time and cost; buyers need immediate availability.
Pricing per volume impacts BOM cost and procurement decision.
Provides alternatives for supply chain flexibility and cost reduction.
Maintenance techs need fast replacement; urgent purchase.
