Listed for automotive, general-purpose, medical, and telecommunications equipment — the UL94 V-0 housing and gold-plated contacts support these environments. The unshrouded style is common for board-to-board or cable-to-board connections where the mating housing provides the keying and alignment.
Design engineers need to validate dimensions and electrical specs for fit.
Sourcing buyers require pricing for BOM costing and budgeting.
Immediate production or repair needs depend on real-time availability.
Supply chain flexibility and alternative sourcing depend on cross references.
Production planning requires lead time estimates to avoid delays.
Completing the connection in design requires the correct female counterpart.
