Headers, Male Pins Procurement Notes

Verify the specific suffix 'LC' against official Samtec documentation to confirm lead-compliant or low-cost variations if applicable, as standard datasheets may list generic TOLC variants. Ensure the part number matches the exact pin count and row configuration required for your PCB layout. Cross-reference with authorized distributors to confirm availability and authenticity, as supply chain statuses can change. Request sample units for mechanical fit verification before full-scale production deployment.

Headers, Male Pins Selection Notes

Select this component when a four-row, 1.27 mm pitch header is required for space-constrained applications. The vertical SMT form factor suits boards needing direct stacking or edge mounting. Consider the 2.4 A current rating and -55°C to +125°C operating range for environmental compatibility. Verify mating connector compatibility with Tiger Buy or similar systems to ensure proper engagement and signal integrity.
