Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm contact type, termination style, and flange options. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm RoHS compliance status if required by project specifications. Cross-reference the part number with the manufacturer's latest datasheet to validate availability and lead times before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when a robust card edge solution with polarizing key acceptance is required. The 3.96 mm pitch suits applications needing wider spacing for higher voltage isolation. The 5 A rating supports moderate power distribution needs. Consider the vertical or panel mount styles available within the 305 series family based on mechanical constraints. Verify that the mating card edge thickness falls within the specified operational limits.
