Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 357 Ordering Guide to confirm exact pin count, plating, and flange specifications. Ensure compatibility with target PCB thickness ranges before procurement. Confirm RoHS compliance status via the latest datasheet documentation. Cross-reference distributor part numbers with EDAC Inc. original identifiers to prevent substitution errors.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count vertical interface is required. The 3.96 mm pitch accommodates standard board layouts. Verify that the application environment stays within the -40°C to 105°C operating range. Consider the dual female design for mating with male card edges. Ensure mechanical clearance allows for the specified flange dimensions during assembly.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 357 series, which provides standard card edge solutions for various industries. The series offers multiple position counts and termination options. The 357-040 variant specifically addresses higher density needs compared to lower-position counterparts in the same family line.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 357 Ordering Guide for direct substitutes with identical electrical and mechanical parameters. Verify equivalent pitch and position counts when evaluating alternative part numbers.
