307-031-525-102

Edgeboard Connectors Overview

The EDAC Inc. model 307-031-525-102 is a standard card edge connector from the 307 series, designed for single-edge board applications. It features 31 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 5.08 mm. The connector accepts PCBs with a nominal thickness of 1.57 mm. It utilizes copper alloy contacts with gold plating to ensure reliable signal transmission. The housing is constructed from green thermoplastic material, providing electrical insulation rated at 5 GOhms. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified supply chain partners. Confirm RoHS compliance status and specific lot traceability requirements against project specifications. Ensure storage conditions maintain moisture sensitivity level integrity prior to soldering processes. Cross-reference ordering suffixes to confirm exact termination and plating variations match design intent.

Edgeboard Connectors Selection Notes

Select this component when a single-row card edge interface with 31 positions is required. Verify that the target printed circuit board thickness aligns with the 1.57 mm specification. Ensure the application environment remains within the -40°C to +105°C operational temperature range. Confirm that panel mounting constraints accommodate the vertical installation angle and physical dimensions of the header.

Edgeboard Connectors Part Context

This part belongs to the EDAC 307 Series, which provides standardized card edge connectors featuring 3.96 mm contact spacing. The series offers various position counts and termination options to support diverse electronic assembly needs. These headers are engineered for robust mechanical retention and consistent electrical performance in demanding industrial environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models such as 307-016-559-204 or 307-040-522-203, provided position counts and termination types match the original design requirements. Any replacement must maintain identical pitch, board thickness compatibility, and mounting style to ensure mechanical fit and electrical continuity without redesigning the host PCB.
