305-018-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-018-556-204 is a standard card edge connector from the 305 series, designed for panel-mounted vertical installation. It features an 18-position dual-row configuration with a 3.96 mm pitch. The connector supports PCB thicknesses of 1.57 mm and utilizes gold-plated copper alloy contacts for reliable signal transmission. Rated for 5 A current, it employs solder lug termination for secure board attachment. The housing is constructed from thermoplastic material, ensuring stability within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact termination style and contact plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the 18-position layout aligns with the mechanical constraints of the intended panel mount enclosure. Cross-reference the RoHS compliance status with current regulatory requirements for the destination market.

Edgeboard Connectors Selection Notes

Select this component when a 3.96 mm pitch dual-row connector is required for vertical panel mounting. The 18-position count suits moderate-density interconnect needs. Verify that the 5 A current rating meets the circuit load requirements. Ensure the application environment falls within the specified -40°C to +105°C operational temperature range for optimal performance and longevity.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options for diverse electronic assembly needs. The 305-018-556-204 specifically addresses applications requiring a 18-position dual-row configuration with solder lug termination. It complements other variants in the family that differ in row count, pitch, or mounting style.

Edgeboard Connectors Replacement Considerations

Consult EDAC technical support for direct substitutes within the 305 series. Verify that any alternative maintains the 3.96 mm pitch and 18-position count. Ensure mechanical dimensions and termination types match the existing PCB footprint and panel cutout specifications.
