305-022-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-022-555-203 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 22 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating, it supports a current rating of 5 A. The insulator body is made of thermoplastic polyester, providing an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female configuration for non-specified dual-edge card insertion
• Low profile insulator body design for compact panel mounting
• Gold-plated copper alloy contacts ensuring reliable signal transmission
• Thermoplastic polyester housing offering thermal stability

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control module interfaces
• Telecommunications equipment backplanes
• Test and measurement instrument cards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm mechanical dimensions and contact type. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the dual-edge requirement matches the system design. Check RoHS compliance status if environmental regulations apply to the end product.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, vertical mount solution is required for 1.57 mm thick boards. The 3.96 mm pitch suits applications needing higher density than standard .100 inch headers but lower than fine-pitch connectors. Verify that the 5 A current rating meets the electrical load requirements of the connected circuitry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-022 variant specifically provides 22 contacts in a dual-row arrangement. It is distinct from single-row or different pitch variants within the same family.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC 305-022-520-203 and 305-022-556-568, provided they match the required pin count and mounting style. Cross-reference mechanical drawings to ensure panel cutout compatibility.
