305-056-500-203

Edgeboard Connectors Overview

The EDAC Inc. 305-056-500-203 is a standard card edge connector from the 305 series, designed for dual-edge female applications. It features 56 positions with a 3.96 mm (0.156 inch) pitch and supports two rows of contacts. The connector accepts PCBs with a thickness of 1.57 mm and utilizes gold-plated copper alloy contacts for reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms dielectric voltage, it employs a solder lug termination type. The housing is constructed from green thermoplastic polyester, ensuring compliance with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-row configuration supporting non-specified dual-edge cards
• Gold-plated copper alloy contacts for enhanced conductivity
• Accepts between-contact and in-contact polarizing keys
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment board connections
• Test and measurement instrumentation interfaces
• Automotive electronics module mounting

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact plating and termination style. Confirm panel cutout dimensions align with the flange specifications to ensure proper fit. Check for RoHS3 compliance documentation if environmental regulations apply. Ensure the receiving PCB thickness falls within the accepted range of 1.57 mm to prevent mechanical stress or poor contact. Validate that polarizing key requirements are met by the system design.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-edge interface is necessary. The 3.96 mm pitch allows for broader trace spacing compared to finer pitches. Consider the 5 A current rating for power distribution needs. Verify that the vertical panel mount style fits the enclosure constraints. Ensure the 1800 VACrms rating meets the insulation requirements of the application environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for robust construction. The series offers various position counts and mounting options. The 305-056-500-203 specifically addresses applications needing 56 contacts. It shares common design principles with other 305 series parts but differs in pin count and specific termination details.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 56-position count, 3.96 mm pitch, and dual-edge female configuration. Verify identical current ratings and voltage withstand capabilities. Ensure the replacement part supports the same polarizing key acceptance. Cross-reference flange dimensions for panel compatibility.
