305-030-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-030-555-503 is a dual-edge female card edge connector from the 305 Series. It features 30 positions with a 0.156" (3.96mm) contact spacing and 0.140" (3.56mm) row spacing. Designed for non-specified dual-edge cards, it accepts PCBs with a nominal thickness of 0.062" (1.57mm). The connector utilizes gold-plated copper alloy contacts housed in a green thermoplastic insulator body. It supports a continuous current rating of 5A and withstands 1800VACrms dielectric voltage.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body design for compact assembly requirements
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard double-sided PCBs
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify that the target application utilizes non-specified dual-edge PCBs compatible with the 0.156" pitch. Confirm that the board thickness aligns with the 0.062" nominal specification to ensure proper mechanical retention. Ensure the design accommodates the required 5A current rating and 1800VACrms insulation capability for the intended electrical environment.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, dual-edge female connector is required for 30-position circuits. It is suitable for applications needing polarizing key compatibility to prevent misalignment during insertion. Choose this part over single-row variants when both sides of the PCB require connection points within the specified dimensional constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series of standard card edge connectors. The series is characterized by its versatility in accepting various polarizing keys and its consistent 0.156" pitch across multiple position counts. The 305-030-555-503 specifically addresses the need for a 30-position interface with dual-edge access capabilities.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-030-500-503, which shares identical electrical and mechanical specifications but may differ in specific packaging or minor manufacturing revisions. Cross-series replacements require verification of pitch, row spacing, and PCB thickness compatibility.
