302-070-656-201

Edgeboard Connectors Overview

The EDAC Inc. part number 302-070-656-201 is a standard card edge connector from the 302 Series, designed for dual-edge board applications. It features 70 positions with a contact spacing of 0.050 inches (1.27 mm). The connector utilizes female contacts made of copper alloy with gold plating and employs a cantilever contact type. It is intended for through-hole solder termination and supports PCB thicknesses ranging from 0.051 to 0.071 inches (1.30 mm to 1.80 mm). The housing is constructed from black polyamide (PA66) nylon 6/6 material.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with 70 female positions for secure board insertion
• Gold-plated cantilever contacts ensure reliable electrical connectivity
• Through-hole solder termination for robust mechanical attachment
• Polyamide insulation housing rated for -55°C to 85°C operating temperatures

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Consumer electronics motherboards
• Medical device circuit boards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count and contact spacing. Ensure compatibility with the target PCB thickness range of 1.30 mm to 1.80 mm. Confirm RoHS compliance status if required by project specifications. Cross-reference the package quantity details with authorized distributors to align with assembly line requirements.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-edge connector is required for space-constrained designs. The 1.27 mm pitch allows for dense routing compared to larger pitch alternatives. Verify that the mating card edge thickness falls within the specified tolerance. Consider the black color coding if visual identification of the connector series is necessary for assembly processes.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 302 Series, which specializes in low-profile card edge solutions. The series is characterized by its fine 0.050-inch pitch and durable gold-plated contacts. It is widely used in applications demanding reliable signal transmission in compact form factors. The manufacturer provides CAD models and dimensional drawings to assist in PCB layout integration.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 302-036-656-201 and 302-012-256-201, differing primarily in position count. Ensure any replacement maintains the 1.27 mm pitch and dual-edge configuration. Verify that the mounting style and termination method remain compatible with the existing PCB design.
