306-036-420-101

Overview

The EDAC Inc. 306-036-420-101 is a standard card edge connector designed for dual-edge board insertion. It features 72 positions arranged in a single row with a 0.156-inch (3.96mm) pitch. The connector utilizes cantilever spring contacts made of copper alloy, plated with tin for reliable signal transmission. Insulation is constructed from green polyester thermoplastic, providing structural integrity and electrical isolation. Rated for operation between -40°C and 105°C, it supports vertical through-hole termination via solder pins.

Feature Summary

• Dual-edge female connector design accommodates double-sided circuit boards
• Cantilever spring contact mechanism ensures secure mating engagement
• Tin-plated copper alloy contacts provide durable conductive pathways
• Green polyester thermoplastic insulation offers thermal stability

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Consumer electronics module assembly

Procurement Notes

Verify the specific contact plating configuration against project requirements, as datasheets may list variations such as gold or tin finishes for this series. Confirm that the 0.156-inch pitch aligns with the target PCB trace spacing to prevent manufacturing defects. Ensure the operating temperature range meets the environmental conditions of the final application before procurement.

Selection Notes

Select this component when a single-row, dual-edge interface is required for moderate-density connections. The 72-position count suits applications needing balanced I/O distribution without excessive board width. Verify compatibility with the target board thickness and ensure the through-hole mounting style fits the assembly constraints.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its versatility in handling various board thicknesses and its robust mechanical design. The 306-036-420-101 specifically represents a high-pin-count variant within this family, optimized for applications requiring extensive signal routing in a compact form factor.

Replacement Considerations

Cross-reference compatible parts within the EDAC 306 series that share the same 0.156-inch pitch and 72-position count. Ensure substitute components match the cantilever contact type and through-hole termination method to maintain mechanical and electrical continuity.
