306-036-421-158

Overview

The EDAC Inc. 306-036-421-158 is a dual-edge female card edge connector from the 306 series, featuring 72 positions with a 0.156-inch (3.96mm) contact spacing. It utilizes cantilever contacts with gold plating and is designed for panel or through-hole installation. The unit supports PCB thicknesses of 0.054 to 0.070 inches and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual-edge female configuration with cantilever contact type
• Gold-plated contacts for reliable signal transmission
• Flush mount flange with top opening and threaded inserts

Applications

• Industrial control systems
• Communication equipment backplanes
• Medical device interconnects

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required PCB thickness and mounting style. Confirm RoHS3 compliance status as per current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a high-density dual-edge interface is required with robust mechanical retention. Ensure the host PCB design accommodates the specified 0.156-inch pitch and that the enclosure allows for flush mounting with 4-40 threaded insert access.

Part Context

This part belongs to the EDAC 306 series, which provides standard card edge connectors with 0.156-inch spacing. The series is widely used in general-purpose electronic applications requiring durable, solder-tail connections for double-sided edge boards.

Replacement Considerations

Direct substitutes include EDAC 306-036-421-107, which shares identical electrical and mechanical specifications but differs in lead-free status verification. Cross-reference with other 306-series variants only if pin count and spacing match exactly.
