306-035-420-158

Overview

The EDAC Inc. 306-035-420-158 is a card edge connector designed for single-sided PCB applications. It features 70 positions arranged in two rows of 35 contacts each, with a 0.156-inch (3.96mm) pitch. The connector utilizes female, straight terminals with solder termination and locking capabilities. Constructed with a green thermoplastic insulator and copper alloy contacts finished with gold plating, it supports board thicknesses typically around 0.062 inches. The unit operates within a temperature range of -40°C to 105°C and is RoHS3 compliant.

Feature Summary

• Single centerline row configuration accepting nominal 0.062 inch PCB thickness
• Low profile insulator body design for space-constrained assemblies
• Integrated locking mechanism ensures secure connection stability
• Gold-plated copper alloy contacts provide reliable signal transmission

Applications

• Industrial control system interface connections
• Telecommunications equipment backplane interfaces
• Consumer electronics internal module interconnects
• Automotive electronic control unit connections

Procurement Notes

Verify the specific datasheet version for the 306 series to confirm exact mechanical dimensions and mating force requirements. Ensure the target printed circuit board thickness aligns with the connector's acceptance range. Confirm that the soldering process parameters are compatible with the gold contact finish and the specified operating temperature range to maintain long-term reliability.

Selection Notes

Select this component when a single-row, high-density connection is required for standard thickness boards. The 0.156-inch pitch offers robust spacing compared to finer pitches. Consider the locking feature if vibration resistance is critical. Compare against the 306-035-421-158 variant if a different pinout or mounting style is needed. Verify environmental ratings match the deployment conditions.

Part Context

This part belongs to the EDAC 306 series of card edge connectors, which are characterized by their single-row architecture and low-profile design. The series is engineered for general-purpose electronic applications requiring reliable board-to-board or board-to-backplane connectivity. The 306 series distinguishes itself through its specific 0.156-inch pitch and integrated locking features, catering to industries needing stable connections in compact form factors.

Replacement Considerations

The 306-035-421-158 is a documented equivalent within the same series. Verify mechanical compatibility before substitution. No other direct substitutes are confirmed in public documentation.
