306-021-421-101

Overview

The EDAC Inc. 306-021-421-101 is a standard card edge connector receptacle designed for panel mount applications. It features a dual female configuration with 42 positions arranged in a single centerline row. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with copper alloy contacts featuring tin plating, the unit employs a thermoplastic polyester insulator body. It supports solder pin termination and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Accepts PCBs with a nominal thickness of 1.57 mm
• Features low profile insulator body construction
• Utilizes tin-plated copper alloy contacts for reliable termination

Applications

• Panel-mounted electronic assemblies requiring board-to-board connectivity
• Industrial control systems utilizing standard thickness PCBs
• General-purpose interconnect solutions for edgeboard applications

Procurement Notes

Verify that the target printed circuit board thickness aligns with the specified 1.57 mm nominal requirement to ensure proper mechanical engagement. Confirm that the application environment remains within the -40°C to +105°C operating temperature range. Ensure compatibility with the 3.96 mm pitch and single-row configuration during design integration. Check for RoHS compliance status if required by specific regulatory standards.

Selection Notes

Select this component when a single-row, dual female connector is required for panels mounting. The 3.96 mm spacing accommodates standard board layouts while the 1.57 mm thickness acceptance fits common PCB specifications. Tin plating offers cost-effective conductivity suitable for general environments. Consider alternative series if higher current ratings or different board thicknesses are necessary.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series provides various position counts and spacing options for diverse interconnect needs. The 306-021-421-101 specifically addresses applications needing 42 positions with a 3.96 mm pitch. It represents a standard solution for vertical panel mounting scenarios.

Replacement Considerations

Direct substitutes within the same series include parts sharing the 306-021 base number but differing in contact count or termination style. Verify exact dimensional compatibility before swapping. No other cross-series replacements are confirmed without detailed engineering review.
