306-021-421-102

Overview

The EDAC Inc. 306-021-421-102 is a standard card edge connector receptacle designed for panel mount applications. It features 42 positions with a 3.96 mm pitch and accepts printed circuit boards with a nominal thickness of 1.57 mm. The connector utilizes copper alloy contacts with tin plating, rated for 5 A current. Constructed with a thermoplastic polyester insulator, it operates within a temperature range of -40°C to +105°C. This vertical, single-row component ensures reliable electrical connections in industrial environments.

Feature Summary

• Accepts dual-edge PCBs with nominal 1.57 mm thickness
• Features low-profile insulator body for compact integration
• Provides secure panel mounting with vertical orientation

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Procurement Notes

Verify the specific contact plating configuration against project requirements, as datasheet variations may exist between tin and gold finishes. Confirm that the 1.57 mm board thickness tolerance aligns with the target PCB manufacturing specifications. Ensure the vertical panel mount style matches the enclosure design constraints before finalizing procurement orders.

Selection Notes

Select this model when a 42-position interface is required for 1.57 mm thick dual-edge cards. The 3.96 mm pitch suits applications needing robust mechanical stability. Consider the operating temperature range and current rating to ensure compatibility with the system's thermal and electrical loads during design phase evaluations.

Part Context

This component belongs to the EDAC 306 Series, which offers various position counts and termination options. The series provides standardized dimensions for easy replacement and integration into existing chassis designs. It serves as a reliable solution for connecting edgeboard modules to main systems in demanding operational settings.

Replacement Considerations

Compatible substitutes include the 306-021-421-112 variant, which differs primarily in contact plating material. Verify dimensional compatibility and pinout alignment when considering alternative part numbers from the same manufacturer series.
