306-023-421-103

Overview

The EDAC Inc. 306-023-421-103 is a dual female card edge connector designed for panel mount and through-hole termination. It features 46 positions arranged in two rows with a 0.156-inch (3.96mm) pitch. The connector utilizes copper alloy contacts with tin plating and polyester thermoplastic insulation. It supports board thicknesses ranging from 0.054 to 0.070 inches and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual female contact configuration for secure card edge mating
• Flush mount flange design with floating bobbin feature
• Tin-plated copper alloy contacts for reliable signal transmission
• Polyester thermoplastic insulation material for thermal stability

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pin count, plating type, and mounting style compatibility. Confirm that the target printed circuit board thickness falls within the specified acceptance range of 0.054 to 0.070 inches to guarantee proper mechanical retention and electrical contact integrity during assembly and operation.

Selection Notes

Select this component when a dual-row female connector with a 3.96mm pitch is required for panel-mounted applications. Ensure the design accommodates the flush mount flange dimensions and verify that the tin-plated contact finish meets the environmental corrosion resistance requirements of the intended operating environment compared to gold-plated alternatives.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various row counts, pitch options, and mounting configurations to support diverse high-density interconnection needs. The 306-023 variant specifically addresses applications requiring 46 positions with robust mechanical locking capabilities for vertical board insertion.

Replacement Considerations

Cross-reference with EDAC 306-043-421-104 for higher position counts or EDAC 306-023-421-112 for alternative flange features. Verify that any substitute maintains the same 0.156-inch pitch and dual female gender to ensure mechanical and electrical compatibility with existing card edge designs.
