306-021-421-108

Edgeboard Connectors Overview

The EDAC Inc. 306-021-421-108 is a standard card edge connector receptacle from the 306 series. It features 42 positions with a 0.156-inch (3.96 mm) pitch and supports dual-sided card edges. The connector utilizes gold-plated copper alloy contacts for reliable signal transmission and employs a solder pin termination method. Designed for panel mount installation, it accommodates board thicknesses ranging from 0.054 to 0.070 inches. The housing is constructed from thermoplastic polyester, ensuring durability in demanding environments.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 42-position count and 3.96 mm pitch before ordering. Confirm that the target printed circuit board utilizes a double-sided card edge design compatible with this dual-receptacle format. Ensure the mounting environment supports the specified panel mount style and that the operating temperature range aligns with application requirements.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with 42 positions is required within a standard 3.96 mm grid. The gold plating is suitable for applications requiring low contact resistance and long-term reliability without frequent mating cycles. Consider the panel mount constraint and verify that the enclosure design allows for the necessary vertical clearance and access for card insertion.

Edgeboard Connectors Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and termination options to support diverse interconnect needs. The 306-021-421-108 specifically addresses applications requiring a moderate density interface with robust mechanical retention and standardized dimensional tolerances for compatibility with industry-standard card edge profiles.

Edgeboard Connectors Replacement Considerations

Consult official EDAC documentation for direct cross-reference data. Verify that any substitute maintains the identical 42-position count, 3.96 mm pitch, and dual-side receptacle geometry. Ensure material specifications, particularly contact plating and insulation type, meet or exceed original performance criteria.
