306-025-420-102

Overview

The EDAC Inc. 306-025-420-102 is a standard card edge connector from the 306 series, designed for panel mount vertical installation. It features a dual female configuration with 50 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and accepts board thicknesses within the specified range. Contacts are constructed from copper alloy with tin plating to ensure reliable signal transmission. The housing is made of green thermoplastic polyester, providing insulation resistance of 5 GOhms. It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Dual female contact configuration for secure mating with double-sided card edges
• Vertical panel mount design for stable structural integration
• Tin-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester housing for electrical insulation

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Computing hardware peripheral interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm contact plating type and housing color. Ensure the target PCB thickness aligns with the connector's mechanical acceptance range. Confirm that the required current rating of 5 A meets the application's electrical load requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a high-density 50-position interface is required for vertical panel mounting. The 3.96 mm pitch offers robust spacing for higher voltage applications compared to finer pitches. Choose the tin-plated variant for general-purpose environments where gold plating is not strictly necessary. Ensure the dual-edge design matches the PCB manufacturing capabilities for double-sided conductive traces.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series provides various position counts and configurations for diverse connectivity needs. The 306 series is characterized by its durable thermoplastic construction and standardized dimensions, facilitating compatibility across multiple industrial and commercial electronic systems requiring reliable edge-board connections.

Replacement Considerations

Direct substitutes must match the 50-position count, 3.96 mm pitch, and dual female configuration. Verify that alternative parts support the same vertical panel mount style and thermal operating range. Cross-reference contact material and plating specifications to ensure equivalent electrical performance and durability under similar environmental conditions.
