306-022-525-104

Overview

The EDAC Inc. 306-022-525-104 is a standard card edge connector from the 306 Series, designed for dual-edge board applications. It features 44 positions with a 3.96 mm (0.156 inch) pitch and utilizes copper alloy contacts with gold plating. The unit supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. Constructed with a thermoplastic insulator, it accommodates PCB thicknesses typically between 1.30 mm and 1.80 mm. This vertical receptacle provides reliable interconnection for expansion cards in industrial environments.

Feature Summary

• Dual-edge female configuration for secure expansion card mounting
• Gold-plated copper alloy contacts ensure low contact resistance
• Thermoplastic housing provides thermal stability up to 105°C
• Vertical panel or through-hole mounting style options

Applications

• Industrial control system expansion modules
• Telecommunications equipment interface boards
• Test and measurement instrument backplanes
• Automotive electronic control unit connections

Procurement Notes

Verify the specific pin count and row configuration against the official datasheet before procurement, as series variations exist. Confirm that the target PCB thickness falls within the specified mechanical tolerance range. Ensure the operating environment temperature does not exceed the rated maximum limit of 105°C. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a high-density dual-edge connection is required for rigid circuit boards. The 3.96 mm pitch offers robust spacing for high-current applications compared to finer pitches. Consider the vertical orientation for space-constrained panel installations. Verify compatibility with mating card edge thicknesses to ensure proper retention force and electrical continuity during vibration.

Part Context

This connector belongs to the EDAC 306 Series, which specializes in heavy-duty card edge solutions. The series is characterized by its durable thermoplastic construction and high current carrying capacity. It serves as a critical interconnect solution in sectors requiring reliable mechanical retention and stable electrical performance under harsh conditions.

Replacement Considerations

Direct substitutes within the same series include models like 306-022-525-102 or 306-022-525-107, provided the position count and pitch match exactly. Alternative manufacturers may offer similar specifications, but mechanical footprint verification is mandatory. Always validate insulation resistance and termination type compatibility before substitution.
