306-036-421-102

Overview

The EDAC Inc. 306-036-421-102 is a standard card edge connector receptacle featuring 72 positions with a 3.96 mm (0.156 inch) pitch. Designed for dual-edge card insertion, it utilizes tin-plated copper alloy contacts rated for 5 A current. The component supports printed circuit boards with a nominal thickness of 1.57 mm and employs a vertical panel mount installation style. Its insulator body is constructed from thermoplastic material, providing a low-profile configuration suitable for space-constrained electronic assemblies requiring reliable signal transmission.

Feature Summary

• Dual-edge female connector design accommodating two-sided card edges
• Low-profile insulator body construction for compact assembly integration
• Vertical panel mount orientation ensuring stable board retention
• Tin-plated contact surfaces for corrosion resistance and conductivity

Applications

• Industrial control system interface modules
• Telecommunications equipment backplanes
• Test and measurement instrument card slots
• Computer peripheral expansion interfaces

Procurement Notes

Verify the specific plating finish against official datasheets, as distributor listings may indicate tin or gold variants for similar part numbers. Confirm that the 72-position count aligns with the required dual-edge card specifications. Ensure the 3.96 mm pitch matches the target PCB trace layout. Cross-reference the panel mount requirements with the mechanical drawing to verify hole patterns and mounting hardware compatibility before finalizing procurement orders.

Selection Notes

Select this component when a high-density connection with a 3.96 mm pitch is required for dual-edge cards. It is appropriate for applications needing a robust vertical panel mount solution with a low-profile footprint. Consider the 5 A current rating and tin plating for general-purpose industrial environments. Ensure the selected variant matches the exact contact plating specification required by the application's environmental conditions.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and pitch options for diverse electronic interconnection needs. The 306-036-421-102 specifically addresses high-density requirements with its 72-position configuration. It complements other EDAC connectors by providing standardized dimensions and reliable performance for modular electronic systems.

Replacement Considerations

Direct substitutes within the EDAC 306 series include parts with identical pitch and position counts but different plating or housing colors. Verify mechanical compatibility and electrical ratings before swapping. Generic replacements must match the 3.96 mm pitch and 1.57 mm board thickness constraints to ensure proper fit and function.
