306-036-521-112

Overview

The EDAC Inc. 306-036-521-112 is a dual female card edge connector designed for high-reliability applications. It features 72 positions arranged in two rows with a 0.156-inch (3.96 mm) pitch. The contacts are constructed from copper alloy and gold-plated to ensure stable electrical performance. The housing utilizes Diallyl Phthalate (DAP) material, providing thermal stability within an operating temperature range of -40°C to +125°C. This component supports straddle mount installation via PC pins, offering robust mechanical retention for circuit board interfaces.

Feature Summary

• Dual female contact configuration for secure card edge mating
• Gold-plated copper alloy contacts for reliable conductivity
• DAP housing material ensures thermal resistance up to 125°C
• Straddle mount design provides enhanced mechanical stability

Applications

• High-reliability industrial control systems
• Aerospace and defense electronic modules
• Military communication equipment interfaces
• Automotive electronics requiring thermal stability

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, plating thickness, and mounting style. Ensure compatibility with the target PCB stack-up and mating card thickness specifications before procurement. Cross-reference the part number with authorized distributors to confirm current availability and lead times, as supply chain fluctuations may impact delivery schedules for this specialized connector series.

Selection Notes

Select this connector when a dual-row interface with a 0.156-inch pitch is required for high-temperature environments. The DAP housing material makes it suitable for applications exceeding standard plastic limits. Verify that the straddle mount footprint aligns with the PCB layout constraints. Consider the 72-position capacity for signal density requirements and ensure the gold plating meets the necessary cycle life expectations for the intended application.

Part Context

This component belongs to the EDAC 306 series of edgeboard connectors, which are engineered for demanding environments. The series typically offers various position counts and mounting options. The 306-036-521-112 specifically addresses needs for dual-sided connectivity with high thermal endurance. It serves as a critical interconnect solution in sectors where vibration resistance and long-term reliability are paramount, distinguishing it from standard commercial-grade connectors.

Replacement Considerations

Direct substitutes must match the 72-position count, 0.156-inch pitch, and dual female configuration. Verify that alternative parts support straddle mount installation and utilize DAP or equivalent high-temperature housing materials. Ensure the replacement maintains compatible contact plating and current ratings. Consult the manufacturer's cross-reference guide for officially validated equivalents to guarantee mechanical and electrical interoperability.
