306-036-521-168

Overview

The EDAC Inc. 306-036-521-168 is a dual female card edge connector from the 306 series, designed for panel and through-hole mounting. It features 72 positions arranged in two rows with a 0.156-inch (3.96mm) pitch. The contacts are made of copper alloy with a gold finish, utilizing a cantilever contact type. The insulator is green thermoplastic polyester, supporting card thicknesses between 0.054 and 0.070 inches. Operating temperature ranges from -40°C to 105°C.

Feature Summary

• Dual row configuration with 72 total positions for high-density interconnect applications
• Cantilever contact design ensures reliable engagement with specified card edge profiles
• Thermoplastic polyester insulator provides structural integrity and environmental resistance
• Gold-plated copper alloy terminals offer corrosion resistance and stable electrical performance

Applications

• Industrial control system backplanes
• Telecommunications equipment interfaces
• Test and measurement instrument modules
• Automotive electronic control units

Procurement Notes

Verify that the specific part number matches the required 72-position dual female configuration before procurement. Confirm compatibility with the target PCB layout regarding panel mount flange dimensions and hole spacing. Ensure the selected variant meets the necessary RoHS compliance standards for the intended market. Cross-reference the operating temperature range against the application environment requirements to guarantee long-term reliability under thermal stress conditions.

Selection Notes

Select this component when a high-pin-count dual-row interface is required for rigid board connections. The 0.156-inch pitch accommodates standard board widths while maintaining signal integrity. Consider the cantilever contact style for ease of insertion and removal during maintenance. Evaluate the flush mounting feature against available chassis space constraints to ensure proper mechanical fit within the assembly enclosure.

Part Context

This connector belongs to the EDAC 306 series, which focuses on robust card edge solutions for demanding environments. The series utilizes standardized dimensions to facilitate integration into various industrial and commercial systems. The specific model represents a high-density option within the lineup, offering extensive connectivity options for complex circuit designs requiring secure mechanical and electrical attachment points.

Replacement Considerations

Compatible substitutes include the 306-036-521-102 and 306-037-521-168 models from the same manufacturer series. Verify pin count and pitch alignment when considering alternative part numbers to maintain mechanical and electrical compatibility.
