306-036-421-104

Overview

The EDAC Inc. 306-036-421-104 is a dual-edge card edge connector designed for panel mount and through-hole termination. It features 72 positions with a 0.156-inch (3.96mm) spacing across two rows of 36 contacts each. The connector utilizes copper alloy cantilever spring contacts with tin plating, rated for non-specified double-sided cards. It accommodates PCB thicknesses between 0.054 and 0.070 inches (1.37 to 1.78mm). The insulator is made of green thermoplastic polyester, supporting an operating temperature range from -40°C to +105°C.

Feature Summary

• Dual-edge receptacle design accepting non-specified double-sided circuit boards
• Cantilever spring contact mechanism ensures reliable electrical connection
• Thermoplastic polyester insulator body provides thermal stability
• Through-hole mounting style with flange for secure panel installation

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to ensure correct pin count and termination type. Confirm that the target printed circuit board thickness falls within the specified acceptance range of 0.054 to 0.070 inches. Check RoHS3 compliance status if environmental regulations apply to the final assembly. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability.

Selection Notes

Select this component when a dual-edge interface with 0.156-inch spacing is required for high-reliability applications. The tin-plated cantilever contacts offer cost-effective performance for general-purpose connections. Consider the through-hole mounting requirement and panel-mount flange dimensions during mechanical design. Verify that the operating temperature range meets the environmental conditions of the intended deployment scenario.

Part Context

This part belongs to the EDAC 306 Series, a line of standard card edge connectors. The series offers various position counts and termination options. The 306-036 variant specifically denotes the 72-position configuration. The series is characterized by its robust construction and compatibility with standard double-sided PCBs. It serves as a foundational interconnect solution in modular electronic systems.

Replacement Considerations

Direct substitutes must match the 72-position count, 0.156-inch pitch, and dual-edge female configuration. Verify identical mounting style and PCB thickness tolerance. Cross-reference with other EDAC 306 series parts or equivalent industry-standard connectors ensuring compatible contact material and plating specifications.
