305-016-521-512

Edgeboard Connectors Overview

The EDAC Inc. 305-016-521-512 is a dual-edge female card edge connector from the 305 series, designed for through-hole mounting. It features 16 positions with a 0.156-inch (3.96mm) pitch across two rows. The contacts are made of copper alloy with a gold finish and utilize a semi-crimping termination type. The housing is green thermoplastic polyester, rated for operation between -40°C and +105°C. It accepts board thicknesses from 0.054 to 0.070 inches.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card types
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic polyester insulation for thermal stability
• Through-hole solder pin termination for secure PCB attachment

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Automotive electronics modules
• Test and measurement instrumentation

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct contact plating thickness and housing color specifications. Confirm that the target application board thickness falls within the accepted range of 0.054 to 0.070 inches to guarantee proper mechanical retention and electrical contact. Check RoHS compliance status if required by project regulations.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 16-position interface is required with a standard 3.96mm pitch. Ensure the design accommodates through-hole assembly processes rather than surface mount alternatives. Consider the 5A current rating capability if high-power signaling is involved, and verify that the operating temperature environment remains within the specified -40°C to +105°C range for long-term reliability.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and mounting styles, providing flexibility for different board densities. The 305-016 variant specifically addresses applications needing a compact yet durable connection point for dual-sided edge cards.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series parts with identical pitch and row count but different position numbers or termination styles. Cross-reference with manufacturers offering similar 0.156-inch pitch dual-edge connectors, ensuring matching mechanical dimensions and electrical ratings for seamless integration.
