Overview
The EDAC Inc. 306-019-521-158 is a dual-edge female card edge connector featuring 38 positions arranged in two rows of 19. It utilizes a 0.156-inch (3.96mm) contact spacing and accepts PCB thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The contacts are made of copper alloy with a gold finish, ensuring reliable conductivity. Designed for panel mount through-hole termination, the unit operates within a temperature range of -40°C to 105°C and features a green thermoplastic polyester insulator.
Feature Summary
- Dual-edge configuration with 38 total positions for high-density interconnect applications
- Gold-plated copper alloy contacts provide corrosion resistance and stable signal transmission
- Panel mount installation with flange characteristics including flush mounting and top opening
- Thermoplastic polyester insulation ensures durability across a wide operating temperature range
Applications
- Industrial control systems requiring robust board-to-board connectivity
- Telecommunications equipment utilizing standard card edge interfaces
- Test and measurement instruments needing reliable dual-row connections
- Automotive electronics modules compatible with specified PCB thicknesses
Procurement Notes
Verify that the target printed circuit board thickness falls strictly within the 0.054 to 0.070 inch range to ensure proper mechanical engagement. Confirm that the application environment remains within the -40°C to 105°C operational limits. Ensure compatibility with the 0.156 inch pitch and dual-edge card type before finalizing procurement specifications.
Selection Notes
Select this component when a dual-edge female connector with 0.156 inch spacing is required for panel-mounted applications. The 38-position count suits designs needing two rows of 19 contacts. Verify that the host system supports through-hole termination and accommodates the specific flange dimensions for secure mounting.
Part Context
This part belongs to the EDAC 306 series, which specializes in card edge connectors with 0.156 inch spacing. The series offers various position counts and termination styles. The 306-019-521-158 specifically denotes a dual-edge female variant with gold contacts and a green insulator body, designed for general-purpose industrial use.
Replacement Considerations
Cross-reference with other EDAC 306 series parts sharing the 0.156 inch pitch and 38-position count. Verify identical flange mounting requirements and PCB thickness tolerances. Ensure any substitute maintains the same dual-edge female contact configuration and through-hole termination method.
