846-090-526-203

Edgeboard Connectors Overview

The EDAC Inc. 846-090-526-203 is a dual female card edge connector from the 846 high-temperature series. It features 90 positions arranged in two rows with a 0.125-inch (3.18mm) pitch. The contacts are gold-plated copper alloy, and the housing is made of green Diallyl Phthalate (DAP). Designed for through-hole termination, it supports PCB thicknesses between 0.054 and 0.070 inches. The unit operates within a temperature range of -40°C to +125°C.

• Gold-plated contacts for reliable conductivity
• Flush mount flange with floating bobbin design

Edgeboard Connectors Applications

• Industrial control systems requiring thermal stability
• Communication equipment backplanes
• Automotive electronics modules
• Medical device interconnects

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC datasheet to confirm pin count, plating thickness, and flange specifications. Ensure the ordering part number matches the required dual-row configuration and mounting style. Cross-reference the manufacturer's latest documentation to confirm current production status and compliance certifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge connection is required in thermally demanding environments. The 0.125-inch pitch accommodates standard board layouts while the DAP housing provides robust insulation. Ensure the target PCB thickness falls within the specified 0.054 to 0.070-inch range for proper mechanical engagement and electrical contact reliability during operation.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 846 series, which is engineered for high-temperature applications exceeding standard industrial limits. The series utilizes Diallyl Phthalate (DAP) for superior thermal stability compared to standard thermoplastics. This specific model represents a high-position-count variant designed for complex signal routing in compact form factors.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 90-position dual-row layout and 0.125-inch pitch. Verify that alternative components support the same -40°C to +125°C operating range and utilize compatible DAP or equivalent high-temp housing materials. Ensure mechanical compatibility with flush mount flanges and floating bobbin features if alignment tolerance is critical.
