845-072-525-103

Edgeboard Connectors Overview

The EDAC Inc. 845-072-525-103 is a standard card edge connector from the 845 series, designed for single-edge board applications. It features 72 positions with a 0.100 inch (2.54 mm) pitch and utilizes gold-plated contacts on a copper alloy base. The component supports a maximum operating temperature of +125°C and a minimum of -40°C. It employs a panel mount style with a right-angle orientation and solder pin termination. The housing is constructed from Diallyl Phthalate (DAP), providing insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Gold-plated cantilever contacts ensure reliable signal transmission in high-temperature environments.
• Diallyl Phthalate (DAP) housing provides robust electrical insulation and thermal stability.
• Right-angle panel mount design facilitates efficient space utilization in vertical configurations.

Edgeboard Connectors Applications

• High-temperature industrial control systems
• Military and aerospace electronic assemblies
• Automotive electronics requiring thermal resilience

Edgeboard Connectors Procurement Notes

Verify the specific suffix code to confirm contact plating thickness and material specifications, as variations exist within the 845 series. Confirm that the right-angle orientation matches the mechanical layout requirements. Ensure the 72-position count aligns with the target PCB edge profile. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this model when a single-row, right-angle connection is required for thick PCBs up to 1.57 mm. The 0.100-inch pitch suits standard digital and analog signal routing. Consider the 3A current rating per contact for power distribution needs. Verify that the DAP material compatibility meets the chemical exposure conditions of the intended environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 845 High Temp Series, engineered for demanding operational conditions. The series offers various position counts and mounting styles. The 845-072 variant specifically addresses applications needing dense connectivity in a single row. It complements other EDAC connectors by providing standardized dimensions and reliable performance under thermal stress.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers such as 845-072-525-602 or 845-072-525-201 for potential substitutes. Verify that any replacement maintains the same 72-position count and 0.100-inch pitch. Ensure the mounting angle and termination type are identical to avoid mechanical redesign. Confirm that the contact material and insulation properties match the original specifications.
