Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact termination type and material variations. Ensure compatibility with target PCB thickness and panel cutout dimensions before procurement. Cross-reference RoHS compliance status with the latest manufacturer declarations. Confirm availability through authorized distributors as supply chains may fluctuate. Validate that the selected variant matches the required electrical ratings for the intended application environment.

Edgeboard Connectors Selection Notes

Select this component when a robust dual-row card edge solution with high current capacity is required. The 3.96 mm pitch accommodates standard thick PCBs, making it suitable for heavy-duty industrial environments. Consider the gold plating for corrosion resistance in harsh conditions. Evaluate the panel mount requirement against space constraints. Ensure the operating temperature range aligns with the environmental conditions of the final assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options to support diverse electronic design needs. The 305 series is characterized by its durable construction and reliable performance in demanding applications. It serves as a critical interconnect solution for modular electronic systems requiring frequent maintenance or expansion.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row configurations but different position counts, such as 305-018-521-202 or 305-038-521-202. Verify mechanical fit and electrical ratings before substitution. Alternative manufacturers may offer similar connectors, but pin alignment and housing dimensions must be strictly validated.
