Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm exact pin count, pitch, and mounting style before procurement. Ensure compatibility with target PCB thickness ranges of 1.37 mm to 1.78 mm. Confirm RoHS compliance status matches project requirements. Cross-reference manufacturer datasheets for precise dimensional tolerances and mating force specifications.

Edgeboard Connectors Selection Notes

Select this component when high pin density is required within a standard 3.96 mm pitch framework. The straddle mount style offers superior stability compared to surface mount alternatives for heavy boards. Verify that the 5 A current rating meets circuit load requirements. Consider the availability of polarizing keys if specific orientation locking is necessary for the assembly process.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting options for diverse electronic applications. Components in this family share consistent electrical ratings and material specifications, ensuring interchangeability within defined mechanical constraints across different pin configurations.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series receptacles with matching 86-position layouts. Verify identical 3.96 mm pitch and straddle mount geometry for direct replacement. Ensure equivalent gold plating thickness and current ratings are maintained. Consult official cross-reference lists for confirmed alternative part numbers.
