Procurement Notes
Verify the specific contact plating thickness and material composition against the official Harwin datasheet before finalizing procurement decisions. Ensure that the through-hole footprint dimensions on the target printed circuit board precisely match the manufacturer's recommended land pattern to guarantee proper solder joint integrity and mechanical stability during operation.
Selection Notes
Select this component when a reliable female socket interface is required for mating with standard pin headers in space-constrained designs. The gold plating offers superior performance in environments where oxidation resistance is critical. Consider the through-hole mounting requirement as it provides stronger mechanical retention compared to surface-mount alternatives for vibration-prone applications.
