Current, voltage, and the signal-power boundary
The tin-on-tin contact interface (mating and post) is rated for moderate cycle counts; in a field-service application cycled monthly, expect several hundred mates before wear-through.

Buyers must confirm electrical and mechanical fit for their PCB layout before ordering.
Regulatory compliance and thermal environment requirements are critical for design validation.
Sourcing buyers need immediate availability and cost data to fill BOM lines.
Engineers compare variants to select the correct number of positions or features for the application.
Mechanical clearance constraints in the enclosure must be verified before purchase.
Connection reliability and locking mechanism are key for vibration-prone applications.
