Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, contact material, and termination style. Ensure compatibility with mating connectors regarding pitch and locking mechanism requirements. Cross-reference the component marking with the official Harwin part number to prevent substitution errors during assembly.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a mixed signal and power solution is required in a straight, through-hole format. Consider the 2mm pitch and 20-position capacity for space-constrained designs. Evaluate the need for jack screw locking versus standard locking based on vibration environment requirements. Confirm that the operating temperature range aligns with the application's thermal profile.
