Procurement Notes

Verify the specific contact count and pin configuration against the official datasheet before procurement. Confirm that the housing material and termination type match the design requirements. Ensure compatibility with mating male headers regarding pitch and alignment. Check for any specific ordering suffixes that may alter physical dimensions or electrical ratings. Validate supplier authorization to guarantee component authenticity.

Selection Notes

Select this component when a single-row female header with 2.54 mm pitch is required for vertical board stacking. Consider the 12A current rating and 100V voltage limit for circuit compatibility. Evaluate the through-hole mounting method against surface-mount alternatives based on mechanical stress requirements. Assess the operating temperature range for environmental suitability. Verify housing material properties for chemical resistance needs.

Part Context

This connector belongs to the AW 127 series by ASSMANN WSW Components, a manufacturer specializing in standard and custom connectors. The series is designed for general-purpose electronic applications requiring reliable interconnections. ASSMANN WSW provides system solutions including cable harnesses and heat sinks alongside discrete components.
