Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number with official datasheets. Confirm RoHS compliance status and check for specific ordering suffixes that may alter function or packaging. Ensure the supplier provides valid traceability documentation for this discontinued or limited-stock item.
Selection Notes
Select this component when a compact, high-reliability solution is required for vertical board-to-board connections. The 1.25 mm pitch allows for dense pinout configurations while maintaining a 2 A current capacity. Consider the jackscrew feature if vibration resistance and secure mating are critical operational requirements.
