Procurement Notes
Verify component obsolescence status before integration into new designs. Confirm availability through authorized distributors for existing production lines. Request latest datasheets to ensure compatibility with mating headers. Check for RoHS compliance documentation if required by project specifications. Evaluate alternative replacement parts due to end-of-life classification.
Selection Notes
Consider the single-row layout when planning PCB footprint dimensions. Ensure mating header selection matches the 2.54mm pitch and contact count. Verify surface mount soldering profile requirements for thermal management. Assess mechanical stability needs for the push-pull locking mechanism. Confirm insulation material suitability for operating environment temperatures.
