Component lead-time management begins by separating the dates that a production plan depends on. An estimated dispatch date, a supplier's acknowledged schedule and material received at the factory are different milestones. Track them explicitly for every critical BOM line instead of treating one generic lead-time field as the whole plan.
Work backward from the build date
Define when accepted material must reach the assembly site, allowing time for receiving checks and any agreed preparation. Then identify the required shipment date and the decision deadline for unresolved purchases. Keep transit assumptions separate from the supplier's readiness date.
Record the source and timestamp of each availability statement. A quote may describe material that has not been reserved, while an order acknowledgment may still contain conditions. Ask for clarification when dates are expressed as estimates, ranges or weeks after an unspecified event.
Check lifecycle events alongside availability
TI's product lifecycle page distinguishes active, not-recommended-for-new-designs, last-time-buy and obsolete statuses. These categories describe lifecycle, not the delivery date of a particular quantity. Review the exact device's status and any relevant notice when planning future builds.
TI's quality FAQs explain that an end-of-life notice communicates last-buy and final-delivery dates. For any manufacturer, retain the actual notice and identify the affected order codes. Do not apply another product's deadline or a generic lifecycle assumption to the part you need.
Manage critical lines and alternatives visibly
Maintain a shortage view that shows required quantity, confirmed quantity, unresolved balance, current date evidence and next action. Prioritize parts that prevent a complete build, including low-cost connectors or passives with no approved substitute. A nearly complete BOM can still leave the line unable to start.
Prepare alternatives early enough for engineering review, samples and verification. Compare a partial build, a split shipment and a redesign using their actual constraints. Update the production plan when evidence changes rather than preserving an old date because it appeared in the first quotation.
Frequently asked questions
Does an active manufacturer status mean immediate stock?
No. Lifecycle status and availability are different facts. The exact quantity, packaging and delivery window still need a current quotation or order confirmation.
Should every long-lead part be bought far in advance?
Assess demand confidence, storage requirements, cash exposure and redesign risk before committing. Buffer decisions should reflect the product plan and an approved purchasing strategy, not a universal number of months.
