Buyer scenario
One suffix difference can change package, temperature grade or lifecycle status. In power / pmic / dc-dc / gate driver RFQs, buyers should confirm package, suffix, date-code policy and lead time before comparing supplier offers.
Relevant RFQ examples on this site include ISL99380FRZ-TR5935, ISL99390FRZ-TR5935, L9369-TR, TPS565201DDCR, TPS54331DR.
What suffixes can change
Power Management demand often looks simple in a spreadsheet, but the quote can change once package verification, delivery timing and alternative part review begin.
Buyer checklist
Package evidence to request
Risk review table
| Check | Buyer question | Action |
|---|---|---|
| Package | Does the suffix match the approved BOM? | Verify before price comparison |
| Lead time | Is the delivery date realistic? | Confirm before PO planning |
| Documents | Can the supplier share useful evidence? | Request photos for high-risk lines |
| Alternates | Has engineering approved the change? | Hold quote until reviewed |
