Not every search needs a full BOM paste. Single MPN search is built for line-down emergencies and quick price checks. Bulk BOM mode is built for kitting, NPI builds, and quarterly sourcing reviews — similar to how advanced BOM portals extend basic part search tools.
Use single search for one-line emergencies
When production stops on one MPN, search that part number directly, open matching listings, and request a quote or place an order if pricing is published.
Use bulk BOM for coverage analysis
When you need to know how many of 200 lines are covered by US suppliers, paste the full list once and review hits vs misses. That coverage map drives broker calls and redesign decisions.
Combine with describe-a-part smart search
During early design before MPNs are frozen, smart search helps you discover candidate parts. Once MPNs are fixed, switch to BOM mode for procurement.
