Preserve the legacy configuration

Obsolete references often vary by firmware, revision, voltage, connector, mounting, and regional approval. Record the installed item and machine context before considering an alternative, repair, or surplus condition.

Evidence checklist

  • Complete legacy MPN and revision
  • Machine maker, model, and function
  • Backup or parameter availability
  • Alternative and condition policy

Mark unknowns for sourcing review

Do not fill gaps with assumptions. Identify which details came from the label, which came from a manufacturer document, and which still need confirmation during the RFQ review.

Evidence checklist

  • Confirmed identification facts
  • Buyer requirements
  • Open technical questions
  • Commercial terms requiring written confirmation

Recommended RFQ information

  • Exact brand name and part number
  • Required quantity and U.S. delivery state or ZIP code
  • New, surplus, replacement, or repair preference if known
  • Machine, line, or project context when it helps identify the part
  • Urgency, deadline, and any acceptable alternatives

Catalog presence is not a live-stock, fixed-price, compatibility, or distributor-status claim.

Buyer FAQ

Obsolete Industrial Parts Sourcing Guide questions

Does a PartsGo listing confirm stock or price?

No. Availability, pricing, condition, and lead time are confirmed only after the specific RFQ is reviewed.

What should a U.S. buyer always include?

Include the manufacturer, complete part number, quantity, delivery state or ZIP code, target lead time, and any available label, nameplate, or datasheet evidence.

Does a brand listing mean PartsGo is an official distributor?

No. Brand names and part numbers are used for identification and RFQ matching unless an explicit relationship is separately stated.
