Solution Procurement engineering

Compare the replacement
with the requirement behind it.

When a part goes obsolete, draft the item equivalency evaluation from both data sheets, with every critical characteristic cited and every gap left open for the engineer.

For procurement and design engineering. The procurement or design engineer keeps the decision.

The problem

A similar part number is only the beginning.

An obsolete component can leave procurement and engineering piecing together the original specifications, vendor information, operating context and previous substitutions.

  • Critical requirements are spread across the original technical record.
  • Candidate data may be incomplete or use different terms.
  • A missing qualification or interface value has to stay visible.
The workflow

How the work gets done.

Nuclearn Parts AI works the evaluation in stages from intake to package and stops for the engineer at every decision. It compares each critical characteristic from both data sheets and names the evidence gaps.

  1. IntakeConfirm the original item and the candidate.
  2. CharacteristicsList the critical characteristics and what each guards.
  3. CompareOriginal and candidate values, cited to their data sheets.
  4. GapsWhat neither data sheet states, and which document would close it.
  5. PackageThe evaluation, ready for the engineer's review.

What goes in

  • The original item and the candidate
  • Both data sheets
  • Specifications and equipment records
  • Prior evaluations

What comes out

  • A sourced evaluation draft, with open items named.
  • The output is always a draft. The engineer validates the comparison and approves the equivalency.
Illustrative case study

An obsolete valve, a candidate and an unanswered requirement.

The situation
A procurement engineer needs to evaluate a proposed replacement for a discontinued gate valve before the work package moves.
The work
The evaluation reads both data sheets, compares the critical characteristics, and flags seat leakage performance and bonnet joint construction as gaps neither sheet answers.
The result
The engineer gets a draft comparison and two specific open items to resolve with the vendor before deciding.
