One manufacturer designation, every identity it carries: 1 stock number.
The codification catalogue keys on the item of supply — each stock number opens the catalogue's own family, with approved sources and order of use.
Order of use is the catalogue's, not ours. Every member opens its own part-number family.

Other designations qualified to the same line. A different size or class on one document is a NEIGHBOUR, not a substitute — ABS5093B25 (25 mm) and ABS5093B485 (485 mm) share a specification and are not swaps for each other. Each names the line that vouches for it.
Nothing else is published on these lines yet — coverage grows with each qualified-products cycle.
Codification and qualification say who vouches for a part — they are not installation eligibility. Under EASA Part-21, eligibility flows from the approved design (type design / IPC) or an approved change; under Part-145, acceptance needs an EASA Form 1 or, for genuine standard parts, conformity traceable to the officially recognised standard (145.A.42).
Stage 1(a): we assemble the equivalence/identicality starter file — the cited evidence this graph holds, shaped for your DOA or compliance department to take forward. See pricing.
Regulatory explainer, not legal advice: paragraph numbers, derogations and the BASA/TIP revision change — verify against the current consolidated Regulation (EU) 748/2012, the EASA Easy Access Rules and the current TIP, and engage your DOA and competent authority early.
This crosswalk identifies candidate equivalents with cited evidence. It is not an airworthiness approval. Substitution decisions remain subject to your organisation’s procurement and engineering approval process and the governing maintenance data (AMM/CMM/SRM/CML/OMAT).
