Catalog selection insight

One-line delta from headline spec rows — screening language only, not a suitability or substitution decision.

6ES72266BA320XB0: supply / I/O voltage headline differs from 6ES76470BA001YA2 (24VDC vs 12VDC, 24VDC) — re-check fuse sizing, surge rating, and SELV/PELV boundaries. 6ES72266BA320XB0: headline supply differs from 6ES76470BA001YA2 — treat as a different electrical platform until PSU, protection, and I/O are revalidated (not a same-rail swap by catalog text alone).

Technical screening notes (catalog snapshot)

Deterministic text from normalized spec keys — not live field-application-engineering advice or manufacturer sign-off.

Technical screening note for 6ES72266BA320XB0 vs 6ES76470BA001YA2: this catalog snapshot lacks obvious isolation/EMC/protocol rows — expand the PDP specification table or open the PDF for creepage, surge, and bus timing before any design change.

Catalog screening tiers (heuristic)

Three non-authoritative screening tiers (mechanical token, functional checklist, planning notes) mirror the JSON-Ld ItemList on this page — not manufacturer substitution letters or field approvals.

Mechanical / packaging row (not interchange)
Headline rows in this catalog snapshot differ on supply, fieldbus/protocol, and/or compute — **do not** read that as interchange, drop-in, or “safe substitute” from distributor text alone. Packaging or mechanical tokens also differ or are too generic to infer fit — treat as independent SKUs until qualified in your system.
Warning: Supply / IO voltage text differs (24VDC vs 12VDC, 24VDC).
Functional screening checklist
Run isolation, supply, bus timing, software/runtime, and mechanical checks against your deployed baseline. Catalog differences above block any “equivalent part” claim from this page.
Warning: Supply / IO voltage text differs (24VDC vs 12VDC, 24VDC).
Design-change planning notes
If you intend a product change, favor wider temperature, higher isolation withstand, or newer fieldbus only **after** manufacturer guidance, software licensing, and enclosure clearance are confirmed — not from this matrix alone.

Tool-style compare: isolation, supply, IP, rail, fieldbus, and EMC rows are surfaced first when present. Open each PDP for PDF revisions and RFQ.

Compatibility screening (catalog text)

Same deterministic tiers as the compare module above — for engineering checklists only, not approved alternates. Supply, protocol, and processor headline mismatches surface as warnings when present.

Technical compliance & certifications

Values below are extracted from normalized catalog specification keys and brand-level certification lists (where present). They mirror manufacturer datasheet legends when those strings were captured in the catalog row — not a certificate download. This page was machine-aligned on 2026-05-13 for technical selection support only; it is not the sole basis for installation or safety sign-off in your jurisdiction.
