Baldwin Form 560-24 Manufacturers' Cross-Reference, printed page 276, column 5; one clean same-line ordering-code row. Baldwin states the guide is for general reference and that application decisions remain the installer's responsibility. Manufacturer-listed comparison, not independently certified drop-in equivalence. Verify current application, dimensions and mounting, connections/threads, seals and gasket needs, filter medium, filtration and flow ratings, bypass/collapse pressure, temperature, approvals and any required housing or accessories. Original-to-Baldwin recommendation; reverse lookup retains this orientation and does not approve reverse substitution. No competitor-to-competitor inference. Rows carrying gasket/housing symbols, alternatives, variations, conditions, clean-and-reuse or lost-UL notes were held out of this batch.
Donaldson Truck & Bus Cross Reference List, printed page 981, column 2; one literal OEM ordering code aligned with one literal Donaldson ordering code and independently corroborated with a second PDF text extractor. Historical manufacturer-authored lookup reference only; confirm the actual vehicle, engine and equipment application. Current dimensions, mounting, threads/connections, seals, media, filtration/flow, bypass/collapse pressure, temperature, approvals and availability were not independently verified. Exact printed ordering-code spaces are preserved. Source orientation is OEM-to-Donaldson; do not infer competitor-to-competitor equivalence or aviation suitability.

Find additional research candidates through a shared connecting part. Each result is labeled Second-degree candidate · Unverified and shows both recorded source relationships.
Two recorded crosses do not establish a verified equivalent. Compare current specifications, interfaces, ratings, cable requirements and the same PCB footprint or panel fit before substitution. Candidate counts are separate from direct-cross and part totals.
P550861 replacement and similar-part research
Looking for an equivalent or alternate to DONALDSON P550861? The 12 recorded candidates above link to individual part pages and the evidence behind each relationship.
A recorded cross reference does not establish a drop-in replacement. Compare current datasheets, package or mounting dimensions, pinout, electrical ratings and operating conditions for your application. Similar parts can differ in critical specifications.
Counts describe recorded relationships, not stock, sales, testing or independent qualification. Manufacturer-and-part identities remain separate. Indexing dates do not establish current specifications or availability.
Check current manufacturer documents and electrical, mechanical, environmental and application requirements before selecting a replacement.
