FILTRON K 1331 has 1 recorded cross-reference match across 1 manufacturer. Research equivalent, alternate or similar parts using the listed candidates, and check their source notes before selecting a replacement.
WIX 2019 master interchange, printed page 223, column 6; literal source row corroborated with a second text extractor. Exact WIX target and filter style CAPS checked in the separate product index (printed page 827). Historical manufacturer-listed reference for lookup only; confirm the vehicle/equipment application. Not independently verified drop-in equivalence, current availability or aviation suitability. Verify current dimensions/mounting, connections/threads, seals, medium, filtration/flow, bypass/collapse pressure, temperature and required accessories. Full current datasheet/drawing comparison not performed. Original-to-WIX source orientation retained in reverse lookup; reverse substitution is not approved by this evidence. No competitor-to-competitor inference.
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.

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.
