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.
49187 replacement and similar-part research
Looking for an equivalent or alternate to WIX 49187? The 40 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.
