Amphenol PCD ELM0X3200 versus BlockMaster MSMXX045:
PDF page 1, table 1, row 27. Manufacturer-published series/pattern comparison; no complete pole-count variants generated. Manufacturer/brand label is the historical source attribution; the guide does not establish current corporate ownership. Grouped labels retain the source group rather than guessing a single manufacturer. Series/pattern reference only; X/XX and other unspecified pole-count/ordering options remain exactly as printed and must be resolved before selecting a part. Published research candidate, not an approved drop-in replacement. Verify current exact ordering codes, pitch, poles, wire range, electrical ratings, dimensions, PCB footprint, pinout, mounting, mating interfaces, coding, material, approvals and required jumpers/end covers/markers. Accessories and pluggable halves are not assumed interchangeable. A reverse lookup preserves the published relationship, not reverse replacement approval.

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.
MSMXX045 series comparison
These series references are starting points for comparing product families. Select and verify the complete ordering code.
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.
