PNY PMA1B00-C100D has 2 recorded cross-reference matches across 1 manufacturer. Research equivalent, alternate or similar parts using the listed candidates, and check their source notes before selecting a replacement.
PNY ordering-information table directly lists PNY PMA1B00-C100D, legacy Mellanox MMA1B00-C100D and NVIDIA numeric SKU 980-9I149-00CS00 in the same row. These two NVIDIA numbering identities refer to the same referenced OEM product, not two distinct hardware models. Published description: 100% Mellanox Compatible transceiver, 100GbE, QSFP28, MPO, 850nm, SR4, up to 100m, DDMI 5 Year Warranty. The base SKU is the printed five-year-warranty option; the -10 warranty variant is not silently substituted. Supplier-published compatibility claim, not NVIDIA qualification or independent drop-in approval. Confirm the exact switch/NIC, firmware, Ethernet versus InfiniBand mode, host coding, port electrical lanes, FEC, CMIS/DDM version, power/thermal limits, connector/polarity, fiber, reach and operating temperature before substitution. Reverse lookup does not establish reverse replacement suitability. Excluded from second-degree inference pending exact host/configuration review.

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.

Looking for an equivalent or alternate to PNY PMA1B00-C100D? The 2 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.
