NVIDIA MMS1X00-NS400 has 2 recorded cross-reference matches across 2 manufacturers. Research equivalent, alternate or similar parts using the listed candidates, and check their source notes before selecting a replacement.
NVIDIA MMS1X00-NS400 versus AddOn Networks MMS1X00-NS400-AO:
AddOn indexed manufacturer listing explicitly names MMS1X00-NS400-AO as compatible with NVIDIA/legacy Mellanox MMS1X00-NS400; product family 400G QSFP112 DR4. Direct AddOn page retrieval returned HTTP 403 on 2026-10-31; indexed publisher evidence was retained, and current live-page availability was not independently established. 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.
NVIDIA MMS1X00-NS400 versus Amphenol ProLabs MMS1X00-NS400-C:
ProLabs explicitly identifies MMS1X00-NS400-C as compatible with legacy Mellanox/NVIDIA MMS1X00-NS400. Published configuration: 400GBase-DR4 QSFP112, 1310 nm, MPO, up to 500 m on single-mode fiber, CMIS 5.0. Supplier-published compatibility claim, not NVIDIA qualification or independent drop-in approval. Confirm exact switch/NIC, firmware, Ethernet versus InfiniBand mode, host coding, electrical lanes, FEC, management interface, power/thermal limits, connector/polarity, fiber, reach and operating temperature before substitution. No numeric NVIDIA code mapping or supplier-to-supplier equivalence is inferred. 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.
MMS1X00-NS400 replacement and similar-part research
Looking for an equivalent or alternate to NVIDIA MMS1X00-NS400? 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.
