HP compatible 849442-001 Description
EdgeOptic's 849442-001 compatible is an HPE-coded spare-channel version of the EdgeOptic 25G-SFP28-100 multi-vendor 25GBASE-SR SFP28 transceiver. 849442-001 is HPE's spare-part (SPS) ordering code for the same physical 25Gb SFP28 SR 100m module that HPE ships as the 845398-B21 option kit. HPE PartSurfer and reseller cross-references list 849442-001 alongside 845398-B21 for field-replacement and warranty fulfillment.
Optical behavior: 850 nm VCSEL transmitter, PIN photodiode receiver, TX power −5 dBm minimum and +2.4 dBm maximum, RX sensitivity −10.3 dBm, 5.3 dB link budget. Reach is 100 m on OM4, 100 m on OM5, and 70 m on OM3 multimode fiber with an LC/UPC duplex connector. Compliant with IEEE 802.3by Clause 112 for 25GBASE-SR; host RS-FEC RS(528,514) per IEEE 802.3by Clause 108. Electrical interface follows SFF-8431 and SFF-8432, DDM is SFF-8472 compliant, power dissipation 0.3 W maximum, 0 to 70 °C commercial operating range.
The ordering split between 849442-001 and 845398-B21 is the most common procurement question for this module. HPE issues 845398-B21 as the option-kit SKU when a new ProLiant chassis is configured with 25G SFP28 ports at order time, and reserves 849442-001 for HPE Services spare-parts orders, RMA fulfillment and field replacements on systems already in service. The two numbers resolve to the same physical transceiver; the channel the order travels through determines which code appears on the paperwork and warranty record.
Platform context covers HPE ProLiant servers with 25G SFP28 adapter cards. Verify against the HPE Server Hardware Compatibility Matrix and the per-chassis QuickSpecs for adapter-to-chassis qualification on the specific ProLiant generation in scope. The 849442-001 compatible programs with HPE-coded EEPROM so the iLO module-identification path inventories the optic against the expected HPE part identity on default ProLiant firmware images.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For matched-lot HPE spare-channel stock or cross-reference against the 845398-B21 option-kit code, contact our sales team.
Frequently Asked Questions about 849442-001
Is HPE 849442-001 the same physical module as 845398-B21?
Yes. 849442-001 is HPE's spare-part (SPS) ordering code and 845398-B21 is the option-kit ordering code for the same 25Gb SFP28 SR 100m transceiver. Two numbers, one physical module routed through two HPE order channels: 849442-001 covers field-replacement and spares fulfillment; 845398-B21 covers option-kit configuration on new ProLiant systems. HPE PartSurfer and multiple reseller cross-references list the parts as interchangeable shipments.
When should procurement order 849442-001 versus 845398-B21?
Use 849442-001 for HPE Services warranty replacement, field-spare RMAs and parts-on-hand stocking; HPE Services systems typically render the spare against this code. Use 845398-B21 when a new ProLiant system is being configured with 25G SFP28 ports and the optic appears as an option-kit line on the bill of materials. The shipped transceiver is identical; only the procurement channel changes.
Will the 849442-001 compatible raise an unsupported-transceiver event in iLO?
No. The 849442-001 compatible is programmed with HPE-coded EEPROM, so the optic registers cleanly through the iLO module-identification path on default ProLiant firmware images. For environments running hardened asset-inventory or strict optical-validation policies, verify the expected vendor and PN strings against the local policy and the HPE Server Hardware Compatibility Matrix for the chassis.
