COMPATIBILITY & CROSS-REFERENCE
HP part number 1901-1062 is a house number: Hewlett-Packard assigned its own part numbers to the semiconductors used in its instruments, so the HP number — not a commercial type number — is what appears in HP service documentation and parts lists. This device is additionally catalogued in United States federal supply data under NSN 5961-01-013-9353, within Federal Supply Class 5961 (semiconductor devices and associated hardware), as a 25A silicon stud-mount rectifier in a hermetically sealed case with a threaded UNF stud and solder-lug terminal. When servicing HP instruments, match the HP part number first. If substituting a commercial stud rectifier, confirm reverse voltage, average forward current, stud thread size and polarity — stud diodes are supplied in both standard and reverse-polarity versions, where the stud is either the cathode or the anode.

Q&A
Q: What is HP part number 1901-1062? A: An HP house-numbered silicon stud-mount rectifier diode rated 25A maximum average forward current, catalogued under NSN 5961-01-013-9353.
Q: How does it mount? A: By a threaded UNF stud, with a solder-lug terminal for the opposite connection; the stud carries the heat into the chassis or heatsink.
Q: Is the original HP packaging included? A: Yes — the diode ships in its original Hewlett-Packard Customer Service packaging as pictured.
