| FFF Compatibility | Matches the exact 6-TSOC package pinout with DATA on pin 2 and GND on pin 1.Identical 6-pin TSOC package physical dimensions.Provides the identical 1Kb 1-Wire memory, but does not come preprogrammed with the EUI-48 MAC address from the factory; programming must be handled by the user. | Uses the identical 6-TSOC package pinout with DATA on pin 2 and GND on pin 1.Identical 6-pin TSOC package dimensions.Acts as a unique identifier on the 1-Wire bus, but lacks the 1Kbit user EPROM and does not format the 48-bit serial ID as an EUI-48 standard address. | ||
 AI Summary | DS2502P-E48+ by Analog Devices: EPROM - OTP Memory IC 1Kbit 1-Wire® 6-TSOC. | The DS2502P+ is the unprogrammed equivalent sibling of the DS2502P-E48+. It offers a physical and electrical drop-in replacement, but requires manual programming to write a custom MAC address as it does not come pre-configured from the factory.
| If the DS2502P-E48+ was used solely as a unique hardware identifier (serial number/node ID) without utilising the 1Kb EPROM space, the DS2401P+ is an ideal drop-in replacement. It provides a unique, factory-lasered registration number over the 1-Wire protocol.

All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Analog Devices DS2502P-E48+ is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Analog Devices DS2502P-E48+ are the DS2502P+ (Analog Devices Inc./Maxim Integrated) and the DS2401P+ (Analog Devices Inc./Maxim Integrated), out of 4 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the DS2502P-E48+ are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The DS2502P-E48+ (Analog Devices) is a part in the Memory category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
