| FFF Compatibility | Identical standard 14-SOIC footprint with matching pin assignment.Matches standard SOIC-14 package physical dimensions (3.90mm width).Meets or exceeds all electrical parameters of the original Rohm part, including the identical 36V supply maximum and 2V minimum. | Identical standard 14-SOIC footprint with matching pin assignment.Matches standard SOIC-14 package physical dimensions (3.90mm width).The minimum supply voltage is 3V (or ±1.5V) compared to the original Rohm device which can operate down to 2V (or ±1.0V). | ||
 AI Summary | LM339DR by ROHM Semiconductor: Comparator Standard (General Purpose) CMOS, MOS, Open-Collector, TTL 14-SOIC. | Diodes Incorporated's AS339MTR-G1 is a highly compatible drop-in replacement that perfectly matches the 2V to 36V supply voltage capabilities of the obsolete Rohm device. It also provides an upgraded operating temperature range (-40°C to 85°C) and lower power consumption. This active lifecycle part is widely available as a direct replacement.
| The onsemi LM339DR2G is a widely used drop-in replacement that matches Rohm's maximum supply voltage rating of 36V. However, it requires a slightly higher minimum supply voltage of 3V rather than 2V. It is a highly active and widely stocked component suitable for most designs.

You searched one part. Parter watches your whole BOM.
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 ROHM Semiconductor LM339DR 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 ROHM Semiconductor LM339DR are the AS339MTR-G1 (Diodes Incorporated) and the LM339DR2G (onsemi), 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 LM339DR 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 LM339DR (ROHM Semiconductor) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
