| FFF Compatibility | Both use the industry-standard DO-214AB (SMC) 2-terminal package with identical polarity and terminal layouts.The dimensions, pad layout, and package type are identical.The electrical ratings meet or exceed the original, with 100V reverse voltage, 3A forward current, and identical thermal limits. | Both utilize the standard DO-214AB (SMC) package.Standard SMC mechanical package dimensions match perfectly.Offers superior electrical performance across leakage, forward voltage, and thermal ranges compared to the original part. | ||
 AI Summary | S310_NL by onsemi: Schottky Diodes & Rectifiers 100V, 3A SCHOTTKY BARRIER RECTIFIER IN SMC. | This is the direct active successor to the obsolete S310_NL. The '_NL' suffix was used during Fairchild's transition to lead-free (No Lead) processes, while the active onsemi 'S310' part number is RoHS-compliant by default.
| An excellent higher-grade alternative from the same manufacturer that improves upon several critical electrical characteristics. It features lower reverse leakage and a wider operating temperature range, making it highly robust.

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 onsemi S310_NL 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 onsemi S310_NL are the S310 (onsemi) and the MBRS3100T3G (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 S310_NL 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 S310_NL (onsemi) is a part in the Schottky Diodes & Rectifiers category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
