| FFF Compatibility | The part is the exact same silicon and package (SO16/SOT109-1) from Nexperia, with the only difference being the high-volume Tape & Reel packaging (suffix 653) instead of the obsolete Tube packaging (suffix 652).Both parts share the exact same physical body dimensions (16-SOIC, 3.90mm width) and mounting specifications.The electrical parameters, propagation delay (25 ns), supply range (2V to 6V), and temperature rating (-40°C to 125°C) are identical. | Shares the identical 16-SOIC physical footprint and pin configuration with the target part.Symmetric 16-SOIC package with matching 3.90mm (0.154") body width.Matches all critical electrical performance ratings, input logic thresholds, and timing specs of the original device. | ||
 AI Summary | 74HC4538D,652 by Nexperia: Monostable Multivibrator 25 ns 16-SO. | This is the direct drop-in replacement from Nexperia, differing only in the packaging option (Tape & Reel instead of Tube). It represents the safest and lowest-risk migration path for active designs.
| Toshiba's standard version is a highly reliable second-source alternative that matches the target part in package dimensions, pinout, and key timing specifications. It is in active production and widely stocked.

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 Nexperia 74HC4538D,652 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 Nexperia 74HC4538D,652 are the 74HC4538D,653 (Nexperia USA Inc.) and the 74HC4538D (Toshiba Semiconductor and Storage), 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 74HC4538D,652 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.
