| FFF Compatibility | The 16-pin assignments, functional designations, and 150-mil SOIC footprint match the original onsemi/Fairchild part exactly.Matches the 16-SOIC (0.154" / 3.90mm narrow body) package shape, dimensions, and SMD mounting style.Operates on the same 4.5V to 5.5V supply voltage range, includes TTL-compatible inputs, and provides the same 24mA drive strength. | Pin assignments and standard 16-SOIC (150-mil) package pin configuration match exactly.Matches the 16-SOIC physical dimensions and surface-mount configuration.While it supports TTL-compatible inputs and a 4.5V to 5.5V supply, the HCT technology has a lower output drive strength (4mA vs. 24mA) and slower propagation delays compared to ACT logic. | ||
 AI Summary | 74ACT151SCX_NL by onsemi: Encoders, Decoders, Multiplexers & Demultiplexers 8-Input Multiplexer. | The CD74ACT151M96 is an active, highly reliable direct drop-in replacement from Texas Instruments. It belongs to the same 74ACT logic family, ensuring identical high-speed performance, 24mA drive capabilities, and full TTL logic level input compatibility without requiring any schematic or layout modifications.
| This is an active 74HCT-series alternative from Nexperia that provides direct physical compatibility. It is ideal for lower-speed and lower-drive applications, but designers must verify that the reduced output drive (4mA vs. 24mA) and slower propagation delays are acceptable for their specific system requirements.

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 74ACT151SCX_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 74ACT151SCX_NL are the CD74ACT151M96 (Texas Instruments) and the 74HCT151D,653 (Nexperia USA Inc.), out of 3 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 74ACT151SCX_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 74ACT151SCX_NL (onsemi) is a part in the Encoders, Decoders, Multiplexers & Demultiplexers category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
