| FFF Compatibility | The pinout configuration is a 1-to-1 match (Pin 1: B2, Pin 2: GND, Pin 3: B1, Pin 4: A, Pin 5: VCC, Pin 6: S) in the same SC-88 footprint.Housed in an identical US6 / SOT-363 (SC-88) package with matching package physical dimensions.Acts as a 1 x 2:1 CMOS multiplexer/demultiplexer switch with equal or better electrical characteristics (including lower on-resistance and wider operating voltage). | The pin assignments are functionally identical to the target component, with control select input on Pin 6 and I/O channels on Pins 1, 3, and 4.Offered in the standard SC-70-6 (SOT-363 / SC-88) package with identical land pattern and body dimensions.Functions identically as a single SPDT analog switch/multiplexer with a typical on-resistance of 15 Ohms, meeting or exceeding all target specifications. | ||
 AI Summary | NC7SB3257P6X by onsemi: Multiplexer/Demultiplexer 1 x 2:1 SC-88 (SC-70-6). | The Toshiba TC7SB3157CFU is an active, highly reliable direct substitute for the obsolete NC7SB3257P6X. It is a drop-in replacement that shares the exact same package footprint, pinout, and multiplexing logic, while offering a wider supply voltage and operating temperature range.
| The Texas Instruments SN74LVC1G3157DCKR is a premier drop-in replacement that is fully active. It offers the exact same pinout and functionality in an identical SC-70-6 package, with improved supply voltage flexibility and wider thermal ratings.

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 NC7SB3257P6X 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 NC7SB3257P6X are the TC7SB3157CFU,LF(CT (Toshiba Semiconductor and Storage) and the SN74LVC1G3157DCKR (Texas Instruments), 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 NC7SB3257P6X 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 NC7SB3257P6X (onsemi) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
