|---|---|---|---|
| FFF Compatibility | The pinout matches the MC14001BCPG exactly, and it is housed in the identical 14-DIP (0.300-inch width) through-hole package footprint.Standard 14-PDIP plastic package with identical pitch, lead spacing, and physical outline.Both are standard buffered CMOS quad 2-input NOR gates operating within the 3V to 18V supply voltage range. | Features the identical 14-pin assignment and shares the standard 14-DIP (0.300-inch width) footprint.Packaged in the identical physical 14-PDIP layout.The CD4001UBE is an unbuffered gate (single-stage inversion), which exhibits lower gain and softer transfer characteristics compared to the buffered MC14001BCPG. | |
 AI Summary | MC14001BCPG by onsemi: NOR Gate IC 4 Channel 14-PDIP. | The CD4001BE is the direct, active drop-in replacement for the obsolete MC14001BCPG. It provides identical logical functionality, matches the package outline, and preserves the buffered output characteristics. This is the highest-confidence second-source option.
| The CD4001UBE is an unbuffered version of the quad 2-input NOR gate. While it shares the same physical footprint and voltage ratings, it should only be used as a replacement if the application does not rely on buffered gain or is explicitly designed for unbuffered logic.

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 MC14001BCPG 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 MC14001BCPG are the CD4001BE (Texas Instruments) and the CD4001UBE (Texas Instruments). Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the MC14001BCPG 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 MC14001BCPG (onsemi) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
