 AI Summary | MC74VHC1G05DFT1 by onsemi: Inverter IC 1 Channel Open Drain SC-88A (SC-70-5/SOT-353). | The SN74LVC1G06DCKR from Texas Instruments is an active, high-performance alternative to the obsolete MC74VHC1G05DFT1. It offers pin-to-pin compatibility in the same SC-70-5 package while providing higher current drive and a wider voltage supply range. However, it trades off a slightly narrower low-end operating temperature limit (-40°C vs -55°C).
| Nexperia's 74AHC1G06GW is an active and highly reliable second-source alternative that matches the original part's electrical limits such as 8mA output current and 2.0V to 5.5V supply voltage. It is a direct drop-in replacement in the same SOT-353 package, with a minor tradeoff on the lower temperature limit (-40°C vs -55°C).

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 MC74VHC1G05DFT1 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 MC74VHC1G05DFT1 are the SN74LVC1G06DCKR (Texas Instruments) and the 74AHC1G06GW (Nexperia), 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 MC74VHC1G05DFT1 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 MC74VHC1G05DFT1 (onsemi) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
