Pin-to-pin option

SN74LVC1G125DBVR

Texas Instruments

Pin-to-pin P2P drop-in for the obsolete onsemi NC7SZ125. Same SOT-23-5 footprint, same pinout (1=OE, 2=A, 3=GND, 4=Y, 5=VCC), same 3-state buffer function, similar propagation delay (~2.5 ns at 3.3 V vs ~2.0 ns for NC7SZ125). The SN74LVC1G125 family from TI is the industry-standard cross-vendor alternative and the recommended direct replacement per Z2Data and Ovaga part cross-reference. Operating voltage range is identical (1.65 V to 5.5 V). onsemi has marked NC7SZ125 as 'DISCONTINUED' in the official datasheet (Rev. 4, Page 5).

SN74AUP1G125DBVR

Texas Instruments

Pin-to-pin P2P drop-in for the obsolete onsemi NC7SZ125 from TI. SN74AUP1G125DBVR is the TI AUP-family single bus buffer gate in SOT-23-5 with identical pinout (1=OE, 2=A, 3=GND, 4=Y, 5=VCC). Listed in TI's Little Logic Guide as the cross-reference for the NC7SZ family. Lower-power variant of LVC with 0.8 V to 3.6 V VCC range; compatible at the 1.8 V to 3.3 V operating range where NC7SZ is typically deployed. Recommended when the application is in the 1.8 V core logic domain.

Function alternative

SN74AHC1G125DBVR

Texas Instruments

Functional alternative to the obsolete onsemi NC7SZ125. SN74AHC1G125DBVR is the TI AHC (Advanced High-Speed CMOS) single bus buffer gate in SOT-23-5 with the same pinout and 3-state output enable as NC7SZ125. AHC family operates at 2 V to 5.5 V VCC and provides higher output drive (±8 mA) than UHS NC7SZ. Same 3-state buffer function but functionally equivalent for applications where the higher drive is acceptable. Use as drop-in when design needs more output drive than the low-power NC7SZ can deliver.

Function alternative

74AUP1G125GW

Nexperia

Functional low-power alternative to the obsolete onsemi NC7SZ125. 74AUP1G125GW is the Nexperia AUP (Advanced Ultra-low Power) single bus buffer gate in SOT-23-5 with identical pinout to NC7SZ125. Operates 0.8 V to 3.6 V VCC, <1 uA quiescent current, ~0.9 ns propagation delay. Same 3-state buffer function, lower power envelope than NC7SZ's UHS family. Use as drop-in for battery-powered and low-leakage applications where NC7SZ's UHS current is excessive.

Cross-reference FAQ

Replacement Part Questions

Short answers for teams reviewing NC7SZ125 replacement and equivalent-part options.

What is a cross-reference page for NC7SZ125?

This page groups mapped replacement options for NC7SZ125 so buyers and engineers can compare alternatives before requesting a quote or approving a substitute.

Does a mapped alternative mean a guaranteed drop-in replacement for NC7SZ125?

Not automatically. Cross-reference mapping helps shortlist candidates, but package, electrical behavior, qualification scope, and approval rules still need to be checked before release.

Which parameters should teams compare first for NC7SZ125 alternatives?

Start with package, series, key attributes, lifecycle status, stock position, datasheet access, and the mapped pin-to-pin or cross-reference note. Then confirm application-specific requirements in the datasheet and RFQ stage.

Can I request a quote for an alternative to NC7SZ125?

Yes. Use the product links or RFQ actions on this page to request pricing, availability, documentation, and sourcing support for any listed alternative part.

Is NC7SZ125 obsolete, and what replacement should buyers review first?

Check the lifecycle row on this page first. If buyers need a fast starting point, the strongest mapped replacement currently surfaced here is SN74LVC1G125DBVR, followed by the other alternatives shown in the comparison table.
