What risks should I check before replacing NCP114ASN250T1G?

Before replacing, you must check two main things: 1) The package footprint, as many alternatives are SOT-23-5 instead of TSOP-5. 2) The minimum input voltage (Vin), as most alternatives require a higher voltage (2.0V or more) than the target's 1.7V, which could affect operation in low-voltage applications.

NCP114ASN250T1G Alternatives, Datasheet & Cross Reference | onsemi

Find alternatives for the onsemi NCP114ASN250T1G, a 2.5V 300mA LDO in a TSOP-5 package. Analysis shows a clear upgrade path and several functional alternatives, with key differences in package and input voltage to consider.

AI replacement insight

Package riskhigh

Many alternatives are in SOT-23-5, not TSOP-5. Footprint and pinout must be verified.

Electrical riskmedium

Most alternatives require a higher minimum input voltage (2.0V-2.7V) than the target's 1.7V.

Sourcing risklow

Multiple vendors offer LDOs with similar core specs, providing sourcing flexibility.

Can it be replaced directly?

Direct replacement for NCP114ASN250T1G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The best path is to migrate to the NCP164 family from onsemi, which is a next-generation part in the same TSOP-5 package with similar electricals and better performance.

Main risk

The primary risks are package incompatibility (TSOP-5 vs. SOT-23-5) and higher minimum input voltage requirements on most alternatives.

Recommended alternatives

Functional alternate with higher output current (500mA), but in a different package (SOT-23-5) with a higher Vin_min.
