Is there a pin-compatible replacement for ULN2003D1013TR?

Many manufacturers produce ULN2003 variants in SOP-16/SO-16 packages that are often pin-compatible. However, you must always verify the candidate's datasheet to confirm the pinout matches your board layout before substitution.

What risks should I check before replacing ULN2003D1013TR?

Key risks include package footprint differences (SO-16 vs. SOP-16 body width), pinout mismatches, and variations in electrical characteristics like input voltage thresholds or saturation voltage, which can affect performance.

ULN2003D1013TR Alternatives, Datasheet & Cross Reference | STMicroelectronics

The ULN2003D1013TR is a popular 7-channel Darlington array for driving inductive loads. Alternatives from the same ULN2003 family are available in similar packages but require pinout and footprint verification.

AI replacement insight

Package riskmedium

SO-16 and SOP-16 can have different body widths; footprint verification is critical.

Electrical risklow

Key parameters are standardized for the ULN2003 family, but check V_sat and input thresholds.

Sourcing risklow

The ULN2003 is a widely multi-sourced part, providing many options.

Can it be replaced directly?

No drop-in replacement is guaranteed without datasheet review. However, other ULN2003A devices in SOP-16 packages are the most likely candidates.

Best replacement path

Cross-reference to other ULN2003A variants in a SOP-16 package.

Main risk

Package and pinout mismatches between different manufacturers' SO-16/SOP-16 footprints.

Recommended alternatives

Strong functional alternative from the ULN2003 family with a wider temperature range.
