Before you substitute

A match is the beginning.
The details make the difference.

Use the manufacturer’s datasheets and your application requirements to evaluate each candidate.

01

Package & pinout

Compare dimensions, mounting style and every pin assignment. A matching package alone does not establish compatibility.

02

Electrical limits

Review supply range, voltage and current ratings, power dissipation and the operating conditions behind each specification.

03

Function & performance

Check timing, accuracy, bandwidth and application-specific behavior against your circuit requirements.

04

Temperature & qualification

Confirm the operating temperature range, required qualifications and reliability needs for your application.

Understand the relationship

Related doesn’t always
mean replaceable.

Each relationship gives you a different starting point for evaluation.

Cross-reference candidates
Parts linked by a cross-reference record. Compare specifications and validate suitability for your circuit.
Generic / functional groups
Parts grouped by a common family or function. Individual variants can differ in package, ratings and behavior.
Complementary parts
Devices with a paired or supporting role. These relationships do not imply interchangeability.

A few useful answers

Before you choose.

How are alternative candidates found?

Voltkit uses catalog cross-reference and component relationship records to surface candidates. Search by part number, then review the available source and candidate details side by side.

Can I use a cross-reference part as a direct replacement?

A cross-reference is a starting point for evaluation. Confirm the pinout, electrical specifications and application requirements in the manufacturers’ datasheets, then validate the part in your design before approving a replacement.

Why are some parameters missing?

Not every catalog record includes every specification. “Not available” means that field is missing from the available record; it does not mean the two parts have the same specification. Refer to the manufacturer’s datasheet for confirmation.

What should I do if my part has no matches?

Check the spelling and try a shorter part-number prefix. You can also request a quote with the exact model and describe the package, quantity and requirements you need.

Are complementary parts also substitutes?

No. Complementary parts are related devices intended for a different or paired role. Their relationship does not imply that they are interchangeable.
