- Product type
- Operational Amplifier
- Package
- SOT-23-5
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.
Package & pinout
Compare dimensions, mounting style and every pin assignment. A matching package alone does not establish compatibility.
Electrical limits
Review supply range, voltage and current ratings, power dissipation and the operating conditions behind each specification.
Function & performance
Check timing, accuracy, bandwidth and application-specific behavior against your circuit requirements.
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.
