UES1301 Equivalent & Substitute Parts Reference

Part Overview

Microchip Technology UES1301 is a standard recovery diode in the diodes, rectifiers category, featuring 50 V reverse voltage, 6A average rectified current, and a fast recovery time (trr) of 30 ns in a B, axial through-hole package. It is currently classified as Active, though it is not RoHS compliant. Finding alternative models may be necessary when compliance with environmental regulations is required, for optimizing supply chains, or if variation in electrical or mechanical parameters is permissible within a given application.

Key Parameters

Substitute Part Grouping Explanation

Substitute relationships are established by direct comparison of the following parameters: voltage - DC reverse (Vr) (max), current - average rectified (Io), voltage - forward (Vf) (max) at specified current, speed classification and reverse recovery time (trr), mounting type, package/case, and RoHS compliance status. Only parts that share these critical specifications or are within acceptable tolerances are listed, as all data strictly derives from the parameters explicitly provided.

Parameter Comparison

Engineering Selection Recommendations

Selection should consider product status and compliance designations. UES1301 is Active but RoHS non-compliant, whereas STTH302 is Active and ROHS3 Compliant. For requirements involving RoHS compliance, STTH302 satisfies this criterion. Both parts are in the same product category and have an Active status.

Frequently Asked Questions (FAQ)

Q1: What are the main substitution criteria between UES1301 and STTH302?
A1: Main substitution criteria are voltage - DC reverse (Vr) (Max), current - average rectified (Io), voltage - forward (Vf) (Max) at specified current, speed classification, reverse recovery time (trr), mounting type, package/case, operating temperature range, and RoHS status.

Q2: Can the STTH302 directly replace the UES1301 in all cases?
A2: Substitution is based strictly on provided parameters. Mechanical compatibility and compliance requirements should be evaluated in the application context since package/case and electrical ratings differ.

Q3: How do package differences impact selection?
A3: UES1301 uses a B, Axial package, while STTH302 uses DO-201AD, Axial. Mounting type is Through Hole for both, but physical dimensions may differ as per exact package designations.

Q4: Why is RoHS status important in selection?
A4: RoHS status impacts whether a part can be used in applications requiring restriction of hazardous substances. UES1301 is RoHS non-compliant; STTH302 is ROHS3 Compliant.

Q5: Is reverse recovery time (trr) comparable between both parts?
A5: UES1301 has a reverse recovery time (trr) of 30 ns, and STTH302 has 35 ns, both categorized as fast recovery.
