Equivalent & Substitute Parts for RU 3AMV Diode

Part Overview

The Sanken Electric USA Inc. RU 3AMV is a general-purpose, fast recovery diode in the Diodes, Rectifiers category. It features a reverse voltage rating of 600 V and a forward current rating of 1.5 A, housed in an axial through-hole package. This part is currently listed as obsolete, making it necessary to identify alternative models with matching electrical and mechanical characteristics for ongoing designs or repairs that require this specification.

Substitute Part Grouping Explanation

Suitable substitute parts must exactly match the following key electrical and mechanical parameters to ensure proper function and form compatibility:

Voltage - DC Reverse (Vr) (Max)
Current - Average Rectified (Io)
Voltage - Forward (Vf) (Max) @ If
Speed classification and reverse recovery time (trr)
Current - Reverse Leakage @ Vr
Mounting Type and Package / Case
Operating Temperature - Junction
Compliance and environmental ratings (RoHS, MSL)

Parts matching all these parameters are considered equivalent substitutes within this component category.

Engineering Selection Recommendations

Selection of the RU 3AMV1 as a substitute for RU 3AMV is justified based on equivalent electrical and mechanical parameters, identical environmental compliance (RoHS status), and matching moisture sensitivity level (MSL). Both parts are obsolete and share the same operating temperature range and physical package.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria to substitute the RU 3AMV diode?
A1: Substitution requires exact matching of maximum reverse voltage, average forward current, forward voltage at the rated current, reverse recovery time, reverse leakage current, mounting type, package, operating temperature, and compliance parameters.

Q2: Are the RU 3AMV and RU 3AMV1 fully interchangeable in terms of function and footprint?
A2: Both diodes share matching specifications and axial through-hole packages. The only difference is packaging format (Tape & Reel vs. Cut Tape), which does not affect board-level compatibility.

Q3: If both parts are obsolete, can RU 3AMV1 still serve as an interim replacement?
A3: RU 3AMV1 can serve as a direct substitute for existing inventory needs due to identical parameter sets and compliance attributes.

Q4: Does the packaging type (TR vs. CT) impact electrical or mechanical performance?
A4: Packaging type only affects delivery and storage. It does not influence installed component performance or board compatibility.

Q5: What compliance statuses are provided?
A5: Both RU 3AMV and RU 3AMV1 are RoHS Compliant with a Moisture Sensitivity Level (MSL) of 1 (Unlimited).
