Engineering Selection Recommendations

AL01V is classified as "Obsolete"; all substitute parts (EU 2V, EU02V, EU02V1) are "Active" and RoHS Compliant with an unlimited moisture sensitivity level. According to the provided substitute list, these alternatives match the required category, package, electrical, and compliance parameters.

Frequently Asked Questions (FAQ)

Q1: What parameters determine whether a diode is a valid substitute for AL01V?
A1: Valid substitutes for AL01V require the same maximum DC reverse voltage (400 V), average rectified current (1A), forward voltage (1.4 V @ 1A), reverse recovery time classification (fast recovery), reverse leakage current (10 µA @ 400 V), identical mounting type (through hole), and axial package.

Q2: Are the listed substitute diodes compliant with RoHS requirements?
A2: All substitute parts (EU 2V, EU02V, EU02V1) are RoHS Compliant.

Q3: Does the packaging type impact interchangeability?
A3: All substitutes retain the axial through-hole format, supporting direct replacement. Variations in tape or cut tape packaging do not affect installation within the specified mounting type.

Q4: Why is reverse recovery time noted in substitution considerations?
A4: Reverse recovery time is an essential performance parameter for fast recovery diodes. All substitutes are classified within the fast recovery category with times ≤ 500 ns.

Q5: What is the moisture sensitivity level for all listed diodes?
A5: All listed parts have an MSL of 1 (Unlimited), permitting unrestricted handling and mounting in typical through-hole applications.

Q6: How is product status relevant in selection?
A6: As AL01V is obsolete, only active substitutes are recommended per the provided product status information.
