Key Parameters

Substitute Part Grouping Explanation

Substitute selection is based strictly on matching the main part’s core parameters: reverse DC voltage rating, average rectified current, mounting type, package/case, reverse leakage current, forward voltage, speed classification, RoHS compliance, MSL, ECCN, and operating temperature range. Only parts that fulfill all these conditions and match the required mechanical form factor are eligible as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The RM 10 diode is obsolete; its substitute, EM2 by Sanken Electric USA Inc., is active, offers identical electrical ratings, and maintains RoHS compliance and identical form factor. Vishay's 1N5395-E3/73 also meets voltage, current, mounting, compliance, and regulatory standards relevant for substitution in applications requiring original RM 10 performance parameters.

Frequently Asked Questions (FAQ)

Q1: What criteria must a diode meet to substitute for RM 10?
A: Substitute diodes must match the maximum reverse DC voltage, average rectified current, mounting type (through hole, axial), reverse leakage current, speed classification, operating temperature range, compliance certifications, and regulatory codes.

Q2: Are package and mounting type critical for substitution?
A: Yes. Both substitutes, EM2 and 1N5395-E3/73, provide axial through-hole mounting compatible with RM 10’s mechanical footprint.

Q3: Is RoHS compliance required for replacement diodes?
A: Yes. RM 10 and its substitutes list RoHS compliance status and moisture sensitivity level as required parameters for selection.

Q4: Does speed classification affect substitution?
A: All listed parts are standard recovery (>500ns, >200mA Io), consistent with RM 10's classification.

Q5: What is the key consideration when selecting between EM2 and 1N5395-E3/73?
A: Selection is determined by matching electrical ratings, mechanical form factor, and certification parameters. Both substitutes meet the required criteria for RM 10 replacement.
