RO 2BV Equivalent & Substitute Parts Reference

Part Overview

The Sanken Electric USA Inc. RO 2BV is an active, general-purpose rectifier diode in the Diodes, Rectifiers category. It is designed for through-hole mounting in an axial package with maximum ratings of 800 V DC reverse voltage and 1.2A average rectified current. Engineers may require alternative models for the RO 2BV due to inventory levels, packaging preferences, manufacturing continuity, or supplier allocation.

Substitute Part Grouping Explanation

Substitution is based strictly on the match of key parameters critical to the category Diodes, Rectifiers. Acceptable substitutes must provide:

Maximum DC reverse voltage of 800 V
Average rectified current of 1.2A
Maximum forward voltage not exceeding original specification at the specified current
Standard recovery speed category
Reverse leakage current no greater than specified value at maximum reverse voltage
Through-hole mounting and axial package
Identical or wider operating junction temperature range
Equivalent RoHS status and MSL for compliance consistency

Engineering Selection Recommendations

All listed parts including RO 2BV, EM 2BV1, and SARS01V1 are active and maintain consistent RoHS compliance along with a Moisture Sensitivity Level (MSL) rating of 1 (Unlimited). These selections meet identical regulatory and status requirements and are suitable for applications specifying compliance or inventory management as a primary criterion.

Frequently Asked Questions (FAQ)

Q1: What determines whether EM 2BV1 and SARS01V1 can be used as substitutes for RO 2BV?
A1: All critical electrical and mechanical parameters, including maximum reverse voltage, rectified current, forward voltage, leakage, speed class, package, and mounting type, must match the original RO 2BV specification.

Q2: Is the axial package and through-hole mounting maintained across all substitutes?
A2: Yes, RO 2BV, EM 2BV1, and SARS01V1 all use an axial package for through-hole mounting.

Q3: Are there any differences in RoHS or MSL status among the listed substitutes?
A3: No, all parts are RoHS Compliant and rated MSL 1 (Unlimited).

Q4: Does the voltage or current rating differ among these models?
A4: The voltage and current ratings are identical for all parts listed in this reference.

Q5: Can the listed substitutes be used interchangeably in all assemblies originally designed for RO 2BV, based strictly on these parameters?
A5: All provided parameters support direct interchangeability within assemblies designed for RO 2BV.
