RM 2A Equivalent & Substitute Parts Reference

Part Overview

The RM 2A from Sanken Electric USA Inc. is an axial, through-hole general purpose diode rated at 600 V and 1.2 A. The product is classified as obsolete. Engineering teams often need to identify equivalent or substitute diodes based on electrical and mechanical compatibility when the primary component is no longer available or actively manufactured. Alternatives must be chosen based strictly on matching provided parameters to ensure correct electrical performance and physical fit.

Substitute Part Grouping Explanation

Substitute diodes are identified by matching the following essential parameters: component category (Diodes, Rectifiers), package/case style (axial, through-hole), maximum reverse voltage (600 V), average rectified current (≥1.2 A), forward voltage rating at specified current, speed classification, reverse leakage current at maximum VR, operating temperature range, RoHS compliance, and equivalent certifications. Only parts matching these criteria are considered appropriate substitutes.

Engineering Selection Recommendations

When replacing the RM 2A diode, selection is determined by product status (obsolete versus active) and confirmed RoHS compliance and certifications. All substitute parts listed—1N5397-E3/54, 1N6622, GP15J-E3/54, RGP15J-E3/54—are active products and are RoHS compliant with matching ECCN and HTSUS codes. These substitutes are suitable from an inventory, compliance, and certification perspective, in alignment with regulatory and environmental requirements.

Frequently Asked Questions (FAQ)

Q1: What are the main electrical parameters required to approve a diode substitute for RM 2A?
A1: Substitute approval requires matching the diode category, package/case style (axial, through-hole), maximum reverse voltage (600 V), average rectified current (≥1.2 A), forward voltage rating, speed classification, reverse leakage current at maximum VR, and identical operating temperature range.

Q2: Is it necessary for substitute parts to be RoHS compliant?
A2: Yes; the RM 2A is RoHS compliant, and substitutes must have equivalent RoHS compliance status.

Q3: Can different package/case sizes be accepted as substitutes?
A3: Only axial, through-hole packages/cases are acceptable to ensure direct mechanical and electrical compatibility.

Q4: What considerations should be made for operating temperature range?
A4: Substitute parts must support an equal or wider operating temperature junction range compared to the RM 2A (-40°C ~ 150°C).

Q5: Are moisture sensitivity and export control codes relevant for substitution?
A5: Yes; MSL must be 1 (Unlimited), and certifications such as ECCN EAR99 and HTSUS 8541.10.0080 must match the original part to maintain regulatory compliance.
