RL203-BP Equivalent & Substitute Parts Reference

Part Overview

RL203-BP is a standard recovery rectifier diode manufactured by Micro Commercial Co in the Diodes, Rectifiers category. It features 200 V maximum reverse voltage, 2A average rectified current, and is housed in a through-hole DO-15 (DO-204AC) axial package. RL203-BP is currently listed as Not For New Designs, indicating that identifying and selecting equivalent or substitute parts is necessary to ensure long-term availability and supply continuity in both new and legacy designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute and equivalent parts are determined exclusively by matching the following key parameters: voltage - DC reverse (Vr) (Max), current - average rectified (Io), voltage - forward (Vf) (Max), speed, current - reverse leakage @ Vr, capacitance @ Vr, mounting type, package/case, and operating temperature - junction. These parameters ensure electrical and mechanical compatibility within the Diodes, Rectifiers product category.

Parameter Comparison

Engineering Selection Recommendations

The RL203-BP part has a status of Not For New Designs. Substitute parts 1N5059GP-E3/54, PR1503-T, and SBYV27-200-E3/54 are all listed as Active and show ROHS3, REACH, and ECCN EAR99 compliance. Selection among these substitutes should be based on inventory position and compliance requirements. Only parameters explicitly provided have been considered.

Frequently Asked Questions (FAQ)

Q1: Which electrical parameters are critical for substituting RL203-BP in rectifier diode applications?
A1: The key electrical parameters are voltage - DC reverse (Vr) (Max), current - average rectified (Io), voltage - forward (Vf) (Max), speed, current - reverse leakage @ Vr, and capacitance @ Vr.

Q2: Do all substitute parts use the same package as RL203-BP?
A2: All listed substitutes are specified with the DO-204AC, DO-15, Axial package, consistent with RL203-BP.

Q3: Are there any differences in mounting type?
A3: All parts share the through-hole mounting type.

Q4: How does product compliance compare among RL203-BP and the substitutes?
A4: The substitutes 1N5059GP-E3/54, PR1503-T, and SBYV27-200-E3/54 are ROHS3 compliant and REACH unaffected with ECCN EAR99, as explicitly provided.

Q5: Is it necessary to consider forward voltage (Vf) differences in substitute diodes?
A5: Forward voltage (Vf) at a given current is a key substitution criterion. Comparison of Vf values is shown in the Parameter Comparison table. Substitution decisions must be based strictly on these provided values.
