RB151-BP Bridge Rectifier Single Phase 50V 1.5A Equivalent & Substitute Parts
Part Overview
The RB151-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 50V peak reverse voltage and 1.5A average rectified current. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. The through-hole RB-15 package configuration requires substitutes with identical mechanical and electrical compatibility.

Substitute Part Grouping Explanation
Substitution of the RB151-BP is determined by the following critical parameters:
- Voltage Rating: Peak reverse voltage must equal or exceed 50V
- Current Rating: Average rectified current must equal or exceed 1.5A
- Package Type: Must be 4-Circular through-hole configuration for mechanical compatibility
- Diode Configuration: Single-phase bridge rectifier topology
- Technology Class: Standard rectifier technology
- Compliance: RoHS3 compliance required for regulatory alignment
The W005G-E4/51 manufactured by Vishay General Semiconductor - Diodes Division satisfies all substitution criteria with matching electrical specifications and package configuration.

Engineering Selection Recommendations
The W005G-E4/51 is a direct functional equivalent for the obsolete RB151-BP. Both components meet identical electrical specifications for voltage and current ratings, operate within compatible temperature ranges, and maintain RoHS3 compliance. The W005G-E4/51 offers extended maximum operating temperature (150°C vs. 125°C) and lower reverse leakage current (5 µA vs. 10 µA), providing improved performance margins. Active product status ensures ongoing availability and supply chain continuity. Through-hole mounting compatibility is maintained across both 4-Circular package variants (RB-15 and WOG).
Frequently Asked Questions (FAQ)
Q: Can the W005G-E4/51 be used as a direct replacement for the RB151-BP?
A: Yes. Both components share identical peak reverse voltage (50V), average rectified current (1.5A), and single-phase bridge rectifier configuration. Through-hole 4-Circular package compatibility is maintained between RB-15 and WOG variants.
Q: What are the key differences between these parts?
A: The W005G-E4/51 has a higher maximum operating temperature (150°C vs. 125°C), lower reverse leakage current (5 µA vs. 10 µA), and active product status compared to the obsolete RB151-BP. Forward voltage specification differs at measurement current (1V @ 1A vs. 1V @ 1.5A).
Q: Are there package compatibility concerns?
A: Both parts use 4-Circular through-hole packages. The RB-15 and WOG package designations refer to the same physical form factor, ensuring mechanical and electrical compatibility on PCB layouts.
Q: Does the W005G-E4/51 meet the same compliance requirements?
A: Yes. Both components are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment for equivalent applications.
Q: Why is the RB151-BP obsolete?
A: The RB151-BP is classified as obsolete by the manufacturer. The W005G-E4/51 provides equivalent functionality with active product status and improved performance characteristics.
