RB154-BP Bridge Rectifier Single Phase 400V 1.5A Equivalent & Substitute Parts

Part Overview

The RB154-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 400V peak reverse voltage and 1.5A average rectified current. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations. The through-hole RB-15 package configuration and standard rectification technology establish the baseline for compatible alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RB154-BP is determined by the following critical parameters:

• Diode Type & Technology: Single phase, standard technology rectification
• Voltage Rating: 400V peak reverse voltage (Vrrm) minimum requirement
• Current Rating: 1.5A average rectified current (Io) minimum requirement
• Mounting Configuration: Through-hole assembly compatibility
• Package Form Factor: 4-circular pin configuration for mechanical fit
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The W04G-E4/51 meets all substitution criteria within these parameters. Both components share identical voltage and current ratings, equivalent forward voltage characteristics, and compatible through-hole mounting. The substitute part maintains regulatory compliance and offers improved availability as an active product.

Parameter Comparison

Engineering Selection Recommendations

The W04G-E4/51 serves as a direct functional substitute for the RB154-BP based on electrical parameter equivalence and regulatory compliance alignment. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications requiring environmental standards adherence.

The W04G-E4/51 offers operational advantages including lower reverse leakage current (5 µA versus 10 µA at 400V) and an extended operating temperature range (-55°C to 150°C versus -55°C to 125°C). These characteristics provide enhanced performance margins in thermal and leakage-sensitive applications.

The transition from the obsolete RB154-BP to the active W04G-E4/51 addresses supply chain continuity while maintaining electrical and mechanical compatibility through equivalent 400V/1.5A ratings and compatible 4-circular through-hole packaging.

Frequently Asked Questions (FAQ)

Q: Can the W04G-E4/51 directly replace the RB154-BP in existing designs?

A: Yes. Both components share identical voltage (400V) and current (1.5A) ratings, equivalent forward voltage characteristics, and compatible through-hole 4-circular pin configurations. The W04G-E4/51 meets all electrical and mechanical substitution criteria.

Q: What are the key differences between these parts?

A: The W04G-E4/51 features lower reverse leakage current (5 µA versus 10 µA) and an extended operating temperature range to 150°C. The RB154-BP is obsolete while the W04G-E4/51 is an active product with established supply availability.

Q: Are there package compatibility concerns?

A: Both components use 4-circular through-hole configurations. The RB-15 and WOG package designations refer to different manufacturer conventions but maintain compatible pin spacing and mounting footprints for standard through-hole PCB applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the RB154-BP and W04G-E4/51 are ROHS3 compliant and REACH unaffected, ensuring equivalent regulatory status for applications requiring environmental standards compliance.

Q: Which part should be selected for new designs?

A: The W04G-E4/51 is the appropriate selection for new designs. As an active product from an established manufacturer, it provides supply chain continuity, improved performance characteristics, and extended temperature range capability.
