CBR1-010 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The CBR1-010 is a single-phase bridge rectifier manufactured by Central Semiconductor Corp, rated for 100 V peak reverse voltage and 1.5 A average rectified current. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The through-hole A Case package and standard rectification technology establish the baseline for equivalent part selection.

Substitute Part Grouping Explanation

Substitute parts for the CBR1-010 are identified based on electrical and mechanical parameter equivalence. The critical substitution criteria are:

• Single-phase bridge rectifier topology
• 100 V peak reverse voltage rating
• 1.5 A average rectified current capacity
• Through-hole mounting configuration
• 4-circular package form factor
• Standard rectification technology

The W01G-E4/51 manufactured by Vishay General Semiconductor - Diodes Division meets all primary electrical specifications and maintains through-hole mounting compatibility. Package designation differs (WOG versus A Case), but both are 4-circular through-hole configurations suitable for equivalent circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

The W01G-E4/51 is the primary substitute for the obsolete CBR1-010. Both components share identical electrical ratings for voltage and current specifications, ensuring functional equivalence in rectification applications. The W01G-E4/51 maintains active product status with ROHS3 compliance, supporting modern procurement and environmental regulatory requirements.

The reverse leakage current of the W01G-E4/51 (5 µA @ 100 V) is lower than the CBR1-010 (10 µA @ 100 V), representing improved performance characteristics. The operating temperature minimum of the W01G-E4/51 (-55°C) is higher than the CBR1-010 (-65°C); applications requiring operation below -55°C require design review.

Both components utilize 4-circular through-hole package configurations compatible with standard PCB mounting practices. Physical footprint verification against original design documentation is necessary prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the W01G-E4/51 directly replace the CBR1-010 in existing designs?

A: The W01G-E4/51 meets all primary electrical specifications (100 V, 1.5 A, single-phase bridge rectifier). Physical package compatibility requires verification of PCB footprint dimensions and lead spacing between the A Case and WOG packages.

Q: What is the significance of the lower reverse leakage current in the W01G-E4/51?

A: The W01G-E4/51 exhibits 5 µA reverse leakage compared to 10 µA in the CBR1-010. This represents improved leakage performance and may provide benefits in high-impedance circuit applications, though both values are within standard rectifier specifications.

Q: Are there temperature range considerations for substitution?

A: The W01G-E4/51 operates from -55°C to 150°C, while the CBR1-010 operates from -65°C to 150°C. Applications requiring operation below -55°C must retain the original CBR1-010 specification or identify alternative components with extended low-temperature ratings.

Q: What does ROHS3 compliance mean for the W01G-E4/51?

A: ROHS3 compliance indicates the component meets Restriction of Hazardous Substances Directive requirements, restricting specified hazardous materials. This supports compliance with modern environmental and procurement standards.

Q: How do the package designations (A Case vs. WOG) affect substitution?

A: Both A Case and WOG are 4-circular through-hole package types. Physical dimensions and lead configurations may differ; PCB layout verification is required to confirm mechanical compatibility before component substitution.
