CBR1-100 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The CBR1-100 is a single-phase bridge rectifier rated for 1 kV peak reverse voltage and 1.5 A average rectified current, packaged in a 4-Circular A Case through-hole configuration. This part is currently listed as obsolete, making identification of functional equivalents necessary for ongoing system support and component procurement. Active alternatives with identical or superior electrical characteristics are available from multiple manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CBR1-100 is determined by the following critical parameters:

• Diode Type: Single Phase (required match)
• Voltage - Peak Reverse (Max): 1 kV (required match or higher)
• Current - Average Rectified (Io): 1.5 A (required match or higher)
• Mounting Type: Through Hole (required match)
• Package compatibility: Physical form factor must accommodate circuit board layout

The CBR1-100 TIN/LEAD variant meets all electrical and mechanical requirements as a parametric equivalent. The W10G-E4/51 from Vishay meets all critical electrical parameters and mounting requirements, with a different package designation (WOG vs. A Case) that maintains mechanical compatibility in through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete CBR1-100, the CBR1-100 TIN/LEAD is the direct replacement, offering identical electrical specifications and package configuration with active product status and ROHS3 compliance.

The W10G-E4/51 serves as a secondary alternative when CBR1-100 TIN/LEAD availability is constrained. This part meets all critical electrical parameters with superior reverse leakage characteristics (5 µA vs. 10 µA @ 1000 V). The WOG package maintains mechanical compatibility in standard through-hole applications. The operating temperature minimum of -55°C (versus -65°C for the CBR1-100) should be evaluated against application requirements.

Both substitute parts carry ROHS3 compliance and REACH unaffected status, supporting modern procurement and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the CBR1-100 TIN/LEAD be used as a direct replacement for the CBR1-100?

A: Yes. The CBR1-100 TIN/LEAD is electrically and mechanically identical to the CBR1-100, with matching voltage, current, and temperature specifications. The primary difference is product status: CBR1-100 TIN/LEAD is active and readily available.

Q: What is the difference between the A Case and WOG packages?

A: Both are 4-Circular through-hole packages designed for standard PCB mounting. The designations reflect different manufacturer package naming conventions. Both maintain mechanical compatibility in applications designed for through-hole bridge rectifiers with these electrical ratings.

Q: Is the W10G-E4/51 suitable for applications requiring the full -65°C to 150°C temperature range?

A: The W10G-E4/51 operates from -55°C to 150°C. Applications requiring operation below -55°C must use the CBR1-100 or CBR1-100 TIN/LEAD. For applications within the -55°C to 150°C range, the W10G-E4/51 is suitable.

Q: Does the lower reverse leakage of the W10G-E4/51 affect circuit performance?

A: The W10G-E4/51 exhibits 5 µA reverse leakage compared to 10 µA for the CBR1-100. Lower reverse leakage is a performance advantage and does not create compatibility issues in circuits designed for the CBR1-100.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the CBR1-100 TIN/LEAD and W10G-E4/51 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
