CBR2-010 Equivalent & Substitute Parts

Part Overview

The CBR2-010 is a single-phase bridge rectifier manufactured by Central Semiconductor Corp, rated for 100 V peak reverse voltage and 2 A average rectified current. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The CBR2-010 features a through-hole A Case package suitable for standard rectification applications requiring moderate current handling in the 100 V range.

Substitute Part Grouping Explanation

Substitution of the CBR2-010 is determined by strict equivalence across the following electrical and mechanical parameters:

Diode Type: Single Phase bridge rectifier configuration
Voltage Rating: 100 V peak reverse voltage (Vrrm)
Current Rating: 2 A average rectified current (Io)
Forward Voltage: 1.1 V maximum at 2 A
Mounting: Through-hole technology
Package Form Factor: 4-Circular configuration

The 2W01G-E4/51 manufactured by Vishay General Semiconductor - Diodes Division meets all substitution criteria. This part maintains electrical equivalence across voltage, current, and forward voltage specifications while providing active product status and improved availability compared to the obsolete CBR2-010.

Engineering Selection Recommendations

The 2W01G-E4/51 is the direct substitute for the obsolete CBR2-010. Selection is based on the following factors:

All critical electrical parameters match or exceed CBR2-010 specifications
Active product status ensures long-term availability and supply chain continuity
ROHS3 compliance provides regulatory advantage for new designs and procurement
Reverse leakage current of 5 µA is lower than the CBR2-010 specification of 10 µA, indicating improved device quality
Operating temperature range of -55°C to 150°C covers the majority of standard industrial applications; designs requiring the full -65°C lower limit of the CBR2-010 require verification of actual application requirements
Through-hole mounting and 4-Circular package form factor ensure mechanical compatibility with existing PCB layouts

Frequently Asked Questions (FAQ)

Q: Can the 2W01G-E4/51 be used as a direct replacement for the CBR2-010 in existing designs?

A: Yes. The 2W01G-E4/51 meets all electrical specifications of the CBR2-010 and maintains the same through-hole 4-Circular package form factor. PCB layout compatibility is maintained without modification.

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

A: Both designations refer to the same 4-Circular through-hole form factor. A Case and WOG are manufacturer-specific package naming conventions for identical physical configurations. No functional or dimensional differences exist between these designations.

Q: Does the narrower operating temperature range of the 2W01G-E4/51 (-55°C to 150°C versus -65°C to 150°C) affect compatibility?

A: The 2W01G-E4/51 operates across the standard industrial temperature range. Applications requiring operation below -55°C must verify actual system requirements against the CBR2-010 specification before substitution.

Q: What is the significance of the lower reverse leakage current in the 2W01G-E4/51?

A: The 2W01G-E4/51 exhibits 5 µA reverse leakage at 100 V compared to 10 µA for the CBR2-010. Lower leakage current indicates improved device characteristics and is compatible with all applications designed for the CBR2-010.

Q: Is the 2W01G-E4/51 RoHS compliant?

A: Yes. The 2W01G-E4/51 is ROHS3 compliant. The CBR2-010 RoHS status is not specified in available documentation.
