Key Parameters

Substitute Part Grouping Explanation

Substitution of the RB155-BP is determined by the following critical electrical and mechanical parameters:

• Voltage - Peak Reverse (Max): 600 V minimum
• Current - Average Rectified (Io): 1.5 A minimum
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Package / Case: 4-Circular configuration

The W06G-E4/51 manufactured by Vishay General Semiconductor - Diodes Division meets all substitution criteria. Both components share identical peak reverse voltage (600 V) and average rectified current (1.5 A) ratings. Both employ standard single-phase bridge rectifier technology in through-hole 4-Circular packages. The W06G-E4/51 operates across an extended temperature range (-55°C to 150°C) compared to the RB155-BP, providing additional thermal margin in high-temperature applications.

Parameter Comparison

Engineering Selection Recommendations

The W06G-E4/51 is a direct functional substitute for the obsolete RB155-BP. Both components satisfy identical electrical specifications for voltage and current ratings and employ standard single-phase bridge rectifier technology. The W06G-E4/51 maintains active product status with established supply availability, whereas the RB155-BP is obsolete. Both components carry ROHS3 compliance and EAR99 export classification, ensuring regulatory alignment. The W06G-E4/51 provides an extended operating temperature range to 150°C, offering improved thermal performance in demanding environments. Through-hole mounting compatibility is maintained between both components, supporting direct board-level substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the W06G-E4/51 directly replace the RB155-BP in existing circuit designs?

A: Yes. Both components share identical peak reverse voltage (600 V) and average rectified current (1.5 A) ratings. Both employ standard single-phase bridge rectifier technology and through-hole mounting. The W06G-E4/51 is electrically and functionally equivalent for all specified parameters.

Q: What are the differences between the RB155-BP and W06G-E4/51?

A: The primary differences are product status and thermal operating range. The RB155-BP is obsolete; the W06G-E4/51 is active. The W06G-E4/51 operates to 150°C junction temperature compared to 125°C for the RB155-BP. The W06G-E4/51 exhibits lower reverse leakage current (5 µA versus 10 µA at 600 V). Package designations differ (RB-15 versus WOG), though both are 4-Circular through-hole configurations.

Q: Are there any compliance or certification differences?

A: No. Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Regulatory and compliance status is equivalent.

Q: What is the impact of the extended temperature range in the W06G-E4/51?

A: The W06G-E4/51 operates to 150°C junction temperature, providing 25°C additional thermal margin above the RB155-BP specification of 125°C. This extended range supports applications with elevated ambient temperatures or higher power dissipation without thermal derating.

Q: Are the through-hole packages mechanically compatible?

A: Both components employ 4-Circular through-hole packages suitable for PCB mounting. Physical package dimensions and lead configurations support direct board-level substitution without layout modifications.
