PBPC604 Bridge Rectifier Single Phase 400V 4A Equivalent & Substitute Parts

Part Overview

The PBPC604 is a single-phase bridge rectifier manufactured by Diodes Incorporated, rated for 400V peak reverse voltage and 4A average rectified current in a through-hole PBPC-6 package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new procurement strategies. The part operates across a temperature range of -65°C to 125°C and complies with RoHS3 and REACH regulations.

Substitute Part Grouping Explanation

Substitution for the PBPC604 is determined by electrical and mechanical compatibility across the following critical parameters:

Voltage - Peak Reverse (Max): Must equal or exceed 400 V
Diode Type: Must be Single Phase
Technology: Must be Standard
Mounting Type: Must be Through Hole
Package / Case: Must be 4-Square configuration
Current - Average Rectified (Io): Must meet or exceed 4 A minimum requirement
Operating Temperature Range: Must encompass or exceed the specified range
Moisture Sensitivity Level: Must be MSL 1 or equivalent

The substitute parts BR64 and PB64-BP meet these electrical and mechanical criteria, with current ratings of 6 A, providing operational margin above the 4 A requirement of the PBPC604.

Engineering Selection Recommendations

BR64 (GeneSiC Semiconductor) is the primary substitute for PBPC604. This part maintains identical electrical specifications for voltage and temperature range, carries Active product status ensuring long-term availability, and holds RoHS compliance certification. The 6 A current rating provides operational margin above the 4 A requirement.

PB64-BP (Micro Commercial Co) serves as a secondary substitute option. While electrically compatible with identical voltage and current specifications, this part carries a "Not For New Designs" status, limiting its suitability for new applications. The extended operating temperature range of -55°C to 150°C exceeds PBPC604 specifications. RoHS3 compliance is maintained.

For applications requiring the PBPC604, BR64 is the recommended substitute due to active product status and assured supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can BR64 directly replace PBPC604 in existing designs? A: Yes. BR64 meets all electrical and mechanical compatibility criteria. The identical 400 V peak reverse voltage, matching operating temperature range, through-hole mounting, and 4-Square package configuration enable direct substitution. The 6 A current rating exceeds the 4 A requirement.

Q: What is the difference between BR-6 and PBPC-6 packages? A: Both are 4-Square through-hole packages for single-phase bridge rectifiers. Physical dimensions and pin configurations are equivalent for this product category, enabling mechanical interchangeability.

Q: Why is PB64-BP marked "Not For New Designs"? A: This designation indicates the manufacturer has discontinued active development and support for this part. While electrically compatible, it is not recommended for new circuit designs due to uncertain long-term availability.

Q: Are there temperature range differences between substitutes? A: PBPC604 and BR64 share identical operating ranges of -65°C to 125°C. PB64-BP extends to -55°C to 150°C, providing wider temperature coverage but with reduced low-temperature performance at -65°C.

Q: Do all substitute parts maintain RoHS compliance? A: Yes. PBPC604 and PB64-BP are RoHS3 compliant. BR64 is RoHS compliant. All parts meet environmental regulatory requirements for their respective certifications.

Q: What is the forward voltage difference between substitutes? A: BR64 specifies 1 V @ 3 A, while PBPC604 and PB64-BP both specify 1.1 V @ 3 A. This 0.1 V difference is within standard rectifier tolerance and does not affect circuit functionality.
