PBPC602 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The PBPC602 is a single-phase bridge rectifier manufactured by Diodes Incorporated, rated for 100 V peak reverse voltage and 4 A average rectified current in a through-hole PBPC-6 package. The product is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating package and mounting requirements.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Electrical Compatibility Requirements:

Voltage - Peak Reverse (Max): Must equal or exceed 100 V
Current - Average Rectified (Io): Must equal or exceed 4 A
Voltage - Forward (Vf) (Max) @ If: Must not exceed 1.1 V @ 3 A
Current - Reverse Leakage @ Vr: Must not exceed 10 µA @ 100 V
Operating Temperature Range: Must encompass or exceed -65°C ~ 125°C

Mechanical Compatibility Requirements:

Mounting Type: Through Hole (required)
Package / Case: 4-Square configuration (required)
Diode Type: Single Phase (required)
Technology: Standard (required)

Both substitute parts meet these criteria and are electrically and mechanically compatible with the PBPC602.

Engineering Selection Recommendations

BR61 (GeneSiC Semiconductor) is the primary substitute for new applications. It maintains 100 V peak reverse voltage and identical thermal specifications while providing 6 A average rectified current capacity. The part is in active production status with RoHS compliance certification. Forward voltage is 1 V @ 3 A, which is lower than the PBPC602 specification, resulting in reduced power dissipation. This part is suitable for direct replacement in existing designs and recommended for new production.

PB61-BP (Micro Commercial Co) is an alternative substitute with equivalent electrical performance to the PBPC602. It provides 6 A average rectified current and maintains the same forward voltage specification of 1.1 V @ 3 A. The operating temperature range extends to 150°C maximum, exceeding the PBPC602 specification. However, the product status is classified as "Not For New Designs," limiting its application to legacy system maintenance and repair. ROHS3 compliance is maintained.

Both substitutes are mechanically compatible through-hole devices in 4-square package configurations. Selection between BR61 and PB61-BP depends on production status requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can BR61 directly replace PBPC602 in existing circuits? A: Yes. BR61 meets all electrical requirements with equal or superior specifications. The 100 V peak reverse voltage, identical thermal range, and through-hole mounting are compatible. The higher current rating (6 A vs 4 A) and lower forward voltage provide operational margin.

Q: What is the difference between BR61 and PB61-BP? A: Both parts meet PBPC602 electrical specifications. BR61 is in active production with lower forward voltage (1 V vs 1.1 V). PB61-BP is classified as "Not For New Designs" but has an extended maximum operating temperature of 150°C. For new production, BR61 is preferred.

Q: Are the package dimensions identical between PBPC-6, BR-6, and PB-6? A: All three parts use 4-square through-hole package configurations. Physical dimensions are compatible for PCB mounting. Verify specific package drawings with manufacturers for critical applications.

Q: What is the minimum current rating required for substitution? A: Substitute parts must support at least 4 A average rectified current. Both BR61 and PB61-BP exceed this requirement at 6 A, providing design margin.

Q: Are there compliance differences between the substitutes? A: BR61 carries RoHS compliance certification. PB61-BP carries ROHS3 compliance. Both meet regulatory requirements for their respective markets. PBPC602 is ROHS3 compliant.

Q: Can PB61-BP be used in new designs? A: PB61-BP is classified as "Not For New Designs." It is suitable for maintenance, repair, and legacy system support only. BR61 is the recommended choice for new production.
