Equivalent & Substitute Parts for PBPC603

Part Overview

The PBPC603 is a single-phase bridge rectifier manufactured by Diodes Incorporated, rated for 200 V peak reverse voltage and 4 A average rectified current. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The PBPC603 features a 4-square PBPC-6 through-hole package and operates across a temperature range of -65°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PBPC603 is determined by the following critical parameters:

• Voltage - Peak Reverse (Max): 200 V minimum
• Diode Type: Single Phase
• Mounting Type: Through Hole
• Package / Case: 4-Square configuration
• RoHS Status: ROHS3 Compliant

Substitute parts must maintain electrical compatibility at the specified voltage and current ratings while preserving the through-hole mounting configuration. Current ratings may exceed the original specification without compromising functionality. Forward voltage and reverse leakage characteristics must remain within acceptable industrial tolerances for bridge rectifier applications.

Parameter Comparison

Engineering Selection Recommendations

BR62 (GeneSiC Semiconductor) is the primary substitute for the PBPC603. This part maintains identical voltage and temperature specifications while providing increased current capacity at 6 A. The BR62 carries active product status, ensuring continued availability and manufacturing support. All RoHS3 compliance requirements are met.

PB62-BP (Micro Commercial Co) serves as a secondary substitute option. This part matches the forward voltage characteristic of the original PBPC603 and provides the same 6 A current rating. However, PB62-BP is classified as "Not For New Designs," limiting its suitability for new applications. The extended operating temperature range of -55°C to 150°C provides additional thermal margin in specific environments.

Both substitute parts are electrically and mechanically compatible with the PBPC603 within the specified parameter tolerances and maintain through-hole mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can BR62 directly replace PBPC603 in existing circuits?

A: Yes. BR62 maintains the same 200 V peak reverse voltage rating and through-hole package configuration. The increased current rating of 6 A versus 4 A does not create compatibility issues in applications designed for the original 4 A specification.

Q: What is the difference between BR62 and PB62-BP?

A: Both parts provide 6 A current capacity and 200 V voltage rating. BR62 is actively manufactured by GeneSiC Semiconductor, while PB62-BP is designated "Not For New Designs" by Micro Commercial Co. BR62 is the recommended choice for new applications.

Q: Are the package dimensions identical across all three parts?

A: All three parts use 4-square through-hole packages (PBPC-6, BR-6, and PB-6 respectively). Physical compatibility is maintained for PCB mounting applications.

Q: What are the RoHS compliance implications?

A: All three parts are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Does the forward voltage difference between BR62 and PBPC603 affect circuit performance?

A: BR62 exhibits a lower forward voltage (1 V @ 3 A) compared to PBPC603 (1.1 V @ 3 A). This 0.1 V difference results in slightly reduced power dissipation in BR62, which is beneficial for thermal management in most applications.
