PBPC805 Bridge Rectifier Single Phase 600V 6A Equivalent & Substitute Parts

Part Overview

The PBPC805 is a single-phase bridge rectifier manufactured by Diodes Incorporated, rated for 600V peak reverse voltage and 6A average rectified current. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The PBPC805 features a through-hole PBPC-8 package configuration and operates across a temperature range of -65°C to 125°C.

Substitute Part Grouping Explanation

Substitution of the PBPC805 is determined by strict equivalence across the following electrical and mechanical parameters:

Voltage - Peak Reverse (Max): 600 V minimum
Diode Type: Single Phase
Technology: Standard
Mounting Type: Through Hole
Package Configuration: 4-Square form factor
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 4 A or lower
Current - Reverse Leakage @ Vr: 10 µA @ 600 V or lower

The PB86-BP from Micro Commercial Co meets these substitution criteria. While the PB86-BP supports a higher average rectified current rating of 8A (compared to 6A for the PBPC805), this represents a functional upgrade that maintains full backward compatibility. The electrical characteristics, voltage ratings, and package form factor are equivalent.

Engineering Selection Recommendations

The PB86-BP is a direct functional substitute for the PBPC805. Selection should be based on the following factors:

Product Status: The PBPC805 is obsolete, while the PB86-BP is active and currently in production. This makes the PB86-BP the preferred choice for new designs and ongoing procurement.

Compliance & Certifications: Both parts carry equivalent regulatory compliance. The PBPC805 is ROHS3 Compliant and REACH Affected. The PB86-BP is REACH Unaffected. Both are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Current Rating: The PB86-BP provides an 8A average rectified current rating versus the PBPC805's 6A rating. This higher rating does not compromise compatibility and provides additional design margin for applications requiring the original 6A specification.

Temperature Range: The PBPC805 operates from -65°C to 125°C, while the PB86-BP operates from -55°C to 125°C. Applications requiring operation below -55°C must retain the PBPC805 or identify alternative solutions.

Package Consideration: While both use 4-Square through-hole packages, the PBPC805 uses PBPC-8 and the PB86-BP uses PB-10. Physical dimensions should be verified for PCB layout compatibility, though both are standard 4-Square configurations.

Frequently Asked Questions (FAQ)

Q: Can the PB86-BP replace the PBPC805 in existing designs?

A: Yes. The PB86-BP meets all electrical substitution criteria for the PBPC805, including voltage ratings, forward voltage characteristics, and reverse leakage specifications. Physical package verification is required to confirm PCB layout compatibility.

Q: What is the difference between the PBPC-8 and PB-10 packages?

A: Both are 4-Square through-hole package configurations. The PBPC-8 and PB-10 designations refer to manufacturer-specific package variants. While electrically equivalent, physical dimensions and lead spacing should be confirmed against PCB footprints before implementation.

Q: Why is the PB86-BP rated for 8A when the PBPC805 is rated for 6A?

A: The PB86-BP represents a higher-performance variant of the same bridge rectifier topology. The increased current rating provides additional thermal and electrical margin without affecting compatibility with applications designed for 6A operation.

Q: Are there compliance differences between the PBPC805 and PB86-BP?

A: Both parts carry equivalent regulatory classifications (ECCN EAR99, HTSUS 8541.10.0080). The PBPC805 is ROHS3 Compliant and REACH Affected, while the PB86-BP is REACH Unaffected. Compliance requirements for specific applications should be verified against procurement specifications.

Q: What is the operating temperature consideration for substitution?

A: The PBPC805 operates from -65°C to 125°C, while the PB86-BP operates from -55°C to 125°C. Applications requiring operation below -55°C must use the PBPC805 or identify alternative solutions with extended low-temperature ratings.

Q: Is the PB86-BP currently available?

A: Yes. The PB86-BP is classified as Active product status with 877 pieces in stock. The PBPC805 is obsolete with limited remaining inventory of 929 pieces.
