PB64 Bridge Rectifier Single Phase 400V 6A Equivalent & Substitute Parts

Part Overview

The PB64 is a single-phase bridge rectifier rated for 400V peak reverse voltage with 6A average rectified current, housed in a 4-Square PB-6 through-hole package. This component is classified as obsolete, making identification of compatible substitutes essential for ongoing system maintenance and repair applications. The electrical and mechanical specifications of the PB64 establish the baseline criteria for determining functional equivalence with alternative part numbers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PB64 is determined by strict equivalence across the following critical parameters:

• Diode Type & Technology: Single Phase, Standard technology
• Voltage Rating: 400V peak reverse voltage (Vr)
• Current Rating: 6A average rectified current (Io)
• Forward Voltage Characteristics: 1.1V maximum at 3A
• Reverse Leakage: 10µA at 400V
• Temperature Range: -55°C to 150°C junction temperature
• Package Compatibility: 4-Square PB-6 through-hole configuration

The PB64-BP meets all electrical specifications identically to the main part number. The primary distinction is packaging format (bulk versus standard) and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The PB64-BP provides complete electrical and mechanical compatibility with the PB64. All critical rectification parameters—voltage rating, current capacity, forward voltage drop, reverse leakage, and temperature range—are identical. Both components utilize the same 4-Square PB-6 through-hole package, ensuring direct mechanical substitution without PCB layout modification.

The PB64-BP carries ROHS3 compliance status, whereas the original PB64 is RoHS non-compliant. This distinction is relevant for applications subject to regulatory compliance requirements. The PB64-BP is classified as "Not For New Designs," indicating it remains available for legacy system support and repair but is not recommended for new product development.

Selection between these parts should be based on compliance requirements and inventory availability rather than electrical performance, as both components deliver identical functional characteristics.

Frequently Asked Questions (FAQ)

Q: Can PB64-BP directly replace PB64 in existing circuits?

A: Yes. The PB64-BP is electrically and mechanically identical to the PB64 across all specified parameters. Direct substitution is possible without circuit modification.

Q: What is the difference between PB64 and PB64-BP?

A: The primary differences are packaging format (bulk versus standard) and compliance status. The PB64-BP is ROHS3 compliant, while the PB64 is not. Electrical specifications are identical.

Q: Does the through-hole PB-6 package remain the same for both parts?

A: Yes. Both the PB64 and PB64-BP use the 4-Square PB-6 through-hole package. PCB footprints and mounting procedures are identical.

Q: Are there any temperature or voltage derating considerations when substituting?

A: No. Both parts operate across the same temperature range (-55°C to 150°C) and are rated for identical voltage (400V) and current (6A) specifications.

Q: Which part should be selected for new applications?

A: The PB64-BP is classified as "Not For New Designs." For new product development, consult the manufacturer for current-generation bridge rectifier alternatives meeting the same electrical specifications.
