PB66 Bridge Rectifier - Equivalent & Substitute Parts

Part Overview

The PB66 is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 600 V peak reverse voltage and 6 A average rectified current. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement. The PB66-BP serves as the direct functional equivalent, offering identical electrical and mechanical specifications while maintaining active product status.

Key Parameters

Substitute Part Grouping Explanation

The PB66-BP qualifies as a direct substitute based on the following criteria:

• Identical diode type (single phase) and technology (standard)
• Matching voltage rating: 600 V peak reverse voltage
• Matching current rating: 6 A average rectified current
• Identical forward voltage characteristic: 1.1 V @ 3 A
• Identical reverse leakage current: 10 µA @ 600 V
• Identical operating temperature range: -55°C to 150°C
• Identical mounting type and package: Through Hole, 4-Square PB-6
• Supplier device package designation: PB-6

The substitution is based strictly on electrical parameter equivalence and mechanical compatibility. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The PB66-BP is the appropriate selection for new designs and procurement activities. While the PB66 remains electrically and mechanically equivalent, its obsolete status creates supply chain risk. The PB66-BP maintains identical performance characteristics across all specified electrical parameters and physical form factor, ensuring direct functional compatibility in existing circuit designs.

The PB66-BP additionally provides ROHS3 compliance, addressing regulatory requirements for new product development and manufacturing in restricted substance environments. Both parts maintain REACH unaffected status and identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can PB66-BP replace PB66 in existing designs? A: Yes. The PB66-BP is electrically and mechanically identical to the PB66 across all specified parameters, including voltage rating, current rating, forward voltage, reverse leakage, operating temperature range, and package configuration. Direct substitution is supported without circuit modification.

Q: What is the primary difference between PB66 and PB66-BP? A: The PB66 is classified as obsolete with RoHS non-compliant status, while the PB66-BP is active and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts? A: No. Both parts use identical Through Hole mounting with 4-Square PB-6 package configuration and supplier device package designation.

Q: Does the PB66-BP meet current regulatory requirements? A: Yes. The PB66-BP is ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and distribution.

Q: What are the critical electrical parameters for substitution? A: Substitution is valid when the following parameters match: peak reverse voltage (600 V), average rectified current (6 A), forward voltage (1.1 V @ 3 A), reverse leakage current (10 µA @ 600 V), and operating temperature range (-55°C to 150°C).
