PB68 Bridge Rectifier Single Phase 800V 6A Equivalent & Substitute Parts

Part Overview

The PB68 is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 800V peak reverse voltage and 6A average rectified current. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The PB68 operates across a temperature range of -55°C to 150°C and is packaged in a 4-Square PB-6 through-hole configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PB68 is determined by strict equivalence across the following electrical and mechanical parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 800 V
• Current - Average Rectified (Io): 6 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 3 A
• Current - Reverse Leakage @ Vr: 10 µA @ 800 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Mounting Type: Through Hole
• Package / Case: 4-Square, PB-6

The PB68-BP meets all these criteria and is therefore a direct functional equivalent. The primary distinction between the main part and its substitute is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The PB68-BP is the direct substitute for the obsolete PB68. Both components share identical electrical specifications and mechanical form factors. The PB68-BP is currently in active production status with ROHS3 compliance certification, whereas the PB68 is obsolete and RoHS non-compliant. For new designs and ongoing procurement, the PB68-BP is the appropriate selection. The PB68-BP is available in bulk packaging format, which may require adjustment to procurement and inventory management procedures compared to standard packaging of the original part.

Frequently Asked Questions (FAQ)

Q: Can the PB68-BP be used as a direct replacement for the PB68 in existing designs?

A: Yes. The PB68-BP is electrically and mechanically identical to the PB68. All electrical parameters, including voltage rating, current rating, forward voltage, reverse leakage, and operating temperature range are equivalent. The through-hole PB-6 package is identical, allowing direct PCB mounting without design modification.

Q: What is the difference between the PB68 and PB68-BP?

A: The primary differences are product status and packaging format. The PB68 is obsolete and RoHS non-compliant, while the PB68-BP is active production and ROHS3 compliant. The PB68-BP is supplied in bulk packaging rather than standard packaging. Electrical and mechanical specifications are identical.

Q: Does the bulk packaging of the PB68-BP affect component performance?

A: No. Bulk packaging is a supply and handling format only and does not affect electrical performance, reliability, or mechanical compatibility. The component itself is identical to standard packaging variants.

Q: Are there alternative manufacturers for this bridge rectifier specification?

A: This document addresses substitutes within the Micro Commercial Co product line. The PB68-BP is the specified equivalent for the PB68.

Q: What compliance certifications apply to the PB68-BP?

A: The PB68-BP is ROHS3 compliant and REACH unaffected. It carries ECCN classification EAR99 and HTSUS code 8541.10.0080.
