PB61 Bridge Rectifier Single Phase 100V 6A Equivalent & Substitute Parts

Part Overview

The PB61 is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 100V peak reverse voltage and 6A average rectified current. This component is classified as obsolete, making substitute parts necessary for ongoing production and maintenance applications. The PB61 operates across a wide temperature range of -55°C to 150°C and is housed in a 4-Square PB-6 through-hole package.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PB61 is determined by electrical and mechanical parameter equivalence. The substitute part PB61-BP maintains identical electrical specifications across all critical parameters: single-phase rectification, 100V peak reverse voltage rating, 6A average rectified current, forward voltage characteristics, reverse leakage current, and operating temperature range. Both parts use the same 4-Square PB-6 through-hole package, ensuring mechanical compatibility in existing PCB layouts and assembly processes.

The substitution is valid based on the following key parameters:

• Diode Type: Single Phase
• Voltage - Peak Reverse (Max): 100 V
• Current - Average Rectified (Io): 6 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 3 A
• Current - Reverse Leakage @ Vr: 10 µA @ 100 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Package / Case: 4-Square, PB-6

Parameter Comparison

Engineering Selection Recommendations

The PB61-BP serves as the direct substitute for the obsolete PB61. Both parts are manufactured by Micro Commercial Co and maintain identical electrical and mechanical specifications. The primary distinction is product status and compliance: the PB61 is obsolete, while the PB61-BP is designated as not for new designs but remains available for replacement and maintenance applications.

The PB61-BP offers improved compliance status, meeting ROHS3 requirements compared to the PB61's non-compliant status. For applications requiring RoHS compliance, the PB61-BP is the appropriate selection. Both parts maintain REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can PB61-BP directly replace PB61 in existing designs? A: Yes. The PB61-BP maintains identical electrical ratings (100V, 6A), forward voltage characteristics, reverse leakage specifications, and operating temperature range. The 4-Square PB-6 through-hole package is mechanically identical, allowing direct PCB substitution without layout modifications.

Q: What is the difference between PB61 and PB61-BP? A: The primary differences are packaging format (tape/reel versus bulk) and compliance status. The PB61-BP is ROHS3 compliant, whereas the PB61 is RoHS non-compliant. Electrical and thermal specifications are identical.

Q: Are there any temperature or voltage derating considerations when substituting? A: No. Both parts operate across the identical temperature range (-55°C to 150°C) and maintain the same voltage ratings and current specifications. No derating adjustments are required.

Q: Is the PB61-BP suitable for new product designs? A: The PB61-BP is designated as not for new designs. For new designs, alternative bridge rectifier solutions with active production status should be evaluated. The PB61-BP is appropriate for replacement and maintenance of existing equipment using the original PB61.

Q: What packaging options are available? A: The PB61 is supplied in standard packaging, while the PB61-BP is available in bulk packaging. Both use the 4-Square PB-6 through-hole package format.
