PB605 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The PB605 is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 50 V peak reverse voltage and 6 A average rectified current. This component is classified as obsolete, which necessitates identification of suitable substitute parts for ongoing production and maintenance applications. The through-hole PB-6 package configuration and standard rectification technology establish the baseline for equivalent part selection.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PB605 are identified based on electrical and mechanical parameter equivalence. The critical parameters determining substitutability are:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 50 V
• Current - Average Rectified (Io): 6 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 3 A
• Current - Reverse Leakage @ Vr: 10 µA @ 50 V
• Operating Temperature Range: -55°C to 150°C (TJ)
• Mounting Type: Through Hole
• Package / Case: 4-Square, PB-6

The PB605-BP variant meets all electrical specifications and mechanical requirements, differing only in packaging format (bulk versus standard) and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The PB605-BP is electrically and mechanically equivalent to the PB605 across all specified parameters. The primary distinction is regulatory compliance: PB605-BP achieves ROHS3 compliance, whereas the original PB605 is non-compliant. For applications subject to RoHS requirements, PB605-BP is the appropriate selection. Both parts maintain identical electrical performance characteristics and thermal operating ranges. The PB605-BP product status designation as "Not For New Designs" reflects its classification within the manufacturer's portfolio; however, electrical equivalence remains complete.

Frequently Asked Questions (FAQ)

Q: Can PB605-BP be used as a direct replacement for PB605?

A: Yes. PB605-BP is electrically and mechanically equivalent to PB605. All electrical parameters, including voltage ratings, current ratings, forward voltage, reverse leakage, and operating temperature range are identical. The through-hole PB-6 package configuration is unchanged.

Q: What is the difference between PB605 and PB605-BP?

A: The primary differences are packaging format (standard versus bulk) and regulatory compliance. PB605-BP is ROHS3 compliant, while PB605 is not. Both parts are manufactured by Micro Commercial Co and share identical electrical specifications.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts operate across the same temperature range (-55°C to 150°C TJ) and deliver identical electrical performance at rated conditions.

Q: Does the bulk packaging of PB605-BP affect component functionality?

A: No. Packaging format does not affect electrical or mechanical performance. Bulk packaging refers to distribution method only.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, PB605-BP is appropriate. Both parts are classified outside active new design portfolios; however, PB605-BP offers superior regulatory alignment.
