DB155-BP Bridge Rectifier Single Phase 600V 1.5A Equivalent & Substitute Parts

Part Overview

The DB155-BP is a single-phase bridge rectifier diode manufactured by Micro Commercial Co, rated for 600V peak reverse voltage and 1.5A average rectified current. This component is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. Finding equivalent or substitute parts is necessary for maintenance, repair, and legacy system support where the original part is unavailable or inventory is depleted.

Substitute Part Grouping Explanation

Substitution eligibility for the DB155-BP is determined by strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Diode Type: Single Phase (required match)
• Technology: Standard (required match)
• Voltage - Peak Reverse (Max): 600 V (required match)
• Current - Average Rectified (Io): 1.5 A (required match)
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1.5 A (required match)
• Operating Temperature Range: -55°C to 150°C (TJ) (required match)
• Mounting Type: Through Hole (required match)
• Package / Case: 4-EDIP (0.321", 8.15mm) (required match)

Secondary Consideration:

• Current - Reverse Leakage @ Vr: Equivalent or lower values are acceptable (10 µA @ 600 V baseline)

All identified substitute parts meet these criteria and are therefore electrically and mechanically compatible with the DB155-BP in applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

DB155L-BP (Micro Commercial Co): This part is the direct equivalent from the same manufacturer. It maintains identical electrical specifications and package configuration while offering Active product status. Selection of DB155L-BP is appropriate for direct replacement in existing designs and for new applications requiring this specification class.

DB155G (GeneSiC Semiconductor): This part meets all electrical and mechanical substitution criteria. It offers Active product status and demonstrates improved reverse leakage performance (5 µA @ 600 V versus 10 µA @ 600 V). RoHS Compliance and MSL Level 1 certification are provided. Selection of DB155G is appropriate where improved leakage characteristics are beneficial or where GeneSiC Semiconductor supply chain availability is preferred.

Both substitute parts are suitable for direct replacement of DB155-BP in applications where the specified electrical and thermal parameters are required.

Frequently Asked Questions (FAQ)

Q: Can DB155L-BP be used as a direct replacement for DB155-BP?

A: Yes. DB155L-BP is electrically and mechanically equivalent to DB155-BP. Both parts share identical ratings for peak reverse voltage (600V), average rectified current (1.5A), forward voltage (1.1V @ 1.5A), reverse leakage (10 µA @ 600V), operating temperature range (-55°C to 150°C), and package configuration (4-EDIP). The primary difference is product status: DB155L-BP is Active while DB155-BP is Not For New Designs.

Q: What is the difference between DB155G and DB155-BP?

A: DB155G and DB155-BP are electrically equivalent with one exception: DB155G exhibits lower reverse leakage current (5 µA @ 600V) compared to DB155-BP (10 µA @ 600V). All other electrical parameters and the package configuration are identical. DB155G is manufactured by GeneSiC Semiconductor and carries Active product status with RoHS Compliance certification.

Q: Are all three parts (DB155-BP, DB155L-BP, DB155G) pin-compatible?

A: Yes. All three parts use the 4-EDIP (0.321", 8.15mm) package configuration and are pin-compatible for through-hole mounting applications.

Q: Which substitute should be selected for new designs?

A: For new designs, either DB155L-BP or DB155G should be selected, as both carry Active product status. DB155-BP is designated "Not For New Designs" and should be reserved for legacy system support and repair applications only.

Q: Does reverse leakage current difference affect substitution suitability?

A: The lower reverse leakage of DB155G (5 µA @ 600V) is within acceptable substitution parameters. Applications sensitive to leakage current may benefit from DB155G selection, while applications with standard leakage tolerance requirements can use either DB155L-BP or DB155G.

Q: What compliance certifications are provided?

A: DB155-BP and DB155L-BP carry REACH Unaffected status. DB155G carries REACH Unaffected status, RoHS Compliance, and MSL Level 1 (Unlimited) certification. All three parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.
