DF10M Bridge Rectifier Single Phase 1 kV 1.5 A Equivalent & Substitute Parts

Part Overview

The DF10M is a single-phase bridge rectifier diode manufactured by onsemi, rated for 1 kV peak reverse voltage and 1.5 A average rectified current in a 4-DIP through-hole package. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design alternatives. Substitute parts are selected based on matching or exceeding electrical performance within the single-phase bridge rectifier category while maintaining compatible through-hole mounting.

Substitute Part Grouping Explanation

Substitution logic for the DF10M is based on the following criteria:

Primary Substitution Criteria:

Diode Type: Single Phase (required match)
Technology: Standard (required match)
Mounting Type: Through Hole (required match)
Voltage - Peak Reverse (Max): Equal to or greater than 1 kV
Current - Average Rectified (Io): Equal to or greater than 1.5 A
Operating Temperature Range: Must encompass or match -55°C ~ 150°C

Secondary Compatibility Factors:

Package mechanical compatibility (4-EDIP form factor preferred)
Forward voltage characteristics (1.1 V @ rated current or lower)
Reverse leakage specifications (5 µA @ rated voltage or lower)

Parts are grouped into two categories: direct equivalents (matching all primary criteria) and functional substitutes (meeting electrical requirements with potential package variations).

Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Substitute):

DB157 from SMC Diode Solutions is the primary recommended substitute for DF10M. It matches all critical electrical parameters: 1 kV peak reverse voltage, 1.5 A average rectified current, 1.1 V forward voltage, and 5 µA reverse leakage. Operating temperature range is identical (-55°C ~ 150°C). The part is currently in active production status with ROHS3 compliance. Package dimensions differ slightly (0.321" vs 0.300" body width), but both are 4-EDIP through-hole configurations with compatible pin spacing for standard PCB layouts.

Secondary Substitutes (Voltage-Rated Alternatives):

DB107-BP (Micro Commercial Co) provides 1 kV voltage rating with 1 A current capacity. This part is suitable for applications where the 1.5 A current requirement can be reduced to 1 A. Active production status and ROHS3 compliance are confirmed. Package is 4-EDIP (0.321", 8.15mm).

DB106-BP (Micro Commercial Co) provides 800 V voltage rating with 1 A current capacity. This part is applicable only to systems where peak reverse voltage does not exceed 800 V. Active production status and ROHS3 compliance are confirmed.

Lower Voltage Alternatives (Application-Dependent):

DB105-BP, DB104-BP, DB103-BP, and DB102-BP are available in descending voltage ratings (600 V, 400 V, 200 V, 100 V respectively), all with 1 A current capacity. These parts are suitable only for applications with correspondingly lower voltage requirements. DB105-BP and DB106-BP maintain active status; DB104-BP and lower are marked "Not For New Designs."

Compliance Status:

All recommended substitutes maintain ROHS3 compliance and REACH compliance status consistent with the original DF10M specification. All parts are classified under HTSUS 8541.10.0080 and ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can DB157 be used as a direct replacement for DF10M in existing designs?

A: DB157 is electrically equivalent to DF10M with matching voltage and current ratings. Package dimensions differ slightly (0.321" vs 0.300" body width), but both use standard 4-EDIP through-hole pin spacing. PCB layout compatibility should be verified for tight spacing applications, though standard through-hole designs typically accommodate this variation.

Q: What is the difference between DB157 and DB107-BP?

A: DB157 is rated for 1.5 A average rectified current, while DB107-BP is rated for 1 A. Both operate at 1 kV peak reverse voltage. DB157 should be selected for applications requiring the full 1.5 A current capacity. DB107-BP is suitable only where current demand does not exceed 1 A.

Q: Can lower voltage-rated parts (DB105-BP, DB104-BP) substitute for DF10M?

A: Lower voltage-rated parts are not suitable substitutes for DF10M. The DF10M is rated for 1 kV peak reverse voltage. Using parts rated for 600 V, 400 V, or lower creates risk of diode failure if reverse voltage exceeds the part rating. Substitution is only valid when the substitute part voltage rating equals or exceeds the original specification.

Q: Why is DF005M listed as a substitute if it has only 50 V rating?

A: DF005M is listed in the provided substitute data but is not recommended for direct replacement of DF10M due to its 50 V voltage rating, which is significantly below the 1 kV requirement. DF005M is applicable only to applications with 50 V or lower voltage requirements.

Q: Are all recommended substitutes ROHS3 compliant?

A: Yes. DB157, DB107-BP, DB106-BP, DB105-BP, and DF005M all carry ROHS3 compliance certification. Compliance status is consistent across all active production alternatives.

Q: What is the operating temperature range for substitute parts?

A: DB157, DB107-BP, DB106-BP, DB105-BP, DB104-BP, DB103-BP, and DB102-BP all operate across -55°C ~ 150°C (TJ), matching the DF10M specification. DF005M extends the lower temperature limit to -65°C, providing wider temperature coverage if required by application.

Q: Can package dimension differences affect PCB compatibility?

A: Both DF10M (0.300" body width) and substitute parts like DB157 (0.321" body width) use standard 4-EDIP through-hole pin spacing. Standard PCB designs accommodate this variation. However, designs with tight component spacing or custom footprints should verify mechanical clearance before substitution.
