DF01M Bridge Rectifier Single Phase 100V 1.5A Equivalent & Substitute Parts

Part Overview

The DF01M is a single-phase bridge rectifier diode manufactured by onsemi, rated for 100 V peak reverse voltage and 1.5 A average rectified current in a 4-DIP through-hole package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating mechanical package variations.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Electrical Compatibility Requirements:

Voltage - Peak Reverse (Max) must equal or exceed 100 V
Current - Average Rectified (Io) must equal or exceed 1.5 A
Voltage - Forward (Vf) must not exceed 1.1 V at rated current
Current - Reverse Leakage must not exceed 10 µA at rated voltage
Operating Temperature Range must encompass -55°C to 150°C

Mechanical Compatibility Requirements:

Diode Type: Single Phase (mandatory)
Technology: Standard (mandatory)
Mounting Type: Through Hole (mandatory)
Package / Case: 4-EDIP form factor (allows minor dimensional variations within 0.300" to 0.321" pitch range)

Compliance Requirements:

RoHS3 Compliant status preferred for new designs
REACH compliance status noted where applicable

Substitute parts are grouped by voltage rating. Parts rated below 100 V are not direct substitutes but may serve in lower-voltage applications. Parts rated at 100 V or higher with 1.5 A or greater current capacity are considered equivalent or upgradeable substitutes.

Engineering Selection Recommendations

Direct Equivalent (100 V, 1.5 A Rating):

DB152 is the primary active substitute for DF01M. It matches the 100 V voltage rating and 1.5 A current capacity with identical forward voltage characteristics. The reverse leakage is lower (5 µA vs. 10 µA), representing improved performance. Package pitch differs slightly (0.321" vs. 0.300"), but both are 4-EDIP form factors compatible with standard through-hole PCB layouts. DB152 is Active status and RoHS3 Compliant, suitable for new designs.

Voltage-Rated Upgrades (1.5 A Current Capacity):

DF06M provides the same 1.5 A current rating at elevated voltage (600 V). This part is suitable for applications requiring higher voltage margin. DF06M is manufactured by onsemi with identical thermal range and package form factor to DF01M. However, DF06M is classified as Obsolete.

Current-Limited Alternatives (100 V Rating):

DB102-BP matches the 100 V voltage rating but is limited to 1 A average rectified current. This part is suitable only for applications where 1 A current capacity is sufficient. DB102-BP is classified as Not For New Designs.

Voltage-Elevated Alternatives (1 A Current Capacity):

DB103-BP, DB104-BP, DB105-BP, DB106-BP, and DB107-BP provide progressively higher voltage ratings (200 V, 400 V, 600 V, 800 V, 1000 V respectively) at 1 A current capacity. These parts are suitable for applications requiring higher voltage withstand capability but lower current. DB105-BP, DB106-BP, and DB107-BP are Active status. DB103-BP and DB104-BP are Not For New Designs.

Lower Voltage Alternative:

DF005M is rated for 50 V at 1 A, making it unsuitable as a direct substitute for 100 V applications. This part is included for reference only in lower-voltage system contexts.

Frequently Asked Questions (FAQ)

Q: Can DB152 directly replace DF01M in existing designs?

A: DB152 is electrically equivalent to DF01M at the 100 V, 1.5 A rating. Both are single-phase standard bridge rectifiers with identical forward voltage and thermal range. The package pitch difference (0.321" vs. 0.300") is within standard 4-EDIP tolerance and compatible with through-hole PCB layouts. DB152 is Active status, making it the recommended substitute.

Q: Why are DB101-BP through DB107-BP listed if they have only 1 A current capacity?

A: These parts are listed because they share the single-phase bridge rectifier topology and through-hole 4-EDIP package form factor. However, their 1 A current rating is below the DF01M specification of 1.5 A. They are suitable only for applications where current demand does not exceed 1 A. Selection depends on actual circuit requirements.

Q: What is the significance of the package pitch difference between DF01M (0.300") and DB152 (0.321")?

A: Both parts use the 4-EDIP (Dual In-line Package) form factor with through-hole leads. The pitch difference of 0.021" is within standard manufacturing tolerance for this package family. PCB layouts designed for standard 4-EDIP spacing accommodate both variants without modification.

Q: Is DF06M a suitable upgrade for DF01M?

A: DF06M provides the same 1.5 A current capacity and identical thermal range as DF01M but at 600 V peak reverse voltage versus 100 V. This represents a voltage upgrade suitable for applications requiring higher voltage margin. However, DF06M is classified as Obsolete, limiting its availability for new procurement.

Q: What compliance certifications apply to substitute parts?

A: DB152 is RoHS3 Compliant and REACH Affected. DF06M is RoHS3 Compliant and REACH Unaffected. DB102-BP, DB103-BP, DB104-BP, DB105-BP, DB106-BP, and DB107-BP are all RoHS3 Compliant and REACH Unaffected. Compliance requirements depend on end-application regulatory jurisdiction.

Q: Can lower-voltage parts like DF005M be used in place of DF01M?

A: No. DF005M is rated for 50 V peak reverse voltage, which is insufficient for applications designed for 100 V operation. Using an undersized voltage-rated component creates risk of diode failure and circuit malfunction. Substitute parts must meet or exceed the original voltage specification.
