DF1501M Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF1501M is a single-phase bridge rectifier manufactured by Diodes Incorporated, rated for 100 V peak reverse voltage and 1.5 A average rectified current. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The DF1501M features a 4-EDIP (0.300", 7.62mm) through-hole package with DFM supplier designation and operates across -65°C to 150°C junction temperature range.

Substitute Part Grouping Explanation

Substitution of the DF1501M is determined by the following electrical and mechanical parameters:

Critical Substitution Parameters:

Diode Type: Single Phase (all substitutes must match)
Technology: Standard (all substitutes must match)
Mounting Type: Through Hole (all substitutes must match)
Voltage - Peak Reverse (Max): 100 V or higher (substitutes must meet or exceed)
Current - Average Rectified (Io): 1.5 A or higher (substitutes must meet or exceed)
Voltage - Forward (Vf) (Max): 1.1 V or lower (substitutes must not exceed)
Operating Temperature Range: Must support -65°C minimum or equivalent thermal performance
Package / Case: 4-EDIP form factor with compatible pin spacing

Substitute parts are grouped by voltage rating and current capacity. Parts meeting 100 V / 1.5 A or higher ratings with compatible through-hole packaging are direct substitutes. Parts with lower voltage or current ratings are not suitable for this application.

Engineering Selection Recommendations

Direct Substitutes (100 V Rating, 1.5 A or Higher):

DF201-G is the primary active substitute for DF1501M. It maintains 100 V peak reverse voltage rating, exceeds the 1.5 A current requirement at 2 A, and carries Active product status with ROHS3 compliance. Package spacing differs slightly (0.321" vs 0.300"), but both are 4-EDIP through-hole configurations suitable for standard PCB layouts.

Voltage-Rated Alternatives (100 V or Higher, Lower Current):

DB102-BP provides 100 V rating with 1 A current capacity. This part is rated below the DF1501M current specification and carries Not For New Designs status. Use only when current requirements can be reduced or when higher voltage margin is not required.

Higher Voltage Alternatives (Overvoltage Rated):

DB104-BP (400 V), DB105-BP (600 V), and DB106-BP (800 V) provide increased voltage margins for applications requiring higher transient protection. All three carry Active product status and ROHS3 compliance. Current ratings are 1 A, below the DF1501M specification. These parts are suitable only when application voltage requirements exceed 100 V and current can be managed at 1 A or lower.

Temperature-Matched Alternative:

DF005M matches the DF1501M operating temperature range (-65°C to 150°C) and maintains the 0.300" package spacing. However, it is rated for only 50 V and 1 A, making it unsuitable for 100 V applications.

Obsolete Equivalent:

DF06M provides 600 V / 1.5 A rating with matching 0.300" package spacing and -55°C to 150°C operating range. Product status is Obsolete, limiting its use to legacy system maintenance only.

Frequently Asked Questions (FAQ)

Q: Can DB102-BP replace DF1501M directly?

A: DB102-BP matches the 100 V voltage rating but is limited to 1 A average rectified current versus DF1501M's 1.5 A specification. Substitution is valid only if circuit design permits operation at reduced current capacity. Package spacing differs (0.321" vs 0.300"), requiring PCB layout verification.

Q: Why is DF201-G recommended as the primary substitute?

A: DF201-G maintains the 100 V peak reverse voltage rating and exceeds the 1.5 A current requirement at 2 A capacity. It carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory compliance. Minor package spacing difference (0.321" vs 0.300") is accommodated in standard through-hole PCB designs.

Q: Can higher voltage-rated parts like DB105-BP or DB106-BP be used?

A: Yes, higher voltage-rated parts are electrically compatible for 100 V applications. DB105-BP (600 V) and DB106-BP (800 V) provide additional voltage margin for transient protection. However, both are limited to 1 A current capacity, below the DF1501M specification. Use only when application current requirements do not exceed 1 A.

Q: What is the impact of package spacing differences?

A: DF1501M uses 0.300" (7.62mm) spacing; most substitutes use 0.321" (8.15mm) spacing. Both are standard 4-EDIP through-hole configurations. PCB footprint adjustment may be required. Verify pad spacing and hole diameter compatibility before assembly.

Q: Are there substitutes with matching -65°C minimum operating temperature?

A: DF005M and DF1501M both specify -65°C minimum operating temperature. DF005M is Active status but limited to 50 V / 1 A ratings. All other substitutes specify -55°C minimum, a 10°C reduction in low-temperature performance. Verify application requirements before selecting lower temperature-rated alternatives.

Q: Why are some substitutes marked "Not For New Designs"?

A: DB102-BP and DB104-BP carry "Not For New Designs" status, indicating manufacturer discontinuation plans. These parts remain available but are not recommended for new circuit development. Use Active-status parts (DF201-G, DB105-BP, DB106-BP) for new designs to ensure long-term supply continuity.
