DF005M Bridge Rectifier Single Phase 50V 1.5A Equivalent & Substitute Parts

Part Overview

The DF005M is a single-phase bridge rectifier manufactured by onsemi, rated for 50 V peak reverse voltage and 1.5 A average rectified current in a through-hole 4-DIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The DF005M serves as a standard rectification solution for low-voltage AC-to-DC conversion circuits requiring moderate current capacity.

Substitute Part Grouping Explanation

Substitution of the DF005M is determined by the following critical parameters:

Voltage Rating Compatibility: The peak reverse voltage must equal or exceed 50 V. Parts with higher voltage ratings (600 V, 800 V, 1 kV) are electrically compatible but represent over-specification for 50 V applications.

Current Rating Compatibility: The average rectified current must equal or exceed 1.5 A. Parts rated at 1 A are under-specified and unsuitable. Parts rated at 1.5 A or higher are acceptable.

Mounting Type: Through-hole mounting is required for direct PCB compatibility with DF005M footprints. Surface-mount alternatives require circuit board redesign.

Package Dimensions: The 4-EDIP package with 0.300" (7.62mm) spacing is the primary form factor. Variants with 0.321" (8.15mm) spacing (DB-series) have different pin spacing and require footprint verification.

Diode Technology: Standard single-phase bridge rectifier technology is consistent across all candidates.

Compliance Requirements: RoHS3 compliance is maintained across all substitute options.

Engineering Selection Recommendations

Direct Equivalent (Recommended for Replacement):

DB151 from SMC Diode Solutions is the closest functional equivalent to DF005M. It maintains identical voltage (50 V) and current (1.5 A) ratings, matching operating temperature range, and RoHS3 compliance. The primary consideration is package spacing: DB151 uses 0.321" (8.15mm) pin spacing versus DF005M's 0.300" (7.62mm). PCB footprint verification is required before substitution.

Higher Voltage Alternatives (Over-Specification):

DF06M (onsemi) provides 600 V rating with 1.5 A current capacity in the original 0.300" (7.62mm) package. This part maintains onsemi manufacturing continuity and identical package dimensions, eliminating footprint concerns. Voltage over-specification does not degrade performance in 50 V applications.

DB105-BP, DB106-BP, and DB107-BP (Micro Commercial Co) offer 600 V, 800 V, and 1 kV ratings respectively, all at 1 A current capacity. These parts are electrically compatible but under-specified for current (1 A versus 1.5 A requirement). Product status is Active for DB105-BP, DB106-BP, and DB107-BP, supporting long-term availability.

Not Recommended:

BGX50AE6327HTSA1 (Infineon) is surface-mount only and rated at 140 mA, insufficient for 1.5 A applications. Circuit board redesign would be required.

DB101-BP, DB102-BP, DB103-BP, and DB104-BP carry "Not For New Designs" status, indicating obsolescence trajectory similar to DF005M.

Frequently Asked Questions (FAQ)

Q: Can DB151 replace DF005M directly on the PCB?

A: DB151 is electrically equivalent but has different pin spacing (0.321" versus 0.300"). Footprint compatibility must be verified. If the PCB footprint accommodates 0.321" spacing, direct substitution is possible. Otherwise, adapter solutions or PCB modification is required.

Q: Why are higher voltage parts like DB105-BP or DF06M acceptable substitutes?

A: Bridge rectifiers operate safely at voltages below their peak reverse rating. A 600 V rated part functions correctly in a 50 V circuit. The higher voltage rating provides design margin without performance degradation. Current rating remains the limiting factor.

Q: Is DB101-BP a suitable replacement despite 1 A rating?

A: No. DB101-BP is rated for 1 A average rectified current, while DF005M requires 1.5 A. Operating at 150% of rated current causes excessive heat generation and reduces component lifespan. Current rating must equal or exceed the application requirement.

Q: What is the difference between DF005M and DF06M?

A: Both are onsemi products in identical 4-EDIP (0.300", 7.62mm) packages. DF005M is rated 50 V / 1.5 A; DF06M is rated 600 V / 1.5 A. DF06M provides higher voltage specification with equivalent current capacity and maintains the same package footprint.

Q: Why is BGX50AE6327HTSA1 not recommended?

A: BGX50AE6327HTSA1 is a surface-mount component rated at 140 mA, insufficient for 1.5 A applications. Through-hole to surface-mount conversion requires complete circuit board redesign. Current rating is the primary disqualifying factor.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance, consistent with DF005M specifications.

Q: What is the impact of different forward voltage specifications?

A: Forward voltage differences (1.1 V @ 1 A for DF005M versus 1.1 V @ 1.5 A for DB151) are negligible in rectifier applications. Both values fall within standard rectifier performance parameters and do not affect circuit functionality.
