DF005M/45 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF005M/45 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division, rated for 50 V peak reverse voltage and 1 A average rectified current. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The part is housed in a 4-EDIP (0.300", 7.62mm) through-hole package and complies with ROHS3 and REACH standards.

Substitute Part Grouping Explanation

Substitution for the DF005M/45 is determined by the following critical parameters:

Voltage - Peak Reverse (Max): Must equal or exceed 50 V
Current - Average Rectified (Io): Must equal or exceed 1 A
Diode Type: Single Phase
Technology: Standard
Mounting Type: Through Hole
Package Compatibility: Physical dimensions must accommodate 4-EDIP form factor

Direct substitutes maintain identical electrical ratings (50 V, 1 A) with compatible packaging. Higher voltage-rated parts (100 V, 200 V, 400 V, 600 V, 800 V, 1 kV) are functionally compatible in 50 V applications but represent over-specification. The DF005M-E3/45 from Vishay is the direct equivalent with active product status. The DB101-BP from Micro Commercial Co provides functional equivalence with minor package dimension variation (0.321" vs 0.300").

Engineering Selection Recommendations

Primary Recommendation: DF005M-E3/45

The DF005M-E3/45 is the optimal substitute for the obsolete DF005M/45. Both parts are manufactured by Vishay General Semiconductor with identical electrical specifications (50 V, 1 A, 1.1 V forward voltage, 5 µA reverse leakage). The DF005M-E3/45 maintains active product status and ROHS3 compliance. Packaging dimensions are identical (4-EDIP 0.300", 7.62mm), ensuring direct board-level compatibility without layout modifications.

Secondary Recommendation: DB101-BP

The DB101-BP from Micro Commercial Co provides functional equivalence with 50 V peak reverse voltage and 1 A current rating. This part is rated "Not For New Designs" but remains available with 1542 units in stock. Package dimensions differ slightly (0.321" vs 0.300"), requiring verification of PCB footprint clearance. Reverse leakage current is specified at 10 µA versus 5 µA for the original part.

Higher Voltage Alternatives: DB102-BP through DB107-BP

Parts rated for 100 V, 200 V, 400 V, 600 V, 800 V, and 1 kV are functionally compatible in 50 V applications. These represent over-specification and are suitable only when higher voltage margin is required by circuit design. DB105-BP (600 V) and DB106-BP (800 V) maintain active product status with substantial inventory availability (25,756 and 5,744 units respectively).

Alternative: DF005M (Fairchild Semiconductor)

The DF005M from Fairchild Semiconductor provides identical 50 V, 1 A ratings with extended operating temperature range (-65°C to 150°C versus -55°C to 150°C). Package dimensions match the original (4-EDIP 0.300", 7.62mm). This part is active with 2,660 units in stock. RoHS compliance status is not specified in available data.

Frequently Asked Questions (FAQ)

Q: Can I use DB101-BP as a direct replacement for DF005M/45?

A: DB101-BP is electrically compatible with identical 50 V and 1 A ratings. However, package dimensions differ (0.321" versus 0.300" width). Verify that your PCB footprint accommodates the slightly larger package before substitution. Reverse leakage current is higher (10 µA vs 5 µA), which is acceptable in most applications but should be evaluated for precision circuits.

Q: Why would I select a higher voltage-rated part like DB105-BP (600 V) instead of DB101-BP (50 V)?

A: Higher voltage-rated parts are functionally compatible in lower voltage applications and provide additional safety margin. Selection depends on circuit requirements and cost considerations. DB105-BP and DB106-BP offer active product status and superior inventory availability compared to 50 V alternatives.

Q: Is DF005M-E3/45 a true equivalent to DF005M/45?

A: Yes. Both parts are manufactured by Vishay with identical electrical specifications, operating temperature range, and package dimensions. The primary difference is product status: DF005M-E3/45 is active while DF005M/45 is obsolete. The DF005M-E3/45 is the recommended direct replacement.

Q: What is the significance of the package dimension difference between 0.300" and 0.321"?

A: The 0.300" dimension (DF005M/45, DF005M-E3/45, DF005M) represents the standard DFM package width. The 0.321" dimension (DB series parts) represents the DB-1 package width. This 0.021" difference requires PCB footprint verification. Consult your board layout design rules before substituting between these package families.

Q: Are all listed parts ROHS3 compliant?

A: All parts except DF005M (Fairchild) explicitly state ROHS3 compliance. The Fairchild DF005M does not specify RoHS status in available documentation. Confirm compliance requirements with your procurement or quality department before selection.

Q: What is the difference between DF005M and DF005M/45?

A: Both parts share identical electrical specifications (50 V, 1 A). The "/45" designation in DF005M/45 indicates a specific packaging or distribution variant. The DF005M from Fairchild provides equivalent functionality with extended temperature range (-65°C to 150°C).
