DF005MA-E3/45 Equivalent & Substitute Parts

Part Overview

The DF005MA-E3/45 is a single-phase bridge rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This component operates at 50 V peak reverse voltage with 1 A average rectified current and is housed in a 4-EDIP through-hole package. The part is currently active and ROHS3 compliant. Equivalent and substitute parts are necessary when the primary part is unavailable, when alternative manufacturers are preferred for supply chain optimization, or when higher voltage ratings are required for circuit redesign.

Substitute Part Grouping Explanation

Substitution for the DF005MA-E3/45 is determined by the following criteria:

Parametric Equivalents maintain identical electrical specifications: 50 V peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A, and through-hole mounting in a 4-EDIP package. These parts are direct replacements with no circuit modifications required.

Manufacturer Recommended Substitutes from Micro Commercial Co (DB101-BP through DB107-BP) share the same diode type, technology, current rating, forward voltage, and operating temperature range. However, these parts feature different voltage ratings (100 V to 1 kV) and package dimensions (0.321" vs 0.300"), requiring evaluation for specific circuit requirements.

Higher Voltage Alternatives (DB104-BP, DB105-BP, DB106-BP, DB107-BP) are suitable when circuit voltage requirements exceed 50 V, provided PCB layout accommodates the slightly larger package footprint.

Engineering Selection Recommendations

Direct Replacement (No Circuit Modification Required): DF005M-E3/45 is the primary parametric equivalent, sharing identical voltage, current, and package specifications with the DF005MA-E3/45. Both parts are active and ROHS3 compliant.

Alternative Manufacturer Selection: DB101-BP from Micro Commercial Co provides electrical equivalence at 50 V and 1 A but carries a "Not For New Designs" status. This part is suitable only for legacy system maintenance or repair applications where the original specification must be maintained. The package footprint is slightly larger (0.321" vs 0.300"), requiring PCB layout verification.

Higher Voltage Requirements: DB105-BP (600 V) and DB106-BP (800 V) are active products suitable for circuits requiring higher voltage ratings. DB107-BP (1 kV) is also available. These parts maintain 1 A current rating and identical forward voltage characteristics but require PCB layout accommodation for the larger package dimension.

Fairchild DF005M: This part offers an extended lower operating temperature limit (-65°C vs -55°C) and is active. The package footprint matches the original specification. Reverse leakage current is 10 µA at 50 V compared to 5 µA for the DF005MA-E3/45.

Frequently Asked Questions (FAQ)

Q: Can DB101-BP be used as a direct replacement for DF005MA-E3/45? A: DB101-BP is electrically equivalent at 50 V and 1 A but carries a "Not For New Designs" status. It is suitable for repair and maintenance only. The package footprint is 0.321" compared to 0.300", requiring PCB layout verification before substitution.

Q: What is the difference between DF005M-E3/45 and DF005MA-E3/45? A: Both parts share identical electrical specifications and package dimensions. DF005M-E3/45 is the direct parametric equivalent and is the recommended substitute.

Q: Can I use DB105-BP or DB106-BP if my circuit only requires 50 V? A: Yes. Higher voltage-rated bridge rectifiers operate safely at lower voltages. However, the larger package footprint (0.321" vs 0.300") must be accommodated on the PCB. Verify that the increased package size does not create layout conflicts.

Q: What is the significance of the "Not For New Designs" status on DB101-BP through DB104-BP? A: This status indicates that these parts are in mature or declining production phases. They are suitable for maintaining existing products but should not be selected for new circuit designs. DB105-BP, DB106-BP, and DB107-BP are active and appropriate for new designs.

Q: How does the reverse leakage current affect part selection? A: The DF005MA-E3/45 specifies 5 µA reverse leakage at 50 V. Substitute parts from Micro Commercial Co and Fairchild specify 10 µA. This difference is negligible for most applications but should be evaluated in high-impedance or precision analog circuits.

Q: Is the Fairchild DF005M suitable for applications requiring extended low-temperature operation? A: Yes. The Fairchild DF005M operates from -65°C compared to -55°C for the DF005MA-E3/45, providing an additional 10°C of low-temperature margin. This part is active and ROHS3 compliant.
