DF15005S-G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF15005S-G is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 50 V peak reverse voltage and 1.5 A average rectified current. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). Bridge rectifiers in this specification range are essential for AC-to-DC conversion applications requiring reliable full-wave rectification in compact surface-mount form factors. Substitute parts become necessary when addressing supply chain constraints, design revisions, or specific packaging requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the DF15005S-G is determined by strict alignment of the following electrical and mechanical parameters:

Voltage - Peak Reverse (Max): 50 V (exact match required)
Current - Average Rectified (Io): 1.5 A minimum (equal or higher acceptable)
Diode Type: Single Phase (exact match required)
Technology: Standard (exact match required)
Mounting Type: Surface Mount (exact match required)
Package / Case: 4-SMD, Gull Wing (exact match required)
Operating Temperature Range: Must encompass or equal the specified range
RoHS Status: ROHS3 Compliant (compliance required)

The substitute parts identified meet these criteria with variations in current rating, forward voltage characteristics, and reverse leakage specifications within acceptable tolerances for this product category.

Engineering Selection Recommendations

DF005S (onsemi): This part maintains electrical parity with the DF15005S-G across voltage and current ratings. However, onsemi has designated this part as "Not For New Designs," indicating end-of-life trajectory. Selection of this substitute should be limited to legacy system support or existing inventory utilization where supply continuity is the primary driver.

DF005S-T (Diodes Incorporated): This part is designated Active product status and represents the preferred substitute option. It maintains the 50 V peak reverse voltage specification and 4-SMD Gull Wing package compatibility. The current rating is specified at 1 A, which is lower than the DF15005S-G 1.5 A rating. This part is suitable for applications where the load current does not exceed 1 A. The extended operating temperature range (-65°C to 150°C) provides additional thermal margin compared to the main part. RoHS3 compliance and unlimited MSL rating ensure regulatory and manufacturing process compatibility.

Frequently Asked Questions (FAQ)

Q: Can DF005S (onsemi) be used as a direct replacement for DF15005S-G?

A: Electrical parameters are compatible (50 V, 1.5 A rating, 1.1 V forward voltage, 5 µA reverse leakage). However, onsemi has classified this part as "Not For New Designs," indicating reduced long-term availability. Use only for legacy applications or existing inventory management.

Q: What is the key limitation of DF005S-T (Diodes Incorporated) as a substitute?

A: The average rectified current rating is specified at 1 A, compared to 1.5 A for the DF15005S-G. This part is suitable only for applications where the maximum load current does not exceed 1 A. Verify circuit current requirements before selection.

Q: Are all substitute parts in the same package?

A: Yes. All parts listed—DF15005S-G, DF005S, and DF005S-T—use 4-SMD Gull Wing surface-mount packaging, ensuring PCB layout and reflow process compatibility without design modification.

Q: Do substitute parts meet the same compliance standards?

A: Yes. All parts are RoHS3 compliant with MSL 1 (unlimited moisture sensitivity level), REACH unaffected status, and ECCN EAR99 classification, matching the regulatory profile of the DF15005S-G.

Q: What is the temperature operating range difference?

A: DF15005S-G and DF005S (onsemi) both specify -55°C to 150°C. DF005S-T (Diodes Incorporated) extends the lower limit to -65°C, providing 10°C additional cold-temperature margin. This may be advantageous for applications in extreme environmental conditions.

Q: Can I use DF005S-T in a design originally specified for DF15005S-G?

A: Substitution is valid only if the circuit load current does not exceed 1 A. If the application requires the full 1.5 A rating, DF005S-T is not suitable. Verify actual circuit current draw before implementation.
