SF24G-TP Equivalent & Substitute Parts

Part Overview

The SF24G-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 200 V DC reverse voltage and 2 A average rectified current in a DO-15 through-hole package. This diode is classified as Active product status and is RoHS3 compliant. Equivalent and substitute parts are identified based on matching electrical specifications, package compatibility, and thermal operating ranges. Alternative components may be required due to inventory availability, manufacturing discontinuation of related product lines, or specific application requirements for package form factors.

Substitute Part Grouping Explanation

Substitute parts for the SF24G-TP are grouped into two categories based on electrical parameter equivalence and package compatibility:

Parametric Equivalents (DO-15 Package): Parts that match all critical electrical specifications and use the same DO-15 package form factor. These include EGP20D, EGP20D-E3/54, and EGP20D-E3/73. These parts maintain identical voltage and current ratings, forward voltage characteristics, and fast recovery speed classification. Reverse recovery time values range from 35 ns to 50 ns, which falls within acceptable tolerance for general-purpose rectification applications.

Package Variant Equivalent (Axial Package): The MUR220RLG is a functionally equivalent part with identical electrical ratings but uses an axial (DO-41) package instead of the DO-15 package. This part is suitable for applications where axial lead configuration is acceptable or preferred.

Key Parameters Determining Substitution:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 950 mV @ 2 A
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Mounting Type: Through Hole
RoHS3 Compliance

Engineering Selection Recommendations

For Direct DO-15 Package Replacement:

EGP20D-E3/73 and EGP20D-E3/54 are the primary equivalents for the SF24G-TP. Both parts are manufactured by Vishay General Semiconductor - Diodes Division under the SUPERECTIFIER® series and maintain Active product status. These parts are suitable for new designs and carry identical electrical specifications with the exception of reverse recovery time (50 ns versus 35 ns for the SF24G-TP). Both parts are RoHS3 compliant and carry MSL rating of 1 (Unlimited).

EGP20D is a parametric equivalent with identical electrical characteristics but carries a product status of "Not For New Designs." This part is suitable for legacy system maintenance and repair applications only.

For Axial Package Configuration:

MUR220RLG, manufactured by onsemi under the SWITCHMODE™ series, provides electrical equivalence with an axial (DO-41) package configuration. This part is Active status and RoHS3 compliant. The operating temperature range extends to 175°C, providing enhanced thermal margin compared to the SF24G-TP. Reverse leakage current is lower at 2 µA @ 200 V. This part is suitable for applications where axial lead geometry is required or preferred for PCB layout.

Compliance Considerations:

All substitute parts listed are RoHS3 compliant and carry EAR99 ECCN classification, matching the regulatory status of the SF24G-TP. REACH status is "REACH Unaffected" for all parts.

Frequently Asked Questions (FAQ)

Q: Can EGP20D-E3/73 be used as a direct replacement for SF24G-TP in existing designs?

A: Yes. EGP20D-E3/73 is a direct DO-15 package equivalent with matching voltage (200 V), current (2 A), and forward voltage (950 mV @ 2 A) specifications. The reverse recovery time of 50 ns is slightly longer than the SF24G-TP (35 ns), but both parts meet the fast recovery classification of ≤ 500ns for currents > 200mA. Both parts are RoHS3 compliant and suitable for through-hole PCB mounting.

Q: What is the difference between EGP20D-E3/73 and EGP20D-E3/54?

A: Both parts are manufactured by Vishay and carry identical electrical specifications. The designation suffix (-E3/73 versus -E3/54) indicates different tape and reel packaging configurations for automated assembly. Electrical performance and package form factor (DO-15) are identical. Selection between these parts depends on assembly equipment compatibility and supplier availability.

Q: Why is EGP20D marked as "Not For New Designs"?

A: EGP20D carries a product status of "Not For New Designs," indicating that the manufacturer recommends using alternative parts for new circuit development. However, this part remains available for legacy system support and repair. For new designs, EGP20D-E3/73 or EGP20D-E3/54 are the recommended alternatives.

Q: Can MUR220RLG be used in place of SF24G-TP?

A: MUR220RLG is electrically equivalent but uses an axial (DO-41) package instead of the DO-15 package. Substitution is possible only if the PCB layout and mechanical mounting accommodate axial lead geometry. The electrical performance is identical, with the exception of lower reverse leakage current (2 µA versus 5 µA @ 200 V) and extended operating temperature range (-65 to 175°C versus -65 to 150°C).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (MUR220RLG, EGP20D, EGP20D-E3/54, and EGP20D-E3/73) are RoHS3 compliant and carry identical REACH status ("REACH Unaffected") as the SF24G-TP.

Q: What is the significance of the reverse recovery time difference between SF24G-TP (35 ns) and EGP20D variants (50 ns)?

A: Both parts are classified as fast recovery diodes with reverse recovery time ≤ 500ns for currents > 200mA. The 15 ns difference falls within the fast recovery classification and does not affect functional equivalence for general-purpose rectification applications. Applications with specific switching frequency or EMI requirements should evaluate the impact of this parameter on circuit performance.

Q: What is the MSL (Moisture Sensitivity Level) rating for substitute parts?

A: EGP20D-E3/73 and EGP20D-E3/54 carry MSL rating of 1 (Unlimited), matching the SF24G-TP. EGP20D carries "Not Applicable" MSL rating. MUR220RLG carries "Not Applicable" MSL rating. MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions for storage and handling.
