EGP20F Equivalent & Substitute Parts

Part Overview

The EGP20F is a general-purpose rectifier diode manufactured by onsemi, rated for 300 V DC reverse voltage and 2 A average rectified current in a DO-15 axial through-hole package. This device features fast recovery characteristics with a 50 ns reverse recovery time and operates across a junction temperature range of -65°C to 150°C. The EGP20F is classified as "Not For New Designs," indicating it is an established product no longer recommended for new circuit development. Identification of equivalent and substitute parts is necessary for applications requiring continued support, legacy system maintenance, or when the primary part becomes unavailable from inventory.

Substitute Part Grouping Explanation

Substitute parts for the EGP20F are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalent (Packaging Variant): Parts that maintain identical electrical specifications and the same base product number (EGP20) but differ only in packaging format (Cut Tape versus Tape & Reel). These parts satisfy all critical parameters: 300 V reverse voltage, 2 A average rectified current, 1.25 V forward voltage at 2 A, 50 ns reverse recovery time, and 5 µA reverse leakage current at 300 V.

Similar Substitutes (Package or Performance Variant): Parts that maintain the 300 V reverse voltage and 2 A current rating but differ in one or more of the following: package type (DO-15 versus SOD-57 versus DO-201AD), technology classification (Standard versus Avalanche), forward voltage characteristics, reverse recovery time, or operating temperature range. These parts are suitable for applications where package form factor or specific performance characteristics are not critical constraints.

Key Parameters Determining Substitution:

Voltage - DC Reverse (Vr) (Max): 300 V (mandatory match)
Current - Average Rectified (Io): 2 A (mandatory match for direct equivalents; 1.9 A or 3 A acceptable for similar substitutes depending on application requirements)
Reverse Recovery Time (trr): 50 ns (direct equivalents); 200 ns acceptable for similar substitutes
Package / Case: DO-15 (direct equivalents); SOD-57 or DO-201AD acceptable for similar substitutes with mechanical redesign
Technology: Standard (direct equivalents); Avalanche acceptable for similar substitutes with different forward voltage characteristics
RoHS Status: ROHS3 Compliant (all parts)

Engineering Selection Recommendations

Direct Equivalent Selection: The EGP20F-E3/54 (Vishay General Semiconductor - Diodes Division) is the primary direct equivalent. This part maintains identical electrical specifications across all critical parameters: 300 V reverse voltage, 2 A average rectified current, 1.25 V forward voltage at 2 A, 50 ns reverse recovery time, and 5 µA reverse leakage current. The only difference is packaging format (Tape & Reel versus Cut Tape). The EGP20F-E3/54 carries Active product status and ROHS3 compliance, making it suitable for continued production support. The operating temperature range is identical (-65°C to 150°C).

Alternative Selections with Package Compatibility: The HER204G-AP and HER204G-TP (Micro Commercial Co) maintain the DO-15 package form factor and are electrically compatible with the EGP20F. These parts feature identical 300 V reverse voltage and 2 A current ratings, with 50 ns reverse recovery time and 5 µA reverse leakage current. The forward voltage is lower (1 V @ 2 A versus 1.25 V @ 2 A), which represents improved performance. Both parts carry Active product status and ROHS3 compliance. The operating temperature range is -55°C to 150°C, which is narrower at the lower end but sufficient for most applications.

Alternative Selections with Package Redesign: The BYT53F-TAP, BYT53F-TR, BYW33-TAP, and BYW33-TR (Vishay General Semiconductor - Diodes Division) are suitable substitutes when package form factor can be modified. These parts maintain the 300 V reverse voltage rating and feature Avalanche technology with improved reverse voltage protection. The BYT53F variants provide 1.9 A current rating with 50 ns reverse recovery time, while the BYW33 variants provide 2 A current rating with 200 ns reverse recovery time. All carry Active product status, ROHS3 compliance, and extended operating temperature ranges (-55°C to 175°C). The SOD-57 package requires mechanical redesign of the circuit board layout.

Higher Current Alternative: The UF5403-E3/54 (Vishay General Semiconductor - Diodes Division) provides 3 A average rectified current in a DO-201AD package, offering increased current capacity for applications requiring higher current handling. This part maintains 300 V reverse voltage, 50 ns reverse recovery time, and ROHS3 compliance. The forward voltage is 1 V @ 3 A. The DO-201AD package is larger than DO-15 and requires mechanical redesign. This option is suitable when current margin is required.

Frequently Asked Questions (FAQ)

Q: Can the EGP20F-E3/54 be used as a direct replacement for the EGP20F?

A: Yes. The EGP20F-E3/54 is a direct electrical equivalent with identical specifications for voltage, current, forward voltage, reverse recovery time, and reverse leakage current. The only difference is packaging format (Tape & Reel versus Cut Tape). Both parts share the same base product number (EGP20) and DO-15 package form factor. The EGP20F-E3/54 carries Active product status, making it the recommended choice for continued production.

Q: What is the difference between the HER204G-AP and HER204G-TP variants?

A: Both parts are electrically identical with 300 V reverse voltage, 2 A current rating, 50 ns reverse recovery time, and 5 µA reverse leakage current. The difference is packaging format: HER204G-AP is supplied in Tape & Box format, while HER204G-TP is supplied in Tape & Reel format. Both maintain the DO-15 package form factor and are compatible with the EGP20F circuit board layout.

Q: Why do the BYT53F and BYW33 parts have different reverse recovery times?

A: The BYT53F variants feature 50 ns reverse recovery time, matching the EGP20F specification. The BYW33 variants feature 200 ns reverse recovery time due to their Avalanche technology design. The longer recovery time may affect switching performance in high-frequency applications. Selection between these variants depends on circuit timing requirements.

Q: Can I use the BYT53F-TR or BYW33-TR in place of the EGP20F without modifying the circuit board?

A: No. The BYT53F and BYW33 parts use the SOD-57 package, which has a different physical form factor than the DO-15 package used by the EGP20F. Circuit board layout modification is required to accommodate the different lead spacing and body dimensions. The electrical specifications are compatible, but mechanical redesign is necessary.

Q: What is the advantage of using the UF5403-E3/54 over the EGP20F?

A: The UF5403-E3/54 provides 3 A average rectified current compared to the EGP20F's 2 A rating, offering 50% additional current capacity. This provides design margin for applications approaching the 2 A limit. The trade-off is a larger DO-201AD package requiring circuit board redesign. The electrical specifications for voltage, forward voltage, and reverse recovery time are compatible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the EGP20F's compliance status. All parts are also REACH Unaffected and carry EAR99 ECCN classification.

Q: What is the operating temperature difference between the EGP20F and the substitute parts?

A: The EGP20F operates from -65°C to 150°C. The HER204G variants operate from -55°C to 150°C, providing a narrower lower temperature range. The BYT53F, BYW33, and UF5403 variants operate from -55°C to 175°C, providing extended upper temperature capability. Selection depends on the application's thermal environment requirements.

Q: Can I mix different substitute parts in the same circuit?

A: Yes, provided all parts meet the circuit's electrical requirements for voltage, current, and switching speed. However, using multiple part numbers increases inventory complexity and supply chain management overhead. Standardizing on a single substitute part is recommended for production consistency.

Q: Why is the EGP20F marked as "Not For New Designs"?

A: The "Not For New Designs" status indicates that onsemi no longer recommends this part for new circuit development. This classification typically reflects product maturity, availability of improved alternatives, or manufacturer discontinuation planning. For new designs, the EGP20F-E3/54 or HER204G variants are recommended as active alternatives.
