EGP20B Equivalent & Substitute Parts

Part Overview

The EGP20B is a general-purpose rectifier diode rated for 100 V DC reverse voltage and 2 A average rectified current in a DO-15 through-hole package. Manufactured by onsemi, this component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent and substitute parts is necessary for applications requiring continued supply, design updates, or component availability optimization.

Substitute Part Grouping Explanation

Substitution of the EGP20B is determined by matching the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 100 V minimum
Current - Average Rectified (Io): 2 A minimum
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Reverse Recovery Time (trr): 50 ns or lower
Package / Case: DO-15 or DO-204AC (axial through-hole)
Mounting Type: Through Hole

Direct Equivalents maintain all electrical specifications and package compatibility. These parts are pin-for-pin and functionally interchangeable without circuit modification.

Similar Substitutes meet the core voltage and current requirements but may differ in secondary parameters such as forward voltage, reverse recovery time, capacitance, or temperature range. These require circuit-level evaluation to confirm suitability.

Limited Substitutes satisfy voltage and current ratings but operate outside the fast recovery speed classification or use alternative package formats (SOD-57, DO-201AD). These are suitable only when application requirements permit relaxed speed performance or mechanical redesign.

Engineering Selection Recommendations

Direct Equivalent (Recommended for Replacement):

EGP20B-E3/54 (Vishay General Semiconductor) is the primary direct equivalent. This part maintains identical electrical specifications (100 V, 2 A, 50 ns reverse recovery time, fast recovery speed) and compatible package format (DO-204AC, which is equivalent to DO-15). The part is in Active product status, ensuring continued availability and supply chain stability. RoHS3 compliance and REACH unaffected status match the original component.

Active Substitutes with Full Compatibility:

HER202G A0G (Taiwan Semiconductor Corporation) provides equivalent performance with 100 V, 2 A ratings, 50 ns reverse recovery time, and fast recovery speed classification. Package compatibility is confirmed (DO-204AC/DO-15). This part is in Active status with matching compliance certifications.

Substitutes with Parameter Deviations:

FR202GP-AP (Micro Commercial Co) meets voltage and current requirements (100 V, 2 A) but exhibits extended reverse recovery time (150 ns versus 50 ns). This part is suitable for applications where switching speed is not performance-critical. Package format is DO-15 (compatible).

GPP20B-E3/54 (Vishay General Semiconductor) operates at 100 V and 2 A but uses standard recovery speed classification (>500 ns) rather than fast recovery. This part is appropriate for low-frequency rectification applications where recovery speed does not impact circuit performance.

Limited Substitutes (Voltage or Current Derating Required):

BYT53B-TAP and BYT53B-TR (Vishay General Semiconductor) are avalanche diodes rated for 100 V and 1.9 A. Current rating is 50 mA below the original specification. These parts use SOD-57 package format, requiring mechanical redesign. Suitable only when avalanche protection is required and current derating is acceptable.

Not Recommended for Direct Substitution:

FR207GP-AP and FR207GP-TP (Micro Commercial Co) are rated for 1000 V reverse voltage, exceeding application requirements. Extended reverse recovery time (500 ns) indicates slower switching performance. These parts are suitable only for high-voltage applications.

STTH302 and STTH302RL (STMicroelectronics) are rated for 200 V and 3 A, exceeding the original 100 V, 2 A specification. DO-201AD package format differs from DO-15. These parts are suitable for higher-voltage, higher-current applications requiring mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can EGP20B-E3/54 be used as a direct replacement for EGP20B?

A: Yes. EGP20B-E3/54 is a direct equivalent with identical electrical specifications (100 V, 2 A, 50 ns reverse recovery time) and compatible package format (DO-204AC is equivalent to DO-15). No circuit modification is required.

Q: What is the difference between DO-15 and DO-204AC packages?

A: DO-15 and DO-204AC are equivalent designations for the same axial through-hole package format. Both refer to a cylindrical component with leads at each end, suitable for insertion into standard PCB holes.

Q: Can FR202GP-AP replace EGP20B in all applications?

A: FR202GP-AP meets the 100 V and 2 A requirements but has a reverse recovery time of 150 ns compared to EGP20B's 50 ns. This part is suitable for low-frequency rectification. For high-frequency switching applications, the extended recovery time may degrade performance.

Q: Why is BYT53B-TAP listed as a substitute if the current rating is lower?

A: BYT53B-TAP is listed as a similar substitute because it meets the 100 V voltage requirement and maintains fast recovery speed (50 ns). However, the 1.9 A current rating is 50 mA below the original 2 A specification. This part is suitable only for applications where the actual operating current does not exceed 1.9 A.

Q: What does "Product Status: Not For New Designs" mean for EGP20B?

A: This designation indicates that EGP20B has reached end-of-life status and onsemi no longer recommends its use in new circuit designs. Existing inventory may remain available, but long-term supply is not guaranteed. Transitioning to an active substitute such as EGP20B-E3/54 is recommended for new designs and future production.

Q: Are STTH302 and STTH302RL suitable replacements?

A: STTH302 and STTH302RL exceed the original specifications (200 V, 3 A versus 100 V, 2 A) and use a different package format (DO-201AD versus DO-15). These parts are not direct replacements and require circuit and mechanical redesign. They are suitable only for applications requiring higher voltage or current ratings.

Q: What is the significance of "Fast Recovery ≤ 500ns, > 200mA (Io)" speed classification?

A: This classification indicates that the diode exhibits fast recovery characteristics with reverse recovery time of 500 ns or less when conducting currents exceeding 200 mA. EGP20B achieves 50 ns reverse recovery time, making it suitable for high-frequency switching applications. Substitutes with standard recovery speed (>500 ns) are limited to low-frequency rectification.

Q: Can GPP20B-E3/54 be used in high-frequency switching circuits?

A: GPP20B-E3/54 uses standard recovery speed classification (>500 ns) rather than fast recovery. This part is not suitable for high-frequency switching applications where EGP20B's 50 ns recovery time is required. GPP20B-E3/54 is appropriate for low-frequency rectification only.

Q: What compliance certifications should I verify when selecting a substitute?

A: Verify that the substitute part maintains RoHS3 compliance and REACH unaffected status to ensure regulatory alignment with the original EGP20B. All listed substitutes meet these requirements.

Q: Is packaging (Cut Tape versus Tape & Reel) significant for substitution?

A: Packaging format (Cut Tape, Tape & Reel, Tape & Box) affects supply chain logistics and handling but does not impact electrical or mechanical compatibility. The same part number with different packaging designations (e.g., FR207GP-AP versus FR207GP-TP) are functionally identical and interchangeable.
