EGP20A-TP Equivalent & Substitute Parts

Part Overview

The EGP20A-TP is a general-purpose rectifier diode rated for 50 V DC reverse voltage and 2 A average rectified current in a through-hole DO-15 package. Manufactured by Micro Commercial Co, this component is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for new designs, production continuity, and long-term component availability.

Substitute Part Grouping Explanation

Substitute parts for the EGP20A-TP are classified into three categories based on electrical and mechanical compatibility:

Upgrade Substitutes maintain identical electrical specifications (50 V, 2 A) with active product status and enhanced temperature ranges. These parts are direct functional replacements with improved availability and compliance certifications.

Similar Substitutes share the same voltage rating (50 V) and package type (DO-15/DO-204AC) but differ in current rating (1.5 A instead of 2 A) or voltage rating (100 V instead of 50 V). These parts are suitable when the application can tolerate reduced current capacity or higher voltage margin.

Parametric Equivalents match all critical electrical parameters (50 V, 2 A, fast recovery ≤ 500ns, 50 ns reverse recovery time) from alternative manufacturers, providing functional equivalence with active product status.

Substitution eligibility is determined by:

Voltage - DC Reverse (Vr) rating equal to or greater than 50 V
Current - Average Rectified (Io) rating equal to or greater than 2 A
Speed classification (Fast Recovery ≤ 500ns, > 200mA)
Reverse Recovery Time (trr) of 50 ns or less
Through-hole mounting in DO-15/DO-204AC package
Operating temperature range encompassing -55°C to 150°C minimum

Engineering Selection Recommendations

Primary Upgrade Substitutes (Direct Replacements)

EGP20A-E3/54 and EGP20A-E3/73 are the preferred upgrade substitutes. Both are manufactured by Vishay General Semiconductor and maintain identical electrical specifications to the EGP20A-TP: 50 V reverse voltage, 2 A average rectified current, 50 ns reverse recovery time, and fast recovery characteristics. Both parts are ROHS3 compliant and REACH unaffected. The extended junction temperature range (-65°C to 150°C) provides improved thermal margin compared to the original part. These parts are active products with high inventory availability (1031 and 924 units respectively).

Parametric Equivalent Substitute

HER201G from Taiwan Semiconductor Corporation provides complete electrical equivalence to the EGP20A-TP with identical voltage, current, forward voltage, and recovery time specifications. This part is active, ROHS3 compliant, and REACH unaffected. It is suitable for applications where manufacturer diversity is required or when Vishay parts are unavailable.

Current-Reduced Substitutes (1.5 A Rating)

GP15A-E3/54 and RGP15A-E3/54 are suitable only for applications where the circuit design can tolerate 1.5 A average rectified current instead of 2 A. Both maintain the 50 V voltage rating and through-hole DO-15 package. RGP15A-E3/54 offers fast recovery characteristics (≤ 500ns, 150 ns trr) compared to GP15A-E3/54 (standard recovery, 3.5 µs trr). Both are active products with extended temperature ranges (-65°C to 175°C).

Voltage-Elevated Substitute

EGP20B from Fairchild Semiconductor provides 100 V reverse voltage rating with identical 2 A current capacity and fast recovery characteristics. This part is suitable for applications requiring higher voltage margin or where 100 V rated components are specified. It maintains the DO-15 package and is ROHS3 compliant.

Enhanced Recovery Time Substitute

SBYV27-50-E3/73 from Vishay General Semiconductor maintains 50 V and 2 A specifications with superior reverse recovery time (15 ns versus 50 ns). This part is active and ROHS3 compliant, suitable for high-frequency switching applications requiring minimal recovery time.

Frequently Asked Questions (FAQ)

Q: Can EGP20A-E3/54 and EGP20A-E3/73 be used interchangeably with EGP20A-TP?

A: Yes. Both parts maintain identical electrical specifications (50 V, 2 A, 50 ns reverse recovery time, fast recovery ≤ 500ns) and through-hole DO-15 packaging. The primary differences are active product status, extended temperature range, and improved availability. The forward voltage is slightly lower (950 mV versus 1 V at 2 A), which is within acceptable tolerance for general-purpose rectifier applications.

Q: What is the difference between EGP20A-E3/54 and EGP20A-E3/73?

A: Both parts are electrically identical with the same voltage, current, and recovery specifications. The difference is in packaging format: EGP20A-E3/54 is supplied in Cut Tape (CT) format, while EGP20A-E3/73 is supplied in bulk format. Selection depends on procurement and assembly requirements.

Q: Can 1.5 A rated diodes (GP15A-E3/54, RGP15A-E3/54, 1N5391GP-E3/54) replace the 2 A EGP20A-TP?

A: These parts are suitable only if the application circuit design can operate with reduced current capacity. The 1.5 A rating represents a 25% reduction from the original 2 A specification. Circuit analysis must confirm that peak and average current demands do not exceed 1.5 A. These parts maintain the 50 V voltage rating and through-hole package compatibility.

Q: Is HER201G a suitable substitute for EGP20A-TP?

A: Yes. HER201G from Taiwan Semiconductor Corporation provides complete parametric equivalence: 50 V reverse voltage, 2 A average rectified current, 1 V forward voltage at 2 A, 50 ns reverse recovery time, and fast recovery characteristics. It is an active product with ROHS3 compliance and is suitable for applications requiring manufacturer diversity.

Q: Why is EGP20B (100 V rated) listed as a substitute for a 50 V part?

A: EGP20B maintains the 2 A current rating and fast recovery characteristics while providing a higher voltage margin (100 V versus 50 V). This part is suitable for applications where higher voltage rating is acceptable or required. The higher voltage rating does not degrade performance in 50 V circuits; it provides additional safety margin and component interchangeability across multiple voltage classes.

Q: What is the significance of reverse recovery time (trr) in selecting a substitute?

A: Reverse recovery time affects switching speed and efficiency in rectifier circuits. The EGP20A-TP specifies 50 ns. Substitutes with equal or lower trr (such as UG2A-E3/54 at 25 ns or SBYV27-50-E3/73 at 15 ns) provide improved high-frequency performance. Substitutes with higher trr (such as GP15A-E3/54 at 3.5 µs) are suitable only for low-frequency applications where switching speed is not critical.

Q: Are all listed substitutes ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the compliance status of the original EGP20A-TP. This ensures compatibility with environmental and regulatory requirements.

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

A: DO-15 and DO-204AC are equivalent designations for the same through-hole axial package. DO-204AC is the formal JEDEC designation, while DO-15 is the legacy designation. Parts specified as DO-204AC (DO-15) or DO-15 are mechanically and electrically interchangeable in through-hole applications.
