EGP30G-TP Equivalent & Substitute Parts

Part Overview

The EGP30G-TP is a general-purpose rectifier diode rated for 400 V DC reverse voltage and 3 A average rectified current in a DO-201AE axial through-hole 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 and ongoing production requirements. Substitute parts maintain the core electrical specifications while offering active product status and improved availability.

Engineering Selection Recommendations

Primary Substitutes (Preferred for New Designs):

1N5404-E3/54 and 1N5404-E3/73 from Vishay General Semiconductor are recommended as primary substitutes. Both parts maintain the 400 V / 3 A electrical specifications, feature active product status, and are ROHS3 compliant. The DO-201AD package is mechanically compatible with DO-201AE applications. These parts are available in high inventory quantities.

GP30G-E3/54 from Vishay General Semiconductor (SUPERECTIFIER® series) is an alternative primary substitute with active status, ROHS3 compliance, and extended operating temperature range (-65°C ~ 175°C). This part offers lower forward voltage (1.1 V @ 3 A) compared to the original specification.

Secondary Substitutes (Active Status, Package Considerations):

1N5404-G from Comchip Technology maintains 400 V / 3 A ratings with active product status and ROHS3 compliance. The DO-201AD package is compatible with through-hole applications. Forward voltage is lower at 950 mV @ 3 A.

MR854G from onsemi provides fast recovery characteristics (300 ns trr) matching the original EGP30G-TP recovery speed profile. Active product status and ROHS3 compliance are confirmed. Package compatibility is maintained through DO-201AA / DO-27 axial configuration.

Alternative Substitutes (Specialized Applications):

1N5418-TAP and 1N5625-TAP from Vishay General Semiconductor are avalanche-rated diodes with 400 V / 3 A specifications and active product status. These parts feature SOD-64 axial packaging and are suitable for applications requiring avalanche protection. Fast recovery (1N5418-TAP) and standard recovery (1N5625-TAP) options are available.

MUR440-E3/54 from Vishay General Semiconductor is rated for 400 V / 4 A, providing higher current capacity than the original 3 A specification. Fast recovery characteristics (75 ns trr) and active product status are confirmed. This part is suitable for applications requiring current margin.

Not Recommended for New Designs:

1N5404G and 1N5404RLG from onsemi carry "Not For New Designs" product status designation. While electrically compatible, these parts should not be selected for new product development.

All recommended substitutes are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I directly replace EGP30G-TP with 1N5404-E3/54?

A: Yes. Both parts maintain 400 V reverse voltage and 3 A average rectified current specifications. The DO-201AD package used in 1N5404-E3/54 is mechanically compatible with DO-201AE applications in through-hole mounting. The primary difference is recovery speed classification: EGP30G-TP is fast recovery (50 ns), while 1N5404-E3/54 is standard recovery (>500ns). This difference is acceptable in most general-purpose rectification applications.

Q: What is the difference between fast recovery and standard recovery diodes?

A: Recovery speed refers to the reverse recovery time (trr), which is the time required for a diode to stop conducting when reverse bias is applied. Fast recovery diodes (≤500ns) are suitable for high-frequency switching applications and power supplies. Standard recovery diodes (>500ns) are appropriate for line-frequency rectification and general-purpose applications. The EGP30G-TP specifies 50 ns fast recovery, but substitutes with standard recovery characteristics are acceptable for most applications unless high-frequency switching is required.

Q: Are DO-201AE and DO-201AD packages interchangeable?

A: DO-201AE and DO-201AD are both axial through-hole packages with similar physical dimensions and lead configurations. They are mechanically and electrically interchangeable in through-hole PCB applications. The primary difference is manufacturing specification detail; both are suitable for the same mounting and soldering processes.

Q: Can I use MUR440-E3/54 as a substitute if it is rated for 4 A instead of 3 A?

A: Yes. MUR440-E3/54 is rated for 400 V / 4 A, which exceeds the original 3 A specification. Higher current rating provides additional design margin and does not create compatibility issues. The part is suitable for direct replacement in applications designed for 3 A operation. Forward voltage specification (1.28 V @ 4 A) is comparable to the original (1.25 V @ 3 A).

Q: Why are some substitutes listed as "Not For New Designs"?

A: Parts designated "Not For New Designs" are in mature or declining production phases. While electrically functional and available in inventory, manufacturers recommend using active-status alternatives for new product development to ensure long-term supply continuity and support. For legacy system maintenance, these parts remain acceptable.

Q: What is the significance of ROHS3 compliance?

A: ROHS3 (Restriction of Hazardous Substances Directive 3) compliance indicates the part meets European Union environmental regulations restricting hazardous substances including lead, cadmium, and mercury. All listed substitute parts are ROHS3 compliant, ensuring compatibility with current manufacturing standards and regulatory requirements.

Q: Can I use 1N5418-TAP or 1N5625-TAP in place of EGP30G-TP?

A: Yes, with package consideration. Both parts maintain 400 V / 3 A specifications and are active products. However, they use SOD-64 axial packaging instead of DO-201AE. SOD-64 is a smaller axial package suitable for through-hole mounting. Verify PCB layout compatibility before substitution. 1N5418-TAP provides fast recovery (100 ns), while 1N5625-TAP provides standard recovery (7.5 µs).

Q: What does "Reverse Leakage Current" mean, and why does it vary among substitutes?

A: Reverse leakage current is the small current that flows through a diode when reverse bias is applied. Lower leakage current indicates better diode quality and lower power dissipation in reverse bias conditions. The EGP30G-TP specifies 5 µA @ 400 V. Substitutes range from 1 µA to 10 µA at their respective voltage ratings. Variation within this range is acceptable for general-purpose rectification applications.

Q: Is GP30G-E3/54 (SUPERECTIFIER® series) better than standard 1N5404 substitutes?

A: GP30G-E3/54 offers lower forward voltage (1.1 V @ 3 A) compared to standard 1N5404 variants (1.2 V @ 3 A), resulting in reduced power dissipation and improved efficiency. Extended operating temperature range (-65°C ~ 175°C) provides additional thermal margin. These characteristics make it suitable for applications where efficiency and thermal performance are priorities. For general-purpose applications, standard 1N5404 variants are functionally equivalent.
