EGP30F Equivalent & Substitute Parts

Part Overview

The EGP30F is a general-purpose rectifier diode manufactured by onsemi, rated for 300 V DC reverse voltage and 3 A average rectified current in a DO-201AD axial through-hole package. This component is classified as "Not For New Designs," indicating it has been superseded in onsemi's product portfolio. Applications requiring this diode specification necessitate identification of functionally equivalent alternatives from active product lines to ensure long-term supply chain reliability and design continuity.

Substitute Part Grouping Explanation

Substitution of the EGP30F is determined by the following critical electrical and mechanical parameters:

Mandatory Matching Criteria:

Voltage - DC Reverse (Vr) (Max): 300 V
Current - Average Rectified (Io): 3 A
Mounting Type: Through Hole
RoHS Compliance: ROHS3 Compliant

Acceptable Variation Parameters:

Voltage - Forward (Vf): Substitute parts may vary within the range of 950 mV to 1.5 V at rated current
Reverse Recovery Time (trr): Substitute parts may range from 50 ns to 200 ns
Current - Reverse Leakage: Substitute parts may range from 1 µA to 10 µA at 300 V
Package / Case: DO-201AD (preferred for direct mechanical compatibility), DO-27, or SOD-64 (alternative axial packages)
Operating Temperature - Junction: Minimum -55°C acceptable; maximum 150°C or higher acceptable

Substitute parts are grouped into two categories: (1) DO-201AD package variants providing direct mechanical interchange, and (2) alternative axial packages (DO-27, SOD-64) providing electrical equivalence with different form factors.

Engineering Selection Recommendations

DO-201AD Package Substitutes (Direct Mechanical Compatibility):

The HER304G-TP and HER304G-AP from Micro Commercial Co provide the closest electrical and mechanical equivalence to the EGP30F. Both parts maintain 300 V / 3 A ratings, DO-201AD axial packaging, and fast recovery characteristics (50 ns trr). The HER304G variants feature lower forward voltage (950 mV @ 3 A) compared to the EGP30F (1.25 V @ 3 A), resulting in reduced power dissipation. Both are Active products with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

The 1N5403-E3/54 from Vishay General Semiconductor is an Active alternative in DO-201AD packaging with equivalent electrical ratings (1.2 V @ 3 A forward voltage). This part employs standard recovery technology rather than fast recovery, making it suitable for applications where switching speed is not critical.

Alternative Package Substitutes (Electrical Equivalence):

The HER304GA-G and HER304GT-G from Comchip Technology provide electrical equivalence in DO-27 axial packaging. These parts maintain 300 V / 3 A ratings with 50 ns reverse recovery time and 1 V forward voltage @ 3 A. DO-27 packaging is mechanically distinct from DO-201AD but remains through-hole compatible with appropriate PCB layout modifications.

The BYW73-TAP, BYW73-TR, SF5403-TAP, BYW172F-TAP, and BYW172F-TR from Vishay General Semiconductor provide electrical equivalence in SOD-64 axial packaging. These parts maintain 300 V / 3 A ratings with fast recovery characteristics. The BYW73 variants feature 1.1 V forward voltage @ 3 A and 200 ns reverse recovery time. The SF5403-TAP offers 1.1 V forward voltage @ 3 A with 50 ns reverse recovery time, matching the EGP30F's speed performance. The BYW172F variants feature avalanche technology with 100 ns reverse recovery time.

All substitute parts listed are Active products with ROHS3 compliance and REACH Unaffected status, ensuring regulatory compliance and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the HER304G-TP directly replace the EGP30F without PCB modifications?

A: Yes. The HER304G-TP maintains identical DO-201AD axial packaging, 300 V / 3 A electrical ratings, and through-hole mounting. No PCB layout changes are required for direct mechanical and electrical substitution.

Q: What is the difference between DO-201AD and DO-27 packages?

A: Both are axial through-hole packages with different physical dimensions. DO-201AD is the larger package used by the EGP30F. DO-27 is a smaller axial package used by HER304GA-G and HER304GT-G. PCB hole spacing and lead length differ between these packages, requiring layout verification before substitution.

Q: Why do some substitute parts have different forward voltage specifications?

A: Forward voltage varies based on semiconductor material composition and die design. The HER304G variants (950 mV @ 3 A) exhibit lower forward voltage than the EGP30F (1.25 V @ 3 A), resulting in lower power dissipation and heat generation. This difference is within acceptable operating parameters for general-purpose rectification applications.

Q: What is the significance of reverse recovery time (trr) differences?

A: Reverse recovery time affects switching speed and electromagnetic interference characteristics. The EGP30F specifies 50 ns trr (fast recovery). Substitute parts range from 50 ns (HER304G, HER304GA-G, SF5403-TAP) to 200 ns (BYW73 variants). Fast recovery devices (≤ 500 ns) are suitable for the EGP30F's application space. Standard recovery devices (> 500 ns) are not included in this substitute list.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What packaging options are available for the EGP30F substitutes?

A: Substitute parts are available in three axial through-hole packages: DO-201AD (HER304G-TP, HER304G-AP, 1N5403-E3/54), DO-27 (HER304GA-G, HER304GT-G), and SOD-64 (BYW73-TAP, BYW73-TR, BYW172F-TAP, BYW172F-TR, SF5403-TAP). Package selection depends on PCB layout constraints and mechanical compatibility requirements.

Q: Can I use a SOD-64 package substitute in place of the DO-201AD EGP30F?

A: SOD-64 substitutes provide electrical equivalence but differ in physical dimensions and lead spacing. PCB layout modifications are required. Verify hole spacing, lead length, and component placement before substitution.

Q: What is the difference between Tape & Box (TB) and Tape & Reel (TR) packaging?

A: TB and TR refer to supply packaging formats for manufacturing. TB packages components in tape with a box, while TR packages components on continuous reel tape. Both formats contain identical electronic components. Selection depends on manufacturing equipment and volume requirements.

Q: Why is the EGP30F marked "Not For New Designs"?

A: This status indicates onsemi has discontinued active development and recommends alternative parts for new applications. Existing inventory remains available, but long-term supply is not guaranteed. Substitution to Active products ensures design continuity and supply chain reliability.

Q: Are there performance differences between manufacturers' 300 V / 3 A diodes?

A: All substitute parts meet the 300 V / 3 A electrical specification. Differences exist in forward voltage, reverse recovery time, and reverse leakage current. These variations are within acceptable ranges for general-purpose rectification. Application-specific requirements (switching frequency, thermal management, EMI sensitivity) determine optimal part selection.
