Engineering Selection Recommendations

Primary Substitutes (Preferred for Direct Replacement):

The 1N5401-E3/54 and 1N5401-E3/73 from Vishay General Semiconductor are the preferred substitutes. Both parts maintain identical electrical specifications to the 1N5401-TP (100 V, 3 A, DO-201AD package) with active product status and ROHS3 compliance. These parts are available in high inventory quantities (62,000 and 16,569 units respectively) and are suitable for direct pin-for-pin replacement in existing designs.

The 1N5401G from Good-Ark Semiconductor and 1N5401G-T from Diodes Incorporated are functionally equivalent alternatives in the same DO-201AD package with active product status and ROHS3 compliance. Both offer extended temperature ranges (-55°C to 150°C and -65°C to 150°C respectively) and high inventory availability.

Secondary Substitutes (Package Alternatives):

The HER302GA-G and HER302GT-G from Comchip Technology provide electrical equivalence with a DO-27 package variant. These parts maintain 100 V, 3 A specifications with fast recovery characteristics and active product status. The DO-27 package is mechanically compatible with DO-201AD applications in through-hole mounting configurations.

Limited Substitutes (Current Derating Required):

The 1N5804 from Solid State Inc. operates at 2.5 A average rectified current, representing a 16.7% reduction from the 1N5401-TP specification. This part is suitable only for applications where the actual operating current does not exceed 2.5 A.

Not Recommended for New Designs:

The 1N5401RLG from onsemi carries a "Not For New Designs" status and exhibits higher reverse leakage current (10 µA versus 5 µA), making it unsuitable for new product development.

The 1N5186 and 1N5416 from Microchip Technology are RoHS non-compliant and do not meet current regulatory requirements for new applications.

Frequently Asked Questions (FAQ)

Q: Can I use HER302GA-G or HER302GT-G as a direct replacement for 1N5401-TP?

A: The HER302GA-G and HER302GT-G are electrically equivalent (100 V, 3 A) but use a DO-27 package instead of DO-201AD. Both packages are axial through-hole configurations with compatible pin spacing for most PCB layouts. Verify physical clearance and lead length requirements for your specific application before substitution.

Q: What is the difference between 1N5401-E3/54 and 1N5401-E3/73?

A: Both parts are manufactured by Vishay General Semiconductor with identical electrical specifications (100 V, 3 A, DO-201AD). The designations E3/54 and E3/73 indicate different tape and reel configurations for automated assembly. Electrical performance and compatibility are equivalent; selection depends on packaging and handling requirements.

Q: Why is 1N5401RLG listed as "Not For New Designs"?

A: The 1N5401RLG carries a "Not For New Designs" product status from onsemi. Additionally, this part exhibits reverse leakage current of 10 µA at 100 V, compared to 5 µA for the 1N5401-TP. New product designs should utilize active-status alternatives such as 1N5401-E3/54, 1N5401G, or 1N5401G-T.

Q: Can I use 1N5804 in place of 1N5401-TP?

A: The 1N5804 is rated for 2.5 A average rectified current, which is 0.5 A lower than the 1N5401-TP specification. Substitution is permissible only if your application's actual operating current does not exceed 2.5 A. Verify circuit requirements before implementation.

Q: Are there RoHS compliance differences between substitute options?

A: The 1N5401-TP, HER302GA-G, HER302GT-G, 1N5401-E3/54, 1N5401-E3/73, 1N5401G, 1N5401G-T, 1N5401RLG, and 1N5804 are all ROHS3 compliant. The 1N5186 and 1N5416 from Microchip Technology are RoHS non-compliant and should not be used in applications requiring RoHS certification.

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

A: The 1N5401-TP exhibits standard recovery characteristics (>500 ns). Substitute parts HER302GA-G, HER302GT-G, 1N5186, 1N5416, and 1N5804 feature fast recovery (≤500 ns). Fast recovery diodes reduce switching losses and are suitable for higher-frequency applications. Standard recovery diodes are appropriate for line-frequency and low-frequency rectification circuits.

Q: Can I substitute a part with a different operating temperature range?

A: The 1N5401-TP operates from -55°C to 150°C. Substitute parts with extended ranges (such as 1N5401G-T at -65°C to 150°C or 1N5186 at -65°C to 175°C) are compatible for applications within the original temperature specification. Parts with narrower ranges (such as 1N5401-E3/54 at -50°C to 150°C) are acceptable if your application does not require operation below -50°C.
