1N5401RL General Purpose Rectifier Diode Equivalent & Substitute Parts

Part Overview

The 1N5401RL is a general-purpose rectifier diode manufactured by onsemi, rated for 100 V DC reverse voltage and 3 A average rectified current in an axial through-hole package (DO-201AA/DO-27). The device features standard recovery characteristics with forward voltage of 1 V at 3 A and reverse leakage current of 10 µA at 100 V, operating across a junction temperature range of -65°C to 170°C.

The 1N5401RL is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity, ensure supply chain availability, and meet current manufacturing compliance standards including RoHS3 certification. Direct substitutes maintain identical electrical ratings while offering active product status and improved compliance profiles.

Frequently Asked Questions (FAQ)

Q1: Can the 1N5401RL be directly replaced with any of the listed substitute parts?

A: Yes, all listed substitute parts maintain the core electrical specifications (100 V reverse voltage, 3 A average rectified current) and through-hole axial package configuration. Direct mechanical and electrical compatibility is established. However, minor variations in forward voltage (1.0 V to 1.2 V @ 3 A) and reverse leakage current (5 µA to 10 µA @ 100 V) exist and remain within acceptable engineering tolerances for general-purpose rectification applications.

Q2: What is the difference between the 1N5401RL and 1N5401RLG?

A: Both parts are manufactured by onsemi and share identical electrical specifications. The primary differences are: (1) 1N5401RLG is classified as "Not For New Designs" versus "Obsolete" for 1N5401RL; (2) 1N5401RLG is RoHS3 compliant while 1N5401RL is non-compliant; (3) 1N5401RLG has a maximum operating temperature of 150°C versus 170°C for 1N5401RL; (4) 1N5401RLG is supplied in Cut Tape (CT) packaging versus unspecified packaging for 1N5401RL.

Q3: Are there differences in recovery speed among the substitute parts?

A: Yes. Most substitute parts feature standard recovery characteristics (>500 ns). The EGP30B (Fairchild Semiconductor) is specified as fast recovery (≤500 ns) with a reverse recovery time of 50 ns. This difference affects switching performance in high-frequency applications. For applications sensitive to recovery time, verify circuit requirements before selecting EGP30B as a substitute.

Q4: Which substitute part has the best availability?

A: The 1N5401-E3/54 (Vishay General Semiconductor - Diodes Division) has the highest inventory level at 62,000 pieces in stock, followed by 1N5401G-T (Diodes Incorporated) with 65,060 pieces. Both parts are classified as Active and RoHS3 compliant, making them suitable for high-volume production applications.

Q5: What is the significance of the operating temperature range differences?

A: The 1N5401RL operates from -65°C to 170°C. Most substitute parts operate from -50°C to 150°C, representing a narrower range. The GP30B-E3/54 and GP30B-E3/73 extend the upper limit to 175°C, providing enhanced thermal performance. For applications operating at extreme temperatures, verify that the selected substitute part's temperature range meets system requirements.

Q6: Why do some parts show forward voltage specifications at different current levels?

A: Forward voltage is current-dependent. Most parts specify Vf @ 3 A (matching the rated average rectified current). The GI501-E3/54 and GI501-E3/73 specify Vf @ 9.4 A, indicating characterization at a higher current level. This does not affect substitution compatibility; the parts remain electrically equivalent at the rated 3 A operating point.

Q7: What does "RoHS3 Compliant" mean for component selection?

A: RoHS3 (Restriction of Hazardous Substances Directive 3) compliance indicates that the component meets current European Union environmental standards, restricting the use of hazardous materials including lead, cadmium, and mercury. For applications subject to regulatory compliance or customer requirements, RoHS3-compliant parts (all listed substitutes except EGP30B) are required. The original 1N5401RL is RoHS non-compliant.

Q8: Can the 1N5401RL be used in new product designs?

A: No. The 1N5401RL is classified as obsolete. For new product designs, select from parts with Active status: 1N5401G-T, 1N5401G, 1N5401-E3/54, GI501-E3/54, GI501-E3/73, GP30B-E3/54, GP30B-E3/73, EGP30B, or P300B-E3/54. These parts offer active manufacturer support, current compliance certifications, and assured long-term availability.

Q9: What packaging options are available for the substitute parts?

A: Substitute parts are supplied in multiple packaging formats: Cut Tape (CT), Tape & Reel (TR), and Bulk. Cut Tape and Tape & Reel formats are suitable for automated assembly processes. Bulk packaging is available for manual assembly or lower-volume applications. All parts maintain the DO-201AD or DO-201AA axial through-hole package configuration for mechanical compatibility.

Q10: Is the 1N5401G from Good-Ark Semiconductor equivalent to the 1N5401G-T from Diodes Incorporated?

A: Both parts share the same base designation (1N5401G) and maintain identical electrical ratings (100 V, 3 A). However, they are manufactured by different companies (Good-Ark Semiconductor versus Diodes Incorporated) and have minor specification differences: Good-Ark 1N5401G operates -55°C to 150°C with 1.1 V forward voltage; Diodes 1N5401G-T operates -65°C to 150°C with 1.1 V forward voltage. Both are functionally equivalent for general-purpose rectification. Selection should be based on supply chain availability and preferred manufacturer.
