1N5400-AP General Purpose Rectifier Diode Equivalent & Substitute Parts

Part Overview

The 1N5400-AP is a general purpose rectifier diode manufactured by Micro Commercial Co, rated for 50 V DC reverse voltage and 3 A average rectified current in a DO-201AD axial through-hole package. This part is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and ongoing production requirements. Active alternatives with identical or compatible electrical and mechanical specifications are available from both the original manufacturer and qualified alternative suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N5400-AP is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 50 V minimum
• Current - Average Rectified (Io): 3 A minimum
• Package / Case: DO-201AD, Axial (mechanical compatibility)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Operating Temperature Range: Must encompass -55°C to 150°C junction temperature

Secondary Compatibility Factors:

• Voltage - Forward (Vf) (Max): Forward voltage drop must not exceed application requirements
• Current - Reverse Leakage @ Vr: Leakage current at rated reverse voltage
• RoHS Status: ROHS3 Compliant for regulatory compliance
• Moisture Sensitivity Level: MSL 1 for unlimited shelf life

Substitute parts meeting all primary criteria are electrically and mechanically interchangeable with the 1N5400-AP in standard rectification applications.

Engineering Selection Recommendations

1N5400GP-AP (Direct Substitute - Recommended Primary Choice)

The 1N5400GP-AP is the direct active equivalent from the original manufacturer, Micro Commercial Co. This part maintains identical electrical ratings (50 V, 3 A) and mechanical specifications (DO-201AD, Through Hole) as the obsolete 1N5400-AP. The primary difference is active product status with current manufacturing and availability. Forward voltage specification increases marginally from 1.0 V to 1.1 V at 3 A, which remains within standard rectifier application tolerances. ROHS3 compliance and MSL 1 rating are maintained. This substitute is the preferred selection for direct replacement in existing designs.

GI500-E3/54 (Alternative Substitute - Qualified Alternative)

The GI500-E3/54 from Vishay General Semiconductor - Diodes Division meets all primary substitution criteria with 50 V reverse voltage, 3 A average rectified current, and DO-201AD axial through-hole package. This part is active and ROHS3 compliant. The operating temperature range extends to -50°C minimum (versus -55°C for the main part), which is acceptable for most industrial applications. Forward voltage specification is 1.1 V @ 9.4 A. Packaging is supplied as Tape & Reel (TR), suitable for automated assembly environments. This substitute is qualified for applications where alternative manufacturer sourcing is required or preferred.

Both substitute parts satisfy regulatory compliance requirements and provide equivalent functional performance in standard rectification circuits.

Frequently Asked Questions (FAQ)

Q: Can the 1N5400GP-AP be used as a direct replacement for the 1N5400-AP?

A: Yes. The 1N5400GP-AP is electrically and mechanically equivalent to the 1N5400-AP. Both parts share identical voltage ratings (50 V), current ratings (3 A), package type (DO-201AD), and mounting configuration (Through Hole). The primary advantage of the 1N5400GP-AP is active product status and current availability.

Q: What is the difference between the 1N5400-AP and 1N5400GP-AP?

A: The 1N5400-AP is obsolete, while the 1N5400GP-AP is active. The forward voltage specification differs slightly: 1.0 V @ 3 A for the 1N5400-AP versus 1.1 V @ 3 A for the 1N5400GP-AP. This 0.1 V difference is negligible in standard rectification applications and does not affect circuit functionality.

Q: Is the GI500-E3/54 compatible with the 1N5400-AP?

A: Yes. The GI500-E3/54 meets all primary substitution criteria: 50 V reverse voltage, 3 A average rectified current, DO-201AD package, and through-hole mounting. The operating temperature minimum is -50°C instead of -55°C, which is acceptable for most applications. The primary difference is packaging format (Tape & Reel versus bulk).

Q: What does "DO-201AD" package mean?

A: DO-201AD is an axial through-hole package designation for diodes. The component has two leads extending axially from opposite ends of the cylindrical body. This package is mechanically compatible across all three parts listed and requires standard through-hole PCB assembly processes.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 1N5400-AP, 1N5400GP-AP, and GI500-E3/54 are all ROHS3 compliant, meeting environmental and regulatory requirements for lead-free manufacturing and restricted substance limitations.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture-related degradation. All three parts carry this rating, meaning they do not require special moisture-controlled storage or handling procedures and maintain full performance characteristics indefinitely under standard storage conditions.

Q: Can I use the GI500-E3/54 in automated assembly if my line uses bulk component feeders?

A: The GI500-E3/54 is supplied in Tape & Reel (TR) packaging, which is standard for automated pick-and-place assembly. If your assembly line requires bulk component feeders, the 1N5400GP-AP in bulk packaging is the appropriate selection.

Q: What is the reverse recovery time specification?

A: The 1N5400-AP and 1N5400GP-AP specify standard recovery >500 ns at >200 mA. The GI500-E3/54 provides additional specification: reverse recovery time (trr) of 2 µs. All three parts are classified as standard recovery diodes suitable for general purpose rectification applications.
