1N5397-AP Equivalent & Substitute Parts

Part Overview

The 1N5397-AP is a general-purpose rectifier diode rated for 600 V DC reverse voltage and 1.5 A average rectified current in a DO-15 through-hole axial package. This part is classified as obsolete, which necessitates identification of active equivalent components for ongoing design support and procurement continuity. The 1N5397-AP maintains ROHS3 compliance and operates across a junction temperature range of -55°C to 150°C, making it suitable for standard industrial and consumer rectification applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N5397-AP is determined by electrical and mechanical parameter equivalence within the rectifier diode category. The primary substitution criteria are:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V minimum
• Current - Average Rectified (Io): 1.5 A minimum
• Reverse recovery speed: Standard Recovery classification
• Current - Reverse Leakage @ Vr: 5 µA maximum @ 600 V

Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial configuration
• Operating Temperature Range: -55°C to 150°C minimum

Compliance Parameters:

• RoHS Status: ROHS3 Compliant

The 1N5397GP-AP meets all substitution criteria as an active product from the same manufacturer with identical electrical ratings, package configuration, and compliance certifications. The transition from obsolete to active product status supports long-term component availability.

Parameter Comparison

Engineering Selection Recommendations

The 1N5397GP-AP is the direct substitute for the obsolete 1N5397-AP. Both components are manufactured by Micro Commercial Co and share identical electrical ratings, package configuration, and compliance certifications. The 1N5397GP-AP maintains active product status, ensuring continued availability and supply chain support.

The 1N5397GP-AP exhibits a forward voltage drop of 1.4 V at 1.5 A, which is 0.3 V higher than the 1N5397-AP specification of 1.1 V at the same current. This difference remains within acceptable rectifier diode performance variation and does not affect functional compatibility in standard rectification circuits. The capacitance specification of 15 pF in the 1N5397GP-AP is lower than the 20 pF of the 1N5397-AP, which represents an improvement in high-frequency switching characteristics.

Both parts comply with ROHS3 requirements and carry unlimited moisture sensitivity level (MSL 1) ratings, supporting deployment in standard manufacturing and storage environments without special handling protocols.

Frequently Asked Questions (FAQ)

Q: Can the 1N5397GP-AP directly replace the 1N5397-AP in existing designs?

A: Yes. The 1N5397GP-AP is electrically and mechanically equivalent to the 1N5397-AP. Both components share identical voltage ratings (600 V), current ratings (1.5 A), package configuration (DO-15 axial through-hole), and operating temperature range (-55°C to 150°C). The forward voltage difference of 0.3 V does not affect functional compatibility in standard rectification applications.

Q: What is the significance of the forward voltage difference between these parts?

A: The 1N5397-AP specifies a maximum forward voltage of 1.1 V at 1.5 A, while the 1N5397GP-AP specifies 1.4 V at the same current. This 0.3 V difference is typical variation within the rectifier diode product category and does not compromise circuit operation. Power dissipation increases proportionally with forward voltage; applications sensitive to thermal performance should calculate the specific impact for their operating conditions.

Q: Are there packaging differences between these parts?

A: Both parts use the DO-15 axial through-hole package. The 1N5397-AP is supplied in standard packaging, while the 1N5397GP-AP is supplied in Tape & Box (TB) format. The physical component dimensions and pin configuration are identical, ensuring direct mechanical compatibility in PCB layouts and breadboard applications.

Q: Why is the 1N5397-AP classified as obsolete?

A: The 1N5397-AP has reached end-of-life status with Micro Commercial Co. The 1N5397GP-AP represents the active continuation of this product line, offering identical electrical performance with improved supply chain availability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1N5397-AP and 1N5397GP-AP are ROHS3 compliant and carry ECCN EAR99 classification. Both parts have unlimited moisture sensitivity level (MSL 1) ratings, eliminating special storage or handling requirements.

Q: What is the capacitance specification difference, and does it matter?

A: The 1N5397-AP specifies 20 pF at 4 V and 1 MHz, while the 1N5397GP-AP specifies 15 pF at the same conditions. The lower capacitance in the 1N5397GP-AP represents improved performance in high-frequency switching applications. For standard 50/60 Hz rectification circuits, this difference has negligible impact.
