1N5399-AP Equivalent & Substitute Parts

Part Overview

The 1N5399-AP is a general-purpose rectifier diode rated for 1000 V DC reverse voltage and 1.5 A average rectified current in a DO-15 axial through-hole package. Manufactured by Micro Commercial Co, this component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design support and procurement continuity. The 1N5399-AP remains in stock inventory but is no longer in active production status, making substitute identification critical for new designs and long-term supply chain planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N5399-AP is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 1.5 A
• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial
• Operating Temperature Range: -55°C to 150°C
• RoHS Compliance: ROHS3 Compliant

The 1N5399GP-AP qualifies as a direct substitute because it maintains identical ratings across all critical electrical parameters (reverse voltage, average rectified current, reverse leakage current, recovery speed) and mechanical specifications (through-hole mounting, DO-15 package, axial configuration). Both parts share the same base product number (1N5399) and comply with identical environmental and regulatory standards.

Parameter Comparison

Engineering Selection Recommendations

The 1N5399GP-AP is the qualified substitute for the 1N5399-AP based on the following engineering criteria:

Product Status: The 1N5399-AP is classified as obsolete, while the 1N5399GP-AP maintains active production status. For new designs and long-term supply chain assurance, the 1N5399GP-AP is the appropriate selection.

Electrical Equivalence: Both parts maintain identical maximum reverse voltage (1000 V), average rectified current (1.5 A), reverse leakage current (5 µA @ 1000 V), and recovery speed characteristics. The forward voltage specification of the 1N5399GP-AP (1.4 V @ 1.5 A) is slightly higher than the 1N5399-AP (1.1 V @ 1.5 A) but remains within acceptable rectifier diode tolerance ranges for general-purpose applications.

Mechanical and Regulatory Compliance: Both parts are packaged identically in DO-15 axial through-hole configuration, suitable for PCB mounting in equivalent footprints. Both maintain ROHS3 compliance and identical operating temperature ranges (-55°C to 150°C).

Packaging Availability: The 1N5399GP-AP is supplied in Tape & Box (TB) packaging with 670 units in current inventory, providing reliable procurement availability compared to the obsolete 1N5399-AP.

Frequently Asked Questions (FAQ)

Q: Can the 1N5399GP-AP be used as a direct replacement for the 1N5399-AP in existing designs?

A: Yes. The 1N5399GP-AP is electrically and mechanically equivalent to the 1N5399-AP. Both parts share identical reverse voltage (1000 V), average rectified current (1.5 A), reverse leakage current (5 µA), recovery speed, and DO-15 axial through-hole package configuration. The forward voltage difference (1.4 V versus 1.1 V) is within standard rectifier diode tolerance and does not affect functional compatibility in general-purpose rectification applications.

Q: Why is the 1N5399-AP classified as obsolete?

A: The 1N5399-AP has been discontinued by the manufacturer. The 1N5399GP-AP represents the active production equivalent, ensuring continued availability and supply chain support for this rectifier diode specification.

Q: Are there any differences in packaging between the 1N5399-AP and 1N5399GP-AP?

A: Both parts use identical DO-15 axial through-hole package configuration. The primary packaging difference is that the 1N5399GP-AP is supplied in Tape & Box (TB) format, which is standard for active production components. This packaging format does not affect electrical performance or PCB mounting compatibility.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by matching the following parameters: Voltage - DC Reverse (Vr) (Max) at 1000 V, Current - Average Rectified (Io) at 1.5 A, mounting type (Through Hole), package configuration (DO-15 Axial), and operating temperature range (-55°C to 150°C). The 1N5399GP-AP meets all these criteria.

Q: Is the 1N5399GP-AP RoHS compliant?

A: Yes. The 1N5399GP-AP is ROHS3 compliant, matching the compliance status of the 1N5399-AP. Both parts meet current environmental and regulatory requirements for electronic component manufacturing and use.
