M5KP16AE3 Equivalent & Substitute Parts

Part Overview

The M5KP16AE3 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This component operates with a 16V reverse standoff voltage and provides 26V maximum clamping voltage with 192A peak pulse current capability. The device is housed in a DO-204AR axial through-hole package and is qualified to MIL-PRF-19500 military standards.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter ranges. The primary substitute identified for the M5KP16AE3 is the 5KP16A from Littelfuse Inc., which maintains identical voltage ratings and power dissipation characteristics while offering enhanced temperature operating range and RoHS3 compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M5KP16AE3 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Requirements:

• Voltage - Reverse Standoff (Typ): 16V (exact match)
• Voltage - Breakdown (Min): 17.8V (exact match)
• Voltage - Clamping (Max) @ Ipp: 26V (exact match)
• Current - Peak Pulse (10/1000µs): ≥192A
• Power - Peak Pulse: ≥5000W
• Unidirectional Channels: 1 (exact match)
• Type: Zener (exact match)

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole (exact match)
• Package Category: Axial (compatible package form factors)

Compliance Considerations:

• Product Status: Active (current production)
• RoHS and REACH compliance status documented

The 5KP16A from Littelfuse Inc. satisfies all electrical equivalence criteria with identical voltage ratings and power dissipation, while providing superior peak pulse current (196.2A versus 192A) and extended operating temperature range (-55°C to 175°C versus -65°C to 150°C).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 5KP16A (Littelfuse Inc.)

The 5KP16A is a direct electrical equivalent to the M5KP16AE3 with identical voltage ratings (16V standoff, 26V clamping) and power dissipation (5000W peak pulse). The substitute provides measurable advantages in peak pulse current specification (196.2A versus 192A) and operating temperature range (-55°C to 175°C versus -65°C to 150°C).

Selection of the 5KP16A is appropriate for applications where:

• Electrical performance equivalence is the primary requirement
• RoHS3 compliance is mandated or preferred
• Operating temperature range of -55°C to 175°C is acceptable
• Axial through-hole package form factor is compatible with PCB layout
• Cut Tape packaging is suitable for assembly processes

The M5KP16AE3 remains the appropriate choice for applications requiring:

• MIL-PRF-19500 military qualification
• Extended low-temperature operation below -55°C
• Bulk packaging format
• Specific Microchip Technology sourcing requirements

Both components are in active production status and maintain identical functional characteristics for general-purpose transient voltage suppression.

Frequently Asked Questions (FAQ)

Q: Can the 5KP16A be used as a direct replacement for the M5KP16AE3 in existing designs?

A: Yes. The 5KP16A provides electrical equivalence across all critical parameters: 16V reverse standoff voltage, 26V clamping voltage, 5000W peak pulse power, and 1-channel unidirectional configuration. Both components are Zener-type TVS diodes in through-hole axial packages. The 5KP16A exceeds the minimum peak pulse current specification (196.2A versus 192A) and provides extended operating temperature range.

Q: Are there package compatibility considerations between DO-204AR and P600?

A: Both DO-204AR and P600 are axial through-hole package designations. Physical dimensions and lead spacing differ between manufacturers. PCB layout verification is necessary to confirm mechanical fit. Both packages are suitable for through-hole assembly processes.

Q: What is the significance of the RoHS compliance difference?

A: The M5KP16AE3 is RoHS non-compliant, while the 5KP16A is RoHS3 compliant. This distinction is relevant for applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance. Electrical performance is unaffected by RoHS status.

Q: Does the operating temperature range difference affect substitution suitability?

A: The M5KP16AE3 operates from -65°C to 150°C (TJ), while the 5KP16A operates from -55°C to 175°C (TJ). The 5KP16A is suitable for applications within its specified range. Applications requiring operation below -55°C require the M5KP16AE3. Applications requiring operation above 150°C require the 5KP16A.

Q: Why is military qualification (MIL-PRF-19500) not a substitution criterion?

A: Military qualification is a product certification attribute rather than an electrical or mechanical parameter. Applications requiring MIL-PRF-19500 qualification must specify the M5KP16AE3. Applications without military qualification requirements can select based on electrical equivalence and compliance status.

Q: What packaging formats are available for each part?

A: The M5KP16AE3 is supplied in Bulk packaging. The 5KP16A is supplied in Cut Tape (CT) packaging. Packaging format selection depends on assembly process requirements and order quantity considerations.

Q: Are there any applications where the M5KP16AE3 is preferred over the 5KP16A?

A: The M5KP16AE3 is preferred for applications requiring MIL-PRF-19500 military qualification, extended low-temperature operation below -55°C, or specific Microchip Technology sourcing mandates. For general-purpose transient voltage suppression without these specific requirements, the 5KP16A offers equivalent electrical performance with improved compliance status.
