MP4KE160AE3 Equivalent & Substitute Parts

Part Overview

The MP4KE160AE3 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This through-hole component operates across a wide temperature range (-65°C to 150°C) and is qualified to MIL-PRF-19500 military standards. The device is currently in active production status with 916 units available in bulk packaging.

Identifying equivalent and substitute parts is necessary to address supply chain flexibility, packaging format requirements, compliance specifications, and operational temperature range needs for specific application environments.

Substitute Part Grouping Explanation

Substitution of the MP4KE160AE3 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 136V
• Voltage - Breakdown (Min): 152V
• Voltage - Clamping (Max) @ Ipp: 219V
• Current - Peak Pulse (10/1000µs): 1.8A minimum
• Power - Peak Pulse: 400W minimum
• Unidirectional Zener topology with single channel

Mechanical Equivalence Criteria:

• Package / Case: DO-204AL (DO-41) axial through-hole configuration
• Mounting Type: Through Hole

Compliance Considerations:

• RoHS status and REACH compliance affect application suitability
• Operating temperature range affects environmental qualification
• Product status must be Active

The P4KE160A substitute part meets all electrical and mechanical equivalence criteria while offering extended operating temperature range and improved compliance status.

Engineering Selection Recommendations

MP4KE160AE3 Selection Criteria:

• Applications requiring MIL-PRF-19500 military qualification
• Systems with temperature operating range limited to -65°C to 150°C
• Bulk packaging requirements for high-volume assembly
• RoHS non-compliant system environments

P4KE160A Selection Criteria:

• Applications requiring RoHS3 compliance
• Extended temperature operation up to 175°C
• Tape & Reel packaging for automated assembly processes
• Higher peak pulse current capability (1.9A vs 1.8A)
• Commercial and industrial applications without military qualification requirements

Both parts maintain identical voltage protection characteristics (136V standoff, 219V clamping) and mechanical compatibility in DO-204AL through-hole packages. Selection between these parts depends on compliance requirements, packaging format, and temperature range specifications rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can P4KE160A directly replace MP4KE160AE3 in existing designs?

A: Yes, from an electrical and mechanical standpoint. Both devices share identical voltage ratings (136V standoff, 219V clamping), peak pulse power (400W), and DO-204AL through-hole package configuration. However, compliance and temperature range differences must be evaluated for specific applications.

Q: What is the difference in peak pulse current between these parts?

A: The P4KE160A provides 1.9A peak pulse current compared to the MP4KE160AE3 at 1.8A. This represents a 5.6% increase in current handling capability, making the substitute part suitable for applications requiring higher transient current capacity.

Q: Why does the P4KE160A have an extended operating temperature range?

A: The P4KE160A operates from -55°C to 175°C, compared to the MP4KE160AE3 range of -65°C to 150°C. This extended upper temperature limit (175°C vs 150°C) accommodates high-temperature industrial and automotive applications. The higher lower limit (-55°C vs -65°C) reflects different design specifications between manufacturers.

Q: What packaging format differences exist between these parts?

A: The MP4KE160AE3 is supplied in Bulk packaging, while the P4KE160A uses Tape & Reel (TR) format. Bulk packaging suits manual assembly and small-quantity applications, whereas Tape & Reel format is optimized for automated pick-and-place assembly processes.

Q: Are there compliance differences between these substitute parts?

A: Yes. The MP4KE160AE3 is RoHS non-compliant and qualified to MIL-PRF-19500 military standards. The P4KE160A is RoHS3 compliant, making it suitable for commercial and industrial applications with environmental compliance requirements. Both parts are REACH Unaffected.

Q: Can I use P4KE160A in a military-qualified design requiring MIL-PRF-19500?

A: No. The P4KE160A does not carry MIL-PRF-19500 qualification. If military qualification is a design requirement, the MP4KE160AE3 must be used. For non-military applications, the P4KE160A is electrically and mechanically equivalent.

Q: What is the base product number for both parts?

A: Both the MP4KE160AE3 and P4KE160A share the base product number P4KE160, indicating they are part of the same voltage protection series with identical core electrical specifications.
