5KP7.0 Equivalent & Substitute Parts

Part Overview

The 5KP7.0 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. It features a 7V reverse standoff voltage, 12.6V maximum clamping voltage, and 5000W peak pulse power rating in a through-hole P600 axial package. The product is currently classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 5KP7.0 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Unidirectional TVS diode topology (1 channel)
• Reverse standoff voltage: 7V nominal
• Voltage clamping range: 12V to 12.6V maximum
• Through-hole axial package configuration
• Operating temperature range: -55°C to 175°C
• RoHS3 compliance

Substitute Categories:

1. Direct Manufacturer Equivalent (5KP7.0A): Same manufacturer (Littelfuse Inc.), identical series (5KP), matching electrical specifications, and identical package. Product status is active, ensuring ongoing availability.

2. Cross-Manufacturer Substitute (1.5KE8.2A-TP): Different manufacturer (Micro Commercial Co) with comparable voltage parameters (7.02V standoff, 12.1V clamping) and through-hole axial package. Power rating differs at 1500W versus 5000W, representing a lower-power alternative suitable for applications with reduced transient energy requirements.

Parameter Comparison

Engineering Selection Recommendations

5KP7.0A (Littelfuse Inc.): This is the primary substitute for the obsolete 5KP7.0. It maintains identical electrical specifications, package configuration, and power rating while offering active product status and improved availability. The 5KP7.0A is manufactured by the same supplier and carries ROHS3 compliance with REACH affected status. This part is recommended for direct replacement in applications requiring the full 5000W peak pulse power rating.

1.5KE8.2A-TP (Micro Commercial Co): This cross-manufacturer substitute provides comparable voltage protection characteristics with a 7.02V standoff and 12.1V clamping voltage. However, the power rating is reduced to 1500W, making it suitable only for applications with lower transient energy levels. The DO-201AE package is mechanically compatible with through-hole mounting but differs from the P600 package. This part is ROHS3 compliant with REACH unaffected status. Selection of this substitute requires confirmation that the application's transient energy does not exceed 1500W.

Frequently Asked Questions (FAQ)

Q: Can 5KP7.0A be used as a direct replacement for 5KP7.0?

A: Yes. The 5KP7.0A is a direct equivalent with identical electrical specifications, package type, and power rating. The primary advantage is active product status, ensuring continued availability and supply chain reliability.

Q: What is the key difference between 5KP7.0A and 1.5KE8.2A-TP?

A: The primary difference is power dissipation capacity. The 5KP7.0A maintains the 5000W peak pulse rating, while the 1.5KE8.2A-TP is rated for 1500W. Voltage parameters are comparable. Selection depends on the transient energy levels in the application.

Q: Are the packages interchangeable between 5KP7.0A and 1.5KE8.2A-TP?

A: Both use through-hole axial configurations, but the specific packages differ (P600 versus DO-201AE). Physical dimensions and PCB footprints may vary. Mechanical compatibility must be verified for the target application.

Q: Does the 1.5KE8.2A-TP meet the same compliance standards?

A: Yes. The 1.5KE8.2A-TP is ROHS3 compliant. However, it has REACH unaffected status, whereas the 5KP7.0A has REACH affected status. Compliance requirements for your application should be verified.

Q: Why is the 5KP7.0 marked as obsolete?

A: Product obsolescence is determined by the manufacturer. The 5KP7.0A serves as the active replacement, maintaining the same specifications and performance characteristics.
