5KP64C Equivalent & Substitute Parts

Part Overview

The 5KP64C is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage protection applications. This component features a 64V reverse standoff voltage rating and 5000W peak pulse power handling capability in a through-hole P600 axial package. The 5KP64C is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP64C is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 64V
• Voltage - Breakdown (Min): minimum 67.37V
• Voltage - Clamping (Max) @ Ipp: maximum 108.15V
• Power - Peak Pulse: 5000W (5kW)
• Type: Zener, Bidirectional

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Series: 5KP

The 5KP64CA qualifies as a direct substitute because it maintains identical voltage ratings, power handling, package configuration, and thermal operating range while remaining within the specified clamping voltage envelope.

Parameter Comparison

Engineering Selection Recommendations

The 5KP64CA is the recommended substitute for the obsolete 5KP64C. Both components are manufactured by Littelfuse Inc. within the same 5KP series and maintain identical electrical performance specifications for voltage suppression applications. The 5KP64CA offers the advantage of active product status, ensuring long-term availability and supply chain continuity. Both parts are ROHS3 compliant and operate across the same temperature range (-55°C to 175°C). The 5KP64CA features a lower clamping voltage (103V versus 108.15V), which provides improved transient suppression performance while remaining within acceptable design margins for 64V standoff applications. Packaging and mounting characteristics are identical, enabling direct board-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 5KP64CA be used as a direct replacement for the 5KP64C?

A: Yes. The 5KP64CA is a direct substitute. Both components share identical reverse standoff voltage (64V), peak pulse power rating (5000W), operating temperature range (-55°C to 175°C), and P600 axial through-hole package configuration. The 5KP64CA features improved clamping voltage performance (103V versus 108.15V) and is currently in active production status.

Q: What is the primary reason to substitute the 5KP64C?

A: The 5KP64C is classified as obsolete. The 5KP64CA provides equivalent electrical performance with the advantage of active product status, ensuring reliable procurement and supply chain availability.

Q: Are there any electrical performance differences between these parts?

A: The 5KP64CA exhibits a lower maximum clamping voltage (103V) compared to the 5KP64C (108.15V). This represents improved transient suppression capability and is compatible with 64V standoff voltage applications. The 5KP64CA also specifies peak pulse current at 49.5A, providing additional performance documentation.

Q: Can these parts be used interchangeably on existing PCBs?

A: Yes. Both components use identical P600 axial through-hole packaging and mounting configuration, enabling direct board-level substitution without PCB redesign or component repositioning.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5KP64C and 5KP64CA are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.
