5KP100C Equivalent & Substitute Parts

Part Overview

The 5KP100C is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a P600 axial package with a 100V reverse standoff voltage rating and 5000W peak pulse power handling capability. The 5KP100C is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Active alternatives from both Littelfuse and Microchip Technology provide functionally compatible solutions with comparable electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP100C is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): Must be 100V to maintain circuit protection thresholds
• Power - Peak Pulse: Must be 5000W (5kW) to handle transient energy
• Package / Case: Must be P600 axial for mechanical and electrical compatibility
• Mounting Type: Must be Through Hole for PCB integration
• Operating Temperature Range: Must support -55°C ~ 175°C (TJ)
• Type: Must be Zener bidirectional TVS diode
• Bidirectional Channels: Must be 1 channel

Substitute parts are grouped into two categories based on clamping voltage performance:

Group A (Lower Clamping Voltage): 5KP100CA - Littelfuse active product with 162V maximum clamping voltage and 31.5A peak pulse current

Group B (Higher Clamping Voltage): 5KP100CAE3/TR13 and 5KP100CE3/TR13 - Microchip Technology active products with clamping voltages of 162V and 179V respectively

All substitute parts maintain the 100V reverse standoff voltage, 5000W peak pulse power rating, P600 axial package, and through-hole mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

5KP100CA is the direct Littelfuse equivalent, maintaining manufacturer continuity with active product status. This part is available in Cut Tape packaging and provides 31.5A peak pulse current with 162V clamping voltage. Selection of this part is appropriate for applications requiring Littelfuse component sourcing or existing supply chain relationships.

5KP100CAE3/TR13 is a Microchip Technology alternative with manufacturer-recommended status. This part delivers 30.9A peak pulse current and 162V clamping voltage in Tape & Reel packaging. The electrical performance is equivalent to 5KP100CA with slightly lower peak pulse current specification.

5KP100CE3/TR13 is a Microchip Technology alternative with higher clamping voltage performance at 179V and 27.9A peak pulse current. This part is suitable for applications where higher clamping voltage tolerance is acceptable or beneficial for circuit protection margin.

All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring regulatory and environmental compatibility with the original 5KP100C specification.

Frequently Asked Questions (FAQ)

Q: Can 5KP100CA be used as a direct replacement for 5KP100C?

A: Yes. The 5KP100CA maintains identical reverse standoff voltage (100V), peak pulse power (5000W), package type (P600 axial), and operating temperature range (-55°C ~ 175°C). The primary difference is active product status and specified peak pulse current of 31.5A.

Q: What is the difference between the Littelfuse and Microchip alternatives?

A: 5KP100CA is manufactured by Littelfuse Inc. and available in Cut Tape packaging. 5KP100CAE3/TR13 and 5KP100CE3/TR13 are manufactured by Microchip Technology and supplied in Tape & Reel format. Electrical specifications are comparable, with clamping voltage differences noted in the parameter comparison table.

Q: Does clamping voltage variation affect substitutability?

A: Clamping voltage differences (162V vs. 179V) remain within acceptable tolerance for general-purpose transient voltage suppression applications. Both values provide adequate protection for 100V standoff circuits. Circuit-specific requirements should determine selection between lower and higher clamping voltage options.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (5KP100CA, 5KP100CAE3/TR13, 5KP100CE3/TR13) maintain ROHS3 compliance status, matching the original 5KP100C specification.

Q: What packaging formats are available for these substitutes?

A: 5KP100CA is available in Cut Tape (CT) format. 5KP100CAE3/TR13 and 5KP100CE3/TR13 are supplied in Tape & Reel (TR) format. Packaging selection depends on production volume and assembly equipment compatibility.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the circuit design accommodates the specified clamping voltage and peak pulse current parameters. All substitute parts share identical reverse standoff voltage, power rating, package type, and operating temperature range with the 5KP100C.
