5KP58C Equivalent & Substitute Parts

Part Overview

The 5KP58C is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 58V reverse standoff voltage rating and 5000W peak pulse power handling capability in a through-hole P600 axial package. The 5KP58C is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain compatibility across voltage ratings, power dissipation, package type, and operating temperature ranges to ensure functional equivalence in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP58C are qualified based on the following critical parameters:

• Voltage - Reverse Standoff (Typ): Must equal 58V to maintain circuit protection threshold
• Bidirectional Channels: Must equal 1 for equivalent protection topology
• Type: Must be Zener diode technology
• Mounting Type: Must be Through Hole for PCB compatibility
• Package / Case: Must be P600 Axial or compatible axial package
• Power - Peak Pulse: Must equal or exceed 5000W for equivalent energy dissipation
• Operating Temperature Range: Must support -55°C to 175°C minimum
• RoHS Compliance: Must maintain ROHS3 Compliant status

Three substitute parts meet these criteria with variations in clamping voltage, peak pulse current, and product status.

Parameter Comparison

Engineering Selection Recommendations

5KP58CA (Littelfuse) is the primary direct substitute for the 5KP58C. Both components are manufactured by Littelfuse, share identical voltage ratings and power specifications, and maintain ROHS3 compliance. The 5KP58CA is currently in active production status with higher inventory availability (5582 pcs) compared to the obsolete 5KP58C. The clamping voltage is slightly lower (93.6V vs 98.28V), providing marginally tighter voltage regulation. This part is suitable for direct replacement in existing designs.

5KP58CE3/TR13 (Microchip Technology) is a manufacturer-recommended alternative offering active product status and ROHS3 compliance. The clamping voltage is higher (103V), which may be acceptable depending on circuit tolerance requirements. This part maintains identical reverse standoff voltage, breakdown voltage, and operating temperature range. Microchip's active status ensures long-term availability and supply chain stability.

AK15-058C-BP (Micro Commercial Co) is a manufacturer-recommended option with significantly higher peak pulse current capability (15000A at 8/20µs pulse width). This part features a right-angle bend package configuration (24.15mm center) rather than standard axial orientation, requiring PCB layout verification. The maximum operating temperature is reduced to 150°C, which may limit applicability in high-temperature environments. This substitute is suitable only when higher current handling and package geometry are compatible with circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5KP58CA directly replace the 5KP58C without circuit modifications?

A: Yes. The 5KP58CA maintains identical reverse standoff voltage (58V), power rating (5000W), package type (P600 Axial), and operating temperature range (-55 to 175°C). The lower clamping voltage (93.6V vs 98.28V) represents improved voltage regulation and is functionally compatible with the original design.

Q: What is the primary difference between 5KP58CA and 5KP58CE3/TR13?

A: Both parts share identical voltage ratings and power specifications. The primary difference is clamping voltage: 5KP58CA clamps at 93.6V while 5KP58CE3/TR13 clamps at 103V. The 5KP58CE3/TR13 is supplied in Tape & Reel packaging, while 5KP58CA is supplied in Cut Tape. Manufacturer origin differs (Littelfuse vs Microchip Technology).

Q: Is the AK15-058C-BP suitable as a drop-in replacement?

A: The AK15-058C-BP is not a drop-in replacement due to package geometry differences. It features a right-angle bend configuration (24.15mm center) rather than standard axial orientation, requiring PCB layout verification. Additionally, the maximum operating temperature is 150°C, which is 25°C lower than the original specification. This part is suitable only when higher peak pulse current (15000A) is required and package geometry is compatible.

Q: Are all substitute parts RoHS3 compliant?

A: The 5KP58CA and 5KP58CE3/TR13 are explicitly ROHS3 compliant. The AK15-058C-BP does not specify RoHS status in the provided data. Verify RoHS compliance requirements with the manufacturer before selection.

Q: What packaging options are available for these substitutes?

A: The 5KP58CA is supplied in Cut Tape (CT) packaging. The 5KP58CE3/TR13 is supplied in Tape & Reel (TR) packaging for automated assembly. The AK15-058C-BP is supplied in Bulk packaging. Select packaging based on production volume and assembly process requirements.
