5KP58C-B Equivalent & Substitute Parts

Part Overview

The 5KP58C-B is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient 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 part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP58C-B is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 58V
• Bidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Power - Peak Pulse: 5000W (5kW)
• Operating Temperature Range: -55°C ~ 175°C (TJ)

Substitute parts must maintain identical or functionally equivalent values for these parameters. Variations in voltage clamping characteristics, peak pulse current, and breakdown voltage are acceptable within the constraints of the application, provided the reverse standoff voltage and power rating remain consistent.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Littelfuse 5KP Series)

The 5KP58CA and 5KP58CA-B are direct functional equivalents from Littelfuse. Both maintain the 58V reverse standoff voltage, 5000W power rating, and P600 axial package. These parts are in active production status. The 5KP58CA is supplied in cut tape packaging, while the 5KP58CA-B is supplied in bulk. Both are ROHS3 compliant and suitable for direct replacement in existing designs.

Secondary Substitute (Microchip Technology 5KP58CE3/TR13)

The 5KP58CE3/TR13 is a manufacturer-recommended substitute from Microchip Technology. It maintains the 58V reverse standoff voltage, 5000W power rating, and P600 axial package. This part is in active production status and ROHS3 compliant. The voltage clamping characteristic is 103V, which is higher than the main part's 98.28V. This part is supplied in tape and reel packaging.

Alternative Substitute (Micro Commercial Co AK15-058C-BP)

The AK15-058C-BP is a manufacturer-recommended substitute from Micro Commercial Co. It maintains the 58V reverse standoff voltage and through-hole mounting. However, this part features a right-angle bend package configuration (24.15mm center) rather than standard axial orientation, and the operating temperature range is limited to -55°C ~ 150°C (TJ), which is 25°C lower than the main part. Peak pulse current specification differs significantly at 15kA (8/20µs). This part is in active production status.

Frequently Asked Questions (FAQ)

Q: Can 5KP58CA be used as a direct replacement for 5KP58C-B?

A: Yes. Both parts share identical reverse standoff voltage (58V), power rating (5000W), operating temperature range (-55°C ~ 175°C), and P600 axial package. The 5KP58CA is in active production status, making it the preferred substitute for the obsolete 5KP58C-B.

Q: What is the difference between 5KP58CA and 5KP58CA-B?

A: Both parts are electrically identical. The difference is packaging: 5KP58CA is supplied in cut tape, while 5KP58CA-B is supplied in bulk. Selection depends on procurement and handling requirements.

Q: Is the Microchip 5KP58CE3/TR13 compatible with the 5KP58C-B?

A: Yes. The 5KP58CE3/TR13 maintains the 58V reverse standoff voltage, 5000W power rating, and P600 axial package. The voltage clamping is 103V compared to 98.28V in the main part. This difference is within acceptable substitution parameters for general-purpose transient protection applications.

Q: Can the AK15-058C-BP replace the 5KP58C-B?

A: The AK15-058C-BP maintains the 58V reverse standoff voltage and through-hole mounting. However, the package configuration is right-angle bend (24.15mm center) rather than standard axial, and the operating temperature maximum is 150°C instead of 175°C. Physical package differences may require PCB layout modifications. Verify mechanical fit and thermal requirements before substitution.

Q: What parameters must remain constant when selecting a substitute?

A: The reverse standoff voltage (58V), bidirectional channel configuration (1), mounting type (through hole), and power rating (5000W) must remain constant. Variations in voltage clamping, breakdown voltage, and peak pulse current are acceptable within application requirements.

Q: Are all substitute parts ROHS3 compliant?

A: The Littelfuse 5KP58CA, 5KP58CA-B, and Microchip 5KP58CE3/TR13 are ROHS3 compliant. The Micro Commercial Co AK15-058C-BP does not specify RoHS status in the provided data.
