5KP10C-B Equivalent & Substitute Parts

Part Overview

The 5KP10C-B is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient protection applications. This component features a 10V reverse standoff voltage, 17.85V maximum clamping voltage, and 5000W peak pulse power rating in a P600 axial through-hole package. The 5KP10C-B is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP10C-B is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 10V
• Voltage - Clamping (Max) @ Ipp: 17V to 18.8V range
• Power - Peak Pulse: 5000W (5kW)
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature: -55°C ~ 175°C (TJ)
• Bidirectional Channels: 1
• Type: Zener

Substitute parts must maintain identical reverse standoff voltage, equivalent clamping voltage performance within acceptable tolerance, matching power dissipation capability, and compatible through-hole P600 axial packaging. All substitute parts listed are active products from Littelfuse Inc. or qualified cross-manufacturer alternatives, ensuring design continuity and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The 5KP10CA and 5KP10CA-B are direct Littelfuse Inc. substitutes with active product status, identical reverse standoff voltage, and equivalent clamping performance within 0.85V of the original specification. Both maintain full 5000W power dissipation and P600 axial through-hole compatibility. The 5KP10CA-B in bulk packaging provides cost-effective procurement for high-volume applications.

The SLD10-018-B represents a manufacturer-recommended alternative from Littelfuse Inc. with automotive-grade qualification (AEC-Q101) and active product status. This part is suitable for applications requiring automotive-level reliability and traceability, with clamping voltage and power ratings matching the original specification.

The 5KP10CE3/TR13 from Microchip Technology is a qualified cross-manufacturer substitute with active product status and ROHS3 compliance. This part exhibits slightly elevated clamping voltage (18.8V) and reduced peak pulse current (266A) compared to the original, but maintains equivalent 5000W power dissipation and full operating temperature range compatibility. This option is appropriate for applications where cross-manufacturer sourcing is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 5KP10CA directly replace the obsolete 5KP10C-B?

A: Yes. The 5KP10CA maintains identical reverse standoff voltage (10V), equivalent clamping voltage (17V versus 17.85V), matching 5000W power dissipation, and compatible P600 axial through-hole packaging. Both are Littelfuse Inc. products with ROHS3 compliance and -55°C to 175°C operating temperature range.

Q: What is the difference between 5KP10CA and 5KP10CA-B?

A: Both parts are electrically identical with matching electrical specifications. The primary difference is packaging: 5KP10CA is supplied in Cut Tape (CT) format, while 5KP10CA-B is supplied in Bulk format. Selection depends on procurement and assembly requirements.

Q: When should the SLD10-018-B be selected over the 5KP10CA?

A: The SLD10-018-B is appropriate for applications requiring automotive-grade qualification and AEC-Q101 certification. This part is manufacturer-recommended for automotive and mission-critical applications where enhanced traceability and qualification documentation are required.

Q: Is the 5KP10CE3/TR13 from Microchip Technology a suitable substitute?

A: Yes, the 5KP10CE3/TR13 is a qualified cross-manufacturer substitute with active product status. The part exhibits slightly higher clamping voltage (18.8V) and lower peak pulse current (266A) but maintains equivalent 5000W power dissipation. This option is suitable for applications where cross-manufacturer sourcing is acceptable and the clamping voltage tolerance is within design margins.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—5KP10CA, 5KP10CA-B, SLD10-018-B, and 5KP10CE3/TR13—are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

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

A: Yes. All substitute parts use identical P600 axial through-hole packaging and pin configuration, enabling direct PCB footprint compatibility without layout modifications.
