5KP10C Equivalent & Substitute Parts

Part Overview

The 5KP10C is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage protection applications. This component features a 10V reverse standoff voltage, 5000W peak pulse power rating, and P600 axial through-hole packaging. The 5KP10C is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across voltage ratings, power dissipation, and mechanical form factor while meeting current product availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 5KP10C is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): Must be 10V to maintain circuit protection threshold
• Voltage - Clamping (Max) @ Ipp: Must not exceed 17.85V to ensure adequate transient suppression
• Power - Peak Pulse: Must be rated at 5000W (5kW) for equivalent energy dissipation capability
• Package / Case: Must be P600 axial through-hole to ensure mechanical and electrical compatibility
• Bidirectional Channels: Must be 1 channel for identical circuit function
• Operating Temperature Range: Must support -55°C ~ 175°C (TJ) for equivalent thermal performance
• RoHS Status: Must maintain ROHS3 compliance for regulatory alignment

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

Parameter Comparison

Engineering Selection Recommendations

5KP10CA (Littelfuse Inc., Active Status): This part is the direct active equivalent with identical voltage ratings and clamping characteristics. It maintains the same 10V reverse standoff voltage and achieves 17V clamping voltage with 300A peak pulse current. The part is actively manufactured and available in Cut Tape packaging, making it suitable for both prototype and production environments. ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) ensure regulatory and environmental compatibility.

SLD10-018-B (Littelfuse Inc., Active Status, AEC-Q101 Qualified): This substitute provides automotive-grade qualification under AEC-Q101 standard with identical electrical performance to 5KP10CA. It maintains 10V reverse standoff voltage, 17V clamping voltage, and 300A peak pulse current. The automotive qualification makes this part suitable for applications requiring automotive-grade component certification. Available in bulk packaging.

5KP10CE3/TR13 (Microchip Technology, Active Status): This substitute is manufactured by Microchip Technology and maintains the 10V reverse standoff voltage with a slightly higher clamping voltage of 18.8V at 266A peak pulse current. The marginally higher clamping voltage remains within acceptable transient suppression parameters. This part is actively produced and available in Tape & Reel packaging for high-volume production environments.

All three substitutes maintain full electrical and mechanical compatibility with the obsolete 5KP10C across the critical parameters of voltage rating, power dissipation, package form factor, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can 5KP10CA directly replace 5KP10C in existing designs? A: Yes. The 5KP10CA maintains identical voltage ratings (10V reverse standoff), equivalent clamping voltage (17V vs. 17.85V), and matching 5000W power dissipation. The P600 axial through-hole package is mechanically and electrically identical. The primary difference is product status: 5KP10CA is active and currently manufactured.

Q: What is the significance of the clamping voltage difference between 5KP10C (17.85V) and 5KP10CA (17V)? A: The 5KP10CA clamping voltage of 17V is lower than the 5KP10C specification of 17.85V, providing improved transient suppression performance. This represents a design improvement in the active equivalent and does not compromise circuit compatibility.

Q: Should I select SLD10-018-B for automotive applications? A: SLD10-018-B is qualified to AEC-Q101 automotive standard and is the appropriate choice for automotive applications requiring component-level qualification documentation. For non-automotive general-purpose applications, 5KP10CA is the standard equivalent.

Q: What is the difference between packaging options (Cut Tape, Bulk, Tape & Reel)? A: Cut Tape (CT) is suitable for small-quantity prototype and low-volume production. Bulk packaging is used for component kitting and assembly operations. Tape & Reel (TR) is optimized for high-volume automated assembly lines. All three packaging formats contain electrically identical components.

Q: Are all substitutes ROHS3 compliant? A: Yes. All three substitute parts (5KP10CA, SLD10-018-B, and 5KP10CE3/TR13) maintain ROHS3 compliance, ensuring regulatory alignment with environmental and hazardous substance restrictions.

Q: Can I use 5KP10CE3/TR13 from Microchip Technology as a cross-manufacturer substitute? A: Yes. The 5KP10CE3/TR13 maintains the critical electrical parameters (10V reverse standoff, 5000W power rating, P600 package) and is actively manufactured. The 18.8V clamping voltage is slightly higher than the original specification but remains within acceptable transient suppression performance for general-purpose applications.

Q: What inventory status should I consider when selecting a substitute? A: All three substitutes are listed as active products with current inventory availability. The 5KP10C is obsolete with limited remaining stock (1066 pcs). For new designs and ongoing production, selection should prioritize active substitutes with established supply chains.
