3KP200C Equivalent & Substitute Parts

Part Overview

The 3KP200C is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage protection applications. This component features a 200V reverse standoff voltage rating and a 345.66V maximum clamping voltage with 9.1A peak pulse current capability in a through-hole P600 axial package.

The 3KP200C is classified as obsolete. Identifying suitable substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3KP200C is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): Must match at 200V to maintain circuit protection thresholds
• Package / Case: Must be P600 axial through-hole to ensure mechanical and electrical compatibility with existing PCB layouts
• Mounting Type: Must be through-hole to maintain assembly compatibility
• Bidirectional Channels: Must be 1 channel to match the original design
• Type: Must be Zener TVS diode to maintain functional equivalence

The 5KP200CA meets all substitution criteria. While it exhibits higher peak pulse current (15.5A vs. 9.1A) and greater peak pulse power (5000W vs. 3000W), these represent enhanced performance characteristics within the same voltage class and package specification. The lower clamping voltage (329.2V vs. 345.66V) provides improved transient suppression performance.

Parameter Comparison

Engineering Selection Recommendations

The 5KP200CA is the direct substitute for the obsolete 3KP200C. Both components are manufactured by Littelfuse Inc. and maintain identical compliance certifications (ROHS3 Compliant, MSL 1). The 5KP200CA carries active product status, ensuring long-term availability and supply chain continuity.

The 5KP200CA provides equivalent or superior electrical performance across all critical parameters. The identical reverse standoff voltage (200V) and operating temperature range (-55°C ~ 175°C) ensure functional compatibility. The enhanced peak pulse current and power ratings of the 5KP200CA represent performance improvements that do not compromise circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5KP200CA be used as a direct replacement for the 3KP200C?

A: Yes. Both components share identical reverse standoff voltage (200V), package type (P600 axial), mounting configuration (through-hole), and operating temperature range. The 5KP200CA is electrically and mechanically compatible with the 3KP200C.

Q: What are the key differences between these parts?

A: The 5KP200CA provides higher peak pulse current (15.5A vs. 9.1A) and greater peak pulse power (5000W vs. 3000W). The 5KP200CA also exhibits a lower maximum clamping voltage (329.2V vs. 345.66V), which improves transient suppression performance. The 5KP200CA maintains active product status, whereas the 3KP200C is obsolete.

Q: Are there any package or mounting differences?

A: No. Both the 3KP200C and 5KP200CA use the P600 axial through-hole package. They are mechanically interchangeable on existing PCB layouts without modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level. They meet identical regulatory and environmental requirements.

Q: Why is the 3KP200C obsolete?

A: The 3KP200C has been discontinued by Littelfuse Inc. The 5KP200CA represents the current active product offering in this voltage and package class.
