5KP200C-B Transient Voltage Suppressor (TVS) Equivalent & Substitute Parts

Part Overview

The 5KP200C-B is a through-hole Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse, designed for general-purpose transient voltage protection applications. This component features a 200V reverse standoff voltage rating and 345.66V maximum clamping voltage with 5kW peak pulse power handling capability. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for continued system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP200C-B is determined by the following critical parameters that must remain constant or within acceptable tolerance:

• Voltage - Reverse Standoff (Typ): 200V (primary protection threshold)
• Mounting Type: Through Hole (mechanical compatibility)
• Package / Case: P600 or R-6 Axial (footprint compatibility)
• Operating Temperature Range: -55°C ~ 175°C (TJ) (thermal compatibility)
• Type: Zener (functional classification)
• Bidirectional Channels: 1 (circuit topology requirement)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

Substitute parts are grouped into two categories based on power rating and peak pulse current capability:

Category A (5kW Rating): Direct electrical and mechanical equivalents with identical power dissipation specifications. These parts maintain the same thermal and electrical performance envelope as the original component.

Category B (15kW Rating): Enhanced performance alternatives with higher power handling capability. These parts provide superior transient suppression capacity while maintaining the same voltage protection threshold and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (5kW Category):

5KP200CA and 5KP200CA-B are direct functional equivalents manufactured by Littelfuse with active product status. Both maintain identical voltage protection thresholds (200V reverse standoff), operating temperature range, and power dissipation specifications. The distinction between these parts is packaging format: 5KP200CA is supplied in Cut Tape (CT) format with 2200 units in stock, while 5KP200CA-B is supplied in Bulk format with 1051 units in stock. Selection between these two depends on procurement and assembly requirements. Both parts are ROHS3 compliant with unlimited moisture sensitivity rating.

Enhanced Performance Substitutes (15kW Category):

15KP200CA-TP (Micro Commercial Co) and 15KPA200CAE3/TR13 (Microchip Technology) provide higher power handling capacity at 15kW peak pulse rating. These parts maintain the 200V reverse standoff voltage and identical operating temperature range, ensuring circuit-level compatibility. The 15KPA200CAE3/TR13 offers superior peak pulse current capability (47.3A) compared to the 15KP200CA-TP. Both parts are ROHS3 compliant and carry active product status. Selection of 15kW-rated alternatives is appropriate for applications requiring enhanced transient suppression margin or where circuit redesign permits higher power dissipation capability.

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring regulatory and environmental compatibility with the original component.

Frequently Asked Questions (FAQ)

Q: Can 5KP200CA directly replace 5KP200C-B in existing designs?

A: Yes. The 5KP200CA maintains identical voltage protection parameters (200V reverse standoff, 329.2V clamping voltage), operating temperature range (-55°C to 175°C), and through-hole P600 axial package. The primary difference is lower clamping voltage (329.2V vs. 345.66V), which provides improved protection margin. Both are ROHS3 compliant with unlimited moisture sensitivity.

Q: What is the difference between 5KP200CA and 5KP200CA-B?

A: These parts are electrically identical. The difference is packaging format: 5KP200CA is supplied in Cut Tape (CT) format, while 5KP200CA-B is supplied in Bulk format. Selection depends on procurement method and assembly line requirements. Both maintain identical electrical specifications and compliance ratings.

Q: When should I use 15kW-rated alternatives instead of 5kW equivalents?

A: The 15kW-rated parts (15KP200CA-TP and 15KPA200CAE3/TR13) are appropriate when circuit analysis indicates higher transient energy absorption capacity is beneficial. These parts maintain the same 200V protection threshold and operating temperature range. Selection should be based on circuit requirements and available board space, as the R-6 package (15KP200CA-TP) differs from the P600 package used in the original design.

Q: Are there package compatibility considerations between substitute parts?

A: Yes. The 5KP200CA, 5KP200CA-B, and 15KPA200CAE3/TR13 use the P600 axial package, which is directly compatible with the original 5KP200C-B footprint. The 15KP200CA-TP uses the R-6 axial package, which has different physical dimensions and requires board layout verification before implementation.

Q: Do all substitute parts meet the same regulatory requirements as the original component?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original 5KP200C-B specifications. The 5KP200CA, 5KP200CA-B, 15KP200CA-TP, and 15KPA200CAE3/TR13 all carry REACH Unaffected status where specified.
