Equivalent & Substitute Parts for 5KP220C

Part Overview

The 5KP220C is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage clamping applications. This component features a 220V reverse standoff voltage with a maximum clamping voltage of 389.66V at peak pulse current, rated for 5000W peak pulse power dissipation. The 5KP220C is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP220C is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Reverse standoff voltage within the 220V specification
• Bidirectional channel configuration (1 channel)
• Through-hole axial mounting compatibility
• Operating temperature range of -55°C to 175°C
• Zener diode type classification
• General-purpose application suitability

Secondary Compatibility Factors:

• Peak pulse power rating (5000W preferred, lower ratings acceptable with application verification)
• Clamping voltage performance at rated peak pulse current
• RoHS3 compliance and environmental standards

The substitute parts listed below maintain electrical compatibility within the defined voltage and thermal operating windows while accommodating variations in package form factor and peak pulse current ratings.

Parameter Comparison

Engineering Selection Recommendations

5KP220CA (Direct Equivalent)

The 5KP220CA is the primary substitute for the obsolete 5KP220C. Both components are manufactured by Littelfuse Inc. within the same 5KP series, maintaining identical reverse standoff voltage (220V), operating temperature range (-55°C to 175°C), and peak pulse power rating (5000W). The 5KP220CA is currently in active production status with ROHS3 compliance. The primary difference is packaging format (Cut Tape versus standard packaging) and improved clamping voltage performance (371.1V versus 389.66V). This component is the recommended first choice for direct replacement applications.

1.5KE250CA (Alternative with Reduced Power Rating)

The 1.5KE250CA, manufactured by Taiwan Semiconductor Corporation, provides electrical compatibility with a reverse standoff voltage of 214V and clamping voltage of 344V. This component carries AEC-Q101 automotive qualification and ROHS3 compliance. The peak pulse power rating is reduced to 1500W, requiring application-level verification that transient energy levels remain within this constraint. The DO-201AA package form factor differs from the P600 axial package, necessitating PCB layout modification. This substitute is suitable for applications with lower transient energy requirements.

P6KE250CA-TP (Alternative with Lowest Power Rating)

The P6KE250CA-TP, manufactured by Micro Commercial Co, offers the lowest peak pulse power rating at 600W with a reverse standoff voltage of 214V and clamping voltage of 344V. This component is qualified for telecom applications and maintains ROHS3 compliance. The DO-204AC (DO-15) package form factor requires PCB redesign. This substitute is applicable only to circuits with minimal transient energy exposure and is not recommended as a primary replacement due to significantly reduced power dissipation capability.

Frequently Asked Questions (FAQ)

Q: Can the 5KP220CA directly replace the 5KP220C without PCB modification?

A: Yes. The 5KP220CA maintains the same P600 axial package form factor, reverse standoff voltage (220V), operating temperature range, and peak pulse power rating (5000W) as the 5KP220C. No PCB layout changes are required for direct substitution.

Q: What are the key differences between the 5KP220CA and the 1.5KE250CA?

A: The primary differences are: (1) Peak pulse power rating—5KP220CA is rated for 5000W versus 1.5KE250CA at 1500W; (2) Package form factor—5KP220CA uses P600 axial versus 1.5KE250CA uses DO-201AA; (3) Reverse standoff voltage—5KP220CA is 220V versus 1.5KE250CA is 214V. The 1.5KE250CA requires application verification that transient energy levels do not exceed 1500W and PCB redesign for the different package.

Q: Is the P6KE250CA-TP suitable for general-purpose applications?

A: The P6KE250CA-TP is qualified for telecom applications with a 600W peak pulse power rating. For general-purpose applications originally designed around the 5KP220C (5000W rating), this component is not recommended due to insufficient power dissipation capability. Application-specific transient energy analysis is required before selection.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. The 5KP220CA, 1.5KE250CA, and P6KE250CA-TP are all ROHS3 compliant, matching the environmental standards of the original 5KP220C.

Q: What is the impact of different package form factors on circuit design?

A: The 5KP220CA maintains the P600 axial package of the original 5KP220C, requiring no PCB modification. The 1.5KE250CA uses DO-201AA package and the P6KE250CA-TP uses DO-204AC (DO-15) package, both requiring PCB layout redesign, including through-hole spacing and trace routing adjustments. Mechanical clearance verification is necessary before implementation.

Q: Are there automotive-grade alternatives available?

A: The 1.5KE250CA carries AEC-Q101 automotive qualification. The P6KE250CA-TP does not list automotive qualification in the provided specifications. If automotive-grade certification is a design requirement, the 1.5KE250CA is the qualified option among the listed substitutes.
