Substitute Part Grouping Explanation

The 5KP150CA qualifies as a direct substitute for the 5KP150C based on the following critical parameters:

• Voltage - Reverse Standoff (Typ): Both parts maintain 150V
• Bidirectional Channels: Both are single-channel devices
• Mounting Type: Both are through-hole mounted
• Package / Case: Both use P600 axial packaging
• Series: Both belong to the 5KP series
• Type: Both are Zener-type TVS diodes
• Power - Peak Pulse: Both are rated at 5000W (5kW)
• Operating Temperature Range: Both operate from -55°C to 175°C (TJ)
• RoHS Status: Both are ROHS3 Compliant
• Moisture Sensitivity Level: Both are MSL 1 (Unlimited)

The 5KP150CA is an Active product status variant with improved specifications, including a lower maximum clamping voltage (243V vs. 255.15V) and specified peak pulse current (21A), making it functionally compatible for the same application space.

Parameter Comparison

Engineering Selection Recommendations

The 5KP150CA is the recommended substitute for the obsolete 5KP150C. Both components are manufactured by Littelfuse Inc. and maintain identical electrical and mechanical specifications across all critical parameters: reverse standoff voltage, bidirectional channel configuration, power rating, operating temperature range, and package form factor.

The 5KP150CA carries Active product status, ensuring ongoing availability and manufacturing support. Both parts maintain ROHS3 compliance and MSL 1 rating, meeting current regulatory and environmental requirements.

The 5KP150CA exhibits a lower maximum clamping voltage (243V vs. 255.15V) and includes specified peak pulse current (21A), representing a refined variant within the same product series. These characteristics maintain functional compatibility for general-purpose transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can the 5KP150CA be used as a direct replacement for the 5KP150C?

A: Yes. Both components share identical reverse standoff voltage (150V), power rating (5000W), operating temperature range (-55°C to 175°C), and P600 axial through-hole package specifications. The 5KP150CA is the active production equivalent.

Q: What is the difference between the 5KP150C and 5KP150CA?

A: The primary differences are product status and clamping voltage specification. The 5KP150C is Obsolete with a maximum clamping voltage of 255.15V. The 5KP150CA is Active with a maximum clamping voltage of 243V and specified peak pulse current of 21A. Both maintain the same 150V reverse standoff voltage and 5000W power rating.

Q: Are there any package or mounting differences between these parts?

A: No. Both the 5KP150C and 5KP150CA use identical P600 axial through-hole packaging and mounting configuration.

Q: Do both parts meet current compliance standards?

A: Yes. Both the 5KP150C and 5KP150CA are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why should I select the 5KP150CA over the 5KP150C?

A: The 5KP150CA carries Active product status, ensuring reliable component availability and manufacturing continuity. The 5KP150C is Obsolete and subject to supply discontinuation.
