5KP150CA-TP Equivalent & Substitute Parts

Part Overview

The 5KP150CA-TP is a transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This through-hole axial component operates with a 150V reverse standoff voltage and provides 5000W peak pulse power dissipation. The part is currently active in production and ROHS3 compliant, making it suitable for modern electronic circuit protection requirements. Substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP150CA-TP are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 150V
• Voltage - Breakdown (Min): 167V or higher
• Voltage - Clamping (Max) @ Ipp: 243V or lower
• Power - Peak Pulse: 5000W or higher
• Mounting Type: Through Hole
• Package / Case: Axial configuration
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Type: Zener diode, bidirectional, single channel
• RoHS Status: ROHS3 Compliant

Parts meeting these criteria maintain functional equivalence for general-purpose transient voltage suppression applications. Packaging format (Cut Tape vs. Bulk) does not affect electrical substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance, ensuring regulatory alignment with current manufacturing standards. The 5KP150CA and 5KP150CA-B from Littelfuse Inc. provide direct electrical equivalence with identical voltage and power specifications to the main part. The 15KPA150CA from MDE Semiconductor Inc. offers enhanced power dissipation capability (15kW vs. 5kW) while maintaining the same reverse standoff and clamping voltage parameters, providing a higher-performance alternative for applications requiring additional thermal margin.

Package case differences (R-6 vs. P600) represent physical form factor variations within the axial through-hole category and do not affect electrical substitution eligibility. Selection between Cut Tape and Bulk packaging depends on procurement and assembly requirements rather than technical performance.

Frequently Asked Questions (FAQ)

Q: Can the 15KPA150CA replace the 5KP150CA-TP in all applications?

A: The 15KPA150CA meets all electrical substitution criteria with matching reverse standoff voltage (150V), breakdown voltage (167.6V minimum), and clamping voltage (241.9V maximum). The higher power rating (15kW vs. 5kW) provides additional thermal capability. Physical package differences (P600 vs. R-6) require board layout verification for mechanical fit.

Q: What is the difference between 5KP150CA and 5KP150CA-B?

A: These parts are electrically identical with matching voltage and power specifications. The designation difference reflects packaging format: 5KP150CA is supplied in Cut Tape (CT), while 5KP150CA-B is supplied in Bulk. Both are manufactured by Littelfuse Inc. and are ROHS3 compliant.

Q: Are package case differences (R-6 vs. P600) significant for substitution?

A: Both R-6 and P600 are axial through-hole packages suitable for PCB mounting. Physical dimensions differ, requiring verification of board layout and hole spacing compatibility. Electrical performance is independent of package case designation.

Q: Do all substitute parts have the same operating temperature range?

A: Yes, all listed substitute parts operate across the -55°C to 175°C (TJ) temperature range, matching the main part specification.

Q: What compliance certifications apply to these parts?

A: All parts are ROHS3 compliant. The main part and Littelfuse substitutes have REACH Unaffected status. The 15KPA150CA has REACH information available upon request. All parts carry EAR99 ECCN classification.
