5KP180C Equivalent & Substitute Parts

Part Overview

The 5KP180C is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage clamping applications. This component features a 180V reverse standoff voltage rating and 306.6V maximum clamping voltage with 5000W peak pulse power handling capability in a through-hole P600 axial package.

The 5KP180C is classified as obsolete. Identifying suitable substitute components ensures design continuity and maintains supply chain reliability for applications requiring equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP180C is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 180V
• Voltage - Clamping (Max) @ Ipp: Must be within acceptable operating range
• Power - Peak Pulse: 5000W (5kW)
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• RoHS Compliance: ROHS3 Compliant

The 5KP180CA meets all substitution criteria. Both components share identical reverse standoff voltage, peak pulse power rating, mounting configuration, package type, operating temperature range, and RoHS compliance status. The primary difference is product status: 5KP180CA is active and available in higher inventory quantities.

Parameter Comparison

Engineering Selection Recommendations

The 5KP180CA is the direct substitute for the 5KP180C. Both components are ROHS3 compliant and manufactured by Littelfuse Inc. The 5KP180CA is currently active in production with significantly higher inventory availability (2800 pcs vs. 912 pcs), ensuring reliable supply chain access.

The 5KP180CA exhibits a lower maximum clamping voltage (292V vs. 306.6V) and higher minimum breakdown voltage (200V vs. 189.45V), representing tighter voltage specifications. These characteristics are compatible with the 180V reverse standoff voltage rating and maintain the 5000W peak pulse power handling capability across the identical P600 axial through-hole package.

Selection of the 5KP180CA eliminates obsolescence risk while maintaining electrical and mechanical compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the 5KP180CA directly replace the 5KP180C in existing designs?

A: Yes. Both components share identical reverse standoff voltage (180V), peak pulse power rating (5000W), mounting type (through hole), package configuration (P600 axial), and operating temperature range (-55°C ~ 175°C). The 5KP180CA is the designated substitute for the obsolete 5KP180C.

Q: What is the difference in clamping voltage between these parts?

A: The 5KP180C specifies a maximum clamping voltage of 306.6V, while the 5KP180CA specifies 292V. The 5KP180CA also has a higher minimum breakdown voltage (200V vs. 189.45V). These represent tighter voltage specifications within the same functional class.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5KP180C and 5KP180CA are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: Why is the 5KP180C classified as obsolete?

A: The 5KP180C has been discontinued by Littelfuse Inc. The 5KP180CA is the active production equivalent, offering improved supply chain availability and ongoing manufacturer support.

Q: Does packaging differ between these components?

A: No. Both components use identical P600 axial through-hole packaging, ensuring mechanical compatibility in PCB designs without layout modifications.
