5KP180CA-B Equivalent & Substitute Parts

Part Overview

The 5KP180CA-B is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient protection applications. This through-hole component features a 180V reverse standoff voltage with 292V maximum clamping voltage and 17.5A peak pulse current capability. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to address packaging format availability and inventory requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP180CA-B is determined by the following critical parameters that must remain constant across all equivalent parts:

• Voltage - Reverse Standoff: 180V
• Voltage - Breakdown (Min): 200V
• Voltage - Clamping (Max) @ Ipp: 292V
• Current - Peak Pulse (10/1000µs): 17.5A
• Power - Peak Pulse: 5000W
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Type: Zener, Bidirectional (1 channel)
• Operating Temperature Range: -55°C ~ 175°C
• RoHS Status: ROHS3 Compliant

The primary distinction between the main part and its substitute is the packaging format: the 5KP180CA-B is supplied in Bulk packaging, while the 5KP180CA substitute is supplied in Cut Tape (CT) format. Both parts are electrically and mechanically identical, with the packaging difference reflecting only the distribution method and inventory presentation.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP180CA-B and 5KP180CA are active production components from Littelfuse Inc. with identical electrical performance and mechanical specifications. Selection between these parts should be based on packaging requirements and supply chain considerations:

The 5KP180CA-B in Bulk packaging is suitable for high-volume manufacturing environments where components are handled in loose form and integrated into automated assembly processes. The 5KP180CA in Cut Tape (CT) format is appropriate for pick-and-place machine operations and applications requiring component-level traceability and controlled dispensing.

Both parts maintain full RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The unlimited moisture sensitivity rating (MSL 1) indicates no special storage or handling precautions are required beyond standard component storage practices.

Frequently Asked Questions (FAQ)

Q: Can the 5KP180CA (Cut Tape) be used as a direct replacement for the 5KP180CA-B (Bulk)?

A: Yes. Both parts are electrically and mechanically identical. The only difference is the packaging format. The Cut Tape version can be used in any application where the Bulk version was specified, provided the assembly process is compatible with tape-packaged components.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging supplies components in loose form, typically in bags or trays, suitable for manual handling or bulk feeding into assembly equipment. Cut Tape packaging supplies components on continuous carrier tape with individual component spacing, designed for automated pick-and-place machines. Both formats contain the same component with identical specifications.

Q: Are there any electrical performance differences between these parts?

A: No. Both the 5KP180CA-B and 5KP180CA have identical electrical characteristics: 180V reverse standoff voltage, 292V maximum clamping voltage, 17.5A peak pulse current, and 5kW peak pulse power rating.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which packaging format should I select for my application?

A: Select based on your assembly process. Use Bulk (5KP180CA-B) for manual assembly or bulk feeding systems. Use Cut Tape (5KP180CA) for automated pick-and-place assembly lines. Both are functionally equivalent for circuit design purposes.

Q: Can I mix these packaging formats in the same production run?

A: Yes, provided your assembly equipment can handle both formats. However, mixing packaging formats may complicate inventory management and traceability. Standardizing on one format per production batch is recommended for operational efficiency.
