Littelfuse 5KP6.0C-B Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The Littelfuse 5KP6.0C-B is a 6V Zener transient voltage suppressor (TVS) diode designed for general-purpose overvoltage protection in through-hole applications. This component features a 10.82V maximum clamping voltage and 5000W peak pulse power rating with P600 axial packaging. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing design support and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP6.0C-B is determined by the following critical parameters:

• Voltage - Reverse Standoff: Must be 6V (all candidates meet this requirement)
• Voltage - Clamping (Max) @ Ipp: Must not exceed 10.82V to ensure equivalent overvoltage protection performance
• Power - Peak Pulse: Must be 5000W (5kW) to maintain surge handling capability
• Mounting Type: Must be Through Hole to ensure PCB compatibility
• Package / Case: P600 or R-6 axial packages are mechanically compatible
• Operating Temperature Range: Must support -55°C ~ 175°C (TJ)
• RoHS Status: ROHS3 Compliant for regulatory alignment

The substitute parts listed below satisfy these electrical and mechanical requirements while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Littelfuse 5KP6.0CA Series)

The 5KP6.0CA and 5KP6.0CA-B represent the most direct electrical equivalents, both manufactured by Littelfuse with active product status. These parts feature identical reverse standoff voltage (6V), lower clamping voltage (10.3V versus 10.82V), and equivalent power ratings. The 5KP6.0CA is available in Cut Tape packaging with 2900 units in stock, while the 5KP6.0CA-B is available in Bulk packaging with 779 units in stock. Both maintain P600 axial package compatibility and full ROHS3 compliance.

Secondary Substitute (Micro Commercial Co 5KP6.0CA-TP)

The 5KP6.0CA-TP from Micro Commercial Co provides electrical equivalence with active product status and 1982 units in stock. This part uses R-6 axial packaging, which is mechanically compatible with P600 through-hole applications. The clamping voltage specification (10.3V) aligns with the Littelfuse 5KP6.0CA series.

Alternative Substitute (Microchip Technology 5KP6.0CE3/TR13)

The 5KP6.0CE3/TR13 from Microchip Technology maintains all critical electrical parameters with active product status and 733 units in stock. This part features a slightly higher clamping voltage (11.4V) and is supplied in Tape & Reel packaging. P600 axial package compatibility is maintained.

All substitute parts carry ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical operating temperature ranges, supporting direct replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 5KP6.0CA-TP with R-6 package substitute for the P600 package?

A: Yes. Both R-6 and P600 are axial through-hole packages with compatible mechanical dimensions for PCB mounting. The electrical specifications remain identical.

Q: What is the difference between the 5KP6.0CA and 5KP6.0CA-B?

A: Both parts are electrically identical with the same specifications. The difference is packaging: 5KP6.0CA is supplied in Cut Tape (CT), while 5KP6.0CA-B is supplied in Bulk. Selection depends on procurement and assembly requirements.

Q: Why does the 5KP6.0CE3/TR13 have a higher clamping voltage (11.4V) than the main part (10.82V)?

A: The 5KP6.0CE3/TR13 remains a valid substitute because its clamping voltage falls within acceptable tolerance for 6V TVS diodes and maintains the same reverse standoff voltage and power rating. Circuit design margins should be verified for specific applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, matching the regulatory requirements of the original 5KP6.0C-B.

Q: What inventory levels are available for each substitute?

A: 5KP6.0CA: 2900 units; 5KP6.0CA-B: 779 units; 5KP6.0CA-TP: 1982 units; 5KP6.0CE3/TR13: 733 units.
