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

Part Overview

The Littelfuse 5KP6.0C 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. The 5KP6.0C is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across reverse standoff voltage, clamping characteristics, and power dissipation specifications while accommodating packaging variations.

Engineering Selection Recommendations

Primary Substitute: 5KP6.0CA (Littelfuse Inc.)

The 5KP6.0C can be directly replaced with the 5KP6.0CA. Both parts are manufactured by Littelfuse Inc., share identical reverse standoff voltage (6V) and peak pulse power (5000W), and maintain the same P600 axial package configuration. The 5KP6.0CA is in active production status, ensuring long-term availability. The clamping voltage differential (10.3V vs. 10.82V) falls within acceptable substitution tolerance for general-purpose transient suppression applications. ROHS3 compliance and MSL 1 rating are maintained.

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

The 5KP6.0CE3/TR13 provides functional equivalence with identical reverse standoff voltage and peak pulse power specifications. This part maintains P600 axial packaging and ROHS3 compliance. The clamping voltage is 11.4V, representing a 0.58V increase relative to the main part. This part is supplied in Tape & Reel format, suitable for automated assembly environments. Active production status ensures availability.

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

The 5KP6.0CA-TP offers electrical equivalence with 6V reverse standoff voltage and 5000W peak pulse power. This part uses R-6 axial packaging instead of P600, requiring mechanical board layout verification. Cut Tape packaging format is suitable for manual or semi-automated assembly. Active production status is confirmed. ROHS3 compliance and MSL 1 rating apply.

All three substitute parts maintain compliance certifications (ROHS3, EAR99, HTSUS 8541.10.0080) and operating temperature range (-55°C to 175°C TJ) required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the 5KP6.0C be replaced with any of these substitute parts in existing designs?

A: Yes. All three substitute parts (5KP6.0CA, 5KP6.0CE3/TR13, and 5KP6.0CA-TP) meet the electrical requirements for direct substitution. The 5KP6.0CA is the most direct replacement due to identical packaging (P600). The 5KP6.0CA-TP requires mechanical verification due to R-6 package differences.

Q: What is the significance of the clamping voltage differences between parts?

A: The main part specifies 10.82V maximum clamping voltage. Substitute parts range from 10.3V to 11.4V. These variations remain within acceptable tolerance for general-purpose transient suppression. Selection should be based on specific circuit protection requirements and maximum allowable clamping voltage limits in the application.

Q: Are there packaging format considerations for substitution?

A: Yes. The 5KP6.0C and 5KP6.0CA use P600 axial packaging. The 5KP6.0CE3/TR13 is supplied in Tape & Reel format, suitable for high-volume automated assembly. The 5KP6.0CA-TP uses R-6 axial packaging, which may require board layout modification. Verify mechanical compatibility before implementation.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. ECCN and HTSUS classifications are identical across all parts, ensuring regulatory equivalence.

Q: Why is the 5KP6.0C classified as obsolete?

A: The 5KP6.0C is no longer in active production. The active equivalents (5KP6.0CA, 5KP6.0CE3/TR13, and 5KP6.0CA-TP) provide identical electrical performance and are recommended for new designs and production continuity.

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

A: Cut Tape (CT) packaging is suitable for manual or semi-automated assembly with smaller order quantities. Tape & Reel (TR) packaging is optimized for high-volume automated pick-and-place assembly. Both formats contain identical components; selection depends on assembly process requirements.
