5KP60C Equivalent & Substitute Parts

Part Overview

The 5KP60C is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This part operates with a 60V reverse standoff voltage and delivers 5000W peak pulse power in a through-hole P600 axial package. The 5KP60C is currently listed as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Substitute parts are grouped into two categories based on package compatibility:

Category A - P600 Axial Package (Direct Mechanical Fit):

5KP60CA (Littelfuse Inc.)
SLD60-018-B (Littelfuse Inc.)
5KP60CE3/TR13 (Microchip Technology)

Category B - R-6 Axial Package (Mechanical Variation):

15KP60CA-TP (Micro Commercial Co)
30KP60CA-TP (Micro Commercial Co)

All listed substitutes meet the core electrical requirements and compliance standards of the obsolete 5KP60C.

Engineering Selection Recommendations

For Direct Replacement (P600 Package):

5KP60CA is the primary active substitute from Littelfuse Inc., maintaining identical package geometry and electrical specifications. This part is in active production status with 4700 units in stock, providing supply continuity for the obsolete 5KP60C.

SLD60-018-B is an automotive-grade alternative from Littelfuse Inc., qualified to AEC-Q101 standard. This part maintains P600 package compatibility and identical clamping voltage characteristics. Selection of this part is appropriate for applications requiring automotive-grade qualification.

5KP60CE3/TR13 from Microchip Technology is available in P600 package with identical power rating. This part exhibits a higher clamping voltage (107V) compared to the original 5KP60C (101.64V), which may be acceptable depending on circuit design margins.

For Higher Power Applications (R-6 Package):

15KP60CA-TP and 30KP60CA-TP from Micro Commercial Co provide 15kW and 30kW peak pulse power respectively, exceeding the 5kW specification of the 5KP60C. These parts use the R-6 axial package, which differs mechanically from the P600 package. Selection of these parts requires board layout modification to accommodate the different package footprint.

All substitute parts maintain ROHS3 compliance and the full operating temperature range of the original part.

Frequently Asked Questions (FAQ)

Q: Can 5KP60CA directly replace 5KP60C without board modifications?

A: Yes. The 5KP60CA maintains identical P600 axial package geometry, mounting type, and electrical specifications. No board layout changes are required.

Q: What is the difference between P600 and R-6 packages?

A: Both are through-hole axial packages for TVS diodes. P600 and R-6 differ in physical dimensions and lead spacing. Parts using R-6 package (15KP60CA-TP, 30KP60CA-TP) require different board footprints than P600 parts.

Q: Why do some substitutes have higher power ratings (15kW, 30kW)?

A: Higher power-rated parts provide additional transient energy absorption capability. These are suitable for applications requiring greater overvoltage protection margin. The 5kW minimum requirement of the original 5KP60C is met by all listed substitutes.

Q: Is SLD60-018-B suitable for non-automotive applications?

A: Yes. SLD60-018-B is automotive-qualified but functions as a general-purpose TVS diode. Automotive qualification does not restrict use in non-automotive circuits.

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

A: Clamping voltage determines the maximum voltage the TVS diode allows across the protected circuit during transient events. Substitutes with higher clamping voltages (5KP60CE3/TR13 at 107V vs. 5KP60C at 101.64V) provide less aggressive clamping. Circuit design margins must accommodate these differences.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the environmental standard of the original 5KP60C.

Q: Which substitute offers the best supply availability?

A: 5KP60CA has 4700 units in stock, providing the highest immediate availability among all substitutes.
