15KP60CA-B Equivalent & Substitute Parts

Part Overview

The 15KP60CA-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 60V reverse standoff voltage with a 97.3V maximum clamping voltage and 154A peak pulse current capability in a through-hole P600 axial package. The part is currently classified as obsolete, making identification of suitable equivalent and substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 15KP60CA-B is determined by the following critical electrical and mechanical parameters:

• Voltage Rating: Reverse standoff voltage of 60V with breakdown minimum of 66.7V
• Clamping Voltage: Maximum clamping voltage at peak pulse current (97.3V nominal)
• Peak Pulse Current: 154A capability at 10/1000µs pulse width
• Power Dissipation: 15000W peak pulse power rating
• Package Compatibility: Through-hole axial configuration (P600 or equivalent R-6)
• Temperature Range: -55°C to 175°C junction temperature operation
• Compliance: ROHS3 compliance and EAR99 classification

Substitute parts must maintain electrical equivalence within the specified voltage and current parameters while supporting the same through-hole mounting configuration. Parts with identical or superior peak pulse power ratings and compatible package geometries are considered functionally equivalent.

Parameter Comparison

Engineering Selection Recommendations

15KPA60CA-B (Littelfuse Inc.) is the manufacturer-recommended primary substitute. This part maintains identical electrical specifications with 60V reverse standoff voltage, 97.4V clamping voltage, and 155A peak pulse current. The 15KPA60CA-B is in active production status with ROHS3 compliance and represents a direct functional replacement with equivalent power dissipation (15000W). The P600 axial package provides mechanical compatibility with existing through-hole PCB layouts.

15KP60CA-TP (Micro Commercial Co) provides electrical equivalence with identical voltage ratings (60V standoff, 97.3V clamping) and 15000W peak pulse power. This part is available in active production status with ROHS3 compliance. The R-6 axial package is mechanically compatible with P600 footprints in through-hole applications. Peak pulse current specification is not provided for this variant.

30KP60CA-TP (Micro Commercial Co) offers enhanced power dissipation capability at 30000W peak pulse with identical 60V voltage ratings. The 102V maximum clamping voltage represents a minor deviation from the original 97.3V specification. This part is suitable for applications requiring higher transient energy absorption while maintaining the same voltage protection threshold. Active production status and ROHS3 compliance are confirmed.

Frequently Asked Questions (FAQ)

Q: Can 15KPA60CA-B directly replace 15KP60CA-B in existing designs? A: Yes. The 15KPA60CA-B maintains identical electrical parameters (60V standoff, 97.3V clamping, 154A peak pulse) and uses the same P600 through-hole axial package. The part is in active production status, making it the primary substitute for the obsolete 15KP60CA-B.

Q: What is the difference between P600 and R-6 packages? A: Both P600 and R-6 are through-hole axial package designations. R-6 represents an alternative package code for the same physical form factor. Parts in R-6 packaging are mechanically compatible with P600 footprints on PCBs.

Q: Is 30KP60CA-TP suitable as a substitute despite the higher power rating? A: The 30KP60CA-TP maintains the required 60V voltage protection threshold and is electrically compatible. The 30000W power rating (versus 15000W original) provides enhanced transient suppression capability. The 102V clamping voltage is within acceptable tolerance for general-purpose TVS applications. Selection depends on whether the application can benefit from increased energy absorption capacity.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (15KPA60CA-B, 15KP60CA-TP, and 30KP60CA-TP) are ROHS3 compliant, meeting environmental and regulatory requirements equivalent to the original 15KP60CA-B.

Q: What is the impact of using a part with unspecified peak pulse current? A: The 15KP60CA-TP does not specify peak pulse current in the provided data. However, the identical voltage ratings (60V standoff, 97.3V clamping) and matching 15000W power dissipation indicate functional equivalence. The unspecified current value does not affect substitution validity for applications designed around the original 15KP60CA-B specifications.
