5KP160CA-B Equivalent & Substitute Parts

Part Overview

The 5KP160CA-B is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This through-hole component operates across a temperature range of -55°C to 175°C and is RoHS3 compliant. The part is currently active in production with 1089 units in stock. Substitute parts may be required due to inventory constraints, packaging preferences, or application-specific voltage and current requirements within compatible electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP160CA-B are selected from the 1.5KE series manufactured by Taiwan Semiconductor Corporation. The substitution logic is based on the following criteria:

Electrical Compatibility Parameters:

• Bidirectional zener diode topology (1 channel)
• Through-hole axial mounting configuration
• Operating temperature range: -55°C to 175°C
• General-purpose transient voltage suppression applications
• RoHS3 compliance and REACH unaffected status

Voltage Selection Criteria: The substitute parts operate at different reverse standoff voltages (154V, 171V, and 185V) compared to the main part (160V). These alternatives provide clamping voltages ranging from 246V to 328V, accommodating applications requiring different voltage thresholds within the TVS diode category.

Current and Power Considerations: Substitute parts deliver reduced peak pulse currents (4.8A to 6.4A) and lower peak pulse power (1500W) compared to the 5KP160CA-B (19.7A, 5000W). Selection depends on circuit requirements for transient energy dissipation.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and RoHS3 compliance, ensuring regulatory alignment with the original 5KP160CA-B. The 1.5KE series alternatives are suitable for applications where the lower peak pulse power rating (1500W versus 5000W) and reduced peak pulse current (4.8A to 6.4A versus 19.7A) satisfy circuit protection requirements.

Selection between 1.5KE180CA, 1.5KE200CA, and 1.5KE220CA depends on the specific reverse standoff voltage and clamping voltage required by the protected circuit. The 1.5KE180CA provides the lowest clamping voltage (246V), while 1.5KE220CA provides the highest (328V). Package differences between P600 (main part) and DO-201AA/DO-27 (substitute parts) must be evaluated for PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1.5KE series parts directly replace the 5KP160CA-B in all applications?

A: Direct replacement depends on circuit requirements for peak pulse power and current. The 5KP160CA-B delivers 5000W peak pulse power and 19.7A peak pulse current, while 1.5KE series parts deliver 1500W and 4.8A to 6.4A respectively. Substitution is valid only when the application circuit requires equal or lower power and current dissipation.

Q: What is the difference between the three substitute part options?

A: The three 1.5KE variants differ in reverse standoff voltage and clamping voltage. 1.5KE180CA operates at 154V standoff with 246V clamping, 1.5KE200CA at 171V standoff with 274V clamping, and 1.5KE220CA at 185V standoff with 328V clamping. Selection is determined by the protected circuit's voltage protection threshold.

Q: Are there package compatibility concerns between the main part and substitutes?

A: Yes. The 5KP160CA-B uses P600 axial package, while all 1.5KE substitutes use DO-201AA/DO-27 axial package. Both are through-hole axial configurations, but physical dimensions differ. PCB footprint verification is required before substitution.

Q: Do all parts share the same operating temperature range?

A: Yes. The 5KP160CA-B and all three 1.5KE substitute parts operate across -55°C to 175°C junction temperature, ensuring thermal compatibility.

Q: Are regulatory certifications equivalent across all parts?

A: Yes. All parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8541.10.0080, ensuring equivalent regulatory status.
