Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP100CA is determined by matching the following critical electrical parameters:

• Voltage - Reverse Standoff: 100V (nominal)
• Voltage - Clamping (Max) @ Ipp: 162V
• Bidirectional channel configuration: 1 channel
• Type: Zener diode
• Mounting: Through-hole axial package
• Operating temperature range: -55°C to 175°C (TJ)
• Compliance: ROHS3 and REACH requirements

The 15KP100CA-TP from Micro Commercial Co meets these substitution criteria. While it features a higher peak pulse power rating (15000W versus 5000W) and different package designation (R-6 versus P600), the core voltage parameters, bidirectional configuration, temperature range, and compliance certifications align with the original specification. The increased power rating provides additional design margin without compromising compatibility in applications designed for the 5KP100CA.

Parameter Comparison

Engineering Selection Recommendations

The 15KP100CA-TP qualifies as a direct substitute for the 5KP100CA based on electrical equivalence and regulatory compliance. Both components maintain identical reverse standoff voltage (100V), clamping voltage (162V), and operating temperature specifications (-55°C to 175°C). Both are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

The 15KP100CA-TP features a higher peak pulse power rating (15000W versus 5000W), which represents a design advantage in applications where transient energy absorption capacity is a consideration. The axial through-hole mounting configuration is preserved, ensuring mechanical compatibility in existing PCB layouts designed for the 5KP100CA.

Selection between these parts should be based on availability, lead time, and cost considerations, as the electrical and mechanical specifications support interchangeability within the specified application envelope.

Frequently Asked Questions (FAQ)

Q: Can the 15KP100CA-TP replace the 5KP100CA in existing designs?

A: Yes. The 15KP100CA-TP maintains equivalent reverse standoff voltage (100V), clamping voltage (162V), and operating temperature range (-55°C to 175°C). Both components are through-hole axial packages and ROHS3 compliant. The higher power rating of the substitute part does not create compatibility issues.

Q: What is the significance of the different package designations (P600 versus R-6)?

A: Both designations refer to axial through-hole packages suitable for PCB mounting. The different naming conventions reflect manufacturer-specific package classifications. Physical compatibility for standard through-hole PCB layouts is maintained.

Q: Are there differences in peak pulse current specifications?

A: The 5KP100CA specifies 31.5A peak pulse current (10/1000µs). The 15KP100CA-TP does not provide this parameter in the available data. However, the equivalent clamping voltage and higher power rating indicate comparable or superior current handling capability.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 5KP100CA and 15KP100CA-TP are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What factors should drive the selection between these two parts?

A: Primary factors are availability, lead time, and cost. Electrical and mechanical specifications support direct substitution. The 15KP100CA-TP's higher power rating may provide additional design margin in applications with variable transient energy profiles.
