Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP10CA-B are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 10V
• Voltage - Breakdown (Min): 11.1V
• Voltage - Clamping (Max) @ Ipp: 17V
• Power - Peak Pulse: 5000W (5kW)
• Bidirectional Channels: 1
• Type: Zener
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• RoHS Status: ROHS3 Compliant
• Mounting Type: Through Hole

Packaging Variations: Substitute parts may differ in packaging format (Bulk vs. Cut Tape) and package case designation (P600 vs. R-6 axial packages), provided all electrical parameters remain within specification.

The identified substitutes are 5KP10CA and 5KP10CA-TP, both meeting the electrical requirements while offering different packaging and supplier options.

Parameter Comparison

Engineering Selection Recommendations

5KP10CA (Littelfuse Inc.): This substitute maintains identical electrical specifications and operating parameters to the 5KP10CA-B. The primary difference is packaging format (Cut Tape vs. Bulk), making it suitable for automated assembly processes. Both parts are manufactured by Littelfuse Inc., ensuring consistent quality and performance characteristics. ROHS3 compliance and MSL rating are equivalent.

5KP10CA-TP (Micro Commercial Co): This substitute meets all critical voltage and power specifications with identical clamping voltage (17V) and power dissipation (5000W). The component is supplied by Micro Commercial Co in Cut Tape format with R-6 axial package designation. Peak pulse current specification is not provided for this part. ROHS3 compliance and operating temperature range match the main part. Physical package dimensions differ (R-6 vs. P600), requiring verification of PCB layout compatibility.

All three parts maintain active product status and full regulatory compliance, supporting long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can 5KP10CA be used as a direct replacement for 5KP10CA-B? A: Yes. The 5KP10CA is electrically and functionally identical to the 5KP10CA-B. The difference is packaging format: 5KP10CA-B is supplied in Bulk, while 5KP10CA is supplied in Cut Tape. Both are manufactured by Littelfuse Inc. and meet identical electrical specifications.

Q: What is the difference between P600 and R-6 package designations? A: Both are axial through-hole packages for TVS diodes. P600 and R-6 represent different physical package dimensions and lead configurations. PCB layout and component placement must accommodate the specific package type. Verify mechanical compatibility before substitution.

Q: Is 5KP10CA-TP suitable for applications requiring 300A peak pulse current? A: The 5KP10CA-TP datasheet does not specify peak pulse current. While power dissipation (5000W) and voltage parameters match, the absence of current specification requires verification against application requirements before selection.

Q: Are all three parts ROHS3 compliant? A: Yes. The 5KP10CA-B, 5KP10CA, and 5KP10CA-TP are all ROHS3 compliant with MSL rating of 1 (Unlimited), meeting modern environmental and regulatory standards.

Q: What factors should determine which substitute to select? A: Selection depends on packaging requirements (Bulk vs. Cut Tape), supplier preference, inventory availability, and physical package compatibility (P600 vs. R-6). All three parts meet identical electrical specifications for general-purpose transient voltage suppression applications.
