5KP12CA-G Equivalent & Substitute Parts

Part Overview

The 5KP12CA-G is a Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose transient voltage protection applications. This bidirectional Zener diode operates with a 12V reverse standoff voltage and provides peak pulse power handling of 5000W. The component is classified as Active product status and is ROHS3 compliant, making it suitable for modern electronic circuit protection requirements. Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and optimize procurement across different packaging formats and manufacturer options.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP12CA-G is determined by the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 12V
• Voltage - Breakdown (Min): 13.3V
• Voltage - Clamping (Max) @ Ipp: 19.9V
• Current - Peak Pulse (10/1000µs): ≥ 251.26A
• Power - Peak Pulse: 5000W (5kW)
• Bidirectional Channels: 1
• Type: Zener

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: R-6 or equivalent axial package
• Operating Temperature Range: -55°C minimum to 150°C minimum

Substitute parts must maintain identical electrical performance specifications and support the same through-hole mounting configuration. Packaging format variations (Tape & Box vs. Cut Tape) do not affect electrical equivalence but may impact procurement and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

A5KP12CA-G (Direct Substitute - Comchip Technology): This part is electrically and mechanically identical to the 5KP12CA-G, with the primary difference being packaging format (Cut Tape vs. Tape & Box). Both are manufactured by Comchip Technology and maintain identical electrical specifications. Selection of A5KP12CA-G is appropriate when Cut Tape packaging aligns with assembly process requirements. Both parts are Active status and ROHS3 compliant.

5KP12CA (MFR Recommended - Littelfuse Inc.): This part meets all electrical equivalence criteria with marginally higher peak pulse current (256.3A vs. 251.26A) and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 150°C). The package format differs (P600 vs. R-6 axial), requiring mechanical verification for PCB footprint compatibility. This part is Active status and ROHS3 compliant. Selection is appropriate when higher temperature performance or increased current margin is required and mechanical compatibility is confirmed.

Frequently Asked Questions (FAQ)

Q: Can A5KP12CA-G be used as a direct replacement for 5KP12CA-G? A: Yes. Both parts are manufactured by Comchip Technology with identical electrical specifications (12V standoff, 19.9V clamping, 251.26A peak pulse, 5000W power). The difference is packaging format: A5KP12CA-G uses Cut Tape while 5KP12CA-G uses Tape & Box. Electrical performance and through-hole mounting are equivalent.

Q: Is the Littelfuse 5KP12CA compatible with the Comchip 5KP12CA-G? A: Electrically, yes. The Littelfuse part meets all voltage and power specifications with slightly higher peak pulse current (256.3A). However, the package format differs (P600 vs. R-6 axial). Mechanical compatibility must be verified against PCB footprint requirements before selection.

Q: What are the critical parameters for TVS diode substitution? A: Reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and power rating must match or exceed the original specification. Mounting type (through-hole) and operating temperature range must also be compatible with the application.

Q: Does packaging format affect electrical performance? A: No. Packaging format (Tape & Box, Cut Tape, or different axial packages) does not affect electrical performance. Selection is based on assembly process requirements and PCB footprint compatibility.

Q: Are all listed parts ROHS3 compliant? A: Yes. The 5KP12CA-G, A5KP12CA-G, and 5KP12CA are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
