5KP110CA-G Equivalent & Substitute Parts

Part Overview

The 5KP110CA-G is a transient voltage suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection applications. This bidirectional Zener diode features a 110V reverse standoff voltage with a 177V maximum clamping voltage and 28.25A peak pulse current capability. The component is housed in an R-6 axial package and is rated for 5000W peak pulse power dissipation across an operating temperature range of -55°C to 150°C. The part maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified to provide design flexibility for procurement, inventory management, and application requirements where alternative packaging, performance ratings, or manufacturer specifications may be acceptable within the electrical and mechanical constraints of the application.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP110CA-G are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 110V
• Voltage - Breakdown (Min): 122V minimum
• Bidirectional Channels: 1
• Type: Zener
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: ±1.6V tolerance
• Current - Peak Pulse (10/1000µs): Equal or greater capacity
• Power - Peak Pulse: Equal or greater capacity
• Operating Temperature Range: Equal or extended range
• Package / Case: Alternative axial through-hole packages (R-6, P600)
• Packaging Format: Tape & Box, Bulk, or Cut Tape

Substitute parts must maintain identical voltage protection characteristics while permitting higher current and power ratings, extended temperature ranges, and alternative packaging formats.

Parameter Comparison

Engineering Selection Recommendations

5KP110CA (Littelfuse Inc.) is the primary direct substitute. This part maintains identical voltage protection parameters (110V standoff, 122V breakdown, 177V clamping) and equivalent current/power ratings (28.8A, 5000W). The Littelfuse variant offers an extended operating temperature range (-55 to 175°C versus -55 to 150°C) and is available in P600 axial packaging. Both the original 5KP110CA-G and this substitute are Active products with full ROHS3 compliance and unlimited moisture sensitivity rating.

15KPA110CA (MDE Semiconductor Inc.) qualifies as a higher-capacity substitute. This part maintains the same 110V voltage protection specification but provides significantly elevated current (84.5A) and power (15000W) ratings. The 15KPA110CA is suitable for applications requiring enhanced transient suppression capacity while maintaining identical voltage clamping characteristics. This part also features an extended operating temperature range (-55 to 175°C) and P600 axial packaging. REACH status information is available upon request from the manufacturer.

Both substitute parts are Active products with ROHS3 compliance. Selection between them depends on application transient current requirements and thermal management considerations.

Frequently Asked Questions (FAQ)

Q: Can the 15KPA110CA replace the 5KP110CA-G in all applications?

A: The 15KPA110CA maintains identical voltage protection parameters (110V standoff, 122V breakdown, 178.6V clamping) and is therefore electrically compatible. The higher current (84.5A) and power (15000W) ratings provide enhanced transient suppression capacity. Physical compatibility requires verification of board layout and mounting hole spacing, as the P600 package may differ from the R-6 package in physical dimensions.

Q: What is the difference between R-6 and P600 axial packages?

A: Both R-6 and P600 are axial through-hole packages formats for diodes. The primary differences are physical dimensions and lead spacing. Component selection must account for PCB layout, mounting hole positioning, and thermal dissipation requirements specific to the application.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 5KP110CA-G (Comchip), 5KP110CA (Littelfuse), and 15KPA110CA (MDE Semiconductor) are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the significance of the extended operating temperature range in the substitute parts?

A: The Littelfuse 5KP110CA and MDE Semiconductor 15KPA110CA both support -55 to 175°C operating temperature, compared to -55 to 150°C for the original 5KP110CA-G. Extended temperature range provides design margin for applications operating in elevated ambient or junction temperature conditions.

Q: Can packaging format be changed without affecting circuit performance?

A: Packaging format (Tape & Box, Bulk, Cut Tape) affects procurement and handling but does not alter electrical performance. However, physical package geometry (R-6 versus P600) must be verified for PCB compatibility, including lead spacing and mounting hole alignment.

Q: What inventory considerations apply to these substitutes?

A: The 5KP110CA-G has 820 units in stock, the Littelfuse 5KP110CA has 1165 units, and the MDE Semiconductor 15KPA110CA has 1792 units available. Substitute selection may be influenced by inventory availability and procurement lead times.
