5KP110C-B Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 5KP110C-B is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Littelfuse, designed for general-purpose overvoltage protection applications. This component features a 110V reverse standoff voltage with 177V maximum clamping voltage and 28.8A peak pulse current capability in a through-hole P600 axial package. The 5KP110C-B is classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP110C-B is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 110V
• Voltage - Breakdown (Min): 122V
• Voltage - Clamping (Max) @ Ipp: 177V
• Current - Peak Pulse (10/1000µs): 28.8A
• Power - Peak Pulse: 5000W (5kW)
• Bidirectional Channels: 1
• Type: Zener
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature Range: -55°C ~ 175°C (TJ)

The substitute parts identified below maintain identical electrical performance specifications and mechanical compatibility. Differences in packaging format (Cut Tape vs. Bulk) and product status (Active vs. Obsolete) do not affect functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both 5KP110CA and 5KP110CA-B are direct functional equivalents to the obsolete 5KP110C-B. Selection between these active alternatives is based on procurement and assembly requirements:

5KP110CA (Cut Tape Packaging): Suitable for automated pick-and-place assembly processes and high-volume production environments where tape-and-reel format is standard.

5KP110CA-B (Bulk Packaging): Appropriate for manual assembly, repair operations, and applications where individual component handling is required.

Both substitute parts maintain full electrical and thermal equivalence with identical voltage ratings, current handling, power dissipation, and operating temperature specifications. Both are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can 5KP110CA and 5KP110CA-B be used interchangeably with 5KP110C-B?

A: Yes. Both parts are electrically and mechanically identical to the 5KP110C-B across all critical parameters: 110V reverse standoff voltage, 177V clamping voltage, 28.8A peak pulse current, 5000W peak power, P600 axial through-hole package, and -55°C to 175°C operating temperature range. The only differences are packaging format and product status (both substitutes are active).

Q: What is the difference between 5KP110CA and 5KP110CA-B?

A: The electrical and mechanical specifications are identical. The difference is packaging format: 5KP110CA is supplied in Cut Tape (CT) format for automated assembly, while 5KP110CA-B is supplied in Bulk format for manual handling and repair applications.

Q: Why is the 5KP110C-B classified as obsolete?

A: Product obsolescence is determined by the manufacturer. The active equivalents 5KP110CA and 5KP110CA-B provide identical functionality and should be used for new designs and production.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts are ROHS3 compliant with MSL 1 rating. Compliance certifications are identical.

Q: Can these parts be soldered using standard through-hole assembly processes?

A: Yes. All three parts use the P600 axial through-hole package and are compatible with standard wave soldering and manual soldering processes.

Q: What is the base product number for this series?

A: The base product number is 5KP1, which identifies the 5KP series of transient voltage suppressors from Littelfuse.
