5KP110CA-B Equivalent & Substitute Parts

Part Overview

The 5KP110CA-B is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage protection applications. This through-hole component operates with a reverse standoff voltage of 110V and provides peak pulse power dissipation of 5000W. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when packaging or inventory requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP110CA-B is determined by strict equivalence across the following critical 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
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature Range: -55°C to 175°C (TJ)
• RoHS Status: ROHS3 Compliant

The 5KP110CA substitute part maintains identical electrical performance and mechanical specifications. The distinction between the main part and substitute is limited to packaging format: the main part (5KP110CA-B) is supplied in Bulk packaging, while the substitute (5KP110CA) is supplied in Cut Tape (CT) packaging. Both parts are manufactured by Littelfuse Inc. within the active 5KP series and meet all compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP110CA-B and 5KP110CA are active production components from Littelfuse Inc. with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is based on packaging and inventory requirements rather than electrical or mechanical performance differences.

The 5KP110CA-B in Bulk packaging is suitable for high-volume manufacturing environments where components are supplied in loose form for automated assembly processes. The 5KP110CA in Cut Tape (CT) packaging is appropriate for applications requiring tape-and-reel format for pick-and-place equipment or lower-volume production runs.

Both parts are functionally interchangeable in circuit applications requiring 110V reverse standoff protection with 5000W peak pulse power dissipation in the P600 axial through-hole package.

Frequently Asked Questions (FAQ)

Q: Are the 5KP110CA-B and 5KP110CA electrically identical?

A: Yes. Both parts share identical electrical specifications including 110V reverse standoff voltage, 122V minimum breakdown voltage, 177V maximum clamping voltage, 28.8A peak pulse current, and 5000W peak pulse power rating.

Q: What is the difference between Bulk and Cut Tape (CT) packaging?

A: Bulk packaging supplies components in loose form, typically used in high-volume manufacturing with automated handling systems. Cut Tape (CT) packaging supplies components on continuous tape in reels, designed for automated pick-and-place equipment. Both formats contain the same component.

Q: Can I use 5KP110CA in place of 5KP110CA-B in my circuit design?

A: Yes. The 5KP110CA is a direct substitute for the 5KP110CA-B. The only difference is packaging format. Circuit performance and specifications remain identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the 5KP110CA-B and 5KP110CA are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the operating temperature range for these TVS diodes?

A: Both parts operate across -55°C to 175°C junction temperature range, suitable for industrial and commercial applications.

Q: Are these parts suitable for power line protection applications?

A: No. Both the 5KP110CA-B and 5KP110CA are classified for general-purpose transient voltage suppression, not power line protection applications.
