5KP14CA-B Equivalent & Substitute Parts

Part Overview

The 5KP14CA-B is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This through-hole component features a 14V reverse standoff voltage and 5000W peak pulse power rating, making it suitable for protecting sensitive electronic circuits from transient voltage events. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity level rating.

Identifying equivalent and substitute parts is necessary when the original packaging format (Bulk) is unavailable, when alternative sourcing is required, or when design flexibility permits component standardization across procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP14CA-B is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 14V
• Voltage - Breakdown (Min): 15.6V
• Voltage - Clamping (Max) @ Ipp: 23.2V
• Current - Peak Pulse (10/1000µs): 219.8A
• Power - Peak Pulse: 5000W (5kW)
• Bidirectional Channels: 1
• Package / Case: P600, Axial
• Mounting Type: Through Hole

The 5KP14CA qualifies as a direct substitute based on identical electrical specifications and mechanical form factor. The only difference is the packaging format: the main part (5KP14CA-B) is supplied in Bulk packaging, while the substitute (5KP14CA) is supplied in Cut Tape (CT) packaging. Both parts share the same base product number (5KP1) and series designation, confirming functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP14CA-B and 5KP14CA are manufactured by Littelfuse Inc. and maintain active product status. Both parts carry full ROHS3 compliance and are unaffected by REACH regulations, meeting current environmental and regulatory requirements for electronic component procurement.

The selection between these parts is determined by packaging and supply chain requirements rather than electrical or mechanical performance. The 5KP14CA-B in Bulk packaging is suitable for high-volume manufacturing environments with integrated component handling systems. The 5KP14CA in Cut Tape (CT) packaging is appropriate for automated pick-and-place assembly processes and lower-volume production runs.

Both parts are classified under ECCN EAR99 and HTSUS 8541.10.0080, confirming identical export control and tariff classification.

Frequently Asked Questions (FAQ)

Q: Can 5KP14CA (Cut Tape) be used as a direct replacement for 5KP14CA-B (Bulk)?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. Cut Tape packaging is compatible with automated assembly equipment, while Bulk packaging is suited for manual or high-volume integrated handling systems.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts share identical voltage ratings (14V reverse standoff, 15.6V breakdown minimum, 23.2V clamping maximum), current specifications (219.8A peak pulse), and power ratings (5000W peak pulse). Operating temperature range and all other electrical parameters are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both 5KP14CA-B and 5KP14CA are ROHS3 compliant, REACH unaffected, and carry the same MSL rating of 1 (Unlimited). They share identical ECCN and HTSUS classifications.

Q: What is the physical difference between P600 Bulk and P600 Cut Tape packaging?

A: Both use the P600 axial through-hole package form factor. The difference is in the carrier format: Bulk packaging supplies loose components, while Cut Tape packaging supplies components on a continuous tape suitable for automated feeder systems.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process can accommodate the packaging format. Cut Tape parts integrate directly with standard tape feeders on pick-and-place machines. Bulk parts require manual placement or integration with bulk component handling systems.
