5KP5.0C-B Equivalent & Substitute Parts

Part Overview

The 5KP5.0C-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 5V reverse standoff voltage, 9.66V maximum clamping voltage, and 5000W peak pulse power rating in a through-hole P600 axial package. The part is currently obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP5.0C-B is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): Must be 5V
• Power - Peak Pulse: Must be 5000W (5kW)
• Voltage - Clamping (Max) @ Ipp: Must be within acceptable range (9.2V to 9.66V)
• Operating Temperature Range: Must support -55°C ~ 175°C (TJ)
• Mounting Type: Must be Through Hole
• Package / Case: Must be P600 or R-6 axial configuration
• Type: Must be Zener diode
• Bidirectional Channels: Must be 1

Substitute parts are grouped into two categories: direct Littelfuse equivalents with identical electrical characteristics and packaging, and manufacturer-recommended alternatives from Micro Commercial Co and Microchip Technology that meet the same electrical specifications with compatible package configurations.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Littelfuse Inc.)

The 5KP5.0CA and 5KP5.0CA-B are direct Littelfuse equivalents with active product status. Both maintain identical electrical specifications including 5V reverse standoff voltage, 5000W peak pulse power, and P600 axial package configuration. The 5KP5.0CA is supplied in cut tape packaging, while 5KP5.0CA-B is supplied in bulk. These parts are functionally interchangeable with the obsolete 5KP5.0C-B and represent the preferred substitution path for design continuity within the Littelfuse 5KP series.

Secondary Substitutes (Cross-Manufacturer)

The 5KP5.0CA-TP (Micro Commercial Co) and 5KP5.0CE3/TR13 (Microchip Technology) are manufacturer-recommended alternatives that meet all critical electrical parameters. The 5KP5.0CA-TP uses an R-6 axial package instead of P600, requiring mechanical verification for board layout compatibility. The 5KP5.0CE3/TR13 maintains P600 package compatibility and is supplied on tape and reel. Both alternatives are ROHS3 compliant and support the full operating temperature range.

All substitute parts maintain compliance with ROHS3 and EAR99 export classification, ensuring regulatory continuity for applications requiring the 5KP5.0C-B.

Frequently Asked Questions (FAQ)

Q: Can I use 5KP5.0CA as a direct replacement for 5KP5.0C-B?

A: Yes. The 5KP5.0CA maintains identical electrical specifications (5V reverse standoff, 9.2V clamping voltage, 5000W peak pulse power) and P600 axial package configuration. The primary difference is product status (active vs. obsolete) and packaging format (cut tape vs. bulk).

Q: What is the difference between 5KP5.0CA and 5KP5.0CA-B?

A: Both parts are electrically identical. The difference is packaging: 5KP5.0CA is supplied in cut tape (CT), while 5KP5.0CA-B is supplied in bulk. Selection depends on procurement and assembly requirements.

Q: Can I use 5KP5.0CA-TP as a substitute?

A: The 5KP5.0CA-TP meets all electrical requirements but uses an R-6 axial package instead of P600. Physical dimensions and lead spacing differ. Mechanical compatibility with existing board layouts must be verified before substitution.

Q: How does the 5KP5.0CE3/TR13 compare to the original 5KP5.0C-B?

A: The 5KP5.0CE3/TR13 (Microchip Technology) maintains P600 package compatibility and meets all electrical specifications. The clamping voltage is 9.6V compared to 9.66V in the original part, which is within acceptable tolerance for general-purpose TVS applications. This part is supplied on tape and reel.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (5KP5.0CA, 5KP5.0CA-B, 5KP5.0CA-TP, and 5KP5.0CE3/TR13) are ROHS3 compliant with moisture sensitivity level 1 (unlimited).

Q: What is the key parameter that determines substitutability?

A: The critical parameters are 5V reverse standoff voltage, 5000W peak pulse power rating, and through-hole axial package configuration. Clamping voltage must remain within 9.2V to 9.66V range. All substitute parts meet these requirements.
