Equivalent & Substitute Parts for 5KP5.0-B

Part Overview

The 5KP5.0-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 with a 9.66V maximum clamping voltage and 5000W peak pulse power rating in a through-hole P600 axial package. The 5KP5.0-B is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 5KP5.0-B is determined by the following critical parameters that must remain consistent across equivalent parts:

• Voltage - Reverse Standoff: 5V (nominal)
• Voltage - Clamping (Max) @ Ipp: within acceptable tolerance range (9.2V to 9.66V)
• Power - Peak Pulse: 5000W (5kW)
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Type: Zener, Unidirectional (1 channel)

The substitute parts listed below meet these electrical and mechanical specifications, enabling direct functional replacement in circuit applications designed for the 5KP5.0-B.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (5KP5.0A, 5KP5.0A-B, and 5KP5.0E3/TR13) are active products with ROHS3 compliance and REACH unaffected status, making them suitable for new designs and production environments where the obsolete 5KP5.0-B is no longer available.

The 5KP5.0A and 5KP5.0A-B are functionally identical Littelfuse products differing only in packaging format (Cut Tape versus Bulk). Both maintain the same electrical specifications and are direct replacements from the original manufacturer.

The 5KP5.0E3/TR13 from Microchip Technology is a manufacturer-recommended alternative that meets all critical electrical parameters within acceptable tolerance. The clamping voltage of 9.6V is within the operational range of the original 5KP5.0-B specification.

Selection between these substitutes should be based on packaging requirements (tape and reel, cut tape, or bulk) and supplier availability rather than electrical performance, as all three parts satisfy the functional requirements of the 5KP5.0-B.

Frequently Asked Questions (FAQ)

Q: Can the 5KP5.0A directly replace the 5KP5.0-B in existing designs?

A: Yes. The 5KP5.0A maintains identical electrical specifications and the same P600 axial through-hole package, enabling direct substitution without circuit modification.

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

A: Both parts are electrically identical. The difference is packaging: 5KP5.0A is supplied in Cut Tape format, while 5KP5.0A-B is supplied in Bulk packaging. Selection depends on procurement and assembly requirements.

Q: Is the Microchip 5KP5.0E3/TR13 compatible with the original 5KP5.0-B?

A: Yes. The 5KP5.0E3/TR13 meets all critical electrical parameters including reverse standoff voltage (5V), clamping voltage (9.6V), peak pulse power (5000W), and operating temperature range (-55°C to 175°C). It is supplied in Tape & Reel packaging.

Q: Are there any compliance differences between the substitute parts?

A: No. All substitute parts carry ROHS3 compliance and REACH unaffected status, matching the original 5KP5.0-B specifications.

Q: What packaging options are available for substitutes?

A: The 5KP5.0A is available in Cut Tape (CT) packaging, the 5KP5.0A-B in Bulk packaging, and the 5KP5.0E3/TR13 in Tape & Reel (TR) packaging. All maintain the same P600 axial through-hole form factor.
