Equivalent & Substitute Parts for 5KP5.0C TVS Diode

Part Overview

The 5KP5.0C is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This bidirectional Zener diode features a 5V reverse standoff voltage and 9.66V maximum clamping voltage with 5000W peak pulse power handling capability in a through-hole P600 axial package.

The 5KP5.0C is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP5.0C is determined by the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Clamping (Max) @ Ipp: Within acceptable tolerance range (9.2V to 9.66V)
• Power - Peak Pulse: 5000W (5kW)
• Bidirectional Channels: 1
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Mounting Type: Through Hole
• Package / Case: P600 or equivalent axial package (R-6 acceptable)
• Type: Zener
• RoHS Status: ROHS3 Compliant

Three substitute parts meet these criteria and are available as active products from authorized manufacturers.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with ROHS3 compliance and identical operating temperature ranges. Selection should be based on the following factors:

5KP5.0CA (Littelfuse Inc.): Direct manufacturer equivalent with identical P600 axial package. Clamping voltage of 9.2V is lower than the original 9.66V specification. Active product status ensures long-term availability and supply chain continuity.

5KP5.0CA-TP (Micro Commercial Co): Functionally equivalent with identical electrical specifications to 5KP5.0CA. Package designation R-6 is mechanically compatible with P600 axial footprints. Active product status supports ongoing procurement.

5KP5.0CE3/TR13 (Microchip Technology): Clamping voltage of 9.6V closely matches the original 9.66V specification. Supplied in Tape & Reel format rather than Cut Tape. Active product status ensures availability. P600 axial package maintains mechanical compatibility.

Frequently Asked Questions (FAQ)

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

A: Yes. The 5KP5.0CA meets all critical electrical parameters: 5V reverse standoff voltage, 5000W peak pulse power, identical operating temperature range, and P600 axial package. The clamping voltage difference (9.2V vs. 9.66V) remains within the functional tolerance for general-purpose transient voltage suppression applications.

Q: What is the difference between the R-6 and P600 packages?

A: Both R-6 and P600 are axial through-hole packages designations for TVS diodes. The 5KP5.0CA-TP uses R-6 designation while maintaining mechanical and electrical compatibility with P600 footprints in circuit board designs.

Q: Why does 5KP5.0CE3/TR13 have a different clamping voltage?

A: The 5KP5.0CE3/TR13 clamping voltage of 9.6V is within the acceptable range for this product category and meets the 5V reverse standoff requirement. The 0.06V difference from the original 9.66V specification does not affect functional performance in general-purpose overvoltage protection circuits.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging provides individual components on tape segments suitable for manual handling and small-quantity assembly. Tape & Reel (TR) packaging supplies components on continuous reels for automated pick-and-place assembly equipment. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three substitute parts carry ROHS3 Compliant certification, matching the compliance status of the original 5KP5.0C component.

Q: Can I mix substitute parts in the same production run?

A: Yes. All three substitute parts meet identical electrical specifications for reverse standoff voltage, peak pulse power, operating temperature range, and bidirectional channel configuration. Mechanical compatibility is maintained across all three options for through-hole P600 and R-6 axial packages.
