5KP5.0CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP5.0CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This bidirectional Zener diode features a 5V reverse standoff voltage with a 9.6V maximum clamping voltage and peak pulse current rating of 521A. The component is supplied in Tape & Reel packaging with Through Hole P600 axial mounting. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1). Substitute parts are identified to provide alternative sourcing options where packaging format, clamping voltage tolerance, or peak pulse current specifications permit functional equivalence within the same application category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP5.0CE3/TR13 are qualified based on the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Breakdown (Min): 6.4V
• Power - Peak Pulse: 5000W (5kW)
• Operating Temperature Range: -55°C to 175°C (TJ)
• Type: Zener, Bidirectional, Single Channel

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: P600 or R-6 Axial configurations

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts may vary in clamping voltage (within 9.2V to 9.6V range) and peak pulse current (within 521A to 554.3A range) while maintaining functional equivalence for general-purpose transient voltage suppression. Packaging format differences (Tape & Reel versus Cut Tape) and supplier device package variations (P600 versus R-6) do not affect electrical performance but influence procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

5KP5.0CA (Littelfuse Inc.): This substitute maintains identical electrical specifications for reverse standoff voltage (5V), breakdown voltage (6.4V), and peak pulse power (5000W). The clamping voltage is 9.2V compared to 9.6V on the original part, representing a 0.4V reduction within acceptable tolerance for general-purpose transient suppression. Peak pulse current is rated at 554.3A, exceeding the original 521A specification. Both parts are ROHS3 compliant with MSL 1 rating and Active product status. The primary difference is packaging format (Cut Tape versus Tape & Reel) and supplier device package (P600 axial). This substitute is suitable for applications where Cut Tape packaging is acceptable.

5KP5.0CA-TP (Micro Commercial Co): This substitute maintains identical reverse standoff voltage (5V), breakdown voltage (6.4V), and peak pulse power (5000W) specifications. The clamping voltage is 9.2V, consistent with the Littelfuse alternative. Peak pulse current is not specified in available documentation. The supplier device package is R-6 axial rather than P600 axial, which may require verification of mechanical fit in existing through-hole PCB layouts. Both parts are ROHS3 compliant with MSL 1 rating and Active product status. This substitute is suitable where R-6 package compatibility is confirmed and Cut Tape packaging is acceptable.

All three parts share identical operating temperature range (-55°C to 175°C), compliance certifications (ROHS3, REACH Unaffected), and general-purpose application classification. Selection between alternatives depends on packaging availability, supplier device package compatibility with PCB design, and clamping voltage tolerance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5KP5.0CA substitute directly for the 5KP5.0CE3/TR13 in the same circuit?

A: Yes, the 5KP5.0CA is electrically equivalent for general-purpose transient voltage suppression. Both parts maintain 5V reverse standoff voltage, 6.4V minimum breakdown voltage, and 5000W peak pulse power. The 9.2V clamping voltage on the 5KP5.0CA is 0.4V lower than the 9.6V specification of the original part, which is within acceptable tolerance for most applications. The primary difference is packaging format (Cut Tape versus Tape & Reel).

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

A: Both P600 and R-6 are axial through-hole package designations for TVS diodes. The package type affects the physical dimensions and lead spacing. Substitution between P600 and R-6 requires confirmation that the PCB layout and through-hole spacing accommodate the alternative package dimensions. Consult the respective component datasheets for precise mechanical specifications.

Q: Does the higher peak pulse current rating of the 5KP5.0CA (554.3A versus 521A) affect compatibility?

A: No. A higher peak pulse current rating indicates greater surge handling capability and does not create compatibility issues. The 5KP5.0CA can handle transient events that the original part can handle, plus additional margin. This represents an improvement in performance headroom.

Q: Are all three parts suitable for the same operating temperature range?

A: Yes. All three parts operate across the identical temperature range of -55°C to 175°C (TJ). Temperature performance is equivalent across all substitutes.

Q: What is the significance of the clamping voltage difference between 9.6V and 9.2V?

A: The clamping voltage determines the maximum voltage that appears across the TVS diode during a transient event. The 0.4V difference between 9.6V and 9.2V is typically negligible for general-purpose protection circuits. However, applications with strict voltage regulation requirements should verify that the lower clamping voltage of the substitute parts remains within acceptable limits for downstream components.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three parts (5KP5.0CE3/TR13, 5KP5.0CA, and 5KP5.0CA-TP) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level and REACH Unaffected status. Compliance certifications are identical across all options.

Q: What does "Tape & Reel" versus "Cut Tape" packaging mean for procurement?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape packaging supplies components on shorter tape segments, typically used for lower-volume orders or manual assembly. The electrical performance is identical; packaging format affects only procurement quantity minimums and assembly workflow.

Q: Can the 5KP5.0CA-TP be used if peak pulse current is not specified?

A: The 5KP5.0CA-TP maintains all critical electrical parameters: 5V reverse standoff voltage, 6.4V breakdown voltage, 9.2V clamping voltage, and 5000W peak pulse power. The unspecified peak pulse current does not prevent functional substitution for general-purpose applications. However, applications requiring specific peak pulse current verification should reference the manufacturer's complete datasheet or contact the supplier for this specification.
