5KP26A-TP Equivalent & Substitute Parts

Part Overview

The 5KP26A-TP is a unidirectional transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This through-hole component operates across a wide temperature range (-55°C to 175°C) and is RoHS3 compliant. The part is currently active in production with 1143 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP26A-TP is determined by matching the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 26V
• Voltage - Breakdown (Min): 28.9V
• Voltage - Clamping (Max) @ Ipp: 42.1V
• Power - Peak Pulse: 5000W
• Unidirectional Channels: 1
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 175°C
• RoHS3 Compliance

The 5KP26A manufactured by Littelfuse Inc. meets all these criteria and qualifies as a direct electrical equivalent. Both parts belong to the 5KP series TVS diode family and share identical voltage specifications and power ratings. The primary difference is the package designation (R-6 versus P600 axial package), which represents different supplier packaging formats for the same component class.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP26A-TP and 5KP26A are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

1. Package availability: The 5KP26A-TP uses R-6 axial packaging, while the 5KP26A uses P600 axial packaging. Verify PCB footprint compatibility with your design.

2. Supplier inventory: The 5KP26A (Littelfuse) currently has 4605 units in stock compared to 1143 units for the 5KP26A-TP (Micro Commercial Co), which may influence lead time and procurement strategy.

3. Electrical equivalence: Both parts deliver identical voltage protection characteristics (26V standoff, 42.1V clamping) and 5000W peak pulse power rating, making them functionally interchangeable for general-purpose transient suppression applications.

4. Regulatory compliance: Both parts meet identical environmental and regulatory requirements (RoHS3, REACH, MSL 1), ensuring no compliance risk in substitution.

Frequently Asked Questions (FAQ)

Q: Can the 5KP26A replace the 5KP26A-TP in my circuit?

A: Yes. Both parts are electrically equivalent with identical voltage specifications (26V standoff, 28.9V breakdown minimum, 42.1V clamping maximum) and power rating (5000W peak pulse). The primary consideration is package compatibility—verify that your PCB footprint accommodates either the R-6 or P600 axial package format.

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

A: Both are axial through-hole packages for TVS diodes. R-6 and P600 represent different supplier packaging designations. Physical dimensions and lead spacing may differ; confirm compatibility with your PCB layout before substitution.

Q: Are there any compliance differences between these parts?

A: No. Both the 5KP26A-TP and 5KP26A carry identical certifications: RoHS3 compliant, REACH unaffected, and MSL 1 (unlimited moisture sensitivity level). They present no regulatory or environmental compliance risk when substituted.

Q: What voltage range does the 5KP26A-TP protect?

A: The part maintains a 26V reverse standoff voltage and clamps transient overvoltages to a maximum of 42.1V at peak pulse current. It is suitable for protecting circuits designed to operate at or below 26V nominal.

Q: Can I use the 5KP26A-TP for power line protection applications?

A: No. The product specifications indicate this component is not rated for power line protection. It is designated for general-purpose transient suppression only.

Q: What is the operating temperature range for these TVS diodes?

A: Both parts operate across -55°C to 175°C junction temperature (TJ), providing performance across industrial and extended temperature environments.
