5KP7.5A-TP Equivalent & Substitute Parts

Part Overview

The 5KP7.5A-TP is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient voltage protection applications. This axial through-hole component features a 7.5V reverse standoff voltage with a 12.9V maximum clamping voltage and 5000W peak pulse power rating. The part is Active in product status and ROHS3 compliant, making it suitable for modern electronic circuit protection requirements. Equivalent and substitute parts are identified when they maintain identical or functionally compatible electrical and mechanical parameters within the constraints of this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP7.5A-TP are identified based on the following critical parameters that determine functional compatibility:

• Voltage Rating Match: Reverse standoff voltage of 7.5V, breakdown voltage minimum of 8.33V, and clamping voltage maximum of 12.9V must be maintained
• Unidirectional Configuration: Single channel Zener TVS diode topology
• Power Dissipation: Peak pulse power rating of 5000W (5kW)
• Temperature Range: Operating junction temperature range of -55°C to 175°C
• Mounting and Package: Through-hole axial configuration for PCB integration
• Compliance: ROHS3 compliance and Active product status

Substitutes are grouped by their ability to meet these electrical specifications while accommodating variations in package designations (R-6, P600, DO-201) and manufacturer implementations.

Parameter Comparison

Engineering Selection Recommendations

5KP7.5A (Littelfuse Inc.) is a direct electrical equivalent to the 5KP7.5A-TP. Both parts maintain identical voltage ratings (7.5V reverse standoff, 8.33V breakdown minimum, 12.9V clamping maximum), identical power dissipation (5000W peak pulse), and identical operating temperature range (-55°C to 175°C). Both are Active products with ROHS3 compliance. The primary difference is the package designation (P600 versus R-6), which represents a variation in physical form factor but maintains through-hole axial mounting compatibility. This substitute is suitable for direct replacement in applications where the P600 package footprint is acceptable.

LCE7.5A (Littelfuse) maintains identical voltage ratings and operating temperature range as the main part. However, the peak pulse power rating is 1500W (1.5kW), which is lower than the 5000W specification of the 5KP7.5A-TP. This part is suitable only for applications with reduced transient energy requirements. The DO-201 package provides through-hole axial mounting compatibility. Both parts are Active with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the 5KP7.5A from Littelfuse directly replace the 5KP7.5A-TP from Micro Commercial Co?

A: Yes. Both parts share identical electrical specifications: 7.5V reverse standoff voltage, 8.33V minimum breakdown voltage, 12.9V maximum clamping voltage, and 5000W peak pulse power rating. The voltage and power parameters are the primary determinants of TVS diode functionality. Package designation differences (R-6 versus P600) do not affect electrical performance, though PCB footprint compatibility must be verified for your specific application.

Q: When is the LCE7.5A an appropriate substitute?

A: The LCE7.5A is appropriate only when your application requires lower transient energy dissipation. This part is rated for 1500W peak pulse power compared to the 5000W rating of the main part. If your circuit experiences transient events exceeding 1500W, the LCE7.5A will not provide adequate protection. Voltage ratings remain identical across all three parts.

Q: Are package differences between R-6, P600, and DO-201 significant for substitution?

A: Package differences affect PCB layout and footprint compatibility but do not impact electrical performance. All three packages are through-hole axial configurations suitable for traditional PCB mounting. Verify that your PCB design accommodates the specific package dimensions before substitution. Consult component datasheets for precise lead spacing and body dimensions.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. The 5KP7.5A-TP, 5KP7.5A, and LCE7.5A are all ROHS3 compliant and REACH unaffected. All parts are classified as Active products. Compliance certifications are identical across all three parts.

Q: What is the primary criterion for TVS diode substitution in this category?

A: Voltage rating compatibility is the primary criterion. The reverse standoff voltage, breakdown voltage, and clamping voltage must match the original specification. Secondary criteria include power dissipation capability and operating temperature range. Package and manufacturer differences are acceptable provided electrical specifications align with circuit protection requirements.
