Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP7.5C is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 7.5V
• Bidirectional Channels: 1
• Power - Peak Pulse: 5000W (5kW)
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature Range: -55°C ~ 175°C (TJ)

Allowable Variation Parameters:

• Voltage - Breakdown (Min): Range 7.89V to 8.33V
• Voltage - Clamping (Max) @ Ipp: Range 12.9V to 14.3V
• Current - Peak Pulse (10/1000µs): Varies by design

The identified substitute parts maintain identical standoff voltage, power rating, package configuration, and thermal operating range. Variations in breakdown voltage and clamping voltage remain within acceptable engineering tolerances for general-purpose transient protection applications.

Parameter Comparison

Engineering Selection Recommendations

5KP7.5CA (Littelfuse Inc.): This part is the direct Littelfuse equivalent, maintaining manufacturer continuity while offering active product status. It provides lower clamping voltage (12.9V) compared to the obsolete 5KP7.5C (14.65V), resulting in improved transient suppression performance. This part is available in Cut Tape packaging and carries full ROHS3 compliance.

5KP7.5CE3/TR13 (Microchip Technology): This part represents a cross-manufacturer substitute from Microchip Technology, also maintaining active product status. It exhibits higher clamping voltage (14.3V) and lower peak pulse current (350A) relative to the 5KP7.5CA. This part is supplied in Tape & Reel format and carries full ROHS3 and REACH compliance certifications.

Both substitute parts satisfy the electrical and mechanical requirements for direct replacement in applications originally designed for the 5KP7.5C, with selection dependent on packaging requirements and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can the 5KP7.5CA and 5KP7.5CE3/TR13 be used interchangeably with the 5KP7.5C?

A: Both parts maintain identical reverse standoff voltage (7.5V), power rating (5000W), operating temperature range (-55°C to 175°C), and P600 axial through-hole package configuration. Clamping voltage variations (12.9V to 14.3V) remain within acceptable tolerances for general-purpose transient protection. Direct substitution is supported from an electrical and mechanical standpoint.

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

A: Cut Tape (CT) packaging supplies individual components on tape segments suitable for manual handling and smaller production volumes. Tape & Reel (TR) packaging provides continuous reel format optimized for automated assembly equipment and higher-volume manufacturing. Both formats contain identical components; selection depends on assembly process requirements.

Q: Why does the 5KP7.5CA have lower clamping voltage than the original 5KP7.5C?

A: Clamping voltage variation within the specified range (12.9V to 14.3V) reflects normal manufacturing tolerance and design optimization across different production batches and manufacturers. The 5KP7.5CA's lower clamping voltage (12.9V) provides enhanced transient suppression performance while maintaining all critical electrical parameters.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 5KP7.5CA and 5KP7.5CE3/TR13 carry ROHS3 compliance certification, meeting environmental and regulatory requirements equivalent to the original 5KP7.5C.

Q: What is the significance of the 5KP7.5CE3/TR13 having REACH compliance?

A: REACH compliance indicates the part meets European chemical safety regulations. This certification is relevant for applications subject to European regulatory requirements or supply chains requiring enhanced environmental documentation.
