Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP7.5A-B is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Reverse standoff voltage of 7.5V, breakdown voltage minimum of 8.33V, and clamping voltage maximum of 12.9V
• Current Handling: Peak pulse current of 395.3A at 10/1000µs pulse duration
• Power Dissipation: Peak pulse power rating of 5000W (5kW)
• Mechanical Compatibility: Through-hole mounting with P600 axial package configuration
• Channel Configuration: Single unidirectional channel (Zener type)
• Regulatory Compliance: RoHS3 and REACH compliance status

The substitute part 5KP7.5A matches all electrical and mechanical parameters with the main part. The only difference is packaging format (Cut Tape versus Bulk), which does not affect functional performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP7.5A-B and 5KP7.5A are active production components from Littelfuse Inc. with identical electrical specifications and mechanical form factors. Selection between these parts should be based on packaging requirements and supply chain considerations:

• 5KP7.5A-B (Bulk packaging): Suitable for high-volume manufacturing environments with internal tape-and-reel conversion capabilities or direct bulk component handling systems.
• 5KP7.5A (Cut Tape packaging): Appropriate for automated pick-and-place assembly lines and standard manufacturing workflows that utilize standard tape-and-reel component feeders.

Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across all target markets. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for storage or handling.

Frequently Asked Questions (FAQ)

Q: Can 5KP7.5A be used as a direct replacement for 5KP7.5A-B?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Bulk). Direct substitution is valid for circuit applications.

Q: What determines if a TVS diode can substitute for the 5KP7.5A-B?

A: Substitution requires matching specifications across voltage ratings (7.5V standoff, 8.33V breakdown minimum, 12.9V clamping maximum), current handling (395.3A peak pulse), power dissipation (5000W), mounting type (through-hole), and package configuration (P600 axial).

Q: Does packaging format affect electrical performance?

A: No. Bulk and Cut Tape packaging formats contain identical components. Packaging differences only impact supply chain logistics and assembly line compatibility.

Q: Are there any compliance differences between the substitute parts?

A: No. Both 5KP7.5A-B and 5KP7.5A maintain identical RoHS3 and REACH compliance status with MSL rating of 1 (Unlimited).

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

A: Both parts operate across -55°C to 175°C junction temperature range, suitable for industrial and commercial applications.
