Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP7.5E3/TR13 is determined by strict electrical and mechanical parameter matching within the TVS diode category. The following parameters establish substitution eligibility:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 7.5V
• Voltage - Breakdown (Min): 8.33V
• Package / Case: P600, Axial
• Mounting Type: Through Hole
• Type: Zener, Unidirectional
• Unidirectional Channels: 1
• Operating Temperature Range: -55°C to 175°C (TJ)
• Power - Peak Pulse: 5000W (5kW)
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: Acceptable within device specification limits
• Current - Peak Pulse (10/1000µs): Acceptable within device specification limits
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) formats are interchangeable for the same component

The 5KP7.5A manufactured by Littelfuse Inc. meets all critical matching parameters and qualifies as a direct electrical and mechanical substitute.

Parameter Comparison

Engineering Selection Recommendations

The 5KP7.5A (Littelfuse Inc.) is a qualified substitute for the 5KP7.5E3/TR13 (Microchip Technology) based on the following engineering criteria:

Electrical Compatibility: Both devices maintain identical reverse standoff voltage (7.5V), breakdown voltage minimum (8.33V), and peak pulse power rating (5000W). The 5KP7.5A exhibits a lower clamping voltage (12.9V versus 14.3V) and higher peak pulse current capability (395.3A versus 350A), both of which represent improved performance characteristics within the TVS diode specification envelope.

Mechanical Compatibility: Both parts utilize the P600 axial through-hole package, ensuring direct mechanical interchangeability on printed circuit boards without requiring layout modifications or mechanical redesign.

Regulatory Compliance: Both devices maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status, satisfying identical regulatory and environmental requirements.

Product Status: Both parts are active in production with confirmed inventory availability, ensuring supply chain continuity.

Selection between these parts should be based on availability, lead time, cost considerations, and specific application requirements for clamping voltage performance.

Frequently Asked Questions (FAQ)

Q: Can the 5KP7.5A directly replace the 5KP7.5E3/TR13 in existing circuit designs?

A: Yes. Both devices share identical reverse standoff voltage, breakdown voltage, operating temperature range, package type, and mounting configuration. The 5KP7.5A provides equivalent electrical protection with improved peak pulse current capability and lower clamping voltage performance.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for automated assembly processes. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for manual assembly or smaller production runs. Both formats contain identical components and are mechanically interchangeable on circuit boards.

Q: Are there any performance differences between the Microchip and Littelfuse versions?

A: The 5KP7.5A (Littelfuse) exhibits a clamping voltage of 12.9V compared to 14.3V for the 5KP7.5E3/TR13 (Microchip), and provides higher peak pulse current capability (395.3A versus 350A). These differences represent improved transient suppression performance within the device specification limits and do not affect functional compatibility.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the 5KP7.5E3/TR13 and 5KP7.5A are ROHS3 compliant, carry MSL Level 1 (Unlimited) moisture sensitivity rating, and are REACH Unaffected, satisfying identical regulatory requirements.

Q: What parameters must remain constant when selecting a substitute TVS diode?

A: Critical parameters that must match are reverse standoff voltage (7.5V), breakdown voltage minimum (8.33V), package type (P600 axial), mounting configuration (through hole), device type (zener unidirectional), operating temperature range (-55°C to 175°C), and power rating (5000W). Peak pulse current and clamping voltage may vary within device specification limits.
