Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6KE8.2A-TP are classified based on electrical and mechanical compatibility within the transient voltage suppressor category. Substitution eligibility is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 7.0V to 7.02V range
• Voltage - Clamping (Max) @ Ipp: 12.0V to 12.1V range
• Unidirectional Channels: 1 channel configuration
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 175°C minimum
• RoHS3 Compliance: Required
• Package compatibility: DO-15, DO-201, or equivalent axial through-hole packages

Two substitute parts meet these criteria: the P6KE8.2A (direct equivalent from Taiwan Semiconductor Corporation) and the LCE7.0A (similar specification from Littelfuse Inc.).

Parameter Comparison

Engineering Selection Recommendations

P6KE8.2A (Direct Equivalent)

The P6KE8.2A from Taiwan Semiconductor Corporation is a direct electrical equivalent to the P6KE8.2A-TP. Both parts share identical voltage specifications (7.02V reverse standoff, 12.1V clamping), matching temperature range (-55°C to 175°C), and equivalent power dissipation (600W). The P6KE8.2A maintains RoHS3 compliance and MSL 1 rating. Peak pulse current is marginally higher at 52A versus 50A, representing a 4% increase in current handling capacity. Package compatibility is confirmed for DO-15/DO-204AC through-hole applications. This part is suitable for direct substitution in existing designs.

LCE7.0A (Similar Specification)

The LCE7.0A from Littelfuse Inc. operates within the acceptable voltage range (7V reverse standoff, 12V clamping) and maintains identical temperature specifications and compliance certifications. This part differs in two key aspects: package format (DO-201 versus DO-15) and current/power ratings (100A peak pulse, 1500W versus 50A, 600W). The LCE7.0A is suitable for applications requiring higher transient current handling or where DO-201 package compatibility exists in the circuit design. Package physical dimensions differ between DO-15 and DO-201 formats; board layout verification is necessary before selection.

All substitute parts maintain active production status, RoHS3 compliance, and unlimited moisture sensitivity rating, supporting long-term supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the P6KE8.2A be used as a direct replacement for the P6KE8.2A-TP?

A: Yes. Both parts are electrically identical with matching voltage specifications (7.02V reverse standoff, 12.1V clamping), current ratings (50A/52A peak pulse), power dissipation (600W), and operating temperature range (-55°C to 175°C). Both are RoHS3 compliant and packaged in DO-15/DO-204AC through-hole format. The P6KE8.2A is a direct equivalent.

Q: What are the key differences between the P6KE8.2A-TP and the LCE7.0A?

A: The primary differences are package format and current/power handling. The LCE7.0A uses DO-201 package versus DO-15 for the P6KE8.2A-TP, and provides higher peak pulse current (100A versus 50A) and power dissipation (1500W versus 600W). Voltage specifications are within acceptable tolerance (7V versus 7.02V reverse standoff; 12V versus 12.1V clamping). Physical package dimensions differ; board layout compatibility must be confirmed.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The P6KE8.2A and LCE7.0A are both RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, matching the compliance profile of the P6KE8.2A-TP.

Q: Can the LCE7.0A be used in a DO-15 package footprint?

A: No. The LCE7.0A is packaged in DO-201 format, which has different physical dimensions than DO-15. While both are axial through-hole packages, they are not mechanically interchangeable on a PCB designed for DO-15 components. Package compatibility must be verified before selection.

Q: Which substitute part should be selected for higher transient current protection?

A: The LCE7.0A provides higher peak pulse current (100A) and power dissipation (1500W) compared to the P6KE8.2A-TP (50A, 600W). Selection depends on circuit transient requirements and package compatibility with the existing board design.

Q: Do all parts operate across the same temperature range?

A: Yes. The P6KE8.2A-TP, P6KE8.2A, and LCE7.0A all operate from -55°C to 175°C junction temperature, supporting identical thermal specifications for general-purpose applications.
