Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P4KE7.5A-TP is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 6.4V
• Voltage - Clamping (Max) @ Ipp: 11.3V
• Current - Peak Pulse (10/1000µs): 36.3A minimum
• Operating Temperature Range: -55°C ~ 175°C
• Mounting Type: Through Hole
• Package / Case: DO-204AL or DO-41 equivalent
• Type: Zener unidirectional TVS diode

The P4KE7.5A manufactured by Taiwan Semiconductor Corporation meets all substitution criteria with matching electrical specifications and compatible packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the P4KE7.5A-TP and P4KE7.5A are active production components with identical regulatory compliance status. The P4KE7.5A from Taiwan Semiconductor Corporation provides a functionally equivalent alternative with a marginally higher peak pulse current specification (37A versus 36.3A), which does not reduce compatibility. Both parts maintain RoHS3 compliance and REACH unaffected status, making either suitable for applications requiring environmental and regulatory adherence. Selection between these parts may be based on availability, lead time, or procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the P4KE7.5A substitute for the P4KE7.5A-TP in all applications?

A: Yes. Both parts share identical voltage specifications (6.4V reverse standoff, 11.3V clamping), matching operating temperature ranges, and compatible through-hole packaging. The P4KE7.5A meets or exceeds the current rating of the original part.

Q: Are there package differences between these parts?

A: Both parts use DO-204AL and DO-41 axial through-hole packages. The supplier device package designation differs slightly (DO-41 for the original, DO-204AL (DO-41) for the substitute), but these refer to the same physical package format suitable for identical PCB layouts.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the P4KE7.5A-TP and P4KE7.5A are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the difference in peak pulse current between these parts?

A: The P4KE7.5A-TP is rated for 36.3A peak pulse current, while the P4KE7.5A is rated for 37A. This 0.7A difference does not affect substitution eligibility and represents a marginal improvement in the substitute part.

Q: Are there any temperature range limitations?

A: No. Both parts operate across the identical temperature range of -55°C to 175°C (junction temperature), ensuring compatibility across all specified operating conditions.
