• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 150mA
• Number of Elements: 6
• Capacitance: 25pF, 35pF
• Package / Case: 6-SMD, Gull Wing
• Mounting Type: Surface Mount

The P3206UCLTP meets all specified electrical and mechanical requirements and is classified as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The P3206UCLTP is the direct functional equivalent of the P3206UCTP. Both parts share identical electrical specifications and mechanical packaging. The primary distinction is product status: the P3206UCTP is obsolete while the P3206UCLTP is active and currently in production.

For new designs and ongoing system support, the P3206UCLTP is the appropriate selection. This part offers the additional advantage of ROHS3 compliance, whereas the original P3206UCTP is non-compliant. The P3206UCLTP is supplied in tube packaging and maintains full compatibility with existing PCB layouts and assembly processes designed for the P3206UCTP.

Frequently Asked Questions (FAQ)

Q: Can the P3206UCLTP be used as a direct replacement for the P3206UCTP?

A: Yes. The P3206UCLTP is electrically and mechanically identical to the P3206UCTP across all specified parameters, including voltage ratings, current handling, element count, capacitance values, and 6-SMD gull wing package configuration.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and regulatory compliance. The P3206UCTP is obsolete, while the P3206UCLTP is active. The P3206UCLTP is ROHS3 compliant, whereas the P3206UCTP is non-compliant. Packaging differs: P3206UCLTP is supplied in tube format.

Q: Are there any compatibility concerns when substituting the P3206UCLTP for the P3206UCTP?

A: No compatibility concerns exist. The parts are pin-compatible, functionally equivalent, and suitable for direct PCB substitution without design modifications.

Q: What is the availability status of these parts?

A: The P3206UCTP is obsolete with limited inventory. The P3206UCLTP is active and in current production, ensuring long-term availability for procurement and supply chain planning.
