Key Parameters

Substitute Part Grouping Explanation

Substitution of the P3203UCTP is determined by matching the following critical electrical and mechanical parameters:

• Voltage ratings (off-state, breakover, and on-state)
• Peak pulse current specifications (both 8/20µs and 10/1000µs ratings)
• Hold current (Ih) requirement
• Number of internal elements
• Capacitance values
• Package type and mounting configuration

The P3203UCLTP qualifies as a direct substitute based on identical electrical specifications across all voltage and current parameters, matching element count, capacitance values, and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The P3203UCLTP is the direct equivalent for the obsolete P3203UCTP. Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in all applications where the original part was specified.

The P3203UCLTP offers the additional advantage of active product status, indicating ongoing manufacturer support and availability. The P3203UCLTP is ROHS3 compliant and REACH unaffected, providing enhanced regulatory compliance compared to the non-compliant status of the original part. Both components maintain MSL 1 (unlimited) moisture sensitivity rating.

Selection between these parts should be based on procurement requirements and regulatory compliance mandates for the end application.

Frequently Asked Questions (FAQ)

Q: Can P3203UCLTP replace P3203UCTP in existing designs? A: Yes. The P3203UCLTP is electrically and mechanically identical to the P3203UCTP across all specified parameters, including voltage ratings, current handling, element count, capacitance, and package configuration.

Q: What is the difference between P3203UCTP and P3203UCLTP? A: The primary differences are product status and packaging. The P3203UCTP is obsolete with non-compliant RoHS status, while the P3203UCLTP is active, ROHS3 compliant, and supplied in tube packaging. All electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with the 6-SMD gull wing package? A: No. Both parts use the identical 6-SMD gull wing package configuration with modified MS-013 supplier device package designation, ensuring direct PCB compatibility without layout modifications.

Q: Does the P3203UCLTP meet current regulatory requirements? A: The P3203UCLTP is ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The original P3203UCTP does not meet these compliance requirements.

Q: What inventory status should be considered for procurement? A: The P3203UCTP has 848 pieces in stock but is obsolete. The P3203UCLTP has 863 pieces in stock and maintains active product status, making it the preferred choice for new procurement and long-term availability.
