Key Parameters

Substitute Part Grouping Explanation

Substitution for the P2353UCTP is determined by electrical and mechanical parameter equivalence. The substitute part P2353UCLTP maintains identical electrical specifications across all critical parameters: off-state voltage (200V), breakover voltage (270V), on-state voltage (8V), peak pulse currents (400A at 8/20µs and 100A at 10/1000µs), hold current (150mA), element count (3), and capacitance values (50pF, 75pF). Both parts share the same package configuration (6-SMD, Gull Wing) and mounting type (Surface Mount), ensuring mechanical and thermal compatibility. The primary distinction is product status and packaging format, with P2353UCLTP being an active product supplied in tube packaging.

Parameter Comparison

Engineering Selection Recommendations

P2353UCLTP is the direct substitute for P2353UCTP. Both parts are electrically and mechanically identical across all specified parameters. The substitute part offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, P2353UCLTP meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant. For new designs or system replacements, P2353UCLTP is the appropriate selection. The tube packaging of the substitute part is standard for production environments and does not affect functional performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can P2353UCLTP be used as a direct replacement for P2353UCTP in existing designs? A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters, including voltage ratings, current handling, element count, capacitance, and package configuration. No circuit modifications are required.

Q: What is the difference between P2353UCTP and P2353UCLTP? A: The parts are functionally identical. The primary differences are product status (obsolete vs. active), packaging format (unspecified vs. tube), and RoHS compliance (non-compliant vs. ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Is the 6-SMD, Gull Wing package compatible with standard PCB assembly processes? A: Yes. Both parts use the same 6-SMD, Gull Wing surface mount package with Modified MS-013 supplier device package designation, compatible with standard reflow soldering and automated assembly equipment.

Q: Does the RoHS3 compliance of P2353UCLTP affect performance compared to the non-compliant P2353UCTP? A: No. RoHS compliance relates to material composition and environmental standards, not electrical or thermal performance. Both parts maintain identical functional specifications.

Q: Are there any moisture sensitivity considerations for these parts? A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control measures. Standard handling and storage practices are sufficient.
