Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P3203UATP is determined by strict equivalence across the following critical parameters:

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

The P3203UALTP meets all electrical and mechanical requirements for direct substitution. Both parts share identical voltage ratings, current handling capabilities, element count, and capacitance specifications. Both are housed in the 6-SMD gull wing package with Modified MS-013 supplier device packaging, ensuring mechanical and electrical compatibility in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The P3203UALTP is the direct substitute for the obsolete P3203UATP. Both components are electrically and mechanically identical across all specified parameters.

The P3203UALTP carries an Active product status, ensuring ongoing availability and manufacturer support. The P3203UALTP is ROHS3 compliant and REACH unaffected, providing regulatory compliance advantages over the non-compliant P3203UATP. Both parts share identical electrical performance characteristics and package specifications, enabling direct replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can the P3203UALTP replace the P3203UATP in existing designs?

A: Yes. The P3203UALTP is electrically and mechanically equivalent to the P3203UATP. All voltage ratings, current specifications, element count, capacitance values, and package configurations are identical. Direct substitution is supported without circuit redesign.

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

A: The primary differences are product status and regulatory compliance. The P3203UATP is obsolete and RoHS non-compliant. The P3203UALTP is active, ROHS3 compliant, and REACH unaffected. Packaging differs: P3203UATP uses standard packaging while P3203UALTP is supplied in tube packaging.

Q: Are there any electrical performance differences?

A: No. Both parts share identical electrical specifications: 270V off-state voltage, 350V breakover voltage, 8V on-state voltage, 150A peak pulse current (8/20µs), 45A peak pulse current (10/1000µs), 150mA hold current, and 45pF/70pF capacitance values.

Q: Is the 6-SMD gull wing package compatible with existing PCB layouts?

A: Yes. Both parts use the identical 6-SMD gull wing package with Modified MS-013 supplier device packaging. PCB footprints, solder pad configurations, and mounting requirements are unchanged.

Q: What is the moisture sensitivity level for these components?

A: Both the P3203UATP and P3203UALTP have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
