Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2356UATP is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part P2356UALTP qualifies as a direct equivalent because it maintains identical specifications across the following key criteria:

• Voltage ratings: breakover (270V), off-state (200V), and on-state (8V)
• Current performance: peak pulse ratings at both 8/20µs (150A) and 10/1000µs (45A) intervals
• Hold current (150 mA)
• Element count (6 elements)
• Capacitance range (25pF, 35pF)
• Physical form factor: 6-SMD gull wing surface mount package
• Supplier device package designation (Modified MS-013)

The substitute differs only in packaging format (tube versus unspecified for the main part) and product status (active versus obsolete), with improved RoHS and REACH compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The P2356UALTP is the direct substitute for the obsolete P2356UATP. Selection of the substitute part is justified on the following grounds:

• Complete electrical parameter equivalence across all voltage and current specifications
• Identical mechanical and thermal characteristics, including package form factor and MSL rating
• Active product status ensures ongoing availability and manufacturer support
• ROHS3 compliance and REACH unaffected status provide regulatory alignment for new designs and procurement cycles
• Tube packaging format is standard for production environments and does not affect electrical or thermal performance

No additional design modifications, PCB layout changes, or thermal management adjustments are required when transitioning from the main part to the substitute.

Frequently Asked Questions (FAQ)

Q: Can P2356UALTP be used as a direct replacement for P2356UATP in existing designs?

A: Yes. All electrical parameters, mechanical dimensions, and thermal characteristics are identical. The substitute requires no design changes or PCB modifications.

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

A: The primary difference is product status: P2356UATP is obsolete, while P2356UALTP is active. The substitute also includes ROHS3 compliance certification. Electrical and mechanical specifications are identical.

Q: Does the tube packaging of P2356UALTP affect performance compared to the main part?

A: No. Packaging format does not affect electrical performance, thermal characteristics, or reliability. Tube packaging is standard for production assembly processes.

Q: Are there any compliance or certification differences?

A: P2356UALTP carries ROHS3 compliance and REACH unaffected status, whereas P2356UATP is RoHS non-compliant. This makes the substitute suitable for applications with regulatory compliance requirements.

Q: What is the inventory status of the substitute part?

A: P2356UALTP has 1072 pieces in stock as new original inventory, ensuring procurement availability.
