P2353UATP Equivalent & Substitute Parts

Part Overview

The P2353UATP is a 200V off-state, 150A peak pulse TVS thyristor manufactured by Littelfuse in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring high current handling in a compact 6-SMD gull wing package. The part is currently obsolete, making identification of active equivalent parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2353UATP is determined by matching the following critical electrical and mechanical parameters:

• Voltage ratings (breakover, off-state, and on-state)
• Current specifications (peak pulse at 8/20µs and 10/1000µs, hold current)
• Number of internal elements
• Capacitance values
• Package type and mounting configuration

The P2353UALTP meets all these criteria with identical electrical specifications and the same 6-SMD gull wing package. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The P2353UALTP is the direct functional equivalent of the P2353UATP. Both parts share identical electrical characteristics and mechanical specifications. Selection between these parts is determined by:

• Product availability: P2353UALTP is active and currently available, while P2353UATP is obsolete
• Regulatory compliance: P2353UALTP meets ROHS3 compliance requirements, whereas P2353UATP is non-compliant
• Packaging: P2353UALTP is supplied in tube packaging, providing standard handling and storage conditions

For new designs or ongoing procurement, P2353UALTP is the appropriate selection. For legacy systems requiring the original part number, P2353UALTP provides electrical and mechanical compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can P2353UALTP replace P2353UATP in existing applications?

A: Yes. Both parts have identical voltage ratings, current specifications, element count, and capacitance values. The 6-SMD gull wing package and surface mount configuration are identical, allowing direct substitution without PCB redesign.

Q: What is the difference between these parts?

A: The primary differences are product status, RoHS compliance, and packaging format. P2353UALTP is an active part with ROHS3 compliance supplied in tube packaging, while P2353UATP is obsolete and non-compliant.

Q: Are there any electrical performance differences?

A: No. Both parts operate at 270V breakover, 200V off-state, and 8V on-state. Peak pulse current (150A at 8/20µs), hold current (150mA), and capacitance values are identical.

Q: Is the package footprint identical?

A: Yes. Both parts use the 6-SMD gull wing package with the same mechanical dimensions and pin configuration. No layout modifications are required for substitution.

Q: Why is P2353UATP listed as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation. P2353UALTP represents the current active equivalent in the SIDACtor® product line.
