P2353UBTP Equivalent & Substitute Parts

Part Overview

The P2353UBTP is a SIDACtor® Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., designed for overvoltage protection in surface mount applications. This device features a 200V off-state voltage rating with 250A peak pulse current capability in an industry-standard 6-SMD gull wing package. The P2353UBTP is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2353UBTP is determined by electrical and mechanical parameter equivalence. The critical parameters defining substitutability are:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current specifications (8/20µs and 10/1000µs waveforms)
• Hold current (Ih)
• Number of elements (3-element configuration)
• Capacitance values
• Physical package format (6-SMD, gull wing)
• Mounting type (surface mount)

The P2353UBLTP meets all these criteria as a direct electrical and mechanical equivalent, with identical voltage and current ratings, element count, and package specifications.

Parameter Comparison

Engineering Selection Recommendations

The P2353UBLTP is the direct substitute for the obsolete P2353UBTP. Both parts are electrically and mechanically identical across all specified parameters. The primary distinction is product status and regulatory compliance:

The P2353UBTP is obsolete and RoHS non-compliant. The P2353UBLTP is active in production and ROHS3 compliant, making it the appropriate choice for new designs and ongoing system support. The P2353UBLTP is supplied in tube packaging, whereas the original part number does not specify packaging format.

For applications requiring the 200V/250A TVS thyristor specification in 6-SMD gull wing configuration, the P2353UBLTP provides full functional and physical compatibility with the added benefit of current production availability and enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the P2353UBLTP be used as a direct replacement for the P2353UBTP?
