P2356UBRP Equivalent & Substitute Parts

Part Overview

The P2356UBRP is a 200V off-state, 250A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring high current handling in a compact 6-SMD gull wing surface mount package. The part is currently obsolete, making identification of compatible substitutes essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P2356UBRP 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 waveforms)
• Hold current (Ih)
• Number of internal elements
• Capacitance range
• Physical package and mounting configuration

The P2356UBLRP qualifies as a direct substitute based on identical electrical specifications and package geometry. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P2356UBLRP is the direct functional equivalent of the P2356UBRP. Both components share identical electrical characteristics and physical package specifications, ensuring pin-for-pin and functional compatibility.

Selection between these parts should be based on:

• Product status: P2356UBLRP is active and currently manufactured, while P2356UBRP is obsolete
• Regulatory compliance: P2356UBLRP meets ROHS3 compliance requirements, whereas P2356UBRP is non-compliant
• Packaging requirements: P2356UBLRP is supplied in tape and reel format, suitable for automated assembly; P2356UBRP was supplied in bulk packaging
• Supply availability: P2356UBLRP has confirmed inventory of 957 pieces in stock

For new designs or system refreshes, P2356UBLRP is the appropriate selection. For legacy system maintenance where P2356UBRP inventory exists, direct substitution with P2356UBLRP is electrically and mechanically valid.

Frequently Asked Questions (FAQ)

Q: Can P2356UBLRP be used as a direct replacement for P2356UBRP?

A: Yes. Both parts are electrically and mechanically identical. All voltage ratings, current specifications, capacitance values, and package dimensions match exactly. The primary differences are product status and compliance certifications.

Q: What is the difference between the bulk and tape & reel packaging?

A: Bulk packaging (P2356UBRP) is suitable for manual handling and small-quantity applications. Tape & reel packaging (P2356UBLRP) is designed for automated pick-and-place assembly equipment and high-volume production. The components themselves are identical.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical function. Both parts perform identically in circuit applications.

Q: Are there any circuit design considerations when substituting these parts?

A: No design changes are required. The electrical specifications, including voltage ratings, current handling, and capacitance, are identical. PCB layout and circuit design remain unchanged.

Q: Why is P2356UBRP listed as obsolete?

A: Littelfuse Inc. has transitioned production to the P2356UBLRP variant, which includes improved compliance certifications and tape & reel packaging for modern manufacturing processes.
