P2356UBTP Equivalent & Substitute Parts

Part Overview

The P2356UBTP is a 200V off-state TVS thyristor from Littelfuse Inc.'s SIDACtor® series, designed for transient voltage suppression applications. This component features a 6-SMD gull wing package with 250 A peak pulse current capability (8/20µs) and is rated for 150 mA holding current. The part is currently listed as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2356UBTP is determined by strict equivalence across the following critical parameters:

• Voltage ratings: Off-state voltage (200V), breakover voltage (270V), and on-state voltage (8V) must match exactly
• Current specifications: Peak pulse current (8/20µs at 250A and 10/1000µs at 80A) and holding current (150mA) must be identical
• Package configuration: 6-SMD gull wing form factor with Modified MS-013 supplier device package
• Element count: 6 elements required
• Capacitance range: 25pF to 35pF

The P2356UBLTP meets all these criteria and qualifies as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The P2356UBLTP is the direct equivalent substitute for the obsolete P2356UBTP. Both parts are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status and compliance certification. The P2356UBTP is obsolete and RoHS non-compliant, while the P2356UBLTP is active and ROHS3 compliant. For new designs or ongoing production requiring regulatory compliance, the P2356UBLTP is the appropriate selection. The packaging difference (tube versus unspecified for the main part) does not affect functional equivalence or circuit performance.

Frequently Asked Questions (FAQ)

Q: Can P2356UBLTP be used as a direct replacement for P2356UBTP in existing designs?

A: Yes. The P2356UBLTP is electrically and mechanically identical to the P2356UBTP across all specified parameters, including voltage ratings, current ratings, element count, and package configuration. Direct substitution is supported without circuit modification.

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

A: The parts are functionally equivalent. The P2356UBLTP differs in product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant). The P2356UBLTP is supplied in tube packaging, while the original part's packaging format is not specified.

Q: Are there any compatibility concerns with the 6-SMD gull wing package?

A: No. Both parts use the identical 6-SMD gull wing package with Modified MS-013 supplier device package designation. PCB footprints and assembly processes remain unchanged.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance is a regulatory and material composition requirement, not an electrical performance specification. Both parts maintain identical electrical characteristics.

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

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
