P2106UBTP Equivalent & Substitute Parts

Part Overview

The P2106UBTP is a 170V off-state, 250A peak pulse TVS thyristor from Littelfuse Inc., part of the SIDACtor® series. This component is designed for transient voltage suppression in 6-SMD gull wing surface mount packaging. The part is currently obsolete, making identification of compatible substitutes essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P2106UBTP is determined by strict equivalence across electrical and mechanical parameters. The substitute part P2106UBLTP maintains identical specifications for all critical performance characteristics: off-state voltage, breakover voltage, on-state voltage, peak pulse currents, hold current, element count, capacitance range, and package geometry. The only difference is packaging format (tube versus unspecified for the original) and product status (active versus obsolete). Both parts conform to the Modified MS-013 supplier device package specification and are manufactured by Littelfuse Inc. within the SIDACtor® series.

Parameter Comparison

Engineering Selection Recommendations

The P2106UBLTP is the direct functional equivalent to the obsolete P2106UBTP. All electrical performance parameters and mechanical specifications are identical. The P2106UBLTP is currently in active production status, ensuring availability for new procurement and system support. Additionally, the P2106UBLTP carries ROHS3 compliance, whereas the P2106UBTP is non-compliant. For applications subject to RoHS regulations or requiring components from active product lines, the P2106UBLTP is the appropriate selection. Both parts share identical ECCN (EAR99) and HTSUS (8541.30.0080) classifications.

Frequently Asked Questions (FAQ)

Q: Can P2106UBLTP directly replace P2106UBTP in existing designs? A: Yes. All electrical parameters (voltage ratings, current ratings, hold current) and mechanical specifications (package type, mounting method, element count) are identical between the two parts.

Q: What is the difference between P2106UBTP and P2106UBLTP? A: The primary differences are product status (obsolete versus active) and RoHS compliance (non-compliant versus ROHS3 compliant). The packaging format differs (unspecified versus tube), but the component specifications remain equivalent.

Q: Are there any compatibility concerns with PCB layout or assembly? A: No. Both parts use identical 6-SMD gull wing packaging in the Modified MS-013 supplier device package. PCB footprints, reflow profiles, and assembly processes remain unchanged.

Q: Which part should be selected for new designs? A: The P2106UBLTP should be selected for new designs due to its active product status and ROHS3 compliance certification.

Q: Is the capacitance specification identical? A: Yes. Both parts specify capacitance values of 25pF and 35pF.
