P2103UBTP Equivalent & Substitute Parts

Part Overview

The P2103UBTP is a Transient Voltage Suppressor (TVS) thyristor from Littelfuse Inc., part of the SIDACtor® series. This component is designed for overvoltage protection applications requiring 170V off-state voltage rating and 250A peak pulse current capability in a 6-SMD gull wing surface mount package. The P2103UBTP is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2103UBTP is determined by electrical and mechanical parameter equivalence. The following criteria establish direct substitutability:

• Voltage ratings: Breakover voltage of 250V, off-state voltage of 170V, and on-state voltage of 8V must be identical
• Current specifications: Peak pulse current (8/20µs) of 250A and (10/1000µs) of 80A must match
• Hold current: 150mA threshold requirement
• Element count: 3 elements required
• Capacitance range: 55pF to 85pF
• Package configuration: 6-SMD gull wing surface mount only
• Supplier device package: Modified MS-013

The P2103UBLTP meets all these criteria and qualifies as a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The P2103UBLTP is the direct substitute for the obsolete P2103UBTP. Both parts are electrically and mechanically identical across all specified parameters. The primary distinction is product status and regulatory compliance:

The P2103UBTP is obsolete and RoHS non-compliant. The P2103UBLTP is active in production and ROHS3 compliant, making it the appropriate selection for new designs and ongoing procurement. The P2103UBLTP is supplied in tube packaging, whereas the original part number does not specify packaging format.

Both parts share identical electrical performance, package configuration, and environmental ratings, ensuring direct interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can P2103UBLTP replace P2103UBTP in existing designs?
