P2703UBTP Equivalent & Substitute Parts

Part Overview

The P2703UBTP is a 230V 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 a peak pulse current rating of 250 A (8/20µs) and is currently classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is essential for ongoing system maintenance, redesigns, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P2703UBTP is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part P2703UBLTP maintains identical specifications in the following key areas:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current ratings (both 8/20µs and 10/1000µs)
• Hold current (Ih)
• Number of elements and capacitance values
• Physical package configuration (6-SMD, gull wing)
• Supplier device package designation (Modified MS-013)
• Moisture sensitivity level

The primary distinction between these parts is packaging format and product status, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The P2703UBLTP is the direct substitute for the obsolete P2703UBTP. Both parts are electrically and mechanically identical across all specified parameters. Selection of P2703UBLTP is supported by the following factors:

• Active product status ensures ongoing availability and manufacturer support
• ROHS3 compliance meets current environmental and regulatory requirements
• Tube packaging provides standard handling and storage conditions for surface mount components
• Identical electrical performance maintains circuit functionality without redesign

For applications requiring the P2703UBTP, transition to P2703UBLTP without modification to PCB layout, schematic, or assembly processes.

Frequently Asked Questions (FAQ)

Q: Can P2703UBLTP be used as a direct replacement for P2703UBTP?

A: Yes. Both parts are electrically and mechanically equivalent. All voltage ratings, current ratings, element count, capacitance values, and physical package specifications are identical. The substitute part is currently in active production status.

Q: What is the difference between P2703UBTP and P2703UBLTP?

A: The primary differences are product status (obsolete vs. active), RoHS compliance level (non-compliant vs. ROHS3 compliant), and packaging format (unspecified vs. tube). Electrical and mechanical specifications are identical.

Q: Does the packaging format change affect PCB assembly?

A: No. Both parts use the same 6-SMD gull wing package configuration and Modified MS-013 supplier device package. Tube packaging is a standard handling format that does not affect component placement, soldering, or circuit performance.

Q: Are there any compliance considerations when switching to P2703UBLTP?

A: P2703UBLTP is ROHS3 compliant and REACH unaffected, meeting current environmental regulations. If your application or region requires RoHS compliance, P2703UBLTP satisfies these requirements.

Q: What is the inventory status of these parts?

A: P2703UBTP has 773 pieces in stock (obsolete status). P2703UBLTP has 619 pieces in stock (active status). For new designs or ongoing procurement, P2703UBLTP is the recommended choice.
