P2703UARP Equivalent & Substitute Parts

Part Overview

The P2703UARP 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 150 A (8/20µs) and is currently classified as obsolete. Due to its discontinued status, identifying functionally equivalent active alternatives is essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2703UARP is determined by matching the following critical electrical and mechanical parameters:

• Voltage - Off State: 230V
• Voltage - Breakover: 300V
• Voltage - On State: 8V
• Current - Peak Pulse (8/20µs): 150A
• Current - Peak Pulse (10/1000µs): 45A
• Current - Hold (Ih): 150mA
• Number of Elements: 3
• Package / Case: 6-SMD, Gull Wing
• Mounting Type: Surface Mount

The P2703UALRP meets all specified electrical and mechanical parameters, making it a direct functional equivalent. The primary distinction between these parts is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P2703UALRP is the direct substitute for the P2703UARP. Both components share identical electrical specifications and mechanical packaging. The P2703UALRP is currently in active production status, whereas the P2703UARP is obsolete.

The P2703UALRP offers additional compliance advantages: it meets ROHS3 requirements and is REACH unaffected, compared to the P2703UARP's non-compliant status. For new designs or ongoing procurement, the P2703UALRP is the appropriate selection.

The primary operational difference is packaging format: the P2703UALRP is supplied in Tape & Reel format, whereas the P2703UARP was supplied in bulk packaging. This distinction affects procurement and assembly processes but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the P2703UALRP be used as a direct replacement for the P2703UARP?

A: Yes. Both components have identical electrical ratings (230V off-state, 300V breakover, 150A peak pulse current) and mechanical specifications (6-SMD gull wing package). The P2703UALRP is the active production equivalent.

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

A: The P2703UALRP is the active production version of the obsolete P2703UARP. Electrical and mechanical specifications are identical. The P2703UALRP is supplied in Tape & Reel packaging and meets ROHS3 compliance, whereas the P2703UARP was supplied in bulk packaging and is non-compliant.

Q: Are there any compatibility concerns when switching from P2703UARP to P2703UALRP?

A: No compatibility concerns exist for electrical or mechanical performance. Both components are pin-compatible and functionally equivalent. Packaging format differences (Tape & Reel vs. bulk) affect procurement and assembly logistics only.

Q: Does the Tape & Reel packaging of the P2703UALRP affect circuit performance?

A: No. Packaging format does not affect electrical performance or circuit behavior. The component itself is identical; only the delivery and handling format differs.

Q: Is the P2703UALRP suitable for new designs?

A: Yes. The P2703UALRP is in active production status and meets current compliance standards (ROHS3, REACH unaffected). It is the recommended choice for new designs requiring 230V TVS thyristor functionality.
