P3104UCMCTP Equivalent & Substitute Parts

Part Overview

The P3104UCMCTP is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., part of the SIDACtor® series. This component is designed for overvoltage protection applications, featuring dual voltage ratings (275V/550V off-state) with a peak pulse current capability of 400 A at 8/20µs pulse width. The part is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs requiring this protection topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P3104UCMCTP is determined by strict equivalence across the following critical parameters:

• Voltage ratings (breakover and off-state): 350V/700V and 275V/550V respectively
• Peak pulse current capability: 400 A at 8/20µs pulse width
• On-state voltage: 8 V maximum
• Hold current: 150 mA
• Element count: 4 elements
• Capacitance range: 25pF to 45pF
• Package configuration: 6-SMD, Gull Wing (Modified MS-013)
• Mounting technology: Surface Mount

The substitute part P3104UCMCLTP maintains identical electrical and mechanical specifications, with the primary distinction being packaging format (tube versus bulk) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P3104UCMCLTP is the direct functional equivalent of the obsolete P3104UCMCTP. Both components share identical electrical performance characteristics and mechanical specifications. The primary distinction is product lifecycle status: P3104UCMCLTP is actively manufactured and supported by Littelfuse, whereas P3104UCMCTP is obsolete.

For new designs and ongoing system support, P3104UCMCLTP is the appropriate selection. This part offers improved compliance posture, with ROHS3 certification and REACH unaffected status, compared to the non-compliant status of the original part. Packaging is supplied in tube format rather than bulk, which may affect procurement workflows but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Are P3104UCMCTP and P3104UCMCLTP electrically interchangeable?

A: Yes. Both parts are manufactured by Littelfuse and maintain identical electrical specifications across all critical parameters: voltage ratings (350V/700V breakover, 275V/550V off-state), peak pulse current (400 A at 8/20µs), on-state voltage (8 V), and hold current (150 mA).

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

A: The primary differences are product status (P3104UCMCTP is obsolete; P3104UCMCLTP is active) and packaging format (tube versus bulk). Electrical and mechanical specifications are identical. P3104UCMCLTP also carries improved regulatory compliance (ROHS3 Compliant versus RoHS non-compliant).

Q: Can I use P3104UCMCLTP as a direct replacement in existing assemblies designed for P3104UCMCTP?

A: Yes. The 6-SMD Gull Wing package configuration and Modified MS-013 supplier device package are identical. PCB footprints and assembly processes remain unchanged. Electrical performance is equivalent across all operating conditions.

Q: Are there any compliance considerations when switching from P3104UCMCTP to P3104UCMCLTP?

A: P3104UCMCLTP offers enhanced compliance status with ROHS3 certification and REACH unaffected designation. If your application or supply chain requires RoHS compliance, P3104UCMCLTP is the appropriate choice. Both parts share identical ECCN (EAR99) and HTSUS (8541.30.0080) classifications.

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

A: Both P3104UCMCTP and P3104UCMCLTP carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
