Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2106UCTP is determined by exact matching of the following critical electrical and mechanical parameters:

• Voltage - Off State: 170V
• Voltage - Breakover: 250V
• Voltage - On State: 8V
• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 150mA
• Number of Elements: 6
• Capacitance: 30pF, 45pF
• Package / Case: 6-SMD, Gull Wing
• Mounting Type: Surface Mount

The P2106UCLTP meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The P2106UCLTP is the direct equivalent for the obsolete P2106UCTP. Both components share identical electrical specifications and mechanical packaging. The primary distinction is product status: P2106UCLTP is currently active and available, whereas P2106UCTP is obsolete.

For new designs or system refreshes, P2106UCLTP is the appropriate selection. The substitute offers improved compliance status (ROHS3 Compliant versus RoHS non-compliant) and confirmed active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can P2106UCLTP be used as a direct replacement for P2106UCTP?

A: Yes. Both parts are electrically and mechanically identical, with matching voltage ratings (170V off-state, 250V breakover, 8V on-state), current specifications (400A peak pulse at 8/20µs, 100A at 10/1000µs, 150mA hold current), element count (6), capacitance values (30pF, 45pF), and 6-SMD gull wing package configuration.

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

A: The primary differences are packaging format (tube for P2106UCLTP versus unspecified for P2106UCTP), product status (active versus obsolete), and RoHS compliance (ROHS3 Compliant versus non-compliant). Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting P2106UCLTP for P2106UCTP?

A: No compatibility concerns exist. The identical electrical ratings, element configuration, and 6-SMD gull wing package ensure direct PCB compatibility and functional equivalence.

Q: Why is P2106UCTP listed as obsolete?

A: P2106UCTP has been discontinued by the manufacturer. P2106UCLTP represents the active production equivalent and is the recommended source for procurement.
