P1101DF-1 Equivalent & Substitute Parts

Part Overview

The P1101DF-1 is a Transient Voltage Suppressor (TVS) device manufactured by Littelfuse Inc., part of the SIDACtor® series. This component is designed for circuit protection applications, specifically in SLIC (Subscriber Line Interface Circuit) systems. The P1101DF-1 operates at a clamping voltage of 95V and utilizes mixed technology in a surface mount 8-SOIC package.

The P1101DF-1 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this device is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of TVS devices is determined by strict equivalence across the following critical parameters:

• Voltage - Clamping (95V): Must match exactly to ensure proper transient suppression without over-clamping or under-clamping the protected circuit.
• Technology (Mixed Technology): Electrical characteristics and response time are dependent on the technology platform.
• Number of Circuits (1): Determines the internal configuration and pin assignment.
• Package / Case (8-SOIC): Physical and electrical compatibility with PCB layout and thermal management.
• Supplier Device Package (MS-012): Ensures mechanical fit and electrical performance consistency.

The P1101DF-1E is a direct substitute that maintains identical specifications across all critical parameters while offering improved product status and availability.
