TSV6191ICT Equivalent & Substitute Parts

Part Overview

The TSV6191ICT is a general-purpose operational amplifier manufactured by STMicroelectronics, housed in a 5-TSSOP (SC-70-5) surface-mount package. This device features rail-to-rail output capability and is designed for low-power analog signal processing applications. The TSV6191ICT is classified as obsolete, which necessitates identification of active equivalent and substitute components for new designs and production continuity. Equivalent parts must maintain functional compatibility across critical electrical parameters while accommodating the same physical package footprint.

Substitute Part Grouping Explanation

Substitution of the TSV6191ICT is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 5-TSSOP (SC-70-5, SOT-353) surface-mount package to ensure direct PCB footprint compatibility.

Electrical Characteristics: Substitute parts must operate within the supply voltage range of 1.5 V to 5.5 V and maintain rail-to-rail output capability. The slew rate (0.08 V/µs), gain bandwidth product (450 kHz), input bias current (1 pA), and output current capability (63 mA) define the performance envelope for general-purpose signal conditioning applications.

Amplifier Classification: The TSV6191ICT is a general-purpose amplifier with a single circuit. Substitutes must maintain this classification to ensure functional equivalence in typical op-amp applications.

Environmental and Compliance Requirements: All substitute parts must be RoHS3 compliant, have MSL rating of 1 (Unlimited), and operate across the temperature range of -40°C to 85°C or wider.

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalent: TSV6191AICT (STMicroelectronics) — Active product status with identical electrical specifications and improved input offset voltage (800 µV vs. 4 mV).
Cross-Manufacturer Substitutes: Parts from Renesas Electronics (ISL28113FEZ-T7, ISL28113FEZ-T7A, ISL28114FEZ-T7, ISL28114FEZ-T7A), Analog Devices (ADA4051-1AKSZ-R7, MAX4400AXK+T, MAX9620AXK+T), onsemi (LMV931SQ3T2G), and Microchip Technology (MCP6231UT-E/LT) — All feature identical packaging and rail-to-rail output with variations in performance parameters.
