TS942IPT Equivalent & Substitute Parts

Part Overview

The TS942IPT is a general-purpose operational amplifier manufactured by STMicroelectronics, configured as a dual-circuit (2-channel) rail-to-rail amplifier in an 8-TSSOP surface-mount package. This device is classified as obsolete, indicating that it is no longer in active production. Due to its obsolete status, identifying functionally compatible substitute components is essential for design continuity, system maintenance, and procurement of replacement units for existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS942IPT is determined by the following critical parameters that must align between the main part and substitute components:

Package Compatibility: The substitute part must utilize the 8-TSSOP surface-mount package with identical physical dimensions (0.173", 4.40mm Width) to ensure direct PCB compatibility without layout modifications.

Dual-Circuit Configuration: The substitute must contain exactly 2 operational amplifier circuits to match the channel count of the original device.

Rail-to-Rail Output: The substitute must provide rail-to-rail output capability to maintain signal swing characteristics within the supply voltage range.

Supply Voltage Range: The substitute must operate within or encompass the 2.5 V to 10 V supply span of the original part. Substitutes with extended supply ranges remain compatible.

Surface-Mount Technology: The substitute must be configured for surface-mount assembly to align with manufacturing processes and PCB design.

Regulatory Compliance: The substitute must maintain ROHS3 compliance and MSL 1 rating to satisfy environmental and handling requirements.

The OP296HRUZ-REEL from Analog Devices Inc. satisfies all substitution criteria through identical package geometry, dual-circuit architecture, rail-to-rail output configuration, compatible supply voltage range, surface-mount technology, and equivalent regulatory compliance status.

Selection of the OP296HRUZ-REEL as a substitute for the TS942IPT is appropriate for applications requiring dual-channel, rail-to-rail amplification within the specified supply voltage and temperature operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the OP296HRUZ-REEL be used as a direct replacement for the TS942IPT without PCB modifications?

A: Yes. Both devices utilize identical 8-TSSOP package geometry with matching pin configurations and physical dimensions (0.173", 4.40mm Width). Direct PCB substitution is possible without layout changes.

Q: What is the primary reason for substituting the TS942IPT?

A: The TS942IPT is classified as obsolete and is no longer in active production. The OP296HRUZ-REEL maintains active product status, ensuring continued availability and supply chain reliability.

Q: Are there differences in electrical performance between the TS942IPT and OP296HRUZ-REEL?

A: Both devices provide dual-channel, rail-to-rail amplification within compatible supply voltage ranges. The OP296HRUZ-REEL exhibits higher slew rate (0.3 V/µs versus 0.0045 V/µs) and gain bandwidth product (450 kHz versus 10 kHz), along with lower input offset voltage (35 µV versus 10 mV). These differences reflect the CMOS architecture of the substitute versus the general-purpose design of the original part.

Q: What is the minimum supply voltage requirement for the OP296HRUZ-REEL?

A: The OP296HRUZ-REEL requires a minimum supply voltage of 3 V, compared to 2.5 V for the TS942IPT. Applications operating at 2.5 V supply voltage require verification of compatibility with the substitute device.

Q: Do both devices meet the same regulatory compliance standards?

A: Yes. Both the TS942IPT and OP296HRUZ-REEL are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and handling requirements.

Q: What is the maximum operating temperature for each device?

A: The TS942IPT operates from -40°C to 85°C. The OP296HRUZ-REEL extends the maximum operating temperature to 125°C, providing enhanced thermal performance for high-temperature applications.

Q: Are both devices available in tape and reel packaging?

A: Yes. Both the TS942IPT and OP296HRUZ-REEL are supplied in Tape & Reel (TR) packaging for automated assembly processes.
