TS942AIPT Equivalent & Substitute Parts

Part Overview

The TS942AIPT is a general-purpose operational amplifier manufactured by STMicroelectronics, configured as a dual-circuit (2-channel) rail-to-rail output device in an 8-TSSOP surface-mount package. This component is classified as obsolete, indicating that direct procurement from the original manufacturer may be limited or unavailable. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this amplifier.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS942AIPT is determined by strict alignment of the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 8-TSSOP surface-mount package with identical physical dimensions (0.173", 4.40mm Width) to ensure direct PCB footprint compatibility without layout redesign.

Circuit Configuration: The substitute must provide dual-circuit (2-channel) amplifier functionality to match the TS942AIPT's channel count and support equivalent signal processing requirements.

Output Characteristics: Rail-to-rail output capability is required to maintain voltage swing performance across the specified supply voltage range.

Supply Voltage Range: The substitute must operate within or encompass the TS942AIPT supply voltage span of 2.5 V to 10 V to ensure compatibility with existing power distribution designs.

Operating Temperature Range: The substitute must support the -40°C to 85°C operating temperature specification to maintain performance across the intended environmental conditions.

Regulatory Compliance: Both parts must maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity to satisfy procurement and manufacturing standards.

The OP296HRUZ-REEL from Analog Devices Inc. meets all these substitution criteria and is classified as an active product, providing improved supply availability compared to the obsolete TS942AIPT.

Parameter Comparison

Engineering Selection Recommendations

The OP296HRUZ-REEL qualifies as a direct substitute for the TS942AIPT based on matching package geometry, circuit configuration, and regulatory compliance requirements. Both components are ROHS3 compliant and maintain MSL Level 1 (Unlimited) moisture sensitivity classification, satisfying procurement and manufacturing standards.

The OP296HRUZ-REEL is classified as an active product with current manufacturing status, providing superior supply chain availability compared to the obsolete TS942AIPT. This status change eliminates long-lead-time risks and supports sustained production requirements.

The substitute part operates across an expanded supply voltage range (3 V to 12 V versus 2.5 V to 10 V) and supports an extended operating temperature range (-40°C to 125°C versus -40°C to 85°C), offering broader environmental compatibility for existing and future applications.

Both components utilize identical 8-TSSOP surface-mount packaging, enabling direct PCB footprint compatibility without layout modification or redesign.

Frequently Asked Questions (FAQ)

Q: Can the OP296HRUZ-REEL be used as a direct replacement for the TS942AIPT without PCB modifications?

A: Yes. Both components use the 8-TSSOP surface-mount package with identical physical dimensions (0.173", 4.40mm Width). Direct footprint compatibility is confirmed, and no PCB layout changes are required.

Q: What are the key differences between the TS942AIPT and OP296HRUZ-REEL?

A: The OP296HRUZ-REEL is a CMOS amplifier with significantly higher slew rate (0.3 V/µs versus 0.0045 V/µs) and gain bandwidth product (450 kHz versus 10 kHz). The substitute also features lower input offset voltage (35 µV versus 5 mV) and higher input bias current (10 nA versus 1 pA). The OP296HRUZ-REEL supports an expanded supply voltage range (3 V to 12 V) and extended operating temperature range (-40°C to 125°C).

Q: Is the OP296HRUZ-REEL suitable for low-speed, low-power applications originally designed for the TS942AIPT?

A: The OP296HRUZ-REEL meets all substitution criteria for package, circuit configuration, and regulatory compliance. However, the higher slew rate and gain bandwidth product represent performance enhancements beyond the original TS942AIPT specification. Circuit-level validation is necessary to confirm compatibility with specific application requirements.

Q: What is the significance of the TS942AIPT being classified as obsolete?

A: Obsolete status indicates that the TS942AIPT is no longer manufactured or supported by STMicroelectronics. Direct procurement is limited or unavailable. The OP296HRUZ-REEL, classified as active, provides sustained manufacturing support and supply chain reliability.

Q: Are both components compliant with current regulatory standards?

A: Yes. Both the TS942AIPT and OP296HRUZ-REEL are ROHS3 compliant and maintain MSL Level 1 (Unlimited) moisture sensitivity classification, satisfying current procurement and manufacturing standards.

Q: What packaging format is the OP296HRUZ-REEL supplied in?

A: The OP296HRUZ-REEL is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The TS942AIPT packaging format is not specified in the provided data.

Q: Does the expanded supply voltage range of the OP296HRUZ-REEL affect compatibility with existing power distribution designs?

A: The OP296HRUZ-REEL operates across a supply voltage range of 3 V to 12 V, which encompasses the TS942AIPT range of 2.5 V to 10 V. Designs operating within the original 2.5 V to 10 V range remain compatible. Designs requiring operation below 3 V require alternative solutions.
