TS932IN Equivalent & Substitute Parts

Part Overview

The TS932IN is a general-purpose operational amplifier manufactured by STMicroelectronics, featuring dual circuits in a rail-to-rail configuration housed in an 8-Mini DIP package. This device is designed for applications requiring low-power amplification with automotive-grade qualification (AEC-Q100). The TS932IN is classified as an obsolete product, necessitating identification of functionally compatible alternatives for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS932IN is determined by the following critical parameters that must align between the main part and substitute candidates:

Mandatory Compatibility Parameters:

• Amplifier Type: General Purpose
• Number of Circuits: 2
• Output Type: Rail-to-Rail
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Voltage Supply Range: Overlapping operational envelope

Functional Alignment: The LMC6442IN/NOPB qualifies as a substitute based on matching the core functional architecture (dual-channel, general-purpose, rail-to-rail operational amplifier) and identical physical packaging (8-DIP through-hole). Both devices operate within compatible supply voltage ranges and share the same pin configuration, enabling direct board-level replacement without layout modification.

Engineering Selection Recommendations

Primary Substitute: LMC6442IN/NOPB

The LMC6442IN/NOPB is the qualified substitute for the TS932IN based on the following engineering criteria:

Functional Compatibility: Both devices are dual-channel, general-purpose operational amplifiers with rail-to-rail output capability. The identical 8-DIP through-hole package ensures mechanical and electrical pin compatibility without requiring PCB redesign.

Supply Voltage Compatibility: The TS932IN operates within 2.7 V to 10 V. The LMC6442IN/NOPB operates within 1.8 V to 11 V, providing a broader supply envelope that encompasses the original device's operating range.

Product Status Advantage: The LMC6442IN/NOPB maintains active product status with ongoing manufacturer support, ensuring long-term availability and supply chain continuity compared to the obsolete TS932IN.

Compliance and Certification: Both devices carry ROHS3 compliance and EAR99 export classification. The TS932IN includes AEC-Q100 automotive qualification; the LMC6442IN/NOPB does not carry this certification. Applications requiring automotive-grade qualification must evaluate this distinction independently.

Performance Trade-offs: The LMC6442IN/NOPB exhibits lower power consumption (1.9 µA vs. 20 µA supply current) and superior input characteristics (0.005 pA input bias vs. 1 pA; 1.5 mV input offset vs. 10 mV). However, the LMC6442IN/NOPB provides reduced bandwidth (10.5 kHz vs. 100 kHz) and lower slew rate (0.0041 V/µs vs. 0.05 V/µs). Applications with bandwidth or slew rate requirements exceeding 10.5 kHz or 0.0041 V/µs must confirm compatibility with the substitute device specifications.

Temperature Range Consideration: The TS932IN operates to 105°C; the LMC6442IN/NOPB operates to 85°C. Applications requiring operation above 85°C require alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the LMC6442IN/NOPB be used as a direct replacement for the TS932IN?

A: The LMC6442IN/NOPB is mechanically and electrically compatible for direct board-level substitution due to identical 8-DIP packaging and pin configuration. However, performance differences in bandwidth, slew rate, and maximum operating temperature must be evaluated against application requirements.

Q: What are the key differences between these two devices?

A: The primary differences are: (1) Product Status—TS932IN is obsolete; LMC6442IN/NOPB is active; (2) Power Consumption—LMC6442IN/NOPB consumes significantly less supply current (1.9 µA vs. 20 µA); (3) Bandwidth—TS932IN provides 100 kHz vs. 10.5 kHz for LMC6442IN/NOPB; (4) Operating Temperature—TS932IN rated to 105°C vs. 85°C for LMC6442IN/NOPB; (5) Automotive Qualification—TS932IN carries AEC-Q100; LMC6442IN/NOPB does not.

Q: Is the LMC6442IN/NOPB suitable for automotive applications?

A: The LMC6442IN/NOPB does not carry AEC-Q100 automotive qualification. Applications requiring automotive-grade components must confirm alternative solutions or obtain specific qualification documentation from the manufacturer.

Q: Will the LMC6442IN/NOPB work in my circuit designed for the TS932IN?

A: Pin compatibility is confirmed. However, circuit performance depends on application bandwidth and slew rate requirements. Applications operating above 10.5 kHz or requiring slew rates exceeding 0.0041 V/µs may experience performance degradation. Applications operating above 85°C will exceed the LMC6442IN/NOPB maximum temperature rating.

Q: What is the supply voltage compatibility between these devices?

A: The TS932IN operates from 2.7 V to 10 V. The LMC6442IN/NOPB operates from 1.8 V to 11 V. The LMC6442IN/NOPB accommodates the full TS932IN supply range and extends compatibility to lower and higher supply voltages.

Q: Are there any compliance or regulatory differences?

A: Both devices are ROHS3 compliant and carry EAR99 export classification. The TS932IN includes AEC-Q100 automotive qualification; the LMC6442IN/NOPB does not. Applications subject to automotive qualification requirements must address this distinction.

Q: What packaging options are available for these devices?

A: Both the TS932IN and LMC6442IN/NOPB are supplied in 8-DIP (0.300", 7.62mm) through-hole packages. No alternative package options are provided in this substitution analysis.
