Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS932AIN is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 8-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Pin count and spacing must match for direct board-level replacement

Functional Compatibility:

• Amplifier type: General Purpose
• Number of circuits: 2 (dual configuration)
• Output type: Rail-to-Rail

Electrical Operating Range:

• Supply voltage span must encompass or exceed the TS932AIN range (2.7 V to 10 V minimum)
• Operating temperature range must support the application requirements

Regulatory & Compliance:

• RoHS3 compliance status
• ECCN and HTSUS classifications for procurement alignment

The LMC6442IN/NOPB meets all mechanical and functional substitution criteria. Both devices share identical package geometry, dual general-purpose amplifier architecture, and rail-to-rail output capability. The LMC6442IN/NOPB operates within a compatible supply voltage range (1.8 V to 11 V) and maintains through-hole DIP mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: LMC6442IN/NOPB

The LMC6442IN/NOPB is the direct functional equivalent for TS932AIN replacement. Both devices are classified as general-purpose dual operational amplifiers with rail-to-rail output in identical 8-DIP through-hole packages. The LMC6442IN/NOPB maintains active product status, ensuring long-term availability and supply chain continuity.

Compliance Considerations:

The TS932AIN carries AEC-Q100 automotive qualification and operates to 105°C. The LMC6442IN/NOPB operates to 85°C maximum junction temperature. Applications requiring the full 105°C operating range must evaluate whether the reduced upper temperature limit of the LMC6442IN/NOPB is acceptable for the specific use case.

Both devices are ECCN EAR99 classified and share identical HTSUS codes (8542.33.0001), supporting equivalent procurement and export compliance pathways.

Performance Trade-offs:

The LMC6442IN/NOPB exhibits significantly lower supply current (1.9 µA versus 20 µA per dual channels), lower input bias current (0.005 pA versus 1 pA), and reduced input offset voltage (1.5 mV versus 3 mV). These characteristics reflect micropower design optimization. Conversely, the TS932AIN provides higher slew rate (0.05 V/µs versus 0.0041 V/µs) and greater gain bandwidth product (100 kHz versus 10.5 kHz), supporting higher-speed signal processing applications.

Circuit designs dependent on the TS932AIN's higher bandwidth or slew rate performance require detailed evaluation of the LMC6442IN/NOPB's reduced dynamic characteristics before substitution.

Frequently Asked Questions (FAQ)

Q: Can the LMC6442IN/NOPB directly replace the TS932AIN on existing PCBs?

A: Yes, mechanical and pin-level compatibility is direct. Both devices use 8-DIP (0.300", 7.62mm) through-hole packages with identical pinouts for dual general-purpose amplifiers. No PCB modifications are required for physical installation.

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

A: The LMC6442IN/NOPB is optimized for micropower operation, consuming 1.9 µA supply current compared to the TS932AIN's 20 µA. The TS932AIN provides higher bandwidth (100 kHz versus 10.5 kHz) and faster slew rate (0.05 V/µs versus 0.0041 V/µs). Applications requiring high-speed signal processing may not be suitable for LMC6442IN/NOPB substitution.

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

A: The LMC6442IN/NOPB is not explicitly qualified to AEC-Q100 standards. The TS932AIN carries automotive qualification. Applications requiring automotive-grade components must verify whether the LMC6442IN/NOPB meets specific automotive qualification requirements for the intended application.

Q: What is the maximum operating temperature difference?

A: The TS932AIN operates to 105°C, while the LMC6442IN/NOPB operates to 85°C maximum junction temperature. Applications operating above 85°C require confirmation that the reduced temperature range is acceptable.

Q: Are both devices RoHS compliant?

A: The TS932AIN is ROHS3 compliant. RoHS compliance status for the LMC6442IN/NOPB is not provided in the available specifications. Procurement documentation should be verified for RoHS compliance confirmation.

Q: What supply voltage ranges are supported?

A: The TS932AIN operates from 2.7 V to 10 V. The LMC6442IN/NOPB operates from 1.8 V to 11 V. The LMC6442IN/NOPB supports lower minimum voltage and higher maximum voltage, providing broader supply range compatibility.

Q: Can I use the LMC6442IN/NOPB in a design originally specified for TS932AIN?

A: Direct substitution is mechanically and functionally compatible. However, circuit performance must be re-evaluated based on the LMC6442IN/NOPB's reduced bandwidth, lower slew rate, and different input bias current characteristics. Designs with tight bandwidth or slew rate requirements may require circuit redesign or alternative component selection.
