TS932BIN Equivalent & Substitute Parts

Part Overview

The TS932BIN 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 automotive-grade applications with AEC-Q100 qualification and operates across a supply voltage range of 2.7 V to 10 V.

The TS932BIN is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance where this component is specified in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS932BIN is evaluated based on the following critical parameters that define functional and mechanical compatibility:

Functional Compatibility Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 2 (dual configuration)
• Output Type: Rail-to-Rail
• Supply Voltage Range: Minimum 2.7 V, Maximum 10 V (substitute must support this range or be compatible within application constraints)

Mechanical Compatibility Criteria:

• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

Regulatory & Compliance Criteria:

• RoHS Compliance: ROHS3 Compliant
• Operating Temperature Range: -40°C to 105°C (automotive-grade operation)

The LMC6442IN/NOPB qualifies as a substitute based on matching amplifier type, circuit count, output configuration, and physical package specifications. Both devices are housed in 8-DIP through-hole packages with identical pitch and dimensions, enabling direct board-level replacement without layout modification.

Engineering Selection Recommendations

TS932BIN (Primary Part - Obsolete)

The TS932BIN is an obsolete product. While inventory remains available (1340 pcs in stock), long-term supply cannot be guaranteed. This device carries automotive-grade qualification (AEC-Q100) and operates across the full temperature range of -40°C to 105°C, making it suitable for demanding automotive applications.

LMC6442IN/NOPB (Active Substitute)

The LMC6442IN/NOPB is an active product from National Semiconductor's LMC® series, ensuring ongoing availability and supply chain stability. This substitute maintains functional and mechanical compatibility through identical package configuration (8-DIP through-hole) and matching dual rail-to-rail amplifier architecture.

Key Differences Affecting Selection:

The LMC6442IN/NOPB exhibits lower power consumption (1.9 µA supply current versus 20 µA) and reduced input bias current (0.005 pA versus 1 pA), making it advantageous for battery-powered or low-power applications. However, it operates at a reduced maximum temperature of 85°C, which may not satisfy automotive-grade thermal requirements in all applications. The TS932BIN 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 faster signal processing.

Substitution Guidance:

For applications where the maximum operating temperature does not exceed 85°C and lower power consumption is beneficial, the LMC6442IN/NOPB provides a direct functional replacement. For applications requiring the full -40°C to 105°C automotive temperature range, alternative substitutes maintaining this specification should be evaluated, or the TS932BIN should be sourced from available inventory while supplies remain.

Frequently Asked Questions (FAQ)

Q: Can the LMC6442IN/NOPB directly replace the TS932BIN on a printed circuit board?

A: Yes. Both devices are housed in 8-DIP (0.300", 7.62mm) through-hole packages with identical pin pitch and dimensions. No PCB layout modification is required for physical installation. Pin-to-pin compatibility must be verified against the specific application schematic to ensure functional equivalence.

Q: What is the primary difference in operating temperature range between these devices?

A: The TS932BIN operates from -40°C to 105°C, while the LMC6442IN/NOPB operates from -40°C to 85°C. Applications requiring operation above 85°C must use the TS932BIN or identify alternative substitutes with extended temperature ratings.

Q: How do the power consumption characteristics compare?

A: The LMC6442IN/NOPB consumes significantly less supply current (1.9 µA per dual channels) compared to the TS932BIN (20 µA per dual channels). This 10-fold reduction in power consumption makes the LMC6442IN/NOPB preferable for battery-powered or energy-constrained applications.

Q: Are there differences in signal processing speed between these devices?

A: Yes. The TS932BIN provides a slew rate of 0.05 V/µs and gain bandwidth product of 100 kHz, while the LMC6442IN/NOPB provides 0.0041 V/µs and 10.5 kHz respectively. Applications requiring faster signal transitions or higher bandwidth should retain the TS932BIN or identify faster alternatives.

Q: What compliance certifications apply to each device?

A: The TS932BIN carries AEC-Q100 automotive qualification and is ROHS3 compliant. The LMC6442IN/NOPB is ROHS3 compliant. Both devices are EAR99 classified and REACH unaffected. Automotive-grade applications requiring AEC-Q100 qualification should verify whether the LMC6442IN/NOPB meets specific qualification requirements for the target application.

Q: Is the TS932BIN still available for new designs?

A: The TS932BIN is classified as obsolete. While current inventory of 1340 pieces is available, this device should not be specified for new designs. The LMC6442IN/NOPB, as an active product, is recommended for new development where functional and thermal requirements align.

Q: What supply voltage ranges are supported by each device?

A: The TS932BIN 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 (1.8 V versus 2.7 V) and higher maximum voltage (11 V versus 10 V), providing greater flexibility in supply voltage selection.
