TLC372CPW Equivalent & Substitute Parts

Part Overview

The TLC372CPW is a dual differential comparator IC manufactured by Texas Instruments in the LinCMOS™ series. It features CMOS, MOS, open-drain, and TTL output types housed in an 8-TSSOP surface mount package. The device operates across a wide supply voltage range of 3V to 16V (single supply) or ±1.5V to ±8V (dual supply), making it suitable for general-purpose analog comparison applications.

The TLC372CPW is currently in Last Time Buy status, indicating production discontinuation. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain component availability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitute parts for the TLC372CPW are identified based on strict electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

• Dual comparator configuration (2 elements)
• 8-TSSOP surface mount package with identical 0.173" width and 4.40mm dimensions
• Output stage compatibility (CMOS/open-drain architecture)
• Supply voltage range overlap: minimum 3V single supply or ±1.5V dual supply capability
• Input offset voltage specification of 5mV or better
• Output current capability of 20mA or greater
• ROHS3 compliance and identical moisture sensitivity level (MSL 1)

Identified Substitute Parts:

1. TLC372CPWR (Texas Instruments) – Direct manufacturer equivalent with identical electrical specifications and packaging format change from Tube to Cut Tape & Digi-Reel®
2. TS393IPT (STMicroelectronics) – Cross-manufacturer substitute with general-purpose comparator topology, compatible package, and enhanced operating temperature range

Engineering Selection Recommendations

TLC372CPWR (Recommended Primary Substitute)

The TLC372CPWR is the direct equivalent from Texas Instruments with identical electrical specifications and operating parameters to the TLC372CPW. The only difference is packaging format: TLC372CPWR is supplied in Cut Tape & Digi-Reel® format rather than Tube. This part maintains Active product status, ensuring long-term availability and supply chain stability. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are identical. This is the preferred choice for direct replacement in existing designs.

TS393IPT (Alternative Cross-Manufacturer Substitute)

The TS393IPT from STMicroelectronics provides functional equivalence with notable enhancements: extended operating temperature range (-40°C to 125°C versus 0°C to 70°C), lower input bias current (1pA versus 5pA), and significantly reduced quiescent current (25µA versus 400µA). The supply voltage range is marginally extended at the lower end (2.7V minimum versus 3V). The TS393IPT is classified as a general-purpose comparator rather than differential type, but maintains compatible output architecture and identical package specifications. This part is suitable for applications requiring extended temperature operation or lower power consumption. All compliance certifications match the original part.

Frequently Asked Questions (FAQ)

Q: Can TLC372CPWR be used as a direct drop-in replacement for TLC372CPW?

A: Yes. The TLC372CPWR is electrically and functionally identical to the TLC372CPW. The only difference is the packaging format (Cut Tape & Digi-Reel® versus Tube). Both parts have identical pin configurations, electrical specifications, and operating parameters. No circuit modifications are required.

Q: What are the key differences between TLC372CPWR and TS393IPT?

A: Both are dual comparators in 8-TSSOP packages with compatible output stages. Key differences include: (1) TLC372CPWR maintains the differential comparator classification with identical specifications to the original TLC372CPW; (2) TS393IPT is a general-purpose comparator with extended temperature range (-40°C to 125°C), lower input bias current (1pA), and significantly lower quiescent current (25µA). The TS393IPT is suitable for applications requiring enhanced temperature performance or reduced power consumption.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both TLC372CPWR and TS393IPT are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original TLC372CPW specifications.

Q: Can TS393IPT be used in applications with the original 0°C to 70°C temperature specification?

A: Yes. The TS393IPT operating range of -40°C to 125°C fully encompasses the original 0°C to 70°C specification. The part is suitable for this application with additional temperature margin available.

Q: Are there any output type differences between the substitutes?

A: The TLC372CPWR maintains identical output types (CMOS, MOS, Open-Drain, TTL) to the original TLC372CPW. The TS393IPT output types are CMOS and Open-Drain, which are a subset of the original specification. Verify that your circuit design does not require TTL or MOS output characteristics before selecting TS393IPT.

Q: What is the inventory status of these substitute parts?

A: TLC372CPWR has 35,300 pieces in stock. TS393IPT has 21,200 pieces in stock. Both parts are in Active product status with established supply chains.
