TLC372CPWRG4 Equivalent & Substitute Parts

Part Overview

The TLC372CPWRG4 is a dual differential comparator IC manufactured by Texas Instruments, housed in an 8-TSSOP surface mount package. This device features CMOS, MOS, and open-drain TTL output configurations suitable for general signal comparison applications. The part is currently discontinued at DiGi Electronics, necessitating identification of equivalent alternatives that maintain functional and electrical compatibility. Substitute parts must match the core electrical specifications and package form factor to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC372CPWRG4 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Dual comparator configuration (2 elements)
• Supply voltage range overlap: minimum 3V to 16V single supply or ±1.5V to ±8V dual supply
• Input offset voltage maximum of 5mV or better
• Output type compatibility: CMOS, MOS, or open-drain configurations
• Output current capability of 20mA or greater

Physical Compatibility Requirements:

• 8-TSSOP package form factor (0.173" width, 4.40mm)
• Surface mount technology

Regulatory & Compliance Requirements:

• ROHS3 compliance
• MSL rating of 1 or equivalent

Substitute parts are grouped into two categories: parametric equivalents (identical electrical specifications) and manufacturer-recommended alternatives (functionally compatible with minor specification variations).

Parameter Comparison

Engineering Selection Recommendations

TLC372CPWR (Parametric Equivalent)

The TLC372CPWR is the direct parametric equivalent to the TLC372CPWRG4. Both parts share identical electrical specifications, including supply voltage range, input offset voltage, input bias current, output current, and quiescent current. The primary distinction is product status: TLC372CPWR is currently active with 35,300 units in stock, whereas the TLC372CPWRG4 is discontinued. The packaging differs only in supplier format (Cut Tape and Digi-Reel versus standard packaging), with no impact on electrical or mechanical compatibility. This part is the preferred direct replacement.

TS393IPT (Manufacturer-Recommended Alternative)

The TS393IPT is a general-purpose dual comparator manufactured by STMicroelectronics that meets the core substitution criteria. Key advantages include lower quiescent current consumption (25µA versus 400µA), superior input bias current performance (1pA versus 5pA), and an extended operating temperature range (-40°C to 125°C versus 0°C to 70°C). The supply voltage range is marginally broader (2.7V minimum versus 3V minimum). The output type is limited to CMOS and open-drain, excluding TTL output capability present in the TLC372CPWRG4. All parts maintain ROHS3 compliance and MSL rating 1. Selection of the TS393IPT is appropriate when lower power consumption or extended temperature operation is required, provided TTL output is not a functional requirement.

Frequently Asked Questions (FAQ)

Q: Can TLC372CPWR be used as a direct replacement for TLC372CPWRG4?

A: Yes. The TLC372CPWR is a parametric equivalent with identical electrical specifications and the same 8-TSSOP package form factor. The only difference is product status (active versus discontinued) and supplier packaging format. Direct substitution is supported without circuit modification.

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

A: Both are dual comparators in 8-TSSOP packages with compatible supply voltage ranges and output current ratings. The TS393IPT offers lower quiescent current (25µA versus 400µA), better input bias current performance (1pA versus 5pA), and extended operating temperature range (-40°C to 125°C). However, the TS393IPT output type is limited to CMOS and open-drain, whereas TLC372CPWR supports CMOS, MOS, open-drain, and TTL outputs. Selection depends on whether TTL output capability is required.

Q: Are all substitute parts available in the same 8-TSSOP package?

A: Yes. TLC372CPWR and TS393IPT are both available in 8-TSSOP (0.173", 4.40mm width) surface mount packages, ensuring mechanical compatibility with the original TLC372CPWRG4 footprint.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both TLC372CPWR and TS393IPT are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level), matching the compliance profile of the TLC372CPWRG4.

Q: Which substitute should be selected for low-power applications?

A: The TS393IPT is the appropriate choice for power-sensitive designs, offering significantly lower quiescent current consumption (25µA maximum versus 400µA). This part is suitable when extended battery life or reduced thermal dissipation is a design priority, provided TTL output is not required.

Q: What is the operating temperature range difference between substitutes?

A: The TLC372CPWR maintains the original operating range of 0°C to 70°C. The TS393IPT extends this to -40°C to 125°C, supporting applications requiring operation in extreme temperature environments. Selection should align with the target application's thermal requirements.
