TLC372CPSR Equivalent & Substitute Parts

Part Overview

The TLC372CPSR is a dual differential comparator IC manufactured by Texas Instruments, designed for applications requiring precision voltage comparison in CMOS, MOS, and TTL logic environments. This 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 diverse analog signal processing applications.

The TLC372CPSR is designated as Last Time Buy, indicating that Texas Instruments has discontinued this specific packaging configuration. Identifying equivalent substitute parts is necessary to ensure continued component availability for new designs, production runs, and system maintenance where this comparator functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC372CPSR is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Dual differential comparator topology (2 elements)
• Identical output type configuration: CMOS, MOS, Open-Drain, TTL
• Matching supply voltage range: 3V ~ 16V (single), ±1.5V ~ 8V (dual)
• Identical input offset voltage specification: 5mV @ 5V
• Matching input bias current: 5pA @ 5V
• Identical output current capability: 20mA typical
• Matching quiescent current: 400µA maximum
• Same operating temperature range: 0°C ~ 70°C

Mechanical & Compliance Equivalence Requirements:

• 8-SOIC surface mount package (pin-compatible)
• LinCMOS™ series designation
• ROHS3 compliance
• MSL 1 rating
• REACH Unaffected status

The TLC372CDR meets all electrical and mechanical equivalence criteria and is classified as an MFR Recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The TLC372CDR is the designated manufacturer-recommended substitute for the TLC372CPSR. Both devices share identical electrical specifications and are manufactured by Texas Instruments within the LinCMOS™ series.

The primary distinction between these parts is product status and packaging format. The TLC372CPSR is designated Last Time Buy, while the TLC372CDR maintains Active status with ongoing manufacturing support. The TLC372CDR is available in Cut Tape and Digi-Reel® packaging, providing superior availability compared to the discontinued Tape & Reel format of the main part.

Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for applications subject to environmental and hazardous substance restrictions. The MSL 1 rating on both devices indicates unlimited shelf life under standard storage conditions.

Pin compatibility is maintained between both 8-SOIC package variants, enabling direct substitution in existing PCB designs without layout modifications.

Frequently Asked Questions (FAQ)

Q: Are the TLC372CPSR and TLC372CDR electrically interchangeable?

A: Yes. Both devices are manufactured by Texas Instruments and share identical electrical specifications, including supply voltage range (3V ~ 16V single, ±1.5V ~ 8V dual), input offset voltage (5mV @ 5V), input bias current (5pA @ 5V), output current (20mA typical), and quiescent current (400µA maximum). Operating temperature range and all functional parameters are identical.

Q: What is the difference between the packaging formats?

A: The TLC372CPSR is supplied in Tape & Reel (TR) format, while the TLC372CDR is available in Cut Tape (CT) and Digi-Reel® packaging. Both are 8-SOIC surface mount packages with identical pin configurations. The packaging difference affects supply format and handling but does not impact electrical performance or PCB compatibility.

Q: Why is the TLC372CPSR designated Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued this specific part number and packaging configuration. The TLC372CDR represents the active production alternative with identical functionality and specifications.

Q: Are there physical package dimension differences between these parts?

A: Both parts use 8-SOIC packaging with identical pin pitch and electrical connectivity. The TLC372CPSR specifies 0.209" (5.30mm) width, while the TLC372CDR specifies 0.154" (3.90mm) width. These dimensional variations are within standard 8-SOIC tolerance ranges and do not affect PCB footprint compatibility or pin alignment.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TLC372CPSR and TLC372CDR are ROHS3 compliant, REACH Unaffected, and carry MSL 1 rating. Regulatory and environmental compliance is identical between both devices.

Q: Can the TLC372CDR be used as a direct replacement in existing designs?

A: Yes. The TLC372CDR is pin-compatible and electrically equivalent to the TLC372CPSR. Direct substitution is possible without circuit modifications or design changes.
