TLC372CP Equivalent & Substitute Parts

Part Overview

The TLC372CP is a dual differential comparator IC manufactured by Texas Instruments, utilizing LinCMOS™ technology in an 8-DIP through-hole package. This component operates across a wide supply voltage range of 3V to 16V (single supply) or ±1.5V to 8V (dual supply), making it suitable for analog signal comparison applications in industrial and consumer electronics. The device is currently in Last Time Buy status, indicating discontinued production. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain component availability for new production runs and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC372CP is determined by electrical parameter equivalence and package compatibility. The primary substitute identified is the TLC372CDR, which shares the identical base product number (TLC372) and maintains all critical electrical specifications:

Key Substitution Criteria:

• Identical differential comparator architecture with 2 elements
• Matching output type configuration (CMOS, MOS, Open-Drain, TTL)
• Equivalent supply voltage range (3V ~ 16V single, ±1.5V ~ 8V dual)
• Identical input offset voltage specification (5mV @ 5V)
• Matching input bias current (5pA @ 5V)
• Equivalent output current capability (20mA typical)
• Same quiescent current specification (400µA maximum)
• Identical operating temperature range (0°C ~ 70°C)
• Equivalent regulatory compliance (ROHS3, REACH Unaffected, EAR99)

The primary difference between TLC372CP and TLC372CDR is the package format: TLC372CP uses 8-DIP through-hole mounting, while TLC372CDR uses 8-SOIC surface-mount packaging. This distinction requires PCB layout and assembly process modifications but does not affect electrical functionality.

Parameter Comparison

Engineering Selection Recommendations

The TLC372CDR is the manufacturer-recommended substitute for the TLC372CP. Both components maintain identical electrical specifications and regulatory compliance status (ROHS3 Compliant, REACH Unaffected, EAR99 classification). The TLC372CDR offers the additional advantage of Active product status, ensuring continued availability and manufacturing support from Texas Instruments, whereas the TLC372CP is in Last Time Buy status.

Selection between these parts depends on PCB assembly requirements. The TLC372CP is appropriate for through-hole assembly processes and legacy designs utilizing DIP sockets. The TLC372CDR is suitable for surface-mount assembly processes and modern PCB designs requiring higher component density. Both parts are electrically interchangeable when appropriate package footprints and assembly methods are employed.

Frequently Asked Questions (FAQ)

Q: Can TLC372CDR directly replace TLC372CP in existing designs?

A: Electrical substitution is complete; however, package format differs. TLC372CP uses 8-DIP through-hole packaging while TLC372CDR uses 8-SOIC surface-mount packaging. Direct socket replacement is not possible without PCB redesign and assembly process modification.

Q: Are the electrical specifications identical between TLC372CP and TLC372CDR?

A: Yes. Both parts share identical supply voltage ranges (3V ~ 16V single, ±1.5V ~ 8V dual), input offset voltage (5mV @ 5V), input bias current (5pA @ 5V), output current (20mA typical), quiescent current (400µA maximum), and operating temperature range (0°C ~ 70°C).

Q: Why is TLC372CP listed as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued production of this part number. The TLC372CDR remains in Active status and represents the current manufacturing equivalent.

Q: What is the pin-to-pin compatibility between these parts?

A: Pin assignments are functionally equivalent between the 8-DIP and 8-SOIC packages for the TLC372 base product. However, physical package dimensions differ significantly, requiring PCB layout modifications.

Q: Are both parts RoHS compliant?

A: Yes. Both TLC372CP and TLC372CDR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Which part should be selected for new designs?

A: TLC372CDR is recommended for new designs due to Active product status and continued manufacturer support. TLC372CP should be reserved for legacy system maintenance only.
