TLC372MP Equivalent & Substitute Parts

Part Overview

The TLC372MP 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 (4V ~ 16V single supply, ±2V ~ 8V dual supply) and is designed for precision voltage comparison applications requiring low input offset voltage and minimal input bias current. The TLC372MP is currently in Last Time Buy status, making identification of compatible substitute parts essential for ongoing design support and procurement planning.

Substitute Part Grouping Explanation

Substitution of the TLC372MP is determined by electrical parameter equivalence and package compatibility. The primary substitute identified is the TLC372MDR, which maintains identical electrical specifications across all critical parameters: supply voltage range, input offset voltage, input bias current, output current, quiescent current, and operating temperature range. The substitution is valid based on the following criteria:

Electrical Equivalence: Both parts share the same base product number (TLC372), identical functional specifications, and equivalent performance characteristics across all measured parameters.

Functional Compatibility: Both devices are dual differential comparators with CMOS/MOS/Open-Drain/TTL output configurations, ensuring functional interchangeability in circuit applications.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for equivalent component selection.

Package Consideration: The primary difference between TLC372MP and TLC372MDR is packaging format—through-hole (8-DIP) versus surface mount (8-SOIC)—which affects board-level integration but not electrical performance.

Engineering Selection Recommendations

The TLC372MDR is the direct electrical equivalent to the TLC372MP and is recommended as the primary substitute. The TLC372MP's Last Time Buy status indicates limited future availability, making the TLC372MDR—which maintains Active product status—the appropriate long-term alternative for new designs and ongoing production requirements.

Selection between these parts should be based on board-level integration requirements: the TLC372MP is suitable for through-hole PCB designs, while the TLC372MDR is appropriate for surface-mount assembly processes. Both parts maintain identical electrical performance and regulatory compliance, ensuring functional equivalence in circuit applications.

The TLC372MDR's higher inventory availability (15,936 pcs) compared to the TLC372MP (1,373 pcs) provides improved supply chain reliability for production planning.

Frequently Asked Questions (FAQ)

Q: Can TLC372MDR replace TLC372MP in existing designs?

A: Yes, electrically. The TLC372MDR maintains identical electrical specifications and functional performance. However, the package difference (8-SOIC surface mount versus 8-DIP through hole) requires PCB redesign for physical integration.

Q: What is the primary difference between TLC372MP and TLC372MDR?

A: The packaging format differs: TLC372MP uses through-hole 8-DIP packaging, while TLC372MDR uses surface-mount 8-SOIC packaging. All electrical parameters remain identical.

Q: Why is TLC372MP listed as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued active production of this part number. The TLC372MDR, with Active status, represents the current production equivalent.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring equivalent regulatory qualification.

Q: What supply voltage ranges are supported?

A: Both parts operate across 4V ~ 16V single supply or ±2V ~ 8V dual supply configurations, providing flexibility for various circuit topologies.

Q: What is the input offset voltage specification?

A: Both parts specify a maximum input offset voltage of 5mV at 5V supply, ensuring precision voltage comparison performance.
