Engineering Selection Recommendations

TLC372MDR is the primary parametric equivalent to TLC372MDREP. Both devices are manufactured by Texas Instruments with identical electrical specifications, operating temperature range (-55°C ~ 125°C), and supply voltage parameters. The TLC372MDR is available in higher inventory (15936 units) and maintains Tape & Reel packaging. This part is recommended as the first substitution choice for direct replacement.

TLC372MDRG4 is a parametric equivalent with identical electrical specifications but is discontinued at DiGi Electronics and available in lower inventory (1778 units). This part is suitable only when supply chain constraints require alternative packaging formats (Cut Tape & Digi-Reel®).

NCS3402DR2G (onsemi) is a manufacturer-recommended alternative with functional equivalence. This part features a lower minimum supply voltage (2.5V vs. 4V), lower input offset voltage (3.6mV @ 15V), and significantly lower quiescent current (640nA vs. 400µA). The operating temperature range is -40°C ~ 125°C. Selection of this part requires verification that the application does not depend on the TLC372MDREP's specific input offset or quiescent current characteristics.

TS372CDT and TS372IDT (STMicroelectronics) are manufacturer-recommended alternatives with differential comparator functionality. Both parts have a lower minimum supply voltage (3V vs. 4V), higher input offset voltage (10mV @ 5V vs. 5mV @ 5V), and lower input bias current (1pA vs. 5pA). TS372CDT operates at 0°C ~ 70°C, while TS372IDT operates at -40°C ~ 125°C. Selection requires confirmation that the application tolerates the higher input offset voltage specification.

All substitute parts maintain ROHS3 compliance and 8-SOIC surface-mount package compatibility. Product status verification is required for TLC372MDRG4 due to discontinuation status.

Frequently Asked Questions (FAQ)

Q: Can TLC372MDR be used as a direct replacement for TLC372MDREP?

A: Yes. TLC372MDR is a parametric equivalent with identical electrical specifications, operating temperature range, and supply voltage parameters. Both are manufactured by Texas Instruments and housed in the 8-SOIC package. The primary difference is packaging format (Tape & Reel for both) and inventory availability.

Q: What are the key differences between TLC372MDREP and NCS3402DR2G?

A: NCS3402DR2G is manufactured by onsemi and differs in the following parameters: minimum supply voltage is 2.5V (vs. 4V), input offset voltage is 3.6mV @ 15V (vs. 5mV @ 5V), input bias current is 250pA @ 15V (vs. 5pA @ 5V), output current is 10mA (vs. 20mA), and quiescent current is 640nA (vs. 400µA). The output type is limited to open-drain. These differences require application-level verification before substitution.

Q: Are TS372CDT and TS372IDT interchangeable with TLC372MDREP?

A: Both TS372 variants are functionally equivalent comparators but have different operating temperature ranges. TS372CDT operates at 0°C ~ 70°C, while TS372IDT operates at -40°C ~ 125°C. Both have higher input offset voltage (10mV @ 5V vs. 5mV @ 5V) and lower minimum supply voltage (3V vs. 4V). Selection depends on application temperature requirements and offset voltage tolerance.

Q: What is the impact of packaging format differences?

A: TLC372MDREP, TLC372MDR, and NCS3402DR2G are supplied in Tape & Reel (TR) format. TLC372MDRG4, TS372CDT, and TS372IDT are supplied in Cut Tape (CT) & Digi-Reel® format. Both formats are compatible with standard PCB assembly equipment. Format selection is determined by production volume and assembly line capabilities.

Q: Is TLC372MDRG4 recommended for new designs?

A: TLC372MDRG4 is discontinued at DiGi Electronics and should not be selected for new designs. Use TLC372MDR or alternative active-status parts for ongoing production.

Q: What compliance certifications apply to all substitute parts?

A: All listed parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001. Moisture sensitivity level is 1 (Unlimited) for all parts.
