Parameter Comparison

Engineering Selection Recommendations

TLC374CN is the manufacturer-recommended substitute for the discontinued TLC374CNG4. This part maintains full electrical and mechanical compatibility while offering active product status and higher inventory availability (2788 units in stock). The TLC374CN is packaged in tube format and carries ROHS3 compliance.

TLC374CN-A is a parametric equivalent offering identical electrical specifications and mechanical compatibility. This variant is also active and maintains ROHS3 compliance with 1498 units in stock. The TLC374CN-A is suitable for applications requiring the same performance characteristics as the original TLC374CNG4.

Both substitute parts are direct functional replacements suitable for PCB assembly without design modification, provided the original design accommodates the 14-DIP through-hole package format.

Frequently Asked Questions (FAQ)

Q: Can TLC374CN be used as a direct replacement for TLC374CNG4? A: Yes. The TLC374CN is electrically and mechanically identical to the TLC374CNG4, with matching supply voltage ranges, input/output specifications, and 14-DIP package configuration. The primary difference is product status (active vs. discontinued) and packaging format (tube vs. original).

Q: What is the difference between TLC374CN and TLC374CN-A? A: Both parts are parametric equivalents with identical electrical specifications and package dimensions. The suffix "-A" indicates a variant designation from Texas Instruments. Both are suitable for the same applications and offer equivalent performance.

Q: Are the substitute parts compatible with existing PCB designs for TLC374CNG4? A: Yes, provided the original design uses a 14-DIP through-hole socket. The pin configuration, electrical characteristics, and package footprint are identical across all three part numbers.

Q: What is the inventory status of substitute parts? A: TLC374CN has 2788 units in stock, and TLC374CN-A has 1498 units in stock. Both are active products with ongoing availability.

Q: Do the substitute parts meet the same compliance standards? A: Yes. Both TLC374CN and TLC374CN-A are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original TLC374CNG4.
