Substitute Part Grouping Explanation

Substitute parts for the TLC3702QYPCT must satisfy the following criteria to ensure functional and mechanical compatibility:

• Functional Equivalence: Dual-channel general-purpose CMOS comparator architecture
• Electrical Parameters: Supply voltage range of 4V ~ 16V, input offset voltage ≤ 5mV, output type supporting CMOS/Push-Pull/TTL logic levels
• Performance Specifications: Propagation delay ≤ 4.5µs, quiescent current ≤ 90µA, CMRR ≥ 84dB
• Package Compatibility: 8-SOIC surface mount package (0.154", 3.90mm width)
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status
• Operating Temperature: Full industrial range -55°C ~ 125°C

The primary substitute identified is the TLC3702MDR, which maintains identical electrical specifications and package configuration while offering active product status and higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The TLC3702MDR is the direct functional equivalent of the TLC3702QYPCT. Both parts share identical electrical specifications, package configuration, and regulatory compliance certifications. The primary distinction is product lifecycle status: the TLC3702QYPCT is designated Last Time Buy, while the TLC3702MDR maintains Active status with significantly higher inventory availability (19,212 units versus 906 units).

For new designs or production runs requiring extended component availability, the TLC3702MDR is the appropriate selection. For existing designs currently using the TLC3702QYPCT, direct substitution with the TLC3702MDR requires no circuit modifications, as all electrical and mechanical parameters are identical.
