Substitute Part Grouping Explanation

Substitution of the MAX970ESD-T is determined by strict equivalence across the following critical parameters:

• Package and Pinout: 14-SOIC surface mount package with identical pin configuration
• Functional Elements: Four independent general-purpose comparators
• Output Configuration: Open-drain, rail-to-rail output topology
• Electrical Specifications: Matching supply voltage range (1.6V ~ 5.5V), input offset voltage (7mV @ 5.5V), input bias current (0.05µA @ 5.5V), quiescent current (18µA), propagation delay (20µs), and hysteresis (±1mV)
• Compliance and Certifications: ROHS3 compliance, MSL Level 1, and REACH unaffected status

The MAX970ESD+T qualifies as a parametric equivalent based on identical electrical performance and package specifications. The primary distinction is packaging format: the substitute part is supplied in Tape & Reel (TR) format with active product status, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The MAX970ESD+T is a direct parametric equivalent to the MAX970ESD-T for applications requiring four general-purpose comparators with open-drain, rail-to-rail output in a 14-SOIC package. Both parts maintain identical electrical specifications across all critical parameters including supply voltage range, input offset voltage, input bias current, quiescent current, propagation delay, and hysteresis characteristics.

The MAX970ESD+T is recommended for new designs and ongoing production due to its active product status. Both parts maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for industrial and commercial applications. The primary consideration is packaging format: the substitute part is supplied in Tape & Reel format, which is standard for automated assembly processes, whereas the original part was supplied in tube format.
