Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX9042AEUA-T is determined by strict equivalence across the following critical parameters:

• Number of comparator elements: 2
• Output configuration: CMOS, Push-Pull, Rail-to-Rail, TTL
• Supply voltage range: 2.5V ~ 5.5V
• Input offset voltage: 5mV @ 5V
• Input bias current: 1pA @ 5V
• Output current capability: 8mA typical
• Quiescent current: 85µA maximum
• Common-mode rejection ratio: 80dB
• Power supply rejection ratio: 80dB
• Propagation delay: 450ns maximum
• Hysteresis: ±3mV
• Operating temperature range: -40°C ~ 85°C
• Package type: 8-TSSOP/8-MSOP surface mount
• Regulatory compliance: ROHS3, REACH Unaffected

The primary distinction between the main part and its substitute is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The MAX9042AEUA+T is the direct active equivalent of the MAX9042AEUA-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications, operating parameters, and regulatory compliance certifications.

The MAX9042AEUA-T is classified as obsolete, while the MAX9042AEUA+T maintains active product status. For new designs and ongoing production requiring dual comparators with integrated voltage reference in the 8-TSSOP/8-MSOP package, the MAX9042AEUA+T is the appropriate selection.

The packaging difference—tube format for the main part versus tape & reel format for the substitute—reflects standard industry practice for active versus obsolete product lines. Tape & reel packaging is standard for high-volume manufacturing and automated assembly processes.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can MAX9042AEUA+T directly replace MAX9042AEUA-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The MAX9042AEUA+T is the active equivalent and shares all electrical specifications, pin configuration, and package dimensions.

Q: What is the difference between the "-T" and "+T" suffixes?

A: The suffix indicates packaging format. The "-T" denotes tube packaging, while "+T" denotes tape & reel packaging. Both contain identical die and electrical performance.

Q: Why is the MAX9042AEUA-T classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The MAX9042AEUA+T is the active continuation of this product line.
