Number of Elements: The main part contains 2 comparator channels. Direct substitutes must maintain this configuration.
Output Type: CMOS and TTL output compatibility is required for signal interface consistency.
Supply Voltage Range: The 2.7V to 5.5V operating range defines the power supply compatibility window.
Input Offset Voltage: Maximum 1.5mV @ 5V ensures signal fidelity in precision applications.
Input Bias Current: Maximum 15µA @ 5V defines input impedance characteristics.
Quiescent Current: Maximum 9mA establishes power consumption baseline.
Propagation Delay: Maximum 7ns defines timing performance requirements.
Package / Case: 8-SOIC form factor with 0.154" width ensures PCB layout compatibility.
Operating Temperature Range: -40°C to 85°C defines thermal operating envelope.

Substitutes are categorized as follows:

Direct Manufacturer Equivalent: MAX962ESA+T maintains identical electrical specifications and packaging, differing only in product status (Active vs. Obsolete) and packaging format.

Parametric Equivalent: MAX997ESA+T provides compatible electrical performance within the same package but with a single comparator element instead of dual channels.

Manufacturer Recommended Alternatives: TLC3702 series (TLC3702IPWR, TLC3702MDR, TLC3702CPS, TLC3702QPWRQ1) and TS3702IDT offer functional equivalence with extended supply voltage ranges and enhanced specifications, available in multiple package options.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications)

MAX962ESA+T is the primary direct substitute, maintaining all electrical parameters and the 8-SOIC package format. This part is currently in Active product status with higher inventory availability (3650 pcs) compared to the obsolete MAX962ESA-T (943 pcs). Both parts are ROHS3 compliant with MSL 1 rating.

For Extended Supply Voltage Applications

TLC3702MDR and TS3702IDT support extended supply voltage ranges (4V ~ 16V and 2.7V ~ 16V respectively) while maintaining the 8-SOIC package footprint. TLC3702MDR extends the operating temperature range to -55°C ~ 125°C, suitable for industrial and automotive environments. TS3702IDT offers the lowest input bias current (1pA @ 5V) and quiescent current (25µA), beneficial for low-power applications.

For Automotive-Grade Applications

TLC3702QPWRQ1 is qualified to AEC-Q100 automotive standards with -40°C ~ 125°C operating range and MSL 3 rating. This part is available in 8-TSSOP package format.

MAX997ESA+T provides a single comparator element with identical electrical specifications to the MAX962ESA-T, suitable for applications requiring only one comparison channel.

Frequently Asked Questions (FAQ)

Q: Can MAX962ESA+T be used as a direct replacement for MAX962ESA-T?

A: Yes. MAX962ESA+T is electrically and mechanically identical to MAX962ESA-T. Both devices feature dual comparators, 2.7V ~ 5.5V supply range, 8-SOIC package, and identical electrical specifications. The primary difference is product status: MAX962ESA+T is Active while MAX962ESA-T is Obsolete.

Q: What are the key differences between MAX962ESA-T and TLC3702 series parts?

A: TLC3702 series parts operate across an extended supply voltage range (3V ~ 16V or 4V ~ 16V) compared to MAX962ESA-T (2.7V ~ 5.5V). TLC3702 parts feature lower input bias current (5pA vs. 15µA), significantly lower quiescent current (50µA to 90µA vs. 9mA), and higher CMRR (84dB vs. 80dB). However, TLC3702 parts exhibit slower propagation delay (4.5µs vs. 7ns). Package options vary: TLC3702IPWR uses 8-TSSOP, TLC3702MDR uses 8-SOIC (0.154"), and TLC3702CPS uses 8-SOIC (0.209").

Q: Is TS3702IDT compatible with MAX962ESA-T applications?

A: TS3702IDT is functionally compatible for dual-comparator applications. It maintains the 8-SOIC (0.154") package footprint and supports the full 2.7V ~ 5.5V supply range of MAX962ESA-T. TS3702IDT offers superior specifications: lower input bias current (1pA vs. 15µA), lower quiescent current (25µA vs. 9mA), and extended operating temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C). All parts are ROHS3 compliant.

Q: Which substitute part is best for low-power applications?

A: TS3702IDT offers the lowest quiescent current (25µA) and input bias current (1pA), making it optimal for battery-powered or low-power designs. TLC3702 series parts also provide significantly lower quiescent current (50µA to 90µA) compared to MAX962ESA-T (9mA).

Q: Can I use a single-channel comparator (MAX997ESA+T) instead of a dual-channel part?

A: MAX997ESA+T can be used only if your application requires a single comparator channel. It maintains identical electrical specifications to MAX962ESA-T but provides only one comparator element instead of two. Verify that your circuit design does not require both channels before substitution.

Q: What package considerations apply when selecting a substitute?

A: Most substitutes use 8-SOIC packaging with 0.154" width, matching MAX962ESA-T footprint. TLC3702IPWR uses 8-TSSOP (0.173" width) and TLC3702CPS uses 8-SOIC (0.209" width), requiring PCB layout verification. Confirm package dimensions against your PCB design before component selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (MAX962ESA+T, MAX997ESA+T, TLC3702 series, and TS3702IDT) are ROHS3 compliant. All parts carry REACH Unaffected status and EAR99 ECCN classification.

Q: Which substitute supports the widest operating temperature range?

A: TLC3702MDR and TS3702IDT both support -40°C ~ 125°C operating range, compared to MAX962ESA-T (-40°C ~ 85°C). TLC3702MDR is rated for industrial temperature ranges, while TS3702IDT provides this range as standard specification.
