Substitute Part Grouping Explanation

Substitution of the MAX966EUA-T is determined by strict equivalence across the following critical parameters:

• Functional Type: Dual-channel general-purpose comparator
• Output Configuration: Open-drain, rail-to-rail output
• Supply Voltage Range: 1.6V ~ 5.5V
• Electrical Performance: Input offset voltage (15mV max @ 5.5V), input bias current (0.05µA max @ 5.5V), quiescent current (10µA max), CMRR/PSRR (56.48dB/80dB), propagation delay (20µs max), hysteresis (±1mV)
• Package Compatibility: 8-TSSOP/8-MSOP surface-mount package with 0.118" (3.00mm) width
• Operating Temperature Range: -40°C ~ 85°C

The MAX966EUA+T meets all substitution criteria through identical electrical specifications and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The MAX966EUA+T is the direct functional equivalent of the MAX966EUA-T. Both devices are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications and package configurations.

The primary distinction between these parts is product status and regulatory compliance. The MAX966EUA-T is classified as obsolete, while the MAX966EUA+T maintains active product status. Additionally, the MAX966EUA+T is ROHS3 compliant, whereas the MAX966EUA-T is RoHS non-compliant. Both devices maintain REACH Unaffected status.

For new designs or ongoing production requiring compliance with current environmental regulations, the MAX966EUA+T is the appropriate selection. The substitute part is available in higher inventory quantities (6200 Pcs vs. 2800 Pcs) and is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both prototype and production-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the MAX966EUA+T directly replace the MAX966EUA-T in existing designs?

A: Yes. The MAX966EUA+T is electrically and mechanically identical to the MAX966EUA-T. All electrical parameters, including supply voltage range, input offset voltage, bias current, quiescent current, CMRR, PSRR, propagation delay, and hysteresis specifications are equivalent. Both devices use the same 8-TSSOP/8-MSOP surface-mount package. No circuit modifications are required for substitution.

Q: What is the difference between the MAX966EUA-T and MAX966EUA+T part numbers?

A: The suffix designations (-T vs. +T) indicate different packaging and product status classifications. The MAX966EUA-T is obsolete and RoHS non-compliant. The MAX966EUA+T is an active product with ROHS3 compliance and is supplied in Cut Tape (CT) and Digi-Reel® formats. The electrical specifications and package dimensions are identical.

Q: Are there any pin configuration differences between these parts?

A: No. Both the MAX966EUA-T and MAX966EUA+T use the 8-pin TSSOP/MSOP package with identical pinout and electrical function. PCB layout and schematic connections require no modification.

Q: What is the moisture sensitivity level for these comparators?

A: Both devices have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture-related degradation concerns. Standard handling and storage practices are sufficient.

Q: Why should I select the MAX966EUA+T over the MAX966EUA-T?

A: The MAX966EUA+T is the recommended selection for new designs and ongoing production. It maintains active product status, ensuring long-term availability and supply chain stability. ROHS3 compliance satisfies current environmental regulations and procurement requirements. Higher inventory availability (6200 Pcs) supports both prototype development and production-volume orders.
