Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC862YM8 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 2
• Output Type: Rail-to-Rail
• Package / Case: SOT-23-8
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C to 85°C
• Supply Voltage Compatibility: Minimum 2V, Maximum 5.25V

The MAX4471EKA+T satisfies all mandatory matching criteria. Both devices are housed in identical SOT-23-8 surface-mount packages, feature dual general-purpose rail-to-rail amplifier circuits, and operate within the specified temperature range. The MAX4471EKA+T supports an extended supply voltage range (1.8V to 5.5V), which encompasses the MIC862YM8 operating window, ensuring compatibility in existing circuit designs.

Engineering Selection Recommendations

The MAX4471EKA+T is the designated substitute for the discontinued MIC862YM8. Selection is based on the following engineering factors:

Product Status: The MIC862YM8 is discontinued at DiGi Electronics, while the MAX4471EKA+T maintains active product status with confirmed inventory availability (4350 Pcs New Original In Stock).

Compliance & Certifications: Both devices are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions.

Package & Mounting Compatibility: Identical SOT-23-8 surface-mount packaging ensures direct PCB layout compatibility without redesign requirements.

Functional Equivalence: Both devices provide dual general-purpose rail-to-rail amplifier circuits with matching operating temperature ranges (-40°C to 85°C). The MAX4471EKA+T supply voltage range (1.8V to 5.5V) fully encompasses the MIC862YM8 operating window (2V to 5.25V), ensuring compatibility in all existing applications.

Inventory & Procurement: The MAX4471EKA+T is available in Cut Tape (CT) and Digi-Reel® packaging formats with substantial stock levels, supporting both prototype and production-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the MAX4471EKA+T be used as a direct replacement for the MIC862YM8 without PCB modifications?

A: Yes. Both devices are housed in identical SOT-23-8 surface-mount packages with matching pinout configurations. No PCB layout changes are required for substitution.

Q: Are there differences in electrical performance between the MIC862YM8 and MAX4471EKA+T?

A: The devices differ in several electrical parameters. The MIC862YM8 exhibits higher slew rate (4 V/µs versus 0.002 V/µs), higher gain bandwidth product (3 MHz versus 9 kHz), lower input bias current (20 pA versus 200 pA), and lower input offset voltage (5 mV versus 500 µV). These differences must be evaluated against specific circuit requirements. Both devices maintain identical supply voltage compatibility within the MIC862YM8 operating range.

Q: What is the supply voltage compatibility between these devices?

A: The MIC862YM8 operates from 2V to 5.25V. The MAX4471EKA+T operates from 1.8V to 5.5V. The MAX4471EKA+T supply range fully encompasses the MIC862YM8 range, ensuring compatibility in all existing designs operating within the original specification.

Q: Are both devices RoHS compliant?

A: Yes. Both the MIC862YM8 and MAX4471EKA+T are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging options are available for the MAX4471EKA+T?

A: The MAX4471EKA+T is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both prototype development and high-volume production workflows.

Q: Is the MAX4471EKA+T available in inventory?

A: Yes. The MAX4471EKA+T is an active product with 4350 Pcs New Original In Stock, ensuring immediate availability for procurement.
