Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX1271BEAI is determined by strict equivalence across the following critical parameters:

• Number of Channels: 8 channels
• Resolution: 12 bits
• Sampling Rate: 110 kHz
• Data Interface: Serial
• Voltage Supply Source: Single Supply
• Operating Temperature Range: -40°C to 85°C
• Package / Case: 28-SSOP (0.209", 5.30mm Width)

The MAX1271BEAI+ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The MAX1271BEAI+ is the direct substitute for the obsolete MAX1271BEAI. Both devices share identical functional specifications: 8-channel, 12-bit resolution, 110 kHz sampling rate, serial interface, and 28-SSOP package footprint.

The MAX1271BEAI+ offers the following advantages:

• Active product status ensures continued availability and manufacturer support
• ROHS3 compliance meets current environmental and regulatory requirements
• Tube packaging provides standard handling and storage conditions
• Specified supply voltage range (4.75V to 5.25V) provides explicit electrical parameters

For applications requiring RoHS non-compliant components or legacy system maintenance, the MAX1271BEAI remains available in limited inventory. For new designs and systems requiring regulatory compliance, the MAX1271BEAI+ is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the MAX1271BEAI+ directly replace the MAX1271BEAI in existing designs?

A: Yes. Both devices are electrically and mechanically equivalent. The MAX1271BEAI+ maintains identical channel count (8), resolution (12 bits), sampling rate (110 kHz), serial interface, and 28-SSOP package dimensions. PCB layout and firmware integration require no modification.

Q: What is the significance of the "+" suffix in MAX1271BEAI+?

A: The "+" designation indicates an updated product variant with enhanced compliance status. The MAX1271BEAI+ is ROHS3 compliant and carries active product status, whereas the MAX1271BEAI is obsolete and RoHS non-compliant.

Q: Are there differences in supply voltage specifications between the two parts?

A: The MAX1271BEAI+ specifies a supply voltage range of 4.75V to 5.25V. The MAX1271BEAI does not provide explicit voltage specifications in available documentation. Both operate as single-supply devices within the -40°C to 85°C temperature range.

Q: What packaging options are available for the MAX1271BEAI+?

A: The MAX1271BEAI+ is supplied in Tube packaging. The original MAX1271BEAI packaging format is not specified in current documentation.

Q: Is the 28-SSOP package footprint identical between both parts?

A: Yes. Both the MAX1271BEAI and MAX1271BEAI+ use the 28-SSOP package with 0.209" width and 5.30mm pitch. No PCB layout modifications are required for substitution.
