Substitute Part Grouping Explanation

Substitution eligibility for the MAX5488ETE#G16 is determined by strict equivalence across the following critical parameters:

• Resistance value: 50kΩ
• Circuit count: 2 independent potentiometer circuits
• Tap resolution: 256 taps
• Digital interface: SPI protocol
• Memory configuration: Non-volatile storage
• Supply voltage range: 2.7V to 5.25V
• Package footprint: 16-TQFN (3x3)
• Temperature operating range: -40°C to 85°C

The MAX5488ETE+ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status: the original part is obsolete, while the substitute maintains active production status.

Parameter Comparison

Engineering Selection Recommendations

The MAX5488ETE+ is the appropriate selection for new designs and production continuity. This part maintains full electrical and mechanical compatibility with the original MAX5488ETE#G16 while offering the advantage of active product status from the manufacturer. Active status ensures ongoing availability, technical support, and compliance with current manufacturing standards.

Both parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates minimal moisture sensitivity, reducing handling and storage constraints.

For applications currently utilizing the obsolete MAX5488ETE#G16, direct substitution with MAX5488ETE+ requires no circuit modifications, PCB layout changes, or firmware adjustments due to identical pinout, electrical characteristics, and functional specifications.
