Substitute Part Grouping Explanation

Substitution eligibility for the MAX9989ETP is determined by strict alignment across the following critical parameters:

• Functional Classification: LO buffer IC for RF applications
• Frequency Specification: 700MHz to 1.1GHz operating range
• RF Application Domain: Cellular and GSM compatibility
• Reverse Isolation Performance: 40dB minimum
• Physical Package: 20-TQFN (5x5) with exposed pad
• Surface Mount Compatibility: Identical mounting technology
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The MAX9989ETP+ meets all substitution criteria as a direct equivalent, sharing identical electrical specifications, package geometry, and compliance certifications while maintaining active product status.

Parameter Comparison

Engineering Selection Recommendations

The MAX9989ETP+ is a direct substitute for the MAX9989ETP. Both components are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications. The primary distinction is product status: the MAX9989ETP is obsolete while the MAX9989ETP+ maintains active production status.
