Substitute Part Grouping Explanation

Substitution eligibility for the LMK61E2BAA-SIAT is determined by strict alignment of the following critical parameters:

• Frequency capability: 400MHz, 900MHz, 1GHz operation
• Supply voltage range: 3.135V ~ 3.465V
• Supply current: 162 mA
• Operating temperature range: -40°C ~ 85°C
• Physical package: 8-QFM (7x5) form factor
• Mounting technology: Surface Mount
• Moisture sensitivity classification: MSL 3
• Regulatory compliance: RoHS3 and REACH status

The LMK61E2BBA-SIAT meets all specified parameters and qualifies as a parametric equivalent. Both devices share the same base product number (LMK61E2), indicating common design lineage and functional compatibility.
