Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI4764-A10-AM is determined by strict alignment across the following critical parameters:

• Frequency coverage: 520kHz ~ 1.71MHz and 64MHz ~ 108MHz
• Modulation protocols: AM, FM, and RDS support
• Receiving current: 130mA
• Supply voltage range: 1.5V ~ 5V
• Operating temperature range: -40°C ~ 85°C
• Package specification: 40-VFQFN Exposed Pad (6x6mm)
• Mounting technology: Surface Mount
• Automotive grade qualification

The SI4769-A20-GM meets all these criteria and qualifies as a direct functional equivalent. The primary distinction is product status: SI4769-A20-GM is active production, whereas SI4764-A10-AM is obsolete.
