The substitute part identified meets all these criteria, differing only in physical color designation and current product availability status.

Parameter Comparison

Engineering Selection Recommendations

The Adafruit 5447 serves as a direct functional equivalent to the discontinued Adafruit 1569. Both adapters provide identical electrical and mechanical conversion from microSD™ to SD format with matching regulatory compliance profiles. The primary distinction is product status: the 5447 maintains active availability while the 1569 is discontinued at DiGi Electronics.

Selection of the 5447 is supported by:

• Identical connector conversion specification
• Matching ROHS3 compliance certification
• Equivalent tariff and export classification
• Higher current inventory availability (1116 units versus 1033 units)
