Engineering Selection Recommendations

The MAX6656MEE+ serves as the direct substitute for the obsolete MAX6656MEE. Both components are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications. The primary distinction is product status: the MAX6656MEE is obsolete while the MAX6656MEE+ maintains active production status.

For new designs and ongoing system support, the MAX6656MEE+ is the appropriate selection. Both parts maintain equivalent RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The packaging format, pinout, and functional characteristics remain unchanged between the two variants, enabling direct substitution without circuit modification.
