Substitute Part Grouping Explanation

Substitution of the MAX2623EUA-T is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:

  • Identical frequency range (885–950 MHz) and center frequency (917.5 MHz)
  • Matching supply voltage specification (2.7V–5.5V)
  • Identical tuning voltage range (0.4V–2.4V)
  • Equivalent output power (−3 ±3 dBm)
  • Matching 2nd harmonic suppression (−27 dBc Typ)
  • Same maximum supply current (11.5 mA)
  • Identical pushing factor (0.28 MHz/V Typ)
  • Compatible operating temperature range (−40°C to +85°C)
  • Compatible package type (8-TSSOP/8-MSOP, 3.00 mm width)
  • Equivalent RoHS and MSL compliance

The MAX2623EUA+T meets all substitution criteria and represents a direct functional equivalent with identical electrical performance and mechanical compatibility.

Engineering Selection Recommendations

The MAX2623EUA+T is the direct substitute for the obsolete MAX2623EUA-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications and mechanical compatibility. The primary distinction is product status: the MAX2623EUA-T is obsolete, while the MAX2623EUA+T maintains active production status.

The MAX2623EUA+T is supplied in Tape & Reel (TR) packaging format, whereas the main part uses tube packaging. This difference affects handling and assembly processes but does not impact electrical performance or functional compatibility. Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring equivalent environmental and regulatory compliance.

For new designs or production continuity of existing systems, the MAX2623EUA+T is the appropriate selection due to its active product status and guaranteed long-term availability.
