Substitute Part Grouping Explanation

Substitute parts for the AP7315-12FS4-7B are identified based on strict electrical and mechanical parameter matching. The substitution criteria include:

  • Identical output voltage specification (1.2V fixed)
  • Matching output current rating (150mA)
  • Equivalent maximum input voltage (5.25V)
  • Same dropout voltage performance (0.64V @ 150mA)
  • Identical package configuration (4-XDFN Exposed Pad, X2-DFN1010-4)
  • Matching operating temperature range (-40°C ~ 85°C)
  • Equivalent PSRR performance (75dB at 1kHz)
  • Identical protection features (Over Current)
  • Same regulatory compliance (ROHS3, REACH Unaffected)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes within the AP7315 base product family.
