Substitute Part Grouping Explanation

Substitute parts for the AP7333-20SAG-7 are identified based on the following critical parameters that determine functional equivalence:

  • Fixed output voltage of 2V
  • Maximum output current of 300mA
  • Maximum input voltage of 6V
  • Dropout voltage specification of 0.55V @ 300mA
  • Quiescent current of 75 µA
  • PSRR of 65dB (100Hz)
  • Integrated protection features (Over Current, Over Temperature, Short Circuit)
  • Operating temperature range of -40°C ~ 85°C
  • Surface mount packaging in SOT-23-3 configuration
  • Active product status and ROHS3 compliance

The AP7333-20SRG-7 qualifies as a parametric equivalent based on identical electrical specifications and compatible packaging. The primary distinction is the supplier device package designation (SOT23R versus SOT-23-3), which represents a packaging variant of the same physical form factor suitable for equivalent circuit board integration.

Engineering Selection Recommendations

Both the AP7333-20SAG-7 and AP7333-20SRG-7 are active production parts from Diodes Incorporated with identical electrical performance specifications. Selection between these parts should be based on:

  • Inventory availability: AP7333-20SAG-7 has 18,400 pcs in stock; AP7333-20SRG-7 has 691 pcs in stock
  • Supplier device package designation: SAG-7 versus SRG variant
  • Supply chain lead time requirements
  • PCB assembly process compatibility with the specific package variant

Both parts maintain full ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for storage and handling.

Frequently Asked Questions (FAQ)

Q: Can AP7333-20SRG-7 be used as a direct replacement for AP7333-20SAG-7?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage, current rating, dropout voltage, and protection features. The difference in part number suffix (SAG-7 versus SRG-7) reflects packaging variant designation from the supplier, not functional differences.

Q: What is the difference between SOT-23-3 and SOT23R packaging?

A: Both designations refer to the same physical form factor (TO-236-3, SC-59). The variant designation indicates supplier-specific packaging codes. Both are compatible with standard SOT-23-3 PCB footprints.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited). Regulatory and environmental certifications are equivalent.

Q: What are the key parameters that determine substitutability for this linear regulator?

A: The critical parameters are fixed output voltage (2V), maximum output current (300mA), maximum input voltage (6V), dropout voltage (0.55V @ 300mA), quiescent current (75 µA), PSRR (65dB @ 100Hz), integrated protection features, operating temperature range (-40°C ~ 85°C), and surface mount SOT-23-3 packaging.

Q: Can this regulator be used in applications requiring different output voltages?

A: No. The AP7333-20SAG-7 is a fixed-output device rated for 2V output only. Applications requiring different output voltages require alternative regulator part numbers.
