Substitute Part Grouping Explanation

Substitution for the AP7361C-33SPR-13 is determined by equivalence across the following critical parameters:

  • Output voltage specification (3.3V fixed)
  • Output current capability (1A)
  • Maximum input voltage rating (6V)
  • Dropout voltage performance (0.36V @ 1A typical)
  • Quiescent current (80 µA)
  • PSRR characteristics (75dB ~ 55dB across 1kHz ~ 10kHz)
  • Package type and pin configuration (8-SOIC with exposed pad)
  • Operating temperature range (-40°C ~ 85°C)
  • Protection features (Over Current, Over Temperature)
  • Control features (Enable function)

The AP7361C-33SP-13 meets all these criteria and is classified as a parametric equivalent.

Engineering Selection Recommendations

Both the AP7361C-33SPR-13 and AP7361C-33SP-13 are active products from Diodes Incorporated with identical electrical specifications and package configurations. Selection between these parts is based on packaging format: the AP7361C-33SPR-13 is supplied in Tape & Reel format, while the AP7361C-33SP-13 is also supplied in Tape & Reel format. Both devices maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The choice between these equivalents depends on procurement requirements, inventory availability, and supply chain considerations rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can AP7361C-33SP-13 be used as a direct replacement for AP7361C-33SPR-13?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, output voltage, current rating, dropout voltage, quiescent current, PSRR, package type, operating temperature range, and protection features. The parts differ only in packaging format designation.

Q: What determines if a part is a valid substitute for the AP7361C-33SPR-13?

A: A valid substitute must match the following specifications: 3.3V fixed output voltage, 1A output current, 6V maximum input voltage, 0.36V maximum dropout voltage at 1A, 80 µA quiescent current, 75dB ~ 55dB PSRR across 1kHz ~ 10kHz, 8-SOIC package with exposed pad, -40°C to 85°C operating range, and identical protection and control features.

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

A: No. Both parts carry identical RoHS3 compliance, MSL 1 rating, and REACH unaffected status.

Q: What is the significance of the packaging designation difference (SPR vs SP)?

A: Both designations indicate Tape & Reel packaging. The parts are functionally and electrically identical; the designation difference reflects supplier or internal classification only.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts use the same 8-SOIC package with exposed pad, identical pin configuration, and matching thermal characteristics, allowing direct substitution in assembly processes.
