Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP1117D15G-13 are identified based on the following critical parameters that determine functional compatibility:

• Fixed output voltage of 1.5V
• Output current capability of 1A
• Maximum input voltage tolerance (18V or higher)
• Voltage dropout characteristics at rated current
• TO-252-3 package compatibility
• Surface mount mounting type
• Positive output configuration
• Protection features (Over Current, Over Temperature, or Thermal Shutdown)

The substitute parts listed below maintain these core electrical and mechanical specifications, ensuring direct functional replacement capability in existing circuit designs.

Engineering Selection Recommendations

AZ1117CD-1.5TRG1 is the recommended substitute for new designs and ongoing production. This part is currently in active product status, ensuring long-term availability and supply chain stability. It maintains the same fixed 1.5V output, 1A current capability, and TO-252-3 package as the original AP1117D15G-13. The AZ1117CD-1.5TRG1 features improved quiescent current performance (6 mA versus 10 mA) and enhanced PSRR (70dB versus 60dB), providing superior power supply rejection. The maximum input voltage is rated at 15V, which is lower than the original 18V specification; applications requiring input voltages above 15V must use AP1117D15L-13 instead. All parts are ROHS3 compliant and carry identical regulatory certifications (REACH Unaffected, EAR99).

AP1117D15L-13 is a parametric equivalent suitable for applications requiring the full 18V input voltage rating. This part maintains identical electrical specifications to the original AP1117D15G-13, including quiescent current, PSRR, and dropout voltage characteristics. However, AP1117D15L-13 is also listed as obsolete, making it a secondary choice for new production. This part is appropriate only when the 18V input voltage capability is a mandatory design requirement.

Frequently Asked Questions (FAQ)

Q: Can AZ1117CD-1.5TRG1 replace AP1117D15G-13 in all applications?

A: AZ1117CD-1.5TRG1 is compatible with applications where the input voltage does not exceed 15V. If your circuit requires input voltages between 15V and 18V, use AP1117D15L-13 instead. Both parts deliver identical 1.5V output at 1A and use the same TO-252-3 package.

Q: What is the difference between the packaging options listed?

A: AP1117D15G-13 is supplied in Tape & Reel (TR) packaging. AP1117D15L-13 is supplied in Cut Tape (CT) packaging. Both use the same TO-252-3 component package. Packaging format affects handling and assembly processes but does not impact electrical performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. AP1117D15G-13, AZ1117CD-1.5TRG1, and AP1117D15L-13 are all ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH Unaffected status.

Q: Why is AZ1117CD-1.5TRG1 recommended over AP1117D15L-13?

A: AZ1117CD-1.5TRG1 is in active product status, ensuring continued availability and supply chain support. AP1117D15L-13 is obsolete. For new designs and production, active parts are preferred to avoid future obsolescence issues.

Q: What are the key electrical differences between these parts?

A: The primary differences are input voltage rating (AZ1117CD-1.5TRG1 at 15V maximum versus AP1117D15G-13 and AP1117D15L-13 at 18V maximum) and quiescent current (AZ1117CD-1.5TRG1 at 6 mA versus 10 mA for the others). Output voltage, current rating, and package remain identical across all three parts.
