Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP1117YG-13 is determined by the following critical parameters:

• Output configuration (positive adjustable)
• Maximum output current (1A)
• Package type (SOT-89-3 / TO-243AA)
• Input voltage rating compatibility
• Output voltage adjustment range
• Thermal protection capability

The AZ1117CR-ADJTRG1 qualifies as a manufacturer-recommended substitute based on identical output configuration, current rating, and package specification. Both devices maintain positive adjustable output topology with 1A current capacity in the same physical footprint, enabling direct functional replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The AZ1117CR-ADJTRG1 is the designated manufacturer substitute for the obsolete AP1117YG-13. Selection of this alternative is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• Identical output current rating (1A) and adjustable output configuration
• Matching package specification (SOT-89-3 / TO-243AA) for direct PCB compatibility
• Full RoHS3 and REACH compliance alignment
• Improved quiescent current performance (5 mA vs. 10 mA)
• Extended operating temperature range (-20°C to 125°C vs. 0°C to 125°C)
• Superior PSRR specification (70dB vs. 60dB)

The AZ1117CR-ADJTRG1 operates within the same electrical envelope for applications designed around the AP1117YG-13 maximum input voltage of 15V. Applications requiring the full 18V input capability of the original device must verify compatibility with the substitute's 15V maximum input rating.

Frequently Asked Questions (FAQ)

Q: Can the AZ1117CR-ADJTRG1 directly replace the AP1117YG-13 on existing PCBs?

A: Yes. Both devices use identical SOT-89-3 packaging and TO-243AA case specification, enabling direct pin-compatible substitution without PCB modification.

Q: What is the primary difference in input voltage rating between these devices?

A: The AP1117YG-13 accepts maximum input voltage of 18V, while the AZ1117CR-ADJTRG1 is rated to 15V maximum. Applications operating below 15V input voltage are unaffected by this difference.

Q: Are there compliance or regulatory differences between the two parts?

A: Both devices maintain identical RoHS3 and REACH compliance status. No regulatory barriers exist to substitution.

Q: Does the AZ1117CR-ADJTRG1 provide improved performance characteristics?

A: The substitute offers lower quiescent current (5 mA vs. 10 mA), higher PSRR (70dB vs. 60dB), and extended operating temperature range (-20°C to 125°C vs. 0°C to 125°C).

Q: What packaging format is the AZ1117CR-ADJTRG1 supplied in?

A: The AZ1117CR-ADJTRG1 is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: Is the AZ1117CR-ADJTRG1 currently in production?

A: Yes. The AZ1117CR-ADJTRG1 maintains active product status, ensuring continued availability and manufacturing support.
