Key Parameters

Substitute Part Grouping Explanation

The AZ1117CR-ADJTRG1 qualifies as a direct substitute based on the following alignment criteria:

Compatible Parameters:

• Identical package type: TO-243AA (SOT-89-3) Surface Mount
• Matching output configuration: Positive Adjustable
• Identical minimum output voltage: 1.25V
• Same functional category: Linear Voltage Regulator IC
• Identical regulatory compliance: ROHS3 Compliant, REACH Unaffected

Substitution Logic: The AZ1117CR-ADJTRG1 maintains electrical and mechanical compatibility through shared packaging and adjustable output voltage range. Both devices operate within the same thermal envelope and mounting methodology. The substitute part is classified as Active product status, ensuring continued availability and supply chain reliability compared to the Obsolete AP1115AYG-13.

Engineering Selection Recommendations

Primary Recommendation: AZ1117CR-ADJTRG1

The AZ1117CR-ADJTRG1 is the manufacturer-designated substitute for the obsolete AP1115AYG-13. Selection of this part is supported by:

• Active product status ensuring long-term supply availability
• Identical mechanical compatibility through TO-243AA (SOT-89-3) packaging
• Matching adjustable output voltage minimum of 1.25V
• Enhanced output current capability (1A vs. 600mA) providing design margin
• Improved quiescent current performance (5mA vs. 10mA)
• Superior PSRR specification (70dB vs. 60dB at 120Hz)
• Extended lower operating temperature range (-20°C vs. 0°C)
• Full ROHS3 and REACH compliance alignment

The AZ1117CR-ADJTRG1 is supplied in Tape & Reel packaging format with 1853 units available in current inventory.

Frequently Asked Questions (FAQ)

Q: Can the AZ1117CR-ADJTRG1 directly replace the AP1115AYG-13 in existing designs?

A: Yes. Both devices share identical TO-243AA (SOT-89-3) packaging and positive adjustable output configuration with matching 1.25V minimum output voltage. PCB layout and schematic connections remain unchanged.

Q: What are the key differences between these parts?

A: The AZ1117CR-ADJTRG1 provides higher output current (1A vs. 600mA), lower quiescent current (5mA vs. 10mA), higher maximum output voltage capability (15V vs. 5V), and extended operating temperature range (-20°C to 125°C vs. 0°C to 125°C). The substitute part is Active status versus Obsolete.

Q: Are there any thermal or power dissipation considerations?

A: Both devices operate within the same thermal envelope defined by the TO-243AA package. The AZ1117CR-ADJTRG1's lower quiescent current reduces standby power consumption. Applications requiring the full 1A output capability should verify thermal management against specific load conditions.

Q: Is the packaging format identical?

A: Yes. Both parts use TO-243AA (SOT-89-3) Surface Mount packaging. The AZ1117CR-ADJTRG1 is supplied in Tape & Reel format, which is standard for production environments.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the AP1115AYG-13 and AZ1117CR-ADJTRG1 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the maximum output voltage difference impact?

A: The AP1115AYG-13 maximum output is 5V, while the AZ1117CR-ADJTRG1 reaches 15V. For applications requiring output voltages above 5V, the substitute part provides extended capability. For fixed 5V or lower applications, both parts operate identically within this range.
