AP1117Y50G-13 Equivalent & Substitute Parts

Part Overview

The AP1117Y50G-13 is a linear voltage regulator IC from Diodes Incorporated designed for positive fixed 5V output at 1A current capacity in a SOT-89-3 surface mount package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part operates across an input voltage range up to 18V with a maximum dropout voltage of 1.4V at full load, incorporating over-current and over-temperature protection features.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP1117Y50G-13 is determined by the following critical parameters:

• Fixed output voltage of 5V
• Output current capability of 1A minimum
• Surface mount package compatibility (SOT-89-3 / TO-243AA)
• Input voltage tolerance (minimum 15V acceptable for most applications)
• Protection features (thermal management required)
• RoHS3 compliance and REACH unaffected status

The AZ1117CR-5.0TRG1 qualifies as a direct substitute based on matching output voltage, current rating, package type, and regulatory compliance. Both parts are manufactured by Diodes Incorporated and share the same base product architecture (AP1117 / AZ1117 series).

Parameter Comparison

Engineering Selection Recommendations

The AZ1117CR-5.0TRG1 is the qualified substitute for the obsolete AP1117Y50G-13. Selection is supported by:

• Active product status ensuring long-term availability and manufacturing support
• Identical output voltage and current specifications
• Matching SOT-89-3 package footprint for direct PCB compatibility
• ROHS3 compliance and REACH unaffected status maintaining regulatory alignment
• Extended operating temperature range (-20°C to 125°C) providing broader environmental tolerance
• Improved quiescent current performance (6 mA vs. 10 mA) and superior PSRR characteristics

The maximum input voltage specification of 15V on the substitute part is suitable for applications where the main part's 18V rating is not required. Designs operating at input voltages exceeding 15V require evaluation of alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the AZ1117CR-5.0TRG1 be used as a direct replacement on existing PCBs designed for the AP1117Y50G-13?

A: Yes. Both parts use the TO-243AA (SOT-89-3) package with identical pinout and footprint. No PCB modifications are required for physical substitution.

Q: What is the difference in input voltage handling between these parts?

A: The AP1117Y50G-13 accepts input voltages up to 18V, while the AZ1117CR-5.0TRG1 is rated to 15V maximum. Applications requiring input voltages between 15V and 18V must verify circuit operation or select alternative components.

Q: Are there differences in thermal protection between these regulators?

A: The AP1117Y50G-13 includes over-current and over-temperature protection. The AZ1117CR-5.0TRG1 provides thermal shutdown protection. Both offer thermal management; specific protection behavior may differ and should be verified against application requirements.

Q: Does the substitute part meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status.

Q: What is the significance of the AZ1117CR-5.0TRG1 being in active product status?

A: Active status indicates ongoing manufacturing and availability from Diodes Incorporated, ensuring supply chain continuity and technical support compared to the obsolete AP1117Y50G-13.

Q: Is the tape and reel packaging of the substitute compatible with automated assembly?

A: Yes. Tape & Reel (TR) packaging is standard for automated pick-and-place assembly processes and is compatible with standard component feeders.
