AP1117Y15G-13 Equivalent & Substitute Parts

Part Overview

The AP1117Y15G-13 is a linear voltage regulator IC from Diodes Incorporated designed for positive fixed output applications. It delivers 1A output current at a fixed 1.5V output voltage in a surface-mount SOT-89-3 package. The device is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity. The AP1117Y15G-13 incorporates over-current and over-temperature protection features, operating across a 0°C to 125°C temperature range with a maximum input voltage of 18V and a dropout voltage of 1.4V at full load.

Key Parameters

Substitute Part Grouping Explanation

The AZ1117CR-1.5TRG1 qualifies as a direct substitute for the AP1117Y15G-13 based on the following critical parameters:

• Fixed output voltage of 1.5V matches exactly
• Output current rating of 1A is identical
• Package and case designation (TO-243AA / SOT-89-3) are the same
• Surface-mount mounting type is consistent
• Both devices are manufactured by Diodes Incorporated
• RoHS3 compliance and REACH unaffected status align
• Both operate within compatible temperature ranges

The AZ1117CR-1.5TRG1 represents an active product status alternative, addressing the obsolescence of the original AP1117Y15G-13. The substitute maintains functional equivalence for 1.5V / 1A linear regulation applications.

Parameter Comparison

Engineering Selection Recommendations

The AZ1117CR-1.5TRG1 is the designated manufacturer substitute for the obsolete AP1117Y15G-13. Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and production transitions.

The substitute exhibits improved specifications in several areas: lower quiescent current (6 mA vs. 10 mA), higher PSRR (70dB vs. 60dB), and an extended lower operating temperature limit (-20°C vs. 0°C). The AZ1117CR-1.5TRG1 operates at a reduced maximum input voltage of 15V compared to the original 18V specification; this difference must be evaluated against your specific input voltage requirements.

The AZ1117CR-1.5TRG1 is supplied in Tape & Reel format, suitable for automated assembly processes. Both devices share identical package geometry and pinout, enabling direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the AZ1117CR-1.5TRG1 replace the AP1117Y15G-13 in existing designs?

A: Yes. Both devices share identical output voltage (1.5V), output current (1A), package type (TO-243AA / SOT-89-3), and pinout. Direct substitution is possible provided your input voltage does not exceed 15V.

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

A: The AP1117Y15G-13 accepts input voltages up to 18V, while the AZ1117CR-1.5TRG1 is rated to 15V maximum. If your application requires input voltages between 15V and 18V, the substitute is not suitable without circuit redesign.

Q: Are there differences in protection features?

A: The original part includes over-current and over-temperature protection. The substitute specifies thermal shutdown protection. Both provide thermal management; verify that thermal shutdown behavior meets your application requirements.

Q: Does the lower quiescent current of the AZ1117CR-1.5TRG1 affect compatibility?

A: No. Lower quiescent current (6 mA vs. 10 mA) is a performance improvement that reduces standby power consumption. This change is backward-compatible and beneficial for battery-powered or low-power applications.

Q: What packaging format differences exist?

A: The AP1117Y15G-13 is supplied in bulk packaging. The AZ1117CR-1.5TRG1 is supplied in Tape & Reel format, optimized for automated pick-and-place assembly. Both contain identical die and package geometry.

Q: Are both parts RoHS compliant?

A: Yes. Both the AP1117Y15G-13 and AZ1117CR-1.5TRG1 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
