AP1117ID50G-13 Equivalent & Substitute Parts

Part Overview

The AP1117ID50G-13 is a linear voltage regulator IC from Diodes Incorporated designed to provide a fixed 5V output at 1A maximum current. This Surface Mount device in TO-252-3 (DPAK) packaging is classified as Obsolete, making identification of suitable substitute components essential for ongoing production and maintenance applications. The part's discontinuation necessitates evaluation of functionally equivalent alternatives that maintain electrical and mechanical compatibility within system designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP1117ID50G-13 is determined by strict alignment of the following electrical and mechanical parameters:

• Fixed output voltage of 5V
• Output current capability of 1A minimum
• Maximum input voltage rating of 15V or higher
• TO-252-3 package compatibility (Surface Mount DPAK)
• Operating temperature range of -40°C to 125°C or wider
• Protection features including thermal management

The AZ1117D-5.0TRE1 qualifies as a direct substitute based on these criteria. Both devices share identical output voltage and current specifications, compatible packaging, and overlapping thermal operating ranges. Electrical parameter variations (dropout voltage, PSRR, quiescent current) remain within acceptable tolerances for typical linear regulator applications.

Engineering Selection Recommendations

The AZ1117D-5.0TRE1 serves as the primary substitute for the obsolete AP1117ID50G-13. Both components are manufactured by Diodes Incorporated and maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for existing designs.

Key considerations for selection:

• Input voltage rating: The AZ1117D-5.0TRE1 specifies a maximum input voltage of 15V compared to 18V for the AP1117ID50G-13. Verify that system input voltage does not exceed 15V.
• Dropout voltage: The substitute exhibits lower dropout voltage (1.25V vs 1.4V), providing improved efficiency in power-constrained applications.
• PSRR performance: The AZ1117D-5.0TRE1 offers superior power supply rejection ratio (75dB vs 60dB), beneficial for noise-sensitive circuits.
• Packaging: Identical TO-252-3 DPAK footprint ensures direct PCB compatibility without layout modifications.
• Product status: The substitute is classified as "Not For New Designs," indicating limited long-term availability. For new development, evaluation of actively produced alternatives is recommended.

Frequently Asked Questions (FAQ)

Q: Can the AZ1117D-5.0TRE1 be used as a direct replacement on existing PCBs designed for the AP1117ID50G-13?

A: Yes. Both devices use identical TO-252-3 DPAK packaging with the same pinout and footprint. No PCB modifications are required for mechanical or electrical compatibility.

Q: What is the primary difference between these two parts?

A: The main difference is input voltage rating: AP1117ID50G-13 accepts up to 18V input, while AZ1117D-5.0TRE1 is rated to 15V maximum. The substitute also provides lower dropout voltage and higher PSRR. Verify your system input voltage does not exceed 15V before substitution.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No regulatory barriers exist for substitution in existing designs.

Q: Why is the AZ1117D-5.0TRE1 marked "Not For New Designs"?

A: This designation indicates the part is in declining availability and should not be selected for new product development. For new designs, consult the substitute part list provided for the AZ1117D-5.0TRE1 to identify actively produced alternatives.

Q: Does the lower dropout voltage of the substitute affect circuit operation?

A: Lower dropout voltage (1.25V vs 1.4V) is advantageous, requiring less input-to-output voltage differential to maintain regulation. This improves efficiency and reduces heat dissipation. No negative effects on circuit operation result from this improvement.

Q: What packaging format is the AZ1117D-5.0TRE1 supplied in?

A: The AZ1117D-5.0TRE1 is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The AP1117ID50G-13 packaging format was not specified in the original documentation.
