AP1117ID33G-13 Equivalent & Substitute Parts

Part Overview

The AP1117ID33G-13 is a linear voltage regulator IC from Diodes Incorporated designed to provide a fixed 3.3V output at 1A maximum current. This device operates as a positive fixed output regulator in a TO-252-3 surface mount package. The part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP1117ID33G-13 is determined by the following critical parameters:

• Output Voltage: Must be fixed at 3.3V
• Output Current Capability: Must support 1A minimum
• Package Type: Must be TO-252-3 (DPAK with 2 Leads + Tab)
• Mounting Type: Must be Surface Mount
• Operating Temperature Range: Must cover -40°C ~ 125°C (TJ)
• Regulatory Compliance: Must maintain ROHS3 compliance

The AZ1117D-3.3TRE1 meets all substitution criteria as an active product from the same manufacturer with identical output specifications and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The AZ1117D-3.3TRE1 is the direct substitute for the obsolete AP1117ID33G-13. Both parts are manufactured by Diodes Incorporated and maintain identical output voltage and current specifications. The substitute part offers improved performance characteristics: lower maximum dropout voltage (1.25V versus 1.4V) and higher PSRR (75dB versus 60dB). The maximum input voltage specification is reduced from 18V to 15V; applications requiring input voltages above 15V must retain the original AP1117ID33G-13 or select an alternative regulator.

Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating, and identical operating temperature ranges, ensuring regulatory and environmental compatibility. The AZ1117D-3.3TRE1 is available in active production status with significantly higher inventory availability (174,050 units versus 729 units).

Frequently Asked Questions (FAQ)

Q: Can the AZ1117D-3.3TRE1 directly replace the AP1117ID33G-13 in all applications?

A: Direct replacement is valid for applications with input voltages up to 15V. If your design requires input voltages between 15V and 18V, the original AP1117ID33G-13 specifications must be maintained or an alternative regulator selected.

Q: What are the key differences between these two parts?

A: Both parts provide identical 3.3V, 1A output in the same TO-252-3 package. The AZ1117D-3.3TRE1 features lower dropout voltage (1.25V versus 1.4V) and higher power supply rejection ratio (75dB versus 60dB). The maximum input voltage differs: 15V for the substitute versus 18V for the original.

Q: Are the packages physically identical?

A: Yes. Both parts use the TO-252-3 package (DPAK with 2 Leads + Tab, SC-63 designation). PCB footprints and thermal characteristics are equivalent.

Q: What is the availability status of each part?

A: The AP1117ID33G-13 is obsolete with limited remaining inventory (729 units). The AZ1117D-3.3TRE1 is in active production with substantial inventory (174,050 units).

Q: Do both parts meet current regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1, Unlimited).
