AP432AYG-13 Equivalent & Substitute Parts
Part Overview
The AP432AYG-13 is a shunt voltage reference IC manufactured by Diodes Incorporated, designed for precision voltage regulation applications in power management circuits. This adjustable reference provides a fixed output of 1.24V with a maximum output voltage of 20V and supports output currents up to 200mA. The device is packaged in SOT-89-3 surface mount configuration.
The AP432AYG-13 is classified as obsolete. Identifying suitable substitute components is necessary to maintain design continuity and ensure availability for new production runs or system updates.

Substitute Part Grouping Explanation
Substitution of the AP432AYG-13 is determined by the following critical parameters:
- Reference Type: Shunt voltage reference architecture
- Output Type: Adjustable output configuration
- Voltage - Output (Min/Fixed): 1.24V fixed reference point
- Voltage - Output (Max): Maximum output voltage capability
- Current - Output: Maximum output current rating
- Tolerance: Voltage accuracy specification (±0.5%)
- Package / Case: TO-243AA physical form factor
- Supplier Device Package: SOT-89-3 pin configuration
- RoHS and REACH Compliance: Environmental and regulatory requirements
The AZ431LARTR-G1 qualifies as a substitute based on matching reference type, output type, fixed voltage point, tolerance specification, package form factor, and compliance certifications. Differences in maximum output voltage (18V vs 20V), output current (100mA vs 200mA), temperature coefficient, cathode current, and operating temperature range must be evaluated against specific application requirements.

Engineering Selection Recommendations
The AZ431LARTR-G1 is the manufacturer-recommended substitute for the obsolete AP432AYG-13. Both components are manufactured by Diodes Incorporated and maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected).
The AZ431LARTR-G1 offers the advantage of active product status with higher inventory availability (35,300 pcs in stock versus 2,600 pcs for the AP432AYG-13). The substitute maintains the same reference architecture, output type, fixed voltage point, tolerance specification, and physical package configuration.
Design integration requires verification that application requirements accommodate the AZ431LARTR-G1 parameter differences: maximum output voltage of 18V (versus 20V), maximum output current of 100mA (versus 200mA), lower cathode current of 80µA (versus 300µA), and extended operating temperature range of -40°C to 125°C (versus -20°C to 85°C).
Frequently Asked Questions (FAQ)
Q: Can the AZ431LARTR-G1 directly replace the AP432AYG-13 in existing designs?
A: Direct replacement is possible if the application operates within the AZ431LARTR-G1 parameter specifications. The lower maximum output voltage (18V) and output current (100mA) must not exceed circuit requirements. Verify that your design does not demand the full 20V or 200mA capabilities of the original part.
Q: What are the key differences between these two parts?
A: The primary differences are maximum output voltage (20V vs 18V), maximum output current (200mA vs 100mA), temperature coefficient (30ppm/°C vs 20ppm/°C), cathode current (300µA vs 80µA), and operating temperature range (-20°C to 85°C vs -40°C to 125°C). Both maintain identical reference voltage (1.24V), tolerance (±0.5%), and package configuration (SOT-89-3).
Q: Are both parts in the same physical package?
A: Yes. Both the AP432AYG-13 and AZ431LARTR-G1 use the TO-243AA package with SOT-89-3 pin configuration, enabling direct physical substitution on printed circuit boards.
Q: Why is the AP432AYG-13 marked as obsolete?
A: The AP432AYG-13 has reached end-of-life status. The AZ431LARTR-G1 represents the active product line continuation from Diodes Incorporated for this reference voltage IC category.
Q: Does the AZ431LARTR-G1 meet the same compliance requirements?
A: Yes. Both components are ROHS3 Compliant and REACH Unaffected, maintaining identical environmental and regulatory compliance certifications.
