Key Parameters

Substitute Part Grouping Explanation

The HAL1503 UA qualifies as a direct substitute for the HAL503 UA-A based on the following critical parameters:

• Technology: Both components utilize Hall effect sensing technology
• Output Type: Both feature open-drain output configuration
• Operating Temperature Range: Both support -40°C to 170°C (TJ)
• Temperature Compensation: Both include temperature compensation
• Mounting Type: Both are through-hole mounted
• Package Compatibility: Both use TO-92UA package with TO-226-3, TO-92-3 (TO-226AA) formed leads
• Supply Voltage Compatibility: HAL1503 UA operates at 2.7V ~ 24V, which encompasses the HAL503 UA-A range of 3.8V ~ 24V
• Manufacturer: Both are manufactured by TDK-Micronas GmbH

The HAL1503 UA represents an active product with automotive-grade qualification (AEC-Q100) and superior inventory availability, making it the recommended substitute for obsolete HAL503 UA-A applications.

Parameter Comparison

Engineering Selection Recommendations

The HAL1503 UA is the appropriate substitute for HAL503 UA-A applications. The substitute component maintains identical electrical and mechanical specifications across all critical parameters while offering the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• Automotive-grade qualification and AEC-Q100 certification provide enhanced reliability documentation
• Extended lower supply voltage limit (2.7V vs. 3.8V) offers greater design flexibility
• Significantly higher inventory availability (5222 pcs vs. 784 pcs) reduces procurement lead times

The identical package, pinout, and electrical characteristics enable direct replacement without circuit modification or board redesign.

Frequently Asked Questions (FAQ)

Q: Can HAL1503 UA directly replace HAL503 UA-A in existing designs?

A: Yes. Both components share identical package geometry (TO-92UA), pinout configuration, and electrical operating parameters. Direct substitution is possible without circuit or PCB modifications.

Q: What are the key differences between HAL503 UA-A and HAL1503 UA?

A: The primary differences are product status and supply voltage range. HAL503 UA-A is obsolete with a 3.8V minimum supply voltage, while HAL1503 UA is an active product with automotive qualification and a 2.7V minimum supply voltage. All other electrical and mechanical parameters are identical.

Q: Is the HAL1503 UA suitable for automotive applications?

A: Yes. HAL1503 UA carries automotive-grade designation and AEC-Q100 qualification, making it suitable for automotive and high-reliability applications.

Q: Are there any package or pinout differences?

A: No. Both components use the TO-92UA package with TO-226-3, TO-92-3 (TO-226AA) formed leads. Pinout and mechanical dimensions are identical.

Q: What is the supply voltage compatibility range?

A: HAL1503 UA operates at 2.7V ~ 24V, which fully encompasses the HAL503 UA-A operating range of 3.8V ~ 24V. Designs using HAL503 UA-A at voltages above 3.8V will operate identically with HAL1503 UA.

Q: Does the HAL1503 UA maintain temperature compensation?

A: Yes. Both components include temperature compensation and operate across the identical temperature range of -40°C to 170°C (TJ).
