HAL516UA-A Equivalent & Substitute Parts

Part Overview

The HAL516UA-A is a unipolar magnetic switch utilizing Hall Effect technology, manufactured by TDK-Micronas GmbH. This component operates as a digital switch with open drain output, designed for magnetic field detection applications. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. Substitute parts must maintain compatibility across electrical performance, output characteristics, and thermal operating ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HAL516UA-A are qualified based on the following criteria:

Core Functional Requirements:

• Unipolar switch function with Hall Effect technology
• South pole polarization
• Open drain output configuration
• Supply voltage range compatibility (minimum 3.8V operation required)
• Operating temperature range support (-40°C minimum, 170°C maximum preferred)

Electrical Compatibility:

• Output type must be open drain
• Supply current and output current specifications must support the application requirements
• Sensing range parameters (trip and release thresholds) must be evaluated for application-specific magnetic field detection needs

Physical Compatibility:

• Through hole mounting preferred for direct replacement; surface mount alternatives require PCB redesign
• Package form factor determines mechanical fit and lead configuration

Engineering Selection Recommendations

HAL1509 SU-A (TDK-Micronas GmbH)

This substitute is an active product from the same manufacturer, ensuring design continuity and technical support availability. The HAL1509 SU-A maintains identical core functionality (unipolar switch, Hall Effect, south pole, open drain) and operating temperature range (-40°C to 170°C). The extended lower voltage supply limit (2.7V vs. 3.8V) provides additional operational flexibility. However, this part requires surface mount PCB integration, necessitating circuit board redesign for direct replacement. The sensing range differs (3.7mT trip, 5.5mT release), requiring application-level validation to confirm magnetic field detection compatibility.

MLX92241LUA-AAA-007-BU (Melexis Technologies NV)

This substitute maintains through-hole mounting compatibility with the original HAL516UA-A, eliminating PCB redesign requirements. The part preserves core functionality and extends the lower voltage supply limit to 2.7V. The operating temperature range reaches -40°C to 150°C, which is 20°C lower than the original specification. The sensing range differs significantly (7.1mT trip, 2mT release), requiring application-level validation. This part is an active product with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory compliance.

Selection Criteria:

• For applications requiring minimal PCB modification and identical thermal performance: MLX92241LUA-AAA-007-BU
• For applications where surface mount integration is feasible and same-manufacturer support is prioritized: HAL1509 SU-A
• For applications with magnetic field detection thresholds below 3.7mT: evaluate MLX92241LUA-AAA-007-BU (2mT release threshold)
• For applications with magnetic field detection thresholds above 7.1mT: evaluate HAL1509 SU-A (5.5mT release threshold)

Frequently Asked Questions (FAQ)

Q: Can HAL1509 SU-A directly replace HAL516UA-A without PCB modification?

A: No. The HAL1509 SU-A uses SOT-23-3 surface mount packaging, while the HAL516UA-A uses TO-92-3 through-hole packaging. Direct mechanical replacement is not possible without PCB redesign and rework.

Q: Can MLX92241LUA-AAA-007-BU directly replace HAL516UA-A?

A: Yes, mechanically. Both use TO-92-3 through-hole packaging with identical lead configuration. However, the sensing range differs (7.1mT trip vs. 5mT trip), requiring validation that the application's magnetic field detection thresholds remain compatible.

Q: What is the impact of different sensing ranges on system operation?

A: Sensing range determines the magnetic field strength at which the switch activates (trip) and deactivates (release). If the application's magnetic field strength falls outside the substitute part's sensing range, the switch will not function as intended. Application-level testing is necessary to confirm compatibility.

Q: Are both substitute parts RoHS compliant?

A: Yes. HAL1509 SU-A and MLX92241LUA-AAA-007-BU are both ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the difference between TJ and TA temperature specifications?

A: TJ refers to junction temperature (internal die temperature), while TA refers to ambient temperature (surrounding environment). HAL516UA-A and HAL1509 SU-A specify TJ (-40°C to 170°C), while MLX92241LUA-AAA-007-BU specifies TA (-40°C to 150°C). Applications operating at elevated ambient temperatures should account for this distinction.

Q: Can I use HAL1509 SU-A in applications requiring 3.8V minimum supply voltage?

A: Yes. HAL1509 SU-A supports 2.7V to 24V supply range, which includes the 3.8V minimum requirement of the original HAL516UA-A.

Q: Which substitute part has better long-term availability?

A: Both HAL1509 SU-A and MLX92241LUA-AAA-007-BU are active products with current inventory levels (14,235 pcs and 980 pcs respectively), indicating established supply chains and ongoing manufacturing support.
