HAL108JQ-I Equivalent & Substitute Parts

Part Overview

The HAL108JQ-I is a unipolar Hall effect magnetic switch manufactured by TDK-Micronas GmbH in TO-92UA-6 through-hole packaging. This digital switch operates with open drain output and is designed for magnetic field detection applications requiring South Pole polarization. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system support and new design implementations. Substitute parts maintain core functional compatibility while offering improved availability and extended product lifecycles.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HAL108JQ-I are qualified based on the following criteria:

Core Functional Requirements:

• Unipolar switch function with Hall effect technology
• South Pole polarization matching
• Open drain output configuration
• Supply voltage compatibility within 3.8V ~ 24V range

Electrical Compatibility:

• Sensing range parameters (trip and release thresholds) must fall within acceptable operational margins for the application
• Output current capability must support connected load requirements
• Temperature operating range must encompass the primary application environment

Physical & Compliance Requirements:

• RoHS compliance status (RoHS3 acceptable for RoHS Compliant products)
• Moisture sensitivity level MSL 1 (Unlimited)
• ECCN and HTSUS classifications matching for regulatory consistency

Substitute parts may differ in mounting type (surface mount vs. through hole), packaging format, and specific sensing thresholds while maintaining functional equivalence for unipolar Hall switch applications.

Engineering Selection Recommendations

HAL1506SU-A is recommended for new surface mount designs requiring active product status and extended lower temperature operation. This part maintains TDK-Micronas manufacturing continuity and ROHS3 compliance. Surface mount packaging requires PCB redesign from the original through-hole HAL108JQ-I layout.

MLX92241LUA-AAA-003-BU is recommended for through-hole retrofit applications where PCB layout compatibility with the original HAL108JQ-I is required. This Melexis part preserves the TO-92-3 package format and extends operating temperature to 150°C. Active product status ensures long-term availability. ROHS3 compliance and REACH Unaffected status provide regulatory flexibility.

Both substitute parts carry active product status, ensuring supply chain continuity beyond the obsolete HAL108JQ-I. Selection between them depends on mounting technology constraints and thermal operating range requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can HAL1506SU-A directly replace HAL108JQ-I on existing PCBs?

A: No. HAL1506SU-A uses SOT-23-3 surface mount packaging, while HAL108JQ-I uses TO-92-3 through-hole packaging. PCB redesign is required. For direct through-hole compatibility, use MLX92241LUA-AAA-003-BU.

Q: What are the key differences in sensing thresholds between these parts?

A: HAL108JQ-I specifies 23.8mT trip and 11.4mT release. HAL1506SU-A specifies 18.9mT trip and 17.3mT release. MLX92241LUA-AAA-003-BU specifies 19.5mT trip and 13mT release. Applications with strict magnetic field detection windows must verify threshold compatibility.

Q: Are all three parts RoHS compliant?

A: Yes. HAL108JQ-I is RoHS Compliant. HAL1506SU-A and MLX92241LUA-AAA-003-BU are ROHS3 Compliant, which satisfies RoHS requirements. MLX92241LUA-AAA-003-BU additionally carries REACH Unaffected status.

Q: Which substitute part supports the widest operating temperature range?

A: MLX92241LUA-AAA-003-BU operates from -40°C to 150°C, exceeding both the original HAL108JQ-I (-20°C to 125°C) and HAL1506SU-A (-40°C to 70°C).

Q: Can I use HAL1506SU-A in applications requiring through-hole mounting?

A: No. HAL1506SU-A is surface mount only (SOT-23-3 package). Through-hole applications must use MLX92241LUA-AAA-003-BU or redesign for surface mount technology.

Q: What is the supply voltage compatibility across all three parts?

A: HAL108JQ-I operates 3.8V ~ 24V. Both HAL1506SU-A and MLX92241LUA-AAA-003-BU operate 2.7V ~ 24V, providing lower voltage operation capability.
