HAL203JQ-K Equivalent & Substitute Parts

Part Overview

The HAL203JQ-K is a digital switch latch Hall Effect magnetic sensor manufactured by TDK-Micronas GmbH in TO-92UA-5 packaging. This component operates as an open drain output device with temperature compensation, designed for magnetic field detection applications requiring latch functionality. The product is currently obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure supply chain availability for new production and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HAL203JQ-K is determined by the following critical parameters:

Functional Equivalence: Both the main part and substitute must operate as latch-type Hall Effect magnetic sensors with open drain output configuration and south pole polarization.

Electrical Compatibility: Supply voltage range, maximum supply current, and maximum output current must be compatible with the application circuit. The substitute must operate within the specified voltage window and current limits.

Mechanical Compatibility: Through-hole mounting type and TO-92-3 Short Body package ensure physical interchangeability in existing PCB designs.

Environmental Performance: Operating temperature range and temperature compensation features must support the intended application environment.

Regulatory Compliance: RoHS compliance status ensures adherence to hazardous substance restrictions.

The US2882LUA-AAA-000-BU from Melexis Technologies NV meets these substitution criteria as an active product with compatible electrical and mechanical specifications.

Engineering Selection Recommendations

The US2882LUA-AAA-000-BU is the qualified substitute for the obsolete HAL203JQ-K based on the following engineering criteria:

Product Status: The substitute is an active product with current manufacturing support, ensuring long-term availability and supply chain stability compared to the obsolete main part.

Regulatory Compliance: Both components maintain RoHS compliance. The substitute achieves ROHS3 compliance, meeting current regulatory requirements for hazardous substance restrictions.

Electrical Specifications: The substitute operates within compatible voltage and current parameters. The supply voltage range of 4.6V ~ 24V encompasses the main part's 3.8V ~ 140V specification. Maximum supply current of 5mA and output current of 50mA remain within acceptable limits for equivalent circuit operation.

Thermal Performance: The substitute extends the upper operating temperature limit to 150°C, providing enhanced thermal margin compared to the main part's 140°C maximum.

Physical Interchangeability: Identical through-hole mounting and TO-92-3 Short Body packaging enable direct PCB-level replacement without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the US2882LUA-AAA-000-BU directly replace the HAL203JQ-K in existing designs?

A: Yes. Both components share identical mechanical packaging (TO-92-3 Short Body), through-hole mounting configuration, and compatible electrical specifications. Direct PCB substitution is possible without design modifications.

Q: What are the key differences in sensing range between these components?

A: The HAL203JQ-K operates with a sensing range of 11.5mT trip and -11.5mT release. The US2882LUA-AAA-000-BU operates with a sensing range of 6mT trip and -6mT release. Applications requiring the specific trip/release thresholds of the original part must evaluate whether the substitute's different sensing range is compatible with the magnetic field environment.

Q: Are there voltage supply compatibility concerns?

A: The substitute's supply voltage range of 4.6V ~ 24V is compatible with the main part's 3.8V ~ 24V specification. Applications operating at voltages below 3.8V may require evaluation of the substitute's performance at the lower voltage threshold.

Q: Does the substitute maintain temperature compensation?

A: The main part specifies temperature compensation as a feature. The substitute does not list temperature compensation in the provided specifications. Applications dependent on temperature-compensated operation must evaluate this difference.

Q: What is the significance of the different test conditions?

A: The main part specifies test conditions at 25°C, while the substitute specifies test conditions at 150°C. This indicates the substitute's specifications are validated at a higher temperature, reflecting its extended operating range to 150°C.

Q: Are both components RoHS compliant?

A: Yes. The HAL203JQ-K is RoHS Compliant. The US2882LUA-AAA-000-BU is ROHS3 Compliant, meeting current regulatory standards for hazardous substance restrictions.
