Substitute Part Grouping Explanation

Substitute parts for the MLX90248ESO are identified based on strict electrical and mechanical parameter compatibility. The substitution logic is organized into two categories:

Direct Equivalent (Active Status): MLX90248ESE-EBA-000-RE maintains identical electrical specifications including sensing range (±6mT trip, ±0.8mT release), supply voltage (1.5V ~ 3.6V), supply current (10µA maximum), output current (10mA maximum), and output type (open drain). This part shares the same base product number (MLX90248) and package compatibility (TSOT-23-3 / SOT-23-3). The primary distinction is product status: MLX90248ESE-EBA-000-RE is active, whereas MLX90248ESO is obsolete.

Similar Substitute (Limited Compatibility): AH180N-WG-7 manufactured by Diodes Incorporated provides omnipolar Hall Effect switching functionality with open drain output. However, this part exhibits parameter deviations: sensing range differs (±5mT trip, ±1mT release versus ±6mT trip, ±0.8mT release), supply voltage range is higher (2.5V ~ 5.5V versus 1.5V ~ 3.6V), and supply current is elevated (16µA maximum versus 10µA maximum). AH180N-WG-7 is classified as "Not For New Designs" and serves as a functional alternative only when the MLX90248ESE-EBA-000-RE is unavailable.

Engineering Selection Recommendations

Primary Selection: MLX90248ESE-EBA-000-RE is the recommended substitute for MLX90248ESO. This part is manufactured by the same supplier (Melexis Technologies NV), maintains identical electrical and mechanical specifications, and carries active product status. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. The MLX90248ESE-EBA-000-RE is available in higher inventory quantities (35,100 pieces) and is suitable for new designs.

Secondary Selection: AH180N-WG-7 serves as an alternative when MLX90248ESE-EBA-000-RE is unavailable. This part is manufactured by Diodes Incorporated and provides omnipolar Hall Effect switching with open drain output. However, AH180N-WG-7 exhibits parameter deviations in sensing range, supply voltage, and supply current specifications. Additionally, AH180N-WG-7 is classified as "Not For New Designs," limiting its applicability to legacy or maintenance applications only. Selection of AH180N-WG-7 requires verification that the application tolerates the specified parameter differences.

Frequently Asked Questions (FAQ)

Q: Can MLX90248ESE-EBA-000-RE be used as a direct replacement for MLX90248ESO?

A: Yes. MLX90248ESE-EBA-000-RE is a direct equivalent. Both parts share identical electrical specifications (sensing range ±6mT trip / ±0.8mT release, supply voltage 1.5V ~ 3.6V, supply current 10µA maximum, output current 10mA maximum), identical output type (open drain), identical operating temperature range (-40°C ~ 85°C), and compatible packaging (TSOT-23-3 / SOT-23-3). The primary difference is product status: MLX90248ESE-EBA-000-RE is active, while MLX90248ESO is obsolete.

Q: What are the key parameter differences between MLX90248ESO and AH180N-WG-7?

A: Three parameter deviations exist. First, sensing range differs: AH180N-WG-7 specifies ±5mT trip and ±1mT release, compared to MLX90248ESO's ±6mT trip and ±0.8mT release. Second, supply voltage range is higher for AH180N-WG-7 (2.5V ~ 5.5V versus 1.5V ~ 3.6V). Third, supply current is elevated for AH180N-WG-7 (16µA maximum versus 10µA maximum). These differences may affect circuit performance and power consumption.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts (MLX90248ESO, MLX90248ESE-EBA-000-RE, and AH180N-WG-7) are surface mount components with compatible package designations (TO-236-3, SC-59, SOT-23-3). PCB footprints designed for any of these parts are mechanically compatible with the others.

Q: What is the significance of product status classifications?

A: Product status indicates manufacturer support and design suitability. MLX90248ESO (obsolete) is no longer manufactured or supported. MLX90248ESE-EBA-000-RE (active) is currently manufactured and recommended for new designs. AH180N-WG-7 (not for new designs) is available but not recommended for new applications; it is suitable only for legacy or maintenance purposes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MLX90248ESO, MLX90248ESE-EBA-000-RE, and AH180N-WG-7 are all ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.
