A1301EUA-T Hall Effect Sensor Equivalent & Substitute Parts

Part Overview

The A1301EUA-T is a Hall Effect analog magnetic sensor manufactured by Allegro MicroSystems in a 3-SIP through-hole package. This single-axis sensor outputs analog voltage proportional to magnetic field strength and operates across a -40°C to 85°C temperature range with 4.5V to 6V supply voltage. The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A1301EUA-T is determined by the following critical parameters:

Primary Compatibility Criteria:

• Hall Effect technology with single-axis configuration
• Analog voltage output type
• 3-SIP package and through-hole mounting
• Supply voltage range overlap with 4.5V ~ 6V
• Maximum supply current rating of 11mA or higher
• Maximum output current rating of 10mA or higher
• Bandwidth of 20kHz or higher
• RoHS3 compliance and REACH unaffected status

Both A1308KUA-1-T and A1308KUA-2-T meet these criteria. These parts are active products from the same manufacturer with identical package configurations, electrical characteristics, and compliance certifications. The primary differences are operating temperature ranges and supply voltage upper limits, which represent improvements over the obsolete A1301EUA-T.

Parameter Comparison

Engineering Selection Recommendations

Both A1308KUA-1-T and A1308KUA-2-T are active products suitable for replacing the obsolete A1301EUA-T. Selection between these two substitutes depends on application temperature requirements:

A1308KUA-1-T is appropriate for applications requiring extended high-temperature operation up to 150°C. This part provides the widest operating temperature range and is recommended for thermal-demanding environments.

A1308KUA-2-T is appropriate for applications with moderate temperature requirements up to 125°C. This part maintains full compatibility with the A1301EUA-T electrical specifications while offering improved product status and availability.

Both substitutes are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The supply voltage upper limit reduction from 6V to 5.5V on both substitutes requires verification that application power supplies do not exceed 5.5V nominal operation.

Frequently Asked Questions (FAQ)

Q: Can A1308KUA-1-T and A1308KUA-2-T be used interchangeably with A1301EUA-T?

A: Both parts are direct substitutes for the A1301EUA-T in applications where the supply voltage does not exceed 5.5V and the operating temperature requirement is within the specified range of each substitute. The 3-SSIP package and through-hole mounting are identical, requiring no PCB layout modifications.

Q: What is the primary difference between A1308KUA-1-T and A1308KUA-2-T?

A: The operating temperature range differs. A1308KUA-1-T operates to 150°C, while A1308KUA-2-T operates to 125°C. Both maintain identical electrical performance and package specifications.

Q: Why does the A1301EUA-T have a 6V maximum supply voltage while the substitutes are limited to 5.5V?

A: This specification difference is provided in the manufacturer data. Applications operating at 6V supply voltage require alternative solutions outside this substitute group.

Q: Are there any package or pinout differences between these parts?

A: No. All three parts use the 3-SSIP package with identical through-hole mounting configuration and pinout compatibility.

Q: What compliance certifications apply to these substitutes?

A: Both A1308KUA-1-T and A1308KUA-2-T are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.
