A1213EUA-T Equivalent & Substitute Parts

Part Overview

The A1213EUA-T is a digital switch latch Hall Effect magnetic sensor manufactured by Allegro MicroSystems, housed in a 3-SIP through-hole package. This component functions as an open drain output magnetic switch with south pole polarization, designed for applications requiring latching magnetic sensing functionality. The A1213EUA-T is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the A1213EUA-T is determined by strict equivalence across the following critical parameters:

• Hall Effect technology with south pole polarization
• Identical sensing range: 20mT trip threshold and -20mT release threshold
• Open drain output configuration
• Supply voltage range: 3.8V ~ 24V
• Maximum supply current: 7.5mA
• Maximum output current: 25mA
• Through-hole mounting in 3-SSIP package
• Latch function operation

The A1213LUA-T meets all these criteria and is classified as the manufacturer-recommended substitute. The primary distinction between the main part and substitute is product status and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The A1213LUA-T is the direct substitute for the obsolete A1213EUA-T. Both components maintain identical electrical and mechanical specifications across all critical parameters. The A1213LUA-T carries active product status from Allegro MicroSystems, ensuring ongoing availability and manufacturing support.

The A1213LUA-T provides an extended operating temperature range of -40°C ~ 150°C compared to the A1213EUA-T range of -40°C ~ 85°C. This extended range does not restrict compatibility; applications operating within the original -40°C ~ 85°C specification remain fully compatible.

Both parts maintain ROHS3 compliance and identical moisture sensitivity classification, supporting equivalent environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the A1213LUA-T directly replace the A1213EUA-T in existing designs?

A: Yes. The A1213LUA-T is electrically and mechanically equivalent to the A1213EUA-T across all specified parameters, including sensing range, supply voltage, output current, and package configuration.

Q: What is the primary reason for substitution?

A: The A1213EUA-T is classified as obsolete. The A1213LUA-T is the active equivalent part from the same manufacturer, ensuring continued availability for production and new designs.

Q: Are there differences in operating temperature ranges?

A: The A1213LUA-T operates across -40°C ~ 150°C, while the A1213EUA-T operates across -40°C ~ 85°C. Applications using the A1213EUA-T within its specified temperature range are fully compatible with the A1213LUA-T.

Q: Do both parts use the same package?

A: Yes. Both the A1213EUA-T and A1213LUA-T use the 3-SSIP through-hole package, requiring no PCB layout modifications.

Q: Are compliance certifications equivalent?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity classification (MSL 1).
