US2882ESO Equivalent & Substitute Parts

Part Overview

The US2882ESO is a digital switch latch Hall Effect magnetic sensor manufactured by Melexis Technologies NV in SOT-23 surface mount packaging. This component functions as an open drain magnetic switch with south pole polarization, designed for applications requiring latching magnetic detection across industrial and consumer electronics. The US2882ESO is classified as obsolete product status, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the US2882ESO are identified based on strict electrical and mechanical parameter compatibility within the magnetic sensor category. The primary substitution criteria are:

Critical Matching Parameters:

• Function: Latch operation
• Technology: Hall Effect
• Polarization: South Pole
• Output Type: Open Drain or Open Collector
• Package Compatibility: TO-236-3, SC-59, SOT-23-3 physical footprint
• Mounting Type: Surface Mount
• Supply Voltage Range: Overlap with 3.5V ~ 24V
• Operating Temperature: Minimum -40°C, maximum 85°C or higher

Substitute Categories:

Direct Manufacturer Equivalent: US2882ESE-AAA-000-RE is the active production variant from Melexis Technologies NV. This part maintains identical electrical specifications (sensing range, supply voltage, current ratings, output type) and physical package compatibility. The primary difference is packaging format (Tape & Reel versus bulk) and active product status.

Cross-Manufacturer Alternative: TLE4946KHTSA1 from Infineon Technologies is a similar Hall Effect latch magnetic sensor with compatible physical packaging and functional operation. This part operates within overlapping supply voltage ranges and maintains south pole polarization. Differences include higher sensing range threshold (19mT versus 6mT), extended operating temperature range (-40°C ~ 150°C), and open collector output configuration.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): US2882ESE-AAA-000-RE is the recommended substitute for obsolete US2882ESO applications. This part is manufactured by the same supplier (Melexis Technologies NV), maintains identical electrical specifications, and carries active product status with confirmed inventory availability. Both parts are ROHS3 compliant and REACH unaffected, ensuring regulatory continuity. The packaging format difference (Tape & Reel for the substitute) does not affect electrical or mechanical compatibility.

For Cross-Manufacturer Substitution: TLE4946KHTSA1 from Infineon Technologies is suitable for applications where the higher sensing range threshold (19mT versus 6mT) and extended operating temperature capability (-40°C ~ 150°C) are acceptable or beneficial. This part is automotive-qualified (AEC-Q100) and includes temperature compensation features. The reduced output current rating (20mA versus 50mA) and supply voltage upper limit (18V versus 24V) must be evaluated against specific circuit requirements. Open collector output configuration requires verification of pull-up resistor compatibility with existing designs.

Compliance Considerations: All three parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels, supporting seamless integration into regulated manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can US2882ESE-AAA-000-RE directly replace US2882ESO in existing designs?

A: Yes. Both parts are manufactured by Melexis Technologies NV with identical electrical specifications (sensing range, supply voltage, current ratings, output type, and operating temperature range). Physical package compatibility is confirmed across TO-236-3, SC-59, and SOT-23-3 designations. The only difference is packaging format (Tape & Reel versus bulk), which does not affect circuit performance.

Q: What are the key differences between US2882ESO and TLE4946KHTSA1?

A: The primary differences are: (1) Sensing range threshold is higher for TLE4946KHTSA1 (19mT trip versus 6mT trip), requiring stronger magnetic fields for activation; (2) Output type differs (open collector versus open drain), affecting pull-up circuit design; (3) Maximum output current is lower for TLE4946KHTSA1 (20mA versus 50mA); (4) Supply voltage upper limit is lower for TLE4946KHTSA1 (18V versus 24V); (5) Operating temperature range is extended for TLE4946KHTSA1 (-40°C ~ 150°C versus -40°C ~ 85°C).

Q: Is TLE4946KHTSA1 suitable for applications requiring 6mT sensitivity?

A: No. TLE4946KHTSA1 has a 19mT trip threshold, which is significantly higher than the 6mT specification of US2882ESO. This part is not suitable for applications requiring the lower sensitivity level of the original component.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. US2882ESE-AAA-000-RE and TLE4946KHTSA1 are both ROHS3 compliant, matching the compliance status of the obsolete US2882ESO.

Q: What is the difference between open drain and open collector outputs?

A: Both are switch-type outputs that require external pull-up resistors. Open drain uses an N-channel MOSFET output stage, while open collector uses a bipolar transistor output stage. Circuit compatibility depends on pull-up resistor selection and load characteristics. Verify pull-up resistor values and load impedance when substituting between these output types.

Q: Can I use TLE4946KHTSA1 in a 24V supply circuit?

A: No. TLE4946KHTSA1 has a maximum supply voltage of 18V, while US2882ESO supports up to 24V. Using TLE4946KHTSA1 in a 24V circuit will exceed its rated supply voltage and cause component failure.

Q: What is the inventory status of substitute parts?

A: US2882ESE-AAA-000-RE has 1059 pieces in stock. TLE4946KHTSA1 has 56400 pieces in stock. Both are available as new original components.
