Key Parameters

Substitute Part Grouping Explanation

Substitution of the US2882LSO is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Function: Latch operation
• Technology: Hall Effect magnetic sensing
• Polarization: South Pole
• Output Type: Open Drain or Open Collector
• Sensing Range: Magnetic trip and release thresholds
• Voltage Supply Range: Operating voltage compatibility
• Current Ratings: Supply and output current specifications
• Operating Temperature Range: Thermal performance envelope
• Package Compatibility: Physical form factor and pinout

Substitution Categories:

Direct Equivalent: US2882LSE-AAA-000-RE maintains identical electrical specifications and function while offering active product status and improved packaging (Tape & Reel). This part shares the same base product number (US2882) and is the primary direct replacement.

Similar Substitute: TLE4946KHTSA1 provides functional equivalence as a Hall Effect latch magnetic sensor with south pole polarization and open collector output. This Infineon Technologies component operates within compatible voltage and temperature ranges but exhibits different sensing thresholds and current ratings that require application-level verification.

Engineering Selection Recommendations

US2882LSE-AAA-000-RE (Direct Equivalent - Recommended Primary Choice)

The US2882LSE-AAA-000-RE is the recommended direct substitute for the obsolete US2882LSO. This part maintains identical electrical specifications including sensing range (6mT trip, -6mT release), voltage supply range (3.5V ~ 24V), current ratings (5mA supply, 50mA output), and operating temperature envelope (-40°C ~ 150°C). Both components share the same base product number (US2882) and are manufactured by Melexis Technologies NV. The primary distinction is product status: US2882LSE-AAA-000-RE is active with 29,400 units in stock and supplied in Tape & Reel packaging, ensuring long-term availability and procurement reliability. ROHS3 compliance and MSL 1 rating are maintained. This part provides direct pin-compatible replacement without circuit modification.

TLE4946KHTSA1 (Similar Substitute - Application-Dependent)

The TLE4946KHTSA1 manufactured by Infineon Technologies functions as a Hall Effect latch magnetic sensor with south pole polarization and is classified as active product status. This component shares the same physical package form factor (TO-236-3, SC-59, SOT-23-3) and operating temperature range (-40°C ~ 150°C). However, critical parameter differences exist that affect application compatibility:

• Sensing Range: 19mT trip and -19mT release (versus 6mT for US2882LSO)
• Voltage Supply: 2.7V ~ 18V (narrower upper limit than 24V)
• Current Output (Max): 20mA (versus 50mA)
• Output Type: Open Collector (versus Open Drain)

The TLE4946KHTSA1 includes temperature compensation and carries AEC-Q100 automotive qualification. Selection of this part requires confirmation that the higher magnetic sensing threshold (19mT versus 6mT) aligns with application requirements and that the reduced output current rating (20mA versus 50mA) is acceptable for the load circuit.

Frequently Asked Questions (FAQ)

Q: Why is the US2882LSO classified as obsolete?

A: The US2882LSO has reached end-of-life status with Melexis Technologies NV. The active equivalent US2882LSE-AAA-000-RE provides identical electrical function and specifications while maintaining current manufacturing and supply chain support.

Q: Can US2882LSE-AAA-000-RE be used as a direct replacement without circuit modification?

A: Yes. The US2882LSE-AAA-000-RE maintains identical electrical specifications, output type (open drain), sensing range (6mT trip, -6mT release), voltage supply range (3.5V ~ 24V), current ratings, and operating temperature range (-40°C ~ 150°C). Pin configuration and package form factor are compatible. No circuit modification is required.

Q: What are the key differences between US2882LSO and TLE4946KHTSA1?

A: The primary differences are: (1) Sensing Range: TLE4946KHTSA1 requires 19mT magnetic field for trip versus 6mT for US2882LSO; (2) Output Current: TLE4946KHTSA1 maximum output is 20mA versus 50mA; (3) Output Type: TLE4946KHTSA1 uses open collector versus open drain; (4) Voltage Supply Upper Limit: TLE4946KHTSA1 maximum is 18V versus 24V. These differences may affect circuit performance and load compatibility.

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

A: No. The TLE4946KHTSA1 has a magnetic trip threshold of 19mT, which is significantly higher than the 6mT specification of the US2882LSO. Applications requiring 6mT sensitivity must use US2882LSO or US2882LSE-AAA-000-RE.

Q: Are all three parts RoHS3 compliant?

A: Yes. US2882LSO, US2882LSE-AAA-000-RE, and TLE4946KHTSA1 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between SOT-23 and TSOT-23-3 packaging?

A: Both designations refer to the same physical form factor (TO-236-3, SC-59, SOT-23-3). The primary difference is packaging format: US2882LSO is supplied in standard packaging, while US2882LSE-AAA-000-RE is supplied in Tape & Reel (TR) format for automated assembly processes. Pin configuration and electrical performance are identical.

Q: Can the TLE4946KHTSA1 be used in 24V supply applications?

A: No. The TLE4946KHTSA1 maximum supply voltage is 18V. Applications requiring 24V operation must use US2882LSO or US2882LSE-AAA-000-RE, which support 3.5V ~ 24V supply range.

Q: What is the inventory status for each part?

A: US2882LSO has 830 units in stock (obsolete status). US2882LSE-AAA-000-RE has 29,400 units in stock (active status). TLE4946KHTSA1 has 56,400 units in stock (active status). For long-term procurement, US2882LSE-AAA-000-RE is the recommended choice due to active product status and higher inventory levels.
