Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE6281GXUMA1 is determined by the following critical parameters:

Motor control function (brushed DC commutation and direction management), output configuration (pre-driver half bridge topology), technology platform (power MOSFET), mounting type (surface mount), and package form factor (20-SOIC). The substitute part must maintain compatibility with these core functional and physical attributes.

The L9903TR from STMicroelectronics meets the functional requirements for motor driver control but operates within a reduced supply voltage range (8V ~ 20V) compared to the TLE6281GXUMA1 (7.5V ~ 60V). This voltage limitation must be evaluated against specific application requirements. Both devices share identical package geometry, operating temperature range, and MSL rating, enabling direct physical and thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

The L9903TR is the manufacturer-recommended substitute for the TLE6281GXUMA1. Both devices share identical package geometry, thermal operating range, and moisture sensitivity specifications, enabling direct physical replacement on existing PCB layouts.

The primary design consideration is the supply voltage operating range. The TLE6281GXUMA1 supports 7.5V to 60V operation, while the L9903TR operates within 8V to 20V. Applications requiring supply voltages above 20V or below 8V cannot use the L9903TR as a direct substitute without additional circuit modifications.

The L9903TR holds active product status with RoHS3 compliance, ensuring ongoing availability and regulatory alignment. Both devices maintain identical REACH and ECCN classifications, supporting consistent supply chain and export compliance requirements.

Interface differences exist between the devices: the TLE6281GXUMA1 uses PWM control, while the L9903TR employs serial interface control. Application firmware and control circuitry must be evaluated for compatibility with the serial interface protocol.

Frequently Asked Questions (FAQ)

Q: Can the L9903TR directly replace the TLE6281GXUMA1 in all applications?

A: Physical and thermal compatibility is confirmed due to identical package geometry and operating temperature range. However, supply voltage range and control interface differences must be verified. Applications operating above 20V supply voltage require alternative solutions.

Q: What is the primary limitation of the L9903TR as a substitute?

A: The L9903TR operates within a reduced supply voltage range of 8V to 20V, compared to the TLE6281GXUMA1 range of 7.5V to 60V. Applications requiring higher supply voltages cannot use this substitute without external voltage regulation or alternative component selection.

Q: Are there interface compatibility concerns between these devices?

A: Yes. The TLE6281GXUMA1 uses PWM-based control, while the L9903TR employs serial interface control. Control circuitry and firmware must be adapted to accommodate the serial protocol requirements of the L9903TR.

Q: Do both devices share identical package specifications?

A: Yes. Both the TLE6281GXUMA1 and L9903TR are packaged in 20-SOIC (0.295", 7.50mm Width) form factor, enabling direct PCB layout compatibility without redesign.

Q: What is the product status difference between these devices?

A: The TLE6281GXUMA1 is classified as obsolete, while the L9903TR maintains active product status. The L9903TR also carries RoHS3 compliance certification, supporting current regulatory requirements.

Q: Are moisture sensitivity and thermal specifications identical?

A: Yes. Both devices share MSL rating 3 (168 Hours) and identical operating temperature range of -40°C to 150°C (TJ), confirming equivalent handling, storage, and thermal performance characteristics.
