Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLE9251LEXUMA1 are qualified based on strict equivalence across the following critical parameters: manufacturer (Infineon Technologies), base product number (TLE9251), protocol (CANbus), transceiver configuration (1/1 half-duplex), data rate (5 Mbps), supply voltage range (4.5V – 5.5V), operating temperature range (-40°C to +150°C), package type (8-TDFN Exposed Pad), receiver hysteresis (30 mV), automotive grade classification, AEC-Q100 qualification, and RoHS3 compliance. Substitution is permitted only when all these parameters remain identical. Packaging format (Tape & Reel, Cut Tape, or Digi-Reel) and moisture sensitivity level (MSL) are secondary considerations that do not affect electrical or mechanical compatibility but may influence procurement and storage requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TLE9251LEXUMA1, TLE9251VLEXUMA1, and TLT9251VLEXUMA1—are electrically and mechanically equivalent and maintain identical functional performance in CANbus transceiver applications. Selection between these parts should be based on packaging and procurement requirements rather than technical performance differences.

TLE9251LEXUMA1 is supplied in Tape & Reel format with MSL 3 rating (168-hour moisture protection window). This configuration is suitable for standard manufacturing environments with typical moisture exposure profiles.

TLE9251VLEXUMA1 is supplied in Cut Tape and Digi-Reel format with MSL 2A rating (4-week moisture protection window), offering enhanced moisture protection and alternative packaging for automated pick-and-place operations.

TLT9251VLEXUMA1 is supplied in Tape & Reel format with MSL 2A rating, combining standard reel packaging with improved moisture sensitivity characteristics.

All parts carry active product status, AEC-Q100 automotive qualification, and ROHS3 compliance, confirming suitability for automotive applications requiring long-term reliability and regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Are TLE9251VLEXUMA1 and TLT9251VLEXUMA1 direct replacements for TLE9251LEXUMA1?

A: Yes. All three parts are electrically and mechanically equivalent. They share identical CANbus transceiver specifications, including 1/1 half-duplex configuration, 5 Mbps data rate, 4.5V–5.5V supply voltage, -40°C to +150°C operating temperature range, 8-TDFN package, and AEC-Q100 qualification. Substitution is valid for any application using the TLE9251LEXUMA1.

Q: What is the difference between the packaging formats?

A: TLE9251LEXUMA1 and TLT9251VLEXUMA1 are supplied in Tape & Reel format, suitable for standard reel-fed assembly equipment. TLE9251VLEXUMA1 is supplied in Cut Tape and Digi-Reel format, which may be preferred for lower-volume production runs or specific automated assembly systems. Electrical performance is identical across all packaging formats.

Q: Does moisture sensitivity level affect part selection?

A: Moisture sensitivity level (MSL) affects storage and handling procedures but not electrical performance. TLE9251LEXUMA1 has MSL 3 (168-hour protection), while TLE9251VLEXUMA1 and TLT9251VLEXUMA1 have MSL 2A (4-week protection). Higher MSL ratings provide longer moisture protection windows and may reduce baking requirements in humid environments. Selection should align with your manufacturing environment and storage capabilities.

Q: Can these parts be used interchangeably in automotive applications?

A: Yes. All three parts carry AEC-Q100 automotive qualification and ROHS3 compliance, confirming their suitability for automotive CAN bus networks. They are functionally interchangeable in any design using the TLE9251LEXUMA1.

Q: Are there any pin-to-pin or footprint differences?

A: No. All parts use the identical 8-TDFN Exposed Pad package (PG-TSON-8-1) with identical pinout and footprint. PCB layout and schematic connections require no modification when substituting between these parts.
