Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE7258DXUMA1 is determined by strict equivalence across the following critical parameters:

• Protocol: LINbus
• Number of Drivers/Receivers: 1/1
• Receiver Hysteresis: 120 mV
• Data Rate: 20kbps
• Voltage - Supply: 5.5V ~ 18V
• Operating Temperature: -40°C ~ 150°C
• RoHS Status: ROHS3 Compliant

Two substitute parts meet these electrical and functional requirements. The TLE7258LEXUMA1 maintains identical package specifications (8-TDFN Exposed Pad), while the TLE7258SJXUMA1 provides functional equivalence with a different package form factor (8-SOIC). Both alternatives are manufactured by Infineon Technologies under the same base product number TLE7258 and support the complete operational parameter set of the obsolete TLE7258DXUMA1.

Parameter Comparison

Engineering Selection Recommendations

The TLE7258LEXUMA1 is the direct parametric equivalent to the obsolete TLE7258DXUMA1, maintaining identical package specifications (8-TDFN Exposed Pad with Wettable Flank) and all electrical parameters. This part is currently in active production status and carries ROHS3 compliance certification. The TLE7258LEXUMA1 is suitable for direct replacement in existing designs without PCB layout modifications.

The TLE7258SJXUMA1 is the manufacturer-recommended alternative, offering full functional equivalence across all electrical parameters while utilizing an 8-SOIC package form factor. This part is also in active production status with ROHS3 compliance. Selection of the TLE7258SJXUMA1 requires PCB redesign to accommodate the different package footprint but provides an alternative sourcing option with higher current inventory availability.

Both substitute parts are manufactured by Infineon Technologies and meet all regulatory and compliance requirements of the original component.

Frequently Asked Questions (FAQ)

Q: Can the TLE7258LEXUMA1 be used as a direct replacement for the TLE7258DXUMA1?

A: Yes. The TLE7258LEXUMA1 maintains identical electrical specifications, package form factor (8-TDFN Exposed Pad), and mounting characteristics. No PCB modifications are required for this substitution.

Q: What is the primary difference between the TLE7258LEXUMA1 and TLE7258SJXUMA1?

A: The primary difference is the package form factor. The TLE7258LEXUMA1 uses an 8-TDFN Exposed Pad package, while the TLE7258SJXUMA1 uses an 8-SOIC package. Both maintain identical LINbus transceiver functionality and electrical parameters. Package selection depends on PCB layout constraints and manufacturing capabilities.

Q: Are both substitute parts suitable for automotive applications?

A: Both the TLE7258LEXUMA1 and TLE7258SJXUMA1 support the full operating temperature range of -40°C to 150°C and are ROHS3 compliant, meeting automotive industry standards. Specific application qualification should be verified against system requirements.

Q: What is the difference in Moisture Sensitivity Level (MSL) between the main part and substitutes?

A: The TLE7258DXUMA1 has MSL 2A (4 Weeks), while both substitute parts have MSL 3 (168 Hours). This affects storage and handling procedures. Parts with MSL 3 require baking before reflow if storage time exceeds 168 hours in standard humidity conditions.

Q: Why is the TLE7258DXUMA1 classified as obsolete?

A: The TLE7258DXUMA1 has reached end-of-life status. The TLE7258LEXUMA1 and TLE7258SJXUMA1 are the active production alternatives from Infineon Technologies for this LINbus transceiver function.
