TLE7258LEXUMA1 Equivalent & Substitute Parts

Part Overview

The TLE7258LEXUMA1 is a 1/1 LINbus transceiver IC manufactured by Infineon Technologies in an 8-TDFN Exposed Pad package. This interface component operates across a supply voltage range of 5.5V to 18V and supports data rates up to 20kbps with a receiver hysteresis of 120 mV. The part is currently in Active product status with 5100 units available in new original inventory. Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design revisions require compatible alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE7258LEXUMA1 is determined by strict equivalence across the following critical parameters:

• Protocol specification (LINbus)
• Driver/Receiver configuration (1/1)
• Receiver hysteresis (120 mV)
• Data rate capability (20kbps)
• Supply voltage range (5.5V ~ 18V)
• Operating temperature range (-40°C ~ 150°C)
• Package type (8-TDFN Exposed Pad)
• Mounting technology (Surface Mount, Wettable Flank)
• Regulatory compliance (ROHS3, REACH Unaffected, EAR99)

The TLE7258DXUMA1 meets all electrical and mechanical substitution criteria. Differences in product status and moisture sensitivity level do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The TLE7258LEXUMA1 is the preferred selection for new designs and production applications due to its Active product status and current availability of 5100 units in inventory. This part provides long-term supply assurance and manufacturer support.

The TLE7258DXUMA1 is electrically and mechanically equivalent and maintains full functional compatibility. However, its Obsolete product status indicates discontinued manufacturing. This part is suitable only for legacy system maintenance, repair operations, or applications where existing inventory is available. The MSL rating difference (3 versus 2A) reflects different manufacturing process conditions but does not affect circuit performance or reliability in standard operating environments.

Both parts satisfy ROHS3 compliance and REACH regulatory requirements, making them suitable for applications subject to environmental standards.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically identical across all functional parameters including protocol, data rate, voltage range, temperature range, and package specifications. The primary difference is product status; TLE7258DXUMA1 is obsolete while TLE7258LEXUMA1 is active.

Q: What is the significance of the different MSL ratings?

A: MSL (Moisture Sensitivity Level) indicates the maximum time a component can be stored in ambient conditions before requiring baking. TLE7258LEXUMA1 has MSL 3 (168 hours), while TLE7258DXUMA1 has MSL 2A (4 weeks). Both ratings are within acceptable industrial handling standards and do not affect functional performance.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the identical 8-TDFN Exposed Pad package (PG-TSON-8-1) with Surface Mount, Wettable Flank mounting technology. Pinout and footprint are identical.

Q: Which part should be selected for new production designs?

A: TLE7258LEXUMA1 should be selected for new designs due to its Active status and assured long-term availability. TLE7258DXUMA1 should be reserved for legacy system support only.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.
