TLE6251DXUMA1 Equivalent & Substitute Parts

Part Overview

The TLE6251DXUMA1 is a full-duplex CANbus transceiver manufactured by Infineon Technologies, designed for automotive and industrial communication applications. This interface IC operates as a 1/1 transceiver with integrated driver and receiver functionality in an 8-SOIC surface mount package. The part is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent substitute parts is necessary for ongoing system support, maintenance, and component procurement when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE6251DXUMA1 is determined by the following critical parameters:

Functional Equivalence: Both the main part and substitute must maintain identical CANbus protocol support, 1/1 transceiver configuration, full-duplex operation, and 1 MBd data rate capability.

Package Compatibility: The 8-SOIC (0.154", 3.90mm Width) surface mount package must remain consistent to ensure PCB layout and assembly compatibility without redesign.

Electrical Performance: Operating temperature range (-40°C ~ 150°C) and receiver hysteresis (200 mV) must be maintained to preserve circuit behavior and thermal performance specifications.

Compliance & Certification: RoHS3 compliance and REACH unaffected status must be retained for regulatory and supply chain requirements.

Supply Voltage Tolerance: While the main part specifies 4.5V ~ 5.5V and the substitute specifies 4.75V ~ 5.25V, both ranges overlap sufficiently within standard 5V supply applications, making this an acceptable variation for substitution purposes.

Parameter Comparison

Engineering Selection Recommendations

The TLE6251DXUMA2 is a direct functional substitute for the TLE6251DXUMA1. Both parts share identical CANbus transceiver architecture, electrical performance characteristics, and physical packaging requirements.

The primary distinction is product lifecycle status: the TLE6251DXUMA1 is designated "Not For New Designs," while the TLE6251DXUMA2 maintains "Active" status. This makes the TLE6251DXUMA2 the preferred selection for ongoing production, maintenance, and component replenishment activities.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for automotive and industrial applications. The supply voltage specification difference (4.5V ~ 5.5V versus 4.75V ~ 5.25V) is operationally compatible within standard 5V supply systems.

The TLE6251DXUMA2 features improved moisture sensitivity (MSL 2A, 4 weeks) compared to the main part (MSL 3, 168 hours), providing enhanced handling flexibility during storage and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the TLE6251DXUMA2 be used as a direct replacement for the TLE6251DXUMA1 without PCB modifications?

A: Yes. Both parts use identical 8-SOIC (0.154", 3.90mm Width) packaging and PG-DSO-8-16 supplier device package specifications. No PCB layout changes are required for substitution.

Q: Are there electrical performance differences between these parts?

A: Both parts maintain identical CANbus protocol support, 1/1 transceiver configuration, 1 MBd data rate, 200 mV receiver hysteresis, and -40°C ~ 150°C operating temperature range. The supply voltage specification differs slightly (4.5V ~ 5.5V versus 4.75V ~ 5.25V), but both ranges are compatible with standard 5V supply applications.

Q: Why is the TLE6251DXUMA1 marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status. The TLE6251DXUMA2 is the active production equivalent and should be used for new designs and ongoing procurement.

Q: What is the difference in moisture sensitivity between these parts?

A: The TLE6251DXUMA1 has MSL 3 (168 hours), while the TLE6251DXUMA2 has MSL 2A (4 weeks). The improved MSL rating of the substitute part provides extended shelf life and reduced risk of moisture-related failures during storage and assembly.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the TLE6251DXUMA1 and TLE6251DXUMA2 are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for automotive and industrial applications.

Q: What packaging formats are available for the TLE6251DXUMA2?

A: The TLE6251DXUMA2 is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for different procurement and assembly workflows.
