TLE6251DST CANbus Transceiver Equivalent & Substitute Parts

Part Overview

The TLE6251DST is a full-duplex CANbus transceiver manufactured by Infineon Technologies, designed for automotive and industrial communication applications. This 1/1 transceiver IC operates at 1 MBd data rate with integrated driver and receiver functionality in an 8-SOIC surface mount package.

The TLE6251DST has been discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE6251DST is determined by strict equivalence across the following parameters:

• Protocol: CANbus (required match)
• Transceiver configuration: 1/1 driver/receiver (required match)
• Duplex mode: Full (required match)
• Data rate: 1 MBd (required match)
• Receiver hysteresis: 200 mV (required match)
• Supply voltage range: 4.75V ~ 5.25V (required match)
• Operating temperature range: -40°C ~ 150°C (required match)
• Package type: 8-SOIC with 0.154" width, 3.90mm width (required match)

All identified substitute parts meet these electrical and mechanical criteria, enabling direct replacement in circuit designs without modification to PCB layout or electrical connections.

Parameter Comparison

Engineering Selection Recommendations

TLE6251DXUMA2 is the primary substitute for new applications and replacement scenarios. This part maintains full electrical and mechanical equivalence to the TLE6251DST while offering active product status and ROHS3 compliance. Availability is substantial at 65,614 units in stock.

TLE6251DSXUMA2 serves as an alternative substitute with equivalent electrical specifications and ROHS3 compliance. Product status is classified as "Not For New Designs," limiting its application to legacy system maintenance where existing design validation has been completed. Inventory availability is 2,800 units.

Both substitute parts require consideration of moisture sensitivity level (MSL 2A, 4 weeks) compared to the original part (MSL 1, unlimited). Storage and handling procedures must align with MSL 2A requirements to maintain component reliability.

Frequently Asked Questions (FAQ)

Q: Can TLE6251DXUMA2 directly replace TLE6251DST without PCB modification?

A: Yes. Both parts share identical electrical specifications (1 MBd CANbus, 1/1 transceiver, full-duplex, 4.75V–5.25V supply, -40°C to 150°C operating range) and package geometry (8-SOIC, 0.154" width, 3.90mm width). No PCB layout changes are required.

Q: What is the difference between TLE6251DSXUMA2 and TLE6251DXUMA2?

A: Both parts are electrically equivalent. The primary differences are product status (TLE6251DSXUMA2 is "Not For New Designs" while TLE6251DXUMA2 is "Active") and inventory availability (TLE6251DXUMA2 has significantly higher stock levels). For new designs, TLE6251DXUMA2 is the recommended choice.

Q: Does the MSL 2A rating of substitute parts affect compatibility?

A: MSL 2A (4 weeks) indicates moisture sensitivity requiring controlled storage and handling conditions. This differs from the original part's MSL 1 (unlimited) rating but does not affect electrical or mechanical compatibility. Proper moisture control during storage and assembly is necessary to maintain component reliability.

Q: Are all substitute parts RoHS compliant?

A: TLE6251DSXUMA2 and TLE6251DXUMA2 are both ROHS3 compliant. The original TLE6251DST is RoHS non-compliant. If RoHS compliance is a design requirement, substitute parts satisfy this criterion.

Q: What is the base product number relationship?

A: All three parts (TLE6251DST, TLE6251DSXUMA2, TLE6251DXUMA2) share the base product number TLE6251, indicating they are variants within the same product family with identical core functionality.
