TLE7250GXUMA2 Equivalent & Substitute Parts

Part Overview

The TLE7250GXUMA2 is a half-duplex CANbus transceiver manufactured by Infineon Technologies, designed for automotive and industrial communication applications. This device operates as a 1/1 transceiver with a data rate of 1 Mbps and is housed in an 8-SOIC surface mount package. The part is classified as "Not For New Designs," indicating that Infineon has discontinued active development and support for this component. Due to this product status, identifying functionally equivalent alternatives is essential for ongoing system maintenance, legacy system support, and new design initiatives that require compatible CANbus transceiver functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for CANbus transceiver interfaces is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Protocol compatibility: CANbus half-duplex operation
• Configuration: 1/1 driver/receiver architecture
• Data rate: 1 Mbps operation
• Package type: 8-SOIC surface mount form factor with identical pin pitch (0.154", 3.90mm width)
• Supply voltage range: Must encompass or be compatible with the original 4.75V ~ 5.25V specification
• RoHS compliance: ROHS3 Compliant status maintained

The SN65HVD255DR from Texas Instruments meets all substitution criteria. Both devices operate as half-duplex CANbus transceivers with 1/1 driver/receiver configuration, identical 1 Mbps data rate, and identical 8-SOIC packaging. The supply voltage range of the substitute (4.5V ~ 5.5V) encompasses the original specification, ensuring compatibility across the operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The SN65HVD255DR is the qualified substitute for the TLE7250GXUMA2 based on the following engineering criteria:

Functional Equivalence: Both devices implement identical CANbus half-duplex transceiver architecture with 1/1 driver/receiver configuration and 1 Mbps data rate. Pin-to-pin compatibility is maintained through identical 8-SOIC packaging.

Supply Voltage Compatibility: The SN65HVD255DR supply range (4.5V ~ 5.5V) provides extended coverage relative to the original specification (4.75V ~ 5.25V), ensuring operation across all nominal system voltages.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent component selection.

Product Status Advantage: The SN65HVD255DR carries Active product status, ensuring long-term availability, manufacturing support, and continued compliance updates. This addresses the obsolescence risk associated with the TLE7250GXUMA2 "Not For New Designs" classification.

Receiver Hysteresis Consideration: The SN65HVD255DR specifies 200 mV receiver hysteresis compared to 100 mV for the original part. This parameter difference does not preclude substitution; hysteresis variation within this range is standard across CANbus transceiver implementations and does not affect protocol compliance or signal integrity in typical automotive and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the SN65HVD255DR directly replace the TLE7250GXUMA2 without PCB modifications?

A: Yes. Both devices use identical 8-SOIC packaging with matching pin pitch (0.154", 3.90mm width) and pin assignments for CANbus half-duplex operation. No PCB layout changes are required for mechanical or electrical compatibility.

Q: What is the significance of the receiver hysteresis difference (100 mV vs. 200 mV)?

A: Receiver hysteresis defines the voltage differential between high-to-low and low-to-high threshold transitions. The SN65HVD255DR's 200 mV hysteresis provides enhanced noise immunity compared to the original 100 mV specification. This is a performance advantage in electrically noisy environments and does not compromise compatibility with CANbus protocol specifications.

Q: Are there supply voltage considerations when substituting?

A: The SN65HVD255DR operates across 4.5V ~ 5.5V, which encompasses the original 4.75V ~ 5.25V range. Systems designed for the TLE7250GXUMA2 will operate within the substitute's specification envelope. No power supply redesign is necessary.

Q: Why is the TLE7250GXUMA2 marked "Not For New Designs"?

A: This classification indicates that Infineon has discontinued active development and support for this component line. Existing inventory may remain available, but long-term supply cannot be guaranteed. The SN65HVD255DR, with Active product status, provides assured long-term availability for both legacy system maintenance and new design initiatives.

Q: Are both parts RoHS compliant?

A: Yes. Both the TLE7250GXUMA2 and SN65HVD255DR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What packaging formats are available for the SN65HVD255DR?

A: The SN65HVD255DR is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production volume requirements.
