Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE7244SL is determined by strict equivalence across the following critical parameters:

• Switch Type & Output Configuration: Relay/Solenoid Driver with 8 Low-Side N-Channel outputs
• Electrical Specifications: 1:2 Input:Output ratio, 290mA maximum output current, 800mOhm typical on-resistance
• Supply & Load Voltage: 3V ~ 5.5V supply voltage and 4.5V ~ 5.5V load voltage compatibility
• Interface Protocol: SPI control interface
• Fault Protection: Open Load Detect and Over Temperature protection
• Package Compatibility: 24-SSOP surface mount package with identical pinout and thermal characteristics
• Operating Temperature: -40°C ~ 150°C junction temperature range

The TLE7244SLXUMA2 meets all these criteria as a parametric equivalent, maintaining identical electrical performance and mechanical compatibility while differing only in packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The TLE7244SLXUMA2 serves as the direct parametric equivalent for the obsolete TLE7244SL. Both components share identical electrical specifications, pin configuration, and thermal operating range, ensuring drop-in compatibility at the circuit level.

Selection between these parts is determined by product lifecycle and compliance requirements:

• TLE7244SL: Classified as Obsolete. Suitable only for legacy system maintenance and repair applications where existing inventory exists.
• TLE7244SLXUMA2: Classified as Not For New Designs. Offers improved compliance status (ROHS3 Compliant) and represents the transitional equivalent. Appropriate for systems requiring regulatory compliance and extended component availability.

Both components carry REACH Unaffected status and identical ECCN/HTSUS classifications, confirming regulatory equivalence. The TLE7244SLXUMA2 is preferred for applications where RoHS3 compliance is mandated or where component traceability and certification documentation are required.

Frequently Asked Questions (FAQ)

Q: Can TLE7244SLXUMA2 replace TLE7244SL in existing designs?

A: Yes. The TLE7244SLXUMA2 is a parametric equivalent with identical electrical performance, pin configuration, and package dimensions. No circuit modifications are required for direct substitution.

Q: What is the difference between these two part numbers?

A: The primary differences are product lifecycle status and compliance certification. TLE7244SL is Obsolete, while TLE7244SLXUMA2 is Not For New Designs and carries ROHS3 Compliant certification. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both components use the 24-SSOP surface mount package with identical pinout, pitch, and thermal characteristics. PCB layout compatibility is complete.

Q: What does "Not For New Designs" mean for TLE7244SLXUMA2?

A: This status indicates the component is available for current applications but Infineon does not recommend its use in new product development. For new designs, consult Infineon's current product portfolio for recommended alternatives.

Q: Are both parts RoHS compliant?

A: TLE7244SLXUMA2 is explicitly ROHS3 Compliant. TLE7244SL compliance status is not specified in available documentation. For applications requiring RoHS certification, TLE7244SLXUMA2 is the appropriate selection.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 3 (168 Hours), indicating moderate moisture sensitivity. Components must be stored in controlled humidity environments and baked according to IPC standards before reflow soldering to prevent solder joint defects.
