Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE7243SLXUMA2 is determined by the following critical parameters: output configuration (Low Side), output type (N-Channel), number of outputs (8), input:output ratio (1:2), interface type (SPI), voltage operating ranges (Load: 4.5V ~ 5.5V; Supply: 3V ~ 5.5V), operating temperature range (-40°C ~ 150°C), mounting type (Surface Mount), and fault protection features (Open Load Detect, Over Temperature).

Substitute parts are grouped into three categories:

Direct Manufacturer Substitute: TLE7244SLXUMA2 maintains identical electrical architecture and packaging while offering increased output current capacity (290mA vs. 260mA) and improved on-resistance (800mOhm vs. 1.2Ohm).

Manufacturer Recommended Substitute: TLE8108EMXUMA1 represents the active production alternative with enhanced current capability (400mA) and updated packaging designation (PG-SSOP-24 with exposed pad), maintaining all core functional parameters.

Parametric Equivalent: TLE7243SLFUMA1 provides identical electrical specifications to the main part with active product status, differing only in packaging variant designation while maintaining the same physical footprint and pin configuration.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing procurement, TLE7243SLFUMA1 is the preferred parametric equivalent, offering identical electrical performance to the TLE7243SLXUMA2 with Active product status and full ROHS3 compliance. This part maintains the original 260mA output current and 1.2Ohm on-resistance specifications while ensuring long-term availability and manufacturing support.

TLE8108EMXUMA1 serves as the manufacturer-recommended upgrade path, providing enhanced current capability (400mA) and improved thermal performance (800mOhm on-resistance) within an updated package variant (24-LSSOP with exposed pad). This part is in active production with the highest inventory availability and is suitable for applications requiring increased output current headroom.

TLE7244SLXUMA2 functions as an intermediate direct substitute with improved specifications (290mA, 800mOhm) but carries "Not For New Designs" status, limiting its suitability to legacy system maintenance and existing inventory utilization.

All substitute parts maintain compliance with ROHS3 regulations, identical MSL ratings, and equivalent fault protection architectures, ensuring functional interchangeability within the specified electrical and thermal operating parameters.

Frequently Asked Questions (FAQ)

Q: Can TLE7243SLFUMA1 be used as a direct replacement for TLE7243SLXUMA2?

A: Yes. TLE7243SLFUMA1 is a parametric equivalent with identical electrical specifications (260mA output current, 1.2Ohm on-resistance, 1:2 ratio, 8 outputs, SPI interface, Low Side N-Channel configuration). Both parts use the same 24-SSOP package footprint and maintain equivalent operating ranges. The primary difference is product status: TLE7243SLFUMA1 is Active while TLE7243SLXUMA2 is Obsolete.

Q: What is the difference between TLE7244SLXUMA2 and TLE8108EMXUMA1?

A: Both parts offer improved performance over the original TLE7243SLXUMA2. TLE7244SLXUMA2 provides 290mA output current and 800mOhm on-resistance in the standard 24-SSOP package but is marked "Not For New Designs." TLE8108EMXUMA1 delivers higher current capability (400mA) with the same 800mOhm on-resistance and uses an updated 24-LSSOP package with exposed pad, with Active product status and significantly higher inventory availability.

Q: Are there package compatibility considerations when substituting these parts?

A: TLE7243SLXUMA2, TLE7244SLXUMA2, and TLE7243SLFUMA1 all use the 24-SSOP package with identical 0.154" width and 3.90mm dimensions, ensuring direct PCB footprint compatibility. TLE8108EMXUMA1 uses 24-LSSOP packaging with an exposed pad, which requires PCB layout modifications to accommodate the additional thermal pad connection. Verify PCB design compatibility before selecting TLE8108EMXUMA1.

Q: Which substitute part should be selected for new product designs?

A: TLE7243SLFUMA1 is recommended for new designs requiring specifications identical to the original TLE7243SLXUMA2, as it maintains all electrical parameters while offering Active product status and assured long-term availability. TLE8108EMXUMA1 is the alternative for applications benefiting from increased output current (400mA) and improved on-resistance performance, provided PCB layout can accommodate the 24-LSSOP package variant.

Q: Do all substitute parts maintain the same fault protection features?

A: Yes. All substitute parts—TLE7244SLXUMA2, TLE8108EMXUMA1, and TLE7243SLFUMA1—include identical fault protection: Open Load Detect and Over Temperature monitoring. Operating temperature ranges remain -40°C to 150°C (TJ) across all variants.

Q: What is the significance of the exposed pad in TLE8108EMXUMA1?

A: The exposed pad in the 24-LSSOP package provides enhanced thermal dissipation compared to the standard 24-SSOP variant. This thermal improvement supports the higher 400mA output current rating. PCB design must include appropriate thermal via patterns connected to ground or a thermal plane to realize this benefit.
