Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS2048ADRG4 is determined by compatibility across the following critical parameters:

Mechanical Compatibility: Package type (16-SOIC), mounting type (Surface Mount), and physical dimensions (0.154", 3.90mm Width) must match to ensure PCB layout compatibility without redesign.

Electrical Compatibility: Output configuration (High Side), output type (N-Channel), number of outputs (4), voltage load range (2.7V ~ 5.5V), and fault protection features (Current Limiting, Over Temperature, UVLO) establish functional equivalence.

Substitutes are categorized as follows:

Parametric Equivalent: TPS2048ADR maintains identical electrical specifications (1:1 ratio, 250mA, 80mOhm Rds On, Inverting input) with different packaging (Cut Tape vs. Tape & Reel). This part is functionally interchangeable at the circuit level.

Manufacturer Recommended Substitutes: LM3544M-L/NOPB and LM3544MX-L/NOPB provide enhanced specifications (1:2 ratio, 500mA output current, 90mOhm Rds On, Non-Inverting input, Status Flag feature) within the same package footprint. These parts support higher current applications and extended temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent): TPS2048ADR is the primary parametric equivalent, maintaining identical electrical specifications and fault protection architecture. This part is recommended when the original 1:1 input-to-output ratio, 250mA current rating, and Inverting input logic are required. The part is currently Active in product status and ROHS3 Compliant.

For Enhanced Performance Applications: LM3544MX-L/NOPB is recommended when higher output current capacity (500mA) and extended temperature range (-40°C ~ 85°C) are required within the same Tape & Reel packaging format. The 1:2 input-to-output ratio and Non-Inverting input logic require circuit-level evaluation. This part is currently Active and ROHS3 Compliant.

For Tube Packaging Requirements: LM3544M-L/NOPB provides identical electrical specifications to LM3544MX-L/NOPB with Tube packaging and extended operating temperature range (-40°C ~ 125°C). This part is currently Active and ROHS3 Compliant.

All substitute parts maintain compliance with ROHS3 and REACH requirements, ensuring regulatory continuity.

Frequently Asked Questions (FAQ)

Q: Can TPS2048ADR be used as a direct drop-in replacement for TPS2048ADRG4?

A: Yes. TPS2048ADR is a parametric equivalent with identical electrical specifications (1:1 ratio, 250mA output current, 80mOhm Rds On, Inverting input) and package footprint (16-SOIC). The primary difference is packaging format (Cut Tape vs. Tape & Reel). Circuit-level compatibility is maintained.

Q: What are the key differences between TPS2048ADRG4 and LM3544MX-L/NOPB?

A: The LM3544MX-L/NOPB features a 1:2 input-to-output ratio (vs. 1:1), higher output current (500mA vs. 250mA), Non-Inverting input logic (vs. Inverting), and includes a Status Flag feature. Operating temperature range is -40°C ~ 85°C (vs. 0°C ~ 85°C). These differences require circuit-level evaluation before substitution.

Q: Are all substitute parts available in the same 16-SOIC package?

A: Yes. All substitute parts (TPS2048ADR, LM3544M-L/NOPB, LM3544MX-L/NOPB) use the 16-SOIC package with identical physical dimensions (0.154", 3.90mm Width), ensuring PCB layout compatibility without redesign.

Q: What is the difference between LM3544M-L/NOPB and LM3544MX-L/NOPB?

A: Both parts have identical electrical specifications. The primary differences are packaging format (Tube vs. Tape & Reel) and operating temperature range (LM3544M-L/NOPB: -40°C ~ 125°C; LM3544MX-L/NOPB: -40°C ~ 85°C). Select based on packaging requirements and temperature operating conditions.

Q: Do all parts meet RoHS and REACH compliance?

A: Yes. All parts listed (TPS2048ADRG4, TPS2048ADR, LM3544M-L/NOPB, LM3544MX-L/NOPB) are ROHS3 Compliant and REACH Unaffected.

Q: What fault protection features are included in these parts?

A: All parts include Current Limiting (Fixed), Over Temperature protection, and UVLO (Under Voltage Lock Out). These features are consistent across all substitute options.
