MIC2075-2FBM Equivalent & Substitute Parts

Part Overview

The MIC2075-2FBM is a Power Switch/Driver IC manufactured by Microchip Technology, designed for general-purpose N-channel high-side switching applications. This 8-SOIC surface-mount component delivers 500mA output current with integrated current limiting, over-temperature protection, and under-voltage lockout (UVLO) fault protection. The device operates across a 2.7V to 5.5V load voltage range with a typical on-resistance of 90mOhm.

The MIC2075-2FBM has been discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement. Substitute parts must maintain electrical compatibility across switching characteristics, output current ratings, voltage specifications, and fault protection features.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC2075-2FBM are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — ensures PCB layout compatibility
• Output Configuration: High Side, N-Channel — maintains circuit topology
• Number of Outputs: 1 — functional equivalence
• Ratio - Input:Output: 1:1 — signal path integrity
• Voltage - Load: 2.7V ~ 5.5V — operating range compatibility
• Current - Output (Max): 500mA — load handling capability
• Fault Protection: Current Limiting (Fixed), Over Temperature, UVLO — protection feature parity
• Operating Temperature: -40°C ~ 85°C (TA) — thermal operating range

Acceptable Variation:

• Rds On (Typ): Substitute parts with lower on-resistance (70mOhm vs. 90mOhm) provide improved performance without functional incompatibility
• Input Type: Inverting input (TPS2041 series) versus Non-Inverting input (MIC2075-2FBM) requires circuit-level verification but does not preclude substitution in applications where input logic is adapted

The TPS2041BD and TPS2041BDR from Texas Instruments meet all critical electrical and mechanical substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

TPS2041BD (Tube Packaging)

The TPS2041BD is an active, ROHS3-compliant substitute offering identical electrical specifications to the MIC2075-2FBM with improved on-resistance performance (70mOhm vs. 90mOhm). This part is suitable for applications requiring tube packaging and lower unit volumes. Current inventory availability is 2600 pieces.

TPS2041BDR (Cut Tape & Digi-Reel Packaging)

The TPS2041BDR is an active, ROHS3-compliant substitute with the same electrical performance as TPS2041BD, differentiated by Cut Tape and Digi-Reel packaging. This configuration supports high-volume production and automated assembly processes. Current inventory availability is 20400 pieces, providing superior supply chain continuity.

Both TPS2041 variants provide regulatory compliance advantages over the discontinued MIC2075-2FBM through ROHS3 certification and active product status, ensuring long-term availability and design support.

Frequently Asked Questions (FAQ)

Q: Can TPS2041BD and TPS2041BDR be used interchangeably with MIC2075-2FBM?

A: Both TPS2041 variants meet all critical electrical and mechanical substitution parameters: identical package (8-SOIC), output configuration (high-side N-channel), voltage range (2.7V–5.5V), current rating (500mA), and fault protection features (current limiting, over-temperature, UVLO). The primary difference is packaging format (tube vs. cut tape/reel). Circuit-level verification is required to confirm input logic compatibility, as TPS2041 uses inverting input logic compared to the non-inverting input of MIC2075-2FBM.

Q: What is the difference between TPS2041BD and TPS2041BDR?

A: Both parts are electrically identical with the same 70mOhm typical on-resistance and performance characteristics. The distinction is packaging: TPS2041BD is supplied in tube packaging for lower-volume applications, while TPS2041BDR uses Cut Tape and Digi-Reel packaging optimized for high-volume automated assembly. Selection depends on production volume and assembly equipment compatibility.

Q: Does the lower on-resistance of TPS2041 (70mOhm vs. 90mOhm) affect circuit design?

A: Lower on-resistance reduces power dissipation and heat generation during switching operation, providing a performance improvement. No circuit redesign is required; the TPS2041 operates within the same voltage and current specifications as the MIC2075-2FBM. Thermal performance will be enhanced.

Q: Are there compliance or regulatory differences between MIC2075-2FBM and TPS2041 substitutes?

A: Yes. The MIC2075-2FBM is RoHS non-compliant, while both TPS2041BD and TPS2041BDR are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the TPS2041 variants provide regulatory alignment. Both parts share identical REACH and ECCN classifications.

Q: What is the impact of input logic inversion on circuit implementation?

A: The MIC2075-2FBM features non-inverting input logic, while TPS2041 variants use inverting input logic. This requires verification at the circuit level to confirm that the control signal source can accommodate the inverted logic requirement. Consult device datasheets for detailed input threshold specifications and timing characteristics before final design implementation.
