Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC2077-2BWM TR is determined by strict equivalence across the following critical parameters:

• Switch Type: USB Switch
• Number of Outputs: 4
• Ratio - Input:Output: 2 x 1:2
• Output Type: N-Channel
• Output Configuration: High Side
• Voltage - Load: 2.7V ~ 5.5V
• Current - Output (Max): 500mA
• Rds On (Typ): 100mOhm
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount
• Features: Slew Rate Controlled, Status Flag
• Fault Protection: Current Limiting (Fixed), Over Temperature, UVLO

All identified substitutes maintain identical electrical and mechanical specifications. Differences exist only in packaging format (Tape & Reel vs. Tube), product status (Active vs. Obsolete), and compliance certifications (RoHS3 Compliant vs. RoHS non-compliant).

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete MIC2077-2BWM TR, the following active alternatives are available:

Primary Recommendation: MIC2077-2YWM-TR

This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The Tape & Reel packaging format aligns with the original component's distribution method, facilitating direct integration into existing production workflows.

Secondary Recommendation: MIC2077-2YWM

Functionally equivalent to the primary recommendation with identical electrical performance. The Tube packaging format differs from the original Tape & Reel specification and may require process adjustments for automated assembly operations.

Alternative Options: MIC2077-1YWM-TR, MIC2027-1YWM-TR, MIC2027-2YWM-TR

All three alternatives maintain complete electrical and mechanical equivalence. Selection among these options depends on inventory availability and specific procurement requirements. The MIC2027 series represents a parametric equivalent from an alternative product line within the Microchip Technology portfolio.

All substitute parts carry ROHS3 compliance certification, addressing regulatory requirements that may not have been applicable to the original obsolete component.

Frequently Asked Questions (FAQ)

Q: Can MIC2077-2YWM-TR be used as a direct replacement for MIC2077-2BWM TR?

A: Yes. Both components share identical electrical specifications, including 500mA output current, 100mOhm typical on-resistance, 2.7V to 5.5V load voltage range, and 16-SOIC package dimensions. The primary difference is product status (Active vs. Obsolete) and RoHS compliance certification.

Q: What is the difference between MIC2077-2YWM and MIC2077-2YWM-TR?

A: Both parts are electrically and mechanically identical. The difference is packaging format: MIC2077-2YWM is supplied in Tube packaging, while MIC2077-2YWM-TR is supplied in Tape & Reel format. Selection depends on assembly process requirements and inventory handling procedures.

Q: Are MIC2027-1YWM-TR and MIC2027-2YWM-TR suitable substitutes?

A: Yes. These components are parametric equivalents with identical electrical performance across all critical parameters: 500mA output current, 100mOhm on-resistance, 2.7V to 5.5V load voltage, and 16-SOIC package. They represent an alternative product line within Microchip Technology's USB Switch portfolio.

Q: Does the change from RoHS non-compliant to ROHS3 compliant affect circuit operation?

A: No. RoHS compliance status reflects manufacturing process restrictions on hazardous substances and does not alter electrical performance or functional behavior. All substitute parts maintain identical circuit-level specifications.

Q: Can I mix packaging formats (Tape & Reel and Tube) in production?

A: Packaging format selection should align with your assembly equipment and process specifications. While electrically identical, Tape & Reel and Tube formats require different handling and feeding mechanisms in automated assembly operations.

Q: What is the significance of the Moisture Sensitivity Level (MSL) change from 1 to 2?

A: MSL 1 indicates unlimited shelf life without moisture control. MSL 2 requires storage in controlled humidity conditions with a 1-year shelf life limit. This affects component storage and handling procedures but does not impact electrical performance or circuit operation.
