MIC2548-2BM-TR Equivalent & Substitute Parts

Part Overview

The MIC2548-2BM-TR is a Power Switch/Driver IC from Microchip Technology, classified as a Power Management (PMIC) component. This N-Channel high-side switch is designed for USB switching applications with 1:1 input-to-output ratio and 1.5A maximum output current. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts maintain identical electrical and mechanical specifications while offering improved availability and compliance status.

Substitute Part Grouping Explanation

Substitution for the MIC2548-2BM-TR is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitutes:

Critical Matching Parameters:

• Switch Type: USB Switch
• Number of Outputs: 1
• Ratio - Input:Output: 1:1
• Output Configuration: High Side
• Output Type: N-Channel
• Interface: On/Off
• Voltage - Load: 2.7V ~ 5.5V
• Current - Output (Max): 1.5A
• Rds On (Typ): 80mOhm
• Input Type: Non-Inverting
• Features: Status Flag
• Fault Protection: Current Limiting (Adjustable), Over Temperature
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)

All three substitute parts—MIC2544-1YM-TR, MIC2544-2YM-TR, and MIC2544A-1YM-TR—meet these criteria. Differences exist only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and product status (Active versus Discontinued).

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts provide complete electrical and mechanical equivalence to the MIC2548-2BM-TR. Selection among substitutes should be based on the following factors:

Product Status: The MIC2548-2BM-TR is discontinued at DiGi Electronics. All substitute parts (MIC2544-1YM-TR, MIC2544-2YM-TR, MIC2544A-1YM-TR) maintain Active product status, ensuring long-term availability and supply chain continuity.

Compliance: The original MIC2548-2BM-TR is RoHS non-compliant. All three substitute parts are ROHS3 Compliant, meeting current regulatory requirements for new designs and manufacturing. All parts maintain REACH Unaffected status.

Packaging Format: MIC2544-1YM-TR and MIC2544-2YM-TR are supplied in Cut Tape (CT) & Digi-Reel® format. MIC2544A-1YM-TR is supplied in Tape & Reel (TR) format. Packaging selection depends on assembly line requirements and order quantities.

Inventory Availability: MIC2544-2YM-TR offers the highest inventory level (2400 Pcs), followed by MIC2544A-1YM-TR (1843 Pcs) and MIC2544-1YM-TR (1674 Pcs).

Frequently Asked Questions (FAQ)

Q: Are the MIC2544 series parts direct replacements for the MIC2548-2BM-TR?

A: Yes. The MIC2544-1YM-TR, MIC2544-2YM-TR, and MIC2544A-1YM-TR are parametric equivalents with identical electrical specifications, output characteristics, protection features, and 8-SOIC package dimensions. They function as direct substitutes in all applications where the MIC2548-2BM-TR was specified.

Q: What is the difference between MIC2544-1YM-TR, MIC2544-2YM-TR, and MIC2544A-1YM-TR?

A: The primary differences are packaging format and inventory availability. MIC2544-1YM-TR and MIC2544-2YM-TR use Cut Tape & Digi-Reel® packaging, while MIC2544A-1YM-TR uses Tape & Reel packaging. All three are electrically identical and ROHS3 Compliant. Selection depends on assembly requirements and supply needs.

Q: Why is the MIC2548-2BM-TR discontinued?

A: The original part is RoHS non-compliant. Microchip Technology has transitioned to the MIC2544 series, which maintains identical functionality while meeting ROHS3 compliance requirements.

Q: Can I use these substitutes in existing designs without PCB modifications?

A: Yes. All substitute parts use the same 8-SOIC (0.154", 3.90mm Width) package footprint as the MIC2548-2BM-TR. No PCB layout changes are required for direct substitution.

Q: Are there any electrical performance differences between the original and substitute parts?

A: No. All parts share identical electrical specifications: 1.5A maximum output current, 80mOhm typical on-resistance, 2.7V to 5.5V load voltage range, -40°C to 85°C operating temperature, and identical fault protection features (adjustable current limiting and over-temperature protection).

Q: Which substitute should I select for new production?

A: For new production, any of the three MIC2544 series parts is suitable. MIC2544-2YM-TR is recommended for high-volume orders due to superior inventory availability. For specific packaging requirements, select based on assembly line compatibility: Cut Tape & Digi-Reel® for standard pick-and-place operations, or Tape & Reel for specialized handling systems.
