MIC2182BM Equivalent & Substitute Parts

Part Overview

The MIC2182BM is a buck regulator positive output step-down DC-DC controller IC manufactured by Microchip Technology in a 16-SOIC package. This component functions as a transistor driver for step-down voltage conversion applications with a single output phase. The MIC2182BM is currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain identical electrical specifications, package configuration, and functional characteristics to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC2182BM are qualified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain identical:

• Topology: Buck (step-down)
• Output Type: Transistor Driver
• Output Configuration: Positive
• Number of Outputs: 1
• Output Phases: 1
• Voltage Supply Range: 4.5V ~ 32V
• Switching Frequency: 300kHz
• Duty Cycle (Max): 86%
• Synchronous Rectifier: Yes
• Clock Sync: Yes
• Control Features: Enable, Soft Start
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• MSL: 1 (Unlimited)

All substitute parts listed maintain these specifications without deviation. Substitutes are differentiated only by product status and compliance certifications, not by functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both MIC2182YM and MIC2182-5.0YM are direct functional equivalents to the MIC2182BM with identical electrical and mechanical specifications. The primary differentiators are product status and regulatory compliance.

MIC2182YM is the preferred substitute for applications requiring active product support and ROHS3 compliance. This part maintains full availability and is actively manufactured by Microchip Technology.

MIC2182-5.0YM is an alternative substitute also offering ROHS3 compliance and active product status. Both substitute parts are electrically and mechanically interchangeable with the MIC2182BM in all applications where the original part was specified.

For new designs or production continuity, either MIC2182YM or MIC2182-5.0YM should be selected based on inventory availability and supply chain requirements. Both parts eliminate the risk associated with the discontinued MIC2182BM status.

Frequently Asked Questions (FAQ)

Q: Can MIC2182YM or MIC2182-5.0YM be used as direct replacements for MIC2182BM?

A: Yes. Both parts are direct functional equivalents with identical electrical specifications, output configuration, switching frequency, duty cycle, control features, and 16-SOIC package. No circuit modifications are required.

Q: What is the difference between MIC2182YM and MIC2182-5.0YM?

A: Both parts are electrically and mechanically identical. The difference in part number designation reflects internal Microchip Technology product line organization. Both are ROHS3 compliant and actively manufactured.

Q: Why is the MIC2182BM discontinued?

A: The MIC2182BM is discontinued at DiGi Electronics. MIC2182YM and MIC2182-5.0YM remain in active production and are the recommended alternatives for ongoing supply.

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

A: Yes. The MIC2182BM is RoHS non-compliant, while both MIC2182YM and MIC2182-5.0YM are ROHS3 compliant. All three parts maintain REACH Unaffected status.

Q: Will the substitute parts work in existing PCB designs without layout changes?

A: Yes. The 16-SOIC package dimensions, pin configuration, and mounting type are identical across all three parts. Existing PCB layouts require no modification.

Q: What is the supply voltage range for these parts?

A: All three parts operate with a supply voltage range of 4.5V to 32V, supporting a wide range of input voltage applications.

Q: Are the control features identical across all three parts?

A: Yes. Enable and Soft Start control features are identical on MIC2182BM, MIC2182YM, and MIC2182-5.0YM.
