MIC2981/82BWM Equivalent & Substitute Parts

Part Overview

The MIC2981/82BWM is a power switch/driver IC from Microchip Technology designed for general-purpose bipolar switching applications. This component features 8 outputs with a 1:1 input-to-output ratio, high-side output configuration, and a maximum output current of 500mA. It operates across a load voltage range of 5V to 50V and is housed in an 18-SOP (Wide) package.

The MIC2981/82BWM is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC2981/82BWM is determined by strict alignment with the following critical parameters:

• Electrical Specifications: Number of outputs (8), input-to-output ratio (1:1), output configuration (high side), output type (bipolar), interface type (on/off), load voltage range (5 ~ 50V), maximum output current (500mA), and input type (non-inverting)
• Package Compatibility: 18-SOIC (0.295", 7.50mm Width) surface mount package
• Operating Conditions: Temperature range of -40°C to 85°C
• Manufacturer Consistency: Microchip Technology

The MIC2981/82YWM meets all substitution criteria as a direct equivalent from the same manufacturer with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MIC2981/82YWM is the direct substitute for the discontinued MIC2981/82BWM. Both parts are manufactured by Microchip Technology and share identical electrical and mechanical specifications across all critical parameters.

The MIC2981/82YWM offers additional advantages:

• Product Status: Active and currently available, ensuring supply chain continuity
• Regulatory Compliance: ROHS3 compliant, meeting current environmental standards
• Inventory Availability: 14,499 pieces in stock compared to the discontinued status of the original part

The difference in Moisture Sensitivity Level (MSL 1 versus MSL 2) reflects standard manufacturing variations and does not affect functional compatibility or performance in typical operating environments.

Frequently Asked Questions (FAQ)

Q: Can the MIC2981/82YWM be used as a direct replacement for the MIC2981/82BWM?

A: Yes. Both parts are identical in electrical specifications, output configuration, current rating, voltage range, package type, and operating temperature. The MIC2981/82YWM is the active equivalent.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and compliance certifications. The MIC2981/82YWM is currently active with ROHS3 compliance, while the MIC2981/82BWM is discontinued and RoHS non-compliant.

Q: Are there any package compatibility concerns?

A: No. Both parts use the identical 18-SOIC (0.295", 7.50mm Width) surface mount package. PCB layouts and footprints are fully compatible.

Q: What does the MSL rating difference mean?

A: MSL 1 (Unlimited) indicates the original part has no moisture sensitivity restrictions. MSL 2 (1 Year) for the substitute indicates standard moisture sensitivity with a one-year shelf life under controlled conditions. This does not affect functional performance.

Q: Is the MIC2981/82YWM suitable for new designs?

A: Yes. As the active product from Microchip Technology with current compliance certifications, it is the appropriate choice for new designs and production applications.
