Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC5842BWM is determined by strict equivalence across the following critical parameters:

• Switch Type & Output Configuration: Latched Driver with Low Side, Bipolar output
• Channel Architecture: 1:8 input-to-output ratio with 8 total outputs
• Interface Protocol: Strobe and Serial control compatibility
• Electrical Ratings: Maximum load voltage of 15V and 500mA output current capacity
• Input Logic: Non-Inverting input type
• Thermal Range: Operating temperature range of -55°C to 85°C
• Physical Form Factor: 18-SOIC (0.295", 7.50mm Width) surface mount package

The MIC5842YWM qualifies as a direct substitute based on identical electrical specifications, output architecture, and package form factor. The primary distinction lies in product status and compliance certifications rather than functional or electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The MIC5842YWM is a direct functional equivalent to the MIC5842BWM with identical electrical specifications and package form factor. Selection between these parts should be based on the following criteria:

MIC5842YWM (Recommended for New Designs): This part is currently in active product status with ROHS3 compliance certification. It is suitable for applications requiring regulatory compliance with modern environmental standards and long-term supply chain availability.

MIC5842BWM (Legacy/Existing Inventory): This part is discontinued at DiGi Electronics and carries RoHS non-compliant status. It may be retained for legacy system maintenance or existing inventory applications where compliance requirements do not apply.

Both parts share identical functional performance, electrical ratings, and physical packaging, ensuring direct interchangeability at the circuit board level.

Frequently Asked Questions (FAQ)

Q: Can the MIC5842YWM replace the MIC5842BWM in existing designs?

A: Yes. The MIC5842YWM is electrically and functionally identical to the MIC5842BWM. All electrical parameters, output architecture, interface protocols, and package dimensions are equivalent. Direct substitution is possible without circuit modification.

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

A: The primary differences are product status and compliance certification. The MIC5842BWM is discontinued and RoHS non-compliant, while the MIC5842YWM is active and ROHS3 compliant. Electrical specifications and packaging are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 18-SOIC (0.295", 7.50mm Width) surface mount package with identical pinout and mechanical dimensions.

Q: Which part should be selected for new production designs?

A: The MIC5842YWM should be selected for new designs due to its active product status and ROHS3 compliance certification, ensuring regulatory compliance and supply chain continuity.

Q: Is the MIC5842YWM available in different packaging options?

A: The MIC5842YWM is supplied in Tube packaging, while the MIC5842BWM packaging type is not specified. Both maintain the same 18-SOIC form factor suitable for surface mount assembly.
