MIC384-1YMM Equivalent & Substitute Parts

Part Overview

The MIC384-1YMM is an active digital temperature sensor manufactured by Microchip Technology, designed for local and remote temperature monitoring applications. This sensor operates across an extended temperature range of -55°C to 125°C with 7-bit resolution and communicates via I2C/SMBus interface. The device is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications, mechanical compatibility, and operational parameters align with the original component requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC384-1YMM are identified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

• Identical sensor type classification (Digital, Local/Remote)
• Matching temperature sensing range (-55°C ~ 125°C for both local and remote channels)
• Identical communication protocol (I2C/SMBus)
• Matching supply voltage specification (2.7V ~ 5.5V)
• Identical resolution (7 bits)
• Equivalent accuracy specifications (±2°C / ±3°C across defined test conditions)
• Compatible package format (8-MSOP surface mount)
• Matching feature set (Output Switch, Programmable Limit, Shutdown Mode, Standby Mode)

The MIC284-0YMM meets all these criteria and is classified as a manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the MIC384-1YMM and MIC284-0YMM are active production components from Microchip Technology with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on:

• Availability and lead time requirements
• Packaging format preference (both support 8-MSOP surface mount)
• Supply chain and inventory considerations
• Compliance requirements (both meet ROHS3 and REACH standards)
• Regulatory classification needs (both carry EAR99 designation)

The MIC284-0YMM is designated as the manufacturer-recommended substitute and maintains full functional equivalence with the MIC384-1YMM across all specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the MIC284-0YMM be used as a direct replacement for the MIC384-1YMM?

A: Yes. Both devices share identical electrical specifications, temperature sensing ranges, communication protocols, supply voltage requirements, resolution, accuracy ratings, and feature sets. The 8-MSOP surface mount package is compatible between both parts.

Q: Are there differences in the package or mounting requirements?

A: No. Both the MIC384-1YMM and MIC284-0YMM use the same 8-MSOP package format with 0.118" width (3.00mm). Surface mount assembly processes and PCB footprints are identical.

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

A: The part numbers reflect different manufacturing batches or packaging configurations. The MIC284-0YMM is supplied in tube packaging, while the MIC384-1YMM may have different packaging specifications. All functional and electrical parameters remain equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MIC384-1YMM and MIC284-0YMM are ROHS3 compliant, REACH unaffected, and classified under EAR99 export control designation.

Q: What temperature range do these sensors support?

A: Both sensors support -55°C to 125°C for local temperature sensing and -55°C to 125°C for remote temperature sensing, with accuracy of ±2°C across 0°C to 100°C and ±3°C across the full -55°C to 125°C range.

Q: Are the I2C/SMBus interfaces identical?

A: Yes. Both devices use identical I2C/SMBus communication protocols with matching programmable limits, output switch functionality, shutdown mode, and standby mode capabilities.
