Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC281-0BM6-TR is determined by the following critical parameters:

• Sensor type classification (Digital, Remote)
• Output communication protocol (I2C/SMBus)
• Remote sensing temperature range (-55°C ~ 125°C)
• Resolution (7 bits)
• Supply voltage range (3V ~ 3.6V)
• Accuracy specifications (±3°C / ±5°C)
• Physical package (SOT-23-6)
• Mounting configuration (Surface Mount)
• Functional features (Shutdown Mode)

The MIC281-0YM6-TR qualifies as a direct substitute because it maintains identical electrical specifications, mechanical packaging, and functional characteristics across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The MIC281-0YM6-TR is the direct substitute for the discontinued MIC281-0BM6-TR. Both components share identical electrical and mechanical specifications, ensuring pin-compatible and functionally equivalent operation.

The MIC281-0YM6-TR offers the additional advantage of active product status and ROHS3 compliance, making it the preferred selection for new designs and production applications. The MIC281-0BM6-TR's RoHS non-compliant status further supports transition to the MIC281-0YM6-TR for regulatory and supply chain continuity.

Current inventory availability of 4983 pieces for the MIC281-0YM6-TR supports immediate procurement for both prototype and volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can the MIC281-0YM6-TR be used as a direct replacement for the MIC281-0BM6-TR?

A: Yes. Both components are electrically and mechanically identical. The MIC281-0YM6-TR maintains the same I2C/SMBus interface, 7-bit resolution, ±3°C accuracy, SOT-23-6 package, and -55°C to 125°C operating range. Pin-for-pin substitution is supported without circuit modification.

Q: What are the key parameters that define substitution compatibility?

A: Substitution compatibility is determined by: sensor type (Digital, Remote), output protocol (I2C/SMBus), remote sensing temperature range (-55°C ~ 125°C), resolution (7 bits), supply voltage (3V ~ 3.6V), accuracy specifications (±3°C / ±5°C), SOT-23-6 package, surface mount configuration, and Shutdown Mode feature.

Q: Does the MIC281-0YM6-TR require any PCB layout changes?

A: No. The MIC281-0YM6-TR uses the identical SOT-23-6 package and pinout as the MIC281-0BM6-TR. Existing PCB layouts and footprints require no modification.

Q: What is the difference between the MIC281-0BM6-TR and MIC281-0YM6-TR?

A: The primary differences are product status and regulatory compliance. The MIC281-0BM6-TR is discontinued and RoHS non-compliant, while the MIC281-0YM6-TR is active and ROHS3 compliant. All functional and electrical parameters are identical.

Q: Are there any supply voltage or temperature range limitations when substituting?

A: No. Both components operate across the identical supply voltage range (3V ~ 3.6V) and temperature range (-55°C ~ 125°C). No application-level adjustments are required.
