MIC280-2BM6-TR Equivalent & Substitute Parts

Part Overview

The MIC280-2BM6-TR is a supervisor sensor integrated circuit from Microchip Technology's IttyBitty™ series, designed for power management applications. This device functions as an open drain or open collector supervisor with active low reset capability, housed in a SOT-23-6 surface mount package. The MIC280-2BM6-TR is currently discontinued at DiGi Electronics, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC280-2BM6-TR is determined by strict equivalence across the following critical parameters:

• Voltage threshold specification (2.95V)
• Output configuration (Open Drain or Open Collector)
• Reset polarity (Active Low)
• Reset timeout duration (200µs Maximum)
• Operating temperature range (-55°C ~ 125°C)
• Package type (SOT-23-6)
• Mounting configuration (Surface Mount)
• Manufacturer (Microchip Technology)
• Series designation (IttyBitty™)

The MIC280-2YM6-TR meets all these criteria and qualifies as a direct functional equivalent. The primary distinction between these parts is product status and regulatory compliance, not electrical or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MIC280-2YM6-TR is the direct equivalent for the discontinued MIC280-2BM6-TR. Both parts share identical electrical specifications, package configuration, and thermal characteristics. The MIC280-2YM6-TR is currently in active production status with 746 units available in inventory.

For new designs or production restocking, the MIC280-2YM6-TR is the appropriate selection. This part maintains full functional compatibility while offering improved regulatory compliance through ROHS3 certification, whereas the original MIC280-2BM6-TR is RoHS non-compliant. Both parts maintain equivalent REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the MIC280-2YM6-TR directly replace the MIC280-2BM6-TR in existing designs?

A: Yes. The MIC280-2YM6-TR is electrically and mechanically identical to the MIC280-2BM6-TR. All critical parameters including voltage threshold, output configuration, reset polarity, reset timeout, operating temperature range, and package type are equivalent. No circuit modifications are required.

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

A: The primary differences are product status and RoHS compliance. The MIC280-2BM6-TR is discontinued and RoHS non-compliant, while the MIC280-2YM6-TR is in active production and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are the packages identical?

A: Yes. Both parts use the SOT-23-6 surface mount package with identical pinout and mechanical dimensions. No PCB layout changes are necessary.

Q: What is the inventory status for the substitute part?

A: The MIC280-2YM6-TR has 746 units available in new original stock.

Q: Do both parts have the same thermal characteristics?

A: Yes. Both parts operate across the identical temperature range of -55°C to 125°C (TA) and share the same Moisture Sensitivity Level (MSL) rating of 1 (Unlimited).
