Substitute Part Grouping Explanation

Substitution of the MIC7300BMM-TR is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Equivalence Requirements:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Slew Rate: 0.5 V/µs
• Gain Bandwidth Product: 370 kHz
• Current - Input Bias: 0.5 pA
• Voltage - Input Offset: 1 mV
• Current - Supply: 1.5 mA
• Current - Output / Channel: 115 mA
• Voltage - Supply Span: 2.2V to 10V
• Operating Temperature: -40°C to 85°C

Mechanical Equivalence Requirements:

• Package / Case: 8-MSOP (0.118", 3.00mm Width)
• Mounting Type: Surface Mount
• Series: MM8™

The MIC7300YMM-TR meets all electrical and mechanical equivalence criteria and is classified as a direct substitute for the discontinued MIC7300BMM-TR.

Parameter Comparison

Engineering Selection Recommendations

The MIC7300YMM-TR is the direct substitute for the discontinued MIC7300BMM-TR. Both devices are manufactured by Microchip Technology and share identical electrical specifications and mechanical packaging.

Availability and Product Status: The MIC7300BMM-TR is discontinued at DiGi Electronics with no ongoing production. The MIC7300YMM-TR maintains active product status with current inventory of 2168 pieces available, ensuring supply chain continuity for new designs and production requirements.

Compliance Considerations: The MIC7300YMM-TR provides improved regulatory compliance as a ROHS3-compliant device, compared to the RoHS non-compliant status of the original MIC7300BMM-TR. Both devices maintain REACH Unaffected and EAR99 ECCN classifications. The moisture sensitivity level (MSL 1 - Unlimited) is identical across both parts.

Direct Substitution: All electrical parameters, mechanical dimensions, and functional characteristics are identical. The 8-MSOP package footprint and surface-mount configuration remain unchanged, enabling direct PCB-level substitution without design modification.
