Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC863YM8 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Dual-channel general-purpose operational amplifier architecture
• Rail-to-rail output configuration
• Slew rate of 0.35 V/µs
• Gain bandwidth product of 450 kHz
• -3dB bandwidth of 800 kHz
• Input bias current of 10 pA
• Input offset voltage of 100 µV
• Supply current of 4.2 µA per channel pair
• Output current capability of 27 mA per channel
• Supply voltage range: 2V to 5.25V minimum to maximum
• Operating temperature range: -40°C to 85°C

Mechanical & Compliance Equivalence Criteria:

• SOT-23-8 surface mount package
• ROHS3 compliance
• Moisture sensitivity level 1 (unlimited)

The substitute part MIC863YM8-TR maintains identical electrical specifications and differs only in packaging format (Tape & Reel versus standard packaging), making it a direct functional equivalent for component selection purposes.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution: MIC863YM8-TR is a direct functional equivalent to MIC863YM8. The sole difference is packaging format: MIC863YM8-TR is supplied in Tape & Reel configuration, while MIC863YM8 is supplied in standard packaging. Both parts maintain identical electrical specifications, mechanical dimensions (SOT-23-8), and compliance certifications (ROHS3, MSL 1).

Compliance & Regulatory Status: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Moisture sensitivity level 1 (unlimited) indicates no special storage or handling requirements beyond standard component practices.

Inventory & Availability: MIC863YM8-TR currently maintains higher inventory availability (9985 Pcs) compared to MIC863YM8 (6100 Pcs), making it the preferred selection for procurement continuity given the obsolete product status of both variants.

Frequently Asked Questions (FAQ)

Q: Can MIC863YM8-TR be used as a direct replacement for MIC863YM8?

A: Yes. MIC863YM8-TR is electrically and mechanically identical to MIC863YM8. The only difference is the packaging format (Tape & Reel versus standard packaging). Both parts are pin-compatible, have identical electrical performance, and fit the same PCB footprint.

Q: What does "Tape & Reel (TR)" packaging mean?

A: Tape & Reel packaging is an automated assembly format where components are supplied wound on a continuous carrier tape within a reel. This format is standard for high-volume manufacturing and automated pick-and-place assembly. Standard packaging typically refers to tube or tray formats used for lower-volume applications or manual assembly.

Q: Are there any thermal or electrical performance differences between MIC863YM8 and MIC863YM8-TR?

A: No. Both parts have identical electrical specifications, thermal characteristics, and operating parameters. The packaging format does not affect device performance.

Q: Why is the MIC863YM8 marked as obsolete?

A: Product obsolescence is determined by the manufacturer and typically reflects end-of-life status. MIC863YM8-TR shares the same obsolete status. For new designs requiring equivalent functionality, alternative general-purpose dual operational amplifiers with matching electrical specifications should be evaluated.

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

A: Substitution compatibility is determined by: dual-channel architecture, general-purpose amplifier type, rail-to-rail output, 0.35 V/µs slew rate, 450 kHz gain bandwidth product, 800 kHz -3dB bandwidth, 10 pA input bias current, 100 µV input offset voltage, 4.2 µA supply current per channel, 27 mA output current per channel, 2V to 5.25V supply range, -40°C to 85°C operating temperature, and SOT-23-8 surface mount package.

Q: Is the SOT-23-8 package footprint identical between both parts?

A: Yes. Both MIC863YM8 and MIC863YM8-TR use the SOT-23-8 package with identical pin configuration, spacing, and PCB footprint. No layout modifications are required for substitution.

Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Standard component storage practices are sufficient.
