Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCP6051-E/SN are identified based on the following critical parameters that determine functional and mechanical compatibility:

Mechanical Compatibility:

• Package type: 8-SOIC surface mount
• Package dimensions: 0.154" × 3.90mm width
• Mounting type: Surface mount

Electrical Compatibility Envelope:

• Output type: Rail-to-rail configuration
• Number of circuits: Single circuit
• Supply voltage range: Minimum 1.8 V to maximum 6 V (substitute must operate within or encompass this range)
• Operating temperature: -40°C to 125°C
• Amplifier category: General purpose or voltage feedback

Regulatory & Compliance:

• RoHS3 compliance
• MSL rating: 1 (Unlimited)
• REACH unaffected status

The identified substitute parts meet these criteria while maintaining functional equivalence for general purpose amplification applications.

Engineering Selection Recommendations

AD8061ARZ Series (Analog Devices Inc.)

The AD8061ARZ, AD8061ARZ-REEL, and AD8061ARZ-REEL7 are voltage feedback amplifiers with identical electrical specifications but different packaging formats. All three variants are ROHS3 compliant, MSL 1 rated, and in active production status. These parts operate within an extended supply voltage range (2.7 V to 8 V) that encompasses the MCP6051-E/SN operating envelope. The primary trade-off is higher supply current (6.8 mA versus 30 µA) and higher input bias current (3.5 µA versus 1 pA), offset by significantly higher slew rate (650 V/µs versus 0.15 V/µs) and bandwidth performance. Selection among the three variants depends on packaging requirements: AD8061ARZ for tube packaging, AD8061ARZ-REEL for tape and reel, and AD8061ARZ-REEL7 for cut tape and Digi-Reel format.

TS507IDT (STMicroelectronics)

The TS507IDT is a general purpose amplifier in tape and reel packaging with ROHS3 compliance and MSL 1 rating. This part operates across 2.7 V to 5.5 V supply range, which overlaps the MCP6051-E/SN range but with a lower maximum voltage limit. The TS507IDT exhibits higher supply current (850 µA) and higher input bias current (8 nA) compared to the MCP6051-E/SN, but maintains the same operating temperature range (-40°C to 125°C). The slew rate (0.6 V/µs) and gain bandwidth product (1.9 MHz) are intermediate between the MCP6051-E/SN and AD8061ARZ series.

All substitute parts maintain mechanical compatibility through identical 8-SOIC packaging and surface mount mounting type, ensuring direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can AD8061ARZ series parts directly replace MCP6051-E/SN in all applications?

A: AD8061ARZ series parts are mechanically compatible (identical 8-SOIC package) and electrically compatible within the overlapping supply voltage range (2.7 V to 6 V). However, the higher supply current (6.8 mA versus 30 µA) and input bias current (3.5 µA versus 1 pA) may affect circuit performance in applications requiring ultra-low power consumption or extremely low input bias current. The significantly higher slew rate (650 V/µs) and bandwidth (320 MHz) provide superior dynamic performance.

Q: What is the difference between AD8061ARZ, AD8061ARZ-REEL, and AD8061ARZ-REEL7?

A: These three part numbers are electrically identical with the same specifications. The differences are in packaging format: AD8061ARZ is supplied in tube packaging, AD8061ARZ-REEL in tape and reel format, and AD8061ARZ-REEL7 in cut tape and Digi-Reel format. Selection depends on assembly process requirements and inventory management preferences.

Q: Is TS507IDT suitable for applications requiring operation below 2.7 V?

A: No. The TS507IDT minimum supply voltage is 2.7 V, which exceeds the MCP6051-E/SN minimum of 1.8 V. Applications requiring operation at 1.8 V to 2.6 V supply voltage cannot use TS507IDT as a substitute.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts (AD8061ARZ, AD8061ARZ-REEL, AD8061ARZ-REEL7, and TS507IDT) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the MCP6051-E/SN compliance profile.

Q: Which substitute part has the lowest power consumption?

A: The MCP6051-E/SN has the lowest supply current at 30 µA. Among the substitutes, TS507IDT has the lowest supply current at 850 µA, followed by AD8061ARZ series at 6.8 mA. For ultra-low power applications, the MCP6051-E/SN remains the optimal choice.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, all parts use identical 8-SOIC surface mount packaging with 0.154" width and 3.90mm dimensions, enabling direct PCB layout compatibility without redesign. Pin assignments and functional pinout are standard for single-circuit operational amplifiers in this package type.

Q: What is the operating temperature range difference between substitutes?

A: The MCP6051-E/SN and TS507IDT both operate across -40°C to 125°C. The AD8061ARZ series (all three variants) operates across -40°C to 85°C, providing a narrower upper temperature limit. Applications requiring operation above 85°C must use MCP6051-E/SN or TS507IDT.
