Engineering Selection Recommendations

MCP661-E/SN (Microchip Technology)

The MCP661-E/SN is an active product with ROHS3 compliance and REACH unaffected status. This device offers superior gain bandwidth product (60 MHz versus 33 MHz) and significantly lower supply current (6 µA versus 505 µA), making it suitable for power-sensitive applications. The extended operating temperature range (-40°C to 125°C) provides broader environmental coverage than the CLC1008ISO8MTR. Slew rate of 32V/µs remains within acceptable performance parameters for general purpose amplification. Input bias current specification of 6 pA represents improved precision characteristics. Packaging is supplied in Tube format with 2228 units in stock inventory.

TSV991AIYDT (STMicroelectronics)

The TSV991AIYDT is an active product with automotive qualification (AEC-Q100) and ROHS3 compliance. This device features the lowest input bias current (1 pA) among available substitutes and the highest output current capability (35 mA versus 15 mA), supporting higher load-driving applications. Extended operating temperature range (-40°C to 125°C) and automotive-grade qualification provide enhanced reliability for demanding environments. Slew rate of 10V/µs and gain bandwidth product of 20 MHz represent lower performance specifications compared to the CLC1008ISO8MTR, requiring evaluation for bandwidth-critical applications. Packaging is supplied in Tape & Reel format with 6216 units in stock inventory.

Frequently Asked Questions (FAQ)

Q: Can MCP661-E/SN directly replace CLC1008ISO8MTR in existing designs?

A: Direct replacement is mechanically feasible due to identical 8-SOIC package geometry. Electrical compatibility exists across the specified supply voltage range (2.5V to 5.5V) and operating temperature overlap (-40°C to 85°C). The MCP661-E/SN offers superior performance specifications including higher gain bandwidth product (60 MHz) and lower supply current (6 µA). Circuit validation is required to confirm performance adequacy for specific application requirements.

Q: What are the key differences between MCP661-E/SN and TSV991AIYDT?

A: MCP661-E/SN prioritizes low power consumption (6 µA supply current) and high bandwidth (60 MHz gain bandwidth product), suitable for battery-powered and signal processing applications. TSV991AIYDT emphasizes output current capability (35 mA) and precision input characteristics (1 pA bias current), with automotive qualification for harsh environment deployment. Slew rate differs significantly: MCP661-E/SN at 32V/µs versus TSV991AIYDT at 10V/µs.

Q: Is the CLC1008ISO8MTR operating temperature range a limiting factor for substitution?

A: The CLC1008ISO8MTR operates from -40°C to 85°C. Both substitute parts extend this range to -40°C to 125°C, providing additional thermal margin. Applications limited to the original -40°C to 85°C specification are fully compatible with either substitute. Applications requiring operation above 85°C benefit from the extended range of substitute devices.

Q: What packaging formats are available for substitute parts?

A: MCP661-E/SN is supplied in Tube packaging format. TSV991AIYDT is supplied in Tape & Reel (TR) format. Both maintain the identical 8-SOIC (0.154", 3.90mm Width) package geometry, ensuring PCB footprint compatibility. Packaging format selection depends on production volume and assembly equipment compatibility.

Q: Are substitute parts RoHS and REACH compliant?

A: Both MCP661-E/SN and TSV991AIYDT are ROHS3 compliant. MCP661-E/SN is REACH unaffected. TSV991AIYDT is REACH unaffected. The original CLC1008ISO8MTR compliance status is not specified in available documentation.

Q: Which substitute part is recommended for power-constrained applications?

A: MCP661-E/SN is recommended for power-constrained applications, featuring supply current of 6 µA compared to 505 µA for the CLC1008ISO8MTR and 820 µA for TSV991AIYDT. This represents approximately 84-fold reduction in quiescent current consumption.

Q: Which substitute part is recommended for high output current applications?

A: TSV991AIYDT is recommended for applications requiring higher output current capability, providing 35 mA per channel versus 15 mA for the CLC1008ISO8MTR. This device is suitable for driving moderate impedance loads directly from the amplifier output.
