Engineering Selection Recommendations

Active Product Availability: All identified substitute parts maintain active product status with major manufacturers, ensuring long-term availability, technical support, and supply chain continuity. The CLC2000ISO8 obsolete status necessitates transition to one of these active alternatives.

Compliance and Certifications: Substitute parts LMH6622MA/NOPB, LMH6626MA/NOPB, LMH6655MA/NOPB, LT1816CS8#PBF, OPA2652U/2K5, and OPA2889ID all carry ROHS3 compliance certification, meeting environmental and regulatory requirements for modern electronics manufacturing. LMH6628MA/NOPB from National Semiconductor does not specify RoHS status in provided data.

Supply Voltage Compatibility: All substitute parts operate within or exceed the 5V to 12V supply range of the CLC2000ISO8. LMH6655MA/NOPB, LT1816CS8#PBF, and OPA2889ID support lower minimum voltages (4.5V, 2.5V, and 2.6V respectively), providing additional design flexibility. LT1816CS8#PBF operates to 11V maximum, requiring verification for 12V applications.

Operating Temperature Range: LMH6626MA/NOPB extends the upper operating temperature to 125°C, suitable for elevated-temperature environments. LT1816CS8#PBF operates only to 70°C maximum, restricting use to commercial temperature range applications. All other substitutes match or exceed the -40°C to 85°C specification.

Output Drive Capability: The CLC2000ISO8 delivers 1A per channel output current. Substitute parts provide reduced output current (60mA to 140mA per channel), except OPA2652U/2K5 which delivers 140mA. Applications requiring the full 1A output capability require circuit redesign or external output buffering.

Power Consumption: OPA2889ID demonstrates significantly lower supply current (0.92mA total for 2 channels) compared to the CLC2000ISO8 (6.75mA), offering power efficiency advantages. LMH6622MA/NOPB (4.3mA) and LMH6655MA/NOPB (4.5mA) also provide reduced power consumption.

Frequency Response: OPA2652U/2K5 provides the highest -3dB bandwidth (700MHz), exceeding the CLC2000ISO8 (510MHz). LMH6628MA/NOPB (300MHz) and LT1816CS8#PBF (350MHz) also exceed the baseline. LMH6622MA/NOPB (160MHz) and LMH6626MA/NOPB (95MHz) provide reduced bandwidth suitable for lower-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can the CLC2000ISO8 be directly replaced with any of these substitute parts without PCB modification?

A: Yes, all substitute parts use identical 8-SOIC (0.154", 3.90mm Width) surface mount packaging, enabling direct PCB footprint compatibility without layout changes. However, electrical performance differences may require circuit parameter adjustment or validation testing.

Q: Which substitute part most closely matches the CLC2000ISO8 electrical performance?

A: LMH6655MA/NOPB provides the closest match in slew rate (200V/µs versus 210V/µs), supply current (4.5mA versus 6.75mA), and operating temperature range (-40°C to 85°C). This part is recommended for applications requiring minimal design modification.

Q: What is the primary limitation when substituting for the CLC2000ISO8?

A: Output current capability is the primary constraint. The CLC2000ISO8 delivers 1A per channel, while all substitute parts provide 60mA to 140mA per channel. Applications requiring high output current must incorporate external output buffering or redesign the output stage.

Q: Are all substitute parts RoHS3 compliant?

A: Seven of eight substitute parts carry explicit ROHS3 compliance certification (LMH6622MA/NOPB, LMH6626MA/NOPB, LMH6655MA/NOPB, LT1816CS8#PBF, OPA2652U/2K5, OPA2889ID). LMH6628MA/NOPB does not specify RoHS status in available documentation.

Q: Which substitute part operates at the lowest supply voltage?

A: LT1816CS8#PBF supports operation down to 2.5V minimum supply voltage, followed by OPA2889ID (2.6V) and LMH6655MA/NOPB (4.5V). The CLC2000ISO8 requires minimum 5V. Lower-voltage operation enables single-cell battery applications.

Q: Can the LT1816CS8#PBF be used in applications requiring 12V supply operation?

A: No. LT1816CS8#PBF maximum supply voltage is 11V, making it unsuitable for 12V supply systems. All other substitute parts support the full 5V to 12V range.

Q: Which substitute part provides the best power efficiency?

A: OPA2889ID consumes only 0.92mA total supply current (0.46mA per channel), representing 86% reduction compared to the CLC2000ISO8 (6.75mA). This part is optimal for battery-powered or power-constrained applications.

Q: What is the temperature operating range limitation for LT1816CS8#PBF?

A: LT1816CS8#PBF operates from 0°C to 70°C, restricting use to commercial temperature range. The CLC2000ISO8 and most substitute parts operate from -40°C to 85°C. LMH6626MA/NOPB extends to 125°C for industrial and high-temperature applications.

Q: Are there packaging format differences among the substitute parts?

A: All substitute parts use 8-SOIC surface mount packaging with identical footprint dimensions (0.154", 3.90mm Width). Packaging formats (Tube, Tape & Reel, Bulk) differ only in quantity and shipping configuration, not in component form factor.

Q: Which substitute part provides the highest slew rate?

A: LT1816CS8#PBF delivers 1500V/µs slew rate, nearly 7 times the CLC2000ISO8 specification (210V/µs). LMH6628MA/NOPB (550V/µs) and LMH6626MA/NOPB (400V/µs) also provide significantly higher slew rates for fast signal applications.
