Substitute Part Grouping Explanation

Substitution of the THS3110CDG4 is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Amplifier Type: Current Feedback architecture
• Slew Rate: 1300 V/µs
• Bandwidth (-3dB): 100 MHz
• Input Bias Current: 1.5 µA
• Input Offset Voltage: 3 mV
• Supply Current: 4.8 mA
• Output Current per Channel: 260 mA
• Supply Voltage Range: 10 V to 30 V

Physical & Environmental Criteria:

• Package Type: 8-SOIC surface mount
• Package Dimensions: 0.154" width (3.90mm)
• Moisture Sensitivity: MSL 1 (Unlimited)
• RoHS Compliance: ROHS3 Compliant
• REACH Status: REACH Unaffected

The THS3110ID qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

THS3110ID as Primary Substitute:

The THS3110ID is a direct functional and physical equivalent to the THS3110CDG4. All electrical performance parameters, package specifications, and compliance certifications are identical. The THS3110ID maintains Active product status with Texas Instruments, ensuring ongoing availability and technical support.

The THS3110ID features an extended operating temperature range (-40°C to 85°C) compared to the THS3110CDG4 (0°C to 70°C). This extended range provides additional thermal margin for applications operating in wider environmental conditions.

Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for commercial and industrial applications. Moisture Sensitivity Level 1 (Unlimited) indicates no special handling requirements during storage or assembly.

The THS3110ID is supplied in Tube packaging, whereas the THS3110CDG4 packaging type was not specified. Surface mount assembly processes are compatible with both parts due to identical 8-SOIC package geometry.

Frequently Asked Questions (FAQ)

Q: Can the THS3110ID directly replace the THS3110CDG4 in existing designs?

A: Yes. The THS3110ID is electrically and mechanically equivalent. All performance parameters, supply voltage requirements, output current ratings, and bandwidth specifications are identical. The 8-SOIC package footprint is the same, enabling direct PCB substitution without layout modifications.

Q: What is the significance of the different operating temperature ranges?

A: The THS3110CDG4 operates from 0°C to 70°C, while the THS3110ID operates from -40°C to 85°C. The THS3110ID provides a wider thermal operating window. For applications constrained to 0°C to 70°C, both parts are functionally equivalent. For applications requiring extended temperature performance, the THS3110ID is the appropriate selection.

Q: Why is the THS3110CDG4 marked as Obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued active production and support for this specific part number variant. The THS3110ID, carrying Active status, represents the current production equivalent and is the recommended selection for new designs and ongoing production requirements.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the THS3110CDG4 and THS3110ID maintain identical RoHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 classification. Regulatory and environmental compliance requirements are satisfied by either part.

Q: What is the difference between the CDG4 and ID suffixes?

A: The suffix designates the packaging and temperature grade variant. CDG4 indicates a specific packaging configuration with 0°C to 70°C temperature rating. ID indicates the Active production variant with -40°C to 85°C temperature rating. Both use the same 8-SOIC package footprint.

Q: Is the THS3110ID available in the same quantities as the THS3110CDG4?

A: Current inventory status shows 1061 pieces of THS3110ID available as New Original stock, compared to 885 pieces of THS3110CDG4. The THS3110ID, being an Active product, typically maintains more consistent availability through distribution channels.

Q: Can I use the THS3110ID in applications originally designed for the THS3110CDG4?

A: Yes, without modification. Electrical performance, package footprint, pin configuration, and functional behavior are identical. The extended temperature range of the THS3110ID provides additional operational margin without introducing any compatibility issues.
