Key Parameters

Substitute Part Grouping Explanation

Substitution of the THS4021CDGNG4 is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Amplifier topology (Voltage Feedback)
• Number of circuits (1)
• Slew rate (470 V/µs)
• Bandwidth (-3dB at 350 MHz)
• Input bias current (3 µA)
• Input offset voltage (500 µV)
• Supply current (7.8 mA)
• Output current capability (100 mA per channel)
• Supply voltage range (9 V to 32 V)

Mechanical & Environmental Criteria:

• Package type (8-HVSSOP with exposed pad)
• Mounting technology (Surface Mount)
• Operating temperature range (0°C to 70°C)
• Compliance certifications (ROHS3, MSL Level 1)

The THS4021CDGN shares identical electrical specifications and mechanical packaging with the THS4021CDGNG4. The primary distinction is packaging format (Tube versus Tape & Reel) and product status (Active versus Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The THS4021CDGN is a direct functional equivalent to the THS4021CDGNG4 for all electrical and mechanical applications. Both devices are manufactured by Texas Instruments and share identical performance specifications across all measured parameters.

Selection Basis:

The THS4021CDGN is recommended as the primary substitute because:

1. Product Status: The THS4021CDGN maintains Active status with Texas Instruments, ensuring continued availability and long-term supply chain support. The THS4021CDGNG4 is discontinued at DiGi Electronics.

2. Electrical Equivalence: All electrical parameters are identical, including bandwidth, slew rate, supply current, output current, and input characteristics.

3. Mechanical Compatibility: Both devices use the 8-HVSSOP package with exposed pad in surface mount configuration, ensuring PCB layout and thermal management compatibility.

4. Compliance Alignment: Both parts maintain ROHS3 compliance and MSL Level 1 rating, meeting environmental and reliability requirements.

5. Packaging Consideration: The THS4021CDGN is supplied in Tube packaging, while the THS4021CDGNG4 was supplied in Tape & Reel format. This difference affects handling and automated assembly processes but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the THS4021CDGN be used as a direct replacement for the THS4021CDGNG4 in existing designs?

A: Yes. The THS4021CDGN is electrically and mechanically equivalent to the THS4021CDGNG4. All electrical specifications, package dimensions, and pin configurations are identical. No circuit modifications are required.

Q: What is the difference between the THS4021CDGNG4 and THS4021CDGN?

A: The primary difference is packaging format. The THS4021CDGNG4 was supplied in Tape & Reel format, while the THS4021CDGN is supplied in Tube format. Additionally, the THS4021CDGN maintains Active product status, whereas the THS4021CDGNG4 is discontinued at DiGi Electronics. Electrical and mechanical specifications are identical.

Q: Are there any thermal or performance differences between these parts?

A: No. Both devices share identical thermal characteristics, operating temperature range (0°C to 70°C), and electrical performance specifications. The 8-HVSSOP package with exposed pad provides equivalent thermal management in both variants.

Q: Does the Tube packaging of the THS4021CDGN affect compatibility with automated assembly equipment?

A: Tube packaging requires different handling than Tape & Reel format. Automated pick-and-place equipment designed for Tape & Reel may require reconfiguration or manual feeding for Tube-packaged components. Verify equipment compatibility with your assembly partner before production transition.

Q: Are both parts RoHS compliant?

A: Yes. Both the THS4021CDGNG4 and THS4021CDGN are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, meeting environmental and regulatory requirements.

Q: What is the recommended lead time for sourcing the THS4021CDGN?

A: Lead time information is not provided in the technical specifications. Contact your authorized Texas Instruments distributor for current availability and delivery schedules.
