Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2221CDBVT is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Slew Rate: 0.18 V/µs
• Gain Bandwidth Product: 510 kHz
• Current - Input Bias: 1 pA
• Voltage - Input Offset: 610 µV
• Current - Supply: 110 µA
• Current - Output / Channel: 50 mA
• Voltage - Supply Span: 2.7 V to 10 V

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: SC-74A, SOT-753
• Supplier Device Package: SOT-23-5

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The TLV2221IDBVR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is the operating temperature range and product status, which do not affect functional substitution in applications within the overlapping temperature window.

Parameter Comparison

Engineering Selection Recommendations

The TLV2221IDBVR is a direct functional equivalent to the TLV2221CDBVT for applications operating within the temperature range of 0°C to 70°C. Both devices are manufactured by Texas Instruments and share identical electrical specifications, package configuration, and compliance certifications.

Selection Basis:

The TLV2221IDBVR is designated as Active product status, ensuring continued availability and manufacturing support from Texas Instruments. This addresses the Last Time Buy status of the TLV2221CDBVT and provides long-term supply chain stability.

Both parts maintain ROHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited), satisfying regulatory and environmental requirements for industrial and commercial applications.

The TLV2221IDBVR offers an extended operating temperature range (-40°C to 85°C) compared to the TLV2221CDBVT (0°C to 70°C). For applications requiring operation only within 0°C to 70°C, both devices are functionally interchangeable. For applications requiring extended low-temperature operation below 0°C or high-temperature operation above 70°C, the TLV2221IDBVR provides additional thermal margin.

Packaging differences (Tape & Reel versus Cut Tape & Digi-Reel®) do not affect electrical performance and reflect only distribution and handling methods.

Frequently Asked Questions (FAQ)

Q: Can the TLV2221IDBVR be used as a direct replacement for the TLV2221CDBVT in existing designs?

A: Yes, the TLV2221IDBVR is a direct functional replacement for applications operating within the 0°C to 70°C temperature range. All electrical specifications, package dimensions, and pin configurations are identical. No circuit modifications are required.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel and Cut Tape & Digi-Reel® are distribution formats that do not affect component performance. Tape & Reel is supplied on continuous tape for automated assembly. Cut Tape & Digi-Reel® provides flexibility in order quantities. Both formats contain the same SOT-23-5 package.

Q: Why does the TLV2221IDBVR have a wider operating temperature range?

A: The TLV2221IDBVR is specified for -40°C to 85°C, while the TLV2221CDBVT is specified for 0°C to 70°C. This reflects different qualification and testing protocols. For applications within the overlapping range (0°C to 70°C), both devices perform identically.

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

A: No. Both the TLV2221CDBVT and TLV2221IDBVR are ROHS3 compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Regulatory and environmental compliance is identical.

Q: What is the significance of the Last Time Buy status for the TLV2221CDBVT?

A: Last Time Buy indicates that Texas Instruments has announced the end of production for this part number. Existing inventory will be depleted, and no new manufacturing runs are planned. The TLV2221IDBVR, designated as Active, ensures continued availability and is the recommended path for new designs and long-term supply requirements.

Q: Can the TLV2221IDBVR be used in applications requiring temperatures below 0°C or above 70°C?

A: The TLV2221IDBVR is specified for operation from -40°C to 85°C and can be used in applications requiring extended temperature ranges. The TLV2221CDBVT is specified only to 0°C to 70°C and should not be used outside this range.

Q: Are the electrical characteristics identical between TLV2221CDBVT and TLV2221IDBVR?

A: Yes. Both devices share identical specifications for slew rate (0.18 V/µs), gain bandwidth product (510 kHz), input bias current (1 pA), input offset voltage (610 µV), supply current (110 µA), and output current (50 mA). Supply voltage range is also identical (2.7 V to 10 V).

Q: What is the SOT-23-5 package, and is it the same as SC-74A and SOT-753?

A: SOT-23-5, SC-74A, and SOT-753 are equivalent designations for the same five-pin surface mount package. All three terms refer to the identical physical package used by both the TLV2221CDBVT and TLV2221IDBVR.
