Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2721CDBVT is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute part, TLV2721CDBVR, maintains identical specifications across all critical performance characteristics: amplifier type, circuit count, output configuration, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, supply voltage range, and operating temperature range. Both parts share the same base product number (TLV2721), series designation (LinCMOS™), package type (SOT-23-5), and compliance certifications (ROHS3, REACH Unaffected).

The substitution is valid based on the following key parameters:

• Identical electrical performance specifications
• Matching package and pinout configuration (SOT-23-5)
• Equivalent supply voltage operating range (2.7 V to 10 V)
• Identical output current capability (50 mA per channel)
• Matching thermal and environmental specifications
• Equivalent compliance and regulatory status

Electrical and Mechanical Equivalence: All specified electrical parameters, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current capability, are identical. The package configuration (SOT-23-5) and pinout are identical, enabling direct board-level substitution without design modification.

Inventory and Procurement: The TLV2721CDBVR demonstrates significantly higher inventory availability (10,520 pieces) compared to the original part, supporting production continuity and reducing procurement lead time.

Frequently Asked Questions (FAQ)

Q: Can TLV2721CDBVR be used as a direct replacement for TLV2721CDBVT in existing designs?

A: Yes. The TLV2721CDBVR is electrically and mechanically equivalent to the TLV2721CDBVT. All performance specifications, package configuration, and pinout are identical. No circuit design changes or board layout modifications are required.

Q: What is the difference between TLV2721CDBVT and TLV2721CDBVR?

A: The parts are functionally identical. The primary difference is product status: TLV2721CDBVT is Last Time Buy (discontinued), while TLV2721CDBVR is Active (current production). The suffix designation indicates different packaging or distribution channels, but electrical performance and package type remain unchanged.

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

A: No. Both parts operate across the identical temperature range (0°C to 70°C) and maintain equivalent thermal characteristics. Moisture sensitivity level is identical (MSL 1, Unlimited).

Q: Do both parts meet the same compliance standards?

A: Yes. Both TLV2721CDBVT and TLV2721CDBVR are ROHS3 Compliant and REACH Unaffected. No additional compliance verification is required when substituting between these parts.

Q: What is the SOT-23-5 package specification?

A: SOT-23-5 (also designated SC-74A or SOT-753) is a surface-mount integrated circuit package with five leads. This package is standard for single-channel operational amplifiers and is widely used in low-power analog applications. Pin spacing and footprint are identical between both parts.

Q: Can the TLV2721CDBVR handle the same supply voltage range as the original part?

A: Yes. Both parts operate across the identical supply voltage range of 2.7 V to 10 V. Output current capability (50 mA per channel) and supply current consumption (110 µA) are also identical.

Q: Is there any performance degradation when using the substitute part?

A: No. The TLV2721CDBVR maintains identical electrical performance specifications: slew rate (0.25 V/µs), gain bandwidth product (510 kHz), input bias current (1 pA), input offset voltage (500 µV), and output current capability (50 mA). No performance degradation occurs.
