Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2451IDBVR is determined by strict equivalence across the following critical parameters:

Functional Equivalence Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C to 125°C

Electrical Performance Boundaries:

• Supply voltage range must encompass or be contained within 2.7 V to 6 V
• Slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current must be within acceptable design margins for the application
• Package compatibility: SOT-23-5 or equivalent 5-pin surface mount packages

The NCS20091SN2T1G from onsemi meets these substitution criteria as a single-circuit, rail-to-rail general-purpose amplifier in a compatible 5-TSOP (SOT-23-5 Thin) package with active product status and identical compliance certifications.

Engineering Selection Recommendations

TLV2451IDBVR (Primary Selection):

• Active product status with high inventory availability (235,095 pcs)
• ROHS3 compliant and REACH unaffected
• Established supply chain through Texas Instruments
• Suitable for applications requiring the specified electrical performance envelope

NCS20091SN2T1G (Substitute Selection):

• Active product status with available inventory (17,236 pcs)
• ROHS3 compliant and REACH unaffected
• Compatible package footprint (5-TSOP / SOT-23-5 Thin)
• Enhanced electrical performance characteristics: higher slew rate (0.15 V/µs vs 0.11 V/µs), higher gain bandwidth product (350 kHz vs 220 kHz), and lower input bias current (1 pA vs 500 pA)
• Reduced output current capability (8.5 mA vs 10 mA) and narrower supply voltage range (1.8 V to 5.5 V vs 2.7 V to 6 V) require circuit design verification

Both parts carry identical compliance certifications and moisture sensitivity ratings, supporting direct substitution within the specified parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can NCS20091SN2T1G replace TLV2451IDBVR in all applications?

A: Substitution is valid when the circuit design operates within the NCS20091SN2T1G parameter envelope. The substitute part has a narrower minimum supply voltage (1.8 V vs 2.7 V) and maximum supply voltage (5.5 V vs 6 V). Verify that your supply voltage range falls within 1.8 V to 5.5 V. Additionally, the output current is reduced from 10 mA to 8.5 mA; confirm that load requirements do not exceed 8.5 mA per channel.

Q: Are the package dimensions identical between TLV2451IDBVR and NCS20091SN2T1G?

A: Both parts use 5-pin surface mount packages in the SOT-23 family. TLV2451IDBVR uses SC-74A/SOT-753 packaging, while NCS20091SN2T1G uses SOT-23-5 Thin (TSOT-23-5). These packages are mechanically compatible for PCB footprint purposes, though dimensional specifications should be verified against manufacturer datasheets for high-precision applications.

Q: What are the key electrical differences between these parts?

A: The NCS20091SN2T1G demonstrates superior dynamic performance with 36% higher slew rate (0.15 V/µs vs 0.11 V/µs) and 59% higher gain bandwidth product (350 kHz vs 220 kHz). Input bias current is significantly lower (1 pA vs 500 pA). However, output current capability is 15% lower (8.5 mA vs 10 mA), and input offset voltage is higher (500 µV vs 300 µV). Supply current remains identical at 23 µA.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TLV2451IDBVR and NCS20091SN2T1G are ROHS3 compliant, REACH unaffected, carry MSL rating of 1 (Unlimited), and share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -40°C to 125°C, supporting applications in industrial and automotive environments within this specification.
