Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV3701CDBVTG4 is determined by the following critical parameters:

• Output configuration: CMOS, push-pull, rail-to-rail output
• Single-channel comparator topology
• Supply voltage compatibility: 2.5V ~ 16V single supply or ±1.25V ~ 8V dual supply
• Input offset voltage specification: 5mV maximum at 15V
• Input bias current: 250pA maximum at 15V
• Output current capability: 10mA typical
• Quiescent current: 1µA maximum
• Common-mode rejection ratio and power supply rejection ratio: 88dB CMRR and 105dB PSRR
• SOT-23-5 surface mount package
• ROHS3 compliance and MSL Level 1 rating

The TLV3701IDBVR is classified as a manufacturer-recommended substitute with active product status and extended operating temperature range (-40°C ~ 125°C). The TLV3701CDBVR is a parametric equivalent with last-time-buy status and identical electrical specifications to the main part.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications requiring the TLV3701CDBVTG4, the TLV3701IDBVR is the primary substitute. This part maintains identical electrical specifications while offering active product status and extended operating temperature range (-40°C ~ 125°C versus 0°C ~ 70°C). The wider temperature range provides greater design flexibility for industrial and automotive applications.

The TLV3701CDBVR serves as a parametric equivalent with identical electrical characteristics to the main part. However, its last-time-buy status indicates limited future availability, making it suitable only for legacy production support or short-term requirements.

Both substitute parts maintain full ROHS3 compliance, MSL Level 1 rating, and identical packaging specifications (SOT-23-5), ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can TLV3701IDBVR replace TLV3701CDBVTG4 in existing designs?

A: Yes. The TLV3701IDBVR is electrically equivalent with identical input offset voltage, bias current, output current, and frequency response characteristics. The extended operating temperature range (-40°C ~ 125°C) provides additional margin for temperature-sensitive applications. Direct substitution is possible without circuit modifications.

Q: What is the difference between TLV3701IDBVR and TLV3701CDBVR?

A: Both parts are parametrically equivalent to the main part with identical electrical specifications. The primary difference is product status: TLV3701IDBVR is active with extended temperature range, while TLV3701CDBVR is last-time-buy with the original temperature range (0°C ~ 70°C). For new designs, TLV3701IDBVR is recommended.

Q: Are there packaging differences between these parts?

A: No. All three parts use identical SOT-23-5 surface mount packaging (SC-74A, SOT-753). PCB footprints and assembly processes remain unchanged.

Q: What supply voltage range is supported?

A: All parts support 2.5V to 16V single supply or ±1.25V to ±8V dual supply operation. The TLV3701IDBVR supports a slightly higher minimum single supply voltage (2.7V) and dual supply voltage (±1.35V), which is compatible with designs using the original part.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant with MSL Level 1 (unlimited moisture sensitivity), suitable for standard PCB assembly and storage conditions.
