Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV1391IDBVT is determined by strict equivalence across the following critical parameters:

• Differential comparator topology with single element configuration
• Open-collector output type
• Supply voltage range: 2V ~ 7V
• Input offset voltage: 5mV @ 5V maximum
• Input bias current: 0.25µA @ 5V maximum
• Output current: 20mA typical
• Quiescent current: 175µA maximum
• Operating temperature range: -40°C ~ 85°C
• Package type: SOT-23-5 (SC-74A, SOT-753)
• Surface mount mounting type
• ROHS3 compliance and REACH unaffected status

The TLV1391IDBVR meets all these parameters identically. The only difference between the main part and substitute is the packaging format: the main part uses Cut Tape (CT) while the substitute uses Tape & Reel (TR). Both are sourced from the same manufacturer and base product series.

Parameter Comparison

Engineering Selection Recommendations

The TLV1391IDBVR is the direct substitute for the TLV1391IDBVT. Both parts share identical electrical specifications, thermal characteristics, and compliance certifications. The primary distinction is product status: the main part is obsolete while the substitute is active, making the TLV1391IDBVR the appropriate choice for new designs and ongoing production requirements.

Packaging format differs between the two parts. The main part is supplied in Cut Tape format, while the substitute is supplied in Tape & Reel format. This distinction affects procurement and assembly processes but does not impact electrical performance or functional compatibility. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications requiring environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can TLV1391IDBVR replace TLV1391IDBVT in existing designs?

A: Yes. The TLV1391IDBVR provides complete functional equivalence. All electrical parameters, operating ranges, and package dimensions are identical. The only difference is packaging format and product status.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging supplies components in individual strips cut to specific lengths, suitable for smaller volume orders. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for high-volume automated assembly. Both formats contain the same component in the same SOT-23-5 package.

Q: Why is the main part listed as obsolete?

A: Product obsolescence indicates that Texas Instruments has discontinued active production and support for the TLV1391IDBVT. The TLV1391IDBVR remains active and is the recommended source for this comparator function.

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

A: No. Both parts operate identically across all specified parameters including supply voltage range, input offset voltage, bias current, output current, quiescent current, and operating temperature range.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TLV1391IDBVT and TLV1391IDBVR are ROHS3 compliant and REACH unaffected, meeting the same environmental and regulatory requirements.
