TLV9034DYYR Equivalent & Substitute Parts

Part Overview

The TLV9034DYYR is a high-performance quad low-voltage comparator manufactured by Texas Instruments, designed for general-purpose applications requiring rail-to-rail push-pull output capability. This device operates across a supply voltage range of 1.65V to 5.5V and is housed in a 14-pin SOT-23 thin package for surface mount applications. The part is currently in active production status with 3693 units available in new original inventory. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required for design flexibility, supply chain continuity, or application-specific certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV9034DYYR is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Supply voltage range (1.65V ~ 5.5V), input offset voltage (1.5mV @ 5V), input bias current (5pA @ 5V), output current (100mA @ 5V), quiescent current (30µA), CMRR/PSRR characteristics (70dB CMRR, 95dB PSRR), and propagation delay (100ns Typ)
• Functional Architecture: Quad configuration with four independent general-purpose comparator elements
• Output Characteristics: Push-pull, rail-to-rail output topology
• Mechanical Compatibility: SOT-23-14 thin package, surface mount configuration
• Environmental & Compliance: Operating temperature range (-40°C ~ 125°C), RoHS3 compliance, MSL 1 rating, REACH unaffected status

The TLV9034QDYYRQ1 meets all these criteria while adding automotive-grade qualification (AEC-Q100), making it suitable for applications requiring enhanced reliability and traceability in automotive environments.

Parameter Comparison

Engineering Selection Recommendations

Both the TLV9034DYYR and TLV9034QDYYRQ1 are active production devices with identical electrical specifications and mechanical packaging. Selection between these parts is determined by application requirements:

TLV9034DYYR is appropriate for commercial and industrial applications where standard RoHS3 compliance and general-purpose performance are sufficient.

TLV9034QDYYRQ1 is specified for automotive applications requiring AEC-Q100 qualification, which provides enhanced manufacturing process controls, reliability testing, and traceability documentation mandated by automotive supply chain standards.

Both parts maintain identical performance across all provided electrical parameters, supply voltage range, temperature operating range, and package configuration. The distinction is qualification level and intended market segment, not functional capability.

Frequently Asked Questions (FAQ)

Q: Can TLV9034QDYYRQ1 be used as a direct replacement for TLV9034DYYR in commercial applications?

A: Yes. The TLV9034QDYYRQ1 meets or exceeds all electrical and mechanical specifications of the TLV9034DYYR. The automotive qualification adds process rigor but does not restrict use in non-automotive applications.

Q: Can TLV9034DYYR be used in automotive applications?

A: TLV9034DYYR lacks AEC-Q100 qualification. Automotive applications requiring certified component traceability and qualification documentation must use TLV9034QDYYRQ1.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the SOT-23-14 thin package variant with identical mechanical specifications, pin configuration, and surface mount footprint.

Q: What is the significance of the "Q1" designation in TLV9034QDYYRQ1?

A: The "Q1" suffix indicates AEC-Q100 automotive qualification, signifying compliance with automotive reliability and testing standards.

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

A: No. Both parts provide identical electrical performance across all specified parameters: supply voltage range, input offset voltage, bias current, output current, quiescent current, CMRR/PSRR, propagation delay, and operating temperature range.

Q: What is the inventory status for both parts?

A: TLV9034DYYR has 3693 units in new original stock. TLV9034QDYYRQ1 has 3678 units in new original stock.

Q: Are both parts RoHS3 compliant?

A: Yes. Both TLV9034DYYR and TLV9034QDYYRQ1 are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.
