Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Primary Substitution Criteria:

• Output Type: Push-Pull, Rail-to-Rail configuration
• Package / Case: 5-TSSOP, SC-70-5, SOT-353 (pin-compatible surface mount)
• Supply Voltage Range: Minimum 2.7V support required
• Operating Temperature: -40°C ~ 85°C range
• Propagation Delay: Maximum 20ns preferred for timing-critical applications
• Input Offset Voltage: Maximum 6mV @ 5V for precision applications

Parametric Equivalent Parts maintain identical electrical specifications and package compatibility, enabling direct substitution without circuit modification.

Manufacturer Recommended Alternatives offer comparable functionality with relaxed or enhanced specifications in specific parameters, suitable for applications where the LMV7219M7 specifications exceed requirements or where alternative packages are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent Selection (Direct Substitution):

LMV7219M7/NOPB and LMV7219M7X/NOPB are parametric equivalents with identical electrical specifications and SC-70-5 package compatibility. Both parts are Active status, ensuring long-term availability. LMV7219M7/NOPB carries higher inventory (25,200 pcs) compared to LMV7219M7X/NOPB (17,100 pcs), making it the preferred choice for immediate procurement. Both maintain ROHS3 compliance and MSL-1 rating.

Alternative Selection for Enhanced Supply Voltage Range:

MAX9075EXK+T extends the supply voltage range to 2.1V ~ 5.5V with improved input offset voltage (1mV @ 5V). This part is suitable for applications requiring lower supply voltage operation. However, propagation delay increases to 580ns, making it unsuitable for timing-critical applications requiring the original 20ns specification.

Alternative Selection for Extended Temperature or Low-Power Operation:

MAX9119EXK+T (Beyond-the-Rails™ series) offers extended supply range (1.6V ~ 5.5V) and reduced quiescent current (1.2µA), beneficial for battery-powered applications. Input offset voltage (5mV @ 5V) remains within acceptable tolerance. Propagation delay of 40µs indicates this part is optimized for low-power operation rather than high-speed switching.

Alternative Selection for Dual Supply Operation:

MAX985EXK+T and MAX987EXK+T support dual supply operation (±1.25V ~ 2.75V) in addition to single supply (2.5V ~ 5.5V). Both maintain SC-70-5 package compatibility. MAX987EXK+T offers faster propagation delay (210ns) compared to MAX985EXK+T (450ns), making it preferable for timing-sensitive circuits.

Package Variant Consideration:

MAX987EUK+T is functionally equivalent to MAX987EXK+T but uses SOT-23-5 package instead of SC-70-5. This part is suitable only if PCB layout accommodates the alternative package footprint.

Alternative with Different Package:

AZV3001FZ4-7 (Diodes Incorporated) uses 6-XFDFN package and is not pin-compatible with the SC-70-5 footprint. This part requires PCB redesign and is recommended only when package change is acceptable. It offers superior input offset voltage (0.5mV Typ) and lower quiescent current (6µA Typ).

STMicroelectronics Alternative:

TS3011ICT maintains SC-70-5 package compatibility and operates within 2.2V ~ 5V range. Limited parametric data availability (input offset voltage, propagation delay, and CMRR/PSRR not specified) requires datasheet verification before selection.

Frequently Asked Questions (FAQ)

Q: Can LMV7219M7/NOPB be used as a direct replacement for LMV7219M7?

A: Yes. LMV7219M7/NOPB is a parametric equivalent with identical electrical specifications, package, and operating temperature range. The primary difference is product status (Active vs. Last Time Buy) and REACH classification. Both are ROHS3 compliant with MSL-1 rating.

Q: What is the difference between LMV7219M7/NOPB and LMV7219M7X/NOPB?

A: Both parts are parametric equivalents with identical electrical specifications and SC-70-5 package. The "X" designation typically indicates extended temperature or manufacturing process variation. Electrical performance is equivalent for circuit design purposes.

Q: Can MAX987EXK+T replace LMV7219M7 in all applications?

A: MAX987EXK+T maintains SC-70-5 package compatibility and supports the 2.7V ~ 5V supply range of the original part. However, quiescent current increases from 1.8mA to 96µA, and propagation delay increases from 20ns to 210ns. Substitution is suitable only for applications where these parameter changes are acceptable.

Q: Why does AZV3001FZ4-7 require PCB redesign?

A: AZV3001FZ4-7 uses 6-XFDFN package instead of SC-70-5. The pinout and footprint are incompatible with existing PCB layouts designed for 5-TSSOP packages. PCB redesign is mandatory for this substitution.

Q: Which substitute part offers the lowest quiescent current?

A: AZV3001FZ4-7 offers the lowest quiescent current at 6µA (Typ), followed by MAX9075EXK+T at 6.6µA. However, AZV3001FZ4-7 requires package change and different pinout configuration.

Q: Is TS3011ICT suitable as a substitute when parametric data is incomplete?

A: TS3011ICT maintains SC-70-5 package compatibility and operates within 2.2V ~ 5V range. However, critical parameters including input offset voltage, propagation delay, CMRR, and PSRR are not specified in available data. Complete datasheet review is required before design implementation.

Q: Can MAX987EUK+T be used instead of MAX987EXK+T?

A: MAX987EUK+T uses SOT-23-5 package instead of SC-70-5. While electrical specifications are identical, the package footprint is incompatible with SC-70-5 PCB layouts. Substitution requires PCB redesign.

Q: What is the advantage of MAX9119EXK+T for battery-powered applications?

A: MAX9119EXK+T (Beyond-the-Rails™ series) combines extended supply voltage range (1.6V ~ 5.5V) with reduced quiescent current (1.2µA), making it suitable for low-power battery operation. Trade-off is increased propagation delay (40µs) compared to the original 20ns specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance. MSL ratings vary: LMV7219 variants and MAX parts carry MSL-1 (Unlimited), while AZV3001FZ4-7 carries MSL-3 (168 Hours), requiring controlled storage conditions.
