Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LMV7239M7 are categorized based on strict electrical and mechanical compatibility criteria. The primary substitution logic follows these parameters:

Parametric Equivalents maintain identical electrical specifications and package form factor (SC-70-5), differing only in packaging configuration (Cut Tape vs. Tape & Reel) or lead finish designation. These parts are direct functional replacements with no design modifications required.

Manufacturer-Recommended Alternatives are functionally equivalent comparators that meet or exceed the electrical performance of the LMV7239M7 while maintaining compatibility with the same application requirements. These parts may differ in package type, operating temperature range, or specific electrical characteristics, but remain suitable for general-purpose comparator applications within the specified voltage and performance envelope.

Substitution eligibility is determined by:

• Output type compatibility (Push-Pull)
• Supply voltage range overlap (minimum 2.7V ~ 5.5V coverage)
• Propagation delay performance (≤ 62ns preferred for timing-critical applications)
• Package form factor (SC-70-5 preferred; SOT-23-5 acceptable with PCB layout adjustment)
• Operating temperature range (-40°C ~ 85°C minimum)
• Surface mount capability

Parameter Comparison

Engineering Selection Recommendations

Direct Replacements (No Design Changes Required)

LMV7239M7/NOPB and LMV7239M7X/NOPB are parametric equivalents of the LMV7239M7, maintaining identical electrical performance and SC-70-5 package specifications. Both parts are ROHS3 compliant with MSL 1 rating. LMV7239M7X/NOPB offers higher inventory availability (20,100 units) compared to LMV7239M7/NOPB (3,350 units). Selection between these two should prioritize availability and lead time requirements.

Compatible Alternatives (Same Package, Verified Performance)

MCP6561T-E/LT (Microchip Technology) and TS3021ICT (STMicroelectronics) maintain the SC-70-5 package form factor with electrical specifications compatible to the LMV7239M7. MCP6561T-E/LT provides extended operating temperature range (-40°C ~ 125°C) and lower propagation delay (80ns). TS3021ICT offers superior CMRR performance (79dB) and extended temperature range. Both are ROHS3 compliant with active product status.

Package-Variant Alternatives (SOT-23-5 Form Factor)

TS3021ILT and TS3021IYLT are functionally equivalent to the LMV7239M7 with identical electrical specifications but housed in SOT-23-5 (SC-74A) package. These parts require PCB layout modification to accommodate the different pin configuration. TS3021IYLT includes AEC-Q100 automotive qualification. Both offer extended operating temperature range (-40°C ~ 125°C) and are ROHS3 compliant.

Lower-Power Alternative

MAX40009ANT+T (Analog Devices Inc./Maxim Integrated) provides significantly reduced quiescent current (17µA vs. 95µA) and lower input bias current (0.14µA), making it suitable for battery-powered or ultra-low-power applications. The 6-WLP package requires custom PCB design. Extended operating temperature range (-40°C ~ 125°C) is supported. Propagation delay is substantially higher (850ns typical), limiting use in timing-critical circuits.

Extended Supply Voltage Alternative

MIC7211YM5-TR (Microchip Technology) supports extended supply voltage range (2.2V ~ 10V) and offers the lowest quiescent current among SOT-23-5 alternatives (25µA). Propagation delay (5µs) is significantly higher, unsuitable for high-speed applications. Operating temperature range matches the LMV7239M7 (-40°C ~ 85°C).

Rail-to-Rail Output Alternative

TS3011ICT (STMicroelectronics) provides rail-to-rail push-pull output with 2mV hysteresis in SC-70-5 package. Quiescent current is elevated (1.1mA), and several electrical parameters are not specified. This part is suitable only when rail-to-rail output swing is a critical design requirement.

Frequently Asked Questions (FAQ)

Q: Can LMV7239M7/NOPB and LMV7239M7X/NOPB be used interchangeably with the LMV7239M7?

A: Yes. Both parts are parametric equivalents with identical electrical specifications and SC-70-5 package. The primary difference is packaging configuration (Cut Tape vs. Tape & Reel) and REACH compliance status. No design modifications are required.

Q: What is the key difference between SC-70-5 and SOT-23-5 package alternatives?

A: SC-70-5 and SOT-23-5 are different physical packages with different pin layouts and footprints. Substituting between these packages requires PCB redesign. TS3021ILT and TS3021IYLT use SOT-23-5 packaging and are not pin-compatible with the LMV7239M7 SC-70-5 footprint.

Q: Which substitute part offers the best low-power performance?

A: MAX40009ANT+T provides the lowest quiescent current (17µA) and input bias current (0.14µA). However, its 850ns propagation delay is significantly higher than the LMV7239M7 (62ns), making it unsuitable for timing-critical applications. MIC7211YM5-TR offers moderate power reduction (25µA quiescent) with SOT-23-5 packaging.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity rating, matching the LMV7239M7 environmental compliance profile.

Q: What is the operating temperature range limitation for direct substitution?

A: The LMV7239M7 operates from -40°C to 85°C. Several alternatives (MCP6561T-E/LT, TS3021ICT, TS3021ILT, TS3021IYLT, MAX40009ANT+T) extend this range to 125°C. If the application requires operation only within -40°C to 85°C, all listed alternatives are suitable. Extended temperature capability does not restrict use in standard-temperature applications.

Q: Can TS3011ICT be used as a direct replacement?

A: TS3011ICT is functionally compatible but not a direct replacement. It features rail-to-rail output and 2mV hysteresis, which the LMV7239M7 does not specify. Quiescent current is significantly higher (1.1mA vs. 95µA). Use TS3011ICT only when rail-to-rail output swing is a specific design requirement.

Q: Which substitute offers the fastest propagation delay?

A: LMV7239M7/NOPB and LMV7239M7X/NOPB maintain the original 62ns propagation delay. MCP6561T-E/LT provides 80ns, and TS3021 variants provide 105ns. MAX40009ANT+T (850ns) and MIC7211YM5-TR (5µs) are unsuitable for high-speed applications.

Q: Is automotive qualification available for substitute parts?

A: TS3021IYLT carries AEC-Q100 automotive qualification. This part is identical to TS3021ILT and TS3021ICT in electrical specifications but is specifically qualified for automotive applications. Use TS3021IYLT for automotive designs requiring formal qualification documentation.
