Part Overview

The LMC7225IM5 is a general-purpose comparator IC manufactured by Texas Instruments, featuring open-drain output in SOT-23-5 surface mount packaging. This part is classified as obsolete, making equivalent and substitute parts necessary for new designs and production continuity. The LMC7225IM5 operates across a wide supply voltage range (2V to 8V single supply, ±1V to ±4V dual supply) and delivers 30mA typical output current with minimal quiescent current consumption of 1µA maximum.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LMC7225IM5 is determined by the following critical parameters:

Primary Substitution Criteria:

• Output Type: Open-Drain configuration
• Number of Elements: Single comparator
• Supply Voltage Compatibility: Minimum overlap with 2V ~ 8V range
• Package Compatibility: Surface mount with compatible pinout
• Operating Temperature Range: Minimum -40°C to 85°C coverage
• RoHS3 Compliance and MSL Level 1 rating

Acceptable Variation Parameters:

• Input Offset Voltage: Up to 11mV @ rated voltage
• Quiescent Current: Up to 220µA maximum
• Propagation Delay: Up to 1.8µs typical
• Output Current: 6mA to 93mA range
• CMRR/PSRR: Specifications may vary or be unspecified

Substitute parts are grouped into two categories: direct Texas Instruments variants (LMC7225IM5/NOPB, LMC7225IM5X/NOPB) and cross-manufacturer alternatives meeting the core electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Highest Compatibility): LMC7225IM5/NOPB and LMC7225IM5X/NOPB are direct Texas Instruments variants with identical electrical specifications to the obsolete LMC7225IM5. Both parts are active products with ROHS3 compliance and MSL Level 1 rating. LMC7225IM5X/NOPB is supplied in Tape & Reel packaging with higher inventory availability (13,200 units) compared to LMC7225IM5/NOPB (2,100 units in Cut Tape format).

Cross-Manufacturer Alternatives: TC75S59F,LF (Toshiba) provides the closest electrical match among cross-manufacturer options, with 7mV input offset voltage and 25mA output current within acceptable tolerance of the original specification. Operating temperature range matches the LMC7225IM5 (-40°C to 85°C), and supply voltage range (1.8V ~ 7V) encompasses the original specification. ROHS3 compliance and MSL Level 1 rating are confirmed.

LMV331ICT (STMicroelectronics) and LMV331SQ3T2G (onsemi) offer superior propagation delay performance (550ns and 1.5µs respectively versus 29µs) with higher output current capability (93mA and 84mA). These parts operate within the 2.7V ~ 5V range, which overlaps the original 2V ~ 8V specification. Both maintain ROHS3 compliance and MSL Level 1 rating.

BU7230G-TR (Rohm Semiconductor) features the fastest propagation delay (1.8µs typical) and lowest input bias current (1pA typical). Supply voltage range (1.8V ~ 5.5V) partially overlaps the original specification. ROHS3 compliance and MSL Level 1 rating are confirmed.

ADCMP354YKSZ-REEL7 (Analog Devices Inc.) and MAX40003ANS02+ (Analog Devices Inc./Maxim Integrated) include integrated voltage reference functionality, extending operating temperature to -40°C to 125°C. These parts are suitable for applications requiring wider temperature operation. Both maintain ROHS3 compliance and MSL Level 1 rating.

Selection Basis: All substitute parts listed meet the mandatory criteria of open-drain output, single comparator element, surface mount configuration, ROHS3 compliance, and MSL Level 1 rating. Selection should prioritize product status (active versus obsolete), supply voltage range compatibility with the target application, and package compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can LMC7225IM5/NOPB be used as a direct replacement for the obsolete LMC7225IM5?

A: Yes. LMC7225IM5/NOPB is electrically and mechanically identical to LMC7225IM5, with the primary difference being active product status and packaging format (Cut Tape with Digi-Reel option). Both parts share identical electrical specifications including 6mV input offset voltage, 30mA output current, and 29µs propagation delay.

Q: What is the difference between LMC7225IM5/NOPB and LMC7225IM5X/NOPB?

A: Both parts are electrically identical with matching specifications. The primary difference is packaging: LMC7225IM5/NOPB is supplied in Cut Tape format, while LMC7225IM5X/NOPB is supplied in Tape & Reel format. LMC7225IM5X/NOPB has significantly higher inventory availability (13,200 units versus 2,100 units).

Q: Are cross-manufacturer comparators compatible with the LMC7225IM5 in all applications?

A: Cross-manufacturer substitutes meet the core electrical and mechanical requirements (open-drain output, single element, surface mount, operating temperature -40°C to 85°C, ROHS3 compliance). However, application-specific factors such as propagation delay, input offset voltage tolerance, output current capability, and supply voltage range must be evaluated. TC75S59F,LF provides the closest electrical match among cross-manufacturer options.

Q: What package compatibility issues should be considered?

A: The LMC7225IM5 uses SOT-23-5 packaging. Direct replacements (LMC7225IM5/NOPB and LMC7225IM5X/NOPB) maintain identical packaging. Cross-manufacturer alternatives use different packages: TC75S59F,LF uses SMV, LMV331ICT uses SC-70-5, LMV331SQ3T2G uses SC-88A, ADCMP354YKSZ-REEL7 uses SC-70-4, BU7230G-TR uses 5-SSOP, and MAX40003ANS02+ uses 4-WLP. PCB redesign may be required for non-SOT-23-5 packages.

Q: Which substitute offers the fastest response time?

A: TC75S59F,LF provides 200ns propagation delay, followed by BU7230G-TR at 1.8µs typical. The original LMC7225IM5 specifies 29µs maximum propagation delay. LMV331ICT and LMV331SQ3T2G offer 550ns and 1.5µs respectively. ADCMP354YKSZ-REEL7 and MAX40003ANS02+ do not specify propagation delay in the provided data.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original LMC7225IM5 environmental specifications.

Q: What is the supply voltage compatibility range for cross-manufacturer substitutes?

A: TC75S59F,LF operates at 1.8V ~ 7V (±0.9V ~ 4.6V dual), fully encompassing the original 2V ~ 8V range. LMV331ICT and LMV331SQ3T2G operate at 2.7V ~ 5V, which overlaps but does not fully cover the original range. BU7230G-TR operates at 1.8V ~ 5.5V (±0.9V ~ 2.75V dual). ADCMP354YKSZ-REEL7 operates at 2.25V ~ 5.5V. MAX40003ANS02+ operates at 1.7V ~ 5.5V. Applications requiring operation below 2.7V should use TC75S59F,LF or BU7230G-TR.
