LMC6772AIMM Equivalent & Substitute Parts

Part Overview

The LMC6772AIMM is a dual-channel general-purpose comparator manufactured by Texas Instruments, housed in an 8-VSSOP surface-mount package. This device features open-drain outputs and operates across a wide supply voltage range of 2.7V to 15V (single supply) or ±1.35V to ±7.5V (dual supply). The LMC6772AIMM is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity. Substitute parts maintain identical electrical and mechanical specifications while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LMC6772AIMM are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

Electrical Performance: Voltage supply range (2.7V ~ 15V single, ±1.35V ~ 7.5V dual), input offset voltage (5mV @ 5V), input bias current (0.04pA @ 5V), output current capability (30mA typical), quiescent current (20µA maximum), CMRR/PSRR performance (75dB/80dB), and propagation delay (10µs maximum).

Package Compatibility: 8-VSSOP surface-mount package with 8-TSSOP/8-MSOP footprint equivalence (0.118", 3.00mm width).

Functional Equivalence: Dual-channel general-purpose comparator with open-drain output configuration.

Compliance & Certification: ROHS3 compliance, MSL Level 1, and identical ECCN/HTSUS classifications.

The substitute parts LMC6772AIMM/NOPB and LMC6772AIMMX/NOPB maintain 100% parametric compatibility with the main part number while offering active product status and higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both LMC6772AIMM/NOPB and LMC6772AIMMX/NOPB are direct parametric equivalents to the obsolete LMC6772AIMM. Selection between substitute parts should be based on the following criteria:

Product Status: The main part number LMC6772AIMM is classified as obsolete. Both substitute parts maintain active product status with Texas Instruments, ensuring long-term availability and continued manufacturing support.

Compliance & Certifications: All three part numbers maintain identical ROHS3 compliance, MSL Level 1 rating, and equivalent ECCN/HTSUS classifications, confirming regulatory and environmental compliance across all variants.

Packaging & Availability: LMC6772AIMM/NOPB is supplied in Tape & Reel (TR) packaging with 3439 units in stock. LMC6772AIMMX/NOPB is also supplied in Tape & Reel (TR) packaging with significantly higher inventory of 45100 units. The "X" suffix in LMC6772AIMMX/NOPB indicates extended temperature or manufacturing process qualification, with no impact on electrical performance or package compatibility.

For new designs and production continuity, LMC6772AIMMX/NOPB is recommended due to superior inventory availability and active product status. LMC6772AIMM/NOPB serves as an alternative substitute with equivalent electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can LMC6772AIMM/NOPB and LMC6772AIMMX/NOPB be used interchangeably with LMC6772AIMM?

A: Yes. Both substitute parts are parametric equivalents with identical electrical specifications, package dimensions, and pin configurations. They are direct drop-in replacements for the obsolete LMC6772AIMM in all applications.

Q: What is the difference between LMC6772AIMM/NOPB and LMC6772AIMMX/NOPB?

A: Both parts are electrically and mechanically identical. The "X" suffix indicates a manufacturing process or qualification variant. No functional differences exist between the two part numbers. Selection should be based on availability and lead time requirements.

Q: Are the substitute parts compatible with existing PCB layouts designed for LMC6772AIMM?

A: Yes. All three part numbers use the identical 8-VSSOP package with 8-TSSOP/8-MSOP footprint equivalence (0.118", 3.00mm width). Pin configuration and spacing are identical, ensuring 100% PCB layout compatibility.

Q: What is the significance of the "/NOPB" suffix?

A: The "/NOPB" suffix indicates "No Plumbum" (lead-free) packaging, confirming ROHS3 compliance. This is standard for current production parts and does not affect electrical performance or compatibility.

Q: Why is the main part number LMC6772AIMM classified as obsolete?

A: Obsolescence typically results from manufacturer product line consolidation or transition to newer process technologies. The substitute parts LMC6772AIMM/NOPB and LMC6772AIMMX/NOPB represent the active production equivalents and are recommended for all new designs.

Q: Are there any thermal or performance differences between the substitute parts and the main part?

A: No. All three part numbers maintain identical operating temperature range (-40°C ~ 85°C), quiescent current (20µA maximum), and all other electrical specifications. Thermal performance is equivalent across all variants.

Q: What packaging formats are available for the substitute parts?

A: Both LMC6772AIMM/NOPB and LMC6772AIMMX/NOPB are supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The original LMC6772AIMM was available in Cut Tape (CT) & Digi-Reel® format.
