Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMC6772AIM/NOPB is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of comparator elements (2 channels required for direct replacement)
• Output type (open-drain configuration)
• Supply voltage range compatibility (minimum 2.7V to 15V single supply)
• Package type (8-SOIC surface mount)
• Input offset voltage specification (5mV or lower)
• Propagation delay performance (10µs or faster)

Substitution Categories:

Direct Manufacturer Equivalent (MFR Recommended): LMC6772AIMX/NOPB differs only in packaging format (Tape & Reel vs. Tube) while maintaining identical electrical specifications and active product status.

Parametric Equivalent: LMC7221AIM/NOPB is a single-channel variant from the same manufacturer family. While it contains only one comparator element instead of two, it maintains identical electrical performance characteristics, supply voltage range, and package dimensions. This part is suitable for applications requiring only one comparator channel.

Cross-Manufacturer Alternatives: BU7233F-E2, BU7233SF-E2, and BU7253F-E2 from Rohm Semiconductor are CMOS-type comparators with dual channels and open-drain outputs. These parts operate within a narrower supply voltage range (1.8V ~ 5.5V) and exhibit different quiescent current specifications, but maintain compatibility with the 8-SOIC package footprint and open-drain output configuration.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): LMC6772AIMX/NOPB is the primary recommendation. This part maintains all electrical specifications of the original LMC6772AIM/NOPB while offering active product status and availability in Tape & Reel packaging format, which is preferred for high-volume manufacturing operations.

For Single-Channel Applications: LMC7221AIM/NOPB provides an active alternative when only one comparator channel is required. This part maintains identical electrical performance and supply voltage range specifications as the main part, with marginally lower quiescent current consumption (14µA vs. 20µA maximum).

For Supply Voltage Range Constraints (1.8V ~ 5.5V): BU7233F-E2, BU7233SF-E2, and BU7253F-E2 from Rohm Semiconductor are suitable only for applications operating within the narrower 1.8V to 5.5V supply voltage range. These CMOS comparators offer faster propagation delay performance (750ns to 1.8µs typical) compared to the LMC6772AIM/NOPB (10µs maximum). BU7233SF-E2 extends the operating temperature range to 105°C and maintains the exact 8-SOIC (0.154", 3.90mm) package footprint. BU7253F-E2 offers the fastest propagation delay (750ns typical) but exhibits higher quiescent current consumption (65µA maximum).

Compliance and Certification: All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical ECCN and HTSUS classifications as the original part, ensuring regulatory and supply chain compatibility.

Frequently Asked Questions (FAQ)

Q: Can LMC6772AIMX/NOPB be used as a direct replacement for LMC6772AIM/NOPB? A: Yes. LMC6772AIMX/NOPB is electrically and functionally identical to LMC6772AIM/NOPB. The only difference is packaging format: LMC6772AIMX/NOPB is supplied in Tape & Reel format while LMC6772AIM/NOPB is supplied in Tube format. Both parts are pin-compatible and have identical electrical specifications.

Q: Why would I choose LMC7221AIM/NOPB over LMC6772AIM/NOPB? A: LMC7221AIM/NOPB contains a single comparator element instead of two. Select this part only if your application requires only one comparator channel. It offers identical electrical performance and supply voltage range specifications with slightly lower quiescent current consumption.

Q: Are the Rohm Semiconductor parts (BU7233F-E2, BU7233SF-E2, BU7253F-E2) direct replacements? A: No. These parts are cross-manufacturer alternatives suitable only for applications operating within the 1.8V to 5.5V supply voltage range. The LMC6772AIM/NOPB supports higher supply voltages (up to 15V single supply). The Rohm parts offer faster propagation delay but have different input offset voltage and quiescent current specifications. Verify supply voltage requirements before substitution.

Q: What is the difference between BU7233F-E2 and BU7233SF-E2? A: BU7233SF-E2 extends the operating temperature range to 105°C (compared to 85°C for BU7233F-E2) and maintains the exact 8-SOIC (0.154", 3.90mm) package footprint. BU7233F-E2 uses a slightly wider 8-SOIC package (0.173", 4.40mm). Both parts have identical electrical specifications.

Q: Why does BU7253F-E2 have higher quiescent current than other alternatives? A: BU7253F-E2 is specified with 65µA maximum quiescent current compared to 25µA for BU7233F-E2 and BU7233SF-E2. However, BU7253F-E2 offers significantly faster propagation delay (750ns typical vs. 1.8µs typical). Select BU7253F-E2 only if faster switching speed is required and higher quiescent current consumption is acceptable for your application.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All substitute parts listed maintain ROHS3 compliance, MSL Level 1 rating, and identical regulatory classifications as the original LMC6772AIM/NOPB.

Q: What packaging formats are available for these parts? A: LMC6772AIM/NOPB is supplied in Tube format. LMC6772AIMX/NOPB is supplied in Tape & Reel format. LMC7221AIM/NOPB is supplied in Tube format. Rohm parts are supplied in Tape & Reel or Cut Tape & Digi-Reel formats. Verify packaging requirements for your procurement and assembly processes.
