LMC6035IBP Equivalent & Substitute Parts

Part Overview

The LMC6035IBP is a CMOS operational amplifier manufactured by Texas Instruments, featuring two differential, rail-to-rail output circuits in an 8-DSBGA surface mount package. This device is classified as obsolete, indicating discontinued production and limited availability in the market. The LMC6035IBP was designed for low-power, precision analog signal conditioning applications requiring dual-channel amplification with rail-to-rail output capability.

Due to its obsolete status, sourcing original inventory becomes increasingly difficult. Substitute parts must maintain electrical equivalence across all critical performance parameters while offering improved availability or compliance status. The primary substitute identified is the LMC6035ITL/NOPB, which shares the same functional architecture and electrical specifications while offering superior market availability and enhanced compliance certifications.

Substitute Part Grouping Explanation

Substitution of the LMC6035IBP is determined by strict equivalence across electrical performance parameters and mechanical compatibility. The following criteria establish valid substitution:

Electrical Equivalence Requirements:

• Amplifier Type: CMOS (identical architecture)
• Number of Circuits: 2 (dual-channel configuration)
• Output Type: Differential, Rail-to-Rail (identical output stage)
• Slew Rate: 1.5 V/µs (identical dynamic response)
• Gain Bandwidth Product: 1.4 MHz (identical frequency response)
• Current - Input Bias: 0.02 pA (identical input characteristics)
• Voltage - Input Offset: 500 µV (identical DC precision)
• Current - Supply: 650 µA per channel (identical power consumption)
• Current - Output / Channel: 8 mA (identical output drive capability)
• Voltage - Supply Span: 2 V to 15.5 V (identical supply range)
• Operating Temperature Range: -40°C to 85°C (identical thermal specification)

Mechanical Compatibility Requirements:

• Mounting Type: Surface Mount (identical assembly method)
• Package / Case: 8-DSBGA or equivalent BGA footprint (identical PCB layout)
• Moisture Sensitivity Level: 1 (Unlimited) (identical handling requirements)

The LMC6035ITL/NOPB satisfies all electrical and mechanical equivalence criteria, making it a direct functional substitute for the LMC6035IBP.

Engineering Selection Recommendations

Primary Substitute: LMC6035ITL/NOPB

The LMC6035ITL/NOPB is the manufacturer-recommended substitute for the obsolete LMC6035IBP. This substitution is based on the following engineering factors:

Electrical Compatibility: All electrical parameters are identical between the two parts. The LMC6035ITL/NOPB maintains the same CMOS architecture, dual-channel configuration, differential rail-to-rail output stage, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, and supply voltage range. The operating temperature specification is also identical.

Mechanical Compatibility: Both parts utilize surface mount technology with 8-pin BGA packaging. The LMC6035ITL/NOPB uses an 8-WFBGA or 8-DSBGA package, which is mechanically compatible with the LMC6035IBP's 8-VFBGA footprint. Moisture sensitivity level remains unchanged at MSL 1 (Unlimited).

Compliance and Availability: The LMC6035ITL/NOPB holds Last Time Buy status, indicating extended availability compared to the obsolete LMC6035IBP. The substitute achieves RoHS3 compliance, whereas the original part is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

Packaging Consideration: The LMC6035ITL/NOPB is supplied in Cut Tape (CT) and Digi-Reel® format, differing from the original Tape & Reel (TR) packaging. This difference does not affect electrical or mechanical performance and reflects standard industry packaging variations.

Frequently Asked Questions (FAQ)

Q: Can the LMC6035ITL/NOPB be used as a direct replacement for the LMC6035IBP in existing designs?

A: Yes. The LMC6035ITL/NOPB is electrically and mechanically equivalent to the LMC6035IBP across all specified parameters. No circuit modifications are required. The 8-DSBGA package footprint is compatible with the original 8-VFBGA layout.

Q: What is the difference between the packaging formats (Tape & Reel vs. Cut Tape & Digi-Reel)?

A: Packaging format refers to the delivery method for surface mount components. Tape & Reel (TR) supplies components on continuous carrier tape in reel format, typically for high-volume automated assembly. Cut Tape (CT) and Digi-Reel® provide the same components in smaller quantities or alternative reel configurations. The electrical and mechanical properties of the component itself remain unchanged.

Q: Why is the LMC6035IBP classified as obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued production of this part number. The LMC6035ITL/NOPB represents the current production equivalent, offering the same functionality with improved compliance and extended availability.

Q: Does the RoHS3 compliance of the LMC6035ITL/NOPB affect its electrical performance?

A: No. RoHS3 compliance is a regulatory and environmental certification that restricts hazardous substances in manufacturing. It does not alter the electrical specifications, performance characteristics, or functional behavior of the component.

Q: Are there any thermal or reliability differences between these two parts?

A: No. Both parts share identical operating temperature ranges (-40°C to 85°C) and moisture sensitivity levels (MSL 1, Unlimited). The electrical performance, power consumption, and thermal characteristics are equivalent.

Q: What inventory status should I expect for each part?

A: The LMC6035IBP has 2400 pieces in stock but is obsolete, meaning inventory will eventually deplete. The LMC6035ITL/NOPB has 6863 pieces in stock and holds Last Time Buy status, providing extended availability for new designs and production runs.

Q: Can I mix LMC6035IBP and LMC6035ITL/NOPB parts in the same production batch?

A: Yes. Since both parts are electrically and mechanically equivalent, they can be used interchangeably within the same circuit board design. However, for consistency and traceability, it is standard practice to standardize on a single part number per production run.
