LMC6035IBPX Equivalent & Substitute Parts

Part Overview

The LMC6035IBPX is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, featuring differential, rail-to-rail output configuration in an 8-DSBGA surface mount package. This device is classified as Obsolete, indicating discontinued production and limited availability in the market. The identification of equivalent substitute parts is necessary to maintain design continuity and ensure component procurement for new production runs or design revisions where the original part number is no longer available through standard distribution channels.

Substitute Part Grouping Explanation

Substitution of the LMC6035IBPX is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: CMOS
• Number of Circuits: 2
• Output Type: Differential, Rail-to-Rail
• Slew Rate: 1.5 V/µs
• Gain Bandwidth Product: 1.4 MHz
• Current - Input Bias: 0.02 pA
• Voltage - Input Offset: 500 µV
• Current - Supply: 650 µA (x2 Channels)
• Current - Output / Channel: 8 mA
• Voltage - Supply Span: 2 V to 15.5 V
• Operating Temperature Range: -40°C to 85°C

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package Configuration: 8-DSBGA (Ball Grid Array)
• Base Product Number: LMC6035

The substitute part LMC6035ITL/NOPB maintains complete electrical and mechanical compatibility with the original LMC6035IBPX, differing only in packaging format (Cut Tape & Digi-Reel) and product status classification.

Engineering Selection Recommendations

LMC6035ITL/NOPB Selection Basis:

The LMC6035ITL/NOPB is the direct functional equivalent of the LMC6035IBPX. All electrical parameters, mechanical specifications, and operating characteristics are identical. The substitute part differs in two non-functional aspects:

1. Product Status: The LMC6035ITL/NOPB carries a "Last Time Buy" classification, indicating controlled availability with a defined end-of-life timeline. This status provides superior supply chain predictability compared to the Obsolete status of the original part.

2. RoHS Compliance: The LMC6035ITL/NOPB is ROHS3 Compliant, whereas the LMC6035IBPX is RoHS non-compliant. This distinction is significant for applications subject to regulatory requirements mandating lead-free component usage.

Selection Criteria:

• For applications requiring RoHS compliance or operating in regulated markets, the LMC6035ITL/NOPB is the appropriate selection.
• For legacy systems or applications without RoHS requirements, either part is electrically and mechanically interchangeable.
• The LMC6035ITL/NOPB offers superior long-term availability assurance through its Last Time Buy status.

Frequently Asked Questions (FAQ)

Q: Are the LMC6035IBPX and LMC6035ITL/NOPB pin-compatible?

A: Yes. Both devices use the 8-DSBGA package configuration with identical pin assignments, electrical characteristics, and functional behavior. Direct substitution is possible without circuit modification.

Q: What is the difference between the package designations 8-VFBGA and 8-WFBGA?

A: The LMC6035IBPX specifies 8-VFBGA as its package case designation, while the LMC6035ITL/NOPB specifies 8-WFBGA. Both reference the same 8-DSBGA supplier device package with identical physical dimensions (1.56x1.56 mm). The variation in case designation reflects different internal classification systems but does not indicate physical or functional differences.

Q: Why is the LMC6035IBPX classified as Obsolete?

A: Obsolete classification indicates that Texas Instruments has discontinued production of this specific part number. The LMC6035ITL/NOPB represents the current production equivalent with Last Time Buy status, providing a defined procurement window before complete discontinuation.

Q: Can I use the LMC6035ITL/NOPB in a design originally specified for the LMC6035IBPX?

A: Yes. The LMC6035ITL/NOPB is electrically and mechanically equivalent. No design changes are required. The only consideration is RoHS compliance status; if your application or market requires RoHS compliance, the LMC6035ITL/NOPB is the appropriate choice.

Q: What does "Last Time Buy" status mean for the LMC6035ITL/NOPB?

A: Last Time Buy indicates that Texas Instruments will continue production for a limited period before discontinuation. This status provides a defined window for procurement planning. After the Last Time Buy date, the part will transition to Obsolete status.

Q: Are there any differences in supply chain availability between these two parts?

A: The LMC6035IBPX has 16,240 pieces in stock, while the LMC6035ITL/NOPB has 6,863 pieces in stock. Both are available as new original inventory. The LMC6035ITL/NOPB's Last Time Buy status provides superior long-term availability predictability compared to the Obsolete status of the LMC6035IBPX.

Q: What is the significance of the "/NOPB" suffix in the LMC6035ITL/NOPB part number?

A: The "/NOPB" suffix indicates "No Plumbum" (lead-free) packaging, confirming RoHS3 compliance and the absence of lead in the component construction.
