TLC2252ID Equivalent & Substitute Parts

Part Overview

The TLC2252ID is a general-purpose operational amplifier featuring dual circuits in a rail-to-rail configuration, manufactured by Texas Instruments in the LinCMOS™ series. This device is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design requirements and production continuity. The TLC2252ID operates across a wide supply voltage range and is suitable for applications requiring low input bias current and moderate bandwidth performance in surface-mount 8-SOIC packaging.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC2252ID is determined by the following critical parameters:

Primary Substitution Criteria:

• Package type: 8-SOIC form factor (0.154", 3.90mm Width)
• Number of circuits: Dual-channel configuration
• Output configuration: Rail-to-rail capability
• Mounting technology: Surface mount
• Supply voltage compatibility: Minimum 4.4 V to maximum 16 V range
• Compliance standards: ROHS3 compliance and REACH unaffected status

Substitute Parts Identified:

1. TLC2252IDR — Direct manufacturer equivalent with identical electrical specifications and active product status
2. LMC6042AIM/NOPB — Functional alternative with modified electrical characteristics and different amplifier topology

Parameter Comparison

Engineering Selection Recommendations

TLC2252IDR is the primary recommended substitute for the obsolete TLC2252ID. This part maintains identical electrical specifications, including slew rate, gain bandwidth product, input bias current, and output current ratings. The TLC2252IDR carries active product status from Texas Instruments, ensuring long-term availability and supply chain continuity. Both parts share identical package specifications, operating temperature range, and compliance certifications (ROHS3, REACH unaffected). Direct pin-to-pin compatibility and functional equivalence make TLC2252IDR suitable for direct replacement without circuit modification.

LMC6042AIM/NOPB serves as a functional alternative when specific design requirements align with its electrical characteristics. This substitute exhibits lower supply current consumption (26 µA versus 80 µA), reduced input bias current (0.002 pA versus 1 pA), and lower slew rate (0.02 V/µs versus 0.12 V/µs). The LMC6042AIM/NOPB operates at a reduced maximum temperature (85°C versus 125°C) and carries Last Time Buy status. Selection of this alternative requires verification that reduced bandwidth (100 kHz versus 210 kHz) and slew rate performance align with application requirements. The identical 8-SOIC package and rail-to-rail output configuration maintain mechanical and electrical interface compatibility.

Frequently Asked Questions (FAQ)

Q: Can TLC2252IDR be used as a direct replacement for TLC2252ID?

A: Yes. The TLC2252IDR is electrically and mechanically identical to the TLC2252ID. All electrical parameters, package specifications, and pin configurations match exactly. The primary difference is product status: TLC2252IDR is active, while TLC2252ID is obsolete. Direct substitution requires no circuit modifications.

Q: What are the key differences between TLC2252IDR and LMC6042AIM/NOPB?

A: The primary differences are amplifier topology (General Purpose versus CMOS), slew rate (0.12 V/µs versus 0.02 V/µs), gain bandwidth product (210 kHz versus 100 kHz), supply current (80 µA versus 26 µA), and maximum operating temperature (125°C versus 85°C). Both maintain 8-SOIC packaging and rail-to-rail output capability. Selection depends on whether the application requires the higher bandwidth and temperature range of the TLC2252IDR or the lower power consumption of the LMC6042AIM/NOPB.

Q: Are all substitute parts in the same package?

A: Yes. Both TLC2252IDR and LMC6042AIM/NOPB use the 8-SOIC (0.154", 3.90mm Width) surface-mount package. Pin-to-pin compatibility is maintained across all three parts for this package type.

Q: What is the supply voltage compatibility range for these parts?

A: TLC2252ID and TLC2252IDR operate across 4.4 V to 16 V. LMC6042AIM/NOPB operates across 4.5 V to 15.5 V. Applications requiring the full 4.4 V minimum or 16 V maximum must use TLC2252IDR. The LMC6042AIM/NOPB is compatible with most standard supply ranges but has slightly narrower limits.

Q: Do all parts meet RoHS and REACH compliance requirements?

A: Yes. TLC2252ID, TLC2252IDR, and LMC6042AIM/NOPB are all ROHS3 compliant and REACH unaffected. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.

Q: What is the operating temperature range for each part?

A: TLC2252ID and TLC2252IDR operate from -40°C to 125°C. LMC6042AIM/NOPB operates from -40°C to 85°C (TJ). Applications requiring operation above 85°C must use TLC2252IDR.

Q: Why is LMC6042AIM/NOPB marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has announced end-of-life for this product. Existing inventory is available, but no future production is planned. For new designs or long-term production requirements, TLC2252IDR is the recommended choice due to its active product status.
