TLC2252CPW Equivalent & Substitute Parts

Part Overview

The TLC2252CPW is a general-purpose operational amplifier featuring two circuits in a rail-to-rail output configuration, manufactured by Texas Instruments using LinCMOS™ technology. This device is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and production continuity. The TLC2252CPW operates across a 4.4V to 16V supply range with low input bias current and is packaged in an 8-TSSOP surface-mount configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC2252CPW is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Dual-circuit configuration (2 circuits required)
• Rail-to-rail output capability
• Slew rate of 0.12 V/µs or greater
• Gain bandwidth product of 200 kHz or greater
• Input bias current of 1 pA or lower
• Supply voltage range encompassing 4.4V minimum to 16V maximum
• Output current capability of 50 mA per channel or greater

Mechanical Compatibility Criteria:

• 8-pin surface-mount package (8-TSSOP or equivalent footprint)
• RoHS3 compliance
• MSL rating of 1 (Unlimited)

Identified Substitutes:

1. TLC2252CPWR (Texas Instruments) — Direct manufacturer equivalent with identical electrical specifications, differentiated only by packaging format (Tape & Reel vs. tube). Product status is Active.

2. TSX632IYST (STMicroelectronics) — Functional substitute meeting all electrical and mechanical criteria with extended operating temperature range (-40°C to 125°C) and automotive qualification (AEC-Q100). Minor parameter variations exist within acceptable substitution tolerances.

Parameter Comparison

Engineering Selection Recommendations

TLC2252CPWR Selection: The TLC2252CPWR is the primary recommended substitute for the obsolete TLC2252CPW. This part maintains identical electrical specifications and operating parameters while offering Active product status from Texas Instruments. The only distinction is packaging format: TLC2252CPWR is supplied in Tape & Reel configuration versus the original tube packaging. Both parts are ROHS3 compliant with MSL rating of 1. This substitute is appropriate for direct replacement in existing designs without circuit modification.

TSX632IYST Selection: The TSX632IYST from STMicroelectronics serves as a functional substitute where extended operating temperature range or automotive-grade qualification is required. This part meets all electrical and mechanical substitution criteria with the following considerations: operating temperature extends to -40°C to 125°C (versus 0°C to 70°C for TLC2252CPW), input offset voltage is 1.6 mV (versus 200 µV), supply current is reduced to 45 µA (versus 80 µA), and output current per channel is increased to 92 mA (versus 50 mA). The TSX632IYST carries AEC-Q100 automotive qualification and is suitable for applications requiring extended temperature performance or automotive-grade components. Package footprint compatibility exists between 8-TSSOP and 8-MiniSO configurations.

Frequently Asked Questions (FAQ)

Q: Can TLC2252CPWR be used as a direct replacement for TLC2252CPW?

A: Yes. The TLC2252CPWR is electrically and mechanically identical to the TLC2252CPW. The only difference is packaging format (Tape & Reel versus tube). Both parts feature identical electrical specifications, pin configuration, and performance characteristics. The TLC2252CPWR is the manufacturer-recommended substitute with Active product status.

Q: What are the key differences between TLC2252CPWR and TSX632IYST?

A: Both parts are dual-circuit, rail-to-rail operational amplifiers in 8-pin surface-mount packages with identical slew rates (0.12 V/µs) and input bias current (1 pA). The TSX632IYST differs in: operating temperature range (-40°C to 125°C versus 0°C to 70°C), input offset voltage (1.6 mV versus 200 µV), supply current (45 µA versus 80 µA), output current per channel (92 mA versus 50 mA), and includes automotive qualification (AEC-Q100). The TSX632IYST is suitable for extended-temperature or automotive applications.

Q: Are package footprints compatible between TLC2252CPW and TSX632IYST?

A: Both parts use 8-pin surface-mount packages with compatible footprints. TLC2252CPW uses 8-TSSOP (0.173", 4.40mm width) and TSX632IYST uses 8-MiniSO (0.118", 3.00mm width). While pin pitch differs, both are recognized as compatible 8-pin TSSOP-family packages for substitution purposes. PCB layout verification is required for specific applications.

Q: Does TSX632IYST meet the same compliance standards as TLC2252CPW?

A: Yes. Both TLC2252CPW and TSX632IYST are ROHS3 compliant with MSL rating of 1 (Unlimited). Both carry REACH Unaffected status and EAR99 ECCN classification. The TSX632IYST additionally carries AEC-Q100 automotive qualification, which does not conflict with industrial applications.

Q: What supply voltage range must be maintained for substitution?

A: The TLC2252CPW operates across 4.4V to 16V. The TLC2252CPWR maintains this identical range. The TSX632IYST operates across 3.3V to 16V, providing a wider minimum supply voltage capability. All three parts are compatible with supply voltages within the 4.4V to 16V range.

Q: Can these parts be used interchangeably in existing PCB designs?

A: TLC2252CPWR can be used interchangeably with TLC2252CPW without design modification. TSX632IYST requires PCB layout verification due to package footprint differences (8-TSSOP versus 8-MiniSO), though pin configuration remains compatible. Electrical performance differences in input offset voltage and output current should be evaluated for specific circuit applications.
