LTC2050CS5#TR Equivalent & Substitute Parts

Part Overview

The LTC2050CS5#TR is an active chopper (zero-drift) amplifier manufactured by Analog Devices Inc., designed for precision analog signal conditioning applications. This single-circuit, rail-to-rail operational amplifier is housed in a TSOT-23-5 surface mount package and operates across a 2.7 V to 6 V supply range. The device is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when inventory constraints, packaging format requirements, or specific application parameters necessitate alternative component selection while maintaining functional equivalence.

Substitute Part Grouping Explanation

Substitute parts for the LTC2050CS5#TR are identified based on strict electrical and mechanical parameter alignment within the linear amplifier category. The substitution logic is structured into two groupings:

Direct Equivalent (Packaging Variant): The LTC2050CS5#TRPBF maintains identical electrical specifications, package type (TSOT-23-5), and manufacturing base (Analog Devices Inc. LTC2050 series). This substitute differs only in packaging format (Tape & Reel with lead-free designation) and is suitable for applications where packaging configuration is the primary selection driver.

Similar Functional Equivalent (Parameter Tolerance): The NCS325SN2T1G (onsemi) operates as a zero-drift amplifier with rail-to-rail output in the same TSOT-23-5 package footprint. This substitute is classified as similar rather than direct due to measurable differences in slew rate (0.16 V/µs vs. 2 V/µs), gain bandwidth product (350 kHz vs. 3 MHz), input offset voltage (14 µV vs. 0.5 µV), supply current (21 µA vs. 800 µA), and operating temperature range (-40°C to 125°C vs. 0°C to 70°C). Selection of this substitute requires confirmation that application bandwidth and offset voltage specifications accommodate the stated parameter deviations.

Parameter Comparison

Engineering Selection Recommendations

LTC2050CS5#TRPBF Selection: This direct equivalent substitute is appropriate for applications where the primary constraint is packaging format availability. Both devices share identical electrical performance specifications, base product lineage (LTC2050 series), and regulatory compliance status (RoHS3, REACH Unaffected). The TRPBF variant is suitable for high-volume manufacturing environments utilizing tape-and-reel delivery formats with lead-free solder compatibility requirements.

NCS325SN2T1G Selection: This similar functional equivalent is appropriate only for applications where the specified parameter deviations are acceptable within system design margins. The NCS325SN2T1G exhibits lower slew rate (0.16 V/µs), reduced gain bandwidth product (350 kHz), higher input offset voltage (14 µV), and significantly lower supply current (21 µA). The extended operating temperature range (-40°C to 125°C) provides broader environmental coverage. Selection of this substitute requires explicit confirmation that application signal bandwidth, offset voltage tolerance, and power consumption specifications are compatible with the stated electrical differences. All three devices maintain equivalent regulatory compliance (RoHS3, REACH Unaffected, MSL 1).

Frequently Asked Questions (FAQ)

Q: Can LTC2050CS5#TRPBF be used as a direct replacement for LTC2050CS5#TR?

A: Yes. The LTC2050CS5#TRPBF is a direct electrical equivalent with identical specifications for slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and operating temperature range. The difference is packaging format: TRPBF is supplied in tape-and-reel format with lead-free designation, while TR is the standard reel format. Both are manufactured by Analog Devices Inc. and share the same base product number (LTC2050).

Q: What are the key differences between LTC2050CS5#TR and NCS325SN2T1G?

A: The primary differences are slew rate (2 V/µs vs. 0.16 V/µs), gain bandwidth product (3 MHz vs. 350 kHz), input offset voltage (0.5 µV vs. 14 µV), supply current (800 µA vs. 21 µA), and operating temperature range (0°C to 70°C vs. -40°C to 125°C). Both devices are zero-drift amplifiers with rail-to-rail output in TSOT-23-5 packages. The NCS325SN2T1G is manufactured by onsemi.

Q: Is the NCS325SN2T1G suitable for high-speed signal conditioning applications?

A: No. The NCS325SN2T1G has a gain bandwidth product of 350 kHz and slew rate of 0.16 V/µs, which are significantly lower than the LTC2050CS5#TR specifications (3 MHz and 2 V/µs respectively). The NCS325SN2T1G is optimized for low-power, low-bandwidth applications. Applications requiring the higher bandwidth and slew rate of the LTC2050CS5#TR should not use the NCS325SN2T1G as a substitute.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the SOT-23-5 Thin (TSOT-23-5) package and are surface mount devices. PCB footprints are mechanically compatible. However, electrical performance differences between the LTC2050 series and NCS325SN2T1G require circuit design verification before substitution.

Q: What is the difference between the TR and TRPBF packaging designations?

A: TR indicates standard tape-and-reel packaging. TRPBF indicates tape-and-reel packaging with lead-free (PbF) solder compatibility. Both are surface mount delivery formats. The TRPBF variant is typically specified for manufacturing environments with lead-free assembly requirements.

Q: Do all three parts meet RoHS3 compliance?

A: Yes. LTC2050CS5#TR, LTC2050CS5#TRPBF, and NCS325SN2T1G are all RoHS3 compliant with REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can the NCS325SN2T1G operate at the same supply voltage as the LTC2050CS5#TR?

A: Partial compatibility exists. The LTC2050CS5#TR operates from 2.7 V to 6 V, while the NCS325SN2T1G operates from 1.8 V to 5.5 V. The NCS325SN2T1G supports lower minimum supply voltage (1.8 V) but has a lower maximum supply voltage (5.5 V vs. 6 V). Applications using 5.5 V to 6 V supply are not compatible with the NCS325SN2T1G.
