Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TC75W54FU,LF are identified based on functional equivalence within the following critical parameters:

Functional Equivalence Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 2
• Package Category: 8-pin TSSOP/SSOP surface mount
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Electrical Performance Boundaries: Substitute parts must operate within the supply voltage range of 1.8 V to 7 V minimum and accommodate the input bias current, input offset voltage, and output current specifications of the TC75W54FU,LF application context. The substitute part TS922IPT operates within an extended supply voltage range (2.7 V to 12 V) and provides enhanced electrical performance characteristics while maintaining dual-circuit general purpose amplifier functionality in a compatible 8-TSSOP package.

Parameter Comparison

Engineering Selection Recommendations

TC75W54FU,LF (Toshiba Semiconductor and Storage)

The TC75W54FU,LF is the primary component specification. This part is in active production status with established supply availability (6200 units in stock). The device is ROHS3 compliant and carries MSL Level 1 rating. Selection of this part is appropriate for applications requiring the specified electrical characteristics within the 1.8 V to 7 V supply range and -40°C to 85°C operating temperature window.

TS922IPT (STMicroelectronics) - Substitute Alternative

The TS922IPT is qualified as a substitute part for the TC75W54FU,LF. Both devices are ROHS3 compliant with MSL Level 1 ratings and provide dual-circuit general purpose amplifier functionality in 8-pin TSSOP surface mount packages. The TS922IPT offers extended operating temperature range (-40°C to 125°C) and higher output current capability (80 mA per channel versus 700 µA). The TS922IPT includes AEC-Q100 automotive qualification and REACH compliance documentation. The TS922IPT operates within an extended supply voltage range (2.7 V to 12 V) and provides rail-to-rail output capability. Package dimensions differ slightly (0.173" versus 0.110" width), requiring PCB layout verification for mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TS922IPT directly replace the TC75W54FU,LF in existing designs?

A: The TS922IPT provides functional equivalence as a dual-circuit general purpose amplifier in a compatible 8-TSSOP package. However, the TS922IPT package width is 4.40mm compared to the TC75W54FU,LF at 2.80mm. PCB layout and footprint compatibility must be verified before substitution. The TS922IPT operates within the TC75W54FU,LF supply voltage range and provides enhanced electrical performance.

Q: What are the key electrical differences between these parts?

A: The TS922IPT provides higher slew rate (1.3 V/µs versus 0.7 V/µs), higher gain bandwidth product (4 MHz versus 900 kHz), and significantly higher output current per channel (80 mA versus 700 µA). The TS922IPT includes rail-to-rail output capability. Both parts maintain similar input offset voltage specifications (2 mV versus 3 mV) and operate within overlapping supply voltage ranges.

Q: Are both parts RoHS compliant?

A: Both the TC75W54FU,LF and TS922IPT are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: What is the operating temperature range difference?

A: The TC75W54FU,LF operates from -40°C to 85°C. The TS922IPT extends the upper operating temperature to 125°C, providing a 40°C wider temperature window. Both parts maintain the same -40°C minimum operating temperature.

Q: Does the TS922IPT require different supply voltage considerations?

A: The TS922IPT operates within an extended supply voltage range (2.7 V to 12 V) compared to the TC75W54FU,LF (1.8 V to 7 V). Applications using the TC75W54FU,LF within its 1.8 V to 7 V range are compatible with the TS922IPT. The TS922IPT supports higher supply voltages if required by the application.

Q: What packaging considerations apply to substitution?

A: Both parts use 8-pin TSSOP surface mount packages. The TC75W54FU,LF package width is 0.110" (2.80mm). The TS922IPT package width is 0.173" (4.40mm). PCB footprint and land pattern compatibility must be confirmed before component substitution to ensure proper solder joint formation and mechanical stability.
