SC16IS741IPW,112 Equivalent & Substitute Parts

Part Overview

The SC16IS741IPW,112 is a single-channel UART interface controller manufactured by NXP USA Inc., designed for RS232 and RS485 communication protocols with I2C and SPI bus interfaces. This component operates in the 16-TSSOP package format and is classified as Obsolete in product status. Due to its obsolete classification, identifying equivalent and substitute parts is essential for ongoing system maintenance, redesigns, and production continuity. The availability of active alternative models ensures design flexibility and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SC16IS741IPW,112 are identified based on strict alignment with the following critical parameters:

• Package compatibility: 16-TSSOP form factor
• Protocol support: RS232 and RS485 capability
• Interface types: I2C, SPI, and UART support
• Supply voltage range: Compatibility with 2.5V to 3.6V operation
• Supply current: Equivalent or lower current draw
• Operating temperature range: Minimum -40°C to 95°C coverage
• Regulatory compliance: ROHS3 and REACH status alignment

Two substitute parts meet these criteria: SC16IS741AIPWJ (MFR Recommended) and SC16IS740IPW,112 (Parametric Equivalent).

Parameter Comparison

Engineering Selection Recommendations

SC16IS741AIPWJ is designated as the MFR Recommended substitute. This part maintains Active product status, ensuring long-term availability and supply chain stability. It provides an expanded supply voltage range (2.3V ~ 3.6V) compared to the obsolete SC16IS741IPW,112, offering greater design flexibility for low-power applications. Both parts share identical package geometry, protocol support, and regulatory compliance certifications (ROHS3, REACH Unaffected).

SC16IS740IPW,112 serves as a Parametric Equivalent substitute. This part is also Active in product status and maintains identical electrical specifications for supply voltage (2.5V, 3.3V), current draw (6mA), and operating temperature range (-40°C ~ 95°C). The parametric alignment ensures direct functional compatibility in existing circuit designs.

Both substitutes are manufactured by NXP USA Inc. and comply with ROHS3 and REACH regulations, matching the compliance profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can SC16IS741AIPWJ be used as a direct replacement for SC16IS741IPW,112?

A: Yes. Both parts share the 16-TSSOP package, identical protocol support (RS232, RS485), and equivalent interface types (I2C, SPI, UART). The SC16IS741AIPWJ offers an extended supply voltage range (2.3V ~ 3.6V), making it suitable for the original part's operating conditions (2.5V, 3.3V).

Q: What is the difference between SC16IS741AIPWJ and SC16IS740IPW,112?

A: SC16IS741AIPWJ is the MFR Recommended substitute with expanded voltage specifications. SC16IS740IPW,112 is a Parametric Equivalent with identical electrical parameters to the original part. Both are Active products and fully compatible at the package and protocol level.

Q: Are there packaging differences between these substitutes?

A: SC16IS741AIPWJ is supplied in Cut Tape (CT) and Digi-Reel® packaging. SC16IS740IPW,112 is supplied in Tube packaging. Both use the identical 16-TSSOP case format, ensuring mechanical compatibility in PCB assembly.

Q: Do these substitutes maintain the same regulatory compliance?

A: Yes. All three parts (original and both substitutes) are ROHS3 Compliant and REACH Unaffected, with MSL rating of 1 (Unlimited). Regulatory compliance is maintained across all options.

Q: Which substitute should be selected for new designs?

A: SC16IS741AIPWJ is recommended for new designs due to its Active product status and extended voltage range, providing superior long-term availability and design margin.
