SC16IS741IPW,128 Equivalent & Substitute Parts

Part Overview

The SC16IS741IPW,128 is a single-channel UART interface controller manufactured by NXP USA Inc., designed for RS232 and RS485 communication protocols with I2C, SPI, and UART interface support. This component operates at supply voltages of 2.5V and 3.3V with a maximum supply current of 6mA and is housed in a 16-TSSOP package.

The SC16IS741IPW,128 is classified as obsolete. Due to its discontinued status, equivalent and substitute parts from the active product line are necessary for new designs and ongoing production requirements. Substitute components must maintain compatibility across electrical parameters, interface protocols, package specifications, and compliance certifications.

Substitute Part Grouping Explanation

Substitute parts for the SC16IS741IPW,128 are classified based on the following substitution criteria:

MFR Recommended Substitute: SC16IS741AIPWJ

• Maintains identical base product number (SC16IS741) with enhanced specification variant
• Supports identical protocols (RS232, RS485) and interfaces (I2C, SPI, UART)
• Operates within compatible voltage range (2.3V ~ 3.6V, encompassing the original 2.5V, 3.3V specification)
• Housed in identical 16-TSSOP package
• Active product status with full compliance certifications

Parametric Equivalents: SC16IS740IPW,128 and SC16IS740IPW/Q900,

• Share identical electrical parameters: voltage supply (2.5V, 3.3V), current supply (6mA), operating temperature range (-40°C ~ 95°C)
• Support identical protocols (RS232, RS485) and interfaces (I2C, SPI, UART)
• Identical package specification (16-TSSOP)
• Both maintain active product status with full compliance certifications
• Differ only in base product number (SC16IS740 vs. SC16IS741) and packaging format (Tape & Reel vs. Cut Tape)

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can SC16IS741AIPWJ directly replace SC16IS741IPW,128 in existing designs? A: Yes. Both components share identical package specifications (16-TSSOP), protocol support (RS232, RS485), and interface capabilities (I2C, SPI, UART). The SC16IS741AIPWJ operates within an expanded voltage range (2.3V ~ 3.6V) that encompasses the original specification (2.5V, 3.3V), ensuring full compatibility.

Q: What is the difference between SC16IS740IPW,128 and SC16IS740IPW/Q900,? A: Both parts are parametric equivalents with identical electrical specifications, operating temperature range, and package configuration. The primary difference is packaging format: SC16IS740IPW,128 is supplied in Tape & Reel (TR) format, while SC16IS740IPW/Q900, is also supplied in Tape & Reel (TR) format. Both maintain active product status and full compliance certifications.

Q: Are all substitute parts RoHS3 compliant? A: Yes. SC16IS741AIPWJ, SC16IS740IPW,128, and SC16IS740IPW/Q900, are all ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH unaffected status, matching the original SC16IS741IPW,128 compliance profile.

Q: Which substitute part should be selected for new production designs? A: SC16IS741AIPWJ is the manufacturer-recommended substitute for new designs. It maintains the SC16IS741 base product lineage with active product status and offers the widest voltage operating range (2.3V ~ 3.6V). SC16IS740 variants are suitable alternatives when base product number differentiation is not a design requirement.

Q: Is the 16-TSSOP package identical across all substitute parts? A: Yes. All substitute parts utilize the identical 16-TSSOP package specification (0.173", 4.40mm Width), enabling direct PCB layout compatibility without redesign requirements.
