Substitute Part Grouping Explanation

Substitution eligibility for the SC16IS741IPW,118 is determined by strict equivalence across the following critical parameters:

• Package / Case: 16-TSSOP (0.173", 4.40mm Width)
• Protocol Support: RS232, RS485
• Interface Types: I2C, SPI, UART
• Voltage - Supply: 2.5V, 3.3V
• Current - Supply: 6mA
• Operating Temperature Range: -40°C ~ 95°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The identified substitute parts maintain full parametric equivalence across all specified electrical and mechanical characteristics. Both substitute parts are manufactured by NXP USA Inc. and carry Active product status, providing improved availability compared to the Obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

Both SC16IS740IPW,128 and SC16IS740IPW/Q900 are qualified substitutes for the SC16IS741IPW,118 based on complete parametric equivalence. The primary advantage of these alternatives is their Active product status, ensuring continued availability and supply chain stability.

SC16IS740IPW,128 is supplied in Tape & Reel (TR) packaging with 3900 units in current inventory. SC16IS740IPW/Q900 is also supplied in Tape & Reel (TR) packaging with 8288 units in current inventory, providing the highest stock availability.

Both substitute parts maintain identical electrical specifications, thermal operating range, interface protocols, and compliance certifications (ROHS3, REACH Unaffected). Selection between the two substitutes should be based on packaging format requirements and inventory availability for your production timeline.

Frequently Asked Questions (FAQ)

Q: Can SC16IS740IPW,128 or SC16IS740IPW/Q900 be used as direct replacements for SC16IS741IPW,118?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, interface protocols (I2C, SPI, UART), supply voltage range (2.5V to 3.3V), operating temperature range (-40°C to 95°C), and 16-TSSOP package dimensions. All three parts are ROHS3 compliant and REACH unaffected.

Q: What is the difference between SC16IS740IPW,128 and SC16IS740IPW/Q900?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary difference is packaging format designation and inventory availability. SC16IS740IPW/Q900 has higher current stock (8288 units versus 3900 units).

Q: Why is the original SC16IS741IPW,118 listed as Obsolete?

A: Obsolete status indicates the part is no longer in active production. The SC16IS740 series provides equivalent functionality with active manufacturing status, ensuring long-term supply availability.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. All three parts operate identically across the specified supply voltage range (2.5V to 3.3V), maintain the same maximum supply current (6mA), and support the full operating temperature range (-40°C to 95°C).

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

A: Yes. The identical 16-TSSOP package footprint and pin configuration allow direct substitution without PCB layout modifications.
