Frequently Asked Questions (FAQ)

Q: Are SC16IS750IPW-T and SC16IS750IPW,128 pin-compatible?

A: Yes. Both components use the 24-TSSOP package with identical pin pitch (0.173") and width (4.40mm), ensuring direct PCB compatibility without layout modifications.

Q: Can SC16IS750IPW,128 replace SC16IS750IPW-T in existing designs?

A: Yes. The substitute part maintains identical electrical specifications, interface protocols (RS232, RS485, I2C, SPI, UART), supply voltage range (2.5V, 3.3V), and operating temperature range (-40°C to 95°C).

Q: What is the significance of the ",128" designation in SC16IS750IPW,128?

A: The ",128" suffix represents a packaging or manufacturing variant designation from NXP USA Inc. This does not affect functional or electrical equivalence for the specified application parameters.

Q: Are both parts ROHS3 compliant?

A: Yes. Both SC16IS750IPW-T and SC16IS750IPW,128 carry ROHS3 compliance certification with MSL rating of 1 (Unlimited moisture sensitivity level).

Q: Why is the main part number marked as obsolete?

A: Product obsolescence indicates that NXP USA Inc. has discontinued active production and support for this specific part number variant. The substitute part SC16IS750IPW,128 remains available and serves as the current equivalent for this interface controller function.
