Engineering Selection Recommendations

For Direct Replacement (Obsolete to Active Transition):

XR68C192CV-F is the primary direct substitute. It maintains identical electrical specifications, package footprint, and supply voltage range while offering active product status and improved long-term availability. This part is suitable for designs requiring no circuit modifications.

XR68C192IV-F provides equivalent functionality with ROHS3 compliance certification, offering enhanced environmental compliance documentation for regulated applications.

For Parametric Equivalence with Same Manufacturer:

XR88C192CV-F delivers identical functional performance and active status. The base product number change (XR88C192 vs. XR68C192) reflects internal MaxLinear product line organization but does not affect electrical or mechanical compatibility.

For Cross-Manufacturer Alternatives:

TL28L92FR and TL28L92IFR (Texas Instruments) offer enhanced data rate capability (1 Mbps vs. 230.4 kbps) and additional modem control and false start bit detection features. These parts require verification of supply voltage compatibility, as they operate at 3.3V and 5V discrete levels rather than the continuous 2.97V ~ 5.5V range of MaxLinear parts. Both parts carry ROHS3 and REACH compliance certifications. TL28L92IFR offers significantly higher inventory availability (65,780 units).

Compliance Considerations:

All substitute parts maintain MSL 3 rating and RoHS compliance. Parts designated ROHS3 (XR68C192IV-F, TL28L92FR, TL28L92IFR) provide enhanced compliance documentation suitable for regulated industries.

Frequently Asked Questions (FAQ)

Q: Can XR68C192CV-F be used as a direct replacement for XR68C92CV-F?

A: Yes. XR68C192CV-F is a direct substitute with identical electrical specifications, package footprint (44-LQFP 10x10), supply voltage range (2.97V ~ 5.5V), and functional parameters. The primary advantage is active product status, ensuring continued availability and support.

Q: What is the difference between XR68C192CV-F and XR68C192IV-F?

A: Both parts are electrically and mechanically identical. The primary difference is RoHS certification level: XR68C192CV-F carries RoHS Compliant status, while XR68C192IV-F carries ROHS3 Compliant status. ROHS3 provides enhanced compliance documentation for regulated applications.

Q: Can Texas Instruments TL28L92 series parts replace MaxLinear XR68C92CV-F?

A: TL28L92FR and TL28L92IFR are functionally compatible as dual-channel UART ICs with 16-byte FIFOs in 44-pin packages. However, they differ in supply voltage specification (3.3V and 5V discrete levels vs. 2.97V ~ 5.5V continuous range) and offer enhanced features (modem control, false start bit detection, 1 Mbps data rate). Circuit verification is required to confirm voltage compatibility before substitution.

Q: What is the difference between 44-LQFP and 44-QFP packaging?

A: Both are 44-pin surface-mount packages with 10x10 mm footprints and identical pin spacing. LQFP (Low-profile Quad Flat Package) and QFP (Quad Flat Package) are mechanically compatible for PCB layout purposes. Verify component height specifications if space constraints exist.

Q: Which substitute part offers the best long-term availability?

A: TL28L92IFR (Texas Instruments) currently has the highest inventory level (65,780 units). Among MaxLinear parts, XR68C192CV-F (1,498 units) and XR68C192IV-F (1,355 units) offer active status with established supply chains.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry either RoHS Compliant or ROHS3 Compliant certification. ROHS3 designation indicates enhanced compliance documentation suitable for regulated industries.

Q: What is the maximum data rate for each substitute part?

A: MaxLinear parts (XR68C92CV-F, XR68C192CV-F, XR68C192IV-F, XR88C192CV-F) support 230.4 kbps maximum data rate. Texas Instruments parts (TL28L92FR, TL28L92IFR) support 1 Mbps maximum data rate, providing higher-speed capability for applications requiring faster serial communication.
