Engineering Selection Recommendations

MAX13042EEBC+T (Analog Devices Inc./Maxim Integrated): This substitute offers the highest data rate performance at 100 Mbps, exceeding the original specification. The part is active in production status, ensuring long-term availability. ROHS3 compliance is maintained. Note that VCCB voltage range is narrower (2.2 V ~ 3.6 V) compared to the original part, which may limit application flexibility in systems requiring the full 5.5 V upper limit. Package configuration differs (12-WFBGA, CSPBGA vs. 12-UFBGA), requiring PCB layout evaluation.

NTS0104GU12,115 (NXP USA Inc.): This substitute maintains identical VCCA and VCCB voltage ranges as the original part, providing direct electrical compatibility. Data rate capability is 50 Mbps, exceeding the 24 Mbps requirement. The part is active in production with ROHS3 compliance. Operating temperature range extends to 125°C, offering broader thermal performance. Package configuration is 12-XFQFN (2x1.7), differing from the original 12-UFBGA, requiring PCB redesign considerations. Auto-direction sensing feature is preserved.

Frequently Asked Questions (FAQ)

Q: Can MAX13042EEBC+T be used in applications requiring 5.5 V on VCCB? A: No. The MAX13042EEBC+T maximum VCCB voltage is 3.6 V, which does not support the original part's 5.5 V upper limit. Application voltage requirements must be evaluated before selection.

Q: What are the package differences between substitute parts and the original? A: The TXS0104EZXUR uses 12-UFBGA packaging. MAX13042EEBC+T uses 12-WFBGA or CSPBGA. NTS0104GU12,115 uses 12-XFQFN (2x1.7). Each package has different footprint and land pattern requirements, necessitating PCB layout modifications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. Both substitute parts and the original TXS0104EZXUR are ROHS3 compliant, meeting environmental regulatory requirements.

Q: Which substitute part offers the best data rate performance? A: MAX13042EEBC+T provides 100 Mbps, the highest among all options. NTS0104GU12,115 provides 50 Mbps. Both exceed the original 24 Mbps specification.

Q: Does NTS0104GU12,115 retain the auto-direction sensing feature? A: Yes. NTS0104GU12,115 includes auto-direction sensing, matching the original TXS0104EZXUR functionality.

Q: What is the inventory status of substitute parts? A: MAX13042EEBC+T has 3,178 pieces in stock. NTS0104GU12,115 has 3,100 pieces in stock. Both are available for immediate procurement.
