Engineering Selection Recommendations

TXS0104ERGYR is the primary substitute for the discontinued TXS0104ERGYRG4. Both parts are manufactured by Texas Instruments with identical electrical specifications, voltage ranges, data rates, and operating temperature ranges. The TXS0104ERGYR maintains active product status with significantly higher inventory availability (125,200 pcs) and identical packaging (14-VQFN 4.6x4.6). This part is the direct replacement for production continuity.

NTS0104BQ,115 from NXP USA Inc. is a qualified MFR recommended substitute offering enhanced performance characteristics. It supports higher data rates (50 Mbps versus 24 Mbps) and extended operating temperature range (-40°C ~ 125°C). The package footprint differs (14-DHVQFN 2.5x3 versus 14-VQFN 4.6x4.6), requiring PCB layout verification. MSL rating is superior (1 versus 2). This part is suitable for applications requiring higher bandwidth or extended temperature operation.

UM3204Q and UM3204QS from Union Semiconductor International Limited are parametric equivalents meeting all critical electrical specifications. Both maintain identical voltage ranges, data rates, and operating temperatures. Package designation differs (14-QFN versus 14-VQFN), though physical dimensions remain equivalent (4.6x4.6). MSL rating is lower (3 versus 2), requiring stricter moisture control during storage and assembly. These parts are suitable for cost-optimized designs where auto-direction sensing feature is not required.

Selection priority: TXS0104ERGYR for direct replacement; NTS0104BQ,115 for enhanced performance requirements; UM3204Q or UM3204QS for parametric equivalence with cost considerations.

Frequently Asked Questions (FAQ)

Q: Can TXS0104ERGYR be used as a direct replacement for TXS0104ERGYRG4?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, voltage ranges (VCCA 1.65 V ~ 3.6 V, VCCB 2.3 V ~ 5.5 V), data rates (24 Mbps), operating temperature (-40°C ~ 85°C), and package footprint (14-VQFN 4.6x4.6). No circuit modifications are required.

Q: What are the key differences between NTS0104BQ,115 and the original TXS0104ERGYRG4?

A: NTS0104BQ,115 offers higher data rate capability (50 Mbps versus 24 Mbps) and extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C). The package footprint differs (14-DHVQFN 2.5x3 versus 14-VQFN 4.6x4.6), requiring PCB layout verification. Voltage ranges and channel configuration remain identical.

Q: Are UM3204Q and UM3204QS suitable for all applications using TXS0104ERGYRG4?

A: UM3204Q and UM3204QS meet all critical electrical parameters but lack the auto-direction sensing feature. Package designation differs (14-QFN versus 14-VQFN), though physical dimensions are equivalent. MSL rating is lower (3 versus 2), requiring stricter moisture control. These parts are suitable for applications where auto-direction sensing is not required.

Q: What is the impact of different MSL ratings on component selection?

A: MSL (Moisture Sensitivity Level) determines storage and handling requirements. TXS0104ERGYRG4 and TXS0104ERGYR have MSL 2 (1 Year shelf life). NTS0104BQ,115 has MSL 1 (Unlimited shelf life), offering superior moisture tolerance. UM3204Q and UM3204QS have MSL 3 (168 Hours), requiring more stringent moisture control and shorter storage windows.

Q: Can NTS0104BQ,115 be used in applications designed for 24 Mbps operation?

A: Yes. NTS0104BQ,115 supports data rates up to 50 Mbps, which exceeds the 24 Mbps requirement. The higher bandwidth capability does not create compatibility issues in lower-speed applications. However, PCB layout must accommodate the different package footprint (14-DHVQFN 2.5x3).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TXS0104ERGYR, NTS0104BQ,115, UM3204Q, and UM3204QS are all ROHS3 compliant, meeting environmental and regulatory requirements equivalent to the original TXS0104ERGYRG4.
