Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT9011-CSGQWC are identified based on the following critical electrical and mechanical parameters:

• Output voltage levels: 1.2V and 3.3V fixed outputs
• Output current capability: minimum 200mA per channel
• Input voltage rating: 5.5V maximum
• Package form factor: 6-pin WDFN/WSON surface mount
• Regulatory compliance: ROHS3 and REACH compliance
• Protection features: Over-current, over-temperature, and short-circuit protection

The TLV7111233DSER from Texas Instruments meets these substitution criteria with compatible electrical specifications and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RT9011-CSGQWC and TLV7111233DSER are active production devices with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

The RT9011-CSGQWC provides higher current output capability at 300mA per channel, making it suitable for applications requiring maximum power delivery. The TLV7111233DSER offers a reduced current rating of 200mA per channel with improved dropout voltage performance and an extended operating temperature range to 125°C, plus additional under-voltage lockout (UVLO) protection.

Selection between these parts depends on application current requirements and thermal operating conditions. Both devices maintain identical output voltage levels and input voltage specifications, ensuring functional compatibility in dual-output 1.2V/3.3V power supply designs.

Frequently Asked Questions (FAQ)

Q: Can the TLV7111233DSER directly replace the RT9011-CSGQWC in all applications?

A: Direct replacement is possible when application current requirements do not exceed 200mA per channel. The TLV7111233DSER delivers lower maximum current output compared to the RT9011-CSGQWC. Verify your circuit's current draw specifications before substitution.

Q: Are the package dimensions compatible between these two parts?

A: Both parts use 6-pin WDFN/WSON surface mount packages with similar footprints. The RT9011-CSGQWC uses 6-WDFN (1.6x1.6) and the TLV7111233DSER uses 6-WSON (1.5x1.5). PCB layout compatibility requires verification of your specific design, though both packages are mechanically interchangeable for standard applications.

Q: What are the key electrical differences between these regulators?

A: The primary differences are output current capability (300mA vs. 200mA), dropout voltage performance (0.33V vs. 0.2V), quiescent current (80µA vs. 110µA), and operating temperature range (-40°C to 85°C vs. -40°C to 125°C). The TLV7111233DSER includes additional UVLO protection.

Q: Do both parts support the same output voltage configurations?

A: Yes. Both the RT9011-CSGQWC and TLV7111233DSER provide identical fixed output voltage levels of 1.2V and 3.3V with the same input voltage maximum of 5.5V.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and REACH unaffected. The TLV7111233DSER has a lower moisture sensitivity level (MSL 1 vs. MSL 3), indicating superior moisture resistance during storage and handling.
