RT6575DGQW(2) Equivalent & Substitute Parts

Part Overview

The RT6575DGQW(2) is a Power Management Integrated Circuit (PMIC) manufactured by Richtek USA Inc., classified as a voltage regulator with linear switching topology. This device integrates four independent outputs: two synchronous step-down (buck) regulators and two linear low-dropout (LDO) regulators, operating at switching frequencies of 300kHz and 355kHz. The component is housed in a 20-pin WQFN package with exposed pad and is designed for surface mount applications.

The RT6575DGQW(2) is currently in active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the device family, enabling direct replacement in applications where component availability or procurement requirements necessitate alternative part selection.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT6575DGQW(2) are identified based on strict parametric equivalence across the following critical criteria:

Electrical Parameters:

• Identical topology: Step-Down (Buck) Synchronous (2) and Linear (LDO) (2)
• Matching number of outputs: 4
• Identical switching frequencies: 300kHz and 355kHz
• Equivalent output voltage ranges and configurations
• Identical supply voltage range: 5V ~ 25V
• Matching operating temperature range: -40°C ~ 85°C

Mechanical Parameters:

• Identical package type: 20-WQFN (3x3) with exposed pad
• Surface mount mounting type
• Identical MSL rating: 3 (168 Hours)

Compliance & Regulatory:

• ROHS3 compliance maintained
• REACH unaffected status maintained
• Identical ECCN and HTSUS classifications

Substitutes are grouped by packaging configuration (Cut Tape vs. Tape & Reel) and base product number variants (RT6575 vs. RT6576 series). All listed substitutes maintain full electrical and mechanical compatibility with the primary part.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the RT6575DGQW(2) primary part number. Selection among equivalent parts is determined by packaging and procurement requirements rather than functional differences.

RT6575BGQW: This part is electrically and mechanically identical to the RT6575DGQW(2) and is available in Cut Tape (CT) & Digi-Reel® packaging format. This variant is suitable for applications requiring smaller quantity procurement or manual assembly processes.

RT6575BGQW(2): This part maintains identical electrical specifications and is supplied in Tape & Reel (TR) packaging format. The (2) designation indicates reel packaging configuration, appropriate for high-volume automated assembly operations.

RT6576DGQW(2): This part represents an alternative base product number within the Richtek PMIC family. It maintains all electrical parameters, switching frequencies, output configurations, and operating characteristics identical to the RT6575DGQW(2). The RT6576 variant is supplied in Tape & Reel (TR) format and is suitable for applications where the alternative base product number is acceptable within design specifications.

All substitute parts carry identical RoHS3 compliance, REACH unaffected status, and MSL ratings. Product status is active for all listed alternatives, ensuring continued availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can RT6575BGQW be used as a direct replacement for RT6575DGQW(2)?

A: Yes. The RT6575BGQW is electrically and mechanically identical to the RT6575DGQW(2). The primary difference is packaging format: RT6575BGQW is supplied in Cut Tape (CT) & Digi-Reel® format, while RT6575DGQW(2) is supplied in Cut Tape (CT) & Digi-Reel® format. Both are suitable for direct substitution in circuit applications.

Q: What is the difference between RT6575BGQW and RT6575BGQW(2)?

A: Both parts are electrically identical with matching topology, output configurations, and operating parameters. The distinction is packaging format: RT6575BGQW is available in Cut Tape (CT) & Digi-Reel® format, while RT6575BGQW(2) is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements and procurement volume.

Q: Is RT6576DGQW(2) compatible with RT6575DGQW(2) applications?

A: Yes. The RT6576DGQW(2) maintains identical electrical specifications, including topology, output voltage ranges, switching frequencies, supply voltage range, and operating temperature. Both parts are housed in 20-WQFN (3x3) packages with exposed pads and are suitable for direct substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and REACH unaffected status, matching the primary RT6575DGQW(2) part number.

Q: What is the MSL rating for these parts?

A: All parts in this family, including RT6575DGQW(2) and all substitutes, carry an MSL rating of 3 with a moisture sensitivity duration of 168 hours.

Q: Can these parts be used interchangeably in automated assembly?

A: Parts supplied in Tape & Reel (TR) format, including RT6575BGQW(2) and RT6576DGQW(2), are optimized for automated pick-and-place assembly.
