BU6904GF-GTR Equivalent & Substitute Parts

Part Overview

The BU6904GF-GTR is a motor driver power MOSFET PWM integrated circuit manufactured by Rohm Semiconductor, designed for brushless DC (BLDC) motor applications. This device integrates control and power stages in a compact 6-SSOF surface mount package, operating across a 1.8V to 5.5V supply voltage range with 800mA output current capability. The BU6904GF-GTR is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BU6904GF-GTR are identified based on strict alignment of the following critical parameters:

• Motor driver function with fully integrated control and power stage
• Brushless DC (BLDC) motor compatibility
• Half bridge (2) output configuration
• PWM interface control
• Power MOSFET technology
• Surface mount packaging with 6-SMD, flat leads configuration
• Supply voltage range: 1.8V ~ 5.5V
• RoHS3 compliance and MSL Level 1 rating

Two active substitute parts meet these criteria: BU6909AGFT-TL (parametric equivalent) and BD69060GFT-TL (manufacturer recommended equivalent). Both parts maintain functional and electrical compatibility with the obsolete BU6904GF-GTR while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are manufactured by Rohm Semiconductor and maintain ROHS3 compliance with MSL Level 1 ratings, ensuring regulatory and environmental compatibility with the original BU6904GF-GTR.

BU6909AGFT-TL is classified as a parametric equivalent, offering identical electrical specifications including 800mA output current and -40°C to 125°C operating temperature range. The primary difference is the package variant (6-TSSOF versus 6-SSOF), which maintains mechanical compatibility while offering improved availability (193,978 units in stock). This part is recommended for direct replacement in applications where the original specifications are fully matched.

BD69060GFT-TL is the manufacturer-recommended equivalent, providing increased output current capability (1A versus 800mA) and an extended load voltage range (0.16V ~ 5V versus 1.8V ~ 5.5V). The operating temperature range is reduced to -40°C to 105°C. This part is suitable for applications requiring higher current delivery or lower load voltage operation, with substantial inventory availability (3,825 units in stock).

Frequently Asked Questions (FAQ)

Q: Can BU6909AGFT-TL directly replace BU6904GF-GTR in existing designs?

A: Yes. BU6909AGFT-TL maintains identical electrical specifications (800mA output current, 1.8V ~ 5.5V supply and load voltage, -40°C ~ 125°C operating temperature) and functional integration. The package variant change from 6-SSOF to 6-TSSOF does not affect electrical compatibility, though PCB layout verification is required to confirm mechanical fit.

Q: What are the key differences between BU6909AGFT-TL and BD69060GFT-TL?

A: BU6909AGFT-TL matches the original BU6904GF-GTR specifications exactly, including 800mA output current and identical temperature range. BD69060GFT-TL provides higher output current (1A), extended load voltage range (0.16V ~ 5V), but operates at a reduced maximum temperature (-40°C ~ 105°C). Selection depends on application current requirements and thermal operating conditions.

Q: Are package differences between 6-SSOF and 6-TSSOF significant for substitution?

A: Both packages are 6-SMD with flat leads and maintain the same footprint classification. The TSSOF variant used in substitute parts is a standard industry package. PCB layout compatibility should be verified, but electrical and mechanical substitution is valid.

Q: Do all three parts share the same compliance certifications?

A: Yes. BU6904GF-GTR, BU6909AGFT-TL, and BD69060GFT-TL are all ROHS3 compliant with MSL Level 1 ratings, ensuring equivalent environmental and regulatory compliance.

Q: Which substitute part should be selected for new designs?

A: BU6909AGFT-TL is recommended for new designs requiring exact specification matching with the original part. BD69060GFT-TL is suitable if higher output current (1A) or extended load voltage range is beneficial to the application.
