TC647BEUATR Equivalent & Substitute Parts

Part Overview

The TC647BEUATR is an active Brushless DC (BLDC) motor driver controller manufactured by Microchip Technology, designed for fan control applications. Operating across a 3V to 5.5V supply voltage range, this surface-mount integrated circuit functions as a speed controller with pre-driver low-side output configuration using parallel interface architecture. The device is housed in an 8-MSOP package and is ROHS3 compliant with MSL Level 1 rating, indicating unlimited moisture sensitivity protection. Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain disruptions, or specific packaging requirements for production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC647BEUATR is determined by strict adherence to the following parameters:

• Manufacturer: Must be Microchip Technology
• Base Product Number: Must be TC647
• Motor Type: Must support Brushless DC (BLDC)
• Function: Must provide speed controller functionality
• Output Configuration: Must be pre-driver low side
• Interface: Must use parallel interface
• Voltage Supply Range: Must operate within 3V ~ 5.5V
• Operating Temperature Range: Must support -40°C ~ 85°C
• Package Type: Must be 8-MSOP or equivalent 8-TSSOP footprint
• Mounting Type: Must be surface mount
• Compliance: Must maintain ROHS3 and REACH Unaffected status

The TC647BEUA qualifies as a direct substitute based on identical electrical specifications, thermal performance, and functional characteristics. The primary difference is packaging format: TC647BEUATR is supplied in tape and reel format, while TC647BEUA is supplied in tube packaging.

Parameter Comparison

Engineering Selection Recommendations

Both TC647BEUATR and TC647BEUA are active products from Microchip Technology with identical electrical and thermal specifications. Selection between these parts should be based on packaging and storage requirements:

TC647BEUATR (Tape & Reel): Suitable for high-volume automated assembly operations. MSL Level 1 rating provides unlimited shelf life without moisture exposure concerns. Recommended for production environments with continuous component usage.

TC647BEUA (Tube): Suitable for lower-volume applications, prototyping, or manual assembly processes. MSL Level 2 rating requires storage within controlled humidity conditions (1-year shelf life from manufacturing date). Recommended for development environments or applications with extended storage intervals between assembly operations.

Both parts maintain full ROHS3 compliance and REACH Unaffected status, ensuring regulatory compliance across global markets. No functional or electrical compromises exist between these variants.

Frequently Asked Questions (FAQ)

Q: Can TC647BEUA be used as a direct replacement for TC647BEUATR in production assembly?

A: Yes, from an electrical and functional standpoint. However, packaging format differences require process adaptation. Tape & reel format (TC647BEUATR) integrates directly with pick-and-place equipment, while tube format (TC647BEUA) requires manual feeding or tube-compatible feeders. Moisture sensitivity level differences (MSL 1 vs MSL 2) may impact storage and handling procedures.

Q: What is the significance of the MSL rating difference between these parts?

A: MSL Level 1 (TC647BEUATR) indicates unlimited moisture sensitivity protection, allowing indefinite storage without desiccant packaging. MSL Level 2 (TC647BEUA) requires controlled storage conditions with a 1-year shelf life from manufacturing date. For applications with extended storage periods, TC647BEUATR is the preferred choice.

Q: Are the package footprints identical between TC647BEUATR and TC647BEUA?

A: Yes. Both parts use the 8-MSOP (8-TSSOP) package with 0.118" width and 3.00mm dimensions. PCB layout, solder pad configuration, and component placement are identical. No design modifications are required when substituting between these parts.

Q: Do both parts support the same BLDC motor control applications?

A: Yes. Both TC647BEUATR and TC647BEUA provide identical speed controller functionality for Brushless DC motors with parallel interface architecture. Fan controller applications operate identically across both variants.

Q: What compliance certifications apply to both substitute parts?

A: Both parts maintain ROHS3 compliance and REACH Unaffected status. ECCN classification is EAR99 for both variants, and HTSUS code 8542.31.0001 applies to both parts.
