TC647VOATR Equivalent & Substitute Parts

Part Overview

The TC647VOATR is a brushless DC (BLDC) motor driver controller manufactured by Microchip Technology, designed for fan control applications. This device operates across a 3V to 5.5V supply voltage range and is housed in an 8-SOIC surface mount package. The TC647VOATR is classified as a pre-driver with low-side output configuration and parallel interface control, making it suitable for speed control in fan motor applications. The product maintains active status with full RoHS3 compliance and REACH unaffected certification. Alternative equivalent parts may be required due to packaging availability, inventory constraints, or specific moisture sensitivity level requirements for particular application environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC647VOATR is determined by strict equivalence across the following critical parameters: manufacturer (Microchip Technology), motor type (BLDC), function (speed controller), output configuration (pre-driver low side), interface type (parallel), package type (8-SOIC), supply voltage range (3V ~ 5.5V), operating temperature range (0°C ~ 85°C), and compliance certifications (RoHS3, REACH unaffected). Packaging format (Tape & Reel versus Tube) and moisture sensitivity level (MSL) are secondary considerations that do not affect electrical or functional compatibility but may influence procurement and storage requirements. The identified substitute parts TC647VOA and TC648VOA713 maintain full electrical and functional equivalence to the TC647VOATR across all primary parameters.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TC647VOATR, TC647VOA, and TC648VOA713—are active products from Microchip Technology with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging format requirements and moisture sensitivity level specifications for the intended application environment.

The TC647VOATR and TC648VOA713 both feature MSL 1 (unlimited moisture sensitivity), making them suitable for applications without strict moisture exposure constraints or for long-term storage without desiccant protection. Both are supplied in Tape & Reel format, which is standard for automated assembly processes.

The TC647VOA is supplied in Tube packaging with MSL 3 (168 hours), indicating a moisture sensitivity requirement of 168 hours from bag opening to soldering. This part is appropriate for applications where tube packaging is preferred or where moisture exposure during storage is controlled within the specified timeframe.

All three parts maintain identical electrical specifications, functional performance, and thermal operating ranges, ensuring direct functional interchangeability within the specified application domain.

Frequently Asked Questions (FAQ)

Q: Can TC647VOA be used as a direct replacement for TC647VOATR?

A: Yes. Both parts are electrically and functionally identical across all critical parameters including supply voltage (3V ~ 5.5V), operating temperature range (0°C ~ 85°C), BLDC motor control function, and 8-SOIC package specifications. The primary difference is packaging format (Tube versus Tape & Reel) and moisture sensitivity level (MSL 3 versus MSL 1). Selection depends on procurement requirements and storage environment conditions.

Q: What is the difference between TC648VOA713 and TC647VOATR?

A: TC648VOA713 is a parametric equivalent with identical electrical and functional specifications to TC647VOATR. Both operate at 3V ~ 5.5V supply voltage, control BLDC fan motors, and are housed in 8-SOIC packages. Both feature MSL 1 (unlimited) moisture sensitivity. The base product number differs (TC648 versus TC647), but this does not affect functional compatibility within the specified application parameters.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel versus Tube) is a procurement and handling consideration only. It does not affect the electrical characteristics, performance, or functionality of the motor driver IC. Selection should be based on assembly process requirements and inventory management practices.

Q: What does MSL 3 (168 Hours) mean for the TC647VOA?

A: MSL 3 indicates that the component must be soldered within 168 hours of opening the moisture barrier bag. This part requires controlled storage conditions and desiccant protection. If storage exceeds 168 hours, the component must be baked according to IPC standards before use. MSL 1 parts (TC647VOATR and TC648VOA713) have unlimited shelf life and do not require baking procedures.

Q: Are all three parts RoHS3 compliant?

A: Yes. TC647VOATR, TC647VOA, and TC648VOA713 are all RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

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

A: TC647VOATR and TC648VOA713 are both supplied in Tape & Reel format and are directly compatible with standard pick-and-place assembly equipment. TC647VOA is supplied in Tube format and requires manual handling or tube-compatible feeding systems. Electrical and functional performance are identical across all three parts.
