TC649VOATR Equivalent & Substitute Parts

Part Overview

The TC649VOATR is a motor driver integrated circuit manufactured by Microchip Technology, designed for brushless DC (BLDC) motor speed control applications. This device operates across a 3V to 5.5V supply voltage range and is packaged in an 8-SOIC surface mount configuration. The TC649VOATR is classified as a pre-driver with low-side output configuration and parallel interface, making it suitable for fan controller applications. The product maintains active status with full RoHS3 compliance and unlimited moisture sensitivity level rating. Identifying equivalent substitute parts becomes necessary when managing inventory constraints, ensuring supply chain continuity, or optimizing procurement across multiple production batches.

Key Parameters

Substitute Part Grouping Explanation

The TC648VOA713 qualifies as a parametric equivalent to the TC649VOATR based on strict alignment across all critical electrical and mechanical parameters. Both devices share identical specifications for motor type (Brushless DC), functional classification (Speed Controller), output configuration (Pre-Driver - Low Side), interface type (Parallel), supply voltage range (3V ~ 5.5V), operating temperature range (0°C ~ 85°C), and physical packaging (8-SOIC surface mount). Both parts maintain equivalent compliance certifications including ROHS3 compliance, unlimited moisture sensitivity level, and identical ECCN and HTSUS classifications. The substitution relationship is based exclusively on these matching parameters: identical electrical performance envelope, compatible pinout and package geometry, and equivalent regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the TC649VOATR and TC648VOA713 maintain active product status with full regulatory compliance. Selection between these parts should be based on inventory availability and procurement lead times. The TC649VOATR currently maintains 2830 pieces in stock, while the TC648VOA713 maintains 2313 pieces in stock. Both parts carry identical ROHS3 compliance certification and REACH unaffected status, ensuring equivalent environmental and regulatory compliance for applications requiring these certifications. The identical electrical specifications, package geometry, and compliance profile establish these parts as direct functional equivalents for BLDC motor speed control applications operating within the 3V to 5.5V supply range.

Frequently Asked Questions (FAQ)
