TC647EOATR Equivalent & Substitute Parts

Part Overview

The TC647EOATR is a Brushless DC (BLDC) motor driver controller manufactured by Microchip Technology, part of the FanSense™ series. This integrated circuit functions as a speed controller with pre-driver low-side output configuration, designed for fan control applications. The device operates across a 3V to 5.5V supply voltage range and is housed in an 8-SOIC surface mount package. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, the TC647EOATR remains in production. Equivalent and substitute parts are identified based on matching electrical specifications, package geometry, and functional parameters to support design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC647EOATR is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Voltage supply range: 3V ~ 5.5V
• Motor type: Brushless DC (BLDC)
• Function: Speed controller
• Output configuration: Pre-Driver - Low Side
• Interface: Parallel

Mechanical Compatibility Criteria:

• Package type: 8-SOIC
• Package dimensions: 0.154" width (3.90mm)
• Mounting type: Surface Mount

Compliance & Certification:

• RoHS3 compliance
• REACH unaffected status
• ECCN: EAR99
• HTSUS: 8542.31.0001

Substitute parts are grouped into two categories: direct packaging equivalents (differing only in tape format) and parametric equivalents (matching all electrical and mechanical specifications with minor variations in moisture sensitivity rating).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and functional equivalence to the TC647EOATR within the specified operating parameters. Selection between alternatives should be based on the following factors:

Packaging Format Considerations: TC647EOA is supplied in tube packaging, suitable for manual assembly or lower-volume production runs. TC647EOATR and TC647BEOATR are supplied in tape and reel format, optimized for automated pick-and-place assembly. TC642EOA713 is supplied in cut tape format for intermediate volume applications.

Moisture Sensitivity Level: TC647EOATR and TC647EOA carry MSL rating 1 (unlimited shelf life without baking). TC647BEOATR and TC642EOA713 carry MSL rating 3 (168-hour maximum floor life before baking requirement). Selection depends on storage and handling protocols in your manufacturing environment.

Product Status & Availability: All parts maintain active product status with ROHS3 compliance and REACH unaffected certification. Inventory levels vary; TC647EOA offers the highest stock availability at 2131 units.

Base Product Number Variants: TC647EOATR and TC647BEOATR share base product number TC647. TC642EOA713 uses base product number TC642. Both base products are functionally equivalent for BLDC speed control applications within the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can TC647EOA be used as a direct replacement for TC647EOATR? A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: TC647EOA uses tube packaging while TC647EOATR uses tape and reel. Selection depends on assembly process requirements.

Q: What is the difference between TC647EOATR and TC647BEOATR? A: Both are tape and reel packaged. The primary difference is moisture sensitivity level: TC647EOATR has MSL 1 (unlimited shelf life), while TC647BEOATR has MSL 3 (requires baking after 168 hours of floor exposure). Electrical specifications are identical.

Q: Is TC642EOA713 fully compatible with TC647EOATR? A: TC642EOA713 matches all critical electrical and mechanical parameters: voltage supply range, motor type, function, package geometry, and operating temperature. The base product number differs (TC642 vs TC647), but functional equivalence is maintained for BLDC speed control applications. MSL rating is 3 (168 hours).

Q: What does the "713" suffix in TC642EOA713 indicate? A: The "713" suffix indicates cut tape packaging format. This part is supplied on cut tape rather than full reel or tube, suitable for intermediate production volumes.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts carry ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements.

Q: Which substitute part offers the best inventory availability? A: TC647EOA offers the highest stock level at 2131 units. TC647BEOATR follows with 2815 units. Selection should balance packaging format requirements with availability.

Q: Can these parts be used interchangeably in high-reliability applications? A: All parts maintain identical electrical specifications and active product status. Interchangeability depends on specific moisture sensitivity and packaging requirements of your application. Verify MSL handling protocols match your manufacturing environment.
