FS210 Equivalent & Substitute Parts

Part Overview

The FS210 is an optical rotary encoder from the FlexSense® I series manufactured by TT Electronics/Optek Technology. This surface-mount, programmable digital encoder operates with quadrature (analog) output and features a vertical orientation with SMD (SMT) tab termination. The FS210 is classified as an Active product with full RoHS compliance and REACH unaffected status. Substitute parts are identified when equivalent electrical specifications, mechanical configurations, and compliance certifications align with the original component, enabling direct replacement in applications where the primary part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

The FS310 is identified as a direct substitute for the FS210 based on alignment across all critical electrical and mechanical parameters. Both components share identical specifications in the following areas:

Electrical Compatibility:

• Supply voltage range: 2.97V ~ 3.6V
• Output configuration: Digital, Quadrature (Analog)
• Pulses per revolution: Programmable

Mechanical Compatibility:

• Mounting type: Surface Mount
• Orientation: Vertical
• Termination style: SMD (SMT) Tab
• Actuator type: Codewheel Not Included
• Detent and built-in switch: Both absent

Compliance & Environmental:

• RoHS Compliant status
• Moisture Sensitivity Level: 4 (72 Hours)
• REACH Unaffected status
• Series: FlexSense® I
• Product status: Active

The primary distinction between FS210 and FS310 lies in the encoder detection method: FS210 utilizes transmissive optical sensing, while FS310 employs reflective optical sensing. Both detection methods deliver equivalent digital quadrature output performance within the specified voltage and environmental parameters.

Parameter Comparison

Engineering Selection Recommendations

FS210 Selection Criteria: The FS210 transmissive optical encoder is the primary component choice when the application requires direct light path sensing through a codewheel aperture. This configuration is suitable for applications with controlled optical environments and where the codewheel design incorporates transparent or translucent sections for light transmission.

FS310 Selection Criteria: The FS310 reflective optical encoder serves as the equivalent substitute when transmissive sensing is not feasible or when the application environment benefits from reflective surface detection. The FS310 maintains identical electrical output characteristics, supply voltage requirements, and mechanical form factor, ensuring functional equivalence in circuit integration and PCB layout.

Compliance Basis for Substitution: Both components maintain Active product status with full RoHS compliance and REACH unaffected designation. Moisture sensitivity level MSL 4 (72 Hours) applies uniformly to both parts, requiring identical handling and storage protocols. The substitution relationship is bidirectional: FS210 and FS310 are interchangeable from an electrical and mechanical standpoint, with selection determined solely by the optical sensing method required by the specific application design.
