AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 500 pulses per revolution with commutation output in a right-angle chassis mount orientation. This encoder operates at 5V supply voltage and features an open center actuator design with terminal pin termination.

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring incremental encoder functionality with fixed 500 PPR output specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303-V is determined by the following critical parameters:

• Encoder Type: Incremental
• Output Type: Commutation
• Voltage - Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Detent: No
• Built in Switch: No
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute parts AMT313Q-V and AMT313S-V satisfy all mandatory compatibility parameters. Both are active CUI Devices incremental encoders with commutation output, 5V supply voltage, identical actuator and mounting specifications, and equivalent environmental compliance ratings. The primary distinction between substitutes relates to termination style and pulses per revolution configurability.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active product alternatives to the obsolete AMT303-V. Selection between substitutes depends on termination requirements and PPR configuration needs.

AMT313Q-V maintains terminal pin termination identical to the AMT303-V, providing direct mechanical and electrical compatibility for existing connector designs. This part features programmable pulses per revolution, allowing configuration to 500 PPR or alternative values as required by system specifications.

AMT313S-V provides connector-based termination, requiring interface modification from the original terminal pin design. This part also offers programmable pulses per revolution capability. Selection of this variant is appropriate when connector-based termination aligns with system architecture requirements.

Both substitutes meet current RoHS3 compliance standards and maintain equivalent environmental ratings to the original part. Active product status ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be used interchangeably with AMT303-V?

A: Both parts satisfy core functional and electrical compatibility requirements. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses connector termination. Selection depends on your system's connector interface design.

Q: What is the significance of programmable pulses per revolution in the substitute parts?

A: The AMT303-V is fixed at 500 PPR. The AMT313Q-V and AMT313S-V offer programmable PPR, allowing configuration to 500 PPR or other values. If your application requires exactly 500 PPR, both substitutes can be configured accordingly.

Q: Are there compliance differences between the original and substitute parts?

A: The AMT303-V carries RoHS Compliant status. Both substitutes meet ROHS3 Compliant standards, which represent a more current regulatory framework. Both maintain REACH Unaffected status. All three parts share identical moisture sensitivity ratings.

Q: Which substitute should I select for a direct replacement?

A: AMT313Q-V is the recommended substitute for direct mechanical and electrical replacement, as it retains terminal pin termination matching the AMT303-V. No interface modifications are required.

Q: Does termination style affect electrical performance?

A: Termination style affects mechanical integration and connector compatibility, not electrical output characteristics. Both terminal pin and connector termination deliver equivalent commutation output performance when properly interfaced.
