AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 1024 pulses per revolution with commutation output in a right-angle chassis mount configuration. This encoder is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The part operates at 5V supply voltage with an open center actuator design and terminal pin termination.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Incremental
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Output Type: Commutation
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts AMT313Q-V and AMT313S-V satisfy all core electrical and mechanical compatibility requirements. Both alternatives feature programmable pulses per revolution, which accommodates the fixed 1024 PPR specification of the AMT303-V. The primary distinction between substitutes lies in termination style: AMT313Q-V retains terminal pins (matching the original), while AMT313S-V uses connector termination.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing supply chain continuity for the obsolete AMT303-V. Both substitutes maintain full compliance with ROHS3 and REACH requirements, exceeding the original RoHS Compliant specification.

For applications requiring direct pin-for-pin compatibility, AMT313Q-V is the preferred substitute, maintaining terminal pin termination identical to the AMT303-V. The programmable pulses per revolution feature of AMT313Q-V allows configuration to the original 1024 PPR specification.

For applications where connector termination is acceptable or preferred, AMT313S-V provides equivalent electrical and mechanical performance with enhanced connector-based interface design.

Frequently Asked Questions (FAQ)

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

A: Both parts satisfy the core electrical and mechanical requirements. Selection depends on termination style compatibility. AMT313Q-V matches the original terminal pin configuration; AMT313S-V uses connector termination and requires interface adaptation.

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

A: The AMT313Q-V and AMT313S-V feature programmable PPR, allowing configuration to match the original 1024 PPR specification of the AMT303-V. This flexibility accommodates the fixed specification requirement.

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

A: The substitute parts meet ROHS3 Compliant status, which represents an enhanced compliance level compared to the original RoHS Compliant specification. Both maintain REACH Unaffected and EAR99 ECCN classifications.

Q: What packaging differences exist between substitute options?

A: Both AMT313Q-V and AMT313S-V are supplied in box packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: How does the open center actuator range affect substitution?

A: All three parts share identical 2mm ~ 8mm open center actuator specifications, ensuring mechanical compatibility in existing mounting configurations.
