AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 200 pulses per revolution with commutation output in a right-angle chassis mount orientation. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs. Substitute parts must maintain compatibility across electrical specifications, mechanical form factor, and output characteristics to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on the following critical parameters that define functional equivalence:

• Encoder Type: Incremental operation
• Supply Voltage: 5V compatibility
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Output Type: Commutation-based output
• Termination compatibility: Terminal Pins or Connector variants

The AMT313Q-V and AMT313S-V are classified as substitutes because they maintain all core mechanical and electrical parameters. The primary distinction is that these alternatives feature programmable pulses per revolution, allowing configuration to 200 PPR to match the fixed 200 PPR specification of the AMT303-V. Both substitute parts are active products with current manufacturing status, addressing the obsolescence of the original component.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are suitable replacements for the obsolete AMT303-V based on compliance and product status criteria:

• AMT313Q-V: Maintains terminal pin termination identical to the original AMT303-V, providing direct mechanical compatibility. ROHS3 compliance exceeds the RoHS Compliant status of the original part. Active product status ensures long-term availability and supply chain continuity.

• AMT313S-V: Offers connector-based termination as an alternative to terminal pins. ROHS3 compliance and active product status provide equivalent regulatory and availability advantages. Selection depends on system integration requirements regarding termination method.

Both alternatives support programmable pulse-per-revolution configuration, enabling direct functional equivalence to the fixed 200 PPR specification of the AMT303-V through firmware or hardware configuration during integration.

Frequently Asked Questions (FAQ)

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

A: Both parts are functionally equivalent when configured to 200 PPR. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface. Selection depends on your system's termination requirements.

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 200 PPR to match the fixed specification of the AMT303-V. This flexibility provides functional equivalence while offering design advantages for future applications requiring different resolution settings.

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

A: The substitute parts carry ROHS3 compliance, which represents an updated regulatory standard compared to the RoHS Compliant designation of the AMT303-V. Both maintain REACH Unaffected status and MSL 1 (Unlimited) ratings, ensuring equivalent environmental and moisture handling characteristics.

Q: Why is the AMT303-V classified as obsolete?

A: Obsolescence indicates the part is no longer in active production. The AMT313Q-V and AMT313S-V are active products from the same manufacturer, providing current alternatives with enhanced specifications and guaranteed supply availability.

Q: Does termination style affect electrical performance?

A: Termination style affects mechanical integration and connection methodology but does not alter electrical performance. Both terminal pin and connector terminations deliver identical commutation output characteristics and 5V supply voltage compatibility.
