AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 96 pulses per revolution with commutation output in a right-angle chassis mount configuration. This encoder is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

The AMT303-V operates at 5V supply voltage with an open center actuator design (2mm to 8mm range) and terminal pin termination. Its obsolete status necessitates evaluation of active alternative models that maintain electrical and mechanical compatibility with existing applications.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Must be Incremental
• Supply Voltage: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Detent & Built-in Switch: Must match (No for both)

The substitute parts AMT313Q-V and AMT313S-V satisfy these core mechanical and electrical compatibility requirements. Both are active CUI Devices products within the AMT31 series. The primary distinction between substitutes is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses connector termination.

A key difference is that substitute parts feature programmable pulses per revolution, whereas the AMT303-V is fixed at 96 PPR. This programmability provides design flexibility for new implementations while maintaining backward compatibility through configuration.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the AMT303-V, the following selection criteria apply:

AMT313Q-V is the primary substitute when direct terminal pin termination is required. This part maintains identical electrical and mechanical interfaces while offering programmable PPR configuration. Active product status ensures long-term availability and supply chain continuity. ROHS3 compliance exceeds the original RoHS requirement.

AMT313S-V is suitable for applications where connector-based termination is acceptable or preferred. This variant provides the same core functionality and programmability as AMT313Q-V with connector termination instead of terminal pins. Active status and ROHS3 compliance apply identically.

Selection between AMT313Q-V and AMT313S-V depends solely on termination interface requirements. Both parts are functionally equivalent in all other electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

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

A: Both substitutes are mechanically and electrically compatible with the AMT303-V in terms of mounting, orientation, voltage, and actuator specifications. The primary consideration is termination style: AMT313Q-V matches the terminal pin interface of the original part, while AMT313S-V uses connector termination. Selection depends on your application's interface requirements.

Q: What is the difference between fixed and programmable pulses per revolution?

A: The AMT303-V provides a fixed 96 PPR output. The AMT313Q-V and AMT313S-V offer programmable PPR, allowing configuration to match your system requirements. If your application requires exactly 96 PPR, these substitutes can be programmed to that value.

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

A: The AMT303-V is RoHS Compliant. Both substitutes (AMT313Q-V and AMT313S-V) are ROHS3 Compliant, which represents an enhanced compliance standard. Both meet REACH Unaffected and EAR99 ECCN classifications matching the original part.

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

A: AMT313Q-V is the recommended direct replacement due to matching terminal pin termination. This minimizes interface modifications in existing designs while providing active product status and enhanced compliance.

Q: Are both substitutes currently available?

A: Yes. AMT313Q-V has 1349 units in stock, and AMT313S-V has 1045 units in stock, both listed as active products with ongoing manufacturer support.
