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 specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V must satisfy the following critical parameters to ensure functional compatibility:

• Encoder Type: Incremental
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• RoHS and REACH Compliance

The AMT313Q-V and AMT313S-V are listed as equivalent substitutes. Both parts maintain the core electrical and mechanical specifications required for direct replacement. The primary distinction between these substitutes is the pulses per revolution capability (programmable versus fixed) and termination style (terminal pins versus connector).

Parameter Comparison

Engineering Selection Recommendations

The AMT303-V is obsolete; therefore, substitution with an active product is necessary for new designs and ongoing procurement.

Both AMT313Q-V and AMT313S-V are active products with ROHS3 compliance, providing improved regulatory alignment compared to the original RoHS Compliant designation of the AMT303-V. Both substitutes maintain identical electrical supply voltage, mechanical mounting configuration, and actuator specifications.

Selection between AMT313Q-V and AMT313S-V depends on termination requirements: AMT313Q-V provides terminal pin termination matching the original AMT303-V, while AMT313S-V provides connector termination. The programmable pulses per revolution feature in both substitutes allows configuration to match the original 500 PPR specification of the AMT303-V.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V directly replace AMT303-V without circuit modifications?

A: Both substitutes maintain identical supply voltage (5V), mounting type (Chassis Mount, Motors), orientation (Right Angle), and actuator specifications (2mm ~ 8mm Open Center). The primary consideration is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector. Circuit compatibility depends on your existing termination interface.

Q: What is the difference between fixed 500 PPR and programmable PPR?

A: The AMT303-V provides fixed 500 pulses per revolution. The AMT313Q-V and AMT313S-V offer programmable PPR, allowing configuration to 500 PPR or other values as required by your application. If your system requires exactly 500 PPR, both substitutes can be programmed to this specification.

Q: Are there packaging differences between these parts?

A: AMT303-V packaging is listed as standard. AMT313Q-V and AMT313S-V are supplied in Box packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do the substitute parts meet the same compliance standards?

A: Both AMT313Q-V and AMT313S-V are ROHS3 Compliant and REACH Unaffected, providing equivalent or improved regulatory compliance compared to the RoHS Compliant AMT303-V. Both share the same ECCN (EAR99) and HTSUS (8543.70.4500) classifications.

Q: Which substitute should I select for new designs?

A: For applications requiring terminal pin termination, select AMT313Q-V. For applications requiring connector termination, select AMT313S-V. Both are active products with current inventory availability and support programmable configuration to match your original 500 PPR requirement.
