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 2-pole right angle orientation. This encoder is designed for chassis mount and motor applications with a 5V supply requirement and an open center actuator range of 2mm to 8mm.

The AMT303-V has reached obsolete product status. Identifying equivalent substitute parts ensures continued availability for maintenance, repair, and new production applications where this encoder specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is based on the following critical parameters that must align across parts:

• Encoder Type: Incremental operation required
• Output Type: Commutation output with 2-pole configuration
• Supply Voltage: 5V operation
• Actuator Type: 2mm to 8mm open center mechanical interface
• Mounting Configuration: Chassis mount and motor mounting compatibility
• Orientation: Right angle form factor
• Termination: Physical connection method (terminal pins or connector)

The substitute parts AMT313Q-V and AMT313S-V are qualified alternatives because they maintain these core electrical and mechanical parameters. Both substitutes feature programmable pulses per revolution, which provides functional equivalence to the fixed 500 PPR specification of the AMT303-V when configured appropriately.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V features terminal pin termination, matching the connection method of the AMT303-V. This substitute maintains identical electrical and mechanical interfaces while offering programmable PPR configuration. The part holds active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

AMT313S-V provides the same electrical and mechanical specifications as AMT313Q-V but uses connector-based termination instead of terminal pins. Selection of this variant requires accommodation for the different termination interface in the application circuit.

Both substitutes are manufactured by CUI Devices within the AMT31 series and carry REACH Unaffected and EAR99 ECCN classifications, consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V directly replace AMT303-V in existing applications?

A: Both parts maintain the same encoder type, output type, supply voltage, actuator type, mounting configuration, and orientation. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector. Electrical and mechanical compatibility is established for both variants when termination requirements are satisfied.

Q: What is the significance of programmable PPR in the substitute parts?

A: The AMT313Q-V and AMT313S-V feature programmable pulses per revolution, allowing configuration to 500 PPR to match the fixed specification of the AMT303-V. This programmability provides functional equivalence while offering flexibility for future application modifications.

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

A: The AMT303-V carries RoHS Compliant status, while both substitutes are ROHS3 Compliant. Both substitutes maintain REACH Unaffected status matching the original part. All three parts share identical moisture sensitivity level (MSL 1) and ECCN classification (EAR99).

Q: Which substitute should be selected based on termination requirements?

A: Select AMT313Q-V if the application requires terminal pin connections. Select AMT313S-V if connector-based termination is preferred or required by the circuit design. Both provide equivalent electrical performance when properly configured.

Q: What is the inventory status of these substitutes?

A: AMT313Q-V maintains 1349 pieces in stock with active product status. AMT313S-V maintains 1045 pieces in stock with active product status. Both substitutes offer established supply availability compared to the obsolete AMT303-V.
