AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 400 pulses per revolution with commutation output in a 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 is necessary to maintain system compatibility and ensure continued availability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

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

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

The substitute parts AMT313Q-V and AMT313S-V share these core electrical and mechanical characteristics with the AMT303-V. Both substitutes feature programmable pulses per revolution capability, which provides functional equivalence to the fixed 400 PPR configuration of the main part. The key distinction between substitutes lies in termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active product alternatives to the obsolete AMT303-V. Selection between these substitutes depends on termination interface requirements:

AMT313Q-V maintains terminal pin termination identical to the original AMT303-V, providing direct mechanical and electrical compatibility for existing connector designs. This part is recommended for applications requiring minimal PCB or harness redesign.

AMT313S-V features connector-based termination, requiring interface modification but offering standardized connector integration for new designs. This part is suitable for applications where connector-based termination is preferred or already established.

Both substitutes carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The programmable pulses per revolution feature in both substitutes provides operational flexibility beyond the fixed 400 PPR specification of the original part.

Frequently Asked Questions (FAQ)

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

A: Both parts share identical electrical and mechanical specifications including encoder type, output type, supply voltage, actuator type, mounting type, and orientation. The primary difference is termination style. AMT313Q-V uses terminal pins matching the original; AMT313S-V uses a connector interface. Selection depends on your application's termination requirements.

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

A: The AMT303-V operates at a fixed 400 PPR configuration. The AMT313Q-V and AMT313S-V feature programmable PPR capability, allowing configuration to 400 PPR or other values as needed. This provides functional equivalence and operational flexibility for the fixed specification of the original part.

Q: Are there compliance differences between the main part and substitutes?

A: The AMT303-V carries RoHS Compliant status. Both substitutes carry ROHS3 Compliant status, representing an updated compliance standard. All three parts maintain REACH Unaffected status and identical moisture sensitivity levels.

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

A: AMT313Q-V is the direct replacement option, maintaining terminal pin termination identical to the AMT303-V. No connector interface modifications are required for this substitution.

Q: What packaging is available for the substitute parts?

A: Both AMT313Q-V and AMT313S-V are supplied in box packaging.
