AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 1024 pulses per revolution with 8-pole commutation output in a right-angle orientation. This component is designed for chassis mount and motor applications with a 5V supply requirement and open center actuator (2mm–8mm range).

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this encoder specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Must be Incremental
• Output Type: Must support Commutation output
• Voltage Supply: Must be 5V
• Actuator Type: Must be 2mm–8mm Open Center
• Mounting Type: Must support Chassis Mount and Motors
• Orientation: Must be Right Angle
• RoHS & REACH Compliance: Must maintain regulatory compliance

The substitute parts AMT313Q-V and AMT313S-V satisfy these core requirements. Both are active-status incremental encoders from CUI Devices with programmable pulses per revolution, allowing configuration to match the 1024 PPR specification of the AMT303-V. Both maintain identical supply voltage, actuator type, mounting configuration, and orientation. The primary distinction between substitutes is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for direct replacement of AMT303-V. It maintains terminal pin termination, matching the original interface requirement. Both components share identical electrical specifications, mounting characteristics, and regulatory compliance profiles. The AMT313Q-V is active-status, ensuring long-term availability and supply chain stability. Programmable PPR capability allows configuration to the required 1024 PPR specification.

AMT313S-V is a secondary substitute suitable only when connector-based termination is acceptable in the application design. This part introduces a termination interface change that requires PCB or harness redesign. Selection of AMT313S-V is appropriate for new designs where connector standardization provides assembly or maintenance advantages.

Both substitutes are ROHS3 compliant, representing an upgrade from the RoHS Compliant status of the obsolete AMT303-V, and maintain REACH unaffected status.

Frequently Asked Questions (FAQ)

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

A: Both parts meet the core electrical and mechanical substitution criteria. AMT313Q-V is a direct interface replacement due to matching terminal pin termination. AMT313S-V requires termination interface redesign and is not a direct drop-in replacement.

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

A: The AMT303-V has a fixed 1024 PPR specification. The AMT313Q-V and AMT313S-V feature programmable PPR, which must be configured to 1024 PPR to match the original encoder output. This programmability provides flexibility for future applications without requiring component changes.

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

A: The AMT303-V is packaged as a standard unit. AMT313Q-V is supplied in box packaging, and AMT313S-V is also supplied in box packaging. Packaging differences do not affect functional compatibility.

Q: Do the substitute parts maintain the same regulatory compliance?

A: Both substitutes maintain REACH unaffected status. The RoHS status has been upgraded from RoHS Compliant (AMT303-V) to ROHS3 Compliant (both substitutes), representing enhanced environmental compliance.

Q: What is the inventory status of these parts?

A: AMT303-V has 1067 pieces in stock but is obsolete. AMT313Q-V has 1349 pieces in stock and active status. AMT313S-V has 1045 pieces in stock and active status. Active-status substitutes ensure continued availability.
