AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 800 pulses per revolution with commutation output in counter-clockwise direction and 20-pole 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 is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is determined by the following critical parameters that must remain consistent:

• Encoder Type: Incremental (fixed requirement)
• Voltage Supply: 5V (fixed requirement)
• Actuator Type: 2mm–8mm Open Center (fixed requirement)
• Mounting Type: Chassis Mount, Motors (fixed requirement)
• Orientation: Right Angle (fixed requirement)
• Output Type: Commutation (fixed requirement)
• Pulses per Revolution: 800 (primary specification) or Programmable (acceptable alternative)

The substitute parts AMT313Q-V and AMT313S-V meet all mandatory electrical and mechanical parameters. Both are active-status components from CUI Devices with programmable pulse-per-revolution capability, allowing configuration to match the 800 PPR specification of the original AMT303-V. The key difference between substitutes is 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-status components with current manufacturing support, providing superior long-term availability compared to the obsolete AMT303-V. Both substitutes maintain full compliance with RoHS3 and REACH regulations.

AMT313Q-V is the preferred direct substitute when terminal pin termination is required in the application. The programmable pulse-per-revolution feature allows configuration to the 800 PPR specification of the original part without design modification.

AMT313S-V is suitable for applications where connector-based termination is acceptable or preferred. The connector interface may simplify integration in modular or field-replaceable designs.

Selection between the two substitutes depends solely on termination interface requirements of the target application. Both provide equivalent electrical performance and mechanical compatibility with the AMT303-V specification envelope.

Frequently Asked Questions (FAQ)

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

A: Both substitutes are electrically and mechanically compatible with the AMT303-V when configured to 800 PPR. The primary difference is termination style: AMT313Q-V uses terminal pins (direct match to original), while AMT313S-V uses a connector. Selection depends on the application's termination interface requirements.

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

A: The AMT313Q-V and AMT313S-V feature programmable PPR capability, allowing the encoder to be configured to output 800 pulses per revolution to match the AMT303-V specification. This eliminates the need for design changes when transitioning from the obsolete part.

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

A: The AMT303-V is RoHS Compliant, while both substitutes are ROHS3 Compliant, representing an enhanced compliance standard. Both maintain REACH Unaffected status. The substitutes meet or exceed the regulatory requirements of the original part.

Q: Why is the AMT303-V classified as obsolete?

A: Obsolescence indicates the part is no longer in active production. The AMT313Q-V and AMT313S-V are active-status alternatives that provide equivalent functionality with current manufacturing support and improved compliance certifications.

Q: Does packaging differ between these parts?

A: The AMT303-V packaging is listed as standard, while both substitutes are packaged in boxes. Packaging differences do not affect electrical or mechanical performance and are determined by supplier logistics requirements.
