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 4-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 system compatibility and ensure continued availability for new designs or replacement applications where the original part is no longer in production.

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
• Supply Voltage: Must be 5V
• Actuator Type: Must be 2mm – 8mm Open Center
• Mounting Type: Must support Chassis Mount and Motors applications
• Orientation: Must be Right Angle
• Pulses per Revolution: The AMT303-V specifies 500 PPR; substitute parts with programmable PPR capability can be configured to match this specification

The substitute parts AMT313Q-V and AMT313S-V meet these core electrical and mechanical compatibility criteria. Both are active products from CUI Devices with programmable pulse-per-revolution settings, allowing configuration to the 500 PPR requirement of the original design.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing supply chain continuity for applications previously using the obsolete AMT303-V.

AMT313Q-V maintains terminal pin termination, matching the original AMT303-V connection style. This part is suitable for direct integration into existing PCB designs without connector modifications.

AMT313S-V uses connector termination instead of terminal pins. Selection of this variant requires mechanical and electrical interface adaptation but offers standardized connector-based connectivity for modular applications.

Both substitute parts comply with ROHS3 and REACH requirements, meeting current regulatory standards. The programmable PPR capability of both substitutes allows configuration to the 500 PPR specification of the original design, ensuring functional equivalence in pulse output.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be directly substituted for AMT303-V?

A: Both parts meet the core electrical and mechanical compatibility requirements: incremental encoder type, commutation output, 5V supply, 2mm–8mm open center actuator, right angle orientation, and chassis mount capability. The programmable PPR feature allows both to be configured to 500 PPR. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface.

Q: What is the difference between AMT313Q-V and AMT313S-V?

A: Both parts are functionally equivalent in encoder operation and electrical specifications. The distinction is termination style: AMT313Q-V provides terminal pins for direct soldering or pin insertion, while AMT313S-V uses a connector interface. Selection depends on the application's mechanical and electrical interface requirements.

Q: Why is the AMT303-V obsolete?

A: The AMT303-V is classified as obsolete by the manufacturer. The AMT313 series (AMT313Q-V and AMT313S-V) represent the current active product line from CUI Devices for this encoder category, offering programmable configuration flexibility and continued manufacturing support.

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

A: The AMT303-V is RoHS Compliant. Both substitute parts are ROHS3 Compliant, representing a higher standard of environmental compliance. All three parts are REACH Unaffected and carry the same moisture sensitivity level (MSL 1 – Unlimited), ensuring equivalent reliability in storage and handling.

Q: Can the programmable PPR feature of AMT313Q-V and AMT313S-V be set to 500 PPR?

A: Yes. Both substitute parts feature programmable PPR capability, which can be configured to match the 500 PPR specification of the AMT303-V, ensuring functional equivalence in pulse output for the application.
