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 12-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

Substitute parts for the AMT303-V are identified based on the following critical parameters that determine functional compatibility:

• Encoder Type: Incremental (maintained across all substitutes)
• Output Type: Commutation output (maintained across all substitutes)
• Supply Voltage: 5V (maintained across all substitutes)
• Actuator Type: 2mm–8mm Open Center (maintained across all substitutes)
• Mounting Type: Chassis Mount, Motors (maintained across all substitutes)
• Orientation: Right Angle (maintained across all substitutes)
• Termination Style: Terminal Pins or Connector (compatible alternatives)

The key distinction between the AMT303-V and its substitutes is the pulses per revolution specification. The AMT303-V is fixed at 500 PPR, while the substitute parts (AMT313Q-V and AMT313S-V) feature programmable PPR capability, allowing configuration to match the original 500 PPR requirement or other system specifications. Both substitute parts maintain all other critical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active production parts from CUI Devices and represent direct functional alternatives to the obsolete AMT303-V. The primary selection criterion between these two substitutes is termination style:

• AMT313Q-V: Maintains terminal pin termination, matching the original AMT303-V interface. This part is suitable for direct replacement in existing designs without connector modifications.

• AMT313S-V: Features connector termination instead of terminal pins. This part is suitable for applications where connector-based interfaces are preferred or required by system design.

Both substitutes carry ROHS3 compliance, exceeding the RoHS compliance of the original part. The programmable PPR capability of both substitutes allows configuration to the original 500 PPR specification or adaptation to alternative system requirements. Both parts maintain identical electrical supply voltage, actuator specifications, mounting type, and orientation as the AMT303-V.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 500 PPR specification of the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution capability, allowing configuration to 500 PPR or other specifications as required by the application.

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

A: The termination style differs. AMT313Q-V uses terminal pins (matching the original AMT303-V), while AMT313S-V uses a connector interface. All other electrical and mechanical parameters are identical.

Q: Are the substitute parts compatible with existing AMT303-V mounting locations?

A: Yes. Both AMT313Q-V and AMT313S-V maintain the same mounting type (chassis mount, motors), orientation (right angle), and actuator specifications (2mm–8mm open center) as the AMT303-V.

Q: Do the substitute parts meet current compliance standards?

A: Yes. Both AMT313Q-V and AMT313S-V carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Q: Which substitute part should be selected for direct replacement?

A: AMT313Q-V is recommended for direct replacement applications where terminal pin termination is required. AMT313S-V is suitable where connector-based termination is preferred or specified by system design.
