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 right-angle orientation. This encoder is designed for chassis mount and motor applications with a 5V supply voltage 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 applications requiring this encoder specification.

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 (required match)
• Voltage Supply: 5V (required match)
• Actuator Type: 2mm–8mm Open Center (required match)
• Mounting Type: Chassis Mount, Motors (required match)
• Orientation: Right Angle (required match)
• Output Type: Commutation (required match)
• Manufacturer: CUI Devices (same manufacturer ecosystem)

The substitute parts AMT313Q-V and AMT313S-V meet these core compatibility criteria. Both are active products from CUI Devices with identical mechanical and electrical interfaces. The primary difference is the pulses per revolution specification: while the AMT303-V is fixed at 500 PPR, the substitute parts feature programmable PPR, allowing configuration to match the original 500 PPR requirement.

Parameter Comparison

Engineering Selection Recommendations

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

• AMT313Q-V: Terminal Pins termination (matches AMT303-V termination style)
• AMT313S-V: Connector termination (alternative interface)

For applications requiring minimal redesign, the AMT313Q-V is the preferred substitute due to identical termination methodology. Both substitutes feature programmable pulses per revolution, which must be configured to 500 PPR to match the original AMT303-V specification.

Both substitute parts meet current RoHS3 compliance and REACH requirements, providing improved regulatory alignment compared to the obsolete original part.

Frequently Asked Questions (FAQ)

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

A: Both parts are functionally compatible with AMT303-V when the programmable PPR is set to 500. The key difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface. Selection depends on your application's wiring requirements.

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

A: The AMT313Q-V and AMT313S-V feature programmable pulses per revolution, allowing configuration flexibility. For AMT303-V replacement, these parts must be programmed to 500 PPR to maintain identical encoder resolution.

Q: Are there packaging differences between the substitute parts?

A: AMT313Q-V is supplied in Box packaging, as is AMT313S-V. Both are available in active production with higher inventory levels than the obsolete AMT303-V.

Q: Do the substitute parts meet the same compliance standards?

A: Both AMT313Q-V and AMT313S-V meet ROHS3 compliance and REACH requirements. The original AMT303-V was RoHS Compliant. The substitutes provide enhanced regulatory alignment with current standards.

Q: What mounting and orientation specifications apply to all three parts?

A: All three encoders share identical mounting (Chassis Mount, Motors), orientation (Right Angle), actuator type (2mm–8mm Open Center), and supply voltage (5V), ensuring mechanical and electrical compatibility in existing applications.
