AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 800 pulses per revolution with commutation output in a right-angle chassis mount configuration. This encoder is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The part operates at 5V supply voltage with an open center actuator design and terminal pin termination.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are selected based on strict parameter alignment in the following categories:

Electrical Compatibility:

• Incremental encoder type (matching functional output principle)
• 5V supply voltage (identical power requirement)
• Commutation output type (matching signal format)

Mechanical Compatibility:

• Right angle orientation (identical form factor)
• 2mm ~ 8mm open center actuator (identical mechanical interface)
• Chassis mount configuration (identical mounting method)
• Terminal pin or connector termination (compatible connection methods)

Regulatory Compliance:

• RoHS compliance status (environmental standards)
• REACH unaffected classification (chemical regulations)

The substitute parts AMT313Q-V and AMT313S-V maintain these core parameters while offering programmable pulses per revolution capability, providing design flexibility for applications requiring variable resolution.

Engineering Selection Recommendations

AMT313Q-V Selection Criteria:

• Active product status with current manufacturing support
• ROHS3 compliance (enhanced environmental standard)
• Terminal pin termination matching the original AMT303-V interface
• Programmable pulses per revolution allows configuration to 800 PPR or alternative resolutions as required
• Suitable for direct replacement in existing designs with terminal pin connections

AMT313S-V Selection Criteria:

• Active product status with current manufacturing support
• ROHS3 compliance (enhanced environmental standard)
• Connector termination provides alternative connection method
• Programmable pulses per revolution allows configuration to 800 PPR or alternative resolutions as required
• Suitable for new designs or retrofits where connector-based termination is preferred

Both substitute parts maintain full electrical and mechanical compatibility with the obsolete AMT303-V while offering the advantage of programmable resolution and active product lifecycle status.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 800 PPR specification of the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution, allowing configuration to 800 PPR to match the original specification.

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

A: The termination style differs. AMT313Q-V uses terminal pins, while AMT313S-V uses a connector interface. Both maintain identical electrical and mechanical parameters.

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

A: Yes. Both AMT313Q-V and AMT313S-V maintain identical mounting type (chassis mount), orientation (right angle), and actuator specifications (2mm ~ 8mm open center).

Q: What is the significance of the product status change from obsolete to active?

A: Active product status ensures continued manufacturing support, availability, and technical documentation. Obsolete products may face supply constraints and limited manufacturer support.

Q: Do the substitute parts meet the same regulatory requirements as the AMT303-V?

A: Yes. Both substitute parts maintain REACH unaffected status and RoHS compliance (ROHS3 standard, which is an enhanced version of the original RoHS compliance).

Q: Can the AMT313Q-V be used as a direct pin-for-pin replacement?

A: Yes, for applications using terminal pin termination. The AMT313Q-V maintains identical termination style and electrical interface as the AMT303-V.

Q: Which substitute part should be selected for new designs?

A: Selection depends on termination preference. Choose AMT313Q-V for terminal pin applications or AMT313S-V for connector-based applications. Both are active products with full manufacturer support.
