AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 200 pulses per revolution with commutation output in counter-clockwise (CCW) orientation. This encoder features a right-angle mounting configuration with a 2mm to 8mm open center actuator and operates at 5V supply voltage. The product is classified as obsolete, necessitating identification of active alternative models that maintain functional and mechanical compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Incremental operation
• Supply Voltage: 5V operation
• Actuator Type: 2mm to 8mm open center configuration
• Mounting Type: Chassis mount and motor mounting compatibility
• Orientation: Right angle mechanical orientation
• Output Characteristics: Commutation output capability

The identified substitute parts (AMT313Q-V and AMT313S-V) maintain these core functional and mechanical parameters. The primary distinction between the main part and substitutes is the pulses per revolution specification: the AMT303-V operates at a fixed 200 PPR, while the substitute models feature programmable PPR capability, allowing configuration to 200 PPR or other values as required by the application.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing long-term availability and supply chain stability compared to the obsolete AMT303-V. Both substitute models maintain full compliance with ROHS3 standards and REACH regulations, meeting current environmental and regulatory requirements.

The selection between AMT313Q-V and AMT313S-V depends on termination requirements: the AMT313Q-V retains terminal pin termination matching the original AMT303-V configuration, while the AMT313S-V employs connector-based termination. For applications requiring minimal redesign of existing interconnect schemes, the AMT313Q-V provides direct compatibility. The programmable PPR capability of both substitutes offers design flexibility, allowing configuration to the original 200 PPR specification or alternative values as application requirements evolve.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to operate at 200 PPR like the original AMT303-V?

A: Yes. Both substitute models feature programmable pulses per revolution capability, allowing configuration to 200 PPR or other values as required. Configuration parameters must be set according to the manufacturer's programming specifications.

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

A: The termination style differs between the two models. The AMT313Q-V uses terminal pins for connection, while the AMT313S-V employs a connector interface. Both maintain identical electrical and mechanical specifications for encoder operation, supply voltage, actuator type, and mounting configuration.

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

A: Yes. Both AMT313Q-V and AMT313S-V maintain the same right-angle orientation, chassis mount and motor mounting compatibility, and 2mm to 8mm open center actuator specification as the original AMT303-V.

Q: Do the substitute models meet current regulatory compliance standards?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original AMT303-V is RoHS compliant but does not carry the updated ROHS3 designation.

Q: What supply voltage do the substitute encoders require?

A: Both substitute models operate at 5V supply voltage, identical to the original AMT303-V specification.
