AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 192 pulses per revolution with commutation output in counter-clockwise (CCW) orientation. This encoder features a right-angle mounting design with a 2mm to 8mm open center actuator and operates at 5V supply voltage. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303-V is determined by the following critical parameters:

• Encoder Type: Must be Incremental
• Supply Voltage: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Output Type: Must support Commutation output

The substitute parts AMT313Q-V and AMT313S-V meet these core mechanical and electrical compatibility criteria. Both are active-status incremental encoders from CUI Devices with identical supply voltage, actuator specifications, mounting configuration, and orientation. The primary distinction between the main part and substitutes is the pulses per revolution specification: the AMT303-V provides fixed 192 PPR output, while the AMT313 series offers programmable PPR capability, allowing configuration to match the original 192 PPR requirement through firmware or hardware programming.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are suitable substitutes for the obsolete AMT303-V based on electrical and mechanical compatibility. The primary selection criterion between the two substitutes is termination style:

• AMT313Q-V: Terminal Pins termination. Select this variant for direct pin-to-pin replacement in existing PCB designs or harness configurations.
• AMT313S-V: Connector termination. Select this variant for applications requiring connector-based integration or where connector-based assembly is preferred.

Both substitute parts carry active product status, ensuring long-term availability and supply chain continuity. Both meet current RoHS3 compliance standards and maintain REACH unaffected status, satisfying modern regulatory requirements. The programmable PPR capability of the AMT313 series provides operational flexibility, allowing configuration to the original 192 PPR specification or alternative pulse rates as system requirements evolve.

Frequently Asked Questions (FAQ)

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

A: Both are electrically and mechanically compatible substitutes. The choice between them depends on termination requirements: AMT313Q-V uses terminal pins, while AMT313S-V uses a connector interface. Select based on your existing integration method.

Q: What is the primary advantage of the AMT313 series over the AMT303-V?

A: The AMT313 series offers programmable pulses per revolution, whereas the AMT303-V provides fixed 192 PPR output. This programmability allows the AMT313 series to be configured to match the original specification or adapted to alternative pulse rate requirements.

Q: Are there any compliance differences between the main part and substitutes?

A: The AMT303-V is RoHS Compliant, while both substitutes are ROHS3 Compliant, representing a more current compliance standard. All three parts maintain REACH unaffected status.

Q: Why is the AMT303-V classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The AMT313Q-V and AMT313S-V are active-status alternatives that provide equivalent functionality with enhanced features and current regulatory compliance.

Q: What supply voltage do all three encoders require?

A: All three parts operate at 5V supply voltage, ensuring direct electrical compatibility in existing 5V systems.

Q: Are the mechanical mounting specifications identical across all three parts?

A: Yes. All three encoders feature identical actuator type (2mm ~ 8mm open center), mounting type (chassis mount, motors), and orientation (right angle), ensuring mechanical interchangeability.
