AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 512 pulses per revolution (PPR) output. This encoder features a right-angle orientation, chassis mount configuration, and 5V supply voltage operation. 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 of the AMT303-V is based on alignment of the following critical parameters:

• Encoder Type: Incremental
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Output Type: Commutation
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: RoHS3 or equivalent

The substitute parts AMT313Q-V and AMT313S-V maintain compatibility across these core parameters. Both alternatives feature programmable pulses per revolution, allowing configuration to match the 512 PPR specification of the original AMT303-V. The primary distinction between substitutes is termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing long-term availability compared to the obsolete AMT303-V. Both alternatives maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

For applications requiring direct pin-compatible replacement with minimal circuit board modification, the AMT313Q-V is the preferred substitute due to identical terminal pin termination. The programmable PPR capability of the AMT313Q-V allows configuration to the 512 PPR specification required by the original design.

For applications where connector-based termination is acceptable or preferred, the AMT313S-V provides equivalent functional performance with the added benefit of connector-based interface, potentially simplifying field replacement and maintenance procedures.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303-V without circuit board modifications?

A: The AMT313Q-V maintains identical termination style (terminal pins), mounting type, orientation, and electrical specifications. Direct substitution is possible provided the application can accommodate the programmable PPR configuration to 512 PPR.

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

A: The AMT313Q-V uses terminal pin termination, matching the original AMT303-V configuration. The AMT313S-V uses a connector-based termination interface. Both maintain identical electrical and mechanical specifications otherwise.

Q: Are the substitute parts compatible with 5V supply voltage systems?

A: Both AMT313Q-V and AMT313S-V operate at 5V supply voltage, matching the original AMT303-V specification.

Q: Do the substitute encoders support the same 512 PPR output as the original?

A: The substitute parts feature programmable pulses per revolution. Configuration to 512 PPR is supported through programming, matching the fixed 512 PPR specification of the AMT303-V.

Q: What is the packaging format for the substitute parts?

A: AMT313Q-V is supplied in box packaging. AMT313S-V is supplied in box packaging.

Q: Are the substitute parts RoHS compliant?

A: Both AMT313Q-V and AMT313S-V are ROHS3 compliant, meeting current environmental and regulatory standards.
