AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 1024 pulses per revolution with commutation output in a right-angle chassis mount configuration. This encoder is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

The AMT303-V operates at 5V supply voltage with an open center actuator design (2mm to 8mm range) and terminal pin termination. Its obsolete status necessitates evaluation of active alternative models that maintain electrical and mechanical compatibility with existing applications.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Must be Incremental
• Voltage Supply: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Termination Style: Terminal Pins or Connector acceptable
• Output Type: Commutation output required
• Pulses per Revolution: 1024 fixed or Programmable to 1024

The substitute parts AMT313Q-V and AMT313S-V meet these core electrical and mechanical requirements. Both feature programmable pulse-per-revolution settings, allowing configuration to match the 1024 PPR specification of the original AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for AMT303-V applications requiring terminal pin termination. Both encoders share identical termination style, mounting configuration, and electrical specifications. The AMT313Q-V maintains active product status with ROHS3 compliance, providing long-term component availability and regulatory alignment. Programmable pulse-per-revolution functionality allows direct configuration to the 1024 PPR requirement of the original design.

AMT313S-V serves as an alternative substitute where connector-based termination is acceptable. This variant offers identical electrical and mechanical compatibility with the exception of termination interface. The connector termination may require interface adapter consideration depending on existing system wiring architecture.

Both substitute parts are manufactured by CUI Devices, ensuring consistency in design philosophy and quality standards. Active product status guarantees continued availability and manufacturing support.

Frequently Asked Questions (FAQ)

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

A: Both parts meet the core electrical and mechanical requirements for substitution. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface. Selection depends on existing system wiring and interface requirements.

Q: What is the significance of programmable pulses per revolution in the substitute parts?

A: The AMT313Q-V and AMT313S-V feature programmable PPR settings, allowing configuration to 1024 PPR to match the fixed specification of the AMT303-V. This flexibility provides additional application versatility beyond the original design requirement.

Q: Are there compliance differences between the original and substitute parts?

A: The AMT303-V carries RoHS Compliant status, while both substitute parts are ROHS3 Compliant. ROHS3 represents an updated compliance standard and does not prevent substitution in existing applications. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.

Q: Why is product status relevant to substitution decisions?

A: The AMT303-V is classified as obsolete, meaning CUI Devices no longer manufactures this model. The substitute parts (AMT313Q-V and AMT313S-V) maintain active product status, ensuring continued availability, manufacturing support, and compliance with current regulatory requirements.

Q: Does the open center actuator design affect substitution compatibility?

A: All three encoders feature identical 2mm to 8mm open center actuator specifications, ensuring mechanical compatibility with existing shaft and coupling interfaces. No mechanical redesign is required for substitution.
