AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, designed for chassis mount and motor applications with right-angle orientation. This encoder provides 1000 pulses per revolution output with commutation, CW, 2-pole configuration and integrated line driver functionality. The product is classified as obsolete, making identification of suitable substitute components necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303LD-V is determined by alignment across the following critical parameters:

• Encoder Type: Must be Incremental
• Supply Voltage: Must be 5V
• Mounting Configuration: Must support Chassis Mount, Motors with Right Angle orientation
• Actuator Type: Must accommodate 2mm ~ 8mm Open Center range
• Termination Style: Must use Terminal Pins
• Output Compatibility: Must provide commutation output with line driver capability
• Regulatory Compliance: Must maintain RoHS and REACH compliance status

The AMT313Q-V meets these substitution criteria with the exception of pulses per revolution, which is programmable rather than fixed at 1000 PPR. This flexibility in PPR configuration allows the AMT313Q-V to serve applications requiring the AMT303LD-V's core functional parameters while offering extended configurability.

Parameter Comparison

Engineering Selection Recommendations

The AMT303LD-V is classified as obsolete, necessitating component replacement for new procurements and system continuations. The AMT313Q-V is the identified substitute, currently in active production status with 1349 units available in inventory.

Selection of the AMT313Q-V as a replacement is supported by:

• Identical 5V supply voltage requirement
• Matching mechanical configuration: right-angle orientation, chassis mount capability, 2mm ~ 8mm open center actuator compatibility
• Identical termination methodology: terminal pins
• Enhanced regulatory compliance: ROHS3 Compliant (versus RoHS Compliant on the original part)
• Maintained REACH Unaffected status
• Active product status ensuring long-term availability and supply chain stability

The primary functional difference is the programmable pulses per revolution on the AMT313Q-V, which can be configured to 1000 PPR to match the original AMT303LD-V specification when required by system design parameters.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V in existing applications?

A: The AMT313Q-V shares identical mechanical mounting, electrical supply voltage, and termination characteristics with the AMT303LD-V. The programmable PPR feature of the AMT313Q-V can be configured to 1000 PPR to match the original specification. Compatibility depends on whether the application's control electronics support programmable encoder configuration.

Q: What is the difference between fixed 1000 PPR and programmable PPR?

A: The AMT303LD-V provides a fixed output of 1000 pulses per revolution. The AMT313Q-V allows PPR configuration through programming, providing flexibility for multiple application requirements while maintaining the same physical form factor and electrical interface.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is specified with "-" packaging notation, while the AMT313Q-V is supplied in Box packaging. Both use identical terminal pin termination and mounting configurations.

Q: Does the regulatory compliance differ between these encoders?

A: Both parts maintain REACH Unaffected status. The AMT313Q-V carries ROHS3 Compliant certification, representing an updated compliance standard compared to the RoHS Compliant designation on the AMT303LD-V.

Q: What is the current availability status of these parts?

A: The AMT303LD-V is obsolete with 737 units in current inventory. The AMT313Q-V is in active production with 1349 units available, providing superior long-term supply chain assurance.
