AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 200 pulses per revolution with commutation output, CCW rotation, 4-pole configuration, and integrated line driver. The unit operates at 5V supply voltage with a right-angle orientation and chassis mount capability for motor applications.

This part carries an Obsolete product status. Identifying equivalent substitute components is necessary to maintain system functionality and ensure continued availability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V qualifies as a substitute for the AMT303LD-V based on the following alignment of critical parameters:

Matching Parameters:

• Encoder Type: Both are Incremental encoders
• Supply Voltage: Both operate at 5V
• Actuator Type: Both feature 2mm ~ 8mm Open Center configuration
• Mounting Type: Both support Chassis Mount, Motors installation
• Orientation: Both are Right Angle configuration
• Termination Style: Both use Terminal Pins
• Compliance: Both are RoHS Compliant and REACH Unaffected
• ECCN/HTSUS Classification: Identical regulatory codes

Key Difference:

• Pulses per Revolution: AMT303LD-V is fixed at 200 PPR; AMT313Q-V is Programmable
• Output Type: AMT303LD-V includes 4-pole line driver; AMT313Q-V provides standard commutation output
• Product Status: AMT313Q-V is Active (current production)

The substitution is valid where the programmable PPR capability and alternative output configuration are compatible with system requirements.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is available as an active production component from CUI Devices, addressing the obsolescence of the AMT303LD-V. Both parts maintain identical RoHS and REACH compliance status, with the substitute meeting ROHS3 specifications.

Selection of the AMT313Q-V requires confirmation that the programmable pulses-per-revolution capability and commutation output (without integrated 4-pole line driver) are functionally compatible with the target application. The mechanical and electrical interface parameters—supply voltage, actuator geometry, mounting configuration, and termination style—are equivalent between both parts.

Frequently Asked Questions (FAQ)

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

A: Mechanical and electrical interfaces are compatible. The primary consideration is whether the programmable PPR feature and alternative output configuration meet application requirements. The AMT303LD-V's integrated 4-pole line driver is not present in the AMT313Q-V.

Q: Are the supply voltage and mounting specifications identical?

A: Yes. Both parts operate at 5V, feature right-angle orientation, support chassis mount installation, and use identical actuator geometry (2mm ~ 8mm open center) and terminal pin termination.

Q: What is the difference in output type between these encoders?

A: The AMT303LD-V provides commutation output with CCW rotation, 4-pole configuration, and integrated line driver. The AMT313Q-V provides standard commutation output without the line driver stage.

Q: Are both parts RoHS compliant?

A: Yes. The AMT303LD-V is RoHS Compliant; the AMT313Q-V is ROHS3 Compliant. Both are REACH Unaffected and share identical ECCN and HTSUS classifications.

Q: Why is the AMT303LD-V listed as Obsolete?

A: The AMT303LD-V has reached end-of-life status. The AMT313Q-V represents the active production alternative from CUI Devices for similar applications requiring incremental encoder functionality.
