AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 400 pulses per revolution with commutation output, CCW rotation, 6-pole configuration, and line driver capability in a right-angle orientation. This component is classified as obsolete, necessitating identification of active substitute parts for new designs and ongoing production requirements. The encoder is designed for chassis mount and motor applications with 5V supply voltage and terminal pin termination.

Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V is identified as a substitute for the AMT303LD-V based on the following alignment of critical 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 and motor applications
• Orientation: Both are right-angle designs
• Termination Style: Both use terminal pins
• Output Configuration: Both provide commutation output
• Compliance: Both are RoHS compliant and REACH unaffected
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The primary distinction is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 400 PPR. The AMT313Q-V is currently in active production status, making it suitable for applications requiring the AMT303LD-V functionality.

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Selection of the AMT313Q-V is supported by:

• Product Status Alignment: The AMT313Q-V maintains active production status, ensuring long-term availability and supply chain continuity
• Compliance Enhancement: The AMT313Q-V meets ROHS3 compliance, representing an updated regulatory standard compared to the RoHS Compliant designation of the main part
• Functional Compatibility: Both parts maintain identical electrical specifications (5V supply), mechanical interfaces (right-angle orientation, chassis mount, terminal pins), and environmental ratings (MSL 1)
• Programmable Resolution: The AMT313Q-V offers programmable pulses per revolution capability, providing design flexibility for applications previously constrained to the fixed 400 PPR specification of the AMT303LD-V

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V across all shared parameters: 5V supply voltage, right-angle orientation, chassis mount configuration, terminal pin termination, and commutation output type. The programmable PPR feature of the AMT313Q-V can be configured to match the fixed 400 PPR specification of the AMT303LD-V.

Q: What is the primary difference between these two encoders?

A: The AMT303LD-V provides a fixed 400 pulses per revolution output, while the AMT313Q-V features programmable pulses per revolution. Both encoders share identical mechanical mounting, electrical supply requirements, and environmental ratings.

Q: Are there packaging differences between the main part and substitute?

A: The AMT303LD-V is supplied with terminal pin termination, while the AMT313Q-V is packaged in a box configuration. Both use identical terminal pin termination style for circuit integration.

Q: Does the AMT313Q-V meet current regulatory requirements?

A: Yes. The AMT313Q-V is ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The main part (AMT303LD-V) is RoHS compliant and also REACH unaffected.

Q: What is the inventory status of these parts?

A: The AMT303LD-V has 731 pieces in stock as new original inventory. The AMT313Q-V has 1,349 pieces in stock as new original inventory and is in active production.
