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 and integrated line driver functionality. This component is designed for chassis mount and motor applications with right-angle orientation and terminal pin termination.

The AMT303LD-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for new designs or replacement applications where the original part is no longer in production.

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 actuators
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both are right-angle configurations
• Termination Style: Both use terminal pins
• Compliance: Both are RoHS compliant and REACH unaffected
• MSL Rating: Both have MSL 1 (Unlimited)

The primary difference 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.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is suitable as a substitute for the AMT303LD-V in applications requiring incremental rotary encoding with the specified mechanical and electrical parameters. The substitute part maintains compatibility across all critical dimensions: supply voltage, actuator range, mounting configuration, and termination method.

The AMT313Q-V carries active product status and meets current RoHS3 compliance requirements, providing assurance of continued availability and regulatory alignment. The programmable pulses per revolution feature of the AMT313Q-V offers design flexibility, allowing configuration to 400 PPR to match the original part's fixed specification if required by system firmware or hardware configuration.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V shares all critical mechanical and electrical parameters with the AMT303LD-V, including supply voltage, actuator type, mounting configuration, and termination style. Substitution is feasible provided the system can accommodate the programmable PPR feature of the substitute part.

Q: What is the primary functional difference between these two parts?

A: The AMT303LD-V has a fixed 400 PPR specification, while the AMT313Q-V features programmable pulses per revolution. Both are incremental encoders with commutation output and 5V supply requirements.

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

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

Q: Does the substitute part meet current compliance standards?

A: Yes. The AMT313Q-V is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original AMT303LD-V is RoHS compliant and also REACH unaffected.

Q: What is the inventory status of these parts?

A: The AMT303LD-V (obsolete) has 721 pieces in stock. The AMT313Q-V (active) has 1349 pieces in stock, providing greater availability for new orders and future requirements.
