AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 500 pulses per revolution with commutation output, CW polarity, and 2-pole line driver configuration. 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.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303LD-V are identified based on the following critical parameters that determine functional compatibility:

• Encoder Type: Incremental operation
• Supply Voltage: 5V operation
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Termination Style: Terminal Pins
• Output Configuration: Commutation-based output

The AMT313Q-V qualifies as a substitute part because it maintains compatibility across all mandatory mechanical and electrical parameters. The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 500 PPR. This programmability provides additional flexibility while preserving all interface and mounting characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is an active product with current manufacturing status, whereas the AMT303LD-V is obsolete. Both parts maintain RoHS compliance and identical moisture sensitivity ratings. The AMT313Q-V carries ROHS3 certification, representing current regulatory compliance standards.

For applications requiring a fixed 500 PPR configuration, the AMT313Q-V can be programmed to this specification, providing functional equivalence. The programmable nature of the substitute part offers design flexibility without compromising mechanical or electrical interface compatibility.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical mechanical mounting, electrical supply voltage, actuator type, orientation, and termination characteristics. The AMT313Q-V can be configured to match the 500 PPR output of the original part.

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

A: The AMT303LD-V has a fixed 500 PPR output, while the AMT313Q-V features programmable PPR capability. This allows the substitute part to be configured for the original specification or adapted to alternative resolution requirements.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The AMT313Q-V carries ROHS3 certification, which represents the current regulatory standard. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What packaging is available for the AMT313Q-V?

A: The AMT313Q-V is supplied in Box packaging.

Q: Is the AMT313Q-V currently available?

A: Yes. The AMT313Q-V is classified as an active product with 1349 units in stock, compared to the obsolete AMT303LD-V status.
