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 line driver capability. 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 functionality and ensure continued availability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Must be Incremental
• Supply Voltage: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Termination Style: Must be Terminal Pins
• Detent: Must be No
• Built in Switch: Must be No

The AMT313Q-V qualifies as a substitute because it matches all critical mechanical and electrical parameters. The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 400 PPR. This difference does not prevent substitution when the application can accommodate programmable resolution or when 400 PPR operation is selected within the programmable range.

Engineering Selection Recommendations

The AMT313Q-V is the qualified substitute for the obsolete AMT303LD-V. Selection should be based on the following factors:

Product Status: The AMT303LD-V is obsolete, while the AMT313Q-V is active. The active status of the AMT313Q-V ensures continued availability and manufacturing support.

Compliance: Both parts maintain equivalent environmental compliance. The AMT313Q-V achieves ROHS3 Compliant status, which represents a higher compliance standard than the RoHS Compliant designation of the AMT303LD-V. Both parts are REACH Unaffected and carry identical moisture sensitivity ratings.

Functional Compatibility: The AMT313Q-V maintains all critical mechanical and electrical parameters required for direct substitution. The programmable pulses per revolution feature of the AMT313Q-V provides operational flexibility while supporting fixed 400 PPR operation when required.

Frequently Asked Questions (FAQ)

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

A: Yes. The AMT313Q-V matches all critical parameters: 5V supply voltage, incremental encoder type, commutation output, right-angle orientation, chassis mount configuration, terminal pin termination, and identical actuator specifications. No mechanical or electrical modifications are required.

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

A: The AMT303LD-V provides fixed 400 pulses per revolution, while the AMT313Q-V offers programmable resolution. Both can operate at 400 PPR when configured accordingly.

Q: Are there compliance or certification differences?

A: Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V carries ROHS3 Compliant certification, representing current compliance standards. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Does packaging differ between these parts?

A: The AMT303LD-V uses standard packaging, while the AMT313Q-V is supplied in box packaging. This difference does not affect functional compatibility or performance.

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

A: Obsolescence typically reflects manufacturer discontinuation decisions. The active status of the AMT313Q-V provides a direct path for continued system support and new designs.
