AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 192 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 design continuity and ensure component availability for new production runs, repairs, and system upgrades.

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 part because it matches all mandatory parameters. While the AMT313Q-V features programmable pulses per revolution (versus the fixed 192 PPR of the AMT303LD-V), this represents a functional enhancement rather than a limitation, as programmable resolution can be configured to match the original 192 PPR specification.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the qualified substitute for the obsolete AMT303LD-V based on the following criteria:

Product Status: The AMT313Q-V maintains active product status with CUI Devices, ensuring ongoing availability and supply chain continuity. The AMT303LD-V is obsolete, making the AMT313Q-V the appropriate long-term replacement.

Regulatory Compliance: Both parts maintain equivalent environmental and regulatory certifications. The AMT313Q-V achieves ROHS3 Compliant status (an enhanced RoHS standard) compared to the AMT303LD-V's RoHS Compliant designation. Both parts are REACH Unaffected and carry MSL 1 (Unlimited) ratings, indicating identical moisture handling requirements.

Functional Compatibility: The AMT313Q-V's programmable pulses per revolution feature provides design flexibility while maintaining backward compatibility with the fixed 192 PPR configuration of the original part. All mechanical, electrical, and interface parameters remain consistent.

Frequently Asked Questions (FAQ)

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

A: Yes. The AMT313Q-V matches all mandatory mechanical and electrical parameters: 5V supply voltage, right-angle orientation, chassis mount configuration, terminal pin termination, and identical actuator specifications. No PCB modifications are required.

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

A: The AMT303LD-V provides a fixed 192 pulses per revolution output, while the AMT313Q-V offers programmable resolution. The AMT313Q-V can be configured to operate at 192 PPR to match the original specification.

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

A: The AMT303LD-V uses terminal pin packaging, while the AMT313Q-V is supplied in box packaging. Both employ identical terminal pin termination for circuit board integration.

Q: Does the AMT313Q-V require firmware or software configuration?

A: The provided parameters indicate the AMT313Q-V features programmable resolution capability. Configuration requirements depend on the specific application interface and control system implementation.

Q: Are compliance certifications equivalent?

A: Both parts maintain REACH Unaffected and MSL 1 (Unlimited) status. The AMT313Q-V achieves ROHS3 Compliant certification, which represents an enhanced compliance standard relative to the AMT303LD-V's RoHS Compliant designation.

Q: Why is the AMT303LD-V obsolete?

A: Product obsolescence is determined by the manufacturer. The AMT313Q-V's programmable architecture and active product status make it the recommended replacement for new designs and production continuity.
