AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 512 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:

Matching Parameters:

• Manufacturer: CUI Devices (same manufacturer ensures design compatibility)
• Encoder Type: Incremental (same functional classification)
• Voltage - Supply: 5V (identical power requirement)
• Actuator Type: 2mm ~ 8mm Open Center (same mechanical interface)
• Mounting Type: Chassis Mount, Motors (same installation method)
• Orientation: Right Angle (same physical configuration)
• Termination Style: Terminal Pins (same electrical connection method)
• RoHS Status: ROHS3 Compliant (meets or exceeds original compliance)

Differing Parameters:

• Pulses per Revolution: AMT303LD-V is fixed at 512 PPR; AMT313Q-V is programmable
• Output Type: AMT303LD-V specifies Commutation, CW, 2 Pole, with Line Driver; AMT313Q-V specifies Commutation (programmable configuration)
• Product Status: AMT303LD-V is Obsolete; AMT313Q-V is Active

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is a suitable substitute for the obsolete AMT303LD-V based on electrical, mechanical, and regulatory alignment. The primary advantage of the AMT313Q-V is its active product status, ensuring continued availability and supply chain reliability.

The programmable pulses per revolution feature of the AMT313Q-V provides operational flexibility. When configured to 512 PPR, the AMT313Q-V delivers equivalent resolution to the fixed 512 PPR specification of the AMT303LD-V.

Both parts maintain identical compliance certifications (RoHS, REACH, ECCN, HTSUS) and environmental specifications (MSL 1). The AMT313Q-V meets or exceeds the regulatory requirements of the original part.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V without modification?

A: The AMT313Q-V shares all critical mechanical and electrical parameters with the AMT303LD-V, including mounting type, orientation, actuator interface, supply voltage, and termination style. The programmable PPR feature must be configured to 512 to match the original specification. Verification of output signal compatibility with existing control circuitry is required.

Q: What is the significance of the programmable PPR feature in the AMT313Q-V?

A: The AMT313Q-V allows pulses per revolution to be programmed during initialization or operation. For direct substitution of the AMT303LD-V, the AMT313Q-V must be configured to 512 PPR. This programmability also enables the part to serve multiple applications with different resolution requirements.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V packaging is listed as standard; the AMT313Q-V is packaged in a Box. Both use terminal pin termination. Verify packaging requirements for your specific assembly and storage procedures.

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

A: Obsolete status indicates the part is no longer manufactured by CUI Devices. The AMT313Q-V, as an active product from the same manufacturer with equivalent specifications, is the recommended path for new designs and replacement applications.

Q: Are compliance certifications equivalent between the two parts?

A: Both parts carry identical ECCN (EAR99), HTSUS (8543.70.4500), REACH (Unaffected), and MSL (1) classifications. The AMT313Q-V carries ROHS3 Compliant status, which meets or exceeds the RoHS Compliant status of the AMT303LD-V.
