AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 1024 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 compatibility and ensure continued availability for new designs or replacement applications.

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:

• Encoder Type: Both are incremental encoders
• Supply Voltage: Both operate at 5V
• Actuator Type: Both feature 2mm ~ 8mm open center design
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both are right-angle configuration
• Termination Style: Both use terminal pins
• Compliance: Both are RoHS compliant and REACH unaffected
• MSL Rating: Both have MSL 1 (Unlimited)

Key Difference:

• Pulses per Revolution: AMT303LD-V is fixed at 1024 PPR, while AMT313Q-V is programmable
• Output Type: AMT303LD-V specifies commutation with line driver; AMT313Q-V specifies commutation without explicit line driver notation
• Product Status: AMT303LD-V is obsolete; AMT313Q-V is active

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is an active product with current manufacturing status, making it suitable for new designs and ongoing production requirements where the AMT303LD-V is no longer available. Both components meet equivalent compliance standards: RoHS and REACH requirements are satisfied by both parts, with the AMT313Q-V meeting the more recent ROHS3 specification.

The programmable pulses per revolution feature of the AMT313Q-V provides flexibility for applications requiring resolution adjustment, whereas the AMT303LD-V is fixed at 1024 PPR. Applications requiring the exact 1024 PPR specification with line driver output should evaluate whether the AMT313Q-V can be configured to this resolution through programming.

Both parts share identical mechanical and electrical interfaces: 5V supply, right-angle orientation, chassis mount capability, and terminal pin termination. This alignment supports direct substitution in most applications with equivalent mechanical fit and electrical connectivity.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V shares the same mechanical mounting, orientation, supply voltage, and termination style as the AMT303LD-V. The primary consideration is whether the programmable resolution of the AMT313Q-V can be configured to match the fixed 1024 PPR specification of the original part. Electrical interface compatibility depends on the specific output signal requirements of the receiving circuit.

Q: What is the significance of the programmable pulses per revolution feature?

A: The AMT313Q-V allows resolution configuration through programming, whereas the AMT303LD-V is fixed at 1024 PPR. This provides flexibility for applications where resolution adjustment is beneficial, but requires that the receiving system support programmable encoder configuration.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V meets ROHS3 specification, which is a more recent compliance standard than the RoHS Compliant designation of the AMT303LD-V. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the packaging difference?

A: The AMT303LD-V is supplied with standard packaging, while the AMT313Q-V is supplied in box packaging. This difference does not affect component functionality or mechanical compatibility.

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

A: Obsolete status indicates that the manufacturer has discontinued production. The AMT313Q-V, as an active product, represents the current manufacturing alternative from CUI Devices for incremental rotary encoder applications in this category.
