Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V qualifies as a substitute based on the following alignment of critical 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 configurations
• Termination Style: Both use terminal pins
• Compliance: Both are RoHS compliant and REACH unaffected
• Output Type: Both provide commutation output

The primary distinction is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 800 PPR. The AMT313Q-V's programmable capability allows configuration to match the 800 PPR specification of the original part.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the identified substitute for the obsolete AMT303LD-V. Selection of the AMT313Q-V is supported by:

• Product Status: The AMT313Q-V maintains active product status, ensuring ongoing availability and manufacturing support
• Compliance Alignment: Both parts meet RoHS and REACH requirements, with the AMT313Q-V meeting the more recent ROHS3 standard
• Functional Equivalence: Matching encoder type, supply voltage, mechanical form factor, and output characteristics enable direct substitution
• Programmable Configuration: The AMT313Q-V's programmable PPR capability allows configuration to the 800 PPR specification of the original part, eliminating any functional gap

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V shares identical mechanical mounting, electrical supply voltage, and output type characteristics. The programmable PPR feature must be configured to 800 PPR to match the original specification. No hardware modification is required.

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

A: The AMT313Q-V allows PPR configuration through programming, whereas the AMT303LD-V is fixed at 800 PPR. This flexibility enables the AMT313Q-V to match the original 800 PPR setting and adapt to other system requirements if needed.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V uses terminal pin termination in standard packaging. The AMT313Q-V is supplied in box packaging. Both use identical termination style and are compatible with the same connector and mounting interfaces.

Q: How do the RoHS compliance levels differ?

A: The AMT303LD-V meets RoHS Compliant status. The AMT313Q-V meets ROHS3 Compliant status, which represents a more recent and stringent compliance standard. This upgrade in compliance does not affect functional compatibility.

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

A: Product obsolescence typically results from manufacturer discontinuation decisions. The AMT313Q-V represents the active alternative within the CUI Devices encoder product line, offering equivalent functionality with enhanced programmability.
