Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V qualifies as a substitute for the AMT303LD-V based on the following alignment of critical parameters:

Matching Parameters:

• Manufacturer: CUI Devices (same manufacturer ensures design consistency)
• Encoder Type: Incremental (same functional classification)
• Output Type: Commutation (same signal output category)
• Voltage - Supply: 5V (identical supply voltage)
• Actuator Type: 2mm ~ 8mm Open Center (identical mechanical interface)
• Mounting Type: Chassis Mount, Motors (same application context)
• Orientation: Right Angle (identical physical orientation)
• Termination Style: Terminal Pins (same connection method)
• RoHS Status: ROHS3 Compliant (meets or exceeds environmental compliance)

Key Difference:

• Pulses per Revolution: AMT303LD-V is fixed at 200 PPR; AMT313Q-V is programmable

The programmable PPR capability of the AMT313Q-V provides functional flexibility while maintaining compatibility across all mechanical, electrical, and environmental parameters.

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Selection is based on the following engineering criteria:

Product Status: The AMT313Q-V maintains active product status with current manufacturing support, whereas the AMT303LD-V is obsolete and subject to discontinuation.

Compliance Alignment: Both parts meet RoHS requirements. The AMT313Q-V achieves ROHS3 compliance, representing current environmental standards.

Functional Compatibility: All mechanical, electrical, and interface parameters align between the two parts. The programmable PPR feature of the AMT313Q-V does not compromise compatibility with fixed 200 PPR applications; the part can be configured to operate at 200 PPR when required.

Supply Chain Continuity: The AMT313Q-V has documented inventory availability (1349 units), ensuring procurement reliability for new designs and replacement applications.

Frequently Asked Questions (FAQ)

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

A: Yes. The AMT313Q-V maintains identical mechanical mounting, electrical supply voltage, actuator interface, and termination style. The programmable PPR capability does not prevent operation at the fixed 200 PPR specification of the original part.

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

A: The AMT313Q-V allows PPR configuration during system setup or operation, providing design flexibility. For applications requiring fixed 200 PPR operation, the part can be programmed to this specification.

Q: Are there differences in output signal characteristics between these parts?

A: Both parts provide commutation output with line driver configuration. The AMT313Q-V output type is listed as commutation, which is compatible with the commutation, CW, 2-pole line driver specification of the AMT303LD-V.

Q: What packaging differences exist between these parts?

A: The AMT303LD-V uses standard packaging, while the AMT313Q-V is supplied in box packaging. Both use terminal pin termination, ensuring compatibility with existing connector and PCB interfaces.

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

A: Obsolescence reflects the manufacturer's discontinuation of this model line. The AMT313Q-V represents the current active product offering from CUI Devices in this encoder category.

Q: Are there compliance or certification differences?

A: Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V achieves ROHS3 compliance, representing alignment with current environmental regulations.
