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:

• Encoder Type: Both are incremental rotary encoders
• Supply Voltage: Both operate at 5V
• Actuator Type: Both feature 2mm ~ 8mm open center actuators
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both are configured for right-angle mounting
• Termination Style: Both use terminal pin termination
• Output Type: Both provide commutation output
• Compliance: Both are RoHS compliant and REACH unaffected

The primary distinction is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 192 PPR. The AMT313Q-V carries an active product status, making it suitable for applications requiring the same mechanical and electrical interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is suitable as a substitute for the obsolete AMT303LD-V in applications where the following conditions are met:

• The system design can accommodate programmable pulse-per-revolution configuration, with the AMT313Q-V configured to 192 PPR to match the original specification
• The application does not depend on the specific line driver implementation of the AMT303LD-V
• The active product status and ROHS3 compliance of the AMT313Q-V align with current procurement and regulatory requirements

Both parts maintain identical mechanical interfaces, electrical supply requirements, and mounting characteristics, supporting direct functional substitution within the specified parameter constraints.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V shares identical mechanical mounting, orientation, actuator type, and electrical supply voltage with the AMT303LD-V. The primary difference is the programmable PPR capability of the AMT313Q-V. If the system can be configured to operate the AMT313Q-V at 192 PPR, direct functional substitution is supported.

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

A: The AMT313Q-V allows pulse-per-revolution configuration through programming, whereas the AMT303LD-V is fixed at 192 PPR. This provides design flexibility for the AMT313Q-V but requires that the application firmware or hardware supports this configuration capability.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant and REACH unaffected. The AMT303LD-V is RoHS Compliant, while the AMT313Q-V is ROHS3 Compliant, representing an updated compliance standard. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

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

A: The obsolete status indicates that the AMT303LD-V is no longer in active production. The AMT313Q-V, with its active product status and programmable capabilities, represents the current generation alternative from CUI Devices for this encoder category.

Q: What packaging differences exist between these parts?

A: The AMT303LD-V is supplied with standard packaging, while the AMT313Q-V is supplied in box packaging. Both use terminal pin termination for circuit integration.
