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
• Voltage Supply: 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
• RoHS Compliance: Both meet RoHS standards
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)

Key Difference:

• Pulses per Revolution: AMT303LD-V is fixed at 512 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• Product Status: AMT303LD-V is obsolete; AMT313Q-V is active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 long-term availability. Both parts maintain equivalent RoHS compliance standards, with the AMT313Q-V meeting the more recent ROHS3 specification.

The programmable pulses per revolution feature of the AMT313Q-V provides design flexibility compared to the fixed 512 PPR configuration of the AMT303LD-V. This characteristic allows system configuration without component substitution if resolution requirements change.

Both encoders share identical supply voltage, mechanical mounting, and termination characteristics, supporting direct functional replacement in applications where the output type specifications align with system requirements.

Frequently Asked Questions (FAQ)

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

A: Functional replacement is possible when the following conditions are met: the system operates at 5V supply, uses right-angle chassis mount configuration with terminal pin termination, and the output type requirements are compatible. The programmable PPR feature of the AMT313Q-V can be configured to match the 512 PPR specification of the AMT303LD-V.

Q: What is the significance of the programmable pulses per revolution in the AMT313Q-V?

A: The programmable PPR feature allows the encoder resolution to be configured during system setup or operation, eliminating the need for component substitution if resolution requirements change. The AMT303LD-V provides a fixed 512 PPR configuration.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is specified with dash packaging, while the AMT313Q-V is supplied in box packaging. Both use identical terminal pin termination and mounting interfaces.

Q: How do the RoHS compliance levels differ?

A: The AMT303LD-V meets RoHS Compliant standards, while the AMT313Q-V meets the more recent ROHS3 Compliant specification. Both parts are REACH Unaffected and classified under ECCN EAR99.

Q: What is the inventory status for these parts?

A: The AMT303LD-V has 680 pieces available as new original stock. The AMT313Q-V has 1349 pieces available as new original stock, reflecting its active product status.
