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:

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

The primary distinction is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 200 PPR. The AMT313Q-V is an active product, addressing the obsolescence of the AMT303LD-V.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both components share identical mechanical mounting, electrical supply requirements, and compliance certifications. The AMT313Q-V maintains active product status with ROHS3 compliance, ensuring continued availability and regulatory alignment. The programmable pulses per revolution feature of the AMT313Q-V provides design flexibility while maintaining compatibility with the fixed 200 PPR specification of the original part when configured accordingly.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical supply voltage (5V), actuator type (2mm ~ 8mm open center), mounting configuration (chassis mount, right angle), and termination style (terminal pins). The AMT313Q-V's programmable PPR can be configured to match the AMT303LD-V's 200 PPR specification.

Q: What is the primary advantage of the AMT313Q-V over the AMT303LD-V?

A: The AMT313Q-V is an active product with current manufacturing support, whereas the AMT303LD-V is obsolete. Additionally, the programmable pulses per revolution feature allows configuration flexibility for various application requirements.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V uses standard packaging, while the AMT313Q-V is supplied in box packaging. Both use terminal pin termination suitable for chassis mount applications.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both are RoHS compliant and REACH unaffected. The AMT313Q-V carries ROHS3 compliance, representing the current regulatory standard.

Q: Are there any electrical compatibility concerns when substituting the AMT313Q-V for the AMT303LD-V?

A: No. Both operate at 5V supply voltage with identical moisture sensitivity ratings (MSL 1, Unlimited) and output commutation characteristics. Electrical interface compatibility is maintained.
