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 are chassis mount for motor applications
• Orientation: Both are right-angle configurations
• Termination Style: Both use terminal pins
• Output Type: Both provide commutation output
• RoHS Compliance: Both meet RoHS standards
• 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 96 PPR. The AMT313Q-V is currently in active production status, 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 output interface characteristics. The AMT313Q-V maintains active production status and meets current RoHS3 compliance standards, ensuring long-term availability and regulatory alignment. The programmable PPR capability of the AMT313Q-V provides design flexibility beyond the fixed 96 PPR specification of the AMT303LD-V, allowing configuration to match system requirements without component substitution.

Frequently Asked Questions (FAQ)

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

A: Yes. Both components share identical mounting type (chassis mount, right angle), supply voltage (5V), actuator configuration (2mm ~ 8mm open center), and termination style (terminal pins). The AMT313Q-V can be configured to 96 PPR to match the original specification.

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

A: The AMT313Q-V features programmable pulses per revolution, eliminating the need for component substitution if resolution requirements change. The AMT303LD-V is fixed at 96 PPR.

Q: Are there packaging differences between these components?

A: The AMT303LD-V is supplied with terminal pin termination. The AMT313Q-V is packaged in a box configuration. Both use identical terminal pin termination style for circuit integration.

Q: Do both components meet current compliance standards?

A: The AMT303LD-V meets RoHS Compliant standards. The AMT313Q-V meets the more recent ROHS3 Compliant standard, ensuring alignment with current regulatory requirements.

Q: What is the moisture sensitivity rating for both components?

A: Both the AMT303LD-V and AMT313Q-V are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
