Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V qualifies as a substitute for the AMT303LD-V based on the following 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)
• REACH Status: Both are REACH Unaffected
• ECCN Classification: Both classified as EAR99

The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 192 PPR. The AMT313Q-V also carries an active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both components meet identical RoHS and REACH compliance requirements, with the AMT313Q-V meeting the more recent ROHS3 standard. The AMT313Q-V's active product status ensures component availability and manufacturer support for ongoing production and field replacement scenarios.

The programmable pulses per revolution feature of the AMT313Q-V provides design flexibility beyond the fixed 192 PPR specification of the AMT303LD-V. Applications requiring the exact 192 PPR output can configure the AMT313Q-V accordingly, while maintaining all other mechanical and electrical interface compatibility.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mechanical mounting, orientation, actuator type, termination style, and 5V supply voltage. The AMT313Q-V can be configured to output 192 PPR to match the original specification.

Q: What is the primary advantage of substituting with the AMT313Q-V?

A: The AMT313Q-V carries active product status, ensuring long-term availability and manufacturer support. The AMT303LD-V is obsolete and subject to supply discontinuation.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant and REACH Unaffected. The AMT313Q-V meets the ROHS3 standard, which is a more recent revision of the RoHS directive.

Q: Does packaging differ between these encoders?

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

Q: What output specifications should be verified during substitution?

A: Confirm that the AMT313Q-V is programmed to output 192 PPR commutation with CW rotation and 8-pole line driver configuration to match the original AMT303LD-V electrical interface.
