Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on the following critical parameters that determine functional compatibility:

• Encoder Type: Incremental (maintained across all substitutes)
• Output Type: Commutation output capability
• Voltage Supply: 5V operation
• Actuator Type: 2mm ~ 8mm open center shaft
• Mounting Type: Chassis mount and motor applications
• Orientation: Right angle configuration
• Mechanical Interface: Compatible with existing mounting and termination requirements

The AMT313Q-V and AMT313S-V are qualified substitutes because they maintain the core electrical and mechanical parameters required for system integration. Both parts operate at 5V, support commutation output, feature identical actuator and mounting specifications, and are available in active product status. The primary distinction between substitutes relates to termination style and programmable pulse-per-revolution capability.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active-status alternatives to the obsolete AMT303-V, providing continued access to compatible incremental encoder technology. Selection between substitutes depends on termination requirements:

AMT313Q-V maintains terminal pin termination identical to the original AMT303-V, supporting direct integration into existing harness and PCB designs without connector modification.

AMT313S-V provides connector-based termination, requiring interface adaptation but offering standardized connector compatibility for modular system designs.

Both substitutes feature programmable pulse-per-revolution capability, allowing configuration to 1024 PPR or alternative resolutions as required by system specifications. Both maintain ROHS3 compliance and unlimited moisture sensitivity rating, meeting current regulatory and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V directly replace AMT303-V in existing applications?

A: Both parts maintain electrical and mechanical compatibility with the AMT303-V. AMT313Q-V provides identical terminal pin termination for direct substitution. AMT313S-V requires connector interface adaptation.

Q: What is the primary difference between AMT313Q-V and AMT313S-V?

A: Termination style differs. AMT313Q-V uses terminal pins; AMT313S-V uses a connector interface. Both maintain identical electrical specifications and mounting characteristics.

Q: Are the substitute parts programmable to 1024 PPR?

A: Yes. Both AMT313Q-V and AMT313S-V feature programmable pulse-per-revolution capability and can be configured to 1024 PPR to match the fixed specification of the AMT303-V.

Q: Do the substitute parts meet current compliance standards?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant and maintain unlimited moisture sensitivity rating (MSL 1), meeting current regulatory requirements.

Q: What is the inventory status of substitute parts?

A: AMT313Q-V: 1349 pieces in stock. AMT313S-V: 1045 pieces in stock. Both are active products with established supply availability.
