AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 400 pulses per revolution with commutation output in counter-clockwise (CCW) orientation. This encoder features a right-angle mounting configuration with a 2mm to 8mm open center actuator and operates at 5V supply voltage. The product is classified as obsolete, necessitating identification of active alternative models that maintain functional and electrical compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303-V is determined by the following critical parameters:

• Encoder Type: Must be Incremental
• Voltage Supply: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Output Type: Must support Commutation output
• Termination Style: Terminal Pins or Connector acceptable

The substitute parts AMT313Q-V and AMT313S-V are qualified alternatives because they maintain identical specifications across all critical mechanical and electrical parameters. The key distinction is that substitute parts feature programmable pulses per revolution capability, allowing configuration to match the fixed 400 PPR specification of the AMT303-V. Both substitutes are active products with current manufacturing status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for applications requiring direct form-factor compatibility. This part maintains terminal pin termination identical to the AMT303-V, ensuring compatibility with existing connector designs and PCB layouts. The programmable pulses per revolution feature allows configuration to the 400 PPR specification of the original part. Product status is active with ROHS3 compliance certification, providing long-term supply assurance and regulatory alignment.

AMT313S-V is an alternative substitute for applications where connector-based termination is acceptable or preferred. This configuration eliminates the need for discrete terminal pin connections and may simplify assembly processes. Programmable PPR capability matches the functional requirements of the AMT303-V. Product status is active with ROHS3 compliance.

Both substitutes are manufactured by CUI Devices, maintaining design continuity within the same product family. Selection between AMT313Q-V and AMT313S-V depends on termination style requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 400 PPR output of the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution capability, allowing configuration to 400 PPR to match the fixed specification of the obsolete AMT303-V.

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

A: The termination style differs. AMT313Q-V uses terminal pins, matching the AMT303-V configuration. AMT313S-V uses a connector-based termination. Both maintain identical electrical and mechanical specifications otherwise.

Q: Are the substitute parts compatible with existing AMT303-V circuit designs?

A: Compatibility depends on termination style. AMT313Q-V with terminal pins provides direct compatibility with designs using the AMT303-V terminal pin configuration. AMT313S-V requires connector interface adaptation.

Q: What compliance certifications apply to the substitute parts?

A: Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Is there a supply advantage to using the substitute parts?

A: Yes. Both substitute parts are active products with current manufacturing status, ensuring ongoing availability. The AMT303-V is obsolete with no new production.
