AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 800 pulses per revolution with commutation output in counter-clockwise (CCW) orientation. This component is designed for chassis mount and motor applications with a right-angle orientation and 5V supply voltage. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, redesign, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Incremental (required match)
• Voltage Supply: 5V (required match)
• Actuator Type: 2mm ~ 8mm Open Center (required match)
• Mounting Type: Chassis Mount, Motors (required match)
• Orientation: Right Angle (required match)
• Output Type: Commutation (required match)
• Manufacturer: CUI Devices (same manufacturer ecosystem)

The substitute parts AMT313Q-V and AMT313S-V meet these core electrical and mechanical compatibility criteria. Both are active products from CUI Devices with programmable pulses per revolution capability, allowing configuration to match the original 800 PPR specification when required.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are qualified substitutes for the obsolete AMT303-V based on matching electrical specifications, mechanical form factors, and regulatory compliance.

AMT313Q-V features terminal pin termination, maintaining the same connection style as the original AMT303-V. This part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating.

AMT313S-V provides connector-based termination as an alternative to terminal pins. This part is also active in production with ROHS3 compliance and identical environmental ratings.

Both substitute parts support programmable pulses per revolution, enabling configuration to the original 800 PPR specification. Both maintain 5V supply voltage, identical actuator geometry, right-angle orientation, and chassis mount compatibility required for direct functional replacement.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 800 PPR output of the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution capability, allowing configuration to 800 PPR to match the original specification.

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

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

Q: Are the substitute parts compatible with existing mounting locations designed for the AMT303-V?

A: Yes. Both AMT313Q-V and AMT313S-V maintain the same actuator type (2mm ~ 8mm Open Center), mounting type (Chassis Mount, Motors), and right-angle orientation as the AMT303-V.

Q: Do the substitute parts meet current regulatory requirements?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The original AMT303-V was RoHS compliant.

Q: What supply voltage do the substitute parts require?

A: Both AMT313Q-V and AMT313S-V operate at 5V, matching the original AMT303-V supply voltage requirement.

Q: Are there any differences in environmental ratings between the original and substitute parts?

A: No. All three parts share identical moisture sensitivity level (MSL 1 - Unlimited) and REACH status, indicating equivalent environmental performance characteristics.
