AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 512 pulses per revolution with commutation output in counter-clockwise (CCW) orientation. This component is designed for chassis mount and motor applications with right-angle orientation and terminal pin termination. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

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
• Output Type: Commutation
• Supply Voltage: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Manufacturer: CUI Devices

The AMT313Q-V and AMT313S-V both meet these core requirements. The primary distinction between these substitutes and the original part is the pulses per revolution specification: the AMT303-V provides fixed 512 PPR, while the substitute parts feature programmable PPR capability. This programmability allows configuration to match the original 512 PPR specification when required. Both substitute parts are active products with current manufacturing status, addressing the obsolescence of the original component.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are qualified substitutes for the obsolete AMT303-V. Selection between these two options is determined by termination requirements:

AMT313Q-V features terminal pin termination, matching the original AMT303-V configuration. This option provides direct mechanical and electrical compatibility for applications currently using terminal pin connections.

AMT313S-V features connector termination, suitable for applications requiring connector-based integration. This option offers the same electrical and functional specifications as the AMT313Q-V but with alternative connection methodology.

Both substitute parts carry active product status with ROHS3 compliance, providing long-term availability and regulatory alignment superior to the obsolete original component. The programmable PPR capability of both substitutes enables configuration flexibility while maintaining the 512 PPR setting when required for system compatibility.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V and AMT313S-V be configured to match the 512 PPR specification of the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution capability, allowing configuration to the original 512 PPR specification through appropriate programming procedures.

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

A: The termination style differs between the two parts. The AMT313Q-V uses terminal pins, while the AMT313S-V uses a connector interface. All other electrical and mechanical specifications are identical.

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

A: Yes. Both substitute parts share identical mounting type (Chassis Mount, Motors), orientation (Right Angle), and actuator specifications (2mm ~ 8mm Open Center) with the original component.

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 the AMT303-V still available for procurement?

A: The AMT303-V is classified as obsolete. The AMT313Q-V and AMT313S-V are active products with current manufacturing status and recommended for new designs and ongoing system support.
