AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 96 pulses per revolution with commutation output in counter-clockwise direction. This encoder features a 10-pole right-angle orientation and operates at 5V supply voltage. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is based on the following critical parameters that must remain consistent across alternative components:

• Encoder Type: Incremental operation
• Supply Voltage: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Output Type: Commutation configuration
• Mechanical Interface: Compatible with existing mechanical mounting

The substitute parts AMT313Q-V and AMT313S-V maintain these core electrical and mechanical specifications. Both alternatives feature programmable pulses per revolution capability, which provides functional equivalence to the fixed 96 PPR configuration of the AMT303-V when programmed to the same resolution. Both substitute parts are active products with current manufacturing status, addressing the obsolescence of the original AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for AMT303-V applications requiring terminal pin termination. This part maintains identical termination style to the original component, minimizing integration modifications. The programmable pulses per revolution feature allows configuration to 96 PPR, matching the original specification. AMT313Q-V holds active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

AMT313S-V serves as an alternative when connector-based termination is acceptable or preferred. This variant provides the same electrical and mechanical compatibility as AMT313Q-V but uses a connector interface instead of terminal pins. Selection of AMT313S-V requires verification that the connector type is compatible with existing system wiring and mechanical assembly.

Both substitute parts are manufactured by CUI Devices and carry identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification). The choice between AMT313Q-V and AMT313S-V depends solely on termination style requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be directly substituted for AMT303-V without circuit modifications?

A: Both parts maintain identical electrical specifications (5V supply, incremental encoder type, commutation output, open center actuator). The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector. Direct substitution is possible with AMT313Q-V. AMT313S-V requires connector compatibility verification.

Q: How does the programmable pulses per revolution feature affect substitution?

A: The AMT303-V operates at a fixed 96 PPR configuration. The substitute parts AMT313Q-V and AMT313S-V feature programmable PPR capability, which must be configured to 96 PPR to match the original specification. This configuration is performed during system initialization and does not affect mechanical or electrical compatibility.

Q: Are there packaging differences between the substitute parts?

A: AMT313Q-V and AMT313S-V are supplied in box packaging. Both parts maintain the same mechanical form factor and mounting interface as the AMT303-V, ensuring compatibility with existing chassis mount and motor integration points.

Q: What is the significance of the product status change from Obsolete to Active?

A: The AMT303-V is classified as obsolete, indicating discontinued manufacturing. The substitute parts AMT313Q-V and AMT313S-V are active products with current production, ensuring availability for new procurement and system support. This status change does not affect electrical or mechanical compatibility.

Q: Do the substitute parts meet the same compliance requirements?

A: Both AMT313Q-V and AMT313S-V meet ROHS3 compliance (an enhanced version of RoHS), REACH unaffected status, and EAR99 ECCN classification, matching or exceeding the compliance profile of the original AMT303-V.
