AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 250 pulses per revolution with commutation output in counter-clockwise (CCW) orientation. This encoder features a 12-pole right-angle design with 5V supply voltage and chassis mount capability for motor applications. The product is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional and mechanical compatibility for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder type (Incremental)
• Supply voltage (5V)
• Actuator type (2mm ~ 8mm Open Center)
• Mounting type (Chassis Mount, Motors)
• Orientation (Right Angle)
• Output type (Commutation)
• Regulatory compliance (RoHS, REACH)

The identified substitutes, AMT313Q-V and AMT313S-V, are both active CUI Devices products within the AMT31 series. These parts maintain identical electrical specifications and mechanical form factors. The primary distinction between substitutes lies in termination style and pulses per revolution configuration. AMT313Q-V and AMT313S-V feature programmable pulse per revolution settings, allowing configuration to match the original 250 PPR specification of the AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing long-term availability and supply chain stability compared to the obsolete AMT303-V. Both substitutes maintain full compliance with RoHS3 and REACH regulations, exceeding the original RoHS compliance level of the main part.

The selection between AMT313Q-V and AMT313S-V depends on termination requirements. AMT313Q-V provides terminal pin termination, matching the original AMT303-V configuration. AMT313S-V offers connector-based termination, suitable for applications requiring quick-disconnect capability.

The programmable pulses per revolution feature in both substitutes provides operational flexibility. Configuration to 250 PPR aligns the substitute parts with the original AMT303-V specification for direct functional equivalence in existing system designs.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 250 PPR specification of the AMT303-V?

A: Yes. Both substitutes feature programmable pulses per revolution settings, allowing configuration to 250 PPR to match the original part specification.

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

A: The termination style differs. AMT313Q-V uses terminal pins, while AMT313S-V uses a connector interface. Both maintain identical electrical and mechanical specifications.

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

A: Yes. Both AMT313Q-V and AMT313S-V maintain identical actuator type (2mm ~ 8mm Open Center), mounting type (Chassis Mount, Motors), and orientation (Right Angle) specifications, ensuring mechanical compatibility with original mounting configurations.

Q: What regulatory advantages do the substitute parts offer?

A: Both AMT313Q-V and AMT313S-V comply with ROHS3 standards, representing an upgrade from the original RoHS compliance level. Both maintain REACH Unaffected status, matching the original part's regulatory standing.

Q: Why is the AMT303-V classified as obsolete?

A: Product obsolescence reflects manufacturing discontinuation by CUI Devices. The active substitute parts within the AMT31 series provide equivalent functionality with enhanced programmability and current production support.
