AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 500 pulses per revolution with commutation output in counter-clockwise direction. The device features a 10-pole right-angle orientation and operates at 5V supply voltage. This part is classified as obsolete, necessitating identification of functionally equivalent alternatives from the active product portfolio to ensure continued system availability and design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on strict alignment with the following critical parameters:

• Encoder Type: Incremental
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• RoHS and REACH Compliance Status
• Manufacturer: CUI Devices (same product family)

The AMT313Q-V and AMT313S-V are functionally equivalent alternatives. Both maintain the same supply voltage, actuator specifications, mounting configuration, and orientation. The primary distinction lies in output configuration flexibility: while the AMT303-V is fixed at 500 PPR, the substitute parts feature programmable pulse-per-revolution settings, allowing adaptation to various system requirements without hardware redesign.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing support, addressing the obsolescence status of the AMT303-V. Selection between these alternatives depends on termination requirements:

• AMT313Q-V: Maintains terminal pin termination, matching the original AMT303-V interface. This option minimizes redesign effort for existing harness and connector configurations.

• AMT313S-V: Provides connector-based termination, offering improved mechanical reliability and simplified assembly procedures in new designs or system revisions.

Both alternatives comply with ROHS3 standards and maintain identical electrical specifications, supply voltage, and mechanical mounting parameters. The programmable PPR capability of both substitutes provides design flexibility for future system adaptations without component replacement.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V directly replace AMT303-V in existing applications?

A: Both parts maintain identical supply voltage (5V), actuator type (2mm ~ 8mm Open Center), mounting configuration (Chassis Mount, Motors), and orientation (Right Angle). The primary consideration is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface. Electrical compatibility is confirmed for both alternatives.

Q: What is the significance of programmable PPR in the substitute parts?

A: The AMT303-V operates at a fixed 500 PPR configuration. The AMT313Q-V and AMT313S-V feature programmable PPR settings, allowing system designers to configure pulse output to match specific application requirements without hardware substitution. This flexibility supports multiple system variants from a single component platform.

Q: Are there compliance differences between the main part and substitutes?

A: The AMT303-V carries RoHS Compliant certification. Both substitute parts (AMT313Q-V and AMT313S-V) meet the more recent ROHS3 Compliant standard. All three parts maintain identical REACH Unaffected and EAR99 ECCN classifications. The upgrade to ROHS3 compliance in substitute parts reflects current manufacturing standards.

Q: Which substitute part should be selected for new designs?

A: Selection depends on termination interface requirements. For applications requiring terminal pin connections, AMT313Q-V is appropriate. For applications where connector-based termination is preferred or specified, AMT313S-V is the suitable choice. Both parts are active products with equivalent electrical and mechanical specifications.

Q: Are there inventory considerations for these substitutes?

A: Current inventory levels are: AMT303-V (1093 pcs), AMT313Q-V (1349 pcs), and AMT313S-V (1045 pcs). All parts are available as new original stock.
