AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured with 192 pulses per revolution and 12-pole commutation output in a right-angle chassis mount orientation. This encoder is classified as obsolete, making substitute parts necessary for ongoing production and maintenance applications. The AMT303-V operates at 5V supply voltage with an open center actuator design and terminal pin termination, suitable for motor and chassis mounting applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303-V is determined by alignment across the following critical parameters:

• Encoder Type: Incremental
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Detent: No
• Built in Switch: No
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS and REACH Compliance: RoHS3 Compliant, REACH Unaffected

The substitute parts AMT313Q-V and AMT313S-V meet these core mechanical and electrical compatibility criteria. Both are active-status incremental encoders from the AMT31 series with programmable pulse-per-revolution configuration, allowing them to be set to 192 PPR to match the fixed output of the AMT303-V. The primary distinction between substitutes is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the AMT303-V, both AMT313Q-V and AMT313S-V are viable substitutes based on compliance and product status criteria.

AMT313Q-V is the preferred direct replacement when terminal pin termination is required in the existing design. This part maintains identical electrical and mechanical interfaces while offering active product status and ROHS3 compliance. The programmable pulse-per-revolution feature must be configured to 192 PPR during assembly or initialization to match the fixed output of the AMT303-V.

AMT313S-V is suitable for applications where connector-based termination is acceptable or preferred. This variant provides the same electrical performance and compliance certifications as the AMT313Q-V but requires connector interface integration rather than direct pin soldering.

Both substitutes are in active production with higher inventory availability than the obsolete AMT303-V, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be used interchangeably with the AMT303-V?

A: Both parts are mechanically and electrically compatible substitutes. The primary difference is termination style: AMT313Q-V uses terminal pins (direct replacement for pin-based designs), while AMT313S-V uses a connector interface. Selection depends on your existing termination requirements.

Q: What is the significance of the programmable pulses-per-revolution feature in the substitute parts?

A: The AMT303-V has a fixed 192 PPR output, while AMT313Q-V and AMT313S-V feature programmable PPR configuration. To achieve functional equivalence, the substitute part must be programmed to 192 PPR during manufacturing or system initialization.

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

A: The AMT303-V carries RoHS Compliant status, while both substitutes are ROHS3 Compliant. Both maintain REACH Unaffected status. ROHS3 represents a more recent compliance standard and is fully backward compatible with RoHS requirements.

Q: What is the inventory status of these parts?

A: The AMT303-V is obsolete with 787 units in stock. AMT313Q-V has 1349 units available, and AMT313S-V has 1045 units available, both in active production status.

Q: Are there any output configuration differences I should be aware of?

A: The AMT303-V specifies CCW (counter-clockwise) 12-pole commutation output. The substitute parts specify commutation output without directional specification in the provided data. Verify commutation direction compatibility with your application requirements during integration.
