AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 400 pulses per revolution with 8-pole commutation output in a right-angle orientation. This component is designed for chassis mount and motor applications requiring precise rotational feedback at 5V supply voltage.

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this encoder specification remains functionally required.

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
• Supply Voltage: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Output Type: Commutation
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: RoHS3 or equivalent

The substitute parts AMT313Q-V and AMT313S-V satisfy these core electrical and mechanical compatibility criteria. Both are active-status components from the AMT31 series, ensuring ongoing availability and support. The primary distinction between substitutes relates to termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector interface.

Engineering Selection Recommendations

For applications currently using the AMT303-V, the following selection criteria apply:

AMT313Q-V is the primary substitute when terminal pin termination is required. This part maintains direct mechanical and electrical compatibility with the original design. The programmable pulses-per-revolution feature provides flexibility for future configuration adjustments while supporting the fixed 400 PPR requirement through programming. Active product status ensures long-term availability and manufacturer support.

AMT313S-V is the appropriate substitute when connector-based termination is preferred or when system redesign permits connector integration. This part offers identical electrical and mechanical specifications to AMT313Q-V, with the termination interface as the distinguishing factor. Connector termination may simplify assembly and field replacement procedures in certain applications.

Both substitutes carry ROHS3 compliance, exceeding the RoHS Compliant status of the original part, ensuring regulatory alignment with current environmental standards. Both maintain REACH Unaffected status, confirming no restricted substance concerns.

Frequently Asked Questions (FAQ)

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

A: Both parts satisfy the core electrical and mechanical requirements of the AMT303-V. The primary consideration is termination style: AMT313Q-V uses terminal pins (direct replacement for pin-based designs), while AMT313S-V uses a connector interface (requires connector accommodation in the circuit design).

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

A: The AMT303-V is fixed at 400 PPR. The AMT313Q-V and AMT313S-V offer programmable PPR, allowing configuration to 400 PPR or other values as needed. This feature does not prevent substitution; it provides additional flexibility for system requirements.

Q: Are there compliance differences between the original and substitute parts?

A: The substitute parts carry ROHS3 Compliant status, which represents a more current regulatory standard than the RoHS Compliant designation of the AMT303-V. Both meet or exceed environmental compliance requirements. REACH status is identical across all three parts.

Q: What inventory considerations apply to these substitutes?

A: AMT313Q-V has 1349 units in stock, and AMT313S-V has 1045 units in stock, both classified as active products. The AMT303-V has 866 units available but is obsolete, making the active-status substitutes preferable for new designs and long-term supply assurance.

Q: Does the right-angle orientation remain consistent across all parts?

A: Yes. All three parts—AMT303-V, AMT313Q-V, and AMT313S-V—are configured for right-angle orientation, ensuring mechanical compatibility with existing mounting structures.
