AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 1024 pulses per revolution (PPR) and 6-pole commutation output. This component is designed for chassis mount and motor applications with a right-angle orientation and 5V supply voltage. The AMT303-V is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Must be Incremental
• Voltage Supply: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must support Chassis Mount, Motors
• Orientation: Must be Right Angle
• Output Type: Must support Commutation output
• Pulses per Revolution: Fixed at 1024 PPR for the main part; substitute parts with programmable PPR capability can be configured to 1024 PPR

The AMT313Q-V and AMT313S-V are qualified substitutes because they maintain compatibility across all critical mechanical and electrical parameters. Both parts feature programmable PPR functionality, allowing configuration to match the 1024 PPR specification of the AMT303-V. The primary distinction between substitutes is termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the direct functional replacement for AMT303-V in applications requiring terminal pin termination. Both parts share identical termination methodology, enabling straightforward integration into existing PCB layouts and harness assemblies. The AMT313Q-V maintains active product status with ROHS3 compliance, providing long-term supply chain stability.

AMT313S-V serves as an alternative substitute for applications where connector-based termination is acceptable or preferred. This variant offers the same electrical and mechanical compatibility as AMT313Q-V but with connector termination, which may simplify assembly procedures in certain manufacturing environments.

Both substitute parts feature programmable PPR capability, requiring configuration to 1024 PPR to match the original AMT303-V specification. This programmability provides design flexibility for future applications while maintaining backward compatibility with existing systems.

Frequently Asked Questions (FAQ)

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

A: Both parts are functionally equivalent substitutes when configured to 1024 PPR. The primary difference is termination style: AMT313Q-V uses terminal pins (direct replacement for pin-based connections), while AMT313S-V uses a connector interface (suitable for connector-based assemblies).

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

A: The AMT313Q-V and AMT313S-V feature programmable PPR, allowing configuration to 1024 PPR to match the fixed specification of the obsolete AMT303-V. This programmability does not affect substitution eligibility; both parts must be set to 1024 PPR for equivalent operation.

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

A: The AMT303-V carries RoHS Compliant status, while both substitutes (AMT313Q-V and AMT313S-V) carry ROHS3 Compliant status. Both certifications satisfy RoHS requirements; ROHS3 represents the current compliance standard. All parts maintain identical REACH Unaffected and EAR99 ECCN classifications.

Q: Which substitute should be selected for new designs?

A: Selection depends on termination requirements. For applications using terminal pin connections, select AMT313Q-V. For applications using connector-based termination, select AMT313S-V. Both parts are active products with equivalent electrical performance and mechanical compatibility.

Q: Are there inventory considerations for these substitutes?

A: AMT313Q-V has 1349 units in stock, and AMT313S-V has 1045 units in stock, both in new original condition. The AMT303-V (obsolete) has 862 units available. Substitute parts offer superior long-term availability due to active product status.
