AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 1024 pulses per revolution with commutation output in a right-angle chassis mount configuration. This encoder is classified as obsolete, making equivalent substitute parts necessary for ongoing system support and new designs requiring similar functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is based on the following critical parameters that must align 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
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts AMT313Q-V and AMT313S-V maintain compatibility with these core parameters. Both substitutes feature programmable pulses per revolution, which encompasses the fixed 1024 PPR specification of the AMT303-V. The primary distinction between substitutes lies in 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, the following selection criteria apply:

AMT313Q-V is the direct functional equivalent when terminal pin termination is required. This part maintains identical electrical and mechanical interfaces while offering active product status and ROHS3 compliance. The programmable pulses per revolution feature provides configuration flexibility beyond the fixed 1024 PPR specification.

AMT313S-V serves as an alternative when connector-based termination is acceptable or preferred. This part provides identical functional performance with the added benefit of standardized connector interface, which may simplify integration in systems designed for modular component replacement.

Both substitute parts carry active product status, ensuring long-term availability and supply chain stability compared to the obsolete AMT303-V.

Frequently Asked Questions (FAQ)

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

A: Both parts are functionally equivalent to the AMT303-V in terms of encoder type, output characteristics, supply voltage, mounting configuration, and orientation. The primary difference is termination style: AMT313Q-V uses terminal pins (direct replacement), while AMT313S-V uses a connector interface. Selection depends on your system's termination requirements.

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

A: The AMT303-V operates at a fixed 1024 PPR. The substitute parts AMT313Q-V and AMT313S-V feature programmable PPR, which can be configured to 1024 PPR to match the original specification. This programmability provides additional flexibility for future applications without requiring different hardware.

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

A: The AMT303-V is RoHS Compliant, while both substitutes (AMT313Q-V and AMT313S-V) are ROHS3 Compliant, representing an enhanced compliance standard. Both parts maintain identical Moisture Sensitivity Level (1 - Unlimited) and REACH Unaffected status.

Q: Which substitute should I select for a direct pin-for-pin replacement?

A: AMT313Q-V is the appropriate choice for direct replacement when terminal pin termination is required. It maintains the same termination style as the AMT303-V while providing active product status and modern compliance certifications.

Q: What is the inventory status of these parts?

A: AMT303-V has 1039 pieces in stock (obsolete status). AMT313Q-V has 1349 pieces available, and AMT313S-V has 1045 pieces available, both with active product status.
