AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 1000 pulses per revolution (PPR) output. This component features a right-angle orientation, chassis mount configuration, and terminal pin termination, operating at 5V supply voltage. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

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
• Mounting Type: Must support Chassis Mount, Motors configuration
• Orientation: Must be Right Angle
• Actuator Type: Must accommodate 2mm ~ 8mm Open Center range
• Output Type: Must provide Commutation output
• Detent and Built-in Switch: Must match (No for both)

The identified substitute parts AMT313Q-V and AMT313S-V satisfy all mandatory compatibility parameters. Both are active-status products from CUI Devices with programmable PPR capability, allowing configuration to match the fixed 1000 PPR specification of the AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are suitable replacements for the obsolete AMT303-V based on electrical and mechanical parameter alignment. The primary distinction between the two substitutes is termination style:

• AMT313Q-V: Terminal Pins termination, matching the original AMT303-V interface
• AMT313S-V: Connector termination, requiring interface adaptation

For direct replacement with minimal system modification, AMT313Q-V is the preferred selection due to identical termination methodology. Both substitutes carry active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

The programmable PPR feature of both substitutes provides configuration flexibility to establish the 1000 PPR output specification of the original component.

Frequently Asked Questions (FAQ)

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

A: Both parts meet the core electrical and mechanical requirements. The selection between them depends on termination interface requirements. AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface.

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

A: The AMT313Q-V and AMT313S-V feature programmable pulses per revolution, allowing configuration to the 1000 PPR specification of the AMT303-V. This flexibility accommodates various system requirements within a single product platform.

Q: Are there packaging differences between the substitute parts?

A: AMT313Q-V is supplied in Box packaging, while AMT313S-V is also supplied in Box packaging. Both are suitable for standard component handling and storage.

Q: Do the substitute parts maintain the same supply voltage requirement?

A: Yes. All three parts operate at 5V supply voltage, ensuring compatibility with existing power distribution systems.

Q: What compliance certifications apply to the substitute parts?

A: Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
