AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 250 pulses per revolution (PPR) output. This encoder features a right-angle orientation, chassis mount configuration, and operates at 5V supply voltage. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations. Substitute parts must maintain compatibility across electrical specifications, mechanical mounting, and output characteristics to ensure direct replacement capability.

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 be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Output Type: Must support Commutation output

The substitute parts AMT313Q-V and AMT313S-V satisfy these core electrical and mechanical requirements. Both alternatives feature programmable pulses per revolution capability, which provides functional equivalence to the fixed 250 PPR specification of the AMT303-V through configuration. The primary distinction between substitutes relates to 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 primary substitute for direct replacement applications. This part maintains terminal pin termination identical to the AMT303-V, minimizing circuit board modifications. The programmable PPR feature allows configuration to 250 PPR, matching the original specification. The part is currently in active production status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.

AMT313S-V serves as an alternative where connector-based termination is acceptable or preferred. This configuration eliminates soldered connections, potentially improving serviceability in field applications. Connector termination requires interface adapter consideration during integration. This part is also in active production with ROHS3 compliance.

Both substitutes provide superior long-term supply chain stability compared to the obsolete AMT303-V, with significantly higher inventory availability (1349 and 1045 units respectively versus 796 units for the original part).

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 compatibility requirements. Selection depends on termination style requirements. AMT313Q-V matches the terminal pin interface of the original; AMT313S-V requires connector accommodation.

Q: How is the 250 PPR specification maintained with programmable alternatives?

A: The AMT313Q-V and AMT313S-V feature programmable PPR configuration. The encoder must be programmed to 250 PPR during system initialization to match the fixed specification of the AMT303-V.

Q: What is the difference between terminal pin and connector termination?

A: Terminal pins require direct soldering to circuit board traces. Connector termination uses a mating connector interface, allowing tool-free disconnection and replacement without desoldering.

Q: Are there supply chain advantages to using substitute parts?

A: Yes. Both AMT313Q-V and AMT313S-V are in active production status with substantially higher inventory levels, providing improved availability and reduced lead times compared to the obsolete AMT303-V.

Q: Do the substitutes maintain RoHS compliance?

A: Both substitutes carry ROHS3 certification, meeting current regulatory requirements. The original AMT303-V carries RoHS Compliant status. All three parts are REACH Unaffected.
