AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 200 pulses per revolution (PPR) output. This encoder features a right-angle orientation, chassis mount configuration, and terminal pin termination, operating at 5V supply voltage. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is 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
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Manufacturer: CUI Devices (same product family)
• RoHS Compliance: RoHS3 or equivalent

The AMT313Q-V and AMT313S-V are active product alternatives within the CUI Devices AMT31 series. Both maintain functional equivalence through identical supply voltage, actuator specifications, mounting configuration, and orientation. The primary distinction between these substitutes is termination style: AMT313Q-V uses terminal pins (matching the original AMT303-V), while AMT313S-V uses connector termination.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete AMT303-V, the AMT313Q-V is the primary substitute due to identical termination style (terminal pins), ensuring direct compatibility with existing wiring and connector interfaces. Both substitute parts maintain active product status with CUI Devices, providing long-term availability and supply chain stability.

The AMT313S-V serves as an alternative where connector-based termination is acceptable or preferred in system redesigns. Both substitutes meet ROHS3 compliance requirements, exceeding the RoHS compliance level of the original part.

The programmable pulses per revolution feature in both substitute parts provides design flexibility beyond the fixed 200 PPR specification of the AMT303-V, allowing configuration to match system requirements without component substitution.

Frequently Asked Questions (FAQ)

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

A: Both parts are functionally equivalent substitutes. AMT313Q-V is the direct replacement for terminal pin applications. AMT313S-V requires connector interface compatibility in the host system.

Q: What is the primary difference between AMT313Q-V and AMT313S-V?

A: Termination style differs: AMT313Q-V uses terminal pins; AMT313S-V uses connector termination. All other electrical and mechanical parameters are identical.

Q: Does the programmable PPR feature of substitute parts affect compatibility?

A: The programmable feature provides additional capability. Both substitutes can be configured to match the 200 PPR output of the original AMT303-V or adjusted for alternative pulse rates as system requirements dictate.

Q: Are there supply voltage or mounting differences between the original and substitute parts?

A: No. Supply voltage (5V), actuator type (2mm ~ 8mm open center), mounting configuration (chassis mount), and orientation (right angle) are identical across all three parts.

Q: What is the RoHS compliance status of the substitute parts?

A: Both AMT313Q-V and AMT313S-V are ROHS3 compliant, meeting current regulatory requirements and exceeding the RoHS compliance level of the obsolete AMT303-V.
