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 maintenance and new design implementations. The part operates at 5V supply voltage with an open center actuator design and terminal pin termination.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are selected based on the following critical parameters that must align for functional compatibility:

• Encoder Type: Incremental
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Output Type: Commutation
• RoHS Compliance: Required

The AMT313Q-V and AMT313S-V both meet these core electrical and mechanical requirements. The primary distinction between these substitutes is the pulses per revolution specification: while the original AMT303-V provides fixed 1024 PPR, the substitute parts feature programmable PPR capability, allowing configuration to match the original 1024 PPR setting or other required values within the encoder's programmable range.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active product alternatives to the obsolete AMT303-V. Selection between these substitutes depends on termination requirements:

AMT313Q-V maintains terminal pin termination identical to the original AMT303-V, providing direct mechanical and electrical compatibility with existing connector designs.

AMT313S-V features connector-based termination, requiring interface modification but offering standardized connector-based integration for new designs.

Both substitutes carry ROHS3 compliance, exceeding the RoHS compliance of the original part. The programmable PPR capability of both substitutes allows configuration to the original 1024 PPR specification, ensuring functional equivalence in applications requiring this specific resolution.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 1024 PPR output of the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution capability, allowing configuration to 1024 PPR to match the original AMT303-V specification.

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

A: The termination style differs. AMT313Q-V uses terminal pins (matching the original AMT303-V), while AMT313S-V uses a connector interface. Electrical and mechanical specifications are otherwise equivalent.

Q: Are the substitute parts compatible with existing AMT303-V mounting locations?

A: Yes. Both substitutes share identical mounting type (Chassis Mount, Motors), orientation (Right Angle), and actuator specifications (2mm ~ 8mm Open Center), ensuring mechanical compatibility with original mounting designs.

Q: Do the substitute parts meet current compliance standards?

A: Yes. Both AMT313Q-V and AMT313S-V carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

Q: What supply voltage do the substitute parts require?

A: Both substitutes operate at 5V supply voltage, matching the original AMT303-V specification.
