AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 512 pulses per revolution with commutation output in a right-angle chassis mount configuration. This encoder is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations. The part operates at 5V supply voltage with an open center actuator design and terminal pin termination.

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on the following critical parameters that determine functional compatibility:

• Encoder Type: Incremental (maintained across all substitutes)
• Output Type: Commutation output (maintained across all substitutes)
• Supply Voltage: 5V (maintained across all substitutes)
• Actuator Type: 2mm ~ 8mm Open Center (maintained across all substitutes)
• Mounting Type: Chassis Mount, Motors (maintained across all substitutes)
• Orientation: Right Angle (maintained across all substitutes)
• Pulses per Revolution: The AMT303-V specifies 512 PPR fixed; substitute parts feature programmable PPR capability, allowing configuration to 512 PPR or other values as required

The AMT313Q-V and AMT313S-V are qualified substitutes due to matching electrical characteristics, mechanical form factor, and mounting compatibility. The primary distinction is the programmable PPR feature in substitutes versus the fixed 512 PPR in the original part.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active production parts with current availability, addressing the obsolescence status of the AMT303-V. Selection between these substitutes is determined by termination requirements:

AMT313Q-V features terminal pin termination, matching the original AMT303-V termination style. This substitute provides direct mechanical and electrical compatibility for applications currently using terminal pin connections.

AMT313S-V features connector termination, suitable for applications requiring quick-disconnect or modular connection architecture. This substitute maintains all electrical and mechanical parameters but requires connector interface adaptation.

Both substitutes carry ROHS3 compliance certification, exceeding the RoHS compliance of the original part. Programmable PPR capability in both substitutes allows configuration to the original 512 PPR specification or alternative values as system requirements evolve.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 512 PPR specification of AMT303-V?

A: Yes. Both substitute parts feature programmable PPR capability, allowing configuration to 512 PPR or other values. Configuration method and available PPR options are specified in the respective product datasheets.

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

A: The termination style differs. AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface. All other electrical and mechanical parameters are identical.

Q: Are the substitute parts pin-compatible with the original AMT303-V?

A: AMT313Q-V maintains terminal pin termination compatible with AMT303-V applications. AMT313S-V uses connector termination and requires interface adaptation. Detailed pinout specifications are available in product datasheets.

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. The original AMT303-V carries RoHS Compliant status.

Q: What is the supply voltage requirement for substitute parts?

A: Both AMT313Q-V and AMT313S-V operate at 5V supply voltage, matching the original AMT303-V specification.

Q: Are there inventory considerations for these substitutes?

A: AMT313Q-V has 1349 units in stock and AMT313S-V has 1045 units in stock, both classified as active production parts with ongoing availability.
