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 identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

The AMT303-V operates at 5V supply voltage with an open center actuator (2mm–8mm range) and terminal pin termination. Its obsolete status necessitates evaluation of active substitute models that maintain electrical and mechanical compatibility with existing applications.

Key Parameters

Substitute Part Grouping Explanation

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

Core Compatibility Parameters:

• Encoder Type: Incremental
• Voltage Supply: 5V
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Actuator Type: 2mm – 8mm Open Center
• Detent: No
• Built-in Switch: No

Variable Parameters Allowing Substitution:

• Pulses per Revolution: The AMT303-V specifies 1024 PPR; substitute models with programmable PPR capability can be configured to match this specification
• Output Type: Commutation output is maintained; substitute models support commutation configuration
• Termination Style: Both terminal pins and connector termination are acceptable within the AMT31 series
• Product Status: Active substitute models are preferred over obsolete configurations

The AMT313Q-V and AMT313S-V both meet these compatibility criteria while offering programmable pulse-per-revolution functionality, allowing configuration to the original 1024 PPR specification.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for AMT303-V applications requiring terminal pin termination. This part maintains identical termination style to the original while offering active product status and ROHS3 compliance. The programmable PPR capability allows configuration to 1024 pulses per revolution, matching the original specification.

AMT313S-V serves as an alternative substitute for applications where connector termination is acceptable. This part provides the same electrical and mechanical compatibility as the AMT313Q-V but with connector-based termination instead of terminal pins. Active product status and ROHS3 compliance are maintained.

Both substitute parts are currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete AMT303-V.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be directly interchanged with AMT303-V?

A: Both substitute parts are electrically and mechanically compatible with the AMT303-V when configured to 1024 PPR. The primary difference is termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses connector termination. Selection depends on your application's termination requirements.

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

A: The AMT313Q-V and AMT313S-V feature programmable pulse-per-revolution capability, allowing configuration to match the original 1024 PPR specification. This flexibility enables use in multiple applications without requiring different part numbers.

Q: Are there compliance differences between the original and substitute parts?

A: The AMT303-V is RoHS Compliant; both substitute parts are ROHS3 Compliant, representing an enhanced compliance standard. Both maintain REACH Unaffected status. All three parts have MSL 1 (Unlimited) rating.

Q: Why is product status important for this substitution?

A: The AMT303-V is obsolete, meaning CUI Devices no longer manufactures or supports this part. The active status of AMT313Q-V and AMT313S-V ensures continued availability, technical support, and supply chain reliability for new designs and ongoing production.

Q: Which substitute should I select for new designs?

A: For new designs, either AMT313Q-V or AMT313S-V is appropriate based on your termination preference. Terminal pin termination (AMT313Q-V) is recommended if your existing PCB or harness is designed for this connection type. Connector termination (AMT313S-V) may offer advantages in applications requiring frequent disconnection or modular assembly.
