AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 400 pulses per revolution with commutation output in a right-angle orientation. This component is designed for chassis mount and motor applications with a 5V supply requirement and open center actuator (2mm–8mm range).

The AMT303-V has reached obsolete product status. Identifying equivalent substitute parts ensures continued availability for maintenance, repair, and new production applications where this encoder specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V must satisfy the following core parameters to ensure functional compatibility:

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

The substitute parts identified—AMT313Q-V and AMT313S-V—maintain these core electrical and mechanical parameters. The primary difference is that substitute parts feature programmable pulses per revolution, whereas the AMT303-V is fixed at 400 PPR. Both substitutes are active products with current manufacturing status and improved compliance certifications (ROHS3).

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for applications requiring terminal pin termination. This part maintains identical termination style to the AMT303-V while offering programmable PPR configuration and active product status. ROHS3 compliance provides enhanced regulatory alignment for new designs and long-term supply chain stability.

AMT313S-V is suitable for applications where connector-based termination is acceptable. This variant also provides programmable PPR and active product status with ROHS3 compliance. The connector termination may require interface redesign depending on existing circuit board layouts.

Both substitutes support the fixed 400 PPR configuration through programming, ensuring functional equivalence to the AMT303-V in applications where this specific pulse count is required. Active product status ensures continued availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be used as direct replacements for AMT303-V?

A: Both parts satisfy the core electrical and mechanical parameters: incremental encoder type, commutation output, 5V supply, open center actuator, right-angle orientation, and identical mounting specifications. The primary difference is termination style (terminal pins vs. connector) and programmable PPR capability. AMT313Q-V provides terminal pin compatibility; AMT313S-V requires connector interface compatibility.

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

A: The AMT313Q-V and AMT313S-V feature programmable pulses per revolution, allowing configuration to 400 PPR to match the fixed AMT303-V specification. This flexibility provides functional equivalence while offering design advantages for future applications requiring different pulse counts.

Q: Are there compliance differences between the main part and substitutes?

A: The AMT303-V carries RoHS Compliant status, while both substitutes (AMT313Q-V and AMT313S-V) carry ROHS3 Compliant status, representing an enhanced regulatory standard. Both maintain REACH Unaffected status. The upgraded compliance in substitutes supports modern regulatory requirements.

Q: Does termination style affect electrical performance?

A: Termination style (terminal pins vs. connector) affects physical integration and circuit board interface design but does not alter electrical performance or signal characteristics. Selection depends on existing system architecture and connector availability.

Q: What is the inventory status of these parts?

A: AMT303-V (obsolete): 1027 pcs in stock. AMT313Q-V (active): 1349 pcs in stock. AMT313S-V (active): 1045 pcs in stock. Active product status for substitutes ensures continued supply availability.
