AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 1000 pulses per revolution (PPR) output. This component operates at 5V supply voltage and features an 8-pole right-angle orientation with terminal pin termination, designed for chassis mount and motor applications. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is determined by alignment of the following critical parameters:

• Encoder Type: Incremental operation required
• Supply Voltage: 5V operation mandatory
• Actuator Type: 2mm ~ 8mm open center compatibility
• Mounting Type: Chassis mount and motor mounting capability
• Orientation: Right angle configuration
• Output Type: Commutation output with 8-pole configuration
• Termination Style: Terminal pins or connector-based termination

The substitute parts AMT313Q-V and AMT313S-V satisfy these core electrical and mechanical parameters. Both are active CUI Devices products from the AMT31 series with programmable pulse-per-revolution capability, allowing configuration to match the 1000 PPR specification of the original AMT303-V. The primary distinction between substitutes lies in termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses connector termination.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing long-term availability and supply chain stability compared to the obsolete AMT303-V. Both substitutes maintain full compliance with RoHS3 and REACH requirements, meeting modern regulatory standards.

AMT313Q-V is the preferred substitute when direct termination style compatibility is required, as it maintains terminal pin termination identical to the AMT303-V. The programmable PPR capability allows configuration to the original 1000 PPR specification.

AMT313S-V provides an alternative path when connector-based termination is acceptable or preferred for the application. This variant also supports programmable PPR configuration and offers the same electrical and mechanical compatibility across all other parameters.

Both substitutes require configuration of the programmable PPR setting to 1000 to match the original AMT303-V output specification. Inventory availability is confirmed for both parts, with 1349 units of AMT313Q-V and 1045 units of AMT313S-V in stock.

Frequently Asked Questions (FAQ)

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

A: Both parts satisfy the core electrical and mechanical requirements of the AMT303-V. The primary difference is termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses connector termination. Selection depends on your circuit board design and connector requirements.

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

A: The AMT303-V has a fixed 1000 PPR output. The AMT313Q-V and AMT313S-V feature programmable PPR capability, allowing you to configure the output to 1000 PPR to match the original specification. This programmability provides flexibility for future applications without requiring different hardware.

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

A: The AMT303-V is RoHS Compliant, while both substitutes are ROHS3 Compliant, representing an updated compliance standard. Both substitutes maintain REACH Unaffected status. The substitutes meet current regulatory requirements for new designs and manufacturing.

Q: What is the impact of the obsolete status of AMT303-V?

A: Obsolete status indicates the AMT303-V is no longer manufactured. Using an active substitute part ensures continued availability for repairs, replacements, and new production runs. Both AMT313Q-V and AMT313S-V are active products with confirmed inventory.

Q: Are the actuator and mounting specifications identical across all three parts?

A: Yes. All three parts share identical actuator type (2mm ~ 8mm open center), mounting type (chassis mount, motors), and orientation (right angle), ensuring mechanical compatibility in existing designs.
