AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 192 pulses per revolution with commutation output in a right-angle chassis mount configuration. This encoder is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring similar functionality.

The AMT303-V operates at 5V supply voltage with an open center actuator (2mm–8mm range) and terminal pin termination. Its primary application is in motor control and chassis-mounted encoder systems requiring fixed 192 PPR resolution.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is based on the following critical parameters that must remain consistent:

• Encoder Type: Incremental operation
• Supply Voltage: 5V
• Actuator Type: 2mm–8mm open center
• Mounting Type: Chassis mount, motors
• Orientation: Right angle
• Output Type: Commutation
• Compliance: RoHS and REACH status

The substitute parts AMT313Q-V and AMT313S-V are qualified alternatives because they maintain these core electrical and mechanical specifications. The primary difference is that substitute parts feature programmable pulses per revolution, whereas the AMT303-V is fixed at 192 PPR. This programmability allows the substitutes to be configured to match the original 192 PPR specification when required.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for direct replacement applications. It maintains terminal pin termination identical to the AMT303-V, ensuring compatibility with existing wiring harnesses and PCB layouts. The programmable PPR capability allows configuration to the original 192 PPR specification. This part is currently in active production status with ROHS3 compliance, providing long-term availability and regulatory alignment.

AMT313S-V is an alternative substitute suitable for applications where connector-based termination is acceptable or preferred. This part also features programmable PPR and active product status. The connector termination may require harness modification compared to the original terminal pin design.

Both substitutes are manufactured by CUI Devices and share the same core electrical and mechanical specifications as the obsolete AMT303-V. Selection between AMT313Q-V and AMT313S-V depends on termination style requirements: terminal pins for direct replacement or connector for new designs.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the original 192 PPR specification?

A: Yes. Both substitute parts feature programmable pulses per revolution and can be configured to 192 PPR to match the AMT303-V output resolution.

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 design. AMT313S-V uses a connector interface, which may require harness redesign.

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

A: Yes. Both substitutes maintain identical mounting type (chassis mount, motors), orientation (right angle), and actuator specifications (2mm–8mm open center), ensuring mechanical compatibility.

Q: What compliance certifications apply to the substitute parts?

A: Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: Why is the AMT303-V classified as obsolete?

A: The AMT303-V is no longer in active production. The substitute parts AMT313Q-V and AMT313S-V represent the current active product line from CUI Devices with equivalent functionality and enhanced programmability.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels are: AMT303-V (1027 pcs), AMT313Q-V (1349 pcs), and AMT313S-V (1045 pcs). All parts are available as new original stock.
