AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 250 pulses per revolution with commutation output in a 4-pole right angle orientation. This encoder is designed for chassis mount and motor applications with a 5V supply requirement and open center actuator (2mm–8mm range).

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications currently utilizing this encoder model.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303-V is determined by the following critical parameters:

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

The substitute parts AMT313Q-V and AMT313S-V satisfy all mandatory compatibility parameters. Both are active-status encoders from the AMT31 series with programmable pulses per revolution, allowing configuration to match the 250 PPR specification of the AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are suitable substitutes for the obsolete AMT303-V based on electrical and mechanical compatibility. Both substitute parts carry active product status, ensuring ongoing availability and support.

AMT313Q-V maintains terminal pin termination, matching the original AMT303-V configuration. This option minimizes integration changes.

AMT313S-V uses connector termination instead of terminal pins. This option may require interface modifications depending on the application's existing wiring harness or PCB design.

Both substitutes are ROHS3 compliant, exceeding the RoHS compliance level of the original part. The programmable pulses per revolution feature in both substitutes allows configuration to the 250 PPR specification required by the AMT303-V application.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 250 PPR output of the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution, allowing configuration to 250 PPR to match the original encoder specification.

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

A: The termination style differs. AMT313Q-V uses terminal pins (matching the AMT303-V), while AMT313S-V uses a connector interface. Selection depends on the application's wiring and integration requirements.

Q: Are the substitute parts compatible with 5V supply systems?

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

Q: Do the substitute parts support the same mounting configuration?

A: Yes. Both substitutes are configured for chassis mount and motor applications with right angle orientation, identical to the AMT303-V.

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 standards.
