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 chassis mount orientation. This encoder is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

The AMT303-V operates at 5V supply voltage with an open center actuator design (2mm to 8mm range) and terminal pin termination. Its primary application is in motor control and chassis-mounted encoder systems requiring fixed 400 PPR resolution.

Key Parameters

Substitute Part Grouping Explanation

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

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

The substitute parts AMT313Q-V and AMT313S-V satisfy these core compatibility criteria. Both are incremental encoders with commutation output, 5V supply, identical actuator specifications, and matching mechanical mounting characteristics. The primary distinction between the main part and substitutes is the pulses per revolution specification: the AMT303-V provides fixed 400 PPR, while the AMT313 series offers programmable PPR capability, allowing configuration to 400 PPR or other resolutions as required by the application.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V and AMT313S-V are functionally equivalent substitutes for the obsolete AMT303-V. Both alternatives are active products with current manufacturing support and enhanced RoHS3 compliance status.

The primary technical distinction between the substitutes is termination style: AMT313Q-V uses terminal pins (matching the original AMT303-V), while AMT313S-V uses a connector interface. Selection between these two should be based on existing system wiring and connector compatibility requirements.

The programmable PPR capability of the AMT313 series provides operational flexibility. When configured to 400 PPR, these encoders deliver identical functional performance to the fixed 400 PPR AMT303-V. This programmability allows single-part standardization across multiple applications with varying resolution requirements.

Frequently Asked Questions (FAQ)

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

A: Both are functionally equivalent when configured appropriately. The primary consideration is termination style: AMT313Q-V matches the terminal pin termination of the original part, while AMT313S-V uses a connector. System integration requirements determine which substitute is suitable.

Q: What is the significance of programmable PPR in the AMT313 series?

A: The AMT313 encoders allow PPR configuration during setup or programming. When set to 400 PPR, they provide identical resolution to the fixed 400 PPR AMT303-V. This flexibility enables use of a single encoder model across applications with different resolution specifications.

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

A: The AMT303-V is RoHS Compliant, while both AMT313Q-V and AMT313S-V are ROHS3 Compliant. ROHS3 represents an updated compliance standard. Both substitute parts meet or exceed the original compliance requirements.

Q: Does the right-angle orientation remain consistent across all three parts?

A: Yes. All three encoders—AMT303-V, AMT313Q-V, and AMT313S-V—are configured for right-angle orientation with identical chassis mount and motor mounting specifications.

Q: What inventory status should influence component selection?

A: The AMT303-V is obsolete with limited remaining stock (1001 pcs). Both AMT313Q-V (1349 pcs) and AMT313S-V (1045 pcs) are active products with current manufacturing availability, making them preferred for new designs and ongoing procurement.
