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 12-pole commutation output in a right-angle orientation. This component is designed for chassis mount and motor applications requiring precise rotational feedback at 5V supply voltage.

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

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on the following critical parameters that must align for functional equivalence:

• Encoder Type: Incremental (required match)
• Voltage Supply: 5V (required match)
• Actuator Type: 2mm ~ 8mm Open Center (required match)
• Mounting Type: Chassis Mount, Motors (required match)
• Orientation: Right Angle (required match)
• Output Type: Commutation (required match)
• Termination Style: Compatible with system integration

The substitute parts AMT313Q-V and AMT313S-V share all critical mechanical and electrical parameters with the AMT303-V. Both are active-status products from CUI Devices with identical supply voltage, actuator configuration, mounting type, and orientation. The key difference is that substitute parts feature programmable pulses per revolution, whereas the AMT303-V is fixed at 250 PPR. When the application requires exactly 250 PPR output, the substitute parts must be programmed to this specification.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are suitable substitutes for the obsolete AMT303-V based on matched electrical and mechanical specifications. The primary selection criterion between the two substitutes is termination style:

• AMT313Q-V: Terminal Pins termination. Select this substitute when direct pin connection to existing PCB or harness is required.
• AMT313S-V: Connector termination. Select this substitute when connector-based integration is preferred or when the original system uses connector-based attachment.

Both substitute parts carry active product status and meet current RoHS3 compliance requirements, providing long-term availability and regulatory alignment. The programmable PPR feature of both substitutes allows configuration to the original 250 PPR specification, ensuring functional compatibility with existing control systems and firmware.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V directly replace AMT303-V without modification?

A: Both substitutes match all critical electrical and mechanical parameters. The primary difference is termination style (terminal pins vs. connector). Physical integration may require connector or pin adapter depending on the original system design. The programmable PPR feature must be configured to 250 PPR to match the original fixed specification.

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

A: Both parts are functionally identical in encoder operation, output type, voltage, and mechanical configuration. The difference is termination style: AMT313Q-V uses terminal pins, while AMT313S-V uses a connector interface. Select based on your system's connection requirements.

Q: Why do the substitute parts have programmable PPR instead of fixed 250 PPR?

A: The AMT313 series offers programmable PPR as a design feature, providing flexibility across multiple applications. When substituting for the fixed 250 PPR AMT303-V, program the substitute to 250 PPR during system integration.

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

A: The AMT303-V is RoHS Compliant. Both substitutes are ROHS3 Compliant, which represents an updated standard. All three parts are REACH Unaffected and carry the same ECCN and HTSUS classifications, ensuring regulatory compatibility.

Q: What inventory status should I expect for these substitute parts?

A: AMT303-V is obsolete with limited remaining stock (1012 pcs). Both substitute parts carry active product status with current inventory availability (AMT313Q-V: 1349 pcs; AMT313S-V: 1045 pcs), ensuring reliable sourcing for new production and replacement applications.
