AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 800 pulses per revolution with commutation output in counter-clockwise direction and 4-pole right-angle orientation. This component 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 design continuity and ensure component availability for new production runs, repairs, and system upgrades where this encoder specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is determined by the following critical parameters that must remain consistent across equivalent parts:

• Encoder Type: Incremental (fixed requirement)
• Voltage Supply: 5V (fixed requirement)
• Actuator Type: 2mm–8mm Open Center (fixed requirement)
• Mounting Type: Chassis Mount, Motors (fixed requirement)
• Orientation: Right Angle (fixed requirement)
• Output Type: Commutation with 4-pole configuration (fixed requirement)
• Pulses per Revolution: 800 PPR for AMT303-V (variable for programmable alternatives)

The substitute parts AMT313Q-V and AMT313S-V are functionally equivalent because they maintain all critical fixed parameters. Both substitutes feature programmable pulses per revolution, allowing configuration to 800 PPR to match the original specification. The primary differences are termination style (Terminal Pins vs. Connector) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for AMT303-V. Both parts share identical termination style (Terminal Pins) and maintain all critical electrical and mechanical parameters. The AMT313Q-V is currently in active production status with ROHS3 compliance, providing long-term component availability and regulatory alignment. The programmable pulses per revolution feature allows configuration to 800 PPR, matching the original specification.

AMT313S-V is an alternative substitute with identical electrical and mechanical specifications but features connector-based termination instead of terminal pins. This part is suitable only when connector termination is compatible with the application circuit design. The AMT313S-V is also in active production with ROHS3 compliance.

Both substitutes provide superior compliance status (ROHS3 vs. RoHS Compliant) and active product lifecycle support compared to the obsolete AMT303-V.

Frequently Asked Questions (FAQ)

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

A: Both parts are functionally equivalent in terms of encoder type, output configuration, voltage supply, actuator type, mounting, and orientation. The primary difference is termination style. AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector. Selection depends on circuit board design compatibility.

Q: What is the significance of "Programmable" pulses per revolution in the substitute parts?

A: The AMT313Q-V and AMT313S-V feature programmable PPR, allowing configuration to 800 PPR to match the fixed 800 PPR specification of AMT303-V. This flexibility provides design continuity while offering future adaptability for different resolution requirements.

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

A: Yes. The AMT303-V carries RoHS Compliant status, while both substitutes (AMT313Q-V and AMT313S-V) are ROHS3 Compliant, representing a more recent regulatory standard. Both meet REACH Unaffected and EAR99 ECCN classifications.

Q: Which substitute should be selected for new designs?

A: For applications requiring terminal pin termination, select AMT313Q-V. For applications compatible with connector termination, either AMT313Q-V or AMT313S-V may be used. Both are in active production and provide superior lifecycle support compared to the obsolete AMT303-V.

Q: Are there inventory considerations for these substitutes?

A: Current inventory shows AMT313Q-V with 1349 units and AMT313S-V with 1045 units in stock, compared to 673 units of the obsolete AMT303-V. Both substitutes offer improved availability for ongoing production requirements.
