AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 192 pulses per revolution (PPR), designed for chassis mount and motor applications with right-angle orientation. This encoder features 4-pole commutation output with counter-clockwise (CCW) operation and operates at 5V supply voltage.

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

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on the following critical parameters that determine functional compatibility:

• 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)
• Termination Style: Terminal Pins or Connector (acceptable variations)
• Output Type: Commutation (required match)
• Pulses per Revolution: 192 fixed or Programmable (acceptable variation)

The substitute parts AMT313Q-V and AMT313S-V maintain all critical electrical and mechanical parameters. Both are active products from CUI Devices with current availability. The primary differences are termination style (Terminal Pins vs. Connector) and programmable PPR capability, which provides enhanced flexibility for system integration.

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for applications requiring terminal pin termination. This part maintains identical termination style to the AMT303-V while offering programmable PPR capability. The AMT313Q-V is an active product with current manufacturing status and ROHS3 compliance, providing long-term supply assurance.

AMT313S-V is the alternative substitute for applications where connector termination is acceptable. This part provides the same electrical and mechanical compatibility as the AMT313Q-V but with connector-based termination. The AMT313S-V is also an active product with current availability and ROHS3 compliance.

Both substitute parts exceed the compliance requirements of the obsolete AMT303-V, offering improved regulatory status through ROHS3 certification while maintaining REACH unaffected status.

Frequently Asked Questions (FAQ)

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

A: Both parts are functionally compatible with the AMT303-V in applications requiring incremental commutation output at 5V with right-angle orientation and chassis mount configuration. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface.

Q: What is the advantage of programmable PPR in the substitute parts?

A: The AMT313Q-V and AMT313S-V feature programmable pulses per revolution, allowing configuration to 192 PPR or other values as needed. This provides design flexibility for applications where PPR adjustment may be required without changing the physical encoder.

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

A: The AMT303-V is RoHS Compliant, while both substitute parts are ROHS3 Compliant, representing an enhanced regulatory standard. All three parts maintain REACH Unaffected status and MSL 1 (Unlimited) rating.

Q: Which substitute should be selected for new designs?

A: For new designs with terminal pin requirements, select AMT313Q-V. For applications where connector termination is preferred or specified, select AMT313S-V. Both parts are active products with current manufacturing support.

Q: Are the actuator and mounting specifications identical across all three parts?

A: Yes. All three encoders feature 2mm ~ 8mm open center actuator type, chassis mount and motor mounting capability, and right-angle orientation, ensuring mechanical compatibility in existing installations.
