AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 96 pulses per revolution (PPR), designed for chassis mount and motor applications with right-angle orientation. The encoder features commutation output with counter-clockwise (CCW) operation and 2-pole configuration, operating at 5V supply voltage with an open center actuator (2mm–8mm range).

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for applications requiring incremental encoder solutions with compatible electrical and mechanical specifications.

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)
• Output Type: Commutation output capability
• Voltage – Supply: 5V operation
• Actuator Type: 2mm–8mm open center configuration
• Mounting Type: Chassis mount and motor applications
• Orientation: Right angle mounting
• Termination Style: Compatible electrical connection methods

The substitute parts AMT313Q-V and AMT313S-V share these core electrical and mechanical characteristics with the AMT303-V. Both substitutes are active products from CUI Devices, offering enhanced functionality through programmable pulses per revolution while maintaining compatibility with the original application requirements.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is suitable for applications requiring terminal pin termination. This substitute maintains the same electrical interface as the AMT303-V while offering programmable PPR capability. The AMT313Q-V is an active product with ROHS3 compliance, providing long-term availability and regulatory alignment.

AMT313S-V is suitable for applications where connector-based termination is preferred or required. This substitute provides the same core functionality as the AMT303-V with the added benefit of connector termination and programmable PPR configuration. The AMT313S-V is an active product with ROHS3 compliance.

Both substitutes are compliant with REACH regulations and carry the same ECCN and HTSUS classifications as the original part, ensuring regulatory consistency for procurement and export purposes.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V directly replace AMT303-V in existing applications?

A: Both substitutes share the same core electrical specifications (5V supply, incremental encoder type, commutation output, 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. Verify termination compatibility with your application's wiring harness before substitution.

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

A: The AMT313Q-V and AMT313S-V offer programmable pulses per revolution, whereas the AMT303-V is fixed at 96 PPR. This allows configuration flexibility for different resolution requirements without changing the physical encoder. If your application requires exactly 96 PPR, the substitutes can be programmed to this value.

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

A: The AMT303-V is RoHS Compliant, while both substitutes (AMT313Q-V and AMT313S-V) are ROHS3 Compliant. Both are REACH Unaffected. The substitutes provide enhanced regulatory compliance for new designs and long-term supply chain stability.

Q: Which substitute should I select based on termination requirements?

A: Select AMT313Q-V if your application uses terminal pin connections. Select AMT313S-V if your application requires connector-based termination. Both provide identical electrical functionality and mechanical mounting compatibility.

Q: Is the AMT303-V output configuration (CCW, 2 Pole) maintained in the substitutes?

A: Both substitutes support commutation output. Verify that your application's control electronics can accept the programmable commutation configuration of the AMT313 series, as the specific CCW and 2-pole settings may require reconfiguration during implementation.
