AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 250 pulses per revolution with commutation output in a right-angle chassis mount configuration. This encoder is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The part operates at 5V supply voltage with an open center actuator design and terminal pin termination.

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 (maintained across all substitutes)
• Voltage Supply: 5V (maintained across all substitutes)
• Actuator Type: 2mm ~ 8mm Open Center (maintained across all substitutes)
• Mounting Type: Chassis Mount, Motors (maintained across all substitutes)
• Orientation: Right Angle (maintained across all substitutes)
• Output Type: Commutation (maintained across all substitutes)
• Detent: No (maintained across all substitutes)
• Built-in Switch: No (maintained across all substitutes)

The substitute parts AMT313Q-V and AMT313S-V maintain all critical electrical and mechanical parameters. The primary difference is that these substitutes feature programmable pulses per revolution, whereas the AMT303-V is fixed at 250 PPR. Both substitutes are active products with current manufacturing status, providing long-term availability advantages over the obsolete AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for direct replacement applications. This part maintains terminal pin termination identical to the AMT303-V, ensuring compatibility with existing connector designs. The AMT313Q-V is an active product with ROHS3 compliance, providing superior long-term availability and regulatory alignment compared to the obsolete AMT303-V.

AMT313S-V serves as an alternative substitute when connector-based termination is acceptable or preferred in system redesigns. This part also maintains active product status and ROHS3 compliance. The connector termination style may require interface modifications compared to the terminal pin configuration of the original AMT303-V.

Both substitutes feature programmable pulses per revolution, allowing configuration to 250 PPR to match the original AMT303-V specification or alternative PPR values as required by system requirements.

Frequently Asked Questions (FAQ)

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

A: Both parts maintain identical electrical and mechanical parameters including encoder type, output type, voltage supply, actuator type, mounting type, 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 existing connector interface requirements.

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

A: The AMT303-V is fixed at 250 PPR. The substitute parts AMT313Q-V and AMT313S-V offer programmable PPR capability, allowing configuration to 250 PPR or alternative values. This provides design flexibility for future applications while maintaining compatibility with existing 250 PPR system requirements.

Q: Why is product status important when selecting a substitute?

A: The AMT303-V is classified as obsolete, indicating discontinued manufacturing and limited future availability. Both substitute parts (AMT313Q-V and AMT313S-V) maintain active product status, ensuring reliable long-term supply and continued manufacturer support.

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

A: The AMT303-V carries RoHS Compliant status. Both substitutes carry ROHS3 Compliant status, representing an updated compliance standard. Both parts maintain REACH Unaffected status. The substitutes provide enhanced regulatory alignment with current standards.

Q: Which substitute should be selected for new designs?

A: For new designs, either AMT313Q-V or AMT313S-V is appropriate based on termination requirements. Terminal pin termination (AMT313Q-V) is recommended when existing connector interfaces must be preserved. Connector termination (AMT313S-V) may be preferred in new system designs for improved interface standardization.
