AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 512 pulses per revolution with commutation output in counter-clockwise (CCW) configuration. This component is designed for chassis mount and motor applications with a right-angle orientation and 5V supply voltage. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

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 (maintained across all substitutes)
• Output Type: Commutation configuration (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)
• Termination Style: Varies between Terminal Pins and Connector options
• Pulses per Revolution: Fixed at 512 PPR for AMT303-V; programmable for substitute models

The substitute parts AMT313Q-V and AMT313S-V maintain all critical electrical and mechanical parameters. The primary differences are the programmable pulses per revolution capability and termination style variations, which allow for flexible integration in applications requiring the same core functionality.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing long-term availability compared to the obsolete AMT303-V. Both substitute parts maintain ROHS3 compliance, exceeding the RoHS compliance of the original part.

AMT313Q-V retains the terminal pin termination style of the original AMT303-V, making it the direct mechanical replacement for existing PCB layouts and connector designs.

AMT313S-V provides connector-based termination, offering advantages in modularity and field serviceability for applications where connector-based interfaces are preferred.

The programmable pulses per revolution feature in both substitutes allows configuration to 512 PPR to match the original specification, or alternative PPR values for system optimization without component change.

Frequently Asked Questions (FAQ)

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

A: Both parts maintain identical electrical specifications (5V supply, incremental encoder type, commutation output, 2mm ~ 8mm open center actuator) and mechanical mounting parameters (chassis mount, right angle orientation). 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 significance of programmable pulses per revolution in the substitute parts?

A: The AMT303-V has a fixed 512 PPR specification. The AMT313Q-V and AMT313S-V offer programmable PPR capability, allowing configuration to 512 PPR or other values. This provides design flexibility without requiring component substitution for different resolution requirements.

Q: Are there termination compatibility considerations?

A: Yes. The AMT303-V uses terminal pins for connection. The AMT313Q-V maintains this terminal pin interface for direct replacement. The AMT313S-V uses a connector interface, requiring interface adapter or redesign of connection circuitry.

Q: Do the substitute parts meet current compliance standards?

A: Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original AMT303-V is RoHS compliant but not ROHS3 certified.

Q: What is the inventory status of these parts?

A: AMT303-V (obsolete): 1144 pcs in stock. AMT313Q-V (active): 1349 pcs in stock. AMT313S-V (active): 1045 pcs in stock.
