AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 1024 pulses per revolution (PPR) output. 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. Substitute encoders must maintain electrical compatibility across supply voltage, output type, and mechanical mounting specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is determined by the following critical parameters:

• Encoder Type: Must be Incremental
• Output Type: Must support Commutation output
• Supply Voltage: Must operate at 5V
• Actuator Type: Must accommodate 2mm ~ 8mm Open Center shaft
• Mounting Type: Must support Chassis Mount and Motors applications
• Orientation: Must be Right Angle configuration
• Termination Style: Terminal Pins or Connector acceptable
• Regulatory Compliance: RoHS and REACH compliance required

The AMT313Q-V and AMT313S-V are qualified substitutes based on matching these core electrical and mechanical parameters. Both parts feature programmable pulses per revolution capability, which provides operational flexibility beyond the fixed 1024 PPR specification of the AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active product alternatives to the obsolete AMT303-V. Selection between these two substitutes is determined by termination requirements:

AMT313Q-V features Terminal Pins termination, matching the original AMT303-V configuration. This option provides direct compatibility with existing wiring harnesses and connector designs.

AMT313S-V features Connector termination, requiring interface adaptation if the original system uses terminal pin connections. This configuration may offer advantages in applications requiring quick-disconnect capabilities.

Both substitutes maintain full compliance with ROHS3 and REACH regulations, exceeding the RoHS Compliant status of the original part. The programmable pulses per revolution feature of both alternatives allows system configuration to match the original 1024 PPR specification or other operational requirements.

Frequently Asked Questions (FAQ)

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

A: Both parts are electrically and mechanically compatible substitutes. The primary difference is termination style: AMT313Q-V uses Terminal Pins (matching AMT303-V), while AMT313S-V uses Connector termination. Selection depends on your existing connector infrastructure.

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

A: The AMT313Q-V and AMT313S-V offer programmable PPR capability, allowing configuration to match the original 1024 PPR specification or other values as needed. This provides operational flexibility not present in the fixed 1024 PPR AMT303-V.

Q: Are there packaging differences between the substitute parts?

A: AMT313Q-V is supplied in Box packaging, as is AMT313S-V. Both are available in active production with higher inventory levels than the obsolete AMT303-V.

Q: Do the substitute parts meet the same regulatory requirements?

A: Both AMT313Q-V and AMT313S-V exceed the original compliance status. They are ROHS3 Compliant and REACH Unaffected, compared to the AMT303-V which is RoHS Compliant and REACH Unaffected. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What mounting configurations are supported by the substitute encoders?

A: All three parts support identical mounting: Chassis Mount and Motors applications with Right Angle orientation and 2mm ~ 8mm Open Center actuator compatibility.
