Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is based on the following critical parameters that must align across alternatives:

• Encoder Type: Incremental operation required
• Supply Voltage: 5V operation mandatory
• Actuator Type: 2mm ~ 8mm open center shaft compatibility
• Mounting Configuration: Chassis mount, right-angle orientation
• Output Characteristics: Commutation-based output with compatible pole configuration

The AMT313Q-V and AMT313S-V are identified as equivalent substitutes because they maintain these core electrical and mechanical specifications. Both alternatives feature programmable pulses per revolution, which provides operational flexibility while preserving the fixed 1000 PPR setting capability of the original AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products from CUI Devices and represent current manufacturing alternatives to the obsolete AMT303-V. Selection between these substitutes is determined by termination requirements:

AMT313Q-V features terminal pin termination, matching the original AMT303-V connection method and providing direct mechanical and electrical compatibility for existing circuit board layouts.

AMT313S-V features connector termination, offering modular connection advantages for applications requiring field serviceability or frequent component replacement.

Both alternatives maintain full compliance with RoHS3 and REACH regulations, exceeding the original RoHS compliance standard. The programmable pulses per revolution capability of both substitutes allows configuration to the original 1000 PPR specification, ensuring functional equivalence in signal output.

Frequently Asked Questions (FAQ)

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

A: Both are functionally equivalent substitutes. Selection depends on termination style requirements. AMT313Q-V uses terminal pins; AMT313S-V uses connector termination. Existing circuit board designs using terminal pin connections should specify AMT313Q-V.

Q: What is the primary difference between the two substitute parts?

A: Termination style is the distinguishing factor. AMT313Q-V provides terminal pin connections identical to the original AMT303-V. AMT313S-V provides connector-based termination for modular applications.

Q: Are the substitute parts programmable?

A: Yes. Both AMT313Q-V and AMT313S-V feature programmable pulses per revolution. The original 1000 PPR setting can be configured through programming, maintaining functional equivalence with the fixed-specification AMT303-V.

Q: Do the substitute parts meet current regulatory standards?

A: Both substitutes are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original AMT303-V met RoHS compliance; the substitutes exceed this standard.

Q: What is the inventory status of these alternatives?

A: AMT313Q-V has 1349 pieces in stock. AMT313S-V has 1045 pieces in stock. Both are active products with established supply chains.
