AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 192 pulses per revolution (PPR), designed for chassis mount and motor applications with right-angle orientation. This encoder features 2-pole commutation output with counter-clockwise (CCW) operation and operates at 5V supply voltage.

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring this encoder specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• Encoder Type: Incremental
• Output Type: Commutation
• Voltage - Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Detent: No
• Built-in Switch: No
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: Compliant

Substitution Allowance:

• Pulses per Revolution: The AMT303-V specifies 192 PPR as a fixed parameter. Substitute parts with programmable PPR capability can be configured to match this specification, making them functionally equivalent.
• Termination Style: Both terminal pins and connector terminations are acceptable substitutes, as they serve the same electrical function with different physical interfaces.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active product alternatives to the obsolete AMT303-V. Both substitute parts meet all core electrical and mechanical compatibility requirements.

AMT313Q-V: Maintains terminal pin termination style identical to the AMT303-V, providing direct mechanical and electrical interface compatibility. This part is suitable for applications requiring minimal integration changes.

AMT313S-V: Provides connector-based termination, offering an alternative interface option. This part is suitable for applications where connector-based termination is preferred or required.

Both substitute parts feature programmable PPR capability, allowing configuration to the 192 PPR specification of the original AMT303-V. Both parts carry ROHS3 compliance, exceeding the RoHS compliance of the original part, and maintain identical MSL ratings and supply voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be directly substituted for AMT303-V?

A: Both parts meet the core electrical and mechanical compatibility criteria. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface. Selection depends on your application's termination requirements.

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

A: The AMT303-V operates at a fixed 192 PPR. The substitute parts (AMT313Q-V and AMT313S-V) feature programmable PPR, meaning they can be configured to output 192 PPR to match the original specification. This flexibility makes them functionally equivalent while providing additional configuration options.

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

A: The substitute parts carry ROHS3 compliance, which represents a more recent RoHS standard than the RoHS compliance of the AMT303-V. Both meet regulatory requirements. Moisture sensitivity levels and REACH status remain identical across all three parts.

Q: Which substitute part should I select for my application?

A: Choose AMT313Q-V if your application uses terminal pin connections. Choose AMT313S-V if your application requires or prefers connector-based termination. Both parts are electrically and mechanically compatible with the original AMT303-V specification when configured to 192 PPR.

Q: What is the inventory status of these substitute parts?

A: AMT313Q-V has 1349 pieces in stock. AMT313S-V has 1045 pieces in stock. Both are classified as active products with ongoing availability.
