AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 200 pulses per revolution (PPR) output. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The encoder features a right-angle orientation with chassis mount capability, 5V supply voltage, and terminal pin termination. Due to its obsolete status, equivalent alternatives with compatible electrical and mechanical specifications are required for procurement and system continuity.

Key Parameters

Substitute Part Grouping Explanation

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

Primary 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
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: RoHS3 or equivalent

Variable Parameter:

• Pulses per Revolution: The AMT303-V specifies 200 PPR as a fixed value. Substitute parts with programmable PPR capability maintain compatibility when configured to 200 PPR operation.

Termination Consideration:

• The AMT303-V uses Terminal Pins termination. Substitute AMT313S-V uses Connector termination, requiring interface adaptation but maintaining electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for direct replacement applications. This part maintains identical termination style (Terminal Pins) to the AMT303-V, eliminating interface modifications. The programmable PPR capability provides operational flexibility while supporting fixed 200 PPR configuration. Product status is Active, ensuring long-term availability and supply chain stability. ROHS3 compliance exceeds the original RoHS Compliant specification.

AMT313S-V serves as an alternative substitute where connector-based termination is acceptable or preferred. This part requires interface adaptation due to Connector termination versus Terminal Pins on the original part. Connector termination may offer advantages in applications requiring frequent connection/disconnection cycles. Product status is Active with equivalent ROHS3 compliance and REACH status.

Both substitutes maintain all critical electrical and mechanical parameters: 5V supply voltage, incremental encoder type, commutation output, 2mm–8mm open center actuator compatibility, right-angle orientation, and chassis mount capability.

Frequently Asked Questions (FAQ)

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

A: Both parts are functionally compatible with the AMT303-V when configured to 200 PPR operation. The primary difference is termination style: AMT313Q-V uses Terminal Pins (matching the original), while AMT313S-V uses Connector termination. Selection depends on circuit board design and connector availability.

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

A: The AMT313Q-V and AMT313S-V feature programmable pulses per revolution, allowing configuration to 200 PPR to match the fixed 200 PPR specification of the AMT303-V. This programmability provides design flexibility for future applications without requiring different part numbers.

Q: Are there termination compatibility considerations?

A: Yes. The AMT303-V uses Terminal Pins termination. AMT313Q-V maintains this termination style for direct board-level replacement. AMT313S-V uses Connector termination, requiring either connector installation on the circuit board or a mating connector assembly for integration.

Q: How do RoHS compliance levels affect substitution?

A: The AMT303-V is RoHS Compliant. Both substitutes are ROHS3 Compliant, which represents an enhanced compliance standard. ROHS3 compliance is fully compatible with systems designed for RoHS Compliant components.

Q: Why is the AMT303-V classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The identified substitutes (AMT313Q-V and AMT313S-V) are Active products, ensuring continued availability for new designs and system support.

Q: Are moisture sensitivity levels identical across all three parts?

A: Yes. All three parts specify Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or operation.
