AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 200 pulses per revolution with commutation output in a right-angle chassis mount configuration. This encoder is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

The AMT303-V operates at 5V supply voltage with an open center actuator design (2mm to 8mm range) and terminal pin termination. Its obsolete status necessitates evaluation of active substitute models that maintain electrical and mechanical compatibility with existing applications.

Key Parameters

Substitute Part Grouping Explanation

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

Core Compatibility Parameters:

• Encoder Type: Incremental
• 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 (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitution Logic:

The AMT303-V specifies a fixed 200 pulses per revolution output. Substitute models AMT313Q-V and AMT313S-V feature programmable pulse per revolution capability, allowing configuration to match the original 200 PPR specification. Both substitutes maintain identical supply voltage, actuator geometry, mounting configuration, and orientation as the original part.

The primary distinction between substitutes is termination style: AMT313Q-V retains terminal pin termination (matching AMT303-V), while AMT313S-V uses connector termination. Both substitutes are active products with current manufacturing status, addressing the obsolescence of the original AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V Selection Criteria:

The AMT313Q-V is the preferred substitute when direct termination compatibility is required. This part maintains terminal pin termination identical to the AMT303-V, minimizing integration modifications. The programmable pulses per revolution feature allows configuration to the original 200 PPR specification. Active product status ensures ongoing availability and manufacturing support. ROHS3 compliance exceeds the original RoHS Compliant designation, meeting current regulatory requirements.

AMT313S-V Selection Criteria:

The AMT313S-V serves as an alternative when connector-based termination is acceptable or preferred in system redesign. This configuration may reduce assembly complexity in applications where connector interfaces are standard. Like the AMT313Q-V, programmable PPR capability accommodates the 200 PPR requirement. Active product status and ROHS3 compliance provide equivalent regulatory and supply chain advantages.

Compliance Considerations:

Both substitute parts exceed the original RoHS compliance level (ROHS3 vs. RoHS Compliant) and maintain REACH Unaffected status. Moisture sensitivity level remains unchanged at MSL 1 (Unlimited), preserving handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the AMT303-V's 200 PPR output?

A: Yes. Both substitute parts feature programmable pulses per revolution capability, allowing configuration to 200 PPR to match the original AMT303-V specification.

Q: What is the primary difference between AMT313Q-V and AMT313S-V?

A: Termination style differs. The AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses connector termination. All other electrical and mechanical parameters are identical.

Q: Is the AMT313Q-V a direct replacement for the AMT303-V?

A: The AMT313Q-V maintains identical termination style, supply voltage, actuator geometry, mounting configuration, and orientation. Programmable PPR capability requires configuration to 200 PPR. No physical modifications to mounting or electrical connections are necessary.

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

A: Product status reflects CUI Devices' manufacturing discontinuation. Substitute models AMT313Q-V and AMT313S-V provide equivalent functionality with active production status.

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

A: Both substitutes meet or exceed original compliance levels. ROHS3 compliance is more stringent than the original RoHS Compliant designation. REACH Unaffected status remains unchanged.

Q: Which substitute should be selected for new designs?

A: Selection depends on termination requirements. For terminal pin compatibility, use AMT313Q-V. For connector-based integration, use AMT313S-V. Both are active products with equivalent electrical performance.
