AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 250 pulses per revolution with commutation output in a right-angle chassis mount orientation. This encoder operates at 5V supply voltage and features an open center actuator design with terminal pin termination.

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring incremental encoder functionality with fixed 250 PPR output specifications.

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:

• Manufacturer: CUI Devices (same manufacturer ecosystem)
• Encoder Type: Incremental
• Output Type: Commutation
• Voltage - Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle

Substitution Logic: The AMT313Q-V and AMT313S-V are qualified substitutes because they maintain identical specifications across all critical mechanical and electrical parameters. Both substitute parts feature programmable pulses per revolution capability, which provides functional equivalence to the fixed 250 PPR configuration of the AMT303-V. The primary distinction between substitutes is termination style: the AMT313Q-V retains terminal pin termination (matching the original), while the AMT313S-V uses connector termination.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V Selection: The AMT313Q-V is the primary substitute for direct replacement applications. It maintains terminal pin termination identical to the AMT303-V, ensuring compatibility with existing PCB layouts and connector designs. The part is currently in active production status with 1349 units in stock. Programmable PPR capability allows configuration to the original 250 PPR specification. ROHS3 compliance exceeds the original RoHS requirement.

AMT313S-V Selection: The AMT313S-V is suitable for applications where connector termination is acceptable or preferred. This variant provides the same electrical and mechanical specifications as the AMT313Q-V but uses a connector interface instead of terminal pins. Selection of this part requires confirmation that the connector type is compatible with the application's interface requirements. The part is in active production with 1045 units in stock.

Compliance Considerations: Both substitute parts maintain REACH Unaffected status and EAR99 ECCN classification, consistent with the original part. ROHS3 compliance of substitute parts provides enhanced regulatory alignment compared to the original RoHS Compliant designation.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V or AMT313S-V be used as direct replacements for the AMT303-V?

A: Yes, both parts are functionally equivalent substitutes. The AMT313Q-V is the preferred choice for applications requiring terminal pin termination. The AMT313S-V is suitable where connector termination is compatible with the application design.

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

A: The primary difference is termination style. The AMT313Q-V uses terminal pins (matching the original AMT303-V), while the AMT313S-V uses connector termination. All other electrical and mechanical specifications are identical.

Q: How does the programmable PPR feature of the substitutes affect compatibility?

A: The programmable PPR capability of both substitute parts allows configuration to match the original 250 PPR specification of the AMT303-V. This provides functional equivalence and flexibility for future application adjustments.

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

A: Both substitute parts maintain REACH Unaffected and EAR99 ECCN status. The substitutes feature ROHS3 compliance, which exceeds the original RoHS Compliant designation, providing enhanced regulatory alignment.

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

A: The AMT313Q-V has 1349 units in stock, and the AMT313S-V has 1045 units in stock. Both are classified as active products in current production.
