AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 1024 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

Substitution eligibility for the AMT303-V is determined by strict alignment of the following critical parameters:

• Encoder Type: Must be Incremental
• Voltage Supply: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Output Type: Must support Commutation output
• Detent: Must be No
• Built-in Switch: Must be No
• Moisture Sensitivity Level: Must be 1 (Unlimited)
• REACH Status: Must be REACH Unaffected

The substitute parts AMT313Q-V and AMT313S-V satisfy all mandatory electrical and mechanical parameters. Both are active products from CUI Devices' AMT31 series with programmable pulse-per-revolution capability, providing functional equivalence while offering enhanced flexibility over the fixed 1024 PPR specification of the obsolete AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are qualified substitutes for the obsolete AMT303-V based on electrical and mechanical parameter alignment. Selection between the two substitute options depends on termination interface requirements:

AMT313Q-V maintains terminal pin termination identical to the original AMT303-V, enabling direct mechanical and electrical integration with existing connector designs and PCB layouts.

AMT313S-V provides connector-based termination, requiring interface adapter consideration but offering standardized connector compatibility for new system designs.

Both substitute parts carry active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The programmable pulse-per-revolution capability of both substitutes provides operational flexibility beyond the fixed 1024 PPR specification of the AMT303-V.

Frequently Asked Questions (FAQ)

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

A: Both parts satisfy all mandatory electrical and mechanical parameters. Selection depends on termination interface compatibility. AMT313Q-V uses terminal pins matching the original design; AMT313S-V uses a connector interface requiring adapter evaluation.

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

A: The primary difference is termination style. AMT313Q-V provides terminal pins; AMT313S-V provides connector termination. All other electrical and mechanical specifications are equivalent.

Q: Does the programmable PPR feature of the substitutes affect compatibility?

A: The programmable capability provides operational flexibility. Systems configured for 1024 PPR operation can be maintained with either substitute by programming to the original specification.

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

A: The AMT303-V is RoHS Compliant; both substitutes are ROHS3 Compliant, representing enhanced regulatory alignment. All three parts maintain REACH Unaffected status.

Q: What inventory status should be considered for procurement?

A: AMT303-V is obsolete with 726 units in stock. AMT313Q-V has 1349 units available; AMT313S-V has 1045 units available. Both substitutes are active products with established supply chains.
