AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 1000 pulses per revolution (PPR) output. This component is designed for chassis mount and motor applications with a right-angle orientation and 5V supply voltage. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Incremental (required match)
• Voltage Supply: 5V (required match)
• Mounting Type: Chassis Mount, Motors (required match)
• Orientation: Right Angle (required match)
• Actuator Type: 2mm ~ 8mm Open Center (required match)
• Output Type: Commutation (required match)
• Pulses per Revolution: 1000 fixed or programmable to 1000 (functional equivalence)
• Termination Style: Terminal Pins or Connector (mechanical interface variation)

The substitute parts AMT313Q-V and AMT313S-V maintain all critical electrical and mechanical parameters. Both feature programmable PPR capability, allowing configuration to 1000 PPR to match the fixed output of the AMT303-V. The primary differences are termination style and product status (active vs. obsolete).

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for direct replacement applications. This part maintains terminal pin termination identical to the AMT303-V, ensuring compatibility with existing connector interfaces. The programmable PPR feature allows configuration to 1000 PPR, matching the fixed output specification of the obsolete part. Active product status ensures ongoing availability and supply chain continuity. ROHS3 compliance exceeds the RoHS compliance of the original part.

AMT313S-V serves as an alternative substitute when connector-based termination is acceptable or preferred in system redesign. This part provides identical electrical and mechanical functionality with the added benefit of connector termination, which may simplify assembly and maintenance procedures. Active product status and ROHS3 compliance apply equally to this option.

Both substitute parts are manufactured by CUI Devices, maintaining consistency with the original equipment ecosystem. Selection between AMT313Q-V and AMT313S-V depends on termination interface requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to output exactly 1000 PPR like the AMT303-V?

A: Yes. Both substitute parts feature programmable PPR capability, allowing configuration to 1000 PPR through appropriate programming procedures to match the fixed output of the AMT303-V.

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

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

Q: Are the substitute parts compatible with existing AMT303-V mounting locations?

A: Yes. Both AMT313Q-V and AMT313S-V maintain identical mounting type (Chassis Mount, Motors), orientation (Right Angle), and actuator type (2mm ~ 8mm Open Center) specifications, ensuring mechanical compatibility with existing installations.

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

A: No. The programmable capability is a functional enhancement that allows configuration flexibility. When programmed to 1000 PPR, the output is functionally equivalent to the fixed 1000 PPR specification of the AMT303-V.

Q: What compliance advantages do the substitute parts offer?

A: Both AMT313Q-V and AMT313S-V meet ROHS3 compliance, which represents a higher standard than the RoHS compliance of the obsolete AMT303-V. Both maintain identical moisture sensitivity level (1 - Unlimited) and REACH unaffected status.

Q: Which substitute should be selected for new designs?

A: For new designs, either substitute is acceptable based on termination interface requirements. AMT313Q-V is recommended for direct replacement scenarios requiring terminal pin termination. AMT313S-V is recommended when connector-based termination provides system design advantages.
