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 encoder features a right-angle orientation, chassis mount configuration, and terminal pin termination, operating at 5V supply voltage. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations where this specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Incremental (maintained across all substitutes)
• Supply Voltage: 5V (consistent requirement)
• Actuator Type: 2mm ~ 8mm Open Center (mechanical compatibility)
• Mounting Type: Chassis Mount, Motors (installation compatibility)
• Orientation: Right Angle (form factor requirement)
• Output Type: Commutation (signal output compatibility)
• Manufacturer: CUI Devices (same manufacturer ecosystem)

The substitute parts AMT313Q-V and AMT313S-V maintain these core parameters. Both feature programmable pulses per revolution, allowing configuration to match the 200 PPR specification of the original AMT303-V. The primary differences lie in termination style (Terminal Pins vs. Connector) 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 designs. The AMT313Q-V holds Active product status with ROHS3 compliance, providing long-term availability and regulatory alignment. Programmable PPR capability allows configuration to the required 200 PPR specification.

AMT313S-V serves as an alternative substitute where connector-based termination is acceptable or preferred. This part also maintains Active status and ROHS3 compliance. The connector termination style may require interface modifications compared to the terminal pin configuration of the original AMT303-V.

Both substitutes share identical electrical specifications, mechanical mounting characteristics, and environmental compliance ratings with the AMT303-V. Selection between AMT313Q-V and AMT313S-V depends on termination style compatibility with the target application.

Frequently Asked Questions (FAQ)

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

A: Yes. Both substitute parts feature programmable pulses per revolution, 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: The termination style differs. AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface. Both maintain identical electrical and mechanical parameters.

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

A: Yes. Both AMT313Q-V and AMT313S-V maintain the same chassis mount, right-angle orientation, and 2mm ~ 8mm open center actuator type as the AMT303-V.

Q: What compliance certifications apply to the substitute parts?

A: Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original AMT303-V is RoHS compliant.

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

A: The AMT303-V has been discontinued by the manufacturer. The AMT313 series (AMT313Q-V and AMT313S-V) represent the current active product line offering equivalent functionality with programmable configuration options.

Q: Are there any electrical parameter differences between the three encoders?

A: No. All three encoders operate at 5V supply voltage, feature incremental encoding with commutation output, and share identical actuator and mounting specifications. The key difference is PPR configurability in the substitute parts.
