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 features a right-angle orientation, 6-pole commutation output, and operates at 5V supply voltage. The encoder is designed for chassis mount and motor applications with an open center actuator accepting shaft sizes from 2mm to 8mm.

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Incremental
• Supply Voltage: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Orientation: Right Angle
• Mounting Type: Chassis Mount, Motors
• Output Type: Commutation
• Detent: No
• Built-in Switch: No

The AMT313Q-V and AMT313S-V meet these core compatibility criteria. Both substitute parts feature programmable pulses per revolution, which provides functional equivalence to the fixed 1000 PPR specification of the AMT303-V when configured appropriately. Both substitutes are active products with current manufacturing status, addressing the obsolescence of the original part.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing support, providing supply chain continuity for the obsolete AMT303-V.

AMT313Q-V maintains terminal pin termination identical to the original AMT303-V, supporting direct integration into existing PCB designs without connector modifications.

AMT313S-V features connector-based termination, requiring mechanical interface adaptation but offering standardized connector compatibility for modular system designs.

Both substitutes carry ROHS3 compliance, exceeding the RoHS compliance level of the original part. All three encoders share identical electrical supply requirements, mechanical mounting specifications, and environmental ratings.

Frequently Asked Questions (FAQ)

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

A: Yes. Both substitute parts feature programmable pulses per revolution. Configuration to 1000 PPR aligns the output specification with the original AMT303-V.

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

A: The termination style differs. AMT313Q-V uses terminal pins; AMT313S-V uses a connector interface. This affects mechanical integration but does not impact electrical performance or functional compatibility.

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

A: Yes. Both substitutes share identical actuator type, orientation, and mounting specifications with the original part.

Q: Do the substitute parts meet current regulatory compliance standards?

A: Yes. Both AMT313Q-V and AMT313S-V carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Q: What supply voltage do the substitute encoders require?

A: Both AMT313Q-V and AMT313S-V operate at 5V supply voltage, matching the original AMT303-V specification.
