AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 500 pulses per revolution with commutation output in counter-clockwise (CCW) orientation. This encoder features a right-angle chassis mount design with a 2mm to 8mm open center actuator and operates at 5V supply voltage. The product is classified as obsolete, necessitating identification of active alternative models that maintain functional and mechanical compatibility for continued system integration.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Must remain incremental
• Supply Voltage: Must operate at 5V
• Mounting Configuration: Chassis mount with right-angle orientation required
• Actuator Compatibility: 2mm to 8mm open center actuator interface
• Termination Interface: Physical connection method (terminal pins vs. connector)
• Output Characteristics: Commutation output with matching pole configuration
• Regulatory Compliance: RoHS and REACH status alignment

The substitute parts AMT313Q-V and AMT313S-V are qualified alternatives based on matching encoder type, supply voltage, mounting type, orientation, actuator type, and regulatory compliance. Both substitutes feature programmable pulses per revolution, enabling configuration to the original 500 PPR specification. The primary distinction between substitutes is termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing support, addressing the obsolescence status of the AMT303-V. Selection between the two substitutes is determined by termination interface requirements:

AMT313Q-V is the direct functional equivalent when terminal pin termination is required. This part maintains identical electrical interface characteristics to the original AMT303-V and is suitable for direct integration into existing PCB designs or harness assemblies utilizing terminal pin connections.

AMT313S-V is the appropriate selection when connector-based termination is preferred or required by system design. The connector interface provides enhanced mechanical robustness and simplified field replacement capabilities compared to terminal pin termination.

Both substitutes carry ROHS3 compliance, representing an advancement over the original RoHS Compliant designation. Both maintain REACH Unaffected status and identical regulatory classification (ECCN: EAR99, HTSUS: 8543.70.4500). The programmable pulses per revolution feature of both substitutes enables configuration to match the original 500 PPR specification, ensuring signal compatibility with downstream signal processing circuits.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to output 500 pulses per revolution like the original AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution capability, allowing configuration to 500 PPR to match the original encoder specification.

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

A: The termination interface differs. AMT313Q-V uses terminal pins, matching the original AMT303-V configuration. AMT313S-V uses a connector interface. All other electrical and mechanical parameters are identical.

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

A: Yes. Both substitutes maintain identical mounting type (chassis mount, motors), orientation (right angle), and actuator type (2mm to 8mm open center), ensuring mechanical compatibility with existing installations.

Q: Do the substitute parts require different supply voltage?

A: No. Both AMT313Q-V and AMT313S-V operate at 5V supply voltage, identical to the original AMT303-V.

Q: What is the advantage of ROHS3 compliance over RoHS Compliant?

A: ROHS3 represents the current regulatory standard for restriction of hazardous substances in electrical and electronic equipment. Both designations indicate compliance with hazardous substance restrictions; ROHS3 reflects the current regulatory framework.

Q: Can either substitute part be used as a direct drop-in replacement without circuit modification?

A: AMT313Q-V is suitable for direct replacement in applications using terminal pin termination. AMT313S-V requires connector interface compatibility in the receiving circuit. Both require configuration of the programmable pulses per revolution parameter to 500 PPR.

Q: Are there inventory considerations for selecting between the two substitutes?

A: Both parts are in active production with substantial inventory availability (AMT313Q-V: 1349 units; AMT313S-V: 1045 units), ensuring supply continuity for new designs and replacement applications.
