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 orientation. This component is designed for chassis mount and motor applications with a 5V supply voltage and open center actuator configuration (2mm ~ 8mm).

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for new designs or replacement applications where the original part is no longer in production.

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 compatibility:

• Encoder Type: Incremental
• Output Type: Commutation
• Voltage - Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle

The AMT313Q-V and AMT313S-V both meet these core compatibility criteria. The primary distinction between these substitutes and the original part is the pulses per revolution specification: the AMT303-V provides a fixed 1024 PPR, while the substitute parts feature programmable PPR capability. Both substitute parts are in active production status, ensuring long-term availability.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active production alternatives to the obsolete AMT303-V. Selection between these two substitutes depends on termination requirements:

The AMT313Q-V maintains terminal pin termination, matching the original AMT303-V configuration. This option provides direct compatibility with existing connector designs and PCB layouts.

The AMT313S-V features connector termination, which may require interface modifications depending on the application's existing wiring infrastructure.

Both substitutes carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The programmable PPR capability of both substitutes provides design flexibility beyond the fixed 1024 PPR specification of the original part.

Frequently Asked Questions (FAQ)

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

A: Both parts share the same core electrical and mechanical specifications: incremental encoder type, commutation output, 5V supply, open center actuator, right-angle orientation, and chassis mount configuration. The primary difference is termination style. AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface.

Q: What is the significance of programmable PPR in the substitute parts?

A: The AMT303-V provides a fixed 1024 PPR output. The AMT313Q-V and AMT313S-V offer programmable PPR capability, allowing configuration to 1024 PPR or other supported values. This flexibility enables the substitutes to serve multiple applications without requiring different part numbers.

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

A: The AMT303-V is RoHS Compliant. Both substitutes are ROHS3 Compliant, representing a more recent regulatory standard. All three parts are REACH Unaffected and carry the same moisture sensitivity level (MSL 1 - Unlimited).

Q: Which substitute should be selected for direct replacement?

A: For applications requiring minimal design changes, the AMT313Q-V is the preferred substitute due to its terminal pin termination matching the original AMT303-V configuration.

Q: What is the availability status of these substitutes?

A: The AMT313Q-V and AMT313S-V are both in active production, ensuring long-term component availability and supply chain continuity.
