AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 96 pulses per revolution (PPR) and 6-pole commutation output. This component is designed for chassis mount and motor applications with a right-angle orientation and open center actuator (2mm–8mm). The AMT303-V operates at 5V supply voltage with terminal pin termination.

The AMT303-V is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Incremental (all substitutes match)
• Output Type: Commutation with 6-pole configuration (all substitutes match)
• Supply Voltage: 5V (all substitutes match)
• Actuator Type: 2mm–8mm Open Center (all substitutes match)
• Mounting Type: Chassis Mount, Motors (all substitutes match)
• Orientation: Right Angle (all substitutes match)
• Termination Style: Terminal Pins or Connector (substitutes vary)

The primary distinction among substitutes is the Pulses per Revolution specification. The AMT303-V provides a fixed 96 PPR output, while substitute models AMT313Q-V and AMT313S-V feature programmable PPR capability, allowing configuration to match the original 96 PPR specification or other required values. Both substitutes are active products with current manufacturing status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are suitable substitutes for the obsolete AMT303-V based on the following engineering criteria:

Product Status: Both substitutes are active products with current manufacturing support, ensuring long-term availability and supply chain continuity compared to the obsolete AMT303-V.

Compliance Certifications: Both substitutes meet ROHS3 compliance and REACH unaffected status, providing improved regulatory alignment over the original RoHS Compliant designation of the AMT303-V.

Functional Compatibility: Both substitutes maintain identical electrical and mechanical specifications across supply voltage, actuator type, mounting configuration, and orientation. The programmable PPR feature allows configuration to the original 96 PPR specification or alternative values as required by system design.

Termination Consideration: AMT313Q-V retains terminal pin termination matching the AMT303-V. AMT313S-V uses connector termination, which may require interface adaptation depending on existing circuit board design.

Selection between AMT313Q-V and AMT313S-V depends on termination style compatibility with the target application. Both parts are electrically and mechanically interchangeable when PPR is configured appropriately.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 96 PPR output of the AMT303-V?

A: Yes. Both substitute parts feature programmable PPR capability, allowing configuration to 96 PPR or other specified values to match system requirements.

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 connector termination. Electrical and mechanical specifications are otherwise identical.

Q: Are the substitute parts pin-compatible with the AMT303-V?

A: AMT313Q-V maintains terminal pin termination and is mechanically compatible. AMT313S-V uses connector termination and requires interface adaptation. Verify connector specifications against your circuit board design before selection.

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

A: The AMT303-V is no longer in active production. Substitute models AMT313Q-V and AMT313S-V provide equivalent functionality with programmable PPR capability and improved compliance certifications.

Q: Do the substitute parts require firmware or software configuration?

A: The programmable PPR feature requires configuration to the desired pulse count. Consult CUI Devices technical documentation for configuration procedures specific to your application.

Q: Are moisture sensitivity levels identical across all three parts?

A: Yes. All three parts (AMT303-V, AMT313Q-V, and AMT313S-V) have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.
