AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 192 pulses per revolution with commutation output in a right-angle chassis mount configuration. This encoder is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The part operates at 5V supply voltage with an open center actuator design and terminal pin termination.

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
• RoHS and REACH Compliance Status

The AMT313Q-V and AMT313S-V both satisfy these core electrical and mechanical requirements. The primary distinction between these substitutes is the pulses per revolution specification: while the original AMT303-V is fixed at 192 PPR, the substitute parts feature programmable PPR capability, allowing configuration flexibility for system integration. Both substitutes maintain active product status and full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are valid substitutes for the obsolete AMT303-V based on electrical and mechanical parameter alignment. The primary selection criterion between these two substitutes is termination style:

• AMT313Q-V: Terminal Pins termination, packaged in Box format
• AMT313S-V: Connector termination, packaged in Box format

Selection should be based on the existing system's connector interface requirements. Both parts maintain active product status and current compliance certifications (ROHS3 and REACH Unaffected), ensuring long-term availability and regulatory alignment. The programmable PPR feature in both substitutes provides additional system flexibility compared to the fixed 192 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 are functionally compatible substitutes based on core electrical and mechanical parameters. The key difference is termination style: AMT313Q-V uses terminal pins while AMT313S-V uses a connector. Selection depends on your system's interface requirements.

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

A: The AMT303-V operates at a fixed 192 PPR, while AMT313Q-V and AMT313S-V feature programmable PPR capability. This allows configuration to match your system's resolution requirements without changing the physical component.

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

A: The original AMT303-V is RoHS Compliant, while substitutes are ROHS3 Compliant, representing a more recent regulatory standard. Both maintain REACH Unaffected status. The substitutes meet current compliance requirements.

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

A: Obsolete status indicates the part is no longer in active production. The AMT313 series represents the current active product line from CUI Devices for this encoder category, offering enhanced features such as programmable PPR.

Q: What packaging formats are available for the substitute parts?

A: Both AMT313Q-V and AMT313S-V are supplied in Box packaging format, consistent with standard component distribution practices.
