AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 96 pulses per revolution with commutation output in counter-clockwise (CCW) configuration. This component is designed for chassis mount and motor applications with a right-angle orientation and 5V supply voltage. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Incremental (maintained across all substitutes)
• Output Type: Commutation output configuration
• Voltage Supply: 5V operation (maintained across all substitutes)
• Actuator Type: 2mm ~ 8mm Open Center (maintained across all substitutes)
• Mounting Type: Chassis Mount, Motors (maintained across all substitutes)
• Orientation: Right Angle (maintained across all substitutes)
• Termination Style: Terminal Pins or Connector variants acceptable

The AMT313Q-V and AMT313S-V are qualified substitutes because they maintain the core electrical and mechanical parameters. The key distinction is that substitute parts feature programmable pulses per revolution, allowing configuration to match the original 96 PPR specification or other requirements. Both substitutes are active products with current manufacturing status, addressing the obsolescence of the original AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for direct replacement applications. This component maintains terminal pin termination identical to the original AMT303-V, ensuring compatibility with existing connector designs and PCB layouts. The programmable pulses per revolution feature allows configuration to the original 96 PPR specification. The part is in active production status with ROHS3 compliance, providing long-term supply assurance and regulatory alignment.

AMT313S-V serves as an alternative substitute for applications where connector-based termination is acceptable or preferred. This variant offers the same electrical and mechanical compatibility as the AMT313Q-V but utilizes a connector termination style instead of terminal pins. Selection of this variant requires verification that the connector interface is compatible with the target application.

Both substitutes satisfy the core functional requirements: incremental encoding, commutation output, 5V operation, right-angle orientation, and chassis mount capability. The active product status of both alternatives ensures availability and ongoing manufacturer support, addressing the obsolescence constraint of the original AMT303-V.

Frequently Asked Questions (FAQ)

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

A: Both are functionally equivalent substitutes for the AMT303-V in terms of electrical operation and mechanical mounting. The primary difference is termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector. Selection depends on your application's termination requirements.

Q: What is the significance of programmable pulses per revolution in the substitute parts?

A: The AMT313Q-V and AMT313S-V feature programmable PPR, allowing configuration to match the original 96 PPR specification or other values as needed. This flexibility provides additional design options beyond the fixed 96 PPR of the AMT303-V.

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

A: The original AMT303-V is RoHS Compliant, while both substitutes are ROHS3 Compliant, representing an updated compliance standard. Both maintain REACH Unaffected status. All three parts have MSL 1 (Unlimited) rating.

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

A: Obsolete status indicates the manufacturer has discontinued production. The AMT313Q-V and AMT313S-V are active products, ensuring continued availability for new designs and replacements.

Q: Which substitute should I select for a new design?

A: For new designs, either substitute is acceptable based on your termination preference. AMT313Q-V is recommended if terminal pin compatibility is required; AMT313S-V is suitable if connector-based termination is acceptable or preferred.
