AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 250 pulses per revolution with commutation output in counter-clockwise direction and 4-pole right-angle orientation. This encoder is designed for chassis mount and motor applications with a 5V supply requirement and open center actuator (2mm–8mm range).

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications currently utilizing this encoder model.

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 (maintained across all substitutes)
• Output Type: Commutation output (maintained across all substitutes)
• Voltage Supply: 5V (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: Differs between substitutes (Terminal Pins vs. Connector)

The primary distinction between the AMT303-V and its substitutes is the pulses per revolution specification. The AMT303-V operates at a fixed 250 PPR, while the substitute models (AMT313Q-V and AMT313S-V) feature programmable PPR capability, allowing configuration to match the original 250 PPR specification when required.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V: This substitute maintains terminal pin termination identical to the AMT303-V, providing direct mechanical and electrical compatibility at the connection interface. The AMT313Q-V is currently in active production status and carries ROHS3 compliance certification, exceeding the RoHS compliance level of the obsolete AMT303-V. The programmable PPR capability allows configuration to the original 250 PPR specification.

AMT313S-V: This substitute features connector-based termination, which differs from the AMT303-V terminal pin configuration. Selection of this model requires accommodation for the alternative termination interface. The AMT313S-V is in active production status with ROHS3 compliance certification. Like the AMT313Q-V, programmable PPR functionality enables configuration to match the original 250 PPR setting.

Both substitutes are manufactured by CUI Devices and maintain all critical functional parameters: incremental encoder type, commutation output, 5V supply voltage, open center actuator range, chassis mount orientation, and right-angle mechanical configuration.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V and AMT313S-V be directly substituted for the AMT303-V?

A: Both models maintain the core functional parameters required for substitution: incremental encoder type, commutation output, 5V supply, 2mm–8mm open center actuator, chassis mount orientation, and right-angle configuration. The primary difference is termination style. The AMT313Q-V uses terminal pins (matching the AMT303-V), while the AMT313S-V uses a connector interface. Selection depends on your application's termination requirements.

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

A: The AMT303-V operates at a fixed 250 PPR. The AMT313Q-V and AMT313S-V feature programmable PPR, allowing configuration to 250 PPR or other values as needed. This flexibility enables a single substitute model to replace multiple fixed-PPR variants.

Q: Are there compliance differences between the AMT303-V and its substitutes?

A: The AMT303-V carries RoHS Compliant certification. Both substitute models (AMT313Q-V and AMT313S-V) carry ROHS3 Compliant certification, which represents a more current compliance standard. All three models are REACH Unaffected and carry identical moisture sensitivity levels (MSL 1 – Unlimited).

Q: Which substitute should I select if my application uses terminal pin connections?

A: The AMT313Q-V maintains terminal pin termination, providing direct compatibility with existing wiring and connector interfaces designed for the AMT303-V.

Q: Which substitute should I select if my application uses connector-based termination?

A: The AMT313S-V features connector-based termination and is appropriate for applications requiring this interface type.

Q: What is the inventory status of these parts?

A: The AMT303-V (obsolete) has 778 pieces in stock. The AMT313Q-V (active) has 1349 pieces in stock. The AMT313S-V (active) has 1045 pieces in stock.
