AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 200 pulses per revolution with commutation output in counter-clockwise direction. The device features a 10-pole right-angle orientation and operates at 5V supply voltage. This part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional and mechanical compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is determined by the following critical parameters that must remain consistent across alternative components:

• Encoder Type: Incremental operation required
• Voltage Supply: 5V operation mandatory
• Actuator Type: 2mm ~ 8mm open center configuration
• Mounting Type: Chassis mount and motor mounting compatibility
• Orientation: Right-angle form factor
• Output Type: Commutation output with CCW, 10-pole configuration
• Termination Style: Connection method compatibility

The substitute parts AMT313Q-V and AMT313S-V are identified as functional equivalents. Both maintain the core electrical and mechanical specifications of the original AMT303-V while offering programmable pulses-per-revolution capability, providing design flexibility for applications requiring variable resolution. Both substitutes are active products with current manufacturing status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V serve as direct functional replacements for the obsolete AMT303-V. Selection between these two substitutes is determined by termination requirements:

AMT313Q-V features terminal pin termination, maintaining the same connection method as the original AMT303-V. This option provides direct mechanical and electrical compatibility with existing PCB layouts and connector designs.

AMT313S-V features connector termination, offering an alternative connection interface. This configuration may require connector adaptation depending on the application's existing infrastructure.

Both substitutes carry ROHS3 compliance certification, representing an advancement over the original RoHS compliance status of the AMT303-V. Both maintain REACH unaffected status and identical moisture sensitivity ratings. The programmable pulses-per-revolution capability of both substitutes provides additional design flexibility compared to the fixed 200 PPR specification of the original part, allowing single-component solutions across multiple resolution requirements.

Frequently Asked Questions (FAQ)

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

A: Both parts maintain electrical and mechanical compatibility with the AMT303-V across all critical parameters: 5V supply voltage, incremental encoder type, commutation output, right-angle orientation, 2mm ~ 8mm open center actuator, and chassis mount configuration. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses connector termination.

Q: What is the difference between fixed 200 PPR and programmable PPR?

A: The AMT303-V provides fixed 200 pulses per revolution output. The AMT313Q-V and AMT313S-V offer programmable resolution, allowing configuration to 200 PPR or alternative resolutions as required by the application. This programmability does not affect compatibility with systems designed for 200 PPR operation.

Q: Are there termination compatibility considerations?

A: Yes. The AMT313Q-V maintains terminal pin termination identical to the AMT303-V, requiring no interface modifications. The AMT313S-V uses connector termination and requires appropriate connector adaptation for integration into existing systems designed for the AMT303-V.

Q: What compliance improvements do the substitute parts offer?

A: Both AMT313Q-V and AMT313S-V carry ROHS3 certification, representing enhanced compliance compared to the RoHS compliance of the original AMT303-V. Both maintain REACH unaffected status and identical moisture sensitivity ratings (MSL 1, Unlimited).

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

A: The AMT303-V is no longer in active production. The AMT313 series represents the current active product line from CUI Devices for this encoder category, offering equivalent functionality with enhanced compliance certifications and programmable resolution options.
