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 8-pole commutation output in a right-angle orientation. This component is designed for chassis mount and motor applications requiring precise rotational feedback at 5V supply voltage.

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this encoder specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on matching the following critical parameters:

• Encoder Type: Incremental
• Output Type: Commutation
• Voltage - Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Detent: No
• Built in Switch: No
• RoHS and REACH Compliance: Maintained

The AMT313Q-V and AMT313S-V are qualified substitutes because they maintain all core mechanical and electrical compatibility parameters. The primary difference is that substitute parts feature programmable pulses per revolution, whereas the AMT303-V is fixed at 250 PPR. Both substitutes are active products with current manufacturing status, addressing the obsolescence of the original part.

Parameter Comparison

Engineering Selection Recommendations

The AMT303-V is obsolete and no longer in active production. Both AMT313Q-V and AMT313S-V are active products from the same manufacturer, ensuring continued supply chain availability and compliance with current RoHS3 standards.

Selection between the two substitutes depends on termination requirements: the AMT313Q-V maintains terminal pin termination matching the original AMT303-V, while the AMT313S-V uses connector termination. For applications requiring direct pin-to-pin compatibility without connector interface modifications, the AMT313Q-V is the preferred substitute.

Both substitutes support programmable pulse per revolution configuration, allowing the system to be set to 250 PPR to match the original AMT303-V fixed specification.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V directly replace AMT303-V without circuit modifications?

A: Both parts maintain identical electrical supply voltage (5V), output type (commutation), mounting configuration (chassis mount, right angle), and actuator specifications (2mm ~ 8mm open center). The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses connector termination. Direct replacement without modification is possible with AMT313Q-V. AMT313S-V requires connector interface adaptation.

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

A: The AMT303-V is fixed at 250 PPR. The AMT313Q-V and AMT313S-V feature programmable PPR, allowing configuration to 250 PPR to match the original specification. This programmability provides flexibility for future design iterations without requiring component changes.

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

A: The AMT303-V is RoHS Compliant. Both substitutes are ROHS3 Compliant, representing a more recent and stringent compliance standard. Both maintain REACH Unaffected status and MSL 1 (Unlimited) rating, ensuring equivalent environmental and handling requirements.

Q: Which substitute should be selected for new production designs?

A: For new production, either AMT313Q-V or AMT313S-V is appropriate based on termination interface requirements. Both are active products with established supply chains. The AMT313Q-V is recommended for designs requiring terminal pin termination to minimize interface modifications.
