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 a right-angle chassis mount configuration. This encoder is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

The AMT303-V operates at 5V supply voltage with an open center actuator design (2mm to 8mm range) and terminal pin termination. Its obsolete status necessitates evaluation of active alternative models that maintain electrical and mechanical compatibility with existing applications.

Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• 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
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: Required

Variable Parameter:

• Pulses per Revolution: The AMT303-V specifies 96 PPR; substitute parts with programmable PPR capability maintain compatibility through configuration to 96 PPR operation.

The identified substitutes (AMT313Q-V and AMT313S-V) maintain all critical electrical and mechanical parameters while offering programmable pulse-per-revolution functionality and active product status.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with ROHS3 compliance, providing long-term availability advantages over the obsolete AMT303-V.

AMT313Q-V Selection: Maintains terminal pin termination identical to the AMT303-V, minimizing integration changes. Programmable PPR capability allows configuration to 96 PPR operation, matching original specifications.

AMT313S-V Selection: Offers connector-based termination, which differs from the AMT303-V terminal pin design. This substitution requires interface modification but provides connector-based reliability benefits. Programmable PPR capability supports 96 PPR configuration.

Both substitutes maintain full electrical and mechanical compatibility across all critical parameters: 5V supply voltage, commutation output, open center actuator range, right-angle orientation, and chassis mount configuration.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the AMT303-V's 96 PPR specification?

A: Yes. Both substitute parts feature programmable pulses per revolution, allowing configuration to 96 PPR operation to match the original AMT303-V specification.

Q: What is the primary difference between AMT313Q-V and AMT313S-V?

A: The termination style differs. AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface. All other electrical and mechanical parameters remain identical.

Q: Are the substitute parts compatible with existing AMT303-V mounting locations?

A: Yes. Both AMT313Q-V and AMT313S-V maintain identical mounting type (chassis mount, motors), orientation (right angle), and actuator specifications (2mm to 8mm open center), ensuring mechanical compatibility with existing installations.

Q: Do the substitute parts meet current compliance requirements?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The original AMT303-V is RoHS compliant but obsolete.

Q: Which substitute should be selected for direct replacement with minimal integration changes?

A: AMT313Q-V is recommended for direct replacement applications, as it maintains terminal pin termination identical to the AMT303-V, requiring no interface modifications.
