AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 200 pulses per revolution with commutation output in a right-angle chassis mount configuration. This encoder is classified as obsolete, making identification of functionally equivalent alternatives 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 equivalence:

Core Compatibility Parameters:

• Encoder Type: Incremental
• 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)
• REACH Status: REACH Unaffected

Substitution Allowance:

• Output Type: Commutation (fixed requirement)
• Pulses per Revolution: Fixed at 200 for AMT303-V; substitutes feature programmable PPR capability
• Termination Style: Terminal Pins (primary) or Connector (alternative)
• RoHS Status: RoHS Compliant or ROHS3 Compliant (both acceptable)

The substitute parts AMT313Q-V and AMT313S-V maintain all critical electrical and mechanical parameters. The primary distinction is programmable pulses per revolution capability in substitutes versus fixed 200 PPR in the original part. Both substitutes are active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V Selection Criteria: The AMT313Q-V maintains terminal pin termination identical to the AMT303-V, providing direct mechanical and electrical interface compatibility. This part is currently active in production with ROHS3 compliance certification. The programmable pulses per revolution feature allows configuration to 200 PPR to match the original specification, or alternative values as application requirements permit.

AMT313S-V Selection Criteria: The AMT313S-V offers connector-based termination as an alternative to terminal pins. This part is active in production with ROHS3 compliance. The connector interface may require harness or adapter modification depending on existing system integration. Programmable PPR capability provides the same flexibility as AMT313Q-V.

Compliance Status: Both substitute parts exceed the RoHS compliance level of the original part (ROHS3 vs. RoHS Compliant) and maintain REACH Unaffected status. Both are manufactured by the same supplier (CUI Devices), ensuring design continuity and technical support consistency.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V or AMT313S-V be directly substituted for AMT303-V without modification?

A: AMT313Q-V provides direct substitution with identical terminal pin termination. AMT313S-V requires connector interface adaptation. Both maintain all critical electrical parameters (5V supply, incremental encoding, commutation output, open center actuator, right-angle orientation, chassis mount configuration).

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

A: The primary difference is termination style. AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface. Both feature programmable pulses per revolution and identical electrical specifications.

Q: How does the programmable PPR feature affect substitution?

A: The AMT303-V operates at fixed 200 PPR. Substitute parts AMT313Q-V and AMT313S-V feature programmable PPR, allowing configuration to 200 PPR or alternative values. For direct functional replacement, configure substitutes to 200 PPR.

Q: Are there packaging differences between these parts?

A: AMT303-V packaging is listed as standard. AMT313Q-V and AMT313S-V are supplied in box packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the inventory status of these parts?

A: AMT303-V (obsolete): 670 pieces in stock. AMT313Q-V (active): 1349 pieces in stock. AMT313S-V (active): 1045 pieces in stock.

Q: Do the substitute parts maintain the same RoHS and REACH compliance?

A: Yes. Substitute parts meet or exceed the original compliance level. AMT303-V is RoHS Compliant; substitutes are ROHS3 Compliant. All three parts maintain REACH Unaffected status.
