AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 800 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 alternative models that maintain functional and mechanical compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303-V is determined by the following critical parameters:

• Encoder Type: Must be Incremental
• Voltage Supply: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Manufacturer: CUI Devices (same manufacturer ecosystem)

The substitute parts AMT313Q-V and AMT313S-V satisfy these core mechanical and electrical compatibility requirements. Both are active products with programmable pulses per revolution capability, providing functional flexibility beyond the fixed 800 PPR specification of the obsolete AMT303-V. The key distinction between substitutes lies in termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the direct functional substitute for AMT303-V when terminal pin termination is required. Both parts share identical termination style, maintaining compatibility with existing PCB layouts and connector designs. AMT313Q-V holds active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The programmable pulses per revolution feature provides design flexibility for applications requiring resolution adjustment without component replacement.

AMT313S-V serves as an alternative when connector-based termination is acceptable or preferred. This configuration offers the same electrical and mechanical compatibility as AMT313Q-V but with a connector interface instead of terminal pins. Selection of AMT313S-V requires PCB or assembly redesign to accommodate the connector termination style.

Both substitutes maintain compliance with REACH and RoHS regulations, with moisture sensitivity level unchanged from the original part.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V directly replace AMT303-V without PCB modification?

A: Yes. AMT313Q-V maintains identical termination style (terminal pins), mounting type (chassis mount), orientation (right angle), and electrical specifications (5V supply). No PCB layout changes are required for direct substitution.

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

A: The AMT313Q-V and AMT313S-V offer programmable PPR capability, allowing configuration to 800 PPR or other resolutions as needed. This eliminates the need for multiple part numbers in inventory and provides design flexibility for applications with varying resolution requirements.

Q: Is AMT313S-V compatible with existing AMT303-V installations?

A: AMT313S-V is electrically and mechanically compatible but requires assembly redesign due to connector termination instead of terminal pins. This substitution is suitable for new designs or retrofit applications where connector integration is feasible.

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

A: The substitute parts (AMT313Q-V and AMT313S-V) carry ROHS3 compliance, representing an updated regulatory standard compared to the RoHS Compliant designation of AMT303-V. Both maintain REACH Unaffected status. This upgrade ensures compliance with current environmental regulations.

Q: What is the inventory status of substitute parts?

A: AMT313Q-V has 1349 units in stock, and AMT313S-V has 1045 units in stock, both classified as new original inventory. The obsolete AMT303-V has 704 units remaining in stock.
