AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 250 pulses per revolution (PPR) output. This encoder features a right-angle orientation, chassis mount configuration, and terminal pin termination, operating at 5V supply voltage. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations where 250 PPR incremental encoding functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303-V is determined by the following critical parameters that must align across parts:

• Encoder Type: Incremental (required match)
• Voltage Supply: 5V (required match)
• Mounting Type: Chassis Mount, Motors (required match)
• Orientation: Right Angle (required match)
• Actuator Type: 2mm ~ 8mm Open Center (required match)
• Detent: No (required match)
• Built in Switch: No (required match)

The substitute parts AMT313Q-V and AMT313S-V satisfy all mandatory mechanical and electrical compatibility criteria. Both are active CUI Devices products within the AMT31 series. The primary distinction between substitutes is the termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

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

AMT313Q-V maintains terminal pin termination identical to the original AMT303-V, enabling direct mechanical and electrical integration into existing designs with minimal modification. This part is suitable for applications requiring pin-compatible replacement.

AMT313S-V provides connector-based termination, requiring interface adaptation but offering standardized connector integration benefits for new system designs or retrofit applications where connector interfaces are preferred.

Both substitutes feature programmable pulses per revolution capability, allowing configuration to 250 PPR or alternative resolution settings as required by system specifications.

Frequently Asked Questions (FAQ)

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

A: Both parts satisfy the core electrical and mechanical compatibility requirements. Selection depends on termination interface requirements. AMT313Q-V matches the terminal pin interface of the original; AMT313S-V requires connector interface adaptation.

Q: What is the significance of programmable PPR in the substitute parts?

A: The AMT313Q-V and AMT313S-V feature programmable pulses per revolution, allowing configuration to 250 PPR to match the fixed 250 PPR specification of the AMT303-V, or alternative resolutions as needed.

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

A: The AMT303-V carries RoHS Compliant certification. Both substitutes carry ROHS3 Compliant certification, representing current regulatory compliance standards.

Q: What packaging is provided with substitute parts?

A: AMT313Q-V and AMT313S-V are supplied in box packaging.

Q: Does product status affect substitution suitability?

A: The AMT303-V is obsolete, while both substitutes are active products with current manufacturing support. Active status ensures ongoing availability and supply chain reliability for future procurement.
