AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 1000 pulses per revolution with commutation output in counter-clockwise (CCW) orientation. This encoder features a right-angle mounting configuration with a 2mm to 8mm open center actuator and operates at 5V supply voltage. The product 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 that must align across candidate parts:

• Encoder Type: Incremental operation required
• Voltage Supply: 5V operation mandatory
• Actuator Type: 2mm to 8mm open center configuration
• Mounting Type: Chassis mount and motor mounting compatibility
• Orientation: Right angle configuration
• Output Compatibility: Commutation output with matching electrical characteristics

The substitute parts AMT313Q-V and AMT313S-V are qualified alternatives because they maintain identical specifications for encoder type, supply voltage, actuator dimensions, mounting type, and orientation. Both substitutes feature programmable pulses per revolution, which encompasses the fixed 1000 PPR specification of the AMT303-V. The primary 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 replacement for AMT303-V in applications requiring terminal pin termination. Both parts share identical termination methodology, enabling direct integration into existing PCB layouts and connector assemblies without modification. The AMT313Q-V maintains active product status with ROHS3 compliance, providing long-term supply chain stability and regulatory alignment superior to the obsolete AMT303-V.

AMT313S-V provides equivalent electrical and mechanical functionality with connector-based termination. Selection of this variant is appropriate for applications where connector interfaces are preferred or where system architecture supports modular connector-based encoder integration. The connector termination style requires interface compatibility verification with the receiving system.

Both substitutes support programmable pulses per revolution configuration, allowing the 1000 PPR specification of the AMT303-V to be established through programming rather than hardware selection. This feature provides additional flexibility for applications requiring future PPR adjustments without component replacement.

Frequently Asked Questions (FAQ)

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

A: Both are functionally equivalent substitutes for the AMT303-V. Selection between them depends on termination requirements: AMT313Q-V for terminal pin applications, AMT313S-V for connector-based systems.

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

A: The termination style differs. AMT313Q-V uses terminal pins identical to AMT303-V, while AMT313S-V uses a connector interface. All other electrical and mechanical specifications are equivalent.

Q: Does the programmable PPR feature of the substitutes affect compatibility?

A: No. The programmable PPR capability of AMT313Q-V and AMT313S-V encompasses the fixed 1000 PPR specification of AMT303-V. The substitutes can be configured to operate at 1000 PPR, maintaining functional equivalence.

Q: Are there compliance differences between the main part and substitutes?

A: The substitutes feature ROHS3 compliance compared to the RoHS compliance of the obsolete AMT303-V. Both maintain REACH Unaffected status and MSL 1 (Unlimited) ratings. The enhanced compliance of active substitutes supports current regulatory requirements.

Q: What inventory status should influence part selection?

A: AMT313Q-V and AMT313S-V are both active products with substantial inventory availability (1349 and 1045 units respectively), compared to the obsolete AMT303-V. Active status ensures continued supply chain access and technical support.
