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 and 2-pole right-angle orientation. This encoder is designed for chassis mount and motor applications with a 5V supply voltage and open center actuator (2mm–8mm range).

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring this encoder's specific electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Incremental (required match)
• Voltage Supply: 5V (required match)
• Actuator Type: 2mm–8mm Open Center (required match)
• Mounting Type: Chassis Mount, Motors (required match)
• Orientation: Right Angle (required match)
• Termination Style: Terminal Pins or Connector (acceptable variations)
• Output Type: Commutation (required match)
• Pulses per Revolution: 800 fixed or Programmable (acceptable variation)

The substitute parts AMT313Q-V and AMT313S-V maintain all critical electrical and mechanical parameters. Both are active products from CUI Devices with identical supply voltage, actuator configuration, mounting type, and orientation. The key difference is that substitute parts feature programmable pulses per revolution, allowing configuration to 800 PPR to match the AMT303-V specification. Termination style varies between the substitutes: 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 status, providing supply chain continuity for applications currently using the obsolete AMT303-V.

AMT313Q-V is the preferred substitute when terminal pin termination is required. This part maintains identical termination style to the original AMT303-V, minimizing integration changes. The programmable pulses per revolution feature allows configuration to 800 PPR, matching the original specification exactly. ROHS3 compliance exceeds the original RoHS Compliant status.

AMT313S-V is suitable for applications where connector-based termination is acceptable or preferred. This part provides the same electrical and mechanical compatibility as AMT313Q-V but with connector termination instead of terminal pins. Selection of this substitute requires confirmation that the connector interface is compatible with the application's wiring and integration requirements.

Both substitutes are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Inventory availability is confirmed for both parts.

Frequently Asked Questions (FAQ)

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

A: Both parts are functionally equivalent in terms of electrical performance and mechanical mounting. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector. Selection depends on the application's wiring interface requirements.

Q: What is the significance of "Programmable" pulses per revolution in the substitute parts?

A: The substitute parts feature programmable PPR, allowing configuration to 800 PPR to match the AMT303-V specification. This flexibility provides additional functionality beyond the fixed 800 PPR of the original part.

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

A: The AMT303-V is RoHS Compliant, while both substitutes are ROHS3 Compliant. ROHS3 represents a more recent compliance standard. All three parts are REACH Unaffected and share identical moisture sensitivity levels (MSL 1 – Unlimited).

Q: Which substitute should be selected for new designs?

A: For new designs, either AMT313Q-V or AMT313S-V is appropriate based on termination requirements. AMT313Q-V is recommended if terminal pin integration is required; AMT313S-V is recommended if connector-based integration is preferred or required.

Q: Are the substitute parts currently in stock?

A: Yes. AMT313Q-V has 1349 pieces in stock, and AMT313S-V has 1045 pieces in stock, both listed as new original inventory.
