AMT133S-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT133S-V is an incremental rotary encoder manufactured by CUI Devices, designed for chassis mount and motor applications with right-angle orientation. This encoder outputs programmable voltage signals and operates within a 4.5V to 5.5V supply range. The product is currently active and in stock with 1097 units available. Finding equivalent substitute parts may be necessary due to supply constraints, lead time requirements, or specific application needs while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

The AMT13A3S-V qualifies as a direct substitute for the AMT133S-V based on the following critical parameters that determine functional interchangeability:

• Encoder Type: Both are incremental encoders
• Output Type: Both provide voltage output
• Pulses per Revolution: Both are programmable
• Voltage Supply Range: Both operate at 4.5V ~ 5.5V
• Actuator Type: Both feature open center design
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both are right-angle configuration
• Termination Style: Both use connector termination
• Detent and Built-in Switch: Both lack these features
• Regulatory Compliance: Both are ROHS3 compliant and REACH unaffected

The primary difference lies in the series designation (AMT13 versus AMT13A) and moisture sensitivity level classification, which does not affect electrical or mechanical substitution capability.

Parameter Comparison

Engineering Selection Recommendations

Both the AMT133S-V and AMT13A3S-V are active products with full regulatory compliance under ROHS3 and REACH standards. Selection between these parts should be based on:

• Availability: The AMT13A3S-V currently has higher inventory (1249 units versus 1097 units)
• Supply chain requirements: Either part meets identical electrical and mechanical specifications
• Moisture sensitivity classification: The AMT13A3S-V carries MSL 1 (Unlimited) versus Not Applicable for the AMT133S-V, which may be relevant for storage and handling in high-humidity environments

Both encoders are suitable for direct substitution in applications requiring incremental voltage output with programmable pulse resolution and right-angle chassis mount configuration.

Frequently Asked Questions (FAQ)

Q: Can the AMT13A3S-V replace the AMT133S-V in existing designs?

A: Yes. Both encoders share identical electrical specifications (4.5V ~ 5.5V supply, programmable voltage output, incremental encoding) and mechanical characteristics (right-angle orientation, open center actuator, connector termination, chassis mount compatibility). No circuit or mechanical modifications are required.

Q: What is the difference between the AMT13 and AMT13A series?

A: The series designation reflects internal product line organization within CUI Devices. From a functional standpoint, the AMT133S-V and AMT13A3S-V are electrically and mechanically equivalent for substitution purposes.

Q: Does moisture sensitivity level affect substitution suitability?

A: Moisture sensitivity level (MSL) classification impacts storage, handling, and shelf-life management but does not affect electrical or mechanical performance. The AMT13A3S-V carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. This may provide advantages in environments with extended storage or high-humidity conditions.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the AMT133S-V and AMT13A3S-V are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What packaging is provided with these encoders?

A: Both parts are supplied in box packaging as complete kits, including all necessary components for installation.
