AS5311-ATST Rotary Encoder Magnetic PWM - Equivalent & Substitute Parts

Part Overview

The AS5311-ATST is an active magnetic rotary encoder manufactured by ams-OSRAM USA INC., designed for surface mount applications requiring PWM output signal generation. This component operates with external magnet actuation and is classified as an Active product status component. The encoder provides dual voltage supply compatibility (3.3V and 5V) and is suitable for applications requiring contactless rotational position sensing with magnetic field detection technology.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, ensuring functional interchangeability within the defined operating constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS5311-ATST is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Encoder Type: Magnetic
• Output Type: PWM
• Voltage Supply Range: 3.3V, 5V
• Actuator Type: External Magnet, Not Included
• Mounting Type: Surface Mount
• Termination Style: SMD (SMT) Tab
• Packaging Format: Tape & Reel (TR)
• RoHS Compliance: RoHS Compliant
• MSL Rating: 3 (168 Hours)

The AS5311-ATST-500 meets all mandatory parameter requirements and is classified as a direct substitute. Both components share the same base product number (AS5311), manufacturer (ams-OSRAM USA INC.), and functional specifications. Substitution is valid when these parameters remain constant across the application circuit design.

Parameter Comparison

Engineering Selection Recommendations

Both the AS5311-ATST and AS5311-ATST-500 are Active status components manufactured by ams-OSRAM USA INC. and carry identical compliance certifications (RoHS Compliant, REACH Unaffected, EAR99 classification). Selection between these parts is based on inventory availability and application lead time requirements rather than functional or electrical differences.

The AS5311-ATST maintains higher inventory levels (17,918 Pcs) compared to the AS5311-ATST-500 (5,628 Pcs), making it the primary selection for standard procurement. The AS5311-ATST-500 serves as an equivalent alternative when primary stock is unavailable or when specific supply chain requirements necessitate part number variation.

Both components are suitable for direct substitution in surface mount PCB assemblies requiring magnetic rotary encoding with PWM output at 3.3V or 5V supply voltages. No circuit redesign or validation testing is required when substituting between these parts, provided the external magnet actuator and mounting configuration remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can AS5311-ATST-500 be used as a direct replacement for AS5311-ATST in production?

A: Yes. Both parts share identical electrical specifications, output characteristics, supply voltage ranges, mounting type, and termination style. No circuit modifications are required for substitution.

Q: What is the difference between AS5311-ATST and AS5311-ATST-500?

A: The parts are functionally equivalent. The suffix designation (-500) indicates a specific manufacturing batch or inventory tracking variant. All electrical and mechanical parameters are identical.

Q: Are there any compatibility concerns with SMD (SMT) Tab termination when substituting between these parts?

A: No. Both components use identical SMD (SMT) Tab termination style and are packaged in Tape & Reel (TR) format. PCB footprints and reflow soldering profiles remain unchanged.

Q: Do both parts support the same voltage supply range?

A: Yes. Both AS5311-ATST and AS5311-ATST-500 operate at 3.3V and 5V supply voltages with identical electrical performance across the specified range.

Q: What is the Moisture Sensitivity Level (MSL) for these components?

A: Both parts carry MSL 3 rating with a 168-hour floor life. Standard moisture control procedures for MSL 3 components apply to both parts during storage and assembly.

Q: Are both parts RoHS compliant?

A: Yes. Both AS5311-ATST and AS5311-ATST-500 are RoHS Compliant and REACH Unaffected, meeting environmental regulatory requirements for EU and global markets.

Q: Can these encoders function without an external magnet?

A: No. Both components require an external magnet actuator for operation. The magnet is not included with the component and must be supplied separately as part of the mechanical assembly.
