AS5045B-ASSM Rotary Encoder Magnetic PWM - Equivalent & Substitute Parts

Part Overview

The AS5045B-ASSM is an active magnetic rotary encoder manufactured by ams-OSRAM USA INC. that generates PWM output signals for rotational position detection. This Surface Mount Device (SMD) component operates across dual voltage ranges (3V ~ 3.6V and 4.5V ~ 5.5V) and utilizes an external magnet actuator mechanism. The device is supplied in Tape & Reel (TR) packaging with 2200 units currently in stock inventory.

The AS5045B-ASSM maintains Active product status and holds RoHS Compliant certification with REACH Unaffected designation. Substitute part identification becomes necessary when Tape & Reel packaging is unavailable or when alternative packaging formats better suit production requirements, while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS5045B-ASSM is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Encoder Type: Magnetic
• Output Type: PWM
• Voltage Supply Range: 3V ~ 3.6V and 4.5V ~ 5.5V
• Actuator Type: External Magnet, Not Included
• Mounting Type: Surface Mount
• Termination Style: SMD (SMT) Tab
• Base Product Number: AS5045
• RoHS Compliance: RoHS Compliant
• REACH Status: REACH Unaffected

Variable Parameter (Non-Critical for Substitution):

• Packaging Format: Tape & Reel (TR) vs. Cut Tape (CT) & Digi-Reel®

The AS5045-ASST qualifies as a direct substitute because it maintains identical electrical specifications, mechanical configuration, and regulatory compliance while differing only in packaging delivery method. Both components share the same base product number (AS5045) and are manufactured by the same supplier (ams-OSRAM USA INC.).

Parameter Comparison

Engineering Selection Recommendations

AS5045B-ASSM Selection Criteria:

• Preferred when Tape & Reel (TR) packaging is required for automated assembly processes
• Current inventory: 2200 units
• Maintains Active product status with full RoHS Compliance and REACH Unaffected designation

AS5045-ASST Selection Criteria:

• Suitable when Cut Tape (CT) or Digi-Reel® packaging formats align with procurement and assembly workflows
• Higher inventory availability: 20143 units
• Identical electrical performance and regulatory compliance to AS5045B-ASSM
• Maintains Active product status with full RoHS Compliance and REACH Unaffected designation

Both components are manufactured by ams-OSRAM USA INC. and share identical core specifications. Selection between these parts should be based solely on packaging format requirements and inventory availability. No functional or compliance differences exist between the two part numbers.

Frequently Asked Questions (FAQ)

Q: Can AS5045-ASST be used as a direct replacement for AS5045B-ASSM in circuit design?

A: Yes. Both components share identical electrical specifications, voltage supply ranges (3V ~ 3.6V and 4.5V ~ 5.5V), PWM output type, and magnetic encoder functionality. The only difference is packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®), which does not affect circuit performance or pin configuration.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for high-volume automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging provides components in smaller quantities on cut tape segments or alternative reel formats, suitable for lower-volume production or manual assembly workflows. Both packaging formats contain identical components with identical specifications.

Q: Are there any compliance or certification differences between AS5045B-ASSM and AS5045-ASST?

A: No. Both components maintain identical RoHS Compliant status, REACH Unaffected designation, Moisture Sensitivity Level (MSL) 3 rating, and Active product status. No compliance or certification differences exist.

Q: What is the Moisture Sensitivity Level (MSL) 3 specification?

A: MSL 3 indicates the component can be exposed to moisture for a maximum of 168 hours before soldering. This specification applies equally to both AS5045B-ASSM and AS5045-ASST and must be observed during storage and handling prior to assembly.

Q: Can I mix AS5045B-ASSM and AS5045-ASST components in the same production batch?

A: Yes. Both components are electrically and mechanically identical. Mixing packaging formats in a single production batch is permissible from a functional and compliance perspective, though assembly process workflows may require separate handling procedures based on packaging format.

Q: What external magnet specifications are required for operation?

A: The AS5045B-ASSM and AS5045-ASST both utilize external magnet actuators that are not included with the component. Specific magnet specifications are not provided in the component documentation. Consult the detailed product datasheet for magnet type, strength, and positioning requirements.
