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

Part Overview

The AS5045B-ASST 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 across dual voltage supply ranges (3V ~ 3.6V and 4.5V ~ 5.5V) and utilizes an external magnet actuator configuration without integrated detent or switch functionality.

The AS5045B-ASST maintains Active product status with full RoHS compliance and REACH unaffected classification. Identifying equivalent substitute parts becomes necessary when addressing supply chain constraints, packaging format requirements, or inventory optimization while maintaining identical electrical and mechanical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence Criteria:

• Encoder type classification (Magnetic)
• Output signal format (PWM)
• Dual voltage supply compatibility (3V ~ 3.6V and 4.5V ~ 5.5V)
• Actuator configuration (External Magnet, Not Included)

Mechanical Equivalence Criteria:

• Surface mount mounting type
• SMD (SMT) Tab termination style
• Absence of detent and built-in switch functions
• Base product number (AS5045 family)

Compliance Equivalence Criteria:

• RoHS Compliant status
• REACH Unaffected classification
• Moisture Sensitivity Level 3 (168 Hours)

The AS5045-ASST qualifies as a direct substitute based on identical electrical specifications, mechanical configuration, and regulatory compliance. The primary distinction between these parts exists in packaging format only.

Parameter Comparison

Engineering Selection Recommendations

Both AS5045B-ASST and AS5045-ASST maintain Active product status with confirmed RoHS compliance and REACH unaffected classification. Selection between these parts is determined exclusively by packaging and supply chain requirements rather than functional performance.

AS5045B-ASST Selection Criteria:

• Tape & Reel (TR) packaging format required for automated assembly processes
• High-volume production runs with continuous feed requirements
• Current inventory: 18,313 pieces

AS5045-ASST Selection Criteria:

• Cut Tape (CT) and Digi-Reel® packaging format compatibility with existing procurement workflows
• Flexibility in order quantities and staging requirements
• Current inventory: 20,143 pieces

Both parts deliver identical electrical performance, mechanical integration, and regulatory compliance across all specified parameters. Substitution between these parts introduces no functional risk or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can AS5045-ASST replace AS5045B-ASST in production designs?

A: Yes. Both parts are electrically and mechanically equivalent across all functional parameters. The AS5045-ASST operates identically in circuit applications designed for the AS5045B-ASST. Substitution introduces no performance or compatibility issues.

Q: What is the primary difference between these two part numbers?

A: The packaging format differs. AS5045B-ASST ships in Tape & Reel (TR) format, while AS5045-ASST ships in Cut Tape (CT) and Digi-Reel® format. Electrical specifications, mechanical configuration, and compliance certifications remain identical.

Q: Are voltage supply ranges identical between both parts?

A: Yes. Both AS5045B-ASST and AS5045-ASST operate across the same dual voltage supply ranges: 3V ~ 3.6V and 4.5V ~ 5.5V. Circuit designs require no modification when substituting between these parts.

Q: Do both parts require external magnet actuators?

A: Yes. Both AS5045B-ASST and AS5045-ASST utilize external magnet actuator configuration with magnets not included in the package. Identical external magnet specifications apply to both parts.

Q: What is the Moisture Sensitivity Level for both parts?

A: Both parts carry Moisture Sensitivity Level 3 (168 Hours). Identical moisture handling and storage protocols apply to AS5045B-ASST and AS5045-ASST.

Q: Are both parts RoHS compliant?

A: Yes. Both AS5045B-ASST and AS5045-ASST maintain full RoHS compliance and REACH unaffected status. No regulatory differences exist between these parts.

Q: Which part should I select for automated assembly?

A: AS5045B-ASST in Tape & Reel (TR) format is optimized for continuous automated pick-and-place assembly processes. AS5045-ASST in Cut Tape (CT) format accommodates manual or semi-automated handling workflows.
