Substitute Part Grouping Explanation

Substitute parts for the AS5147P-HTST are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Compatibility:

• Identical encoder type (Magnetic)
• Identical output types (Commutation, PWM, SPI, Quadrature with index)
• Identical programmable pulses per revolution capability
• Identical dual voltage supply ranges (3V–3.6V and 4.5V–5.5V)

Mechanical & Package Compatibility:

• Identical actuator type (External Magnet, Not Included)
• Identical mounting type (Surface Mount)
• Identical termination style (SMD/SMT Tab)
• Identical packaging format (Tape & Reel)

Compliance & Qualification:

• Identical automotive grade classification
• Identical AEC-Q100 qualification
• Identical RoHS compliance status
• Identical Moisture Sensitivity Level (MSL 3)

The identified substitutes differ only in part number designation and inventory availability, with no variation in functional or physical specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AS5147P-HTST, AS5147P-HTSM, and AS5147-HTSM—are functionally equivalent and directly interchangeable from an electrical and mechanical standpoint. Selection between these parts should be based on the following factors:

Inventory Availability: AS5147P-HTSM offers the highest stock level at 8430 units, followed by AS5147-HTSM at 1772 units, and AS5147P-HTST at 1573 units. For high-volume production or extended lead-time mitigation, AS5147P-HTSM is the preferred choice.

Compliance & Certification: All three parts carry identical automotive-grade classification and AEC-Q100 qualification, making them suitable for automotive applications without additional qualification testing.

RoHS & Environmental Compliance: All parts are RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Moisture Sensitivity: All parts share MSL 3 (168 Hours) rating, requiring identical handling and storage protocols during manufacturing and assembly.

Frequently Asked Questions (FAQ)

Q: Can AS5147P-HTSM be used as a direct replacement for AS5147P-HTST?

A: Yes. Both parts are electrically and mechanically identical. They share the same encoder type, output formats, voltage ranges, mounting specifications, and automotive qualifications. The part numbers differ only in internal designation; no design changes or compatibility issues exist.

Q: What is the difference between AS5147P-HTSM and AS5147-HTSM?

A: Both parts are functionally equivalent with identical electrical specifications, output types, voltage ranges, and automotive qualifications. The difference lies in part number designation only. Both are suitable for direct substitution in applications requiring the AS5147P-HTST.

Q: Are these parts suitable for automotive applications?

A: Yes. All three parts carry Automotive grade classification and AEC-Q100 qualification, confirming suitability for automotive-grade applications.

Q: Do these parts require external components for operation?

A: The actuator type is External Magnet, Not Included. An external magnet must be provided separately for rotational sensing. The encoder itself requires no additional external components for basic operation.

Q: What voltage ranges are supported?

A: All three parts support dual voltage ranges: 3V–3.6V and 4.5V–5.5V. System design must specify which range applies to the application.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are RoHS Compliant and REACH Unaffected, meeting current environmental regulations.

Q: What is the Moisture Sensitivity Level, and what does it mean?

A: All parts have MSL 3 (168 Hours). This indicates the maximum time the component can be exposed to ambient conditions (typically 30°C/85% RH) before soldering. Components must be stored in dry conditions and baked before assembly if exposure time is exceeded.

Q: Can I mix these part numbers in the same production batch?

A: Yes. Since all three parts are electrically and mechanically identical, they can be used interchangeably within the same assembly without design or functional impact.
