AS5147-HTST Rotary Encoder Magnetic Programmable - Equivalent & Substitute Parts

Part Overview

The AS5147-HTST is a surface-mount rotary encoder with magnetic sensing technology, manufactured by ams-OSRAM USA INC. This component provides programmable commutation, PWM, SPI, and quadrature output with index functionality for incremental position detection. The part operates across dual voltage ranges (3V–3.6V and 4.5–5.5V) and is qualified to AEC-Q100 automotive standards. As an active product with 7,607 units in stock, the AS5147-HTST serves applications requiring reliable rotational feedback in automotive and industrial environments. Substitute parts are identified based on identical electrical specifications, mechanical compatibility, and compliance certifications.

Substitute Part Grouping Explanation

Substitute parts for the AS5147-HTST are identified based on strict parameter equivalence within the AS5147 base product family. The substitution logic is determined by the following critical parameters:

Substitution Criteria:

• Identical encoder type (Magnetic)
• Identical output type (Commutation, PWM, SPI, Quadrature with index)
• Identical voltage supply ranges (3V–3.6V, 4.5–5.5V)
• Identical mounting type (Surface Mount)
• Identical termination style (SMD Tab)
• Identical automotive grade and AEC-Q100 qualification
• Identical RoHS compliance and MSL rating
• Same base product number (AS5147)

The AS5147-HTST differs from substitute parts only in packaging designation suffix (HTST vs. HTSM). Both packaging variants maintain identical electrical and mechanical specifications, allowing direct substitution in applications where tape and reel packaging is acceptable.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AS5147-HTST, AS5147-HTSM, and AS5147P-HTSM—are functionally equivalent for applications requiring magnetic rotary encoding with programmable output modes. Selection among these parts should be based on the following factors:

Product Status & Availability: All three parts maintain active product status with full AEC-Q100 automotive qualification and RoHS compliance. AS5147P-HTSM offers the highest inventory availability (8,430 units), followed by AS5147-HTST (7,607 units) and AS5147-HTSM (1,772 units).

Compliance & Certification: All parts satisfy identical automotive-grade requirements, moisture sensitivity specifications (MSL 3), and regulatory compliance (RoHS, REACH Unaffected, EAR99 ECCN classification).

Packaging Considerations: All parts are supplied in tape and reel packaging suitable for automated assembly processes. The suffix designation (HTST vs. HTSM) reflects packaging variant differences that do not affect electrical or mechanical performance.

Supply Chain Continuity: When primary part availability is constrained, any of the three substitutes provides equivalent functionality without design modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can AS5147-HTSM or AS5147P-HTSM be used as direct replacements for AS5147-HTST?

A: Yes. All three parts share identical electrical specifications, output configurations, voltage ranges, and automotive qualifications. They are mechanically and functionally interchangeable in surface-mount applications.

Q: What is the difference between the HTST and HTSM packaging designations?

A: The suffix designations indicate packaging variant classifications within the tape and reel format. Both variants maintain identical component specifications and are suitable for automated pick-and-place assembly.

Q: Are there any voltage or output mode differences between these parts?

A: No. All three parts operate across the same dual voltage ranges (3V–3.6V and 4.5–5.5V) and provide identical output modes: commutation, PWM, SPI, and quadrature with index.

Q: Do all parts require the same external magnet configuration?

A: Yes. All three parts use external magnet actuation (not included) and require identical magnet positioning and specifications for proper operation.

Q: Which part should be selected for new designs?

A: Selection should prioritize inventory availability and supply chain reliability. AS5147P-HTSM offers the highest stock level (8,430 units), making it suitable for high-volume production. AS5147-HTST and AS5147-HTSM are equivalent alternatives when primary selection is unavailable.

Q: Are all parts AEC-Q100 qualified?

A: Yes. All three parts carry full AEC-Q100 automotive qualification and are suitable for automotive-grade applications requiring rotational feedback sensing.

Q: What is the moisture sensitivity level for these parts?

A: All parts are rated MSL 3 with a 168-hour floor life. Standard moisture control procedures during storage and assembly are required.
