AS5247-HMFT Rotary Encoder Magnetic Programmable PWM: Equivalent & Substitute Parts

Part Overview

The AS5247-HMFT is an active, automotive-grade rotary encoder manufactured by ams-OSRAM USA INC. This magnetic programmable encoder outputs PWM signals and operates across dual voltage supply ranges (3V–3.6V and 4.5V–5.5V). The device uses an external magnet actuator and surface mount termination, making it suitable for embedded motion control and position sensing applications requiring programmable pulse resolution. Substitute parts are identified based on matching electrical specifications, mechanical compatibility, and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS5247-HMFT is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Encoder Type: Magnetic
• Output Type: PWM
• Pulses per Revolution: Programmable
• 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
• RoHS Compliance: Yes
• MSL Rating: 3 (168 Hours)
• REACH Status: REACH Unaffected

All identified substitute parts (AS5047D-ATSM, AS5047D-ATST, AS5047P-ATSM, AS5247-HMFM) match these parameters exactly. Differences in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and inventory availability do not affect functional or electrical compatibility. The AS5247-HMFM variant maintains automotive-grade qualification and AEC-Q100 certification identical to the main part.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (AS5247-HMFM): The AS5247-HMFM is the preferred substitute when automotive-grade qualification and AEC-Q100 certification are required. This part maintains identical electrical specifications, compliance status, and automotive qualification as the AS5247-HMFT. The only difference is packaging format (Tape & Reel). Current inventory is 3,816 units.

Secondary Selection (AS5047D-ATST): The AS5047D-ATST provides full electrical and mechanical compatibility with Tape & Reel packaging. This part is based on the AS5047 platform and does not carry explicit automotive-grade designation or AEC-Q100 certification in the provided specifications. Current inventory is 21,974 units.

Tertiary Selection (AS5047D-ATSM or AS5047P-ATSM): Both AS5047D-ATSM and AS5047P-ATSM offer electrical compatibility with Cut Tape & Digi-Reel packaging. These options provide the highest inventory availability (22,274 and 34,466 units respectively) but do not carry automotive-grade or AEC-Q100 certification. Selection should be based on packaging requirements and supply chain constraints.

Compliance Consideration: Applications requiring automotive-grade components and AEC-Q100 qualification must use either AS5247-HMFT or AS5247-HMFM. The AS5047 series variants do not carry these certifications in the provided data.

Frequently Asked Questions (FAQ)

Q: Can AS5047D-ATSM replace AS5247-HMFT in automotive applications?

A: Electrical and mechanical compatibility is confirmed. However, the AS5047D-ATSM does not carry automotive-grade designation or AEC-Q100 certification in the provided specifications. For applications requiring automotive qualification, use AS5247-HMFM instead.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Packaging format affects supply chain handling and assembly line integration. Tape & Reel (TR) is continuous reel format. Cut Tape (CT) & Digi-Reel® is pre-cut tape with reel option. Electrical and functional performance are identical. Selection depends on manufacturing equipment compatibility and order quantity requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts (AS5047D-ATSM, AS5047D-ATST, AS5047P-ATSM, AS5247-HMFM) are RoHS Compliant with REACH Unaffected status, matching the AS5247-HMFT.

Q: Do substitute parts support the same voltage supply ranges?

A: Yes. All substitute parts operate across identical voltage supply ranges: 3V–3.6V and 4.5V–5.5V. No circuit redesign is required for voltage compatibility.

Q: What is the MSL rating and why does it matter?

A: All parts carry MSL 3 (168 Hours), indicating moisture sensitivity level 3 with a floor life of 168 hours after moisture exposure. Storage and handling procedures must comply with this rating to prevent solder joint degradation during assembly.

Q: Can I use AS5047P-ATSM if I need high inventory availability?

A: Yes. The AS5047P-ATSM provides the highest inventory (34,466 units) with full electrical and mechanical compatibility. Confirm that automotive-grade qualification is not a requirement for your application before selection.

Q: Are the programmable pulse resolution settings identical across all substitute parts?

A: Yes. All parts support programmable pulses per revolution. Configuration and programming procedures are equivalent across the AS5247 and AS5047 series variants listed.
