SFH 4717S Infrared Emitter - Equivalent & Substitute Parts

Part Overview

The SFH 4717S is an infrared (IR) emitter manufactured by ams-OSRAM USA INC., part of the OSLON® Black series. This component is a surface-mount infrared emitter operating at 860nm wavelength with a maximum forward current of 1A and typical forward voltage of 2.95V. The device features a 50° viewing angle and is housed in a 1515 (3838 Metric) package.

The SFH 4717S has reached obsolete product status. Locating equivalent or substitute components is necessary to support ongoing system maintenance, repair, and redesign efforts where this emitter is specified in existing designs or inventory management requires active alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SFH 4717S is determined by the following critical parameters:

Mandatory Matching Parameters:

• Wavelength: 860nm (infrared spectrum compatibility)
• Package / Case: 1515 (3838 Metric) (mechanical fit and PCB footprint)
• Mounting Type: Surface Mount (assembly process compatibility)
• Viewing Angle: 50° (optical field-of-view requirement)
• Operating Temperature Range: -40°C to 125°C (thermal envelope)

Allowable Parameter Variations:

• Current - DC Forward (If) Max: Substitute may exceed the original specification (1A) provided the circuit design accommodates higher current capability
• Voltage - Forward (Vf) Typical: Substitute may differ within the operating range of the driver circuit
• Radiant Intensity (Ie): Enhanced optical output is permissible if the application does not require exact intensity matching

The SFH 4717AS qualifies as a manufacturer-recommended substitute based on these criteria. All mandatory parameters align with the SFH 4717S, while allowable variations in current, voltage, and radiant intensity provide enhanced performance characteristics.

Engineering Selection Recommendations

Primary Substitute: SFH 4717AS

The SFH 4717AS is the manufacturer-recommended substitute for the obsolete SFH 4717S. Selection of this component is based on the following engineering factors:

Compliance & Regulatory:

• Both components maintain ROHS3 compliance and REACH unaffected status
• Identical moisture sensitivity level (MSL 2, 1 Year) ensures equivalent handling and storage requirements
• Both components carry the same ECCN (EAR99) and HTSUS (8541.41.0000) classifications

Product Lifecycle:

• The SFH 4717AS holds active product status, ensuring long-term availability and supply chain continuity
• The SFH 4717S is obsolete, making the SFH 4717AS the appropriate forward-looking component selection

Electrical & Optical Compatibility:

• Identical wavelength (860nm), viewing angle (50°), and operating temperature range (-40°C to 125°C) ensure functional equivalence in infrared applications
• The SFH 4717AS operates within the same package footprint (1515 / 3838 Metric), permitting direct PCB substitution without layout modification
• Higher maximum forward current (1.5A vs. 1A) and typical forward voltage (3.15V vs. 2.95V) require verification that the driver circuit can accommodate these parameters; however, these represent performance enhancements rather than incompatibilities

Inventory & Availability:

• The SFH 4717AS is currently in stock (828 Pcs), supporting immediate procurement for new designs and replacement applications

Frequently Asked Questions (FAQ)

Q: Can the SFH 4717AS be used as a direct replacement for the SFH 4717S on existing PCBs?

A: Yes. Both components share identical package dimensions (1515 / 3838 Metric), mounting type (surface mount), and PCB footprint. No layout modifications are required. However, the driver circuit must be verified to operate with the SFH 4717AS electrical parameters (1.5A maximum current, 3.15V typical forward voltage).

Q: What is the difference in forward voltage between these two parts?

A: The SFH 4717S has a typical forward voltage of 2.95V, while the SFH 4717AS is rated at 3.15V. This 0.2V difference must be accommodated by the driver circuit. If the original design operates at the voltage limit, the substitute may require driver adjustment or verification.

Q: Why does the SFH 4717AS have a higher maximum forward current rating?

A: The SFH 4717AS is rated for 1.5A maximum forward current compared to 1A for the SFH 4717S. This represents an enhanced specification within the same package. The circuit design determines the actual operating current; the higher rating provides additional operational margin and does not require the circuit to draw more current than originally designed.

Q: Are the optical characteristics identical between these parts?

A: Both components operate at 860nm wavelength with a 50° viewing angle. The SFH 4717AS specifies a radiant intensity of 900mW/sr @ 1A, while the SFH 4717S does not provide this specification. The identical wavelength and viewing angle ensure optical compatibility in infrared applications.

Q: What is the significance of the SFH 4717S being obsolete?

A: Obsolete status indicates that the SFH 4717S is no longer manufactured by ams-OSRAM USA INC. The SFH 4717AS, with active product status, is the recommended path forward for new designs and ongoing production. Existing inventory of the SFH 4717S should be managed accordingly, with transition planning to the SFH 4717AS.

Q: Are there any differences in handling or storage requirements?

A: No. Both components carry identical moisture sensitivity level (MSL 2, 1 Year) ratings, requiring the same handling, storage, and reflow procedures. No changes to manufacturing processes are necessary when transitioning from SFH 4717S to SFH 4717AS.

Q: What compliance certifications apply to the SFH 4717AS?

A: The SFH 4717AS is ROHS3 compliant, REACH unaffected, and carries ECCN EAR99 and HTSUS 8541.41.0000 classifications. These certifications are identical to the SFH 4717S, ensuring regulatory equivalence.
