SFH 4716S Infrared Emitter Equivalent & Substitute Parts

Part Overview

The SFH 4716S is an infrared (IR) emitter operating at 860nm wavelength, designed for surface mount applications in the OSLON® Black series. This component is rated for 1A maximum DC forward current with a typical forward voltage of 2.9V and radiant intensity of 225mW/sr at 1A. The device features a 150° viewing angle and operates across the temperature range of -40°C to 125°C.

The SFH 4716S has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this infrared emitter.

Substitute Part Grouping Explanation

Substitute parts for the SFH 4716S are identified based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• Wavelength: 860nm (identical across all variants)
• Mounting Type: Surface Mount (consistent across all variants)
• Package / Case: 3-SMD, No Lead (consistent across all variants)
• Viewing Angle: 150° (consistent across all variants)
• Operating Temperature Range: -40°C to 125°C (consistent across all variants)
• Series: OSLON® Black (consistent across all variants)
• RoHS Status: ROHS3 Compliant (consistent across all variants)

Parameters Allowing Substitution: The SFH 4716AS is classified as a substitute part because it maintains identical wavelength, package configuration, mounting type, and environmental specifications. The substitute part operates within the same temperature range and maintains the same viewing angle and series designation. Both components share the same base product number (SFH4716) and comply with identical regulatory standards.

Parameter Comparison

Engineering Selection Recommendations

SFH 4716AS as Primary Substitute:

The SFH 4716AS is the designated substitute for the obsolete SFH 4716S. Both components share identical wavelength (860nm), package configuration (3-SMD, No Lead), mounting type (Surface Mount), viewing angle (150°), and operating temperature range (-40°C to 125°C). Both maintain ROHS3 compliance and REACH unaffected status.

The SFH 4716AS carries active product status, ensuring ongoing availability and supply chain support. The substitute part exhibits higher maximum forward current (1.5A versus 1A) and increased radiant intensity (300mW/sr @ 1A versus 225mW/sr @ 1A), with a slightly elevated typical forward voltage (3.2V versus 2.9V).

Circuit designs operating the SFH 4716S at or below 1A forward current are directly compatible with the SFH 4716AS without modification. Applications requiring the full 1.5A capability of the substitute part benefit from increased radiant intensity output. The forward voltage differential of 0.3V must be evaluated within the context of the application's power supply and current-limiting circuit design.

Frequently Asked Questions (FAQ)

Q: Can the SFH 4716AS directly replace the SFH 4716S in existing designs?

A: The SFH 4716AS maintains identical wavelength (860nm), package configuration (3-SMD, No Lead), mounting type (Surface Mount), viewing angle (150°), and operating temperature range (-40°C to 125°C). Direct substitution is supported for applications operating at or below 1A forward current. The forward voltage difference of 0.3V (2.9V to 3.2V) must be accommodated within the application's current-limiting circuit.

Q: What are the key differences between SFH 4716S and SFH 4716AS?

A: The primary differences are maximum forward current (1A versus 1.5A), typical forward voltage (2.9V versus 3.2V), and radiant intensity (225mW/sr @ 1A versus 300mW/sr @ 1A). The SFH 4716AS carries active product status while the SFH 4716S is obsolete. All other electrical and mechanical parameters remain identical.

Q: Does the higher radiant intensity of the SFH 4716AS affect circuit compatibility?

A: The increased radiant intensity (300mW/sr @ 1A versus 225mW/sr @ 1A) results from the substitute part's enhanced optical output characteristics. This parameter does not affect electrical circuit compatibility when forward current is maintained at or below 1A. Applications may benefit from improved optical performance without circuit modification.

Q: Are both parts packaged identically?

A: Both the SFH 4716S and SFH 4716AS utilize the same 3-SMD, No Lead package configuration. The SFH 4716AS is supplied in Tape & Reel (TR) packaging format, while the SFH 4716S was supplied in standard packaging. The physical component dimensions and footprint remain identical.

Q: What compliance certifications apply to both parts?

A: Both the SFH 4716S and SFH 4716AS are ROHS3 compliant and REACH unaffected. Both components carry Moisture Sensitivity Level (MSL) 2 with a 1-year shelf life. Both are classified under ECCN EAR99 and HTSUS 8541.41.0000.

Q: Is the SFH 4716AS suitable for applications requiring the full 1A specification of the original part?

A: The SFH 4716AS is rated for 1.5A maximum forward current, exceeding the 1A requirement of the SFH 4716S. Applications designed for 1A operation are fully supported by the substitute part's higher current rating. Current-limiting circuit design must accommodate the 0.3V forward voltage increase.
