Key Parameters

Substitute Part Grouping Explanation

Substitution of the SFH 4716AS-FR is determined by strict alignment of the following critical parameters:

Wavelength Matching: The substitute part must operate at 860nm to maintain spectral compatibility with optical receiver systems and application-specific filtering.

Current Rating: Maximum DC forward current must be rated at 1.5A to ensure safe operation within circuit design constraints.

Viewing Angle: The 150° viewing angle is a fixed optical characteristic that must be preserved for beam pattern consistency.

Package Configuration: The 3-SMD, No Lead surface mount package ensures mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Operating Temperature Range: The -40°C to 125°C specification must be maintained for thermal environment compatibility.

Series Designation: OSLON® Black series classification ensures consistency with the original component family and performance characteristics.

The SFH 4716AS is identified as the manufacturer-recommended substitute, meeting all critical parameters while offering improved radiant intensity performance and Active product status.

Engineering Selection Recommendations

Primary Substitute: SFH 4716AS

The SFH 4716AS is the manufacturer-recommended substitute for the obsolete SFH 4716AS-FR. This part maintains full electrical and mechanical compatibility across all critical parameters including wavelength, current rating, viewing angle, operating temperature range, and package configuration.

The SFH 4716AS offers the following advantages:

Product Status: Active product status ensures long-term availability and continued manufacturer support, eliminating supply chain risk associated with obsolete components.

Compliance Certifications: Both parts maintain ROHS3 compliance and identical Moisture Sensitivity Level (MSL) ratings, ensuring regulatory and environmental compatibility.

Performance Enhancement: The substitute part delivers 300mW/sr radiant intensity compared to 224mW/sr in the original part, providing improved optical output while maintaining identical electrical specifications.

Forward Voltage Compatibility: The typical forward voltage increases from 3.15V to 3.2V, representing a 0.05V differential that falls within standard circuit design tolerances for LED driver circuits.

Packaging Availability: The SFH 4716AS is available in Tape & Reel (TR) packaging format, supporting high-volume manufacturing and automated assembly processes.

Frequently Asked Questions (FAQ)

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

A: Yes. The SFH 4716AS maintains identical electrical ratings (1.5A maximum forward current, 860nm wavelength), mechanical configuration (3-SMD, No Lead package), and thermal specifications (-40°C to 125°C operating range). The 0.05V increase in typical forward voltage is within standard circuit design margins for LED driver applications.

Q: What is the significance of the radiant intensity increase from 224mW/sr to 300mW/sr?

A: The radiant intensity specification defines the optical power output per unit solid angle at a given forward current. The 34% increase in radiant intensity in the substitute part indicates enhanced optical performance. Circuit designs must verify that optical receiver systems can accommodate this increased output without saturation or performance degradation.

Q: Why is the SFH 4716AS-FR classified as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production and support for this part number. The SFH 4716AS represents the active replacement in the product line, offering equivalent functionality with improved performance characteristics.

Q: Are there packaging differences between the two parts?

A: The SFH 4716AS-FR packaging format is not specified in the provided data. The SFH 4716AS is available in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. Confirm packaging requirements with your assembly process specifications.

Q: Do both parts meet the same regulatory and environmental standards?

A: Yes. Both the SFH 4716AS-FR and SFH 4716AS are ROHS3 compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 2 (1 Year). Both parts are classified under ECCN EAR99 and HTSUS 8541.41.0000.

Q: What is the viewing angle specification and why does it matter?

A: Both parts specify a 150° viewing angle, which defines the half-angle of the optical emission cone. This parameter is critical for applications requiring specific beam patterns and must be preserved during component substitution to maintain optical system performance.

Q: Is the OSLON® Black series designation important for substitution?

A: Yes. The OSLON® Black series designation indicates a specific product family within the ams-OSRAM portfolio with defined performance characteristics. Both the main part and substitute maintain this series classification, ensuring consistency with the original design intent.
