Parameter Comparison

Engineering Selection Recommendations

The SFH 4715AS is the direct substitute for the obsolete SFH 4715AS-FR. Both components are manufactured by ams-OSRAM USA INC. within the OSLON® Black series and maintain identical primary electrical and mechanical specifications.

The SFH 4715AS offers the following advantages for new designs and production continuity:

Product Status: The SFH 4715AS maintains Active product status, ensuring long-term availability and supply chain stability compared to the Obsolete SFH 4715AS-FR.

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

Performance Characteristics: The SFH 4715AS provides enhanced radiant intensity (780mW/sr @ 1A versus 710mW/sr @ 1A) and expanded viewing angle (90° versus 80°), delivering improved optical performance within the same package footprint.

Electrical Compatibility: Forward voltage specification increases marginally from 3.15V to 3.2V, representing a 0.05V differential that falls within standard circuit design tolerances for 860nm infrared emitter applications.

Frequently Asked Questions (FAQ)

Q: Can the SFH 4715AS directly replace the SFH 4715AS-FR in existing designs?

A: Yes. Both components share identical wavelength (860nm), maximum forward current (1.5A), operating temperature range (-40°C ~ 125°C), mounting type (Surface Mount), and package configuration (3-SMD, No Lead). The SFH 4715AS is the manufacturer-recommended substitute.

Q: What are the differences between the SFH 4715AS-FR and SFH 4715AS?

A: The primary differences are: (1) Product Status—SFH 4715AS-FR is Obsolete while SFH 4715AS is Active; (2) Forward Voltage—3.15V versus 3.2V; (3) Radiant Intensity—710mW/sr versus 780mW/sr @ 1A; (4) Viewing Angle—80° versus 90°. All other specifications remain identical.

Q: Are there packaging differences between these parts?

A: Both components utilize identical 3-SMD, No Lead surface mount packages. The SFH 4715AS is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexible procurement options for production environments.

Q: Does the increased radiant intensity of the SFH 4715AS affect circuit design?

A: The SFH 4715AS delivers 70mW/sr additional radiant intensity at 1A forward current. Circuit designs must account for this enhanced optical output to prevent over-illumination in sensitive applications. Forward current limiting and optical filtering should be evaluated based on specific application requirements.

Q: Is the 0.05V forward voltage increase significant?

A: The forward voltage increase from 3.15V to 3.2V represents a 1.6% variance. This falls within standard design tolerances for infrared emitter applications and does not require circuit redesign in most implementations. Verify compliance with specific power supply and current limiting circuit specifications.

Q: What is the significance of the expanded 90° viewing angle?

A: The SFH 4715AS provides a 10° wider viewing angle compared to the SFH 4715AS-FR. This expanded angular distribution may affect optical system design and beam concentration characteristics. Applications requiring precise beam geometry should evaluate this parameter against specific optical requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the SFH 4715AS-FR and SFH 4715AS maintain ROHS3 compliance status, ensuring equivalent environmental and regulatory compliance for applications subject to RoHS directives.

Q: What is the Moisture Sensitivity Level (MSL) for these components?

A: Both components carry MSL rating of 2 (1 Year), indicating identical moisture handling and storage requirements. Standard moisture control procedures during assembly and storage apply to both parts.
