Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFH 4717AS A01 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package / Case: 1515 (3838 Metric) surface mount configuration
• Current - DC Forward (If) Max: 1.5A
• Mounting Type: Surface Mount
• Wavelength: 860nm (primary) or 850nm (near-infrared alternative)

Secondary Compatibility Criteria:

• Operating Temperature Range: Minimum -40°C to 125°C overlap
• Radiant Intensity (Ie) Min @ If: Equal to or greater than 630mW/sr @ 1A
• Voltage - Forward (Vf) Typical: Within acceptable circuit design parameters

Substitute parts are grouped into two categories:

Category 1 - Manufacturer Recommended (MFR Recommended): Parts from the same manufacturer (ams-OSRAM USA INC.) with identical package, current rating, and wavelength specifications. These parts maintain full electrical and mechanical compatibility.

Category 2 - Similar Manufacturer (Similar Manufacturer): Parts from alternative manufacturers with equivalent package dimensions, current ratings, and near-infrared wavelength specifications. These parts provide functional equivalence with minor parameter variations.

Engineering Selection Recommendations

SFH 4718AS A01 (MFR Recommended Substitute)

The SFH 4718AS A01 is the primary substitute for the SFH 4717AS A01. Both components are manufactured by ams-OSRAM USA INC. and share identical package dimensions (1515/3838 Metric), maximum forward current (1.5A), wavelength (860nm), viewing angle (50°), and operating temperature range (-40°C to 125°C). The SFH 4718AS A01 maintains ROHS3 compliance and MSL 2 rating identical to the original part.

Key differences include a lower typical forward voltage (2.95V versus 3.5V) and higher radiant intensity (1120mW/sr @ 1A versus 630mW/sr @ 1A). The SFH 4718AS A01 carries an "Active" product status, ensuring continued manufacturer support and availability. This part is suitable for direct replacement in existing designs without circuit modification.

AU3838A-YRR-1000MA (Similar Manufacturer Substitute)

The AU3838A-YRR-1000MA, manufactured by Solidlite, provides functional equivalence with the following considerations:

The part maintains identical package dimensions (1515/3838 Metric), maximum forward current (1.5A), and surface mount configuration. The wavelength specification of 850nm falls within the near-infrared spectrum, differing by 10nm from the original 860nm specification. The typical forward voltage (3.3V) is comparable to the original part.

The radiant intensity (500mW/sr @ 1A) is lower than the original specification (630mW/sr @ 1A), representing a 20.6% reduction in radiant output. The viewing angle is wider at 90° compared to the original 50°, affecting beam concentration characteristics. The operating temperature range (-40°C to 85°C) is narrower than the original specification, with a maximum temperature 40°C lower than the SFH 4717AS A01.

The AU3838A-YRR-1000MA carries an MSL 4 rating (72 hours) compared to MSL 2 (1 year) for the original part, requiring more stringent moisture control during storage and handling. RoHS compliance status is not specified for this part.

Selection between these substitutes depends on application-specific requirements for radiant intensity, wavelength precision, operating temperature range, and moisture sensitivity management.

Frequently Asked Questions (FAQ)

Q: Can the SFH 4718AS A01 be used as a direct replacement for the SFH 4717AS A01?

A: Yes. Both parts share identical package dimensions (1515/3838 Metric), maximum forward current (1.5A), wavelength (860nm), viewing angle (50°), and operating temperature range (-40°C to 125°C). The SFH 4718AS A01 exhibits lower forward voltage and higher radiant intensity, making it functionally compatible for direct substitution.

Q: What are the key differences between the SFH 4718AS A01 and AU3838A-YRR-1000MA?

A: Both parts share the 1515 (3838 Metric) package and 1.5A maximum forward current. The SFH 4718AS A01 operates at 860nm wavelength with 50° viewing angle and -40°C to 125°C temperature range. The AU3838A-YRR-1000MA operates at 850nm wavelength with 90° viewing angle and -40°C to 85°C temperature range. Radiant intensity differs: SFH 4718AS A01 delivers 1120mW/sr @ 1A, while AU3838A-YRR-1000MA delivers 500mW/sr @ 1A.

Q: Is the AU3838A-YRR-1000MA suitable for applications requiring the full -40°C to 125°C operating temperature range?

A: No. The AU3838A-YRR-1000MA is rated for -40°C to 85°C operation. Applications requiring operation above 85°C must use the SFH 4717AS A01 or SFH 4718AS A01.

Q: What is the significance of the MSL rating difference between these parts?

A: The SFH 4717AS A01 and SFH 4718AS A01 carry MSL 2 ratings (1 year shelf life under controlled conditions). The AU3838A-YRR-1000MA carries an MSL 4 rating (72 hours shelf life), requiring more stringent moisture control during storage, handling, and assembly processes.

Q: How does the radiant intensity difference affect application performance?

A: Radiant intensity determines the optical power output per unit solid angle. The SFH 4718AS A01 delivers 1120mW/sr @ 1A, exceeding the original SFH 4717AS A01 specification of 630mW/sr @ 1A by 77.8%. The AU3838A-YRR-1000MA delivers 500mW/sr @ 1A, which is 20.6% lower than the original specification. Applications with fixed optical receiver sensitivity may require circuit adjustment when substituting parts with significantly different radiant intensity values.

Q: Are all three parts RoHS compliant?

A: The SFH 4717AS A01 and SFH 4718AS A01 are both ROHS3 compliant. RoHS compliance status is not specified in the provided data for the AU3838A-YRR-1000MA.

Q: What is the impact of the 40° viewing angle difference between SFH 4718AS A01 and AU3838A-YRR-1000MA?

A: The SFH 4718AS A01 provides a 50° viewing angle, concentrating optical output in a narrower beam. The AU3838A-YRR-1000MA provides a 90° viewing angle, distributing optical output over a wider area. Applications requiring narrow-beam concentration should use the SFH 4718AS A01. Applications requiring wider optical distribution may benefit from the AU3838A-YRR-1000MA.

Q: Why is the SFH 4717AS A01 marked as "Not For New Designs"?

A: This designation indicates that ams-OSRAM has discontinued this component for new product development. Existing designs using this part should transition to active alternatives such as the SFH 4718AS A01 to ensure long-term availability and manufacturer support.
