Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFH 4715A-CBDA is determined by the following critical parameters:

• Package / Case: 3-SMD, No Lead (physical and electrical compatibility)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Type: Infrared (IR) Emitter (functional category)
• Viewing Angle: 90° (optical performance requirement)
• Wavelength Range: 860nm nominal (application-specific requirement)
• Voltage - Forward (Vf): 1.65V typical (circuit design compatibility)
• Current - DC Forward (If): 2A maximum (power handling capability)
• Radiant Intensity (Ie): 320mW/sr @ 1A (optical output specification)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

The identified substitute part 15435394A9040 (Würth Elektronik WL-SIQW) shares the same package type, mounting method, and general IR emitter classification. However, variations exist in wavelength (940nm vs. 860nm), forward voltage (1.7V vs. 1.65V), maximum current (3A vs. 2A), and operating temperature range (-40°C ~ 85°C vs. -40°C ~ 100°C).

Parameter Comparison

Engineering Selection Recommendations

Both the SFH 4715A-CBDA and 15435394A9040 are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts depends on application-specific wavelength requirements and operating environment constraints.

The SFH 4715A-CBDA operates across a wider temperature range (-40°C ~ 100°C) compared to the 15435394A9040 (-40°C ~ 85°C). Applications requiring operation above 85°C must use the SFH 4715A-CBDA.

The wavelength difference (860nm vs. 940nm) is application-critical. The 860nm wavelength of the SFH 4715A-CBDA is suitable for specific IR sensing and transmission applications, while the 940nm wavelength of the 15435394A9040 serves different spectral requirements. Wavelength selection cannot be interchanged without application validation.

Both parts share identical package specifications (3-SMD, No Lead) and mounting type (Surface Mount), ensuring PCB layout compatibility. The 15435394A9040 offers higher maximum current capability (3A vs. 2A) and slightly higher radiant intensity (350mW/sr vs. 320mW/sr), which may provide design flexibility in current-limited applications.

Frequently Asked Questions (FAQ)

Q: Can the 15435394A9040 directly replace the SFH 4715A-CBDA in all applications?

A: Direct replacement is not universal. While both parts share the same package (3-SMD, No Lead) and mounting type (Surface Mount), the wavelength difference (860nm vs. 940nm) makes them suitable for different applications. Wavelength-dependent applications require the specific wavelength specified in the original design.

Q: What are the key differences between these two IR emitters?

A: The primary differences are wavelength (860nm vs. 940nm), forward voltage (1.65V vs. 1.7V), maximum current (2A vs. 3A), and operating temperature range (-40°C ~ 100°C vs. -40°C ~ 85°C). The SFH 4715A-CBDA supports higher temperature operation.

Q: Are both parts RoHS compliant?

A: Yes, both the SFH 4715A-CBDA and 15435394A9040 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

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

A: The 90° viewing angle indicates the half-angle of the radiation pattern. Both parts share this specification, ensuring equivalent optical beam characteristics for applications requiring this specific angular distribution.

Q: Can I use the 15435394A9040 in a temperature-critical application requiring operation above 85°C?

A: No. The 15435394A9040 is rated for -40°C ~ 85°C operation. For applications requiring operation above 85°C, the SFH 4715A-CBDA with its -40°C ~ 100°C rating must be used.

Q: How do the radiant intensity specifications compare?

A: The SFH 4715A-CBDA delivers 320mW/sr @ 1A, while the 15435394A9040 delivers 350mW/sr @ 1A (Typ). The higher radiant intensity of the substitute part may provide additional optical output margin in applications where this is beneficial.
