Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFH 4650-UV R33-Z is determined by the following critical parameters:

Primary Matching Criteria:

• Wavelength: 860nm (infrared spectrum alignment)
• Type: Infrared (IR) Emitter
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

Secondary Compatibility Factors:

• Current rating compatibility within application design limits
• Forward voltage tolerance within circuit design specifications
• Radiant intensity performance at rated current
• Operating temperature range coverage
• Package form factor and footprint considerations

The SFH 4059S qualifies as a substitute based on matching wavelength (860nm), infrared emitter type, surface mount capability, and ROHS3 compliance. Differences in current rating (50mA vs. 100mA), forward voltage (3.45V vs. 1.5V), package geometry (1206 vs. 2-SMD No Lead), and operating temperature maximum (85°C vs. 100°C) require circuit-level evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

SFH 4650-UV R33-Z Selection Criteria:

• Applications requiring maximum forward current of 100mA
• Low forward voltage operation (1.5V typical)
• Narrow viewing angle requirement (24°)
• Extended operating temperature range to 100°C
• Compact 2-SMD No Lead package geometry
• Reduced moisture sensitivity (MSL 2)
• Active product status with established supply chain

SFH 4059S Selection Criteria:

• Applications limited to 50mA maximum forward current
• Higher forward voltage tolerance (3.45V typical)
• Wider viewing angle requirement (30°)
• Operating temperature range limited to 85°C maximum
• Standard 1206 package footprint
• Higher moisture sensitivity (MSL 3)
• Active product status with higher inventory availability (10396 units)

Both parts maintain ROHS3 compliance and REACH unaffected status. Selection between these components depends on circuit design specifications for current, voltage, thermal environment, and package constraints.

Frequently Asked Questions (FAQ)

Q: Can the SFH 4059S directly replace the SFH 4650-UV R33-Z in existing designs?

A: Direct replacement requires circuit-level evaluation. The SFH 4059S operates at 3.45V forward voltage compared to 1.5V for the SFH 4650-UV R33-Z, necessitating current-limiting resistor recalculation. The maximum current rating of 50mA versus 100mA may impact radiant intensity output. Package geometry differs (1206 vs. 2-SMD No Lead), requiring PCB footprint modification.

Q: What are the wavelength compatibility requirements?

A: Both parts operate at 860nm wavelength, ensuring spectral compatibility for infrared detection and transmission applications. Wavelength matching is a primary substitution criterion for IR emitter components.

Q: How do the viewing angles differ between these parts?

A: The SFH 4650-UV R33-Z provides a 24° viewing angle, while the SFH 4059S offers a 30° viewing angle. Applications requiring narrow beam concentration should prioritize the SFH 4650-UV R33-Z. Applications requiring wider light distribution can utilize the SFH 4059S.

Q: What is the impact of different operating temperature ranges?

A: The SFH 4650-UV R33-Z operates from -40°C to 100°C, while the SFH 4059S operates from -40°C to 85°C. Applications requiring operation above 85°C must use the SFH 4650-UV R33-Z. The SFH 4059S is suitable for applications within the -40°C to 85°C range.

Q: How do moisture sensitivity levels affect component handling?

A: The SFH 4650-UV R33-Z has MSL 2 (1 Year floor life), while the SFH 4059S has MSL 3 (168 Hours floor life). MSL 3 components require more stringent moisture control during storage and assembly. The SFH 4650-UV R33-Z allows extended shelf life without baking procedures.

Q: Are both parts RoHS compliant?

A: Yes, both the SFH 4650-UV R33-Z and SFH 4059S are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for commercial and industrial applications.
