SFH 4655-UV Equivalent & Substitute Parts

Part Overview

The SFH 4655-UV is an Infrared (IR) Emitter manufactured by ams-OSRAM USA INC., operating at 860nm wavelength with a maximum forward current of 100mA and typical forward voltage of 1.5V. This component is classified as a Power TOPLED® series device and is currently in Active product status. The SFH 4655-UV is packaged as a 2-SMD, No Lead surface mount component with a 30° viewing angle and radiant intensity of 40mW/sr at 100mA.

Substitute parts are identified when equivalent electrical performance parameters are met within the same wavelength specification and current rating, while accounting for differences in mechanical packaging and mounting technology.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFH 4655-UV are identified based on the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Wavelength: 860nm (exact match required)
• Maximum Forward Current (If): 100mA (exact match required)
• Typical Forward Voltage (Vf): 1.5V (exact match required)
• Operating Temperature Range: -40°C to 100°C (exact match required)

Mechanical Compatibility Considerations:

• Mounting Type: Surface Mount vs. Through Hole (determines PCB integration method)
• Package / Case: 2-SMD, No Lead vs. Radial (affects footprint and assembly process)
• Viewing Angle: Variation acceptable within application-specific requirements

Compliance & Status:

• Product Status: Active (current manufacturing availability)
• RoHS Status: ROHS3 Compliant (regulatory requirement match)
• REACH Status: REACH Unaffected (regulatory requirement match)

The SFH 4350 meets all electrical equivalence criteria but differs in mechanical packaging (Through Hole Radial vs. Surface Mount 2-SMD) and radiant intensity specification (200mW/sr vs. 40mW/sr).

Parameter Comparison

Engineering Selection Recommendations

SFH 4655-UV Primary Application: The SFH 4655-UV is specified for surface mount assembly processes requiring a 2-SMD, No Lead package format. This component is suitable for applications where PCB real estate is constrained and automated pick-and-place assembly is employed.

SFH 4350 Substitution Conditions: The SFH 4350 provides electrical equivalence in wavelength, forward current, and forward voltage specifications. However, substitution requires the following conditions to be met:

1. PCB design must accommodate Through Hole Radial mounting instead of surface mount 2-SMD, No Lead
2. Assembly process must support radial lead insertion and wave soldering or manual soldering techniques
3. Application must tolerate the increased radiant intensity (200mW/sr vs. 40mW/sr at 100mA)
4. Application must tolerate the reduced viewing angle (26° vs. 30°)

Both components maintain Active product status, ROHS3 compliance, and REACH Unaffected regulatory standing, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the SFH 4350 be used as a direct replacement for the SFH 4655-UV in an existing surface mount PCB design?

A: No. The SFH 4350 is a Through Hole Radial component, while the SFH 4655-UV is a Surface Mount 2-SMD, No Lead component. Direct PCB substitution is not possible without redesign of the footprint and assembly process modification.

Q: What are the electrical differences between these two parts?

A: Both components share identical wavelength (860nm), maximum forward current (100mA), and typical forward voltage (1.5V) specifications. The primary electrical difference is radiant intensity: the SFH 4350 provides 200mW/sr at 100mA, while the SFH 4655-UV provides 40mW/sr at 100mA.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the SFH 4655-UV and SFH 4350 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards for electronic components.

Q: What is the viewing angle difference, and does it affect substitution?

A: The SFH 4655-UV has a 30° viewing angle, while the SFH 4350 has a 26° viewing angle. This 4° difference may affect light distribution characteristics in applications requiring specific beam geometry. Application requirements must be evaluated to determine if this difference is acceptable.

Q: Are both components currently in production?

A: Yes. Both the SFH 4655-UV and SFH 4350 maintain Active product status with ams-OSRAM USA INC., indicating current manufacturing availability.

Q: What packaging format differences exist between these parts?

A: The SFH 4655-UV is supplied in Tape & Reel (TR) packaging for automated surface mount assembly. The SFH 4350 is supplied in Bulk packaging for manual or semi-automated Through Hole assembly processes.
