SSL-LXTO46UV2C Ultraviolet Emitter Equivalent & Substitute Parts

Part Overview

The SSL-LXTO46UV2C is an ultraviolet (UV) emitter manufactured by Lumex Opto/Components Inc., operating at a wavelength of 405nm with a maximum forward current of 50mA and typical forward voltage of 3.7V. This component is housed in a TO-46-2 lens top metal can package with through-hole mounting and an 80° viewing angle. The part is classified as Active product status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when component availability is limited, inventory constraints exist, or design flexibility permits operation within alternative electrical and mechanical specifications. The SSL-LXTO46UV2C has one documented equivalent substitute based on UV emitter category parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for UV emitter components is determined by the following critical parameters:

• Wavelength: Primary functional parameter defining UV emission spectrum
• Current Rating (If Max): Maximum allowable forward current for safe operation
• Forward Voltage (Vf): Typical operating voltage for circuit design compatibility
• Package / Case Type: Physical form factor and lead configuration
• Viewing Angle: Radiation pattern and beam divergence
• Operating Temperature Range: Thermal operating limits
• Compliance Status: RoHS and REACH certifications

The MT3700W3-UV substitute operates at 370nm wavelength with 15mA maximum current, differing from the SSL-LXTO46UV2C in spectral output, current capacity, and package configuration. Substitution is valid only when application requirements permit operation at the alternative wavelength and current specifications.

Engineering Selection Recommendations

SSL-LXTO46UV2C Selection Criteria:

Use the SSL-LXTO46UV2C when applications require 405nm wavelength emission, 50mA forward current capacity, and operation across the full -40°C to 100°C temperature range. This part is RoHS3 compliant and maintains active product status with established inventory availability.

MT3700W3-UV Substitution Criteria:

The MT3700W3-UV substitute is applicable only when all of the following conditions are met:

• Application wavelength requirement permits operation at 370nm instead of 405nm
• Circuit design accommodates maximum 15mA forward current (versus 50mA)
• Operating temperature range does not exceed -20°C to 80°C
• Physical PCB layout can accommodate TO-5 package form factor instead of TO-46-2
• Wider 90° viewing angle is acceptable or beneficial for the application

Both parts maintain RoHS compliance, unlimited MSL rating, and REACH unaffected status. The substitute part is RoHS compliant (non-version-specific designation) while the main part specifies RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can MT3700W3-UV directly replace SSL-LXTO46UV2C without circuit modification?

A: No. The MT3700W3-UV operates at 370nm wavelength versus 405nm, has a maximum current rating of 15mA versus 50mA, and uses a different package form factor (TO-5 versus TO-46-2). Circuit redesign is required for wavelength-dependent applications, and current-limiting circuitry must be adjusted for the lower 15mA rating.

Q: What is the primary difference between these two UV emitters?

A: The primary differences are wavelength (405nm versus 370nm), maximum forward current (50mA versus 15mA), package type (TO-46-2 versus TO-5), and operating temperature range (-40 to 100°C versus -20 to 80°C). These differences make substitution application-dependent.

Q: Are both parts RoHS compliant?

A: Yes. The SSL-LXTO46UV2C is RoHS3 compliant, and the MT3700W3-UV is RoHS compliant. Both meet RoHS requirements; the main part specifies the newer RoHS3 standard.

Q: What are the package compatibility considerations?

A: The SSL-LXTO46UV2C uses TO-46-2 lens top metal can packaging, while the MT3700W3-UV uses TO-5 variant packaging. These are different physical form factors requiring PCB layout modifications, including different lead spacing and mounting hole positioning.

Q: Can the MT3700W3-UV operate at the same current levels as the SSL-LXTO46UV2C?

A: No. The MT3700W3-UV has a maximum forward current rating of 15mA, while the SSL-LXTO46UV2C is rated for 50mA. Operating the substitute at higher currents exceeds its electrical specifications and will cause component failure.

Q: What temperature range limitations apply to the substitute part?

A: The MT3700W3-UV operates from -20°C to 80°C, which is narrower than the SSL-LXTO46UV2C range of -40°C to 100°C. Applications requiring operation below -20°C or above 80°C cannot use the substitute part.

Q: Is the viewing angle difference significant?

A: The SSL-LXTO46UV2C has an 80° viewing angle, while the MT3700W3-UV has a 90° viewing angle. The 10° difference results in a wider radiation pattern for the substitute. Applications with specific beam divergence requirements must account for this difference.
