Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSF-LXH475GGYYD is determined by the following critical parameters:

Electrical Compatibility:

• Configuration: 4 High (Green x2, Yellow x2)
• Current Rating: 20mA
• Voltage Rating: 2.1V to 2.2V range
• Wavelength: 565nm (Green), 585nm (Yellow)
• Viewing Angle: 60°

Mechanical Compatibility:

• Lens Size: 3mm diameter
• Lens Style: Round with Domed Top
• Lens Type: Diffused

Regulatory Compliance:

• RoHS3 Compliant
• MSL Rating: 1 (Unlimited)

The identified substitute part 5680102233F from Dialight maintains electrical equivalence in configuration, current, voltage, wavelength, and viewing angle. The primary difference is mounting type: the substitute features right-angle through-hole mounting versus the original straight configuration.

Parameter Comparison

Engineering Selection Recommendations

The 5680102233F from Dialight is an active equivalent substitute for the obsolete SSF-LXH475GGYYD. Both components share identical electrical specifications including configuration, current rating, voltage rating, wavelength, and viewing angle. Both maintain ROHS3 compliance and MSL Rating 1 status.

The primary design consideration is the mounting orientation difference: the Dialight part features right-angle through-hole mounting, while the original Lumex part uses straight through-hole mounting. This difference requires PCB layout modification to accommodate the alternate mounting geometry.

The Dialight substitute exhibits lower millicandela ratings (12.6mcd Green, 10mcd Yellow versus 20mcd Green, 30mcd Yellow in the original). Applications requiring the original brightness levels must evaluate whether the reduced luminous intensity is acceptable for the intended circuit board indicator function.

Frequently Asked Questions (FAQ)

Q: Can the 5680102233F directly replace the SSF-LXH475GGYYD without PCB modification?

A: No. The 5680102233F features right-angle through-hole mounting, while the SSF-LXH475GGYYD uses straight through-hole mounting. PCB footprint modification is required.

Q: Are the electrical specifications identical between these parts?

A: The electrical specifications are equivalent in configuration (4 High), current (20mA), voltage (2.1V to 2.2V), wavelength (565nm/585nm), and viewing angle (60°). The millicandela ratings differ.

Q: Does the brightness difference affect compatibility?

A: The 5680102233F provides lower luminous intensity (12.6mcd Green, 10mcd Yellow) compared to the original (20mcd Green, 30mcd Yellow). Applications must confirm whether reduced brightness is acceptable for the intended indicator function.

Q: Are both parts RoHS compliant?

A: Yes. Both SSF-LXH475GGYYD and 5680102233F are ROHS3 compliant with MSL Rating 1 (Unlimited).

Q: What is the lens size difference between these parts?

A: Both parts feature 3mm diameter round domed diffused lenses. The SSF-LXH475GGYYD is designated T-1 form factor, while the 5680102233F specifies 3.00mm diameter.

Q: Is the 5680102233F available in active production?

A: Yes. The 5680102233F is classified as active product status, ensuring ongoing availability and supply chain continuity.
