Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSF-LXH475SUGD is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Configuration: 4 High (quad LED arrangement)
• Color: Green (x 4)
• Current Rating: 20mA
• Voltage Rating: Within acceptable tolerance range
• Wavelength: Green spectrum (565nm–574nm range)

Mechanical Compatibility Parameters:

• Lens Size: 3mm, T-1 form factor
• Lens Style: Round with Domed Top
• Mounting: Through Hole compatibility

Compliance Parameters:

• RoHS3 Compliance
• Moisture Sensitivity Level 1
• REACH Unaffected status

The substitute part 5682232222F meets these core substitution criteria with allowable variations in brightness (millicandela rating) and viewing angle, which do not prevent functional equivalence in circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

For SSF-LXH475SUGD Replacement:

The 5682232222F from Dialight qualifies as a functional equivalent based on matching electrical configuration, current rating, and compliance certifications. Both components are ROHS3 compliant with MSL 1 rating and REACH unaffected status, ensuring regulatory alignment.

Key Considerations:

1. Product Status: The substitute part 5682232222F carries Active product status, ensuring continued availability and supply chain stability compared to the Obsolete SSF-LXH475SUGD.

2. Brightness Differential: The substitute delivers 50mcd versus the original 100mcd. This reduction is acceptable in circuit board indicator applications where the LED serves as a status indicator rather than a light source. Verify that the reduced brightness meets the specific application's visibility requirements.

3. Mounting Configuration: The 5682232222F features a right-angle through-hole mount, whereas the SSF-LXH475SUGD uses standard through-hole mounting. PCB layout and component placement must be verified to accommodate the right-angle lead configuration.

4. Viewing Angle: The substitute provides a 45° viewing angle compared to the original 60°. This narrower angle is suitable for fixed-position indicator applications but may limit visibility from oblique angles.

5. Lens Characteristics: The substitute uses a tinted lens versus the diffused lens of the original. Both provide adequate light diffusion for indicator purposes, though the tinted lens may produce a slightly different color appearance.

Frequently Asked Questions (FAQ)

Q: Can the 5682232222F directly replace the SSF-LXH475SUGD without PCB modifications?

A: The 5682232222F features a right-angle mounting configuration, while the SSF-LXH475SUGD uses standard through-hole mounting. PCB layout verification is required. If the original design uses vertical mounting, the right-angle configuration of the substitute will not fit without mechanical adaptation or PCB redesign.

Q: Will the reduced brightness of the 5682232222F (50mcd vs. 100mcd) affect circuit board indicator visibility?

A: The 50mcd brightness of the substitute is sufficient for standard circuit board indicator applications. Visibility depends on ambient lighting conditions and viewing distance. Evaluate the specific application environment to confirm adequacy.

Q: Are there voltage compatibility concerns between 2.2V and 2.1V ratings?

A: The 0.1V difference is within acceptable tolerance for LED circuit designs. Standard current-limiting resistor calculations will accommodate this minor voltage variance without circuit modification.

Q: Does the tinted lens of the 5682232222F produce a different color than the diffused lens of the SSF-LXH475SUGD?

A: Both components emit green light within the standard green spectrum (565nm–574nm). The tinted lens may produce a slightly different visual appearance compared to the diffused lens, but both are suitable for green indicator applications.

Q: What is the impact of the narrower 45° viewing angle on the substitute part?

A: The 45° viewing angle is narrower than the original 60°. This is acceptable for fixed-position indicators where the LED is viewed from a consistent angle. Applications requiring wide-angle visibility should evaluate this parameter against specific requirements.

Q: Are both parts compliant with current regulatory standards?

A: Both the SSF-LXH475SUGD and 5682232222F are ROHS3 compliant, REACH unaffected, and carry MSL 1 rating. Both meet current regulatory requirements for electronic component use.
