Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the SSL-LX5093LIT is determined by the following critical parameters: color (red), mounting type (through hole), package configuration (radial), lens size (5mm T-1 3/4 or equivalent), and forward voltage range compatible with standard 2V indicator circuits. All substitute parts maintain red color output and through-hole radial mounting.

The substitute parts are grouped based on the following allowed parameters:

• Color: Red (all substitutes)
• Mounting Type: Through Hole (all substitutes)
• Package / Case: Radial (all substitutes)
• Lens Style: Round with Domed Top (all substitutes)
• Lens Size: 5mm T-1 3/4 or 4.90mm equivalent diameter
• Forward Voltage (Vf): 1.7V to 2.1V range
• Current - Test: 1mA to 20mA range
• Wavelength - Peak: 627nm to 660nm range (red spectrum)
• RoHS Status: ROHS3 Compliant (all substitutes)
• Moisture Sensitivity Level: 1 (Unlimited) (all substitutes)

Substitutes differ in millicandela rating, viewing angle, and specific wavelength characteristics, which may affect brightness and directional light distribution in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the SSL-LX5093LIT. Selection among substitutes depends on circuit-specific electrical requirements and optical performance needs.

151051SS04000 (Würth Elektronik): Highest brightness at 250mcd with 2.1V forward voltage and 40° viewing angle. Suitable for applications requiring increased luminous intensity within the 20mA test current specification.

WP7113IT (Kingbright): Matches 2V forward voltage and 20mA test current of the SSL-LX5093LIT with 100mcd output. Narrower 20° viewing angle provides more directional light output. Identical height specification (8.60mm) ensures mechanical compatibility.

SLR-56VC3F (Rohm Semiconductor): Operates at 2V forward voltage with reduced 10mA test current, delivering 25mcd output. Wider 40° viewing angle with 8.90mm height. Suitable for low-power indicator applications.

HLMP-D155 (Broadcom Limited): Lowest forward voltage at 1.7V with minimal 1mA test current and 10mcd output. Taller profile at 12.44mm may require mechanical clearance verification. Suitable for ultra-low-power indicator circuits.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX5093LIT be directly replaced with any of these substitute parts?

A: Direct replacement depends on circuit design. All substitutes share red color, through-hole radial mounting, and 5mm lens form factor. However, forward voltage, test current, and brightness differ. Circuit resistor values may require adjustment to accommodate different Vf and current specifications.

Q: Which substitute offers the closest electrical match to the SSL-LX5093LIT?

A: The WP7113IT (Kingbright) provides the closest match with identical 2V forward voltage and 20mA test current. Height specification is also identical at 8.60mm, minimizing mechanical redesign requirements.

Q: What is the brightness difference between the SSL-LX5093LIT and substitute parts?

A: The SSL-LX5093LIT delivers 200mcd. The 151051SS04000 offers higher brightness at 250mcd. The WP7113IT provides 100mcd (50% reduction). The SLR-56VC3F and HLMP-D155 deliver significantly lower brightness at 25mcd and 10mcd respectively, suitable only for low-intensity indicator applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the SSL-LX5093LIT compliance profile.

Q: Does lens transparency affect substitution compatibility?

A: The SSL-LX5093LIT specifies clear lens transparency. Most substitutes maintain clear transparency. The 151051SS04000 does not specify lens transparency in the provided data. Verify lens transparency requirements for your specific application before selection.

Q: What viewing angle differences exist among substitutes?

A: The SSL-LX5093LIT has a 30° viewing angle. The 151051SS04000 and SLR-56VC3F offer wider 40° angles for broader light distribution. The WP7113IT provides a narrower 20° angle for more directional output. The HLMP-D155 specifies 24°. Application requirements determine optimal viewing angle selection.

Q: Can the HLMP-D155 be used in circuits designed for the SSL-LX5093LIT?

A: The HLMP-D155 operates at 1.7V forward voltage and 1mA test current, significantly different from the SSL-LX5093LIT's 2V and 20mA specifications. Circuit redesign is required. The 12.44mm height also exceeds other options, requiring mechanical clearance verification. Use only in applications specifically designed for low-power, low-brightness indicators.

Q: What is the impact of different wavelength peaks on color perception?

A: All substitute parts emit red light within the 627nm to 660nm range. The SSL-LX5093LIT peaks at 635nm. Wavelength variations within this range produce visually similar red color output. Specific wavelength selection depends on color matching requirements in multi-LED indicator arrays.
