SSL-DSP5093SYC Yellow LED T-1 3/4 Through Hole Equivalent & Substitute Parts

Part Overview

The SSL-DSP5093SYC is a yellow LED indication component manufactured by Lumex Opto/Components Inc., designed for through-hole mounting applications. This discrete 2V radial LED features a 5mm T-1 3/4 clear lens with 2500mcd brightness rating and 30° viewing angle. The product is classified as obsolete, necessitating identification of active equivalent and substitute parts that maintain functional compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSL-DSP5093SYC is determined by strict alignment with the following critical parameters:

Primary Compatibility Criteria:

• Color: Yellow
• Lens Size: 5mm, T-1 3/4
• Lens Style: Round with Domed Top
• Lens Transparency: Clear
• Mounting Type: Through Hole
• Package / Case: Radial
• Voltage - Forward (Vf) (Typ): 2V (±0.1V tolerance acceptable)
• Current - Test: 20mA
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Secondary Parameters (Allowable Variation):

• Millicandela Rating: 2500mcd baseline; substitutes with 2890mcd to 5200mcd are acceptable for indication applications
• Viewing Angle: 30° baseline; narrower angles (20°) acceptable; wider angles require application verification
• Height (Max): 8.60mm baseline; variation up to 8.85mm acceptable for standard through-hole PCB mounting
• Wavelength - Peak: 590nm baseline; 591nm acceptable within yellow LED spectrum

The identified substitute parts SLI-570YT3F and XLM2CYK14W meet all primary compatibility criteria and fall within acceptable secondary parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

SLI-570YT3F (Rohm Semiconductor): This substitute is an active product with ROHS3 compliance and REACH unaffected status. The forward voltage of 2.1V represents a 0.1V increase from the main part, which is within acceptable tolerance for standard LED indication circuits. The 5200mcd brightness rating provides enhanced luminous intensity compared to the 2500mcd baseline. The 20° viewing angle is narrower than the original 30°, resulting in more concentrated light output. Height variation of 8.85mm (0.25mm increase) remains compatible with standard through-hole PCB mounting. This substitute is suitable for applications where increased brightness is beneficial or neutral.

XLM2CYK14W (SunLED): This substitute is an active product with ROHS3 compliance and REACH unaffected status. The forward voltage of 2V matches the main part exactly. The 2890mcd brightness rating provides a modest increase from the 2500mcd baseline. The 30° viewing angle matches the original specification. The height of 8.60mm is identical to the main part. This substitute provides the closest parametric alignment to the SSL-DSP5093SYC and is suitable for direct replacement in existing designs.

Both substitutes maintain compliance with regulatory requirements (ROHS3, REACH, EAR99, HTSUS classification) and moisture sensitivity level specifications.

Frequently Asked Questions (FAQ)

Q: Can SLI-570YT3F be used as a direct replacement for SSL-DSP5093SYC?

A: SLI-570YT3F is functionally compatible with SSL-DSP5093SYC for yellow LED indication applications. The 0.1V forward voltage increase (2.1V vs. 2V) is within standard tolerance for LED circuits. The narrower 20° viewing angle concentrates light output compared to the original 30°. The 0.25mm height increase (8.85mm vs. 8.60mm) does not affect through-hole mounting compatibility. The higher brightness (5200mcd vs. 2500mcd) is suitable for indication applications.

Q: Can XLM2CYK14W be used as a direct replacement for SSL-DSP5093SYC?

A: XLM2CYK14W is functionally compatible with SSL-DSP5093SYC for yellow LED indication applications. The forward voltage (2V), viewing angle (30°), and height (8.60mm) match the original specifications exactly. The brightness increase (2890mcd vs. 2500mcd) is modest and suitable for indication applications. This substitute provides the closest parametric alignment.

Q: What are the key differences between the two substitute parts?

A: SLI-570YT3F features higher brightness (5200mcd) and a narrower viewing angle (20°), making it suitable for applications requiring concentrated light output. XLM2CYK14W provides closer parametric matching with identical forward voltage, viewing angle, and height, making it suitable for direct replacement in existing designs. Both are active products with full compliance certifications.

Q: Are there any circuit design considerations when substituting these parts?

A: The forward voltage difference in SLI-570YT3F (2.1V vs. 2V) may require minor current-limiting resistor adjustment in the LED circuit. The brightness differences between substitutes do not require circuit modification but may affect visual indication intensity. All three parts operate at 20mA test current and are compatible with standard LED indication circuits.

Q: Do the substitute parts have the same package and mounting compatibility?

A: All three parts feature identical package specifications: 5mm T-1 3/4 radial through-hole mounting with round domed clear lens. Height variations (8.60mm to 8.85mm) are within standard PCB mounting tolerances. No mechanical redesign is required for substitution.

Q: What compliance certifications apply to the substitute parts?

A: Both SLI-570YT3F and XLM2CYK14W are ROHS3 compliant, REACH unaffected, classified as EAR99, and carry HTSUS code 8541.41.0000. Moisture sensitivity level is 1 (Unlimited) for both substitutes, matching the original part specification.
