SSL-LX3054SID Red LED T-1 Equivalent & Substitute Parts

Part Overview

The SSL-LX3054SID is a red diffused LED manufactured by Lumex Opto/Components Inc., designed for indication applications in through-hole mounting configurations. This T-1 form factor LED operates at 2.1V forward voltage with a 100mcd brightness rating and 60° viewing angle. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across different manufacturers while preserving the core functional requirements of red LED indication in T-1 through-hole applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSL-LX3054SID is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Color: Red
• Mounting Type: Through Hole
• Lens Size: T-1 form factor (3mm nominal diameter)
• Package / Case: Radial configuration
• Forward Voltage (Vf): 1.9V to 2.2V range
• Test Current: 20mA
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Optical Performance Parameters:

• Millicandela Rating: 90mcd to 330mcd acceptable
• Viewing Angle: 40° to 60° acceptable
• Wavelength - Peak: 626nm to 636nm acceptable
• Lens Transparency: Diffused or Clear acceptable

All identified substitute parts meet these mandatory criteria. Variations in brightness (mcd), viewing angle, and lens transparency represent acceptable trade-offs based on application requirements, provided electrical and mechanical compatibility is maintained.

Parameter Comparison

Engineering Selection Recommendations

HLMP-NG07 (Broadcom Limited)

This substitute maintains 60° viewing angle matching the SSL-LX3054SID and operates at 1.9V forward voltage, which is 0.2V lower than the main part. The 90.2mcd brightness is comparable to the 100mcd rating. The clear lens transparency differs from the diffused lens of the SSL-LX3054SID, affecting light distribution characteristics. Height is 6.20mm, exceeding the SSL-LX3054SID maximum of 5.25mm. All compliance certifications align. This part is suitable for applications where higher brightness concentration and increased height clearance are acceptable.

SLI-343U8R3F (Rohm Semiconductor, EXCELED™ Series)

This substitute operates at 2.2V forward voltage, 0.1V higher than the SSL-LX3054SID. Brightness is 220mcd, significantly higher than the 100mcd rating. Viewing angle is 40°, narrower than the 60° specification. Lens transparency is diffused, matching the SSL-LX3054SID. Height is 5.60mm, within acceptable mechanical envelope. All compliance certifications align. This part is suitable for applications requiring higher brightness with narrower beam concentration.

SLI-343U8RC3F (Rohm Semiconductor, EXCELED™ Series)

This substitute operates at 2.2V forward voltage with 330mcd brightness and clear lens transparency. Viewing angle is 40°. Height is 5.60mm. All compliance certifications align. This part is suitable for applications requiring maximum brightness with clear lens characteristics and narrower viewing angle.

SLI-343V8R3F (Rohm Semiconductor, EXCELED™ Series)

This substitute operates at 2.2V forward voltage with 330mcd brightness and diffused lens transparency. Viewing angle is 40°. Height is 5.40mm, the lowest among all substitutes. All compliance certifications align. This part is suitable for applications requiring maximum brightness with diffused lens and minimal height profile.

SLI-343V8RC3F (Rohm Semiconductor, EXCELED™ Series)

This substitute operates at 2.2V forward voltage with 330mcd brightness and diffused lens transparency. Viewing angle is 40°. Height is 5.60mm. All compliance certifications align. This part is suitable for applications requiring maximum brightness with diffused lens characteristics and narrower viewing angle.

All substitute parts maintain active product status, ROHS3 compliance, unlimited moisture sensitivity rating, and REACH unaffected status, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can HLMP-NG07 replace SSL-LX3054SID in all applications?

A: HLMP-NG07 is mechanically and electrically compatible as a through-hole T-1 red LED. However, it differs in three aspects: forward voltage is 1.9V versus 2.1V, lens transparency is clear versus diffused, and maximum height is 6.20mm versus 5.25mm. Applications with height constraints or requiring diffused light distribution may require circuit redesign or alternative selection.

Q: What is the primary difference between Rohm SLI-343 variants?

A: The SLI-343 series variants differ in wavelength dominant specification and lens transparency. SLI-343U8R3F and SLI-343U8RC3F operate at 620nm dominant wavelength. SLI-343V8R3F and SLI-343V8RC3F operate at 630nm dominant wavelength. The "R" designation indicates diffused lens; "RC" indicates diffused lens with red color specification. All operate at 2.2V forward voltage and 20mA test current.

Q: Is the 0.1V to 0.3V forward voltage difference between substitutes significant?

A: Forward voltage differences within the 1.9V to 2.2V range are acceptable for indication applications. However, circuit current-limiting resistor values may require adjustment. The SSL-LX3054SID at 2.1V and Rohm parts at 2.2V require minimal adjustment. HLMP-NG07 at 1.9V may require resistor recalculation to maintain 20mA test current if the circuit is voltage-sensitive.

Q: Why do Rohm substitutes have narrower 40° viewing angles compared to SSL-LX3054SID at 60°?

A: Viewing angle is determined by lens design and internal LED chip configuration. The 40° angle in Rohm parts concentrates light output, resulting in higher brightness (220mcd to 330mcd) compared to the 100mcd of the SSL-LX3054SID. Applications requiring wide-angle diffuse illumination should prioritize HLMP-NG07 or maintain the original SSL-LX3054SID.

Q: Are all substitutes available in equivalent packaging quantities?

A: Inventory levels vary by substitute. SSL-LX3054SID has 1,079 pieces in stock. HLMP-NG07 has 6,400 pieces. Rohm SLI-343 variants range from 1,545 to 25,153 pieces. Availability should be confirmed for production volume requirements.

Q: Do all substitutes meet the same compliance standards as SSL-LX3054SID?

A: Yes. All identified substitutes are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Moisture sensitivity level is 1 (unlimited) for all parts. Regulatory continuity is maintained across all substitutes.

Q: What is the mechanical compatibility consideration for PCB mounting?

A: All parts are through-hole radial configuration with compatible lead spacing. Height differences range from 5.25mm to 6.20mm. Applications with height constraints below 5.40mm should select SLI-343V8R3F. Applications with height constraints below 5.60mm should exclude HLMP-NG07.
