SSL-LX5093HD Red Diffused LED T-1 3/4 Through Hole Equivalent & Substitute Parts

Part Overview

The SSL-LX5093HD is a red diffused LED indicator manufactured by Lumex Opto/Components Inc., designed for discrete red light indication applications in through-hole mounting configurations. This component operates at a forward voltage of 2.25V with a test current of 20mA and delivers 6 millicandela of luminous intensity with a 30-degree viewing angle. The part is classified as obsolete, necessitating identification of active equivalent and substitute components that maintain functional compatibility within red LED indication circuits. Substitute parts must preserve the core electrical characteristics (forward voltage, test current, mounting type) and mechanical form factor (T-1 3/4 through-hole radial package) to ensure direct circuit compatibility.

Engineering Selection Recommendations

MFR Recommended Substitute:

The SSL-LX5093ID from Lumex Opto/Components Inc. is the primary recommended substitute. This part maintains the same manufacturer lineage (base product number SSL-LX5093) and is classified as Active with high inventory availability (54,205 pieces). The SSL-LX5093ID operates at 2.0V forward voltage (within acceptable tolerance of the original 2.25V specification) and maintains the 20mA test current requirement. The increased millicandela rating (40mcd versus 6mcd) and wider viewing angle (60° versus 30°) provide enhanced optical performance. This part is ROHS3 compliant and carries MSL Level 1 rating, matching the original component's regulatory and handling requirements.

Alternative Substitutes by Application Requirements:

For applications requiring luminous intensity matching or exceeding the original 6mcd specification, the Everlight Electronics 1383SDRD/S530-A3 (320mcd) or 333-2SDRD/S530-A3 (160mcd) are suitable. Both operate at 2.0V with 20mA test current and maintain the 5mm diffused red lens configuration. These parts are Active with ROHS3 compliance.

For applications with lower current budgets or reduced brightness requirements, the Dialight 5219320F operates at 1.8V with only 2mA test current and delivers 2mcd. This part is suitable for low-power indicator circuits where the original 20mA specification cannot be accommodated.

For applications requiring high brightness with standard 20mA operation, the Dialight 5219672F delivers 60mcd at 2.0V with 20mA test current and 60-degree viewing angle, providing enhanced visibility compared to the original part.

The Broadcom HLMP-3301 series (D0001, F0001, F00DD variants) operates at 1.9V with 10mA test current. These parts are suitable for circuits designed for reduced current consumption. The F00DD variant offers the highest inventory availability (43,381 pieces) among all substitutes.

All recommended substitutes maintain through-hole radial mounting in 5mm T-1 3/4 form factor, ensuring mechanical compatibility with existing PCB designs. Selection should be verified against specific circuit current budgets, brightness requirements, and viewing angle specifications.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX5093ID directly replace SSL-LX5093HD without circuit modification?

A: The SSL-LX5093ID is mechanically and functionally compatible for direct substitution in most applications. The forward voltage difference (2.0V versus 2.25V) is within typical LED tolerance ranges and will not require circuit redesign. However, the increased brightness (40mcd versus 6mcd) should be verified against the application's optical requirements to ensure the indicator does not exceed desired brightness levels.

Q: What is the primary difference between MFR Recommended and Similar substitutes?

A: MFR Recommended substitutes (SSL-LX5093ID) originate from the same manufacturer as the original part and share the same base product number, ensuring design continuity and manufacturer support. Similar substitutes from Everlight, Dialight, and Broadcom are functionally equivalent but from alternative manufacturers. Both categories meet all critical electrical and mechanical parameters.

Q: Are all listed substitutes RoHS3 compliant?

A: Yes. All substitute parts listed in this reference maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) rating, matching the original SSL-LX5093HD specifications. This ensures regulatory compatibility for applications subject to RoHS directives.

Q: Which substitute should be selected for a low-power application?

A: The Dialight 5219320F operates at 1.8V with only 2mA test current, making it suitable for battery-powered or ultra-low-power indicator circuits. The Broadcom HLMP-3301 series (operating at 1.9V with 10mA) provides a mid-range option between the original 20mA specification and the 2mA Dialight part.

Q: Can substitutes with different viewing angles be used interchangeably?

A: Viewing angle substitution depends on application requirements. The original SSL-LX5093HD has a 30-degree viewing angle. Substitutes with wider viewing angles (60°) such as SSL-LX5093ID, 5219672F, and HLMP-3301 series provide broader light distribution. Substitutes with matching 30-degree angles (1383SDRD/S530-A3, 333-2SDRD/S530-A3) maintain the original directional characteristics. Selection should align with the intended viewing geometry of the application.

Q: What is the significance of wavelength differences between substitutes?

A: The original SSL-LX5093HD specifies 700nm peak wavelength, which is deep red. Substitutes range from 623nm to 700nm, all within the red spectrum. Wavelength differences may affect perceived color intensity and hue. For applications where specific color matching is critical (such as standardized indicator panels), wavelength alignment should be verified. For general red indication purposes, the 635nm to 650nm range of most substitutes is functionally equivalent.

Q: Are there inventory considerations when selecting a substitute?

A: Yes. The SSL-LX5093ID offers the highest inventory availability (54,205 pieces), ensuring supply continuity. The Broadcom HLMP-3301-F00DD variant also provides substantial inventory (43,381 pieces). For applications requiring immediate availability, these options are preferred. Everlight and Dialight alternatives offer moderate inventory levels (800–2,600 pieces range).

Q: How should height differences be evaluated for PCB clearance?

A: The original SSL-LX5093HD specifies 8.60mm maximum height. Substitutes range from 8.21mm to 9.57mm. For applications with tight vertical clearance constraints, the Dialight 5219672F (8.21mm) provides the lowest profile. The Everlight parts (8.90mm) and Broadcom HLMP-3301 series (9.19mm) require verification against PCB assembly clearance specifications. Height differences of less than 1mm typically do not impact standard PCB designs.

Q: Can multiple substitute parts be used within the same circuit?

A: Yes, provided all parts meet the circuit's electrical requirements (forward voltage, current budget) and optical requirements (brightness, viewing angle). Mixing substitutes with different brightness levels (e.g., 6mcd original with 40mcd SSL-LX5093ID) should be avoided in applications where uniform indicator brightness is required. For circuits with independent indicator branches, different substitutes can be selected based on individual branch requirements.
