Dialight 5530211 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5530211 is a dual-level red LED circuit board indicator designed for through-hole, right-angle mounting applications. This component features a 3mm T-1 form factor with diffused, tinted lens and operates at 1.7V with 2mA current consumption. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain compatibility across mounting configuration, lens characteristics, and electrical operating parameters while accommodating variations in current rating and brightness output.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5530211 is determined by the following critical parameters:

• Mounting Configuration: Through-hole, right-angle orientation required
• Lens Characteristics: Diffused, tinted lens with round domed top
• Form Factor: 3mm T-1 or equivalent diameter (2.9mm acceptable within mechanical tolerance)
• Color: Red (x 2) dual-level configuration
• Wavelength Range: 635nm peak wavelength (617nm acceptable for red spectrum compatibility)
• Electrical Compatibility: Voltage rating 1.7V–2V; current rating 2mA–30mA (higher current ratings acceptable with appropriate circuit design)
• Regulatory Compliance: ROHS3 compliant, REACH unaffected, MSL 1

Substitutes are grouped into two categories:

Direct Manufacturer Substitute: 5530211F (Dialight) – identical electrical and mechanical specifications with active product status.

Cross-Manufacturer Substitutes: SSF-LXH240LIID (Lumex Opto/Components Inc.) and WP934MD/2LID (Kingbright) – functionally equivalent with allowable parameter variations in current, brightness, and viewing angle.

Parameter Comparison

Engineering Selection Recommendations

5530211F (Dialight) is the primary substitute for the obsolete 5530211. This part maintains identical electrical specifications (1.7V, 2mA), mechanical form factor (3mm T-1), and optical characteristics (635nm, 1.6mcd). The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory alignment.

SSF-LXH240LIID (Lumex Opto/Components Inc.) serves as a cross-manufacturer alternative where higher brightness output is acceptable. This part operates at 2V with 20mA current and delivers 15mcd brightness compared to the original 1.6mcd. The 80° viewing angle provides wider light distribution. Circuit design must accommodate the increased voltage and current requirements. ROHS3 compliance and active production status support supply chain continuity.

WP934MD/2LID (Kingbright) is suitable for applications where lower brightness (0.6mcd) and reduced viewing angle (40°) are compatible with system requirements. The 2.9mm lens diameter is mechanically compatible with 3mm mounting holes. Voltage rating matches the original at 1.7V, but current consumption increases to 30mA. ROHS3 compliance and active production ensure regulatory and availability alignment.

Selection between these substitutes depends on circuit power budget, brightness requirements, and viewing angle specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can 5530211F be used as a direct replacement for 5530211?

A: Yes. The 5530211F maintains identical electrical (1.7V, 2mA), optical (635nm, 1.6mcd), and mechanical (3mm T-1, through-hole right-angle) specifications. The primary difference is product status: 5530211F is active in production while 5530211 is obsolete. No circuit modifications are required.

Q: What are the key differences between SSF-LXH240LIID and the original 5530211?

A: The SSF-LXH240LIID operates at 2V (versus 1.7V) with 20mA current (versus 2mA) and delivers 15mcd brightness (versus 1.6mcd). The viewing angle is specified at 80° compared to the unspecified angle of the original. All other parameters—lens type, style, size, mounting configuration, and color—remain compatible. Circuit design must accommodate the higher voltage and current.

Q: Is the WP934MD/2LID mechanically compatible with 5530211 mounting holes?

A: The WP934MD/2LID has a 2.9mm lens diameter compared to the 3mm of the original. This 0.1mm difference is within standard mechanical tolerance for through-hole PCB mounting and does not prevent physical installation. Verify mounting hole specifications in your PCB design.

Q: Do all substitute parts meet the same regulatory requirements as 5530211?

A: The 5530211F, SSF-LXH240LIID, and WP934MD/2LID are all ROHS3 compliant and REACH unaffected with MSL 1 (unlimited moisture sensitivity). These certifications align with the original part's regulatory profile.

Q: Which substitute should I select if brightness is critical to my application?

A: If higher brightness is required, SSF-LXH240LIID (15mcd) is appropriate. If lower brightness is acceptable or preferred, WP934MD/2LID (0.6mcd) is suitable. For brightness matching the original specification (1.6mcd), 5530211F is the only option.

Q: Can I use SSF-LXH240LIID in a circuit designed for 1.7V operation?

A: No. SSF-LXH240LIID requires 2V minimum operating voltage. Using it in a 1.7V circuit will result in insufficient brightness or non-operation. Circuit redesign is necessary to accommodate the higher voltage requirement.
