LED Circuit Board Indicator 5530188 Equivalent & Substitute Parts

Part Overview

The Dialight 5530188 is a LED Circuit Board Indicator (CBI) featuring a 3mm bi-level blue diffused lens configuration with right-angle through-hole mounting. This component is designed for applications requiring dual-level blue indicator functionality at 4.6V with 10mA current consumption. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 5530188 is based on strict alignment of the following critical parameters:

• Color specification: Blue (x 2) configuration
• Wavelength - Peak: 428nm
• Electrical ratings: 4.6V voltage, 10mA current
• Optical performance: 12.5mcd brightness, 70° viewing angle
• Lens type: Diffused
• Mounting configuration: Through Hole, Right Angle
• Series compatibility: Dialight 553 series

The substitute part 5530188F maintains all critical electrical and optical parameters while differing only in lens physical form factor (Round with Domed Top, 3mm T-1 package) and product status (Active). This lens geometry variation does not affect electrical compatibility or core functional performance in circuit board indicator applications.

Engineering Selection Recommendations

The 5530188F is the direct substitute for the obsolete 5530188. Both components are manufactured by Dialight within the 553 series and maintain identical electrical specifications, optical performance characteristics, and regulatory compliance status. The 5530188F carries Active product status, ensuring continued availability and supply chain support. Both parts are REACH Unaffected and classified under ECCN EAR99, maintaining equivalent export and regulatory standing. The substitute part is available in bulk packaging with 1549 units in current inventory, compared to 946 units of the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the 5530188F be used as a direct replacement for the 5530188?

A: Yes. Both parts share identical electrical ratings (4.6V, 10mA), optical specifications (428nm wavelength, 12.5mcd, 70° viewing angle), mounting configuration (Through Hole, Right Angle), and lens type (Diffused). The primary difference is lens physical form factor and product status.

Q: What is the difference between the lens styles of these two parts?

A: The 5530188 features an unspecified lens style, while the 5530188F specifies a Round with Domed Top lens in 3mm T-1 package. Both maintain diffused lens type and identical optical performance parameters.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are REACH Unaffected, classified as EAR99, and share the same HTSUS code (8541.41.0000). Moisture Sensitivity Level is identical at MSL 1 (Unlimited) for both components.

Q: Why is the 5530188 classified as obsolete?

A: The 5530188 is listed as obsolete by the manufacturer. The 5530188F, with Active product status, represents the current production equivalent within the Dialight 553 series.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching: color (Blue x 2), wavelength (428nm), voltage (4.6V), current (10mA), brightness (12.5mcd), viewing angle (70°), lens type (Diffused), and mounting configuration (Through Hole, Right Angle).
