Dialight 5530744 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5530744 is a dual-level LED circuit board indicator featuring integrated green and yellow LEDs in a 3mm T-1 through-hole right-angle configuration. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

The 5530744 provides a 2-high LED configuration with clear lens optics, delivering 6.3mcd green and 4.3mcd yellow output at 20mA operating current and 2.1V forward voltage. Its right-angle mounting design enables direct PCB integration for status indication applications.

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5530744 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Identical voltage rating (2.1V), current rating (20mA), wavelength specifications (565nm green, 585nm yellow), and luminous intensity (6.3mcd green, 4.3mcd yellow)
• Mechanical Compatibility: Matching lens size (3mm T-1), lens style (round with domed top), mounting type (through hole, right angle), and viewing angle (80°)
• Configuration: Dual-level (2 high) LED arrangement with green and yellow color combination
• Regulatory Compliance: REACH Unaffected status and EAR99 ECCN classification maintained

The substitute part 5530744F maintains full electrical and mechanical equivalence to the main part. The primary distinction is the lens type: the substitute features a diffused lens versus the clear lens of the original component. This optical difference does not affect electrical performance or mechanical fit, making it a valid substitute for applications where diffused light output is acceptable.

Engineering Selection Recommendations

The Dialight 5530744F is the direct substitute for the obsolete 5530744. Selection of the 5530744F is supported by the following factors:

• Product Status: The 5530744F maintains active product status, ensuring continued availability and manufacturing support from Dialight, whereas the original 5530744 is obsolete.
• Regulatory Compliance: Both parts maintain identical REACH Unaffected status and EAR99 ECCN classification, ensuring no change to export control or environmental compliance requirements.
• Electrical Equivalence: All electrical parameters—voltage, current, wavelength, and luminous intensity—are identical between the main part and substitute.
• Mechanical Equivalence: Mounting configuration, lens dimensions, and form factor are fully compatible, enabling direct PCB integration without redesign.
• Optical Consideration: The diffused lens of the 5530744F provides light scattering compared to the clear lens of the 5530744. This difference is optical only and does not affect electrical performance or mechanical fit. Selection between clear and diffused optics depends on application-specific visibility and light distribution requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5530744F be used as a direct replacement for the 5530744 in existing designs?

A: Yes. The 5530744F is electrically and mechanically equivalent to the 5530744. Both parts operate at identical voltage (2.1V), current (20mA), and produce identical luminous intensity (6.3mcd green, 4.3mcd yellow). The mounting configuration and physical dimensions are identical, enabling direct PCB substitution without circuit modification.

Q: What is the difference between the clear lens of the 5530744 and the diffused lens of the 5530744F?

A: The lens type differs in optical characteristics only. The 5530744 features a clear lens that produces focused light output, while the 5530744F features a diffused lens that scatters light over a wider area. Both lenses maintain the same 80° viewing angle and 3mm T-1 form factor. The choice between clear and diffused optics depends on whether the application requires concentrated or dispersed light distribution.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both the 5530744 and 5530744F maintain identical REACH Unaffected status, EAR99 ECCN classification, and MSL 1 (Unlimited) moisture sensitivity rating. There are no differences in regulatory compliance or export control requirements.

Q: Why is the 5530744 listed as obsolete?

A: The 5530744 has been discontinued by Dialight. The 5530744F is the active equivalent part and is the recommended source for new procurement and ongoing system support.

Q: Will substituting the 5530744F require any circuit design changes?

A: No circuit design changes are required. The 5530744F is a direct mechanical and electrical substitute. The only consideration is the optical difference between clear and diffused lenses, which is a visual characteristic and does not affect circuit operation or component performance.

Q: Is the 5530744F available in the same packaging as the 5530744?

A: The 5530744F is supplied in bulk packaging, whereas the original 5530744 packaging specification is not detailed in the provided data. Both parts use identical through-hole right-angle mounting, ensuring compatibility with standard PCB assembly processes.
