Dialight 5502405 LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The Dialight 5502405 is a 5mm red LED circuit board indicator designed for through-hole, right-angle mounting applications. This part operates at 2.2V with a 10mA rated current and delivers 7mcd luminous intensity with a 50° viewing angle. The component features a diffused lens with a round domed top in the T-1 3/4 form factor.

The 5502405 is classified as obsolete. Equivalent and substitute parts are available from the same manufacturer series to maintain design compatibility and ensure continued component availability for production and repair applications.

Substitute Part Grouping Explanation

Substitute parts for the Dialight 5502405 are classified into two categories based on electrical and mechanical parameter alignment:

Direct Substitutes (Dialight Series 550): Parts 5502405F, 5502407F, and 5502412F maintain compatibility through identical or near-identical specifications across critical parameters: red color, 650nm wavelength, 10mA current rating, 7mcd luminous intensity, 50° viewing angle, diffused lens type, 5mm T-1 3/4 form factor, and through-hole right-angle mounting. These parts are active products within the same manufacturer series and carry RoHS3 compliance certification.

Similar Alternative (Cross-Manufacturer): The Kingbright WP73EK/IDA represents a functional alternative for applications where minor parameter variations are acceptable. This part differs in lens diameter (4.80mm vs. 5mm), voltage rating (1.9V vs. 2.2V), current requirement (30mA vs. 10mA), wavelength (617nm vs. 650nm), and luminous intensity (20mcd vs. 7mcd). Selection of this alternative requires circuit design verification to accommodate the different electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Parts 5502405F, 5502407F, and 5502412F are recommended as primary substitutes for the obsolete 5502405. All three maintain active product status and carry RoHS3 compliance certification. The 5502405F and 5502407F are electrically and mechanically identical to the original part. The 5502412F operates at a marginally lower voltage (2.1V vs. 2.2V) while maintaining all other critical parameters, making it suitable for applications with flexible voltage tolerance.

For Cross-Manufacturer Substitution: The Kingbright WP73EK/IDA is classified as a similar alternative rather than a direct substitute due to significant parameter deviations in voltage (1.9V), current (30mA), wavelength (617nm), and luminous intensity (20mcd). This part is appropriate only when circuit design accommodates these electrical differences and when the increased brightness (20mcd vs. 7mcd) and wider viewing angle (60° vs. 50°) align with application requirements.

Frequently Asked Questions (FAQ)

Q: Can I use 5502405F as a direct replacement for 5502405? A: Yes. The 5502405F maintains identical electrical specifications (2.2V, 10mA, 7mcd) and mounting configuration (through-hole, right-angle). The primary difference is packaging format (bulk vs. standard). This part is active and RoHS3 compliant.

Q: What is the difference between 5502407F and 5502412F? A: Both parts are mechanically and optically identical to the original 5502405. The 5502412F operates at 2.1V compared to 2.2V for the 5502407F. Select 5502412F only if your circuit design accommodates the lower voltage specification.

Q: Can I substitute the Kingbright WP73EK/IDA for the Dialight 5502405? A: The Kingbright part is functionally similar but not electrically equivalent. It requires 30mA (vs. 10mA), operates at 1.9V (vs. 2.2V), and produces 20mcd (vs. 7mcd). Use this part only if your circuit design is modified to accommodate these parameter differences.

Q: Are all substitute parts RoHS compliant? A: The direct Dialight substitutes (5502405F, 5502407F, 5502412F) are RoHS3 compliant. The Kingbright WP73EK/IDA is also RoHS3 compliant. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Does lens size affect mechanical fit? A: Yes. The 5502405, 5502407F, and 5502412F use the 5mm T-1 3/4 form factor. The Kingbright WP73EK/IDA uses a 4.80mm diameter lens, which may require mechanical design verification for PCB mounting hole compatibility.

Q: What viewing angle differences should I consider? A: The Dialight parts maintain a 50° viewing angle. The Kingbright WP73EK/IDA provides a 60° viewing angle. Select based on application requirements for light distribution and visibility range.
