Dialight 5660306 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5660306 is a yellow LED circuit board indicator designed for through-hole, right-angle mounting applications. This part operates at 2.1V with a 20mA forward current and delivers 4.6mcd luminous intensity with a 110° viewing angle. The component features a diffused, tinted rectangular lens with a flat top profile.

The 5660306 carries an obsolete product status, making identification of active equivalent parts essential for ongoing production and maintenance applications. Direct substitutes and functionally similar alternatives are available from both Dialight and alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5660306 is determined by the following critical parameters:

• Color: Yellow (583nm peak wavelength)
• Configuration: Single LED
• Lens Type: Diffused, Tinted
• Lens Style: Rectangle with Flat Top
• Mounting Type: Through Hole
• Viewing Angle: 110°

Substitute parts are classified into two categories:

Direct Manufacturer Substitutes: Parts 5660306F and 5660307F maintain identical electrical and optical specifications (2.1V, 20mA, 4.6mcd, 583nm, 110° viewing angle) with matching mechanical form factors. These parts differ only in packaging configuration and RoHS compliance status.

Similar Manufacturer Substitute: Part WP113WH/YD from Kingbright provides functional equivalence with minor parameter variations. This part maintains the same color, lens type, lens style, mounting configuration, and viewing angle. Electrical parameters differ: 1.95V forward voltage and 30mA forward current with 4mcd luminous intensity at 588nm peak wavelength.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): Parts 5660306F and 5660307F are the primary substitutes for the obsolete 5660306. Both maintain identical electrical specifications (2.1V, 20mA) and optical characteristics (4.6mcd, 583nm, 110° viewing angle). Both parts carry active product status and ROHS3 compliance, addressing regulatory requirements that the original part does not meet. Selection between 5660306F and 5660307F depends on packaging requirements; 5660306F is available in bulk packaging, while 5660307F is also available in bulk.

For Functional Equivalence: The Kingbright WP113WH/YD provides functional substitution when circuit design accommodates parameter variations. This part operates at a lower forward voltage (1.95V versus 2.1V) and requires higher forward current (30mA versus 20mA). The luminous intensity is marginally higher at 4mcd. The part maintains identical lens characteristics, viewing angle, and mounting configuration. This substitute is suitable only when the application circuit can tolerate the electrical parameter differences.

Compliance Consideration: The original 5660306 is RoHS non-compliant. Both Dialight direct substitutes (5660306F and 5660307F) and the Kingbright alternative (WP113WH/YD) are ROHS3 compliant, meeting current regulatory standards for new designs and production.

Frequently Asked Questions (FAQ)

Q: Can 5660306F directly replace 5660306 without circuit modification?

A: Yes. The 5660306F maintains identical electrical parameters (2.1V forward voltage, 20mA forward current) and optical specifications (4.6mcd, 583nm, 110° viewing angle). No circuit redesign is required for direct substitution.

Q: What is the difference between 5660306F and 5660307F?

A: Both parts are electrically and optically identical, maintaining the same 2.1V, 20mA, 4.6mcd specifications and 583nm wavelength. The parts differ in base product number designation and packaging configuration. Both are active products with ROHS3 compliance.

Q: Can the Kingbright WP113WH/YD replace the Dialight 5660306?

A: The Kingbright WP113WH/YD provides functional equivalence with parameter variations. Forward voltage is lower (1.95V versus 2.1V) and forward current is higher (30mA versus 20mA). Luminous intensity is slightly higher at 4mcd. Substitution requires circuit verification to confirm tolerance of these electrical differences. Optical characteristics (lens type, style, viewing angle) remain compatible.

Q: Why is the original 5660306 marked as obsolete?

A: The 5660306 carries obsolete product status. Active equivalents 5660306F and 5660307F are available from the same manufacturer with improved RoHS compliance.

Q: Are there packaging differences between the substitute parts?

A: The 5660306 original part does not specify packaging. Both 5660306F and 5660307F are available in bulk packaging. The Kingbright WP113WH/YD does not specify packaging configuration in the provided data.

Q: Do all substitute parts meet current RoHS requirements?

A: Yes. Both Dialight substitutes (5660306F and 5660307F) and the Kingbright alternative (WP113WH/YD) are ROHS3 compliant. The original 5660306 is RoHS non-compliant.

Q: What is the viewing angle specification for all parts?

A: All parts maintain a 110° viewing angle, ensuring consistent light distribution characteristics across the main part and all substitutes.
