Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5510312802F are identified based on the following critical parameters that determine functional and mechanical compatibility:

Color matching: Yellow wavelength specification (585nm nominal range) Configuration: Single LED element Lens characteristics: Diffused, tinted lens type with round domed top geometry Lens diameter: 3mm class (3.00mm or 3mm) Compliance: ROHS3 compliant, REACH unaffected status Electrical operating range: Forward voltage 1.95V to 2.1V, current 30mA to 60mA

The Kingbright WP934AD/YD qualifies as a substitute based on matching color, configuration, lens type, lens style, lens size class, and regulatory compliance. Electrical parameters fall within acceptable operating ranges for circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Dialight 5510312802F and Kingbright WP934AD/YD maintain active product status and full regulatory compliance under ROHS3 and REACH standards. Selection between these parts should be based on specific circuit requirements:

The 5510312802F operates at 2.1V with 60mA current draw and provides 6.3mcd brightness output across a 45° viewing angle.

The WP934AD/YD operates at lower voltage (1.95V) and current (30mA) with higher brightness output (15mcd) across a 40° viewing angle. The WP934AD/YD features right-angle through-hole mounting, whereas the 5510312802F is configured for standard circuit board indicator mounting.

Both parts share identical lens characteristics, diffused tinted construction, and 3mm class diameter specifications. Wavelength peaks are within 3nm of each other (585nm vs 588nm), maintaining consistent yellow color perception.

Frequently Asked Questions (FAQ)

Q: Can the WP934AD/YD directly replace the 5510312802F in existing designs?

A: Direct replacement requires circuit evaluation. The WP934AD/YD operates at lower voltage (1.95V vs 2.1V) and current (30mA vs 60mA), necessitating resistor recalculation in current-limiting circuits. The right-angle through-hole mounting of the WP934AD/YD differs from standard board indicator mounting of the 5510312802F.

Q: Are the color specifications identical between these parts?

A: Both parts are yellow with peak wavelengths within 3nm (585nm vs 588nm). Both use diffused, tinted lens construction. Color perception will be visually equivalent in circuit board indicator applications.

Q: What are the compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity levels are identical at MSL 1 (unlimited). No compliance barriers exist for substitution.

Q: How do brightness levels compare?

A: The WP934AD/YD provides 15mcd versus 6.3mcd for the 5510312802F. Higher brightness may be advantageous in high-ambient-light environments but requires verification that circuit design accommodates the lower current requirement.

Q: What mounting considerations apply to substitution?

A: The 5510312802F is a standard circuit board indicator LED. The WP934AD/YD is specified as right-angle through-hole, T-1 package. Physical board layout and mounting hole positioning must be verified before substitution.
