DB5304X LED Blue Clear 5MM Round T/H Equivalent & Substitute Parts

Part Overview

The DB5304X is a blue 470nm LED indication component manufactured by Stanley Electric Co, designed for through-hole mounting in discrete 3.5V radial configurations. This part is classified as obsolete, necessitating identification of active equivalent components for ongoing design requirements and production continuity. Substitute parts must maintain functional compatibility across optical, electrical, and mechanical parameters while meeting current product availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DB5304X is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Color: Blue
• Wavelength - Dominant: 470nm
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole
• Package / Case: Radial
• Current - Test: 20mA

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Typ): ±0.3V tolerance
• Millicandela Rating: Component-specific brightness variation
• Viewing Angle: Component-specific directional characteristics
• Lens Style: Round configuration variants (domed or flat top)
• Height (Max): ±0.5mm tolerance
• Wavelength - Peak: ±2nm tolerance

All three identified substitute parts meet the mandatory matching criteria and fall within allowable variation ranges for electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

383-2SUBC/C470/S400-A6 (Everlight Electronics Co Ltd)

This substitute is active and ROHS3 compliant. Forward voltage is 3.4V, representing a 0.1V reduction from the DB5304X specification. Millicandela rating of 3200mcd significantly exceeds the original 300mcd, suitable for applications requiring higher luminous intensity. Viewing angle of 20° is narrower than the original 25°, affecting directional light distribution. Height tolerance of 8.90mm is within acceptable mechanical variation. This part is recommended for designs where increased brightness is acceptable and viewing angle constraints do not apply.

HLMP-DS25-F0000 (Broadcom Limited)

This substitute is active and ROHS3 compliant. Forward voltage is 3.2V, representing a 0.3V reduction from the DB5304X specification. Millicandela rating of 110mcd is significantly lower than the original 300mcd, suitable for applications requiring reduced brightness or lower power consumption. Viewing angle of 25° matches the original specification exactly. Height of 9.19mm exceeds the original 8.80mm by 0.39mm, within acceptable mechanical tolerance. This part is recommended for designs where lower brightness and exact viewing angle matching are required.

OVLLB8C7 (TT Electronics/Optek Technology)

This substitute is active and ROHS3 compliant. Forward voltage is 3.2V, representing a 0.3V reduction from the DB5304X specification. Millicandela rating of 440mcd exceeds the original 300mcd, providing increased brightness. Viewing angle of 85° is significantly wider than the original 25°, providing broader light distribution. Lens style is round with flat top rather than domed top, affecting optical characteristics. Height of 6.80mm is 2.0mm lower than the original 8.80mm, representing the most compact option. This part is recommended for designs where wide viewing angle and compact height are prioritized.

Frequently Asked Questions (FAQ)

Q: Can the DB5304X be directly replaced with any of these substitute parts?

A: All three substitute parts meet the mandatory matching criteria for color, wavelength, lens size, mounting type, and package configuration. However, electrical and optical characteristics vary. Direct replacement requires verification that forward voltage tolerance, brightness level, and viewing angle are acceptable for the specific application circuit.

Q: What is the significance of the forward voltage differences?

A: The DB5304X specifies 3.5V typical forward voltage. Substitutes range from 3.2V to 3.4V. In series-resistor-limited circuits, lower forward voltage results in higher LED current and brightness. Circuit redesign may be necessary if the original design assumes 3.5V forward voltage. Verify current-limiting resistor calculations for the selected substitute.

Q: How do millicandela ratings affect substitution?

A: Millicandela rating indicates luminous intensity. The DB5304X is rated at 300mcd. The Everlight part (3200mcd) is significantly brighter, the Broadcom part (110mcd) is dimmer, and the Optek part (440mcd) is moderately brighter. Selection depends on application brightness requirements. Higher brightness may cause visual glare; lower brightness may reduce visibility.

Q: What is the impact of viewing angle differences?

A: The DB5304X specifies 25° viewing angle. The Everlight part is 20° (narrower), and the Optek part is 85° (much wider). Narrower angles concentrate light in a specific direction; wider angles distribute light broadly. Application placement and visibility requirements determine the appropriate viewing angle.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All three substitute parts are ROHS3 compliant. The DB5304X compliance status is not provided in the available data. If RoHS3 compliance is a design requirement, all three substitutes meet this criterion.

Q: What are the height differences and do they matter?

A: The DB5304X maximum height is 8.80mm. Substitutes range from 6.80mm (Optek) to 9.19mm (Broadcom). Height differences of up to 0.39mm are within typical PCB layout tolerances. The Optek part is 2.0mm shorter, which may affect visual alignment in indicator panel applications. Verify mechanical clearance in the target application.

Q: Which substitute offers the closest electrical match?

A: The Everlight 383-2SUBC/C470/S400-A6 offers the closest forward voltage match at 3.4V, only 0.1V below the DB5304X specification. This minimizes circuit redesign requirements if the original design is voltage-sensitive.

Q: Which substitute offers the closest optical match?

A: The Broadcom HLMP-DS25-F0000 offers the closest viewing angle match at exactly 25°, identical to the DB5304X. However, its millicandela rating of 110mcd is significantly lower. The Optek OVLLB8C7 offers higher brightness at 440mcd but with a much wider 85° viewing angle.

Q: Can lens style differences affect performance?

A: Yes. The DB5304X has a domed top lens; the Optek substitute has a flat top lens. Domed lenses provide slightly different optical focusing characteristics compared to flat lenses. This affects light distribution patterns and may impact visual appearance in indicator applications. Verify optical performance in the target application environment.

Q: What inventory considerations apply?

A: The DB5304X has 813 pieces in stock (obsolete status). The Optek OVLLB8C7 has the highest inventory at 30,187 pieces, followed by Everlight at 1,089 pieces, and Broadcom at 681 pieces. For long-term production, the Optek part offers the most reliable supply continuity.
