DC5305S LED Blue-Green 5mm Through Hole Equivalent & Substitute Parts

Part Overview

The DC5305S is a blue-green 505nm LED indication component manufactured by Stanley Electric Co, designed for discrete 3.5V radial through-hole applications. This part is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure supply chain availability. The DC5305S features a 5mm round domed lens with 800mcd brightness rating and 30° viewing angle, suitable for standard indicator applications requiring blue-green spectral output.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete DC5305S is based on strict alignment of the following critical parameters:

Mandatory Matching Criteria:

• Wavelength - Dominant: 505nm (blue-green spectral output)
• Lens Size: 5mm, T-1 3/4 (physical form factor)
• Lens Style: Round with Domed Top (optical geometry)
• Lens Color: Colorless (no color filtering)
• Lens Transparency: Clear (optical transmission)
• Mounting Type: Through Hole (circuit board integration)
• Package / Case: Radial (lead configuration)
• Color: Blue-Green (visual indication color)
• Configuration: Standard (no special variants)

Allowable Parameter Variations:

• Voltage - Forward (Vf): 3.2V to 3.5V (within typical blue-green LED range)
• Current - Test: 20mA (standard test condition)
• Millicandela Rating: Higher values acceptable (brightness enhancement)
• Viewing Angle: Narrower angles acceptable (15° to 30°)
• Height (Max): Variation within mechanical envelope constraints

The OVLGC0C6B9 from TT Electronics/Optek Technology meets all mandatory criteria and represents an active, in-stock equivalent suitable for direct substitution in DC5305S applications.

Parameter Comparison

Engineering Selection Recommendations

The OVLGC0C6B9 is the designated equivalent for DC5305S replacement based on the following engineering factors:

Product Status Alignment: The DC5305S is classified as obsolete with no active manufacturing. The OVLGC0C6B9 maintains active product status with 25,315 units in current inventory, ensuring long-term supply chain continuity.

Compliance and Certification: Both components share identical REACH Status (REACH Unaffected) and ECCN classification (EAR99). The OVLGC0C6B9 carries RoHS3 Compliance certification, meeting modern regulatory requirements for electronic components.

Electrical Compatibility: Forward voltage differential of 0.3V (3.5V to 3.2V) falls within acceptable operating range for standard LED indicator circuits. Test current remains constant at 20mA across both components.

Optical and Mechanical Compatibility: Dominant wavelength (505nm) and lens specifications (5mm round domed, colorless, clear) are identical. Height variation of 1.11mm (7.80mm to 8.91mm) remains within typical PCB clearance tolerances for through-hole applications.

Performance Enhancement: The OVLGC0C6B9 provides 28.75x brightness increase (800mcd to 23,000mcd) while maintaining narrower 15° viewing angle compared to 30° on the original part. This represents improved luminous intensity suitable for applications requiring enhanced visibility.

Frequently Asked Questions (FAQ)

Q: Can the OVLGC0C6B9 directly replace the DC5305S without circuit modification?

A: Direct substitution is supported for applications where the 0.3V forward voltage reduction (3.5V to 3.2V) and narrower 15° viewing angle are acceptable. Circuit current-limiting resistor values may require adjustment to account for the lower forward voltage and significantly higher brightness output.

Q: What is the impact of the 1.11mm height difference between DC5305S and OVLGC0C6B9?

A: The OVLGC0C6B9 maximum height of 8.91mm compared to DC5305S at 7.80mm represents a 1.11mm increase. This variation must be evaluated against PCB clearance requirements, enclosure constraints, and mechanical assembly specifications for the target application.

Q: How does the 23,000mcd brightness of OVLGC0C6B9 compare to the 800mcd DC5305S?

A: The OVLGC0C6B9 provides substantially higher luminous intensity (28.75x increase). Applications requiring the original 800mcd specification must implement current-limiting or PWM dimming to achieve equivalent brightness levels and prevent over-illumination.

Q: Are there wavelength differences between these components?

A: Both components specify 505nm dominant wavelength, ensuring identical blue-green spectral output. The DC5305S provides 502nm peak wavelength data; the OVLGC0C6B9 peak wavelength is not specified in available documentation.

Q: What is the significance of the 15° versus 30° viewing angle difference?

A: The DC5305S provides 30° viewing angle for broader light distribution. The OVLGC0C6B9 narrows this to 15°, concentrating light output in a more focused beam. Applications requiring wide-angle indication must account for this reduced angular distribution.

Q: Are packaging and mounting configurations identical?

A: Both components use 5mm T-1 3/4 round domed lens packages with radial through-hole mounting. Packaging format (bulk for OVLGC0C6B9 versus standard for DC5305S) affects procurement and handling but does not impact electrical or mechanical compatibility.

Q: What compliance certifications apply to the OVLGC0C6B9?

A: The OVLGC0C6B9 carries RoHS3 Compliance certification and maintains REACH Unaffected status. Both components share EAR99 ECCN classification and identical HTSUS code (8541.41.0000).
