405-BR24H-O LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The 405-BR24H-O is a red LED panel indicator manufactured by Visual Communications Company (VCC), designed for 24V applications with a 0.25" (6.35mm) round panel cutout. This component is classified as Obsolete product status, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations.

The 405-BR24H-O features a clear lens with 60° viewing angle, 17mA maximum current rating, and 14mcd brightness output at 635nm peak wavelength. PC pin termination provides direct panel mounting capability. As an obsolete component, sourcing alternatives from active product lines ensures long-term availability and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 405-BR24H-O is determined by the following critical parameters:

Mandatory Matching Criteria:

• Voltage Rating: 24V DC operation
• Lamp Color: Red
• Termination Style: PC Pin (panel mount)
• Panel Cutout Shape: Round
• RoHS Compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Panel Cutout Dimensions: Mechanical compatibility within panel mounting tolerance
• Current Rating: May exceed 17mA maximum (substitute can operate at higher current capacity)
• Millicandela Rating: Brightness variation acceptable if application does not require specific luminous intensity
• Wavelength - Peak: Red spectrum variation (635nm to 700nm range) acceptable for general indication purposes
• Viewing Angle: May differ from 60° if application permits alternative viewing geometry
• Lens Transparency: Clear or diffused acceptable for indicator function

The substitute part L65DR24L meets all mandatory matching criteria while operating within allowable variation parameters for the 24V red LED panel indicator category.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The L65DR24L is a valid substitute for the obsolete 405-BR24H-O based on electrical and mechanical compatibility within the 24V red LED panel indicator category. Both components are ROHS3 compliant and carry identical export classification (EAR99).

Critical Implementation Considerations:

1. Panel Cutout Modification Required: The L65DR24L requires a 0.315" (8.00mm) round panel cutout compared to the 405-BR24H-O specification of 0.25" (6.35mm). Existing panel mounting holes must be enlarged or new panels fabricated to accommodate the larger diameter.

2. Optical Performance Variation: The L65DR24L operates at 10mcd brightness versus the 405-BR24H-O at 14mcd. The substitute also features a 30° viewing angle compared to the original 60° specification. Applications requiring specific brightness or wide-angle visibility must evaluate whether this reduction is acceptable.

3. Current Rating: The L65DR24L maximum current rating of 20mA exceeds the 405-BR24H-O specification of 17mA. Existing circuit designs operating at 17mA or below remain compatible without modification.

4. Wavelength Shift: Peak wavelength shifts from 635nm to 700nm. Both wavelengths fall within the red spectrum; however, applications with color-critical requirements should verify visual compatibility.

5. Product Status: The L65DR24L is classified as Active product status, ensuring continued availability and supply chain support compared to the Obsolete 405-BR24H-O.

Frequently Asked Questions (FAQ)

Q: Can the L65DR24L directly replace the 405-BR24H-O without any modifications?

A: Electrical substitution is direct; however, mechanical panel modification is required. The L65DR24L panel cutout diameter of 0.315" (8.00mm) is larger than the 405-BR24H-O specification of 0.25" (6.35mm). Existing panel mounting holes must be enlarged to accommodate the substitute component.

Q: What is the impact of the 4mcd brightness difference between these components?

A: The L65DR24L operates at 10mcd compared to the 405-BR24H-O at 14mcd. This represents approximately 29% lower brightness output. Applications requiring specific luminous intensity for visibility or detection purposes must evaluate whether this reduction meets functional requirements.

Q: Are there differences in viewing angle between these components?

A: Yes. The 405-BR24H-O provides 60° viewing angle while the L65DR24L provides 30° viewing angle. The substitute has a narrower viewing cone. Applications requiring wide-angle visibility must assess whether the 30° specification is acceptable for the intended installation geometry.

Q: Do both components meet the same regulatory compliance standards?

A: Yes. Both the 405-BR24H-O and L65DR24L are ROHS3 compliant and classified under ECCN EAR99. Regulatory compliance is equivalent between the two components.

Q: What is the significance of the wavelength difference (635nm versus 700nm)?

A: Both wavelengths fall within the red spectrum. The 405-BR24H-O operates at 635nm (standard red) while the L65DR24L operates at 700nm (deep red). Visual color perception difference is minimal for general indicator applications; however, color-critical applications should perform visual comparison testing.

Q: Is the higher current rating of the L65DR24L (20mA versus 17mA) a concern?

A: No. The higher current rating indicates the substitute can safely operate at currents up to 20mA. Existing circuits designed for 17mA operation remain fully compatible. The substitute provides additional current capacity margin without requiring circuit modification.

Q: What packaging format is the L65DR24L supplied in?

A: The L65DR24L is supplied in Bulk packaging. The 405-BR24H-O packaging format is not specified in the provided data.
