VAOB-10GADE2-C Equivalent & Substitute Parts

Part Overview

The VAOB-10GADE2-C is a dual-color LED indicator manufactured by Visual Communications Company (VCC). This through-hole component combines green and red LEDs in a common cathode configuration with a 10mm diffused lens. The part is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent and substitute parts is necessary for ongoing maintenance, repair, and legacy system support where this component remains in active use.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VAOB-10GADE2-C is determined by the following critical parameters:

Primary Compatibility Criteria:

• Dual-color LED configuration (Green and Red)
• Common cathode electrical configuration
• 10mm lens diameter with diffused transparency
• Round domed lens style
• Through-hole radial mounting
• Forward voltage compatibility within acceptable operating ranges
• Test current rating of 20mA per color
• RoHS3 compliance for regulatory alignment

Secondary Consideration Criteria:

• Millicandela ratings (brightness levels)
• Dominant wavelength specifications
• Physical height dimensions
• Moisture sensitivity classification

The WP819EGW from Kingbright meets all primary compatibility criteria and qualifies as a direct substitute. While secondary parameters show variations in brightness and wavelength precision, these differences remain within acceptable tolerances for standard LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The WP819EGW qualifies as a functional substitute for the VAOB-10GADE2-C based on electrical and mechanical compatibility. Both components share identical mounting architecture, electrical configuration, and primary performance parameters.

Regulatory Compliance:

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications requiring environmental compliance documentation.

Product Status Consideration:

The VAOB-10GADE2-C carries "Not For New Designs" status, while the WP819EGW is classified as "Active." For ongoing production support and legacy system maintenance, the WP819EGW represents the current-generation equivalent from an active manufacturer.

Parameter Variance Assessment:

Forward voltage differences (0.1V to 0.2V) fall within standard LED operating tolerances and require no circuit redesign for typical indicator applications. The red wavelength variance (23nm) represents a perceptible color shift from 640nm to 617nm; applications requiring precise color matching should evaluate this difference against visual requirements. Brightness reduction (50mcd green, 60mcd red versus 80mcd and 100mcd) may impact visibility in high-ambient-light environments. Physical height increase (2.35mm) requires verification against PCB layout constraints and enclosure clearances.

Frequently Asked Questions (FAQ)

Q: Can the WP819EGW directly replace the VAOB-10GADE2-C without circuit modifications?

A: Yes, for standard indicator applications. Both components operate at compatible forward voltages and test currents. Existing series resistor values and current-limiting circuits require no adjustment. However, verify that the 2.35mm height increase does not conflict with mechanical constraints in your assembly.

Q: What is the significance of the red wavelength difference (640nm vs. 617nm)?

A: The 23nm shift moves the red color from deep red toward orange-red. In applications where color consistency is critical for user interface or safety indication, this difference may be perceptible. For general-purpose indication where red is simply "red," this variance is acceptable.

Q: Why is the WP819EGW brightness lower than the VAOB-10GADE2-C?

A: The WP819EGW produces 50mcd green and 60mcd red compared to 80mcd and 100mcd respectively. This reduction reflects different LED die specifications. For applications operating in normal indoor lighting, this brightness level remains adequate. High-ambient-light or long-distance visibility applications should evaluate whether the reduced brightness meets performance requirements.

Q: Are there any moisture sensitivity concerns when substituting?

A: The VAOB-10GADE2-C carries MSL 2 (1 Year), while the WP819EGW carries MSL 1 (Unlimited). The WP819EGW offers superior moisture resistance, eliminating any moisture-related concerns during storage and handling.

Q: What packaging considerations apply to this substitution?

A: Both components use radial through-hole packages with 10mm lens diameters and identical pin configurations. PCB footprints are interchangeable. The only mechanical consideration is the 2.35mm height difference; verify clearance above the component in your enclosure design.

Q: Is the WP819EGW suitable for new product designs?

A: Yes. The WP819EGW carries "Active" product status and is manufactured by Kingbright, an established LED component supplier. It is appropriate for both legacy system support and new designs requiring dual-color 10mm through-hole LED indicators.
