Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 104990107 is determined by the following critical parameters:

Configuration Match: The substitute must maintain a 10-segment bar display in DIP (Dual In-line Package) format to ensure mechanical and electrical compatibility with existing PCB layouts and connector interfaces.

Color Specification: Blue wavelength emission is required. The main part specifies 463nm peak wavelength; substitute parts operating within the blue spectrum (460nm range) are functionally equivalent for visual indication purposes.

Electrical Compatibility: The substitute must operate within compatible voltage and current ranges. The main part operates at 3.2V/100mA. Substitutes with lower voltage ratings (3V) and reduced current requirements (30mA) remain compatible when circuit designs accommodate current-limiting resistor adjustments.

Optical Performance: Lens style (Rectangle with Flat Top) must be maintained for consistent light distribution and mechanical fit in indicator panel assemblies.

Compliance Requirements: RoHS compliance status ensures environmental and regulatory alignment with modern manufacturing standards.

The identified substitute XGCBDX10D meets these criteria while offering active product status and improved availability.

Engineering Selection Recommendations

Primary Substitute: XGCBDX10D

The SunLED XGCBDX10D is the qualified substitute for the obsolete 104990107. Selection rationale is based on the following engineering factors:

Product Status: The XGCBDX10D maintains Active product status, ensuring long-term availability and manufacturing continuity. This directly addresses the obsolescence limitation of the main part.

Compliance Alignment: Both parts maintain MSL Level 1 (Unlimited) moisture sensitivity ratings and RoHS compliance certifications, ensuring compatibility with current manufacturing and environmental standards. The substitute achieves ROHS3 compliance, representing current regulatory requirements.

Configuration Compatibility: Identical 10-segment bar DIP configuration and blue color specification ensure direct functional equivalence in visual indication applications.

Electrical Adjustment Consideration: The substitute operates at reduced voltage (3V vs. 3.2V) and current (30mA vs. 100mA). Circuit designs must accommodate these reduced electrical requirements through appropriate current-limiting resistor selection. The lower current rating reduces power dissipation and thermal load.

Optical Performance Trade-off: The substitute delivers reduced luminous intensity (9.4mcd vs. 80mcd). Applications requiring the original brightness level must evaluate whether the reduced intensity meets visibility requirements in the target operating environment.

Mechanical Fit: Both parts feature Rectangle with Flat Top lens styling, maintaining consistent light distribution characteristics and panel assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can XGCBDX10D be used as a direct drop-in replacement for 104990107?

A: The XGCBDX10D maintains identical configuration (10-segment bar DIP) and lens styling, enabling mechanical compatibility. However, electrical circuit adjustments are required due to reduced voltage (3V vs. 3.2V) and current (30mA vs. 100mA) specifications. Current-limiting resistor values must be recalculated for the substitute part.

Q: What is the impact of the reduced millicandela rating (9.4mcd vs. 80mcd)?

A: The substitute delivers approximately 11.75% of the original luminous intensity. Applications requiring high-brightness indication in ambient light conditions must evaluate whether this reduced intensity provides adequate visibility. Low-light or controlled-environment applications typically accommodate this reduction without performance impact.

Q: Are there mechanical differences between the two parts?

A: Both parts feature identical DIP configuration and Rectangle with Flat Top lens styling. The substitute specifies lens dimensions (5.08mm x 1.78mm), while the main part does not provide this specification. Both are Through Hole mounted components compatible with standard PCB layouts.

Q: What compliance certifications apply to the substitute?

A: The XGCBDX10D maintains RoHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, meeting current environmental and manufacturing standards. REACH Unaffected status indicates no restricted substance concerns.

Q: How should circuit design be modified when substituting XGCBDX10D for 104990107?

A: Recalculate current-limiting resistor values based on the reduced operating voltage (3V) and current (30mA) specifications of the substitute. Verify that the reduced luminous intensity (9.4mcd) meets application visibility requirements. No other circuit modifications are necessary for the 10-segment bar configuration.

Q: What is the wavelength difference between the two parts?

A: The main part specifies 463nm peak wavelength, while the substitute operates at 460nm. Both wavelengths fall within the blue spectrum and are visually indistinguishable in typical indicator applications. The 3nm difference does not affect functional performance or color perception.
