Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 104990108 is determined by the following critical parameters:

Configuration Match: The substitute part must maintain a Bar - 10 Wide, DIP configuration to ensure mechanical and electrical compatibility with existing PCB layouts and connector interfaces.

Color Specification: Green color (x 10) is required to maintain consistent visual indication characteristics across the application.

Lens Style: Rectangle with Flat Top lens geometry must be preserved to ensure optical performance and physical fit within the application enclosure.

Electrical Parameters: While voltage rating and current specifications may vary within acceptable operating ranges for LED indicators, the substitute must support the intended circuit design. The wavelength peak may differ due to manufacturing variations in green LED technology.

Compliance Requirements: RoHS compliance status and Moisture Sensitivity Level 1 classification are maintained across qualified substitutes.

The Lite-On Inc. model LTA-1000G meets these substitution criteria through matching configuration, color, and lens style specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: The Lite-On Inc. LTA-1000G is the qualified substitute for the obsolete Seeed 104990108. Both components share identical configuration (Bar - 10 Wide, DIP), color specification (Green x 10), and lens style (Rectangle with Flat Top).

Product Status Advantage: The LTA-1000G maintains Active product status with current manufacturing availability (2320 Pcs in stock), providing long-term supply continuity compared to the obsolete 104990108.

Compliance Certification: Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification and comply with RoHS requirements. The LTA-1000G carries ROHS3 Compliant and REACH Affected designations, meeting current regulatory standards.

Electrical Parameter Differences: The LTA-1000G operates at lower voltage (2.1V vs 3.2V) and current (25mA vs 100mA) specifications. Circuit design modifications may be required to accommodate these electrical differences. The wavelength peak differs (569nm vs 514nm), representing a shift within the green spectrum range.

Brightness Consideration: The LTA-1000G provides significantly lower brightness (2mcd vs 250mcd). Applications requiring high brightness indication may require design evaluation.

Frequently Asked Questions (FAQ)

Q: Can the LTA-1000G directly replace the 104990108 without circuit modifications?

A: Both parts share identical mechanical configuration (Bar - 10 Wide, DIP) and lens style (Rectangle with Flat Top), enabling direct physical substitution. However, the LTA-1000G operates at different electrical specifications (2.1V/25mA vs 3.2V/100mA). Circuit design review is necessary to confirm compatibility with existing power supply and current-limiting resistor values.

Q: What is the significance of the wavelength difference between 514nm and 569nm?

A: Both wavelengths fall within the green spectrum range for LED indicators. The 514nm wavelength (104990108) represents a more pure green, while 569nm (LTA-1000G) represents a yellow-green appearance. Visual perception differences may occur in the application environment.

Q: Why is the brightness rating significantly lower for the LTA-1000G?

A: The LTA-1000G is rated at 2mcd compared to 250mcd for the 104990108. This difference reflects the lower operating current (25mA vs 100mA) and may impact visibility in high-ambient-light environments. Application brightness requirements must be evaluated.

Q: Are both parts suitable for new designs?

A: The 104990108 is classified as obsolete and should not be selected for new designs. The LTA-1000G maintains Active product status and is appropriate for new design implementations requiring a 10-segment green LED bar indicator.

Q: What packaging differences exist between these parts?

A: The 104990108 is specified with DIP package format. The LTA-1000G is supplied in Tube packaging with Through Hole mounting type, consistent with DIP component handling and installation methods.
