Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSA-LXB102GD is determined by the following critical parameters that must align across equivalent components:

Electrical Compatibility Parameters:

• Operating voltage (2.21V nominal)
• Current consumption (25mA)
• Peak wavelength (565nm green spectrum)
• 10-segment configuration

Optical Performance Parameters:

• Luminous intensity (8mcd minimum)
• Lens type (diffused, tinted)
• Color specification (green)

Mechanical & Mounting Parameters:

• Through-hole mounting requirement
• Lens material and optical properties
• Physical form factor compatibility with PCB layout

Compliance & Regulatory Parameters:

• RoHS3 compliance
• REACH unaffected status
• MSL rating (1 - Unlimited)

The substitute part SSA-LXH1025GD shares the same manufacturer, electrical specifications (25mA, 2.2V, 565nm), optical properties (green, diffused tinted lens), mounting type (through-hole), and regulatory compliance status. Differences in physical form factor (rectangular 5.00mm x 2.50mm versus round 3.00mm) and configuration style (bar SIP versus individual segments) require PCB layout evaluation.

Engineering Selection Recommendations

Primary Substitute: SSA-LXH1025GD

The SSA-LXH1025GD is the designated equivalent for the obsolete SSA-LXB102GD based on the following engineering criteria:

Electrical Equivalence: Both components operate at nominally identical voltage (2.21V vs 2.2V) and current (25mA), with matching peak wavelength (565nm) and green color specification. These parameters ensure direct functional replacement in circuit operation.

Optical Performance: The substitute delivers 10mcd luminous intensity compared to the original 8mcd, representing a performance enhancement. The 110° viewing angle exceeds the original 80°, providing improved visibility characteristics. Both components utilize diffused, tinted lens technology for identical optical diffusion properties.

Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited), ensuring compatibility with current manufacturing and environmental standards.

Active Product Status: The SSA-LXH1025GD is classified as active with 4913 units in stock, providing reliable supply chain availability compared to the obsolete status of the original part.

Design Consideration: The substitute features a rectangular form factor (5.00mm x 2.50mm) with SIP bar configuration versus the original round 3.00mm diameter design. PCB layout modification is required to accommodate the different physical dimensions and mounting footprint. The bar configuration consolidates 10 segments into a single SIP package, potentially reducing board space complexity depending on application requirements.

Frequently Asked Questions (FAQ)

Q: Can SSA-LXH1025GD directly replace SSA-LXB102GD without circuit modification?

A: Electrical and optical parameters are compatible. However, the different physical form factor (rectangular bar versus round individual segments) requires PCB layout redesign. The mounting footprint, hole spacing, and component placement differ significantly.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Operating voltage (2.21V/2.2V), current consumption (25mA), peak wavelength (565nm), and color specification (green) are the primary electrical criteria. Both parts meet these requirements identically.

Q: Does the higher millicandela rating (10mcd vs 8mcd) of the substitute create compatibility issues?

A: No. The substitute's higher luminous intensity represents improved optical performance and does not create incompatibility. Circuit current limiting remains at 25mA for both components.

Q: Are there compliance differences between the main part and substitute?

A: No. Both components maintain identical RoHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited), ensuring regulatory equivalence.

Q: What is the primary reason for substitution?

A: The SSA-LXB102GD is classified as obsolete. The SSA-LXH1025GD is an active product with confirmed inventory availability, ensuring long-term supply chain continuity.

Q: How does the viewing angle difference (80° vs 110°) affect application suitability?

A: The substitute's wider 110° viewing angle provides enhanced visibility from off-axis positions. This represents a performance improvement for applications requiring wide-angle visibility. No negative compatibility impact exists.

Q: What design changes are necessary to implement the substitute?

A: PCB layout modification is required to accommodate the rectangular 5.00mm x 2.50mm form factor and SIP bar configuration. Through-hole mounting remains consistent, but hole spacing and component placement differ from the original round 3.00mm design.
