SSA-LXB102YD LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The SSA-LXB102YD is a 10-segment LED circuit board indicator manufactured by Lumex Opto/Components Inc. This component features a 3mm round lens with domed top, yellow color output at 585nm peak wavelength, and is designed for through-hole mounting applications. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility for circuit board indicator applications requiring 10-wide LED configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSA-LXB102YD is determined by the following critical parameters that must remain consistent:

Mandatory Matching Parameters:

• Color: Yellow (x 10)
• Wavelength - Peak: 585nm
• Configuration: 10 Wide
• Voltage Rating: 2.1V
• Current: 30mA
• Mounting Type: Through Hole
• Lens Type: Diffused, Tinted
• Manufacturer: Lumex Opto/Components Inc.

Allowable Variation Parameters:

• Lens Style (Round with Domed Top vs. Rectangle with Flat Top)
• Lens Size (3mm T-1 vs. 5.00mm x 2.50mm)
• Millicandela Rating (8mcd vs. 10mcd)
• Viewing Angle (80° vs. 110°)
• Product Status (Obsolete vs. Active)

The SSA-LXH1025YD qualifies as a substitute because it maintains all mandatory parameters while offering improved specifications in brightness and viewing angle, with the trade-off of different physical form factor (rectangular vs. round lens).

Parameter Comparison

Engineering Selection Recommendations

The SSA-LXH1025YD serves as the primary substitute for the obsolete SSA-LXB102YD. Both components maintain identical electrical specifications (2.1V, 30mA) and optical characteristics (585nm yellow wavelength, diffused tinted lens). The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Key considerations for selection:

Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

Electrical Compatibility: Identical voltage and current ratings ensure direct functional substitution in circuit designs without modification to drive circuitry.

Physical Form Factor: The SSA-LXH1025YD features a rectangular lens (5.00mm x 2.50mm) compared to the round 3mm lens of the original part. PCB layout and mechanical mounting must accommodate this dimensional change.

Optical Performance: The substitute provides improved brightness (10mcd vs. 8mcd) and wider viewing angle (110° vs. 80°), offering enhanced visibility characteristics.

Frequently Asked Questions (FAQ)

Q: Can the SSA-LXH1025YD directly replace the SSA-LXB102YD without circuit modification?

A: Yes. Both parts operate at identical voltage (2.1V) and current (30mA) specifications. No changes to drive circuitry are required. However, PCB layout modifications may be necessary due to different physical dimensions.

Q: What is the primary difference between these two parts?

A: The main differences are physical form factor and optical performance. The SSA-LXB102YD uses a 3mm round lens with 80° viewing angle, while the SSA-LXH1025YD uses a 5.00mm x 2.50mm rectangular lens with 110° viewing angle. Both maintain identical electrical specifications and wavelength output.

Q: Why is the SSA-LXB102YD listed as obsolete?

A: The SSA-LXB102YD is classified as obsolete by the manufacturer. The SSA-LXH1025YD represents the active equivalent in Lumex's current product portfolio for 10-segment yellow LED circuit board indicator applications.

Q: Are there any compliance concerns with substitution?

A: No. Both parts maintain ROHS3 compliance and REACH unaffected status. Regulatory and environmental compliance requirements are equivalent between the two components.

Q: What mounting considerations apply to the substitute part?

A: Both parts use through-hole mounting. The SSA-LXH1025YD requires PCB footprint modifications due to its rectangular lens geometry (5.00mm x 2.50mm) compared to the round 3mm lens of the original part. Verify PCB layout compatibility before implementation.

Q: Does the improved brightness of the substitute part affect circuit design?

A: No. The substitute part operates at the same 30mA current specification. The increased brightness (10mcd vs. 8mcd) results from improved LED efficiency, not increased current draw. Existing drive circuits remain compatible.
