Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSA-LXB102SRD is determined by the following critical parameters that must remain compatible:

Electrical Parameters (Non-Negotiable):

• Voltage Rating: 1.7V
• Current Rating: 30mA
• Wavelength - Peak: 660nm (red spectrum)
• Configuration: 10-segment wide arrangement

Mechanical Parameters (Application-Dependent):

• Mounting Type: Through Hole
• Lens Type: Diffused, Tinted
• Color: Red (x 10)

Compliance Parameters:

• RoHS3 Compliance
• REACH Unaffected Status
• MSL Rating: 1 (Unlimited)

The SSA-LXH1025SRD qualifies as a substitute based on matching electrical specifications (1.7V, 30mA, 660nm, 10-segment configuration) and compliance certifications. Differences in lens geometry (rectangular vs. round), millicandela rating (50mcd vs. 25mcd), and viewing angle (110° vs. 80°) represent enhanced performance characteristics rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

The SSA-LXH1025SRD serves as a direct electrical substitute for the obsolete SSA-LXB102SRD. Both components maintain identical voltage (1.7V) and current (30mA) specifications, ensuring circuit compatibility without modification to drive electronics or current-limiting resistor calculations.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new production and repair applications.

Performance Considerations: The substitute part delivers enhanced brightness (50mcd vs. 25mcd) and wider viewing angle (110° vs. 80°), representing performance improvements rather than degradation. These enhancements do not introduce incompatibility with existing circuit designs.

Physical Form Factor: The primary difference lies in lens geometry. The SSA-LXB102SRD features a 3mm round domed lens, while the SSA-LXH1025SRD employs a 5.00mm x 2.50mm rectangular flat-top lens. PCB layout and mechanical mounting considerations must account for this dimensional change.

Active Product Status: The SSA-LXH1025SRD maintains active product status with confirmed inventory availability (791 pcs), ensuring long-term supply chain reliability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the SSA-LXH1025SRD directly replace the SSA-LXB102SRD without circuit modification?

A: Yes. Both components operate at identical electrical specifications (1.7V, 30mA, 660nm). No changes to drive circuitry, current-limiting resistors, or voltage regulation are required.

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

A: The SSA-LXB102SRD uses a 3mm round lens with domed top, while the SSA-LXH1025SRD uses a 5.00mm x 2.50mm rectangular lens with flat top. PCB footprint and mounting hole spacing will differ, requiring layout modification.

Q: Does the higher millicandela rating (50mcd vs. 25mcd) of the substitute create compatibility issues?

A: No. The increased brightness represents enhanced performance. If the original design relied on the 25mcd output for specific optical characteristics, the 50mcd output will provide greater visibility without introducing electrical incompatibility.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the SSA-LXB102SRD and SSA-LXH1025SRD are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations.

Q: Why is the substitute part recommended despite physical differences?

A: The SSA-LXB102SRD is obsolete with no active production. The SSA-LXH1025SRD provides identical electrical functionality with active product status and confirmed inventory, ensuring design continuity and supply chain reliability.

Q: Will the wider viewing angle (110° vs. 80°) affect circuit performance?

A: No. A wider viewing angle represents an enhancement that increases visibility from additional angles. This does not degrade circuit performance or introduce electrical incompatibility.

Q: What mounting considerations apply when switching to the SSA-LXH1025SRD?

A: Both parts use through-hole mounting. However, the rectangular lens geometry and different physical dimensions require PCB layout revision to accommodate the new footprint and ensure proper mechanical alignment.
