Substitute Part Grouping Explanation

Substitution eligibility for the LP368PWN1-D0G is determined by the following critical parameters:

Package Compatibility: All substitutes must use 4-DIP (0.200", 5.08mm) through-hole packaging to ensure PCB footprint compatibility
Electrical Specifications: Forward voltage (Vf) must be within the 4.6V to 3.6V range; test current must be 20mA to 30mA to maintain circuit design integrity
Color and Lens Properties: White color with clear lens transparency required for functional equivalence
Mounting Configuration: Through-hole mounting type mandatory for direct replacement in existing designs
Environmental Compliance: MSL rating of 1 (Unlimited) and REACH Unaffected status required for supply chain consistency

The identified substitute parts meet these core criteria while maintaining functional compatibility with the original LP368PWN1-D0G specification.

Engineering Selection Recommendations

OVFSW6C8 (TT Electronics / Optek Technology) is an active product with identical forward voltage (3.6V) and test current (30mA) specifications. This substitute maintains electrical compatibility with existing circuit designs. The component carries ROHS3 compliance certification and unlimited moisture sensitivity rating, ensuring supply chain reliability. Mechanical differences include a 3.00mm round domed lens versus the original 7.60mm square flat-top lens, and increased height (6.15mm vs. 4.85mm), which may require PCB layout verification for clearance constraints.

SSL-LX30448UWC (Lumex Opto/Components Inc.) is an active product with forward voltage of 4.6V and reduced test current of 20mA. This component offers higher brightness (500mcd vs. 400mcd) and includes peak wavelength specification (550nm). ROHS3 compliance and unlimited moisture sensitivity rating are provided. Mechanical differences include a 3.00mm round domed lens, increased height (6.30mm vs. 4.85mm), and significantly reduced viewing angle (30° vs. 130°), which may impact application suitability for wide-angle indication requirements.

Both substitutes are active products with current manufacturing support, addressing the obsolescence status of the LP368PWN1-D0G.

Frequently Asked Questions (FAQ)

Q: Can OVFSW6C8 and SSL-LX30448UWC be used interchangeably with LP368PWN1-D0G?

A: Both parts share the same 4-DIP through-hole package and clear white lens properties. However, mechanical and optical differences exist. OVFSW6C8 maintains identical electrical parameters (3.6V, 30mA) but features a smaller round lens and greater height. SSL-LX30448UWC operates at 4.6V with 20mA test current and offers higher brightness but significantly narrower viewing angle (30° vs. 130°). Application requirements determine suitability.

Q: What are the key differences in lens design between these parts?

A: The LP368PWN1-D0G features a 7.60mm square lens with flat top. OVFSW6C8 and SSL-LX30448UWC both use 3.00mm round lenses with domed tops. These differences affect light distribution, viewing angle, and physical footprint on the PCB.

Q: Are all three parts compliant with environmental regulations?

A: Yes. All three components carry REACH Unaffected status and MSL rating of 1 (Unlimited). OVFSW6C8 and SSL-LX30448UWC additionally carry ROHS3 compliance certification.

Q: What is the impact of viewing angle differences?

A: The LP368PWN1-D0G provides 130° viewing angle for wide-area indication. OVFSW6C8 offers 60° viewing angle, and SSL-LX30448UWC offers 30° viewing angle. Applications requiring wide-angle visibility may not be suitable for the narrower-angle substitutes.

Q: How do the height differences affect PCB design?

A: The LP368PWN1-D0G has a maximum height of 4.85mm. OVFSW6C8 reaches 6.15mm, and SSL-LX30448UWC reaches 6.30mm. PCB clearance above the component must be verified to accommodate the increased height of substitute parts.
