Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FP10998_LISA2-M-PIN is determined by the following critical parameters:

Mechanical Compatibility: Lens size (9.9mm Dia), lens style (Round with Flat Top), mounting type (Adhesive), and material (Acrylic) must remain constant across substitute parts.

Optical Characteristics: The optical pattern (Medium) and color (Clear) define the light distribution and transmission properties and must be preserved.

Electrical & Environmental Compliance: RoHS3 compliance, MSL rating (1 - Unlimited), and REACH unaffected status establish regulatory and environmental operating boundaries.

Series Consistency: Parts must belong to the LISA2 series to ensure mechanical and optical alignment with existing designs.

Viewing Angle Tolerance: The primary distinction in substitute parts is the viewing angle specification. The FP10998_LISA2-M-PIN operates at a fixed 26° viewing angle. Substitute parts with viewing angle ranges that encompass 26° (such as 25° ~ 35°) are functionally equivalent within the specified tolerance band.

Parameter Comparison

Engineering Selection Recommendations

FP10992_LISA2-M-PIN is the designated substitute for FP10998_LISA2-M-PIN based on the following criteria:

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring continued adherence to environmental and regulatory requirements.

Product Status: The FP10992_LISA2-M-PIN is classified as Active, providing assured long-term availability and supply chain continuity compared to the obsolete FP10998_LISA2-M-PIN.

Mechanical & Optical Equivalence: All critical mechanical parameters (lens size, style, material, mounting type) and optical characteristics (color, pattern) are identical between the two parts.

Viewing Angle Specification: The FP10992_LISA2-M-PIN specifies a viewing angle range of 25° ~ 35°, which encompasses the 26° specification of the FP10998_LISA2-M-PIN. This range-based specification provides equivalent optical performance within the design tolerance.

Environmental Rating: Both parts share identical MSL rating (1 - Unlimited), confirming equivalent moisture sensitivity performance.

Frequently Asked Questions (FAQ)

Q: Why is FP10992_LISA2-M-PIN considered a substitute for FP10998_LISA2-M-PIN?

A: The FP10992_LISA2-M-PIN maintains identical mechanical construction (9.9mm diameter round lens with flat top, acrylic material, adhesive mounting), optical characteristics (clear color, medium pattern), and environmental compliance (ROHS3, MSL 1). The viewing angle specification of 25° ~ 35° encompasses the 26° specification of the main part, providing functional equivalence.

Q: What is the difference in viewing angle specification between these parts?

A: The FP10998_LISA2-M-PIN specifies a fixed 26° viewing angle, while the FP10992_LISA2-M-PIN specifies a range of 25° ~ 35°. The range-based specification of the substitute part includes the 26° value within its tolerance band, ensuring optical performance compatibility.

Q: Are there any compatibility concerns with LED manufacturers?

A: The FP10998_LISA2-M-PIN is specified for use with Nichia LEDs. The FP10992_LISA2-M-PIN is compatible with both Lumileds and Nichia LEDs, providing broader compatibility while maintaining performance with the original specified manufacturer.

Q: What is the packaging difference?

A: The FP10998_LISA2-M-PIN packaging is not specified. The FP10992_LISA2-M-PIN is supplied in Bag packaging. This difference does not affect component performance or mechanical compatibility.

Q: Is the FP10992_LISA2-M-PIN available for immediate use?

A: Yes. The FP10992_LISA2-M-PIN is classified as Active product status with 960 pieces in stock, ensuring supply availability. The FP10998_LISA2-M-PIN is obsolete, making the substitute part the recommended selection for new designs and ongoing production.
