Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FP11057_LISA2-RS-PIN is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Series platform: LISA2
• Lens diameter: 9.9mm
• Lens style: Round with Flat Top
• Color: Clear
• Number of LEDs: 1
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

Allowable Variation Parameters:

• Optical pattern: Elliptical/Oval to Spot
• Viewing angle: 18° (fixed) to 18° ~ 24° (range)
• Mounting type: Pin-based to Adhesive
• Product status: Obsolete to Active

The FP11056_LISA2-RS-PIN qualifies as a direct substitute within the LISA2 platform, maintaining identical lens geometry and regulatory compliance while offering an active product status and extended viewing angle range.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: FP11056_LISA2-RS-PIN

The FP11056_LISA2-RS-PIN is the designated substitute for the obsolete FP11057_LISA2-RS-PIN. Both components maintain identical LISA2 series platform compatibility, lens geometry (9.9mm diameter, round with flat top), and regulatory certifications (ROHS3 Compliant, REACH Unaffected, MSL 1).

The FP11056_LISA2-RS-PIN offers the advantage of active product status, ensuring continued availability and supply chain reliability. The component is compatible with Lumileds and Nichia LED sources, consistent with the original part's Nichia compatibility specification.

Differences in optical pattern (Spot versus Elliptical/Oval) and viewing angle range (18° ~ 24° versus fixed 18°) represent functional variations that must be evaluated against specific application requirements. The adhesive mounting type of the substitute differs from the pin-based mounting of the original part, requiring mechanical integration assessment.

Frequently Asked Questions (FAQ)

Q: Can FP11056_LISA2-RS-PIN directly replace FP11057_LISA2-RS-PIN in existing assemblies?

A: Both components share the LISA2 platform, identical lens diameter (9.9mm), and regulatory compliance. However, the mounting type differs (adhesive versus pin-based), requiring mechanical redesign of the mounting interface. The optical pattern and viewing angle specifications also differ and must be validated against application performance requirements.

Q: What are the key compatibility factors for LISA2 series lens substitution?

A: Compatibility is determined by series platform (LISA2), lens diameter (9.9mm), lens style (round with flat top), color (clear), single LED configuration, and regulatory compliance (ROHS3, REACH). Variations in optical pattern, viewing angle, and mounting type are allowable within the series but require application-specific validation.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both FP11057_LISA2-RS-PIN and FP11056_LISA2-RS-PIN are ROHS3 Compliant and REACH Unaffected, with MSL rating of 1 (Unlimited), meeting current regulatory standards for electronic component manufacturing and distribution.

Q: What is the inventory status of these components?

A: FP11057_LISA2-RS-PIN (obsolete) has 1065 pieces in stock. FP11056_LISA2-RS-PIN (active) has 781 pieces in stock. Availability of the active substitute ensures continued supply for new designs and production requirements.

Q: How do the optical patterns differ between these components?

A: FP11057_LISA2-RS-PIN provides an elliptical/oval optical pattern with a fixed 18° viewing angle. FP11056_LISA2-RS-PIN provides a spot optical pattern with an 18° ~ 24° viewing angle range. These differences affect light distribution characteristics and must be evaluated for specific application requirements.
