OPC11SDIF Equivalent & Substitute Parts

Part Overview

The OPC11SDIF is a lens with integrated mount manufactured by Dialight, designed for single LED applications with clear optical properties and adhesive mounting. This component features a 22mm diameter round lens with a flat top and a 14° viewing angle, optimized for use with Lumileds LED sources. The product is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPC11SDIF is based on the following critical parameters that define functional equivalence:

Core Compatibility Criteria:

• Single LED lens configuration (Number of LEDs = 1)
• Polycarbonate material composition
• Adhesive mounting mechanism
• Clear optical color
• Round lens geometry with flat top profile

Optical Performance Considerations: The OPC11SDIF operates with a 14° viewing angle and diffused transparency. Substitute components must maintain compatibility with the same LED source family (Lumileds) and preserve the adhesive mounting interface. The OPXC1SPOT substitute shares the core mechanical and material specifications but introduces a narrower 12° viewing angle with spot optical pattern characteristics, representing a tighter beam concentration suitable for applications requiring increased directional intensity.

Parameter Comparison

Engineering Selection Recommendations

The OPXC1SPOT represents the primary substitute option for the obsolete OPC11SDIF. Both components share identical material composition, mounting methodology, and regulatory compliance frameworks. The OPXC1SPOT maintains active product status with ROHS3 compliance, ensuring continued availability and regulatory alignment for new designs.

The primary optical difference—12° viewing angle versus 14° and spot pattern versus diffused transparency—reflects a design shift toward narrower beam concentration. This substitution is appropriate for applications where tighter optical control is acceptable or beneficial. The OPXC1SPOT's compatibility with multiple LED manufacturers (Cree, Lumileds, Nichia) provides broader sourcing flexibility compared to the OPC11SDIF's Lumileds specification.

Both components maintain identical moisture sensitivity ratings and REACH compliance status, eliminating environmental or storage requirement changes during transition.

Frequently Asked Questions (FAQ)

Q: Can OPXC1SPOT directly replace OPC11SDIF in existing assemblies?

A: Mechanical and material compatibility is confirmed. The adhesive mounting interface and polycarbonate construction are identical. Optical performance differs due to the 12° versus 14° viewing angle and spot versus diffused pattern. Application-specific testing is necessary to confirm optical performance acceptability.

Q: What is the significance of the viewing angle difference?

A: The OPC11SDIF provides a 14° viewing angle with diffused light distribution. The OPXC1SPOT narrows this to 12° with spot concentration. This results in increased intensity within a narrower beam cone, suitable for applications requiring directional focus rather than broad illumination.

Q: Are there packaging differences between these components?

A: The OPC11SDIF is specified with dash packaging notation. The OPXC1SPOT is supplied in bulk packaging. Procurement and handling procedures may require adjustment accordingly.

Q: Do both components meet current regulatory requirements?

A: Yes. Both maintain REACH Unaffected status and RoHS compliance. The OPXC1SPOT carries ROHS3 certification, representing the current regulatory standard. Both components have MSL 1 ratings, indicating unlimited shelf life under standard storage conditions.

Q: What LED manufacturers are compatible with each component?

A: The OPC11SDIF is specified for Lumileds sources. The OPXC1SPOT extends compatibility to Cree, Lumileds, and Nichia LED families, providing broader design flexibility for new implementations.
