OPXP1SDIF Equivalent & Substitute Parts

Part Overview

The OPXP1SDIF is a lens with integrated mount manufactured by Dialight, designed for use with Cree LEDs. This clear polycarbonate lens features a 14° spot optical pattern and adhesive mounting. The part is currently obsolete, making identification of suitable substitute components essential for ongoing applications and design updates. Substitute parts must maintain compatibility across optical performance, mechanical mounting, and material specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPXP1SDIF is determined by the following critical parameters:

• Optical Pattern: Must be Spot
• Mounting Type: Must be Adhesive
• Material: Must be Polycarbonate
• Color: Must be Clear
• Lens Style: Must be Round with Flat Top
• Number of LEDs: Must be 1
• Series Compatibility: OPX series preferred for direct compatibility

The OPXC1SPOT qualifies as a substitute based on matching optical pattern (Spot), mounting type (Adhesive), material (Polycarbonate), color (Clear), lens style (Round with Flat Top), and single LED configuration. The primary difference is the viewing angle specification: OPXC1SPOT provides a 12° viewing angle compared to the 14° of the OPXP1SDIF. This represents a narrower beam concentration and must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

The OPXC1SPOT is the qualified substitute for the obsolete OPXP1SDIF based on matching core mechanical and optical specifications. Both components share identical mounting methodology (adhesive), material composition (polycarbonate), lens geometry (round with flat top), and optical classification (spot pattern). Both maintain MSL 1 rating and REACH Unaffected status.

The OPXC1SPOT offers the advantage of active product status, ensuring continued availability and supply chain reliability. The component also supports expanded LED manufacturer compatibility (Cree, Lumileds, Nichia) compared to the OPXP1SDIF specification limited to Cree.

The primary technical distinction is the viewing angle: OPXC1SPOT specifies 12° versus the OPXP1SDIF's 14°. This represents a 2° reduction in beam divergence, resulting in a more concentrated optical output. Applications requiring the original 14° beam spread must evaluate whether the narrower 12° pattern remains acceptable for the intended use case.

Frequently Asked Questions (FAQ)

Q: Can OPXC1SPOT directly replace OPXP1SDIF in existing assemblies?

A: Mechanical and mounting compatibility is confirmed. Both components use adhesive mounting, identical lens geometry, and polycarbonate construction. The optical difference (12° versus 14° viewing angle) must be validated against application requirements before substitution.

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

A: Viewing angle defines beam divergence. The OPXC1SPOT's 12° angle produces a more concentrated beam compared to the OPXP1SDIF's 14° angle. Applications sensitive to beam spread or light distribution patterns require evaluation of this parameter.

Q: Why is OPXP1SDIF obsolete?

A: Product status reflects manufacturer discontinuation. The OPXC1SPOT represents the active equivalent within the OPX series, providing continued access to functionally compatible lens solutions.

Q: Are there packaging differences between these parts?

A: OPXP1SDIF packaging is specified as dash (unspecified). OPXC1SPOT is supplied in Bulk packaging. Procurement requirements should account for packaging format differences.

Q: Does OPXC1SPOT support the same LED manufacturers?

A: OPXC1SPOT supports Cree, Lumileds, and Nichia. OPXP1SDIF specification lists Cree. The broader compatibility of OPXC1SPOT provides additional design flexibility.

Q: Are compliance certifications identical?

A: Both components maintain MSL 1 (Unlimited) rating, REACH Unaffected status, and EAR99 ECCN classification. OPXC1SPOT adds RoHS3 Compliance certification. Compliance requirements are satisfied by either component.
