Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPGD1427S is determined by the following critical parameters:

• Optical Pattern: Elliptical/Oval configuration required for beam shaping consistency
• Color: Clear lens specification for unfiltered light transmission
• Number of LEDs: Single LED compatibility (1)
• Lens Style: Round with Flat Top geometry
• Type Classification: Sub Lens category for integrated optical assemblies
• Regulatory Compliance: REACH and ECCN classifications for supply chain continuity

The identified substitute part OPAA1OSL shares the core optical and functional characteristics necessary for component replacement, though with dimensional and material variations that must be evaluated within specific application contexts.

Parameter Comparison

Engineering Selection Recommendations

The OPAA1OSL substitute part is classified as Active product status, providing supply chain continuity for the obsolete OPGD1427S. Both components maintain identical regulatory compliance profiles (REACH Unaffected, EAR99 classification) and equivalent moisture sensitivity ratings (MSL 1).

Key considerations for component selection:

• Dimensional Compatibility: The OPAA1OSL features a 26mm diameter lens compared to the 50mm diameter of the OPGD1427S. This dimensional difference requires mechanical integration verification within the target assembly.
• Mounting Interface: The OPAA1OSL incorporates snap-in mounting, whereas the OPGD1427S mounting type is not specified. Assembly compatibility must be confirmed.
• Material Specification: The OPAA1OSL is manufactured from acrylic material, providing consistent optical clarity and environmental stability.
• Optical Characteristics: Both components share elliptical/oval optical patterns and clear color specifications, maintaining beam shaping functionality.

Frequently Asked Questions (FAQ)

Q: Can OPAA1OSL directly replace OPGD1427S in existing assemblies?

A: Direct replacement requires verification of mechanical mounting interfaces and dimensional compatibility. The 26mm diameter of OPAA1OSL differs significantly from the 50mm diameter of OPGD1427S, necessitating assembly design review.

Q: What are the key substitution criteria for this lens category?

A: Substitution eligibility is based on optical pattern (elliptical/oval), color (clear), LED count (1), lens style (round with flat top), and regulatory compliance status (REACH and ECCN classifications).

Q: Are there compliance differences between these parts?

A: Both components maintain identical regulatory classifications: REACH Unaffected and EAR99 ECCN designation. Moisture sensitivity levels are equivalent (MSL 1).

Q: What is the viewing angle specification for OPAA1OSL?

A: The OPAA1OSL provides an 8° x 54° viewing angle with diffused lens transparency, differing from the OPGD1427S which does not specify viewing angle parameters.

Q: Is OPAA1OSL RoHS compliant?

A: Yes, OPAA1OSL is ROHS3 compliant, supporting environmental and regulatory requirements for modern electronic assemblies.

Q: What packaging options are available for the substitute part?

A: OPAA1OSL is supplied in bulk packaging, suitable for production and assembly operations.
