OPC11COLWD Equivalent & Substitute Parts

Part Overview

The OPC11COLWD is a reflector component manufactured by Dialight, designed for use with Lumileds light sources. This round, 11.5mm adhesive-mounted reflector features a 26° wide optical pattern and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts is essential for maintaining design continuity and ensuring component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPC11COLWD are identified based on the following critical parameters that determine functional equivalence:

• Manufacturer and Series: Both parts must be from Dialight OPC series to ensure design compatibility
• Physical Form Factor: Style and size must remain Round, 11.5mm to fit existing mechanical assemblies
• Mounting Method: Adhesive mounting type must be maintained for assembly process compatibility
• Optical Characteristics: Wide optical pattern classification and viewing angle specifications determine light distribution properties
• Compatibility: Parts must be designated for use with Lumileds light sources
• Environmental Compliance: Moisture sensitivity level and REACH status must meet or exceed original specifications

The OPC12COL is identified as a substitute part within the OPC series, maintaining the same physical form factor, mounting method, and optical pattern classification while operating within the same environmental compliance framework.

Parameter Comparison

Engineering Selection Recommendations

The OPC12COL serves as an active substitute for the obsolete OPC11COLWD. Both components share identical physical dimensions (Round, 11.5mm), mounting methodology (Adhesive), and environmental compliance classifications (MSL 1, REACH Unaffected, ECCN EAR99). The OPC12COL maintains active product status, ensuring ongoing availability and supply chain continuity.

The primary technical difference between these parts is the viewing angle specification: OPC11COLWD operates at 26° while OPC12COL operates at 13°. This difference in viewing angle affects light distribution characteristics and must be evaluated against specific application requirements. Both parts maintain the Wide optical pattern classification and are compatible with Lumileds light sources.

Selection of OPC12COL as a replacement for OPC11COLWD is supported by equivalent environmental compliance, identical form factor and mounting specifications, and active manufacturing status.

Frequently Asked Questions (FAQ)

Q: Can OPC12COL directly replace OPC11COLWD in existing assemblies?

A: Both parts share identical physical dimensions (Round, 11.5mm) and mounting type (Adhesive), allowing mechanical compatibility. However, the viewing angle differs (26° versus 13°), which affects optical performance. Application-specific requirements must be evaluated to determine functional suitability.

Q: Why is OPC11COLWD listed as obsolete?

A: OPC11COLWD has been discontinued by Dialight. OPC12COL is the active equivalent within the OPC series, providing continued availability for component sourcing.

Q: Are there environmental or compliance differences between these parts?

A: Both parts share identical environmental classifications: Moisture Sensitivity Level 1 (Unlimited), REACH Unaffected status, and ECCN EAR99. No compliance differences exist between the two components.

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

A: Viewing angle (26° for OPC11COLWD versus 13° for OPC12COL) determines the angular distribution of light from the reflector. The 26° specification provides a wider light distribution, while the 13° specification provides a narrower, more focused distribution. Application optical requirements must be verified before substitution.

Q: Are both parts compatible with Lumileds light sources?

A: Yes, both OPC11COLWD and OPC12COL are designated for use with Lumileds light sources and maintain this compatibility specification.

Q: What packaging is available for OPC12COL?

A: OPC12COL is available in Bulk packaging, with 5017 pieces in current inventory stock.
