Dialight 5151061 Light Pipe - Equivalent & Substitute Parts

Part Overview

The Dialight 5151061 is a light pipe assembly designed for 2 high configuration applications with a 3mm round lens and flat top. This component features rigid board mount construction with press-fit installation. The part is classified as obsolete, making identification of compatible substitute components essential for ongoing production and maintenance applications. Substitute parts must maintain functional equivalence in optical performance, mechanical mounting, and electrical characteristics while accommodating modern component availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the 5151061 is based on the following critical parameters that define functional compatibility:

Configuration (2 High): Substitute parts must maintain the same stack height configuration to ensure proper alignment with PCB layouts and optical path requirements.

Lens Style (Round with Flat Top): The optical geometry must remain consistent to preserve light transmission characteristics and mechanical fit within lens cavities.

Type (Rigid): Material composition and structural properties must match to maintain dimensional stability and thermal performance.

Mounting Type (Board Mount, Press Fit): Installation method compatibility ensures proper mechanical retention and electrical continuity.

Color (Clear): Optical transmission properties must be preserved for consistent light pipe performance.

The identified substitute part 5151061F shares the core configuration, lens style, type, mounting method, and color characteristics. Variations in lens size (4.3mm vs 3mm), mounting angle (right angle addition), and product status (active vs obsolete) are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

The 5151061F serves as an active substitute for the obsolete 5151061. Both parts share identical series designation, configuration, lens style, type, mounting method, and color characteristics. The 5151061F maintains REACH compliance and achieves ROHS3 certification, providing enhanced regulatory alignment for new designs and production continuity.

Lens size variation (4.3mm vs 3mm) and the addition of right angle mounting capability in the 5151061F represent design enhancements. These differences require mechanical verification against specific PCB cavity dimensions and optical path requirements in the target application.

The active product status of 5151061F ensures ongoing availability and supply chain reliability compared to the obsolete 5151061.

Frequently Asked Questions (FAQ)

Q: Can 5151061F directly replace 5151061 in existing designs?

A: Both parts share the same configuration, lens style, type, mounting method, and color. However, the 4.3mm lens size of 5151061F differs from the 3mm lens size of 5151061. Mechanical fit within PCB cavities and optical performance must be verified for the specific application before implementation.

Q: What is the significance of the right angle mounting option in 5151061F?

A: The 5151061F includes right angle mounting capability in addition to standard board mount press-fit installation. This provides additional installation flexibility but does not affect compatibility with applications requiring standard board mount orientation.

Q: Are there compliance differences between these parts?

A: The 5151061F achieves ROHS3 compliance and specifies MSL 1 (Unlimited), whereas the 5151061 lists RoHS status as not applicable and MSL as not applicable. Both parts maintain REACH unaffected status and identical ECCN and HTSUS classifications.

Q: What packaging options are available?

A: The 5151061 is supplied in standard packaging, while 5151061F is available in bulk packaging format.

Q: Why is the 5151061 classified as obsolete?

A: The 5151061 is no longer in active production. The 5151061F represents the current active equivalent within the Dialight 515 series, ensuring continued availability for applications requiring this component category.
