ELM 4-105 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-105 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.105" (2.67mm) height. This component is constructed from black PVC material and accommodates 2-lead configurations. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments.

Substitute parts become necessary when the primary component experiences inventory constraints, extended lead times, or when design flexibility permits dimensional variation within acceptable mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-105 is determined by the following critical parameters:

Mandatory Matching Parameters:

• LED Type: T1 form factor
• Lead Configuration: 2-lead (2LD)
• Material: Black PVC
• Mounting Orientation: Vertical
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1

Allowable Variation Parameter:

• Standoff Height: Dimensional tolerance within mechanical design constraints

The ELM 2-100 qualifies as a parametric equivalent because it maintains identical specifications across all mandatory parameters. The primary distinction is the standoff height: ELM 2-100 measures 0.100" (2.54mm) compared to the ELM 4-105 at 0.105" (2.67mm). This 0.005" (0.13mm) difference represents a 4.8% reduction in vertical clearance and must be evaluated within the specific application's mechanical layout requirements.

Engineering Selection Recommendations

Primary Part Selection (ELM 4-105): Select the ELM 4-105 when the application design specifies a 0.105" (2.67mm) standoff height and inventory availability permits standard lead times. This part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity tolerance, supporting long-term production continuity.

Substitute Part Selection (ELM 2-100): The ELM 2-100 serves as a functional substitute when the ELM 4-105 experiences supply constraints. This substitution is valid only when the mechanical design accommodates a 0.005" (0.13mm) reduction in standoff height. Both parts share identical compliance certifications (ROHS3, MSL 1), identical electrical interfaces (2-lead T1 configuration), and identical material composition (black PVC). The ELM 2-100 maintains Active product status and is suitable for production applications.

Substitution Constraints: Substitution is not permissible if the application design requires the specific 0.105" height dimension or if the reduced clearance of 0.100" creates mechanical interference with adjacent components or PCB features.

Frequently Asked Questions (FAQ)

Q: Can the ELM 2-100 be used as a direct replacement for the ELM 4-105 in all applications?

A: The ELM 2-100 is a parametric equivalent with respect to electrical and material specifications. However, the 0.005" height difference must be evaluated against the specific mechanical design. Direct replacement is permissible only when the application layout accommodates the reduced standoff height without creating component interference or violating design clearance requirements.

Q: What is the significance of the standoff height difference between these parts?

A: The ELM 4-105 provides 0.105" (2.67mm) of vertical clearance, while the ELM 2-100 provides 0.100" (2.54mm). This 4.8% reduction affects the vertical spacing between the LED and the PCB surface. Applications with tight vertical constraints or specific LED positioning requirements must account for this dimensional variance.

Q: Are both parts equally suitable for long-term production use?

A: Both the ELM 4-105 and ELM 2-100 maintain Active product status and ROHS3 compliance. Both carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special storage or handling requirements. From a compliance and availability perspective, both parts are suitable for production applications.

Q: What packaging format is used for these parts?

A: Both the ELM 4-105 and ELM 2-100 are supplied in Bag packaging, consistent with standard component distribution for LED standoff assemblies.

Q: Are there any electrical performance differences between these substitute parts?

A: No electrical performance differences exist. Both parts feature identical 2-lead (2LD) configurations, T1 LED form factors, and black PVC construction. Electrical characteristics are determined by the LED component itself, not the standoff assembly.

Q: What is the inventory status for these parts?

A: The ELM 4-105 maintains 659 pieces in stock. The ELM 2-100 maintains significantly higher inventory at 32,038 pieces. Inventory levels may influence substitution decisions when supply constraints affect the primary part.
