ELM 2-140 LED Standoff

Part Overview

The ELM 2-140 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications requiring a 0.140" (3.56mm) height specification. This component is a black PVC standoff engineered to support LED assemblies in precision positioning applications. The product is currently Active in production status with full ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring reliable performance across standard manufacturing and operational environments. Equivalent substitute parts are available to accommodate minor dimensional variations and alternative inventory availability while maintaining core functional and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The ELM 4-145 serves as a parametric equivalent to the ELM 2-140 within the Bivar Inc. LED standoff family. Substitution compatibility is determined by the following key parameters:

• LED Type Compatibility: Both parts support T1 LED configurations, maintaining identical LED interface specifications.
• Material Specification: Both utilize black PVC construction, ensuring equivalent mechanical and environmental performance characteristics.
• Compliance Requirements: Both parts maintain ROHS3 compliance and MSL 1 rating, meeting identical regulatory and moisture sensitivity standards.
• Dimensional Tolerance: The length variance between 0.140" (3.56mm) and 0.145" (3.68mm) represents a 0.005" (0.12mm) difference, which falls within acceptable mechanical tolerance for standoff applications where height represents a non-critical dimension in standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Both ELM 2-140 and ELM 4-145 are active production components with equivalent regulatory standing and environmental ratings. Selection between these parts is based on dimensional requirements and inventory availability. The ELM 2-140 is specified for applications requiring 0.140" height, while the ELM 4-145 accommodates 0.145" height specifications. Both parts carry full ROHS3 compliance certification and MSL 1 unlimited rating, confirming compatibility with standard manufacturing processes and operational environments. Part selection should be driven by specific mechanical height requirements in the assembly design.

Frequently Asked Questions (FAQ)

Can ELM 4-145 replace ELM 2-140 in existing designs?

Substitution is permissible only when the 0.005" (0.12mm) height difference does not violate design specifications. Review mechanical clearance requirements and component positioning constraints before implementation.

Are compliance and environmental ratings identical between the two parts?

Yes. Both parts maintain ROHS3 compliance and MSL 1 unlimited rating, confirming equivalent environmental performance and regulatory standing.

What is the primary difference between these two standoff models?

The ELM 4-145 has a 0.145" (3.68mm) length specification compared to the 0.140" (3.56mm) of the ELM 2-140. Both parts share identical material composition, LED type support, and compliance certifications.

How does the dimensional difference affect PCB assembly compatibility?

The 0.005" height variance typically has minimal impact on standard PCB assembly operations. Verify that the increased height does not create clearance conflicts with adjacent components or assembly fixtures.

Are both parts available in equivalent quantities?

Inventory availability varies. ELM 2-140 has 834 units in stock, while ELM 4-145 has 6,639 units available. Consult current inventory status for procurement planning.
