ELM 2-145 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 2-145 is a T1 LED standoff manufactured by Bivar Inc., constructed from black PVC material with a length of 0.145" (3.68mm). This component is classified as an active product with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts become necessary when the ELM 2 series experiences supply constraints, inventory limitations, or when design flexibility permits selection from equivalent standoff configurations within compatible mechanical and electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the ELM 2-145 is determined by compatibility across the following parameters: LED type (T1), material composition (PVC), color (black), RoHS compliance status, and MSL rating. Two substitution categories exist:

Category 1: Exact Parametric Match (Same Series Length) The ELM 4-145 shares identical length (0.145"), LED type, material, and color specifications. This represents a direct substitution within the same dimensional envelope.

Category 2: Parametric Equivalents (Extended Length) The ELM 4-150 and ELM 5-150 provide substitution with a length variation of 0.005" (0.13mm increase to 0.150"). Both maintain T1 LED type, black PVC material, and equivalent compliance certifications. Length variation permits substitution in applications where the additional 0.005" standoff height is mechanically acceptable.

All three substitute parts originate from Bivar Inc., ensuring manufacturing consistency and quality standards equivalent to the primary part.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, ensuring equivalence for regulated applications. The ELM 4-145 is the preferred substitute when supply of the ELM 2-145 is unavailable, providing identical dimensional and material specifications. The ELM 4-150 and ELM 5-150 are suitable when a 0.005" length increase is mechanically acceptable within the assembly design. Selection should prioritize active status parts, with inventory availability as a secondary consideration. All parts meet the same regulatory and environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-145 replace ELM 2-145 in all applications? A: Yes. The ELM 4-145 provides identical parametric specifications including LED type, length, material, color, and compliance ratings.

Q: What is the difference between the ELM 4-150 and ELM 5-150? A: Both parts share identical length, LED type, material, and color specifications. The distinction resides in series designation (ELM 4 versus ELM 5). Both are functionally equivalent for substitution purposes.

Q: Can I use a 0.150" standoff where a 0.145" part is specified? A: Substitution with ELM 4-150 or ELM 5-150 requires mechanical verification that the 0.005" (0.13mm) additional height does not conflict with assembly constraints or design clearances.

Q: Are all substitute parts RoHS3 compliant? A: Yes. The ELM 4-145, ELM 4-150, and ELM 5-150 all meet ROHS3 compliance requirements.

Q: What is the packaging format for these parts? A: All parts are supplied in bag packaging.

Q: Is inventory status a substitution constraint? A: No. Inventory levels fluctuate and do not affect parametric compatibility. Substitute parts are selected based on compliance with dimensional, material, and electrical specifications.
