ELM 2-900 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 2-900 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a height of 0.900" (22.86mm). This component is an active product manufactured from black PVC material and is ROHS3 compliant. Finding equivalent and substitute parts is necessary when the primary part is unavailable or when design flexibility permits the use of alternative standoff heights within acceptable mechanical tolerances for LED positioning in vertical mount configurations.

Substitute Part Grouping Explanation

Substitution of the ELM 2-900 is limited to parts that maintain identical core parameters: T1 LED type, black PVC material, vertical mounting orientation, and ROHS3 compliance. The primary allowable variable is the standoff length, which may vary within mechanical tolerance margins for PCB-to-LED spacing applications. The ELM 5-23MM qualifies as a parametric equivalent because it matches all critical parameters except for a minor length variation of 0.010" (0.25mm), from 0.900" to 0.910". This difference is within standard mechanical tolerances for most vertical LED mounting applications and does not affect the electrical or functional characteristics of the assembly.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 2-900 and ELM 5-23MM are active products with ROHS3 compliance and identical moisture sensitivity ratings. The ELM 5-23MM presents a valid alternative when the ELM 2-900 is unavailable, provided that the 0.010" (0.25mm) increase in standoff height is compatible with the mechanical design of the application. Both parts are manufactured by the same supplier using identical material composition and meet the same regulatory requirements, ensuring consistent performance in vertical LED mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the ELM 5-23MM be used as a direct replacement for the ELM 2-900? A: The ELM 5-23MM is a parametric equivalent with an increase in length of 0.010" (0.25mm). It is suitable as a replacement when this height difference is acceptable within the mechanical tolerance of the application design.

Q: Are there any electrical differences between the ELM 2-900 and ELM 5-23MM? A: No. Both parts are T1 LED standoffs with identical electrical characteristics. The only difference is the physical standoff height.

Q: What is the significance of the length variation? A: The length variation of 0.010" (0.25mm) affects the vertical spacing between the PCB and the LED tip. The designer must confirm that this height difference does not impact circuit layout, mechanical clearances, or optical performance in the target application.

Q: Are both parts RoHS compliant? A: Yes. Both the ELM 2-900 and ELM 5-23MM are ROHS3 compliant and suitable for applications with RoHS regulatory requirements.

Q: Do both parts have the same moisture sensitivity rating? A: Yes. Both parts have an MSL rating of 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.
