ELM 5-900 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 5-900 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.900" (22.86mm) length specification. This component is constructed from black PVC material and accommodates standard T1 LEDs with a 3mm base configuration. The part maintains active product status and is ROHS3 compliant, supporting long-term deployment in electronic assemblies. Alternative part numbers become necessary when specific length requirements vary slightly within acceptable mechanical tolerances or when supply chain optimization requires sourcing from available inventory levels.

Key Parameters

Substitute Part Grouping Explanation

The ELM 5-23MM qualifies as a parametric equivalent within the ELM 5 series based on the following critical parameters:

Defining Substitution Criteria:

• Same manufacturer (Bivar Inc.)
• Identical series classification (ELM 5)
• Compatible LED type (T1)
• Identical material composition (PVC, Black)
• Matching mounting configuration (vertical, 3mm base)
• Equivalent compliance certifications (ROHS3, MSL 1)

Length Variance: The substitute part specifies 0.910" (23.11mm) compared to the main part's 0.900" (22.86mm), representing a 0.010" (0.25mm) difference. This variation falls within standard mechanical tolerance ranges for LED standoff assemblies and does not affect functional compatibility in applications where the standoff serves as a spacer or positioning element.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 5-900 and ELM 5-23MM maintain active product status with equivalent regulatory compliance. The ELM 5-23MM provides an additional 0.010" (0.25mm) extension in standoff length. Selection between these parts depends on specific mechanical clearance requirements within the application. The ELM 5-23MM currently maintains significantly higher inventory availability (7087 pcs versus 797 pcs), making it advantageous for high-volume production or supply chain continuity. Both parts carry identical ROHS3 compliance and unlimited moisture sensitivity ratings, ensuring equivalent performance in environmental conditions.

Frequently Asked Questions (FAQ)

Q: What are the primary differences between ELM 5-900 and ELM 5-23MM? A: The parts differ only in length specification: ELM 5-900 measures 0.900" (22.86mm) while ELM 5-23MM measures 0.910" (23.11mm). All other parameters including material, LED type, color, and compliance certifications remain identical.

Q: Can ELM 5-23MM be used as a direct replacement for ELM 5-900? A: Yes, ELM 5-23MM is functionally compatible as a substitute. The 0.010" length difference represents a standard tolerance variation within LED standoff specifications and does not compromise mechanical compatibility in vertical mounting applications.

Q: Are both parts RoHS compliant? A: Both ELM 5-900 and ELM 5-23MM are ROHS3 compliant with unlimited moisture sensitivity ratings (MSL 1), suitable for long-term storage and deployment without environmental restrictions.

Q: Which part should be selected for new designs? A: Both parts are active products. Selection should be based on the specific mechanical clearance requirements of your assembly. If clearance is not a constraint, the ELM 5-23MM may be preferred due to higher inventory availability.

Q: Are there any supply considerations between these parts? A: The ELM 5-23MM currently has significantly higher inventory availability, which may influence supply chain planning for volume production runs or long-term component sourcing.
