ELM 3-805 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-805 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.805" (20.45mm) length. This component is constructed from black PVC material and is classified as an active product with full RoHS3 compliance. LED standoffs serve as mechanical and electrical positioning elements in circuit assemblies, and equivalent or substitute parts may be required due to inventory availability, supply chain considerations, or specific application requirements within allowable parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 3-805 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 3/4 (mechanical and electrical interface standard)
• Material: Black PVC (chemical and thermal compatibility)
• Mounting Style: Vertical (assembly orientation)
• Color: Black (visual and material specification)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (storage and handling compatibility)

Allowable Variation:

• Length tolerance: Parts within the ELM series with T1 3/4 LED compatibility and identical material/color specifications are classified as parametric equivalents. The ELM 1-820 exhibits a length of 0.820" (20.83mm), representing a 0.015" (0.38mm) dimensional variance from the main part.

The ELM 1-820 qualifies as a parametric equivalent based on matching LED type, material, color, mounting style, and compliance certifications, with length variation within acceptable mechanical tolerance ranges for standoff applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 3-805 and ELM 1-820 are active products manufactured by Bivar Inc. with identical RoHS3 compliance and MSL ratings. Selection between these parts should be based on:

1. Dimensional Requirements: The 0.015" (0.38mm) length difference between parts must be evaluated against circuit board layout and assembly clearance specifications.

2. Inventory Availability: The ELM 1-820 maintains higher inventory levels (1983 pcs) compared to the ELM 3-805 (715 pcs), which may influence supply chain decisions.

3. Regulatory Compliance: Both parts satisfy ROHS3 requirements and carry identical MSL ratings, ensuring equivalent environmental and handling compliance.

4. Material and Mechanical Compatibility: Identical PVC material composition and T1 3/4 LED interface ensure mechanical and thermal compatibility in vertical mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the ELM 1-820 be used as a direct replacement for the ELM 3-805?

A: The ELM 1-820 is a parametric equivalent with matching LED type, material, color, and compliance specifications. The 0.015" length difference must be evaluated against specific circuit board design requirements and assembly clearances before substitution.

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

A: The ELM 3-805 measures 0.805" (20.45mm) while the ELM 1-820 measures 0.820" (20.83mm). This 0.015" (0.38mm) variance affects the vertical standoff height and must be considered in PCB layout and component clearance calculations.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ELM 3-805 and ELM 1-820 carry ROHS3 Compliant certification and are suitable for applications requiring RoHS compliance.

Q: What is the Moisture Sensitivity Level for these parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Do these parts use the same packaging?

A: Yes. Both the ELM 3-805 and ELM 1-820 are supplied in bag packaging.

Q: What LED type do these standoffs accommodate?

A: Both parts are designed for T1 3/4 LED components, ensuring mechanical and electrical interface compatibility with standard T1 3/4 LED packages.
