ELM 2-405 Equivalent & Substitute Parts

Part Overview

The ELM 2-405 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.405" (10.29mm) length and accommodates T1 LED packages with 2-lead configuration. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity tolerance. Substitute parts are identified when equivalent functional performance can be achieved through alternative Bivar Inc. series offerings that maintain compatibility with the same LED package type, material composition, and electrical specifications while accommodating minor dimensional variations within acceptable mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 2-405 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED package type (T1)
• Lead configuration (2-lead)
• Material composition (Black PVC)
• Mounting orientation (Vertical)
• Manufacturer (Bivar Inc.)
• RoHS compliance status (ROHS3)
• Moisture sensitivity level (MSL 1)

Allowable Variation:

• Length tolerance within mechanical design constraints

The ELM 5-390 qualifies as a parametric equivalent because it maintains identical specifications across all primary compatibility criteria. The dimensional difference of 0.015" (0.38mm) in length represents a minor mechanical variation that does not affect functional performance in applications where the T1 LED standoff serves as a vertical mounting interface.

Engineering Selection Recommendations

ELM 2-405 Primary Selection: The ELM 2-405 is recommended for applications requiring the specified 0.405" (10.29mm) standoff length. Active product status ensures ongoing availability and manufacturing support. RoHS3 compliance and MSL 1 rating satisfy regulatory requirements for commercial and industrial applications without moisture-related constraints.

ELM 5-390 Substitute Selection: The ELM 5-390 serves as a functional equivalent where the 0.390" (9.91mm) length accommodates design specifications. This substitute maintains identical electrical and material properties, RoHS3 compliance, and MSL 1 rating. Selection between ELM 2-405 and ELM 5-390 is determined solely by mechanical length requirements within the application's PCB layout and component spacing constraints.

Both parts are Active status products manufactured by Bivar Inc., ensuring equivalent quality and compliance standards.

Frequently Asked Questions (FAQ)

Q: What determines whether ELM 5-390 can replace ELM 2-405?

A: Substitution is valid when the application's mechanical design accommodates the 0.015" (0.38mm) shorter length of the ELM 5-390. Both parts are identical in LED type (T1), lead configuration (2LD), material (Black PVC), mounting orientation (Vertical), and compliance specifications (RoHS3, MSL 1). Length is the only variable parameter.

Q: Are there electrical differences between these parts?

A: No. Both ELM 2-405 and ELM 5-390 are mechanical standoffs for T1 LED packages. They contain no active electrical components and do not introduce electrical differences into circuit designs.

Q: Can these parts be used interchangeably in all applications?

A: Interchangeability is limited to applications where the mechanical length difference does not conflict with PCB layout, component clearance, or assembly requirements. The 0.015" (0.38mm) variation must be evaluated against specific design constraints.

Q: What is the significance of the series designation (ELM 2 vs. ELM 5)?

A: Series designation indicates different product lines within Bivar Inc.'s LED standoff portfolio. Both series maintain identical specifications for T1 LED packages, material composition, and compliance ratings. Series differences reflect manufacturing or design lineage but do not affect functional compatibility.

Q: Are both parts available in the same packaging format?

A: Yes. Both ELM 2-405 and ELM 5-390 are supplied in Bag packaging, ensuring consistent handling and storage requirements.

Q: What does MSL 1 (Unlimited) mean for these components?

A: MSL 1 indicates these components have no moisture sensitivity limitations. They do not require special moisture-controlled storage, handling, or baking procedures prior to assembly or use.

Q: Are both parts RoHS3 compliant?

A: Yes. Both ELM 2-405 and ELM 5-390 are RoHS3 compliant, meeting regulatory requirements for hazardous substance restrictions in electrical and electronic equipment.
