ELM 2-450 Equivalent & Substitute Parts

Part Overview

The ELM 2-450 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.450" (11.43mm) length. This component is designed for vertical mounting applications requiring LED positioning and spacing. 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 is required due to inventory constraints, design revisions, or application-specific dimensional adjustments within acceptable tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

The ELM 4-440 is identified as a parametric equivalent to the ELM 2-450 based on the following shared electrical and mechanical parameters:

• LED Type: Both parts utilize T1 LED configuration
• Material Composition: Both feature black PVC construction
• Mounting Orientation: Both are designed for vertical mounting applications
• Color: Both are black
• RoHS Compliance: Both meet ROHS3 requirements
• Moisture Sensitivity Level: Both carry MSL 1 rating
• Manufacturer: Both are manufactured by Bivar Inc.
• Product Status: Both maintain Active status

The primary dimensional difference is length: ELM 2-450 measures 0.450" (11.43mm) while ELM 4-440 measures 0.440" (11.18mm), representing a 0.010" (0.25mm) variance. This substitution is valid where application design tolerances accommodate this dimensional difference.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 2-450 and ELM 4-440 are Active products manufactured by Bivar Inc. with identical RoHS3 compliance and MSL 1 ratings. Selection between these parts is determined by application-specific length requirements. The ELM 2-450 is specified for designs requiring 0.450" (11.43mm) standoff height, while the ELM 4-440 accommodates designs with 0.440" (11.18mm) height specifications. Both parts are suitable for production use and carry equivalent regulatory compliance certifications. Component selection should be based on PCB layout requirements and mechanical clearance specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-440 be used as a direct replacement for ELM 2-450?

A: The ELM 4-440 is a parametric equivalent with identical electrical and material specifications. However, the 0.010" (0.25mm) length difference must be evaluated against application mechanical tolerances. Direct substitution is valid only when design specifications accommodate the shorter standoff height.

Q: What are the critical parameters for substitution between these parts?

A: Substitution is valid based on matching LED type (T1), material (black PVC), mounting style (vertical), color (black), RoHS compliance (ROHS3), and MSL rating (1). The length differential is the only distinguishing parameter and must be verified against application requirements.

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

A: Yes, both ELM 2-450 and ELM 4-440 are supplied in Bag packaging, ensuring consistent handling and storage procedures across both part numbers.

Q: Do these parts carry the same regulatory certifications?

A: Both parts are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both are manufactured by Bivar Inc. and maintain Active product status, ensuring equivalent regulatory and compliance standing.

Q: What is the dimensional tolerance consideration for substitution?

A: The length difference of 0.010" (0.25mm) between the ELM 2-450 and ELM 4-440 represents the primary substitution variable. Application design specifications must explicitly permit this dimensional variance for substitution to be valid.
