ELM 2-940 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 2-940 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.940" (23.90mm) length. This component is constructed from black PVC material and accommodates 3MM LED configurations with 2-lead connections. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments.

Substitute parts are identified when equivalent electrical and mechanical parameters align within the allowed tolerance specifications for this product category, enabling direct functional replacement in applications where the primary part is unavailable or inventory constraints exist.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 2-940 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• LED Type: T1
• Material: PVC
• Color: Black
• Lead Configuration: 2LD
• Mounting Orientation: Vertical
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Length tolerance: Mechanical standoff length may vary within the range of 0.910" to 0.940" (23.11mm to 23.90mm) for 3MM LED accommodation, as both dimensions support equivalent vertical mounting applications.

The ELM 5-23MM meets all mandatory matching parameters and falls within the allowable length variation, qualifying as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 2-940 and ELM 5-23MM are Active products manufactured by Bivar Inc. with identical ROHS3 compliance and MSL ratings. Selection between these parts should be based on:

1. Inventory Availability: ELM 5-23MM maintains higher inventory levels (7087 Pcs) compared to ELM 2-940 (793 Pcs), supporting supply chain continuity.

2. Mechanical Fit: The 0.030" (0.79mm) length difference between parts falls within standard mechanical tolerances for vertical LED standoff applications. Both lengths accommodate 3MM LED configurations identically.

3. Compliance Equivalence: Both parts carry identical RoHS3 certification and unlimited moisture sensitivity ratings, ensuring equivalent performance in regulated manufacturing environments.

4. Series Designation: ELM 2-940 belongs to the ELM 2 series while ELM 5-23MM belongs to the ELM 5 series. Both series utilize identical material composition, color specification, and electrical lead configuration.

Frequently Asked Questions (FAQ)

Q: Can ELM 5-23MM directly replace ELM 2-940 in production assemblies?

A: Yes. Both parts meet identical specifications for LED type (T1), material (PVC), color (Black), lead configuration (2LD), and compliance requirements (ROHS3). The 0.030" length difference is within standard mechanical tolerance for vertical standoff applications.

Q: What is the significance of the length difference between 0.940" and 0.910"?

A: Both lengths are designed to support 3MM LED vertical mounting. The 0.030" variation represents a 0.3% dimensional difference and does not affect electrical performance or mechanical compatibility in standard PCB assembly applications.

Q: Are both parts suitable for RoHS3 regulated applications?

A: Yes. Both ELM 2-940 and ELM 5-23MM carry ROHS3 Compliant certification and are rated MSL 1 (Unlimited), qualifying them for use in regulated manufacturing environments without additional moisture or thermal management requirements.

Q: What packaging format is used for both parts?

A: Both parts are supplied in Bag packaging, maintaining identical handling and storage requirements.

Q: Why are there two different series designations (ELM 2 vs. ELM 5) for functionally equivalent parts?

A: Series designation reflects internal Bivar Inc. product line organization. Functional equivalence is determined by matching electrical and mechanical parameters, not series number. Both series utilize identical material, color, LED accommodation, and compliance specifications.
