ELM 4-340 Equivalent & Substitute Parts

Part Overview

The ELM 4-340 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.340" (8.64mm) length specification and accommodates T1 LED packages with a 2-lead configuration. The part maintains Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent functional performance can be achieved through alternative models within the same product family while maintaining critical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-340 is determined by the following critical parameters:

Mandatory Matching Parameters:

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

Allowable Variation:

• Length: Tolerance within mechanical design constraints of the application

The ELM 2-350 qualifies as a parametric equivalent because it maintains identical specifications across all mandatory parameters. The length differential of 0.010" (0.25mm) represents a minor mechanical variation within the T1 LED standoff product family.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 4-340 and ELM 2-350 maintain Active product status with full RoHS3 compliance and identical Moisture Sensitivity Level ratings. Selection between these parts is determined by the mechanical length requirement of the specific application. The ELM 4-340 provides a 0.340" standoff height, while the ELM 2-350 provides a 0.350" standoff height. All other electrical and mechanical characteristics remain equivalent. Component selection should be based on the PCB layout and vertical clearance specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can the ELM 2-350 be used in place of the ELM 4-340?

A: The ELM 2-350 is a parametric equivalent with identical LED type, material, lead count, mounting orientation, and compliance ratings. The 0.010" (0.25mm) length difference must be evaluated against the mechanical constraints of the specific application. If the application accommodates the increased standoff height, substitution is valid.

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

A: The ELM 4-340 provides 0.340" (8.64mm) of vertical standoff, while the ELM 2-350 provides 0.350" (8.89mm). This 0.010" difference affects the vertical clearance between the LED and the PCB surface. Applications with tight vertical space constraints may require the shorter ELM 4-340, while applications with additional clearance can accommodate the ELM 2-350.

Q: Are both parts RoHS compliant?

A: Yes. Both the ELM 4-340 and ELM 2-350 are RoHS3 compliant and carry identical Moisture Sensitivity Level ratings of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: What is the packaging format for these parts?

A: Both parts are supplied in Bag packaging format.

Q: Are there any electrical differences between these substitute parts?

A: No. Both parts are mechanical standoffs for T1 LED packages with identical electrical characteristics. They function as passive mechanical components with no active electrical properties.
