ELM 2-420 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 2-420 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.420" (10.67mm) vertical mounting height. This component is designed for applications requiring precision LED positioning and alignment in electronic assemblies. The part maintains Active product status and is RoHS3 compliant, making it suitable for current production environments. Substitute parts may be required due to inventory constraints, design modifications requiring different standoff heights, or application-specific mechanical clearance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELM 2-420 is limited to parts that maintain compatibility across the following critical parameters:

Substitution-Determining Parameters:

• LED Type: T1 (fixed requirement)
• Material: Black PVC (fixed requirement)
• Manufacturer: Bivar Inc. (fixed requirement)
• RoHS Status: ROHS3 Compliant (fixed requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (fixed requirement)

Variable Parameter Allowing Substitution:

• Length (Height): Mechanical dimension that may vary based on application requirements

The ELM 4-440 qualifies as a parametric equivalent because it maintains identical specifications across all fixed parameters while offering a different standoff height of 0.440" (11.18mm) versus the original 0.420" (10.67mm). This 0.020" (0.51mm) height difference accommodates applications requiring increased vertical clearance or different LED positioning geometry.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 2-420 and ELM 4-440 maintain Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is determined by mechanical clearance requirements within the assembly. The ELM 2-420 provides a 0.420" standoff height, while the ELM 4-440 provides 0.440" height. Choose the ELM 4-440 when additional vertical clearance is required for component placement or when PCB layout modifications necessitate increased LED positioning height. Both parts are suitable for production use with equivalent environmental and regulatory compliance profiles.

Frequently Asked Questions (FAQ)

Q: Can the ELM 4-440 be used as a direct replacement for the ELM 2-420?

A: The ELM 4-440 is a parametric equivalent with identical electrical and material specifications. However, the 0.020" (0.51mm) height difference must be evaluated against your specific PCB layout and mechanical clearance requirements. Direct substitution is only appropriate if this height variation does not conflict with component placement or assembly constraints.

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

A: The ELM 2-420 provides 0.420" (10.67mm) vertical standoff height, while the ELM 4-440 provides 0.440" (11.18mm). This 0.020" difference affects LED positioning relative to the PCB surface and may impact clearance with adjacent components or enclosure geometry.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ELM 2-420 and ELM 4-440 are RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), making them suitable for equivalent environmental and regulatory requirements.

Q: What packaging format is used for both parts?

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

Q: Can I use these parts interchangeably in existing designs?

A: Interchangeability depends on mechanical tolerance and clearance specifications in your design. The height difference must be verified against PCB layout, component spacing, and enclosure constraints before substitution.
