ELM 4-635 Equivalent & Substitute Parts

Part Overview

The ELM 4-635 is a T1 LED standoff manufactured by Bivar Inc., constructed from black PVC material with a height of 0.635" (16.13mm). This component is designed to provide mechanical spacing and alignment for T1 LED assemblies in vertical mounting configurations. The product maintains Active status and full ROHS3 compliance. Equivalent part identification becomes necessary when stock availability constraints or supply chain optimization require sourcing alternative models that maintain functional compatibility within the same product family.

Key Parameters

Substitute Part Grouping Explanation

The ELM 2-665 is identified as a parametric equivalent to the ELM 4-635 based on the following critical substitution criteria:

Maintained Parameters (Substitution Basis):

• LED Type: T1 (identical)
• Material: Black PVC (identical)
• Mounting Configuration: Vertical (identical)
• Packaging: Bag (identical)
• RoHS Compliance: ROHS3 (identical)
• Moisture Sensitivity Level: 1 – Unlimited (identical)
• Manufacturer: Bivar Inc. (identical)

Variable Parameter:

• Length: ELM 4-635 at 0.635" (16.13mm) versus ELM 2-665 at 0.665" (16.89mm)

The ELM 2-665 maintains all electrical, material, and compliance characteristics while introducing a 0.030" (0.76mm) length variation. This dimensional difference permits substitution only in applications where the increased standoff height does not create mechanical constraint violations or alter final assembly geometry.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 4-635 and ELM 2-665 maintain Active product status, indicating ongoing manufacturer support and availability. Both components carry identical ROHS3 compliance certification and MSL Level 1 rating, confirming equivalent regulatory and environmental suitability for industrial applications.

Selection between these parts depends solely on mechanical clearance requirements within the target assembly. The ELM 4-635 is appropriate for applications requiring the precise 0.635" standoff height. The ELM 2-665 provides an alternative when the 0.665" dimension accommodates the mechanical design without constraint. No functional, electrical, or compliance compromises exist between the two options within their respective dimensional parameters.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-665 replace ELM 4-635 in any application?

A: Substitution validity depends exclusively on mechanical space availability. The ELM 2-665 introduces 0.030" additional height. Confirm that the assembly envelope accommodates this dimension before implementation.

Q: Are the standoff materials identical?

A: Yes. Both components use black PVC material with identical LED type (T1) and vertical mounting configuration.

Q: Do both parts have identical compliance certifications?

A: Both parts carry ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) ratings. Regulatory compatibility is maintained between the two options.

Q: What is the significance of the different series designations (ELM 4 vs. ELM 2)?

A: Series designations reflect internal manufacturer categorization related to physical dimensions. The ELM 2 and ELM 4 series share identical material, LED type, and compliance characteristics while differing in standoff height.

Q: Are there packaging or inventory considerations affecting substitution?

A: Both parts are packaged in bags. Verify current inventory availability through your supplier. The ELM 4-635 currently maintains 968 pieces in stock, while ELM 2-665 maintains 882 pieces.
