ELM 4-640

Part Overview

The ELM 4-640 is a T1 LED standoff manufactured by Bivar Inc., constructed from black PVC material with a height of 0.640" (16.26mm). This component is actively produced and classified as ROHS3 compliant. Alternative models are available to accommodate varying PCB heights and mechanical specifications while maintaining functional compatibility with T1 LED applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 4-640 are grouped based on the following key parameters:

• LED Type: All substitutes support T1 LED components
• Material: All substitutes are black PVC construction
• RoHS Compliance: All substitutes maintain ROHS3 compliance
• Moisture Sensitivity Level: All substitutes maintain MSL 1 rating
• Length Variance: Substitute parts vary in height (0.665" and 0.670") to accommodate different PCB mounting requirements

The ELM 2-665 and ELM 2-17MM are functionally equivalent alternatives that differ primarily in mechanical height specification, allowing selection based on specific PCB design constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts (ELM 4-640, ELM 2-665, and ELM 2-17MM) are active products manufactured by Bivar Inc. with identical RoHS3 compliance and MSL 1 ratings. Selection between these alternatives should be determined by mechanical height requirements specific to the PCB design. The ELM 4-640 is recommended for applications requiring 0.640" standoff height; ELM 2-665 for 0.665" height applications; and ELM 2-17MM for 0.670" height applications. All parts meet equivalent regulatory and environmental compliance standards.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-665 and ELM 2-17MM be used interchangeably with ELM 4-640? A: These parts are parametric equivalents with identical LED type, material, color, and compliance ratings. Interchangeability depends on PCB design tolerance for the specified height differences (0.640" vs. 0.665" vs. 0.670"). Mechanical clearance and electrical connection points must be verified for the selected height specification.

Q: What is the primary difference between the substitute parts? A: The ELM 2-665 and ELM 2-17MM differ in length specification. ELM 2-665 provides 0.665" height, while ELM 2-17MM provides 0.670" height. Both maintain identical material composition, LED type, and compliance characteristics.

Q: Are these parts RoHS compliant? A: All parts (ELM 4-640, ELM 2-665, and ELM 2-17MM) are ROHS3 compliant and meet environmental regulatory requirements for electronic components.

Q: What does MSL 1 mean for these components? A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life with no moisture sensitivity restrictions. These parts do not require special moisture control handling or storage conditions.

Q: What is the package format? A: All parts are supplied in bag packaging, suitable for bulk component procurement and assembly operations.
