ELM 2-640 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 2-640 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.640" (16.26mm) length. This component is an active product with full RoHS3 compliance and MSL Level 1 rating, indicating unlimited moisture sensitivity tolerance. Substitute parts are identified based on matching electrical and mechanical parameters within the ELM 2 series, enabling direct replacement in applications where dimensional and functional compatibility is maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the ELM 2 series is determined by the following criteria:

Primary Compatibility Parameters:

• Manufacturer: Bivar Inc. (same manufacturer ensures design consistency)
• Series: ELM 2 (same product family)
• LED Type: T1 (identical LED form factor)
• Material: PVC (identical material composition)
• Color: Black (identical color specification)
• Mounting Style: Vertical (identical orientation)
• RoHS Status: ROHS3 Compliant (equivalent environmental compliance)
• MSL Rating: 1 (Unlimited) (equivalent moisture tolerance)

Secondary Consideration:

• Length: Variations within the ELM 2 series accommodate different PCB standoff heights. The ELM 2-640 (0.640"), ELM 2-665 (0.665"), and ELM 2-17MM (0.670") represent length variants suitable for applications requiring different vertical spacing.

All substitute parts maintain identical electrical and mechanical interfaces, differing only in overall length to accommodate specific PCB mounting requirements.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-640 Primary Selection: Select the ELM 2-640 when PCB design specifies a 0.640" (16.26mm) standoff height. This part maintains active product status with full RoHS3 compliance and unlimited moisture tolerance, suitable for standard industrial and commercial applications.

ELM 2-665 Substitute Selection: The ELM 2-665 provides a 0.025" (0.63mm) height increase over the ELM 2-640. Select this variant when PCB layout requires slightly increased vertical clearance while maintaining identical electrical and mechanical interfaces. RoHS3 compliance and MSL Level 1 rating are equivalent.

ELM 2-17MM Substitute Selection: The ELM 2-17MM provides a 0.030" (0.76mm) height increase over the ELM 2-640. Select this variant for applications requiring maximum vertical spacing within the ELM 2 series. All compliance certifications and material specifications remain identical.

All three parts are active products from Bivar Inc. with equivalent environmental compliance ratings. Selection is determined solely by PCB mounting height requirements.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-665 or ELM 2-17MM be used as direct replacements for ELM 2-640?

A: Direct replacement is possible only if PCB design accommodates the increased standoff height. ELM 2-665 adds 0.025" (0.63mm) and ELM 2-17MM adds 0.030" (0.76mm) to the vertical dimension. All three parts share identical electrical interfaces, material composition, and compliance certifications.

Q: What is the primary difference between these substitute parts?

A: The only difference is overall length. All parts are T1 LED standoffs manufactured from black PVC by Bivar Inc. within the ELM 2 series. Electrical performance, mounting style, and environmental compliance are identical.

Q: Are all three parts RoHS3 compliant?

A: Yes. ELM 2-640, ELM 2-665, and ELM 2-17MM all carry ROHS3 Compliant certification. MSL Level 1 (Unlimited) moisture sensitivity rating applies to all three variants.

Q: How do I determine which length variant is required for my application?

A: Length selection is determined by PCB design specifications for LED standoff height. Measure the required vertical distance from PCB surface to LED component top. Select the part number corresponding to your specified dimension: 0.640" (ELM 2-640), 0.665" (ELM 2-665), or 0.670" (ELM 2-17MM).

Q: Are these parts available in other colors or materials?

A: Based on provided specifications, ELM 2-640, ELM 2-665, and ELM 2-17MM are available only in black PVC. No alternative color or material variants are documented within this substitute group.

Q: What is the packaging format for these parts?

A: All three substitute parts are supplied in bag packaging, suitable for bulk component handling and automated assembly processes.
