ELM 4-17MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-17MM is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.670" (17.02mm) length. This component is constructed from black PVC material and accommodates T1 LED packages with a 3mm configuration and 2-lead design. The part maintains Active product status and is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Substitute parts become necessary when primary inventory is unavailable, when design flexibility permits dimensional tolerance, or when alternative series options meet functional requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the ELM 4-17MM is based on the following critical parameters that must remain constant across all equivalent parts:

Mandatory Matching Parameters:

• LED Type: T1 (physical package compatibility)
• Material: Black PVC (mechanical and environmental properties)
• Configuration: 3MM 2LD vertical mount (PCB interface)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• MSL Rating: 1 (Unlimited) (moisture protection level)
• Product Status: Active (manufacturing availability)

Allowable Variation Parameters:

• Length: Within 0.665" to 0.670" range (±0.005" tolerance acceptable for mounting height)
• Series designation: ELM 2 or ELM 4 series (both manufactured by Bivar Inc.)

The two identified substitutes—ELM 2-17MM and ELM 2-665—maintain all mandatory parameters while representing different series options and minor dimensional variations within acceptable engineering tolerances.

Engineering Selection Recommendations

ELM 2-17MM Selection Criteria: This substitute provides exact dimensional matching to the ELM 4-17MM with identical 0.670" (17.02mm) length. Both parts maintain Active product status and full ROHS3 compliance. The ELM 2-17MM represents an alternative series designation within the Bivar Inc. product line while preserving all critical electrical and mechanical parameters. Current inventory of 1815 units supports immediate availability.

ELM 2-665 Selection Criteria: This substitute introduces a minor dimensional variation with 0.665" (16.89mm) length, representing a 0.005" (0.13mm) reduction from the primary part. This dimensional tolerance remains within standard engineering practices for LED standoff applications. The ELM 2-665 maintains all mandatory compliance certifications and Active product status. Selection of this part is appropriate when the reduced mounting height accommodates design requirements and inventory availability is prioritized (882 units in stock).

Compliance Basis: All three parts maintain identical RoHS3 compliance status and MSL 1 (Unlimited) moisture sensitivity ratings, confirming suitability for equivalent environmental and regulatory applications. Active product status across all options ensures continued manufacturing support and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-17MM be used as a direct replacement for ELM 4-17MM?

A: Yes. The ELM 2-17MM maintains identical length (0.670"), LED type (T1), material (Black PVC), configuration (3MM 2LD vertical mount), and all compliance certifications (ROHS3, MSL 1). The series designation change from ELM 4 to ELM 2 does not affect functional compatibility.

Q: What is the significance of the 0.005" length difference between ELM 4-17MM and ELM 2-665?

A: The ELM 2-665 measures 0.665" (16.89mm) compared to 0.670" (17.02mm) for the primary part. This 0.005" (0.13mm) reduction represents a minor dimensional variation. Substitution is appropriate when PCB layout and component clearance accommodate the reduced mounting height.

Q: Are all three parts packaged identically?

A: Yes. ELM 4-17MM, ELM 2-17MM, and ELM 2-665 are all supplied in Bag packaging, ensuring consistent handling and storage requirements.

Q: Do the substitute parts maintain the same moisture sensitivity protection?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity level classification and environmental protection capabilities.

Q: What inventory levels support each part option?

A: ELM 4-17MM: 774 units; ELM 2-17MM: 1815 units; ELM 2-665: 882 units. All quantities represent new original stock.

Q: Are there any regulatory or compliance differences between the substitute parts?

A: No. All three parts maintain ROHS3 compliance status and identical ECCN (EAR99) and HTSUS classifications, confirming equivalent regulatory treatment.

Q: Can ELM 2-665 be used in applications requiring exact 0.670" mounting height?

A: No. The ELM 2-665 length of 0.665" introduces a 0.005" dimensional difference. Use this substitute only when design specifications permit the reduced mounting height.
