ELM 7-11MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 7-11MM is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.430" (10.92mm) length. This component is constructed from black PVC material and accommodates 3mm LED configurations with 2-lead connections. The part maintains Active product status and is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity tolerance.

Substitute parts are identified when inventory constraints, supply chain disruptions, or manufacturing discontinuation necessitate alternative component selection. Substitutes must maintain functional equivalence within the specified electrical and mechanical parameter ranges for this LED standoff category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 7-11MM is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• LED Type: T1 (physical form factor must remain identical)
• Material: Black PVC (chemical and mechanical properties must be equivalent)
• LED Configuration: 3mm, 2-lead (electrical and mounting interface must be compatible)
• Orientation: Vertical mounting (SR VERT designation)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Length: Tolerance range of ±0.010" (0.254mm) from nominal 0.430" (10.92mm) is permitted within standard mechanical tolerances for this product category

The substitute part ELM 4-440 qualifies as a parametric equivalent based on matching all critical parameters. The length differential of 0.010" (0.254mm) falls within acceptable mechanical tolerance for vertical LED standoff applications where PCB clearance and component height are non-critical design constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

Both ELM 7-11MM and ELM 4-440 maintain Active product status with ROHS3 compliance and MSL 1 rating. Selection between these parts should be based on the following engineering factors:

1. Mechanical Fit: The 0.010" (0.254mm) length difference between parts must be evaluated against PCB layout constraints and component clearance requirements. ELM 7-11MM provides the shorter standoff height at 0.430" (10.92mm), while ELM 4-440 provides 0.440" (11.18mm).

2. Regulatory Compliance: Both parts satisfy ROHS3 requirements and carry identical MSL 1 ratings, ensuring equivalent environmental performance and storage compatibility.

3. Inventory Availability: Selection may be determined by supply chain availability. Current inventory shows 982 units of ELM 7-11MM and 991 units of ELM 4-440 in stock.

4. Series Designation: ELM 7-11MM belongs to the ELM 7 series (base product ELM7-1), while ELM 4-440 belongs to the ELM 4 series (base product ELM4-4). Series selection may be driven by existing design documentation or procurement specifications.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-440 be used as a direct replacement for ELM 7-11MM?

A: ELM 4-440 qualifies as a parametric equivalent substitute. The 0.010" (0.254mm) length difference must be evaluated against specific PCB clearance and component height requirements in your application. Both parts share identical LED type (T1), material (Black PVC), configuration (3mm, 2-lead), orientation (vertical), and compliance ratings (ROHS3, MSL 1).

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

A: ELM 7-11MM measures 0.430" (10.92mm) while ELM 4-440 measures 0.440" (11.18mm). This 0.010" (0.254mm) difference falls within standard mechanical tolerances for LED standoff components. The impact on your design depends on PCB layout constraints, component spacing, and clearance requirements specific to your application.

Q: Are both parts manufactured by the same company?

A: Yes, both ELM 7-11MM and ELM 4-440 are manufactured by Bivar Inc., ensuring consistent quality standards and material specifications.

Q: Do these parts have different packaging requirements?

A: Both parts are supplied in Bag packaging format with identical moisture sensitivity levels (MSL 1, Unlimited). Storage and handling procedures are equivalent.

Q: What does the series designation (ELM 7 vs. ELM 4) indicate?

A: Series designation reflects the product line classification within Bivar Inc.'s LED standoff portfolio. ELM 7-11MM belongs to the ELM 7 series, while ELM 4-440 belongs to the ELM 4 series. Both series maintain identical compliance and material specifications for this product category.

Q: Are there any electrical performance differences between these parts?

A: Both parts are passive mechanical components designed to support T1 LED mounting. Electrical performance is determined by the LED component itself, not the standoff. The standoff provides mechanical support and positioning only.
