ELM 4-11MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-11MM 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 packages with 2-lead configurations. The part maintains Active product status and is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative components that maintain functional equivalence within the allowed mechanical and electrical parameters of this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-11MM is determined by strict adherence to the following parameters:

Critical Parameters (Must Match):

• LED Type: T1
• Material: Black PVC
• LED Package Size: 3mm
• Lead Configuration: 2-Lead
• Mounting Orientation: Vertical (SR VERT)
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Allowable Variation Parameter:

• Length: Mechanical height tolerance within the ELM 4 series range

The ELM 4-440 qualifies as a parametric equivalent because it maintains all critical parameters while varying only in length specification (0.440" vs. 0.430"). Both parts belong to the ELM 4 series and share identical material composition, LED accommodation, and compliance certifications.

Engineering Selection Recommendations

ELM 4-11MM Selection Criteria:

• Primary choice when 0.430" (10.92mm) mounting height is specified in design documentation
• Current inventory: 846 Pcs New Original In Stock
• Maintains ROHS3 compliance and MSL 1 rating

ELM 4-440 Selection Criteria:

• Acceptable substitute when design allows 0.440" (11.18mm) mounting height tolerance
• Higher inventory availability: 991 Pcs New Original In Stock
• Maintains identical compliance certifications and material specifications
• Suitable for applications where the 0.010" (0.26mm) length differential does not impact PCB layout or mechanical clearance

Both parts maintain Active product status and full regulatory compliance. Selection between these parts should be based on specific mounting height requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-440 be used in place of ELM 4-11MM?

A: ELM 4-440 is a parametric equivalent within the allowed mechanical tolerance of the ELM 4 series. Substitution is valid when the design accommodates the 0.010" (0.26mm) additional length. Verify PCB layout clearance and mechanical constraints before implementation.

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

A: The only difference is the standoff length: ELM 4-11MM measures 0.430" (10.92mm), while ELM 4-440 measures 0.440" (11.18mm). All other specifications—material, LED type, lead configuration, compliance ratings, and mounting orientation—are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both ELM 4-11MM and ELM 4-440 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What does the "2LD" designation indicate?

A: The "2LD" designation indicates a 2-lead configuration, which is the standard electrical connectivity for T1 LED standoffs in this series.

Q: Can these parts be used interchangeably in all applications?

A: Interchangeability depends on design specifications. The 0.010" length difference may be critical in space-constrained applications or where precise mounting height is required. Consult design documentation to confirm tolerance acceptance.

Q: What is the packaging format for these parts?

A: Both parts are supplied in Bag packaging format.
