ELM 4-400

Part Overview

The ELM 4-400 is a T1 LED standoff manufactured by Bivar Inc., constructed from black PVC material with a 0.400" (10.16mm) length. This component is used as a mechanical support and positioning element for T1 LED assemblies in vertical mounting applications. The part maintains Active product status and is currently in stock with 747 pieces available as new original inventory.

Equivalent substitute parts become necessary when the primary ELM 4-400 is unavailable or when design specifications permit alternative standoff heights within the same product family while maintaining functional compatibility with T1 LED mounting requirements.

Key Parameters

Substitute Part Grouping Explanation

The ELM 5-390 qualifies as a parametric equivalent to the ELM 4-400 based on the following substitution criteria:

Identical Parameters:

• Manufacturer: Bivar Inc.
• LED Type: T1
• Color: Black
• Material: PVC
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Packaging: Bag
• ECCN Classification: EAR99
• HTSUS Code: 3926.90.9985

Variable Parameter:

• Length: ELM 4-400 features 0.400" (10.16mm); ELM 5-390 features 0.390" (9.91mm)

The length differential of 0.010" (0.25mm) permits substitution where design specifications allow for standoff height variation within tolerance. Both parts support identical T1 LED mounting geometry and maintain full compliance with regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Both ELM 4-400 and ELM 5-390 maintain Active product status, indicating full manufacturer support and ongoing availability. Both components achieve ROHS3 compliance and MSL Level 1 classification, meeting regulatory and environmental standards for unrestricted use.

Selection between these parts is determined by standoff height requirements. The ELM 4-400 provides 0.400" height while the ELM 5-390 provides 0.390" height. The 0.010" differential accommodates design specifications that permit minor height variations in T1 LED mounting assemblies.

Frequently Asked Questions (FAQ)

What determines whether ELM 5-390 can substitute for ELM 4-400?

Substitution is valid when design specifications permit a 0.010" reduction in standoff height. Both parts maintain identical LED type (T1), color (Black), material (PVC), and regulatory compliance status.

Are regulatory certifications identical between these parts?

Yes. Both ELM 4-400 and ELM 5-390 carry ROHS3 compliance and MSL Level 1 rating. Both are classified under ECCN EAR99 and HTSUS code 3926.90.9985.

What is the impact of the 0.010" length difference?

The 0.390" length of ELM 5-390 is 0.010" shorter than the 0.400" length of ELM 4-400. This dimensional difference affects standoff height in vertical mounting applications and must be evaluated against design tolerances.

How do I determine if the height difference is acceptable for my application?

Consult the printed circuit board assembly drawing to confirm allowable standoff height tolerance. If the tolerance range encompasses both 0.400" and 0.390", substitution is permissible.

What packaging format do these parts use?

Both ELM 4-400 and ELM 5-390 are supplied in Bag packaging.
