ELM 3-395 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-395 is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.395" (10.03mm) vertical mounting height. This component is classified as an active product and serves as a mechanical support and alignment fixture for T1 3/4 LED assemblies in vertical orientation.

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or when design specifications permit tolerance variations within the allowed mechanical parameters. The ELM 3-395 maintains compatibility with substitute parts that share identical LED form factor (T1 3/4), material composition (PVC), color (Black), and acceptable length tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 3-395 is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• LED Form Factor: T1 3/4 (mandatory match)
• Material: Black PVC (mandatory match)
• Manufacturer: Bivar Inc. (same product family)
• RoHS Status: ROHS3 Compliant (mandatory match)
• Moisture Sensitivity Level: 1 (Unlimited) (mandatory match)

Allowable Variation Parameter:

• Length: 0.395" ± tolerance within the ELM series range (0.385" to 0.390" acceptable)

The ELM 3-395 has two qualified substitutes: ELM 1-10MM and ELM 1-385. Both parts maintain identical LED form factor, material, color, and compliance certifications. Length variations of ±0.010" fall within acceptable mechanical tolerances for vertical LED standoff applications where precise height matching is not a critical design constraint.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

All three parts (ELM 3-395, ELM 1-10MM, and ELM 1-385) maintain active product status with Bivar Inc., ensuring continued manufacturer support and supply chain availability. All parts carry ROHS3 compliance certification and MSL 1 (Unlimited) rating, confirming equivalent environmental and storage qualification.

Length Variation Consideration:

The length differential between ELM 3-395 (10.03mm) and its substitutes ranges from 0.13mm (ELM 1-10MM) to 0.25mm (ELM 1-385). Selection between these parts depends on whether the application design permits this vertical height variation. In applications where LED standoff height is non-critical to circuit board layout or optical alignment, all three parts are functionally equivalent.

Inventory and Availability:

Current stock levels are: ELM 3-395 (752 pcs), ELM 1-10MM (947 pcs), and ELM 1-385 (750 pcs). Selection may be influenced by immediate availability requirements.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-10MM and ELM 1-385 be used interchangeably with ELM 3-395?

A: Yes, both parts are qualified substitutes. All three parts share identical LED form factor (T1 3/4), material (Black PVC), and compliance certifications (ROHS3, MSL 1). The length variation of 0.010" to 0.025" is within acceptable mechanical tolerance for vertical LED standoff applications.

Q: What is the maximum allowable length variation between these parts?

A: The length range spans from 0.385" (ELM 1-385) to 0.395" (ELM 3-395), representing a 0.010" maximum variation. This tolerance is acceptable for standard LED mounting applications where precise height matching is not a critical design parameter.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. ELM 3-395, ELM 1-10MM, and ELM 1-385 all carry ROHS3 Compliant certification, confirming equivalent environmental compliance across all three part numbers.

Q: Do these parts require special storage or handling?

A: No. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard component storage conditions apply.

Q: What is the difference between the ELM 3 and ELM 1 series designations?

A: The series designation reflects internal Bivar Inc. product line organization. Both series maintain identical mechanical and electrical specifications for T1 3/4 LED standoffs. Series designation does not affect functional compatibility or substitution eligibility.

Q: Can I mix ELM 3-395, ELM 1-10MM, and ELM 1-385 in the same assembly?

A: Yes. All three parts are mechanically and functionally equivalent. Mixed usage is permissible in applications where uniform LED standoff height is not a critical design requirement.
