ELM 4-355 Equivalent & Substitute Parts

Part Overview

The ELM 4-355 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications requiring a 0.355" (9.02mm) height. This component is constructed from black PVC material and is classified as Active product status. Substitute parts become necessary when specific height requirements vary within acceptable tolerances, inventory constraints require alternative sourcing, or design iterations necessitate slightly different standoff dimensions while maintaining core functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of ELM 4-355 is based on the following parameters that must remain consistent across alternative parts:

• LED Type: Must be T1 format
• Material: Must be PVC construction
• Color: Must be black
• RoHS Compliance: Must maintain ROHS3 Compliant status
• Moisture Sensitivity Level: Must be MSL 1 (Unlimited)

The primary variable parameter permitting substitution is the length dimension, which ranges from 0.350" (8.89mm) to 0.365" (9.27mm). Both substitute parts maintain identical material composition, color, LED classification, and regulatory compliance while providing alternative height options within a 0.015" tolerance band centered on the original 0.355" specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ELM 4-355, ELM 2-350, and ELM 2-365—maintain Active product status and full ROHS3 compliance. Each part carries MSL 1 (Unlimited) moisture sensitivity rating, indicating no special handling requirements during storage or assembly. Selection among these components depends on the specific height requirement of the application, as the mechanical dimensions vary within a 0.015" band. Both substitute parts are supported by current manufacturing processes and regulatory certifications equivalent to the primary part.

Frequently Asked Questions (FAQ)

Q: What parameter determines if ELM 2-350 or ELM 2-365 can substitute for ELM 4-355? A: The LED type (T1), material (PVC), color (black), and compliance status (ROHS3) must match. Height is the only allowed variable parameter. ELM 2-350 measures 0.350", ELM 2-365 measures 0.365", and ELM 4-355 measures 0.355", all within a 0.015" tolerance band.

Q: Are there any moisture sensitivity differences between the main part and substitutes? A: No. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating identical environmental handling characteristics.

Q: Can substitute parts be mixed in the same assembly? A: The substitute parts share identical functional and physical characteristics except for length. Design requirements determine whether mixed heights in a single assembly are permissible.

Q: What is the inventory advantage of selecting a substitute part? A: ELM 2-350 has 3507 units in stock and ELM 2-365 has 16125 units in stock, compared to 1084 units for ELM 4-355.

Q: Do the substitute parts have the same packaging specification? A: All parts are packaged in bags as standard.

Q: Are all parts manufactured by the same company? A: Yes. All three parts are manufactured by Bivar Inc.
