ELM 5-355 Equivalent & Substitute Parts

Part Overview

The ELM 5-355 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.355" (9.02mm) vertical mounting height. This component is classified as active product status and serves as a mechanical support and alignment component for T1 LED packages in vertical PCB mount applications. Alternative models are necessary when specific height requirements differ slightly from the 0.355" specification, or when inventory constraints require sourcing from available stock alternatives that maintain functional compatibility within acceptable tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 5-355 are qualified based on the following key parameters:

• LED Type: T1 (standardized package format)
• Material: Black PVC (consistent with environmental and mechanical requirements)
• Mounting Orientation: Vertical, single-row (SR VERT)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity: MSL 1 (Unlimited)

The ELM 2-350 and ELM 2-365 are parametric equivalents that maintain compatibility through identical LED type, material composition, color, and compliance certifications. The primary variation is in the mounting height dimension, with tolerances of ±0.005" within the critical functional range. Length differences of 0.005" (ELM 2-350 at 0.350") and 0.010" (ELM 2-365 at 0.365") from the main specification fall within acceptable mechanical substitution limits for vertical LED standoff applications where height variation does not compromise circuit board layout or solder joint integrity.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with ROHS3 compliance and identical moisture sensitivity ratings. Selection between ELM 5-355, ELM 2-350, and ELM 2-365 is determined by mounting height requirements within the 0.350" to 0.365" range. The ELM 2-350 provides the minimum height alternative at 0.350" (8.89mm), suitable for applications with space constraints. The ELM 5-355 at 0.355" (9.02mm) serves as the nominal specification. The ELM 2-365 at 0.365" (9.27mm) accommodates designs requiring maximum standoff height within this product family. All substitutes are manufactured by Bivar Inc., ensuring consistent quality and material composition.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-350 and ELM 2-365 be used interchangeably with ELM 5-355 in the same application?

A: The ELM 2-350 and ELM 2-365 are substitutes when application design tolerates the 0.005" (0.127mm) reduction in height or 0.010" (0.254mm) increase in height, respectively. Design schematics and mechanical drawings must confirm that height variation does not affect PCB layout, component clearance, or solder joint characteristics.

Q: What is the significance of the ELM 5 and ELM 2 series designations?

A: The series designation identifies the product family and manufacturing lineage. Both ELM 5 and ELM 2 series maintain identical T1 LED compatibility and PVC material specifications, with differences limited to series-specific design iterations and inventory streams.

Q: Are all three parts RoHS compliant and suitable for regulated applications?

A: Yes. All three parts—ELM 5-355, ELM 2-350, and ELM 2-365—are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, making them suitable for applications requiring regulatory compliance with environmental and reliability standards.

Q: How do length variations affect LED standoff performance?

A: Length variations within the 0.350" to 0.365" range maintain consistent T1 LED contact geometry and vertical alignment for PCB-mounted applications. The 0.015" (0.381mm) total variation across the product range represents less than 2% deviation from nominal height and does not affect electrical performance or mechanical fit within standard LED mounting hole specifications.

Q: What packaging format is used for these parts?

A: All three substitute parts are supplied in bag packaging, consistent with standard component handling and bulk distribution practices for passive mechanical components.
