ELM 2-400 Equivalent & Substitute Parts

Part Overview

The ELM 2-400 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.400" (10.16mm) length specification. The part is currently Active in product status and maintains full RoHS3 compliance with MSL 1 rating, indicating unlimited moisture sensitivity tolerance.

Substitute parts are identified when equivalent functional performance can be achieved through alternative models that maintain compatibility with the same LED form factor, material composition, and electrical characteristics while accommodating minor dimensional variations within acceptable engineering tolerances.

Key Parameters

Substitute Part Grouping Explanation

The ELM 2-400 accepts the ELM 5-390 as a parametric equivalent based on the following substitution criteria:

Matching Parameters:

• LED Form Factor: Both utilize T1 LED specification
• Material Composition: Both constructed from black PVC
• Mounting Configuration: Both designed for vertical standoff mounting
• Regulatory Compliance: Both maintain ROHS3 compliance
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)
• Manufacturer: Both produced by Bivar Inc.

Dimensional Consideration: The primary dimensional difference is length specification: ELM 2-400 measures 0.400" (10.16mm) while ELM 5-390 measures 0.390" (9.91mm). This 0.010" (0.25mm) variation falls within acceptable mechanical tolerance ranges for standoff applications where precise height matching is not a critical design constraint.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 2-400 and ELM 5-390 maintain Active product status with full regulatory compliance under ROHS3 standards. Selection between these parts should be based on specific application height requirements:

ELM 2-400 Selection: Use when the 0.400" (10.16mm) standoff height is specified in the design documentation or when maximum available height within the T1 PVC standoff series is required.

ELM 5-390 Selection: Use when the 0.390" (9.91mm) standoff height meets application requirements or when component availability from the ELM 5 series is preferred. This part maintains equivalent electrical and mechanical properties with a 0.010" (0.25mm) reduction in overall length.

Both parts carry identical compliance certifications and moisture sensitivity ratings, ensuring equivalent performance in environmental conditions and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can ELM 5-390 be used as a direct replacement for ELM 2-400?

A: The ELM 5-390 functions as a parametric equivalent for the ELM 2-400 in applications where the 0.010" (0.25mm) length difference does not impact circuit board layout or component clearance. Both parts share identical LED type, material, color, and compliance specifications.

Q: What is the significance of the length difference between these parts?

A: The ELM 2-400 provides 0.400" (10.16mm) height while the ELM 5-390 provides 0.390" (9.91mm) height. This 0.010" (0.25mm) variation represents a 2.5% dimensional difference. Applications with tight vertical clearance constraints or precise height matching requirements should use the specified part number rather than a substitute.

Q: Are both parts RoHS compliant?

A: Yes. Both the ELM 2-400 and ELM 5-390 maintain ROHS3 compliance and carry identical Moisture Sensitivity Level 1 (Unlimited) ratings, ensuring equivalent environmental and regulatory performance.

Q: What packaging format is used for these parts?

A: Both the ELM 2-400 and ELM 5-390 are supplied in Bag packaging format suitable for standard component handling and storage procedures.

Q: Are there any electrical performance differences between these standoff models?

A: No electrical performance differences exist between these parts. Both are T1 LED standoffs with identical material composition and regulatory compliance. Differences are limited to the mechanical length specification.
