ELM 3-480 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-480 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.480" (12.19mm) length. This component is constructed from black PVC material and accommodates 3-lead LED configurations. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments.

Substitute parts become necessary when the original specification requires alternative material properties, different length dimensions, or when inventory constraints necessitate functionally equivalent alternatives that meet the same electrical and mechanical requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 3-480 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 3/4 (must match)
• Lead Configuration: 3-Lead (must match)
• Color: Black (must match)
• Mounting Orientation: Vertical (must match)
• RoHS Compliance: ROHS3 (must match)

Secondary Variation Parameters:

• Length: Tolerance range 0.480" to 0.500" (minor dimensional variation acceptable for mechanical fit)
• Material: PVC or Nylon (both acceptable for non-thermal applications)

The ELM 3-500 and H-278C-2 are classified as parametric equivalents because they maintain identical LED type, lead configuration, color, and compliance status while introducing controlled variations in length and material composition. These variations do not compromise functional performance in standard LED mounting applications.

Parameter Comparison

Engineering Selection Recommendations

ELM 3-500 Selection Criteria: The ELM 3-500 is a direct series equivalent within the ELM 3 family. It maintains identical material composition (PVC), lead configuration (3-Lead), and compliance certifications. The length differential of 0.020" (0.51mm) represents a minor dimensional variation suitable for applications where vertical standoff height permits tolerance of ±0.020". This part is recommended when ELM 3-480 inventory is unavailable and mechanical clearance accommodates the increased length.

H-278C-2 Selection Criteria: The H-278C-2 introduces material substitution (Nylon vs. PVC) and lead configuration change (2-Lead vs. 3-Lead). This part is suitable only for applications where the circuit design requires 2-lead configuration and where nylon material properties are acceptable. The length matches ELM 3-500 at 0.500" (12.70mm). Selection of this part requires confirmation that the application circuit supports 2-lead LED mounting.

All substitute parts maintain Active product status and ROHS3 compliance, ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can ELM 3-500 directly replace ELM 3-480 in all applications?

A: ELM 3-500 is suitable for replacement when the application mechanical design accommodates the 0.020" (0.51mm) length increase. Both parts share identical LED type (T1 3/4), lead configuration (3-Lead), material (PVC), and compliance status. Verify that the increased standoff height does not interfere with PCB clearance or component spacing requirements.

Q: What is the primary difference between ELM 3-500 and H-278C-2?

A: The primary difference is lead configuration. ELM 3-500 provides 3-Lead configuration, while H-278C-2 provides 2-Lead configuration. Secondary difference is material: ELM 3-500 uses PVC, H-278C-2 uses Nylon. Both share identical length (0.500") and LED type (T1 3/4). Selection depends on circuit design requirements for lead count.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. ELM 3-480, ELM 3-500, and H-278C-2 are all ROHS3 compliant. This ensures compatibility with current manufacturing standards and environmental regulations across all three options.

Q: What packaging format is used for all parts?

A: All three parts are supplied in Bag packaging format. No special handling or packaging conversion is required when substituting between these parts.

Q: Can H-278C-2 be used as a substitute if the application requires 3-Lead configuration?

A: No. H-278C-2 provides 2-Lead configuration and cannot be substituted in applications requiring 3-Lead LED mounting. The lead configuration difference is a critical parameter that determines circuit compatibility.

Q: What is the moisture sensitivity level for H-278C-2?

A: H-278C-2 has Moisture Sensitivity Level listed as Not Applicable, indicating that nylon material does not require moisture-sensitive device handling protocols. ELM 3-480 and ELM 3-500 both have MSL 1 (Unlimited), also indicating no special moisture handling requirements.
