ELM 4-465 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-465 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.465" (11.81mm) length. This component is constructed from black PVC material and accommodates 3MM LED configurations with 2-lead connections. The part maintains Active product status and is RoHS3 compliant, making it suitable for current production environments. Substitute parts are identified when inventory constraints, lead time requirements, or specific application geometry necessitate alternative components that maintain functional equivalence within defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-465 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Manufacturer: Bivar Inc.
• LED Type: T1
• Material: Black PVC
• Configuration: 3MM 2-Lead Vertical Mount
• Color: Black
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Length: The ELM 5-485 substitute part operates at 0.485" (12.32mm), representing a 0.020" (0.51mm) dimensional increase from the primary part. This variation falls within the tolerance envelope for vertical standoff applications where precise height matching is not a critical constraint.

The ELM 5-485 maintains all mandatory electrical and material specifications while differing only in the standoff length dimension, qualifying it as a parametric equivalent for applications where the increased height does not conflict with PCB layout or mechanical assembly requirements.

Engineering Selection Recommendations

Primary Part Selection (ELM 4-465): Select the ELM 4-465 when the specified 0.465" (11.81mm) standoff height is a design requirement. This part is Active status with full RoHS3 compliance and unlimited moisture sensitivity rating, supporting immediate production deployment.

Substitute Part Selection (ELM 5-485): The ELM 5-485 serves as a functional substitute when the ELM 4-465 is unavailable or when lead time constraints require alternative sourcing. The 0.020" (0.51mm) length increase must be evaluated against PCB layout clearances, component spacing, and mechanical assembly constraints. Both parts maintain identical electrical specifications, material composition, and regulatory compliance status.

Compliance Considerations: Both parts satisfy ROHS3 compliance requirements and carry MSL 1 (Unlimited) ratings, eliminating moisture sensitivity as a selection differentiator. ECCN classification (EAR99) and HTSUS coding (3926.90.9985) are identical across both parts.

Frequently Asked Questions (FAQ)

Q: Can the ELM 5-485 be used as a direct replacement for the ELM 4-465?

A: The ELM 5-485 is a parametric equivalent with all electrical and material specifications matching the ELM 4-465. The only difference is the standoff length: 0.485" versus 0.465". Direct substitution is permissible only when the additional 0.020" height does not conflict with PCB layout, component clearances, or mechanical assembly specifications.

Q: What is the significance of the series designation change from ELM 4 to ELM 5?

A: The series designation reflects the manufacturer's product line organization. The ELM 4 and ELM 5 series both contain T1 LED standoffs in black PVC with identical electrical and material properties. The series change corresponds to the dimensional variation in standoff length.

Q: Are there any electrical performance differences between these parts?

A: No. Both the ELM 4-465 and ELM 5-485 are passive mechanical standoffs for T1 LED mounting. They contain no active electrical components and do not affect circuit performance. Electrical compatibility is determined solely by the LED component specifications, not the standoff.

Q: How does the length difference affect PCB assembly?

A: The 0.020" (0.51mm) length increase in the ELM 5-485 raises the LED component height above the PCB surface. This must be evaluated against available vertical clearance in the enclosure or assembly. If the design includes tight height constraints or component stacking, the dimensional difference becomes a critical selection factor.

Q: Are both parts available in the same packaging format?

A: Yes. Both the ELM 4-465 and ELM 5-485 are supplied in Bag packaging, maintaining consistency in receiving, storage, and handling procedures.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are RoHS3 compliant, carry MSL 1 (Unlimited) ratings, and share identical ECCN (EAR99) and HTSUS (3926.90.9985) classifications. Regulatory and environmental compliance is equivalent across both parts.
