ELM 3-330 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-330 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.330" (8.38mm) length specification. This component is constructed from black PVC material and accommodates standard 5MM LED configurations with 3-lead design. 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 application-specific dimensional tolerances necessitate alternative sourcing within the ELM 3 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the ELM 3 series is determined by the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Bivar Inc.
• Series: ELM 3
• LED Type: T1 3/4
• Lead Configuration: 3-Lead (3LD)
• Material: Black PVC
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameter (Substitution Basis):

• Length: 0.330" (8.38mm) for ELM 3-330 vs. 0.335" (8.51mm) for ELM 3-335

The ELM 3-335 qualifies as a parametric equivalent because it maintains identical specifications across all mandatory parameters while varying only in length by 0.005" (0.13mm). This dimensional variance falls within the tolerance range for vertical LED standoff mounting applications where minor height adjustments do not compromise functional performance or mechanical fit in standard PCB layouts.

Engineering Selection Recommendations

ELM 3-330 Primary Selection Criteria:

• Specified application requires 0.330" (8.38mm) standoff height
• Design documentation explicitly calls for ELM 3-330 part number
• Current inventory availability: 1162 Pcs New Original In Stock

ELM 3-335 Substitution Criteria:

• Application tolerates 0.335" (8.51mm) standoff height (+0.005" variance)
• ELM 3-330 inventory unavailable or lead time exceeds project requirements
• Current inventory availability: 14653 Pcs New Original In Stock
• Both parts maintain identical Active product status and ROHS3 compliance

Both parts are suitable for production environments requiring ROHS3 compliance and unlimited moisture sensitivity tolerance. Selection between ELM 3-330 and ELM 3-335 is determined solely by dimensional requirements and inventory availability, with no functional or compliance trade-offs.

Frequently Asked Questions (FAQ)

Q: Can ELM 3-335 be used in place of ELM 3-330?

A: ELM 3-335 is a parametric equivalent when the application design permits a 0.005" (0.13mm) increase in standoff height. Both parts share identical LED type (T1 3/4), lead configuration (3-Lead), material (Black PVC), and compliance certifications (ROHS3). Substitution is valid only when PCB layout and mechanical clearances accommodate the longer standoff.

Q: What is the primary difference between these parts?

A: The sole difference is standoff length: ELM 3-330 measures 0.330" (8.38mm), while ELM 3-335 measures 0.335" (8.51mm). All other specifications, including LED type, material composition, lead configuration, and regulatory compliance, are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both ELM 3-330 and ELM 3-335 are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), making them suitable for equivalent regulatory and environmental requirements.

Q: What packaging format is used for these parts?

A: Both parts are supplied in Bag packaging format, consistent with standard component distribution for LED standoff assemblies.

Q: How does the 0.005" length difference affect PCB design?

A: The 0.005" (0.13mm) variance is negligible for most vertical LED mounting applications. However, designs with tight vertical clearance constraints or specific optical alignment requirements must verify that the increased height does not interfere with enclosure geometry, lens positioning, or adjacent components.

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

A: No. Both parts are mechanical standoffs for LED mounting. Electrical performance is determined by the LED component itself, not the standoff. The standoff provides only mechanical positioning and does not affect electrical characteristics.
