Key Parameters

Substitute Part Grouping Explanation

The ELM 2-350 qualifies as a parametric equivalent based on the following critical parameters that determine substitution compatibility:

• LED Type: Both parts support T1 LED form factors
• Material Composition: Both are constructed from black PVC
• Moisture Sensitivity Level: Both maintain MSL 1 (Unlimited), indicating identical environmental tolerance
• RoHS Compliance: Both meet ROHS3 requirements
• Manufacturer: Both are produced by Bivar Inc., ensuring consistent design and quality standards

The primary variation between these parts is the length dimension: the ELM 2-350 measures 0.350" (8.89mm) compared to the ELM 5-345 at 0.345" (8.76mm), representing a 0.005" (0.13mm) difference. This dimensional tolerance falls within acceptable mechanical variation for T1 LED standoff mounting applications where precise height specifications allow for minor dimensional adjustments.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 5-345 and ELM 2-350 maintain active product status and full RoHS3 compliance, indicating ongoing manufacturer support and regulatory qualification. Selection between these parts should be based on dimensional requirements specific to the application circuit board layout and mechanical assembly constraints. The 0.005" (0.13mm) length differential requires evaluation against available mounting height tolerances in the target design. Both components meet identical moisture sensitivity and environmental performance criteria, ensuring equivalent reliability in operational conditions.

Frequently Asked Questions (FAQ)

Q: Can the ELM 2-350 be substituted directly for the ELM 5-345 in an existing design?

A: Direct substitution depends on the available mechanical height tolerance in your circuit board assembly. The ELM 2-350 is 0.005" (0.13mm) taller than the ELM 5-345. Verify that your design accommodates this dimensional difference before implementing the substitution.

Q: Are there any electrical differences between these T1 LED standoffs?

A: No. Both parts are identical in their support for T1 LED form factors and share equivalent electrical characteristics as T1 LED mounting hardware.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ELM 5-345 and ELM 2-350 are ROHS3 compliant and carry MSL 1 (Unlimited) rating, indicating equivalent environmental qualification and regulatory status.

Q: What is the significance of the ELM series designation difference (ELM 5 versus ELM 2)?

A: The series designation indicates different product lines within the Bivar Inc. LED standoff portfolio. Despite different series classifications, both parts meet identical performance parameters for T1 LED mounting applications.

Q: Which part has better current inventory availability?

A: The ELM 2-350 maintains significantly higher inventory at 3,507 pieces compared to 950 pieces for the ELM 5-345. For supply chain planning purposes, the ELM 2-350 offers improved availability when substitution is technically feasible.
