ELM 3-325 LED Standoff Equivalent and Substitute Parts

Part Overview

The ELM 3-325 is an active-status T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black PVC material with a 0.325" (8.26mm) length specification. This component is ROHS3 compliant and maintains MSL Level 1 rating. Alternative parts become necessary when specific inventory availability constraints occur or when dimensional tolerance variations within the allowed parameter range are acceptable for the application requirements.

Key Parameters

Substitute Part Grouping Explanation

The ELM 3-335 qualifies as a parametric equivalent based on the following allowable substitution criteria within the ELM 3 series:

Critical Common Parameters (Substitution Basis):

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

Dimensional Variance:

• Length tolerance: 0.325" (8.26mm) to 0.335" (8.51mm)

The dimensional difference of 0.010" (0.25mm) represents a controlled length variation within the mechanical design tolerance of the ELM 3 standoff family. This variance falls within standard LED standoff manufacturing tolerances and does not affect electrical performance or physical mounting compatibility for applications where length tolerance is not a critical constraint.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 3-325 and ELM 3-335 maintain active product status with full ROHS3 compliance and MSL Level 1 rating. Selection between these parts should be driven by application-specific length requirements and inventory availability. The ELM 3-325 provides the shorter profile at 0.325" (8.26mm), while the ELM 3-335 offers a longer standoff at 0.335" (8.51mm). Both components are suitable for applications where regulatory compliance with ROHS3 standards and unlimited moisture exposure are required.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the ELM 3-325 and ELM 3-335? A: The primary difference is the physical length specification: ELM 3-325 measures 0.325" (8.26mm), while the ELM 3-335 measures 0.335" (8.51mm). All other electrical, mechanical, and compliance parameters remain identical.

Q: Can the ELM 3-335 be used as a direct replacement for the ELM 3-325? A: Direct substitution is possible only if the application design accommodates the additional 0.010" (0.25mm) length variance. The components share identical electrical properties and regulatory compliance status.

Q: Are both parts equally available? A: Inventory levels differ between the two parts. Verify current stock status with your supplier before design finalization.

Q: What compliance certifications apply to both parts? A: Both the ELM 3-325 and ELM 3-335 are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Are there any restrictions on using these parts interchangeably? A: Interchangeability is restricted solely by mechanical design constraints. If the application design specifies a maximum or minimum standoff height, the dimensional variance must be evaluated against those constraints.
