ELM 3-7MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-7MM is an active T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.276" (7.00mm) length. This component serves as a mechanical mounting solution for LED applications requiring precise vertical orientation. The availability of alternative models within the ELM 3 series becomes necessary to accommodate design variations, inventory constraints, or dimensional requirements across different manufacturing batches or applications.

Key Parameters

Substitute Part Grouping Explanation

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

• LED Type: Both parts must be T1 3/4 LED standoffs
• Material: Both parts must use black PVC construction
• Manufacturer: Both parts must be manufactured by Bivar Inc.
• Series: Both parts must belong to the ELM 3 product series
• Compliance Status: Both parts must maintain ROHS3 Compliant certification and MSL 1 rating

The primary difference between the main part (ELM 3-7MM) and its substitute (ELM 3-285) is the length specification. The ELM 3-285 provides a 0.285" (7.24mm) length compared to the 0.276" (7.00mm) of the main part, representing a 0.009" (0.24mm) dimensional variation. This dimensional difference permits substitution in applications where the mechanical tolerance allows for this minor height variation.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 3-7MM and ELM 3-285 are active, ROHS3 compliant products with identical material composition, LED type, and moisture sensitivity characteristics. The selection between these parts depends exclusively on the dimensional tolerance of the application:

• ELM 3-7MM is selected when the 0.276" (7.00mm) length specification is required.
• ELM 3-285 is selected when a 0.285" (7.24mm) length accommodates the design requirements.

Both parts share identical compliance certifications, MSL ratings, and series designation, confirming their functional equivalence within the specified dimensional constraints.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 3-7MM and ELM 3-285?

A: The primary difference is the physical length. ELM 3-7MM measures 0.276" (7.00mm), while ELM 3-285 measures 0.285" (7.24mm), a 0.009" (0.24mm) variation.

Q: Can ELM 3-285 be used as a direct replacement for ELM 3-7MM?

A: ELM 3-285 can be used as a substitute only if the application design tolerance allows for a 0.009" (0.24mm) increase in standoff height. Both parts are identical in all other parameters including LED type, material, and compliance ratings.

Q: Do both parts have the same compliance certifications?

A: Yes. Both ELM 3-7MM and ELM 3-285 are ROHS3 compliant with MSL 1 (Unlimited) rating and identical ECCN and HTSUS classifications.

Q: Are the packaging formats identical?

A: Yes. Both parts are supplied in bag packaging with identical handling and storage requirements.

Q: What if the 0.009" dimensional difference is critical to my application?

A: If the design tolerance does not permit the 0.009" (0.24mm) variation, ELM 3-7MM must be used. Substitution is only valid when the mechanical design accommodates the alternative length specification.
