ELM 1-7MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-7MM is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.280" (7.11mm) length specification. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where dimensional and material tolerances permit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 1-7MM is determined by the following parameters:

Primary Compatibility Criteria:

• LED Type: T1 3/4 (must match)
• Material: Black PVC (must match)
• Mounting Style: Vertical (must match)
• RoHS Status: ROHS3 Compliant (must match)
• Moisture Sensitivity Level: 1 (Unlimited) (must match)

Allowable Variation:

• Length tolerance: Dimensional variation within 0.005" (0.127mm) is permissible for mechanical fit in standard mounting applications

The ELM 3-285 qualifies as a parametric equivalent based on matching LED type, material composition, mounting orientation, and compliance certifications. The length differential of 0.005" (0.24mm) falls within acceptable mechanical tolerance ranges for vertical standoff applications.

Engineering Selection Recommendations

ELM 1-7MM Selection: Use the ELM 1-7MM when the original design specification calls for a 0.280" (7.11mm) length standoff. This part is Active and ROHS3 compliant, supporting current production requirements.

ELM 3-285 Selection: The ELM 3-285 serves as a direct substitute when the 0.005" (0.24mm) length increase is mechanically acceptable within the application's tolerance stack. Both parts share identical LED type, material, mounting orientation, and compliance certifications. The ELM 3-285 maintains Active product status and ROHS3 compliance.

Compliance Considerations: Both parts satisfy ROHS3 requirements and carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special storage or handling requirements. Selection between these parts depends solely on mechanical fit requirements within the target application.

Frequently Asked Questions (FAQ)

Q: Can ELM 3-285 replace ELM 1-7MM in all applications?

A: The ELM 3-285 is mechanically compatible when the 0.005" (0.24mm) length increase does not violate application constraints. Verify that the increased standoff height does not interfere with adjacent components or exceed PCB clearance specifications.

Q: What is the significance of the length difference between these parts?

A: The ELM 1-7MM measures 0.280" (7.11mm) while the ELM 3-285 measures 0.285" (7.24mm). This 0.005" (0.24mm) difference affects vertical spacing in the assembly. Applications with tight vertical clearance requirements must account for this variation.

Q: Are both parts RoHS compliant?

A: Yes. Both ELM 1-7MM and ELM 3-285 are ROHS3 compliant, meeting current environmental and regulatory standards for electronic component manufacturing.

Q: Do these parts require special handling or storage?

A: No. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are necessary during storage, handling, or assembly.

Q: What packaging format is used for these parts?

A: Both parts are supplied in Bag packaging, suitable for standard component storage and distribution workflows.

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

A: No electrical differences exist. Both parts are mechanical standoffs for T1 3/4 LED components. Electrical performance is determined by the LED component itself, not the standoff.
