ELM 7-120 Equivalent and Substitute Parts

Part Overview

The ELM 7-120 is an active T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting with a 0.120" (3.05mm) length in black PVC material. This part is compliant with ROHS3 standards and carries an MSL rating of 1 (Unlimited). Alternative models are available to accommodate specific mounting height requirements and inventory availability across different product series within the ELM family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 7-120 are qualified based on the following critical parameters:

Critical Parameters for Substitution:

• LED Type: T1 (all substitutes maintain this specification)
• Material: Black PVC (consistent across all alternatives)
• Mounting Style: Vertical, surface-mount configuration
• Product Status: Active (all alternatives are in active production)
• RoHS Compliance: ROHS3 Compliant (all alternatives meet this requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (all alternatives share this rating)

Variable Parameter:

• Length: The ELM 7-120 features a 0.120" (3.05mm) length. Substitute ELM 4-115 features a 0.115" (2.92mm) length, representing a 0.005" (0.13mm) reduction. This dimensional variation permits substitution in applications where mounting height tolerance accommodates the shorter standoff. The ELM 2-120 maintains identical length specifications.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-120 Selection: The ELM 2-120 is a direct parametric equivalent to the ELM 7-120, offering identical mechanical dimensions and electrical specifications. Both parts carry Active product status, ROHS3 compliance, and equivalent MSL ratings. The ELM 2-120 maintains superior inventory availability (86,435 units) relative to the ELM 7-120 (929 units), making it the preferred selection for applications where series designation does not impose design constraints.

ELM 4-115 Selection: The ELM 4-115 permits substitution only in applications where a 0.005" (0.13mm) reduction in mounting height is acceptable within design tolerance. This part maintains identical LED type, material composition, and compliance certifications. Selection of the ELM 4-115 is suitable where the shorter standoff length does not adversely affect PCB clearance or mechanical fit. Inventory availability for this part (1,684 units) exceeds the main part specification but remains lower than the ELM 2-120.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-120 replace ELM 7-120 in all applications? A: Yes. The ELM 2-120 is a complete parametric equivalent, sharing identical length (0.120"), LED type (T1), material (black PVC), color, and all compliance certifications. No application modifications are required for direct substitution.

Q: What is the critical difference between ELM 7-120 and ELM 4-115? A: The ELM 4-115 features a reduced length of 0.115" (2.92mm) compared to the ELM 7-120 at 0.120" (3.05mm). This 0.005" (0.13mm) dimensional difference is the sole technical distinction. All other parameters—LED type, material, color, and compliance ratings—remain identical.

Q: Is the ELM 4-115 suitable for my application? A: Substitution with ELM 4-115 is appropriate if your design accommodates the 0.005" (0.13mm) shorter mounting height. If your PCB layout, LED clearance, or mechanical assembly depends on the original 0.120" length, the ELM 4-115 is not suitable. In such cases, select ELM 2-120.

Q: Are all three parts RoHS compliant? A: Yes. The ELM 7-120, ELM 2-120, and ELM 4-115 all carry ROHS3 Compliant certification, confirming compliance with restriction of hazardous substances regulations.

Q: Which part offers the best inventory availability? A: The ELM 2-120 provides the highest inventory stock at 86,435 units. The main part ELM 7-120 carries 929 units, and the ELM 4-115 carries 1,684 units.

Q: Do all parts use the same packaging? A: Yes. All three parts are supplied in bag packaging as specified by the manufacturer.
