ELM 3-120 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-120 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.120" (3.05mm) length specification. This component is constructed from black PVC material and accommodates standard T1 3/4 LED packages with a 3-lead configuration. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments. Substitute parts are identified when inventory constraints occur or when design specifications allow for minor dimensional variations within the established parameter tolerance range.

Substitute Part Grouping Explanation

Substitute parts for the ELM 3-120 are qualified based on the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 3/4 (fixed requirement)
• Material: PVC (fixed requirement)
• Color: Black (fixed requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (fixed requirement)
• RoHS Status: ROHS3 Compliant (fixed requirement)
• Manufacturer: Bivar Inc. (fixed requirement)

Secondary Substitution Criteria:

• Length tolerance: 0.118" to 0.120" (3.00mm to 3.05mm)
• Lead Configuration: 2-Lead or 3-Lead configurations
• Series designation: ELM 1 or ELM 3 series

The ELM 3-120 accepts substitutes ELM 1-3MM and ELM 3-3MM based on dimensional compatibility within the specified length tolerance and matching core electrical and material specifications.

Parameter Comparison

Engineering Selection Recommendations

ELM 1-3MM Substitution: The ELM 1-3MM qualifies as a parametric equivalent to the ELM 3-120 with identical length specification (0.120" / 3.05mm) and matching core material, color, and compliance certifications. The primary distinction is the 2-lead configuration versus the 3-lead configuration of the main part. This substitute is suitable when circuit design accommodates a 2-lead LED standoff architecture. Both parts maintain Active product status and ROHS3 compliance.

ELM 3-3MM Substitution: The ELM 3-3MM maintains series consistency with the ELM 3-120 and preserves the 3-lead configuration. The length specification is 0.118" (3.00mm), representing a 0.002" (0.05mm) dimensional reduction within acceptable tolerance parameters for LED standoff applications. This substitute is appropriate when the reduced length does not conflict with mechanical assembly constraints. Both parts maintain Active product status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the ELM 1-3MM replace the ELM 3-120 in all applications?

A: The ELM 1-3MM is dimensionally and materially compatible with the ELM 3-120. However, the 2-lead configuration differs from the 3-lead configuration of the main part. Substitution is valid only when the circuit design supports a 2-lead LED standoff connection.

Q: What is the significance of the length difference between ELM 3-120 and ELM 3-3MM?

A: The ELM 3-3MM has a length of 0.118" (3.00mm) compared to the ELM 3-120 at 0.120" (3.05mm). This 0.002" (0.05mm) difference falls within standard mechanical tolerance for LED standoff applications and does not affect electrical performance or LED type compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both ELM 1-3MM and ELM 3-3MM are ROHS3 compliant, matching the compliance status of the ELM 3-120. All parts are suitable for applications requiring RoHS certification.

Q: What is the Moisture Sensitivity Level for these parts?

A: All three parts—ELM 3-120, ELM 1-3MM, and ELM 3-3MM—carry a Moisture Sensitivity Level of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use ELM 3-3MM as a direct replacement for ELM 3-120?

A: The ELM 3-3MM is a direct substitute for the ELM 3-120 when the 0.002" (0.05mm) length reduction is acceptable within your mechanical assembly design. Both parts share the same series designation (ELM 3), 3-lead configuration, and all material and compliance specifications.

Q: What packaging format is used for these parts?

A: All three parts are supplied in Bag packaging format, consistent with standard component distribution for LED standoff products.
