ELM 4-9MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-9MM is an active T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.350" (8.89mm) length and accommodates T1 LED packages with a 2-lead configuration. The part is ROHS3 compliant and carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the ELM product series, allowing for component interchangeability in applications where dimensional and material specifications align.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 4-9MM are identified based on the following critical parameters that must remain constant for functional equivalence:

Mandatory Matching Parameters:

• LED Type: T1
• Material: Black PVC
• Lead Configuration: 2-Lead
• Manufacturer: Bivar Inc.
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Series designation (ELM 4 vs. ELM 2)
• Length tolerance within mechanical design specifications

The ELM 2-350 and ELM 2-365 are classified as parametric equivalents because they maintain identical LED type, material composition, lead configuration, and compliance certifications. Both parts are manufactured by Bivar Inc. and share the same MSL rating and RoHS status as the primary part.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-350: This part is a direct dimensional and functional equivalent to the ELM 4-9MM, maintaining identical length specifications of 0.350" (8.89mm). Both parts share all critical electrical and mechanical parameters. Selection between ELM 4-9MM and ELM 2-350 depends on series availability and inventory status. Both are active products with ROHS3 compliance and unlimited moisture sensitivity ratings.

ELM 2-365: This part differs from the ELM 4-9MM in length specification, measuring 0.365" (9.27mm) compared to 0.350" (8.89mm). This 0.015" (0.38mm) dimensional difference may affect mechanical fit in applications with tight vertical clearance constraints. All other electrical and compliance parameters remain equivalent. Selection of ELM 2-365 is appropriate only when the increased length does not conflict with mechanical design requirements.

All three parts maintain active product status and full ROHS3 compliance, ensuring long-term availability and regulatory conformance for production applications.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-350 be used as a direct replacement for ELM 4-9MM?

A: Yes. The ELM 2-350 maintains identical length (0.350" / 8.89mm), LED type (T1), material (Black PVC), lead configuration (2-Lead), and all compliance certifications. No design modifications are required for substitution.

Q: What is the key difference between ELM 2-365 and the other substitute parts?

A: The ELM 2-365 has a length of 0.365" (9.27mm), which is 0.015" (0.38mm) longer than both the ELM 4-9MM and ELM 2-350. This dimensional difference must be evaluated against mechanical clearance requirements in the application. All other parameters remain equivalent.

Q: Are all three parts RoHS compliant?

A: Yes. The ELM 4-9MM, ELM 2-350, and ELM 2-365 are all ROHS3 compliant and carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: What does MSL 1 (Unlimited) mean for component handling?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity limitations. Standard storage and handling procedures apply without special environmental controls or time restrictions.

Q: Can series designation (ELM 4 vs. ELM 2) affect compatibility?

A: Series designation reflects product line organization within the Bivar Inc. portfolio. Substitution is determined by matching electrical and mechanical parameters, not series number. Both ELM 4 and ELM 2 series parts with identical specifications are functionally equivalent.

Q: What packaging format is used for these parts?

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