ELM 5-9MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 5-9MM 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 MSL Level 1 (Unlimited) moisture sensitivity rating, indicating suitability for standard storage and handling conditions without special precautions.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specification, enabling direct replacement in applications where the core functional requirements remain constant.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 5-9MM are identified based on strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• LED Type: T1
• Material: Black PVC
• Lead Count: 2 LD
• Mounting Orientation: Vertical (SR VERT)
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Length Tolerance Consideration: The ELM 5-9MM specifies a length of 0.350" (8.89mm). Substitute parts are grouped into two categories based on length specification:

1. Exact Length Match (0.350" / 8.89mm): ELM 2-350
2. Alternate Length (0.365" / 9.27mm): ELM 2-365

Both substitute parts maintain identical electrical and material specifications while differing only in standoff length. Selection between these substitutes depends on specific PCB clearance and assembly height requirements of the target application.

Engineering Selection Recommendations

ELM 2-350 Selection Criteria: Select ELM 2-350 when exact dimensional matching to the ELM 5-9MM is required. This substitute provides identical length specification (0.350" / 8.89mm) and maintains all electrical and material parameters. Both parts are active products with ROHS3 compliance and MSL Level 1 rating, ensuring equivalent regulatory and environmental performance.

ELM 2-365 Selection Criteria: Select ELM 2-365 when application requirements permit a 0.015" (0.38mm) increase in standoff length. This substitute maintains all electrical and material specifications while providing additional PCB clearance. ELM 2-365 carries identical compliance certifications and MSL rating as the main part.

Inventory Availability: All three parts maintain active product status with current stock availability. ELM 2-350 and ELM 2-365 demonstrate higher inventory levels (3,507 and 16,125 units respectively) compared to the main part (738 units), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-350 be used as a direct replacement for ELM 5-9MM?

A: Yes. ELM 2-350 provides identical electrical and mechanical specifications, including T1 LED type, black PVC material, 2-lead configuration, vertical mounting orientation, and 0.350" (8.89mm) length. Both parts are ROHS3 compliant with MSL Level 1 rating.

Q: What is the primary difference between ELM 2-350 and ELM 2-365?

A: The only difference is standoff length. ELM 2-350 measures 0.350" (8.89mm), while ELM 2-365 measures 0.365" (9.27mm). All other parameters, including LED type, material, lead count, and compliance ratings, are identical.

Q: When should ELM 2-365 be selected over ELM 2-350?

A: Select ELM 2-365 when the application design requires additional clearance between the LED and the PCB surface. The 0.015" (0.38mm) additional length accommodates designs with tighter component spacing or specific thermal management requirements.

Q: Are all three parts RoHS3 compliant?

A: Yes. ELM 5-9MM, ELM 2-350, and ELM 2-365 are all ROHS3 compliant, meeting regulatory requirements for restricted substances in electrical and electronic equipment.

Q: What does MSL Level 1 (Unlimited) mean for these parts?

A: MSL Level 1 indicates unlimited shelf life under standard storage conditions. These parts do not require special moisture control measures, desiccant packaging, or time-limited storage protocols.

Q: Can these parts be used interchangeably in the same PCB design?

A: ELM 2-350 provides direct interchangeability with ELM 5-9MM due to identical dimensions. ELM 2-365 can be used if the PCB layout accommodates the additional 0.015" (0.38mm) height without component interference or design constraint violations.
