ELM 2-125 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 2-125 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.125" (3.18mm) height specification. This component is constructed from black PVC material and accommodates 2-lead LED configurations. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments.

Substitute parts become necessary when the exact ELM 2-125 specification is unavailable, when inventory constraints exist, or when design flexibility permits alternative height specifications within the same product family. The substitute parts listed maintain functional equivalence through shared core parameters: identical LED type (T1), material composition (black PVC), mounting orientation (vertical), lead configuration (2LD), and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 2-125 is determined by strict adherence to the following core parameters:

Non-Negotiable Parameters (Must Match Exactly):

• LED Type: T1
• Material: Black PVC
• Mounting Orientation: Vertical
• Lead Configuration: 2LD
• Color: Black
• Manufacturer: Bivar Inc.
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameter (Allows Substitution):

• Height Specification: 0.125" (3.18mm) is the primary specification, but alternative heights within the ELM series are acceptable when design constraints permit

The two substitute parts listed—ELM 2-120 and ELM 5-130—satisfy all non-negotiable parameters while offering alternative height specifications. The ELM 2-120 provides a reduced height of 0.120" (3.05mm), while the ELM 5-130 provides an increased height of 0.130" (3.30mm). Both maintain identical LED type, material, orientation, lead configuration, color, and compliance certifications as the primary part.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-125 (Primary Specification): Select this part when the exact 0.125" (3.18mm) height is required by design specifications. The part maintains Active product status with established inventory levels and full ROHS3 compliance certification.

ELM 2-120 (Reduced Height Alternative): This substitute is applicable when design constraints permit a 0.005" (0.13mm) reduction in height. The ELM 2-120 remains within the ELM 2 series, maintaining identical base product characteristics. This option provides significantly higher inventory availability (86435 units) compared to the primary part. Selection is appropriate when PCB clearance requirements allow for the reduced height specification.

ELM 5-130 (Increased Height Alternative): This substitute is applicable when design constraints permit a 0.005" (0.12mm) increase in height. The ELM 5-130 transitions to the ELM 5 series while maintaining all core functional parameters. Selection is appropriate when additional standoff height is beneficial for component spacing or thermal management considerations.

All three parts maintain identical compliance certifications (ROHS3), moisture sensitivity ratings (MSL 1), and material specifications (black PVC). Selection between these options depends solely on height requirements within the design specification tolerance.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-120 be used as a direct replacement for ELM 2-125?

A: ELM 2-120 is a functional substitute when the design specification permits a 0.005" (0.13mm) reduction in standoff height. Both parts share identical LED type (T1), material (black PVC), lead configuration (2LD), mounting orientation (vertical), and compliance certifications. Height compatibility must be verified against PCB layout and component clearance requirements.

Q: What is the primary difference between ELM 2-125 and ELM 5-130?

A: The primary difference is the height specification: ELM 2-125 provides 0.125" (3.18mm) height, while ELM 5-130 provides 0.130" (3.30mm) height. Additionally, ELM 5-130 belongs to the ELM 5 series rather than the ELM 2 series. All other parameters—LED type, material, lead configuration, mounting orientation, color, and compliance certifications—remain identical.

Q: Are all three parts ROHS3 compliant?

A: Yes. ELM 2-125, ELM 2-120, and ELM 5-130 are all ROHS3 compliant, meeting current regulatory requirements for production use.

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

A: Moisture Sensitivity Level 1 (Unlimited) indicates that these components have no moisture sensitivity restrictions. They do not require special storage conditions, desiccant packaging, or bake-out procedures prior to assembly.

Q: Can height differences affect PCB assembly?

A: Yes. Height specifications directly impact PCB clearance, component spacing, and potential interference with adjacent components. The 0.005" (0.13mm) difference between ELM 2-125 and ELM 2-120, or between ELM 2-125 and ELM 5-130, must be evaluated against specific PCB layout constraints before substitution.

Q: Which substitute part has the best inventory availability?

A: ELM 2-120 has the highest inventory level at 86435 units in stock, compared to 1126 units for ELM 2-125 and 1461 units for ELM 5-130.

Q: Do all parts use the same packaging format?

A: Yes. ELM 2-125, ELM 2-120, and ELM 5-130 are all supplied in Bag packaging format.
