ELM 3-125

Part Overview

The ELM 3-125 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications requiring a 0.125" (3.18mm) height dimension. This component is constructed from black PVC material and accommodates standard T1 3/4 LED packages. The part maintains Active product status and full ROHS3 compliance, making it suitable for current production environments. Alternative models may be necessary when dimensional constraints require a slightly reduced standoff height or when inventory levels for the primary part are insufficient.

Key Parameters

Substitute Part Grouping Explanation

The ELM 1-3MM qualifies as a parametric equivalent based on the following key substitution criteria:

• LED Package Compatibility: Both parts accommodate T1 3/4 LED packages, ensuring physical and electrical compatibility with standard LED component footprints.
• Material and Color: Both utilize black PVC construction, maintaining mechanical and aesthetic consistency.
• Mounting Orientation: Both are configured for vertical mounting orientation.
• Regulatory Compliance: Both parts meet ROHS3 compliance requirements and carry MSL 1 ratings.

The primary distinction between these parts is the length dimension: the ELM 3-125 provides 0.125" (3.18mm) height, while the ELM 1-3MM provides 0.120" (3.05mm) height. This 0.005" (0.13mm) difference represents a 4% reduction in standoff height and should be evaluated against specific mechanical clearance requirements in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both ELM 3-125 and ELM 1-3MM maintain Active product status within the Bivar Inc. portfolio and carry identical ROHS3 compliance certifications. Either part may be selected based on application-specific dimensional requirements. The ELM 1-3MM presents increased inventory availability (6024 units vs. 1073 units), which may provide supply chain advantages. Selection should be determined by mechanical clearance constraints and assembly requirements relative to the 0.005" height differential.

Frequently Asked Questions (FAQ)

Q: Can the ELM 1-3MM replace the ELM 3-125 in my application? A: Direct substitution is possible if your circuit design accommodates the reduced 0.120" standoff height. The 0.005" difference must be evaluated against mechanical clearance and alignment requirements specific to your PCB layout and assembly process.

Q: Are both parts manufactured from identical materials? A: Both the ELM 3-125 and ELM 1-3MM are constructed from black PVC, ensuring material consistency between the primary part and its substitute.

Q: Do both parts support the same LED package types? A: Yes, both parts are designed to accommodate T1 3/4 LED packages, providing identical LED compatibility.

Q: What is the significance of the MSL 1 rating? A: An MSL 1 rating indicates unlimited moisture sensitivity, meaning the parts require no special moisture control measures during storage, handling, or assembly.

Q: Which part should I select if both are compatible with my application? A: Selection should be based on your specific mechanical constraints and the required standoff height. The ELM 1-3MM offers higher inventory availability, which may reduce procurement lead times. Verify that the 0.120" height does not conflict with your PCB design clearances.

Q: Do both parts carry identical compliance certifications? A: Both parts are ROHS3 compliant with identical MSL 1 ratings, meeting equivalent regulatory requirements for current production environments.
