ELM 5-125 Equivalent & Substitute Parts

Part Overview

The ELM 5-125 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.125" (3.18mm) height. This component is a black PVC standoff intended for use with 3mm LED assemblies in two-lead configurations. The part is currently active in production with full inventory availability. Substitute parts are identified when equivalent functional performance is required due to design modifications, inventory constraints, or application-specific dimensional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 5-125 is determined by the following critical parameters:

Mandatory Matching Parameters:

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

Variable Parameter:

• Length: 0.125" (3.18mm) for the main part; substitute parts vary within the ELM series with lengths of 0.120" (3.05mm) and 0.130" (3.30mm)

The ELM 5-130 and ELM 2-120 are identified as parametric equivalents because they maintain all mandatory matching parameters while offering alternative height specifications. These substitutes are suitable for applications where dimensional tolerance or PCB standoff height requirements differ from the primary specification.

Parameter Comparison

Engineering Selection Recommendations

ELM 5-130 Selection Criteria: The ELM 5-130 is a direct series equivalent with a 0.005" (0.12mm) greater height than the ELM 5-125. Both parts share the same base product number (ELM 5-1) and series designation. Selection of the ELM 5-130 is appropriate when PCB layout requires increased standoff height while maintaining identical mechanical and electrical characteristics. This part carries identical compliance certifications (ROHS3, MSL 1).

ELM 2-120 Selection Criteria: The ELM 2-120 is a parametric equivalent from the ELM 2 series with a 0.005" (0.13mm) reduced height compared to the ELM 5-125. This part maintains all functional parameters required for T1 LED standoff applications. Selection of the ELM 2-120 is appropriate when reduced standoff height is required or when ELM 5 series inventory is unavailable. This part carries identical compliance certifications (ROHS3, MSL 1) and is REACH Unaffected.

Both substitute parts are active production items with confirmed inventory availability and full regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the ELM 5-130 be used in place of the ELM 5-125 without design modification?

A: The ELM 5-130 differs only in length (0.130" versus 0.125"). Substitution is permissible only if the application tolerates the additional 0.005" (0.12mm) height. PCB layout, component clearance, and mechanical assembly requirements must be evaluated for compatibility.

Q: What is the primary difference between the ELM 5-130 and ELM 2-120?

A: Both parts are functionally equivalent T1 LED standoffs with identical material, color, and lead configuration. The ELM 5-130 belongs to the ELM 5 series with 0.130" height, while the ELM 2-120 belongs to the ELM 2 series with 0.120" height. Series designation reflects manufacturing lineage; functional performance is equivalent.

Q: Are all three parts RoHS compliant?

A: Yes. The ELM 5-125, ELM 5-130, and ELM 2-120 are all ROHS3 compliant. The ELM 2-120 additionally carries REACH Unaffected status.

Q: What is the moisture sensitivity level for these parts?

A: All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly.

Q: Can these parts be used interchangeably in high-volume production?

A: Interchangeability is limited to applications where the specific height dimension is not a critical design parameter. Production changeover between parts requires verification that PCB layout, component spacing, and mechanical tolerances accommodate the dimensional variation (0.120" to 0.130" range).

Q: What packaging format is used for these parts?

A: All three parts are supplied in bag packaging, suitable for bulk component handling and automated assembly processes.
