ELM 7-125 Equivalent & Substitute Parts Reference

Part Overview

The ELM 7-125 is a T1 LED standoff in black PVC material with a 0.125" (3.18mm) height, manufactured by Bivar Inc. This component is designed for vertical mounting of T1 LEDs in applications requiring precise standoff positioning. The product maintains Active status and full RoHS3 compliance. Alternative models may be required when specific height requirements differ from the standard 0.125" dimension or when inventory constraints necessitate substitution with parametrically equivalent units.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 7-125 are qualified based on the following criteria:

Common Parameters (Substitution Basis):

• LED Type: T1 (standard T1 LED form factor)
• Material: Black PVC (identical material composition)
• Mounting Configuration: Vertical (same mounting orientation)
• Manufacturer: Bivar Inc. (same manufacturer, ensuring design consistency)
• RoHS Status: ROHS3 Compliant (equivalent regulatory compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (identical environmental rating)

Variable Parameter (Determines Substitutability):

• Height: Ranges from 0.120" (3.05mm) to 0.130" (3.30mm)

The ELM 2-120 and ELM 5-130 represent parametric equivalents that differ only in standoff height from the primary reference part. These dimensions accommodate applications with varying PCB-to-LED clearance requirements while maintaining all other mechanical and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status with ROHS3 compliance and identical Moisture Sensitivity Level ratings, ensuring consistent performance across regulatory and environmental requirements. Selection between ELM 7-125, ELM 2-120, and ELM 5-130 depends solely on the mechanical height requirement for your application. The ELM 2-120 provides the minimum height option at 0.120" (3.05mm), suitable for designs with tight vertical clearance constraints. The ELM 7-125 at 0.125" (3.18mm) represents the reference dimension. The ELM 5-130 at 0.130" (3.30mm) accommodates applications requiring maximum standoff height within this family. All parts share identical compliance certifications and supply chain status.

Frequently Asked Questions (FAQ)

Q: Can I use ELM 2-120 as a direct replacement for ELM 7-125 in my assembly?

A: Substitution is possible if your PCB design accommodates a 0.005" (0.127mm) reduction in LED standoff height. Verify that the lower LED position does not interfere with surrounding components or optical requirements.

Q: What is the maximum height difference between substitute parts?

A: The ELM 5-130 is 0.005" (0.127mm) taller than the ELM 7-125, while the ELM 2-120 is 0.005" (0.127mm) shorter. Total variation across the family spans 0.010" (0.254mm).

Q: Do all three parts have the same RoHS compliance status?

A: Yes, all parts (ELM 7-125, ELM 2-120, and ELM 5-130) are ROHS3 compliant with identical Moisture Sensitivity Level ratings of 1 (Unlimited).

Q: Which part should I select if exact dimensional matching is critical?

A: Use the original ELM 7-125 specification. The substitute parts are engineered for applications where the height tolerance permits a ±0.005" variance.

Q: Are these parts available from the same manufacturer?

A: All three parts are manufactured by Bivar Inc., ensuring consistent design heritage and manufacturing process control across the product family.
