ELM 7-17MM

Part Overview

The ELM 7-17MM is an active T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.669" (17.00mm) length and 3mm pitch configuration. This component is RoHS3 compliant with MSL Level 1 rating. Substitute parts are necessary when stock availability is limited, when supply chain disruptions occur, or when design flexibility requires equivalent alternatives that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The ELM 7-17MM has two qualified substitute parts: ELM 2-17MM and ELM 2-665. These substitutes are electrically and mechanically equivalent based on the following allowed parameters:

Critical Matching Parameters:

• LED Type: T1 (all parts)
• Material: Black PVC (all parts)
• Configuration: Vertical mounting, 3mm pitch, 2-lead (all parts)
• RoHS Status: RoHS3 Compliant (all parts)
• Moisture Sensitivity Level: 1 (Unlimited) (all parts)
• Product Status: Active (all parts)

Length Tolerance: The three parts operate within a tight tolerance band:

• ELM 7-17MM: 0.669" (17.00mm)
• ELM 2-17MM: 0.670" (17.02mm)
• ELM 2-665: 0.665" (16.89mm)

All three parts fall within acceptable mechanical tolerances for T1 LED standoff applications and are suitable for vertical PCB mounting where lead length permits component insertion and soldering within standard assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ELM 7-17MM, ELM 2-17MM, and ELM 2-665—carry active product status with RoHS3 compliance and MSL Level 1 rating, indicating long-term availability and suitability for standard manufacturing environments. Component selection between these parts should be based on current stock availability and specific PCB hole-to-component lead-length requirements. The marginal length variations (0.665" to 0.670") do not affect electrical performance and fall within standard PCB assembly tolerances for T1 LED standoff insertion and soldering.

Frequently Asked Questions (FAQ)

Q: Are ELM 2-17MM and ELM 2-665 direct drop-in replacements for ELM 7-17MM? A: Yes, both parts are direct substitutes. All three share identical LED type (T1), material (Black PVC), configuration (vertical 3mm pitch 2-lead), and compliance certifications. Length variations of ±0.005" fall within acceptable tolerances for T1 LED standoff mounting.

Q: Does the length difference between 17.00mm, 17.02mm, and 16.89mm affect circuit performance? A: No. The length variance is a mechanical parameter that affects only physical standoff height. Electrical performance and LED characteristics remain identical across all three parts.

Q: What is the difference between ELM 7 and ELM 2 series designations? A: Series designation indicates manufacturer product line classification. Both ELM 7 and ELM 2 series contain equivalent T1 LED standoffs that meet identical electrical and mechanical specifications for this application class.

Q: Are all three parts RoHS3 compliant and MSL Level 1? A: Yes. ELM 7-17MM, ELM 2-17MM, and ELM 2-665 are all RoHS3 compliant with MSL Level 1 (Unlimited) rating, ensuring compatibility with standard assembly and storage conditions.

Q: Which substitute part should I select if multiple options are available? A: Selection should be based on current inventory availability and specific design requirements. If the exact 17.00mm length is preferred, ELM 2-17MM at 17.02mm provides the closest match. For applications where ±0.005" tolerance is acceptable, ELM 2-665 at 16.89mm is equally suitable.
