ELM 7-140 Equivalent & Substitute Parts

Part Overview

The ELM 7-140 is a T1 LED Standoff in black PVC manufactured by Bivar Inc., designed for vertical mounting with a 0.140" (3.56mm) length specification. This component is classified as an active product with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when alternative standoff configurations are required due to design specifications, availability constraints, or application-specific mounting height requirements.

Key Parameters

Substitute Part Grouping Explanation

The ELM 4-145 is identified as a parametric equivalent based on the following substitution criteria:

Matching Parameters (Substitution Basis):

• LED Type: T1
• Material: Black PVC
• Mounting Style: Vertical
• Product Status: Active
• RoHS Compliance: ROHS3
• Moisture Sensitivity Level: 1 (Unlimited)
• Mounting Configuration: Both designed for 2-lead LED standoff applications

Differing Parameters (Critical Design Variable):

• Length: ELM 7-140 measures 0.140" (3.56mm); ELM 4-145 measures 0.145" (3.68mm)
• Series: ELM 7 vs. ELM 4

The 0.005" (0.12mm) difference in length is the controlled variable that permits substitution in applications where standoff height tolerance permits this variation. Both components maintain identical LED accommodation and PVC construction, making them functionally compatible when length specifications allow.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 7-140 and ELM 4-145 maintain active product status with identical RoHS3 compliance and moisture sensitivity ratings. Selection between these parts is determined by the specific standoff length requirement defined in the application design. The ELM 4-145 is available in significantly higher inventory (6639 Pcs vs. 780 Pcs), making it suitable for applications where the 0.005" dimensional variance is within tolerance specifications. Both components are manufactured by Bivar Inc. under identical material and construction standards, ensuring consistent performance characteristics in applications where substitution is mechanically permitted.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 7-140 and ELM 4-145? A: The primary difference is the standoff length: ELM 7-140 is 0.140" (3.56mm) while ELM 4-145 is 0.145" (3.68mm). Both components are manufactured from black PVC and accommodate T1 LED types with identical mechanical interfaces.

Q: Can I substitute ELM 4-145 for ELM 7-140 in my application? A: Substitution is possible only when the application circuit board layout and component clearances accommodate the 0.005" (0.12mm) increase in standoff height. Verify dimensional constraints before substitution.

Q: Are there differences in compliance certifications between these parts? A: No. Both components carry ROHS3 compliance and identical moisture sensitivity ratings, ensuring equivalent environmental and regulatory performance.

Q: What are the key electrical and mechanical parameters that define these standoffs as substitutable? A: The substitutable parameters are: T1 LED type accommodation, black PVC material composition, vertical mounting configuration, and identical lead count (2-lead design). Length is the variable parameter that determines application compatibility.

Q: How should I determine which standoff length is correct for my design? A: Consult your PCB layout documentation for the specified standoff height requirement. This height directly corresponds to the required part length. If your design tolerates the 0.145" dimension, ELM 4-145 is available with greater inventory.
