ELM 7-520 Equivalent & Substitute Parts

Part Overview

The ELM 7-520 is an active T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.520" (13.21mm) length. This component is designed for vertical LED mounting applications with 3mm spacing and 2-lead configuration. The part is ROHS3 compliant and carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. This part is included in this reference due to availability of parametric equivalents that maintain core functional specifications while accommodating variations in mounting height requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 7-520 are classified as parametric equivalents based on the following criteria:

Critical Parameters for Substitution:

• LED Type: T1 (must remain constant)
• Material: Black PVC (must remain constant)
• Configuration: Vertical Mount, 3MM, 2-Lead (must remain constant)
• Regulatory Compliance: ROHS3 Compliant (must remain constant)
• Moisture Sensitivity Level: 1 (Unlimited) (must remain constant)

Variable Parameter:

• Length: Allowable variations in mounting height (0.500", 0.510", 0.520")

The substitute parts ELM 2-510 and ELM 2-500 maintain all critical parameters while providing alternative mounting heights. These variations allow for application flexibility when height clearance or circuit board layout requires adjustment.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ELM 7-520, ELM 2-510, and ELM 2-500—are active products from Bivar Inc. with ROHS3 compliance and MSL 1 ratings. Selection between these parts should be based on circuit board clearance and mounting height requirements. The ELM 7-520 provides maximum height at 0.520" (13.21mm), while the ELM 2-510 and ELM 2-500 provide reduced heights of 0.510" (12.95mm) and 0.500" (12.70mm) respectively. All variants maintain identical electrical and mechanical specifications for LED type, lead configuration, and material composition.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-510 or ELM 2-500 be used in place of ELM 7-520? A: Yes, when circuit board layout and clearance requirements permit. The primary difference is mounting height. ELM 2-510 differs by 0.010" (0.26mm) and ELM 2-500 differs by 0.020" (0.51mm) in length from the ELM 7-520.

Q: Are there electrical differences between these parts? A: No. All parts share identical LED type (T1), lead configuration (2-Lead, 3MM spacing), and material specification (Black PVC). Differences are purely mechanical in mounting height.

Q: Do all parts meet the same compliance requirements? A: Yes. All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings and carry EAR99 export classification.

Q: What determines which substitute part to select? A: Available mounting height on the circuit board. Select the part whose length best accommodates your specific application's height constraints while maintaining the required clearance above the PCB surface.

Q: Are there packaging or lead form differences? A: No. All parts are supplied in bag packaging with identical 2-lead vertical mount configuration and 3MM spacing.
