ERM 1-815

Part Overview

The ERM 1-815 is an LED mounting standoff manufactured by Bivar Inc., designed for 2 and 3 lead LEDs. This component provides vertical mounting capability with a 0.815" (20.70mm) black PVC standoff body. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative equivalent models may be required for application-specific length requirements or inventory optimization.

Key Parameters

Substitute Part Grouping Explanation

The ERM 1-21MM qualifies as a parametric equivalent to the ERM 1-815 based on the following alignment of critical parameters:

Common Parameters:

• Same manufacturer (Bivar Inc.)
• Identical series designation (ERM 1)
• Compatible LED configuration (2 and 3 Lead LEDs)
• Same material composition (Black PVC)
• Identical orientation (Vertical mounting)
• Equivalent product status (Active)
• Identical RoHS compliance (ROHS3 Compliant)
• Identical moisture sensitivity rating (MSL 1 - Unlimited)

Variable Parameter:

• Standoff length: 0.815" (20.70mm) versus 0.830" (21.08mm)

The length variance of 0.015" (0.38mm) between these parts allows substitution in applications where this dimensional tolerance is acceptable for the PCB layout and LED clearance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ERM 1-815 and ERM 1-21MM are active production parts with identical regulatory compliance (ROHS3) and equivalent MSL ratings. Selection between these parts depends solely on PCB layout accommodation of the 0.015" (0.38mm) length difference. Both parts support identical LED configurations and maintain consistent material properties for thermal and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the ERM 1-21MM be used as a direct replacement for the ERM 1-815? A: The ERM 1-21MM differs by 0.015" (0.38mm) in standoff length. Substitution is valid if the assembly design tolerates this dimensional variance without affecting LED clearance, PCB layout, or mechanical constraints.

Q: Are there any material or compliance differences between these parts? A: No. Both parts use identical black PVC material, carry ROHS3 compliance, and maintain the same MSL 1 rating. Manufacturing and regulatory specifications are equivalent.

Q: Do these parts support the same LED lead configurations? A: Yes. Both the ERM 1-815 and ERM 1-21MM accommodate 2 and 3 lead LED components without configuration modifications.

Q: What is the basis for the parametric equivalence? A: Equivalence is established through matching manufacturer, series, LED configuration, material, orientation, product status, and compliance certifications. The standoff length is the only dimensional parameter that differs within acceptable tolerance ranges for many applications.

Q: Are both parts currently available? A: Yes. Both parts maintain active production status with Bivar Inc. Current inventory levels are listed in the product database.
