ERM 1-810 Equivalent and Substitute Parts

Part Overview

The ERM 1-810 is an active, ROHS3-compliant LED standoff manufactured by Bivar Inc., designed for mounting 2 and 3 lead LEDs in vertical orientation. This black PVC standoff features a 0.810" (20.57mm) length and serves as a universal mounting solution for LED assemblies. The availability of substitute parts with comparable specifications ensures design flexibility and supply chain continuity when the primary part is unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERM 1-810 is permissible based on the following criteria that define functional equivalence within the ERM 1 series:

Allowed Variation Parameters:

• Length tolerance: Standoff length may vary within the universal mounting envelope (0.810" nominal)
• Manufacturer: Must remain Bivar Inc. (series-specific qualification)
• Series designation: ERM 1 series compatibility
• Material composition: PVC construction
• Color: Black
• LED configuration support: 2 and 3 lead LED compatibility
• Compliance certifications: ROHS3 Compliant, MSL 1

The ERM 1-21MM is a qualified parametric equivalent due to its identical material, color, LED configuration support, compliance status, and series designation. The length variance (0.830" versus 0.810") falls within the universal mounting specification for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the ERM 1-810 and ERM 1-21MM are active, production-status components with identical ROHS3 compliance and MSL 1 ratings. Selection between these parts is determined by mechanical fit requirements within the assembly envelope, specifically the length specification of 0.810" versus 0.830".

The ERM 1-810 is the primary selection for designs requiring the nominal 0.810" (20.57mm) length. The ERM 1-21MM serves as a direct functional substitute where the 0.830" (21.08mm) length is acceptable within the PCB standoff clearance and LED assembly geometry specifications.

Frequently Asked Questions (FAQ)

Q: Can the ERM 1-21MM be used in place of the ERM 1-810? A: The ERM 1-21MM is a parametric equivalent with identical material, color, LED support configuration, and compliance certifications. Substitution is permissible when the increased length of 0.830" (21.08mm) versus 0.810" (20.57mm) does not conflict with the assembly mechanical constraints.

Q: What determines whether these parts are substitutable? A: Substitutability is governed by PVC material composition, black color specification, 2 and 3 lead LED configuration support, vertical orientation, ROHS3 compliance, and MSL 1 rating. Both parts maintain these parameters.

Q: Does packaging affect part selection? A: Both parts are supplied in bag packaging. Packaging format does not affect functional or mechanical compatibility.

Q: Are there any compliance differences between the ERM 1-810 and ERM 1-21MM? A: No. Both parts share identical RoHS compliance (ROHS3) and moisture sensitivity level (MSL 1), and both carry the same ECCN and HTSUS classifications, ensuring equivalent regulatory compliance for component selection.

Q: What is the primary consideration for substitution between these ERM 1 series parts? A: The primary mechanical variable is standoff length. Design review of PCB-to-LED assembly clearance is necessary to confirm that the 0.020" (0.51mm) length difference is accommodated within the application.
