ERM 1-820 Equivalent & Substitute Parts

Part Overview

The ERM 1-820 is an LED Standoff component manufactured by Bivar Inc., designed for 2 and 3 Lead LEDs. This component features a black PVC construction with a height of 0.820" (20.83mm) and supports universal LED applications. The product maintains Active status and is RoHS3 compliant. Alternative parts become necessary when the specified height dimension is unavailable or when inventory constraints require sourcing from equivalent specifications.

Key Parameters

Substitute Part Grouping Explanation

The ERM 1-21MM is identified as a parametric equivalent to the ERM 1-820 based on the following allowed substitution parameters:

• Manufacturer: Both parts are manufactured by Bivar Inc.
• Series: Both parts belong to the ERM 1 product series
• LED Compatibility: Both support 2 and 3 Lead LEDs
• Material: Both feature black PVC construction
• Compliance Standards: Both maintain RoHS3 compliance and identical MSL rating
• Packaging: Identical bag packaging format
• Trade Classifications: Both share identical ECCN and HTSUS codes

The substitution is valid within applications tolerating a height variation of 0.010" (0.25mm), as the ERM 1-21MM measures 0.830" (21.08mm) compared to the 0.820" (20.83mm) specification of the primary part.

Parameter Comparison

Engineering Selection Recommendations

Both the ERM 1-820 and ERM 1-21MM maintain identical active product status with full RoHS3 compliance and MSL rating of 1. The selection between these parts is determined by height dimensional requirements. The ERM 1-820 is specified for applications requiring a 0.820" (20.83mm) standoff height, while the ERM 1-21MM accommodates 0.830" (21.08mm) height specifications. Component selection should prioritize the exact dimensional requirement of the target application.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the ERM 1-820 and ERM 1-21MM?

A: The principal difference is the standoff height. The ERM 1-820 measures 0.820" (20.83mm), while the ERM 1-21MM measures 0.830" (21.08mm), a differential of 0.010" (0.25mm).

Q: Are both parts compatible with the same LED types?

A: Yes. Both the ERM 1-820 and ERM 1-21MM support 2 and 3 Lead LEDs, providing identical LED accommodation capabilities.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are RoHS3 compliant with an MSL rating of 1 (Unlimited), identical ECCN classification (EAR99), and matching HTSUS codes (3926.90.9985).

Q: Can the ERM 1-21MM be used as a direct replacement for the ERM 1-820?

A: Substitution is valid only when the application tolerates a height increase of 0.010" (0.25mm). Applications with strict dimensional constraints require the specified part number.

Q: Are both parts supplied in the same packaging format?

A: Yes. Both parts are supplied in bag packaging, providing identical handling and storage specifications.

Q: What should determine the choice between these two parts?

A: The selection is driven by the required standoff height for your specific application. Verify your PCB or assembly specification for the exact dimensional requirement before component selection.
