ELM 3-790 Equivalent & Substitute Parts

Part Overview

The ELM 3-790 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.790" (20.07mm) length. This component is constructed from black PVC material and is classified as an active product with ROHS3 compliance. LED standoffs serve as mechanical and electrical interfaces for LED component positioning in circuit assemblies. Substitute parts are identified when equivalent functional performance can be achieved within the allowed parameter tolerances for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 3-790 is determined by the following critical parameters:

Mandatory Matching Parameters:

• LED Type: T1 3/4 (physical form factor compatibility)
• Material: Black PVC (electrical and mechanical properties)
• Mounting Style: Vertical (assembly orientation)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• MSL Rating: 1 (Unlimited) (environmental tolerance)

Allowable Variation Parameter:

• Length: Within tolerance range for mechanical fit in target application

The ELM 1-820 is identified as a parametric equivalent because it maintains all mandatory matching parameters while presenting a length variation of 0.030" (0.76mm) from the main part specification.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 3-790 and ELM 1-820 are active products manufactured by Bivar Inc. with ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts is based on mechanical fit requirements within the target assembly.

The ELM 3-790 is the primary specification when the 0.790" (20.07mm) length is a design requirement. The ELM 1-820 provides an alternative with a 0.030" (0.76mm) longer standoff height. Both parts maintain identical electrical and environmental compliance characteristics.

Inventory availability: ELM 3-790 has 679 pieces in stock; ELM 1-820 has 1983 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-820 be used as a direct replacement for ELM 3-790?

A: ELM 1-820 is a parametric equivalent with all mandatory electrical and material specifications matching ELM 3-790. The length difference of 0.030" (0.76mm) must be evaluated against the mechanical constraints of the target application. If the assembly design accommodates this height variance, substitution is permissible.

Q: What are the critical parameters that must match for substitution?

A: LED type (T1 3/4), material (Black PVC), mounting style (Vertical), RoHS compliance (ROHS3), and MSL rating (1 - Unlimited) must remain constant. Length is the only parameter with allowable variation.

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

A: Yes, both ELM 3-790 and ELM 1-820 are supplied in bag packaging.

Q: Do both parts meet the same environmental compliance standards?

A: Yes, both parts are ROHS3 compliant with MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: What is the length difference between these parts?

A: ELM 1-820 is 0.030" (0.76mm) longer than ELM 3-790. The main part measures 0.790" (20.07mm); the substitute measures 0.820" (20.83mm).
