ELM 7-655 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 7-655 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.655" (16.64mm) length. This component is an active product in production status, constructed from black PVC material with a 3mm LED configuration and 2-lead design. The ELM 7-655 maintains ROHS3 compliance and carries an MSL rating of 1 (Unlimited), indicating minimal moisture sensitivity for storage and handling.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility permits selection from equivalent alternatives within the same product family. The substitute parts listed maintain functional and mechanical compatibility through matching core parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 7-655 is determined by the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 (must match exactly)
• Material: Black PVC (must match exactly)
• Lead Configuration: 2-Lead (must match exactly)
• Mounting Orientation: Vertical (must match exactly)
• RoHS Compliance: ROHS3 Compliant (must match or exceed)
• Moisture Sensitivity Level: 1 (Unlimited) (must match or be more favorable)

Secondary Consideration:

• Length tolerance: Substitute parts must fall within the mechanical envelope constraints of the application. The ELM 7-655 operates at 0.655" (16.64mm); substitute parts with lengths of 0.665" (16.89mm) or 0.670" (17.02mm) represent minor dimensional variations acceptable for equivalent substitution.

Both identified substitute parts—ELM 2-665 and ELM 2-17MM—satisfy all primary criteria and represent parametric equivalents within the Bivar Inc. ELM product family.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-665 Selection Criteria: The ELM 2-665 represents the closest dimensional equivalent to the ELM 7-655, with a length differential of 0.010" (0.25mm). This substitute maintains identical material composition, LED type, lead configuration, and compliance certifications. The ELM 2-665 is an active product with confirmed inventory availability of 882 pieces. Selection of this substitute is appropriate when dimensional tolerance permits the minimal length increase and when supply of the primary part is constrained.

ELM 2-17MM Selection Criteria: The ELM 2-17MM provides an alternative with a length of 0.670" (17.02mm), representing a 0.015" (0.38mm) increase over the ELM 7-655. This substitute maintains all core functional parameters and compliance requirements. The ELM 2-17MM carries higher inventory availability at 1815 pieces. Selection of this substitute is appropriate for applications where the additional length falls within mechanical envelope constraints and where extended supply availability is prioritized.

Compliance Verification: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) ratings, ensuring compatibility with standard manufacturing and storage protocols. All parts are classified as active products, confirming ongoing manufacturer support and availability.

Frequently Asked Questions (FAQ)

Q: What determines whether ELM 2-665 or ELM 2-17MM can substitute for ELM 7-655?

A: Substitution is determined by matching LED type (T1), material (Black PVC), lead configuration (2-Lead), mounting orientation (Vertical), and compliance status (ROHS3 Compliant, MSL 1). Length variations of 0.010" to 0.015" are acceptable provided the application mechanical envelope permits the dimensional increase.

Q: Are there any performance differences between the ELM 7-655 and its substitutes?

A: No performance differences exist. All three parts share identical LED type, material composition, lead configuration, and electrical characteristics. Differences are limited to length dimensions within the ELM product family.

Q: Can I use ELM 2-17MM in place of ELM 7-655 without design modification?

A: Substitution requires verification that the application mechanical envelope accommodates the 0.015" (0.38mm) length increase. No electrical or functional modifications are required.

Q: What is the inventory status of substitute parts?

A: ELM 2-665 maintains 882 pieces in stock. ELM 2-17MM maintains 1815 pieces in stock. Both are active products with confirmed availability.

Q: Do all parts carry the same compliance certifications?

A: Yes. ELM 7-655, ELM 2-665, and ELM 2-17MM all carry ROHS3 compliance and MSL 1 (Unlimited) ratings. All are active products in production status.

Q: What is the packaging format for these parts?

A: All three parts are supplied in bag packaging, consistent with standard component distribution for LED standoff assemblies.
