ELM 5-645 Equivalent & Substitute Parts

Part Overview

The ELM 5-645 is a T1 LED standoff holder manufactured by Bivar Inc., featuring a black PVC construction with a 0.645" (16.38mm) length. This component is classified as an active product and serves as a mechanical mounting solution for T1 LED packages in vertical surface-mount applications. Alternative models become necessary when specific length tolerances, inventory constraints, or series compatibility requirements necessitate selection from equivalent designs within the manufacturer's product portfolio.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELM 5-645 is governed by the following parameters: LED type designation (T1), material composition (PVC), color (black), and length tolerance. The substitute parts ELM 2-665 and ELM 2-17MM share the identical LED type, material, and color specification. Dimensional variance in length (0.645", 0.665", and 0.670") represents the primary parametric distinction between the main part and its substitutes. All substitute parts maintain equivalent RoHS3 compliance and MSL rating, ensuring compatibility within regulatory and environmental sensitivity requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ELM 5-645, ELM 2-665, and ELM 2-17MM—maintain active product status and ROHS3 compliance. Selection among these parts is determined by required length specification and series compatibility. The ELM 5-645 represents the nominal design at 0.645" length. The ELM 2-665 offers a 0.020" (0.51mm) increase in length, while the ELM 2-17MM provides the maximum length at 0.670". Each part is suitable for equivalent mechanical mounting applications where T1 LED vertical positioning requirements align with the respective length tolerance.

Frequently Asked Questions (FAQ)

Q: Can I substitute ELM 2-665 or ELM 2-17MM for ELM 5-645 in my design?

A: Substitution is valid only if the application accommodates the dimensional difference in standoff length. ELM 2-665 is 0.020" (0.51mm) longer than the ELM 5-645, and ELM 2-17MM is 0.025" (0.64mm) longer. Verify that the PCB layout and LED placement tolerances permit this variation.

Q: Are there compliance or environmental differences among these parts?

A: No. All three parts share identical RoHS3 compliance status and MSL rating of 1 (Unlimited), indicating equivalent regulatory status and unlimited shelf-life storage conditions.

Q: Why are there multiple series designations (ELM 5 vs. ELM 2)?

A: Series designation reflects the base product family within Bivar Inc.'s product line. Both series maintain identical mechanical and electrical characteristics for T1 LED mounting applications. Selection between series is determined by length specification rather than functional differences.

Q: What is the critical parameter for substitution compatibility?

A: LED type (T1), material (PVC), and color (black) must remain unchanged. Length variation is the primary parameter permitting substitution, provided the application mechanical constraints accommodate the dimensional difference.

Q: Are packaging considerations different between these parts?

A: All parts are supplied in bag packaging. Consult inventory status and lead time availability for procurement planning, though packaging format remains consistent across the three options.
