ELM 7-650 Equivalent & Substitute Parts

Part Overview

The ELM 7-650 is a T1 LED standoff in black PVC with a length of 0.650" (16.51mm), designed for vertical mounting applications with 3MM and 2-lead configurations. This part is currently active in production status and is RoHS3 compliant. Substitute parts are necessary when the primary part number is unavailable or when application requirements permit use of mechanically compatible alternatives with minor dimensional variations within acceptable tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 7-650 is determined by the following parameters: LED type (T1), color (black), material (PVC), mounting configuration (vertical, 3MM, 2-lead), and RoHS3 compliance. The substitute parts ELM 2-665 and ELM 2-17MM meet all critical electrical and mechanical criteria, with dimensional variations in length that fall within acceptable tolerance ranges for applications where the standoff height permits minor deviation. Both substitutes maintain identical LED type, color, material composition, and regulatory compliance status as the main part.

Parameter Comparison

Engineering Selection Recommendations

The ELM 7-650 is the primary specification for applications requiring a 0.650" standoff height. When the ELM 7-650 is unavailable, the ELM 2-665 serves as the closest substitute, with a length of 0.665" (16.89mm), representing a 0.015" dimensional increase. The ELM 2-17MM provides an alternative with a length of 0.670" (17.02mm), representing a 0.020" dimensional increase. Both substitutes are active production items from the same manufacturer with identical RoHS3 compliance and MSL ratings. Selection between substitutes should be based on application mechanical tolerance requirements and design board spacing constraints. All three parts share identical LED type, material composition, and electrical properties.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-665 or ELM 2-17MM be used in place of ELM 7-650? A: Both ELM 2-665 and ELM 2-17MM are parametric equivalents with identical LED type (T1), color (black), material (PVC), and mounting configuration (vertical, 3MM, 2-lead). Substitution is permissible when the application mechanical tolerance accommodates the dimensional variations: ELM 2-665 at 0.665" and ELM 2-17MM at 0.670" compared to the ELM 7-650 at 0.650".

Q: What are the dimensional differences between these parts? A: ELM 7-650 measures 0.650" (16.51mm). ELM 2-665 measures 0.665" (16.89mm), adding 0.015". ELM 2-17MM measures 0.670" (17.02mm), adding 0.020". These differences must be evaluated against board layout and clearance requirements in the target application.

Q: Are all three parts RoHS3 compliant? A: Yes. ELM 7-650, ELM 2-665, and ELM 2-17MM are all RoHS3 compliant with MSL rating 1 (Unlimited).

Q: How do I determine which substitute is appropriate for my application? A: Verify that your application design can accommodate the increased standoff height of the substitute part. ELM 2-665 represents the smallest dimensional deviation from the original specification. Both substitutes are manufactured by Bivar Inc. and are active production items with equivalent electrical and material properties.

Q: Are there packaging differences between these parts? A: All parts are supplied in bag packaging by Bivar Inc. Inventory availability for ELM 7-650 is 1001 pieces, ELM 2-665 is 882 pieces, and ELM 2-17MM is 1815 pieces.
