Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 2-685 are determined by equivalence in the following critical parameters: LED type (T1), material composition (black PVC), mounting orientation (vertical), and lead configuration (3MM, 2-lead). The ELM 2 series maintains consistent functional compatibility across variants that share these electrical and mechanical attributes. Substitution is valid when parts maintain identical LED specifications, mounting characteristics, and material properties, with minor dimensional tolerances in height between 0.665" and 0.685" remaining functionally equivalent within standard PCB design constraints.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, meeting environmental regulatory requirements. Selection between ELM 2-685, ELM 2-17MM, and ELM 2-665 is based on specific height requirements dictated by circuit board design specifications. The ELM 2-665 represents the shortest option at 0.665" (16.89mm), the ELM 2-17MM provides an intermediate height at 0.670" (17.02mm), and the ELM 2-685 offers the maximum height at 0.685" (17.40mm). All parts share identical LED type, material, lead configuration, and compliance certifications, supporting direct substitution when dimensional requirements align with the selected standoff height.

Frequently Asked Questions (FAQ)

Q: Can the ELM 2-665 be used as a direct replacement for the ELM 2-685? A: The ELM 2-665 provides parametric equivalence in LED type, material, lead configuration, and electrical properties. The height difference of 0.020" (0.51mm) must be evaluated against the specific PCB clearance and component spacing requirements of the intended application.

Q: What are the primary compatibility criteria between these substitute parts? A: Compatibility is determined by T1 LED type specification, black PVC material composition, 3MM and 2-lead configuration, and mounting orientation. Parts within the ELM 2 series meeting these parameters are considered functionally equivalent.

Q: Are all three parts compliant with current environmental standards? A: All three parts—ELM 2-685, ELM 2-17MM, and ELM 2-665—carry ROHS3 compliance and MSL 1 (Unlimited) ratings, meeting current environmental and moisture sensitivity requirements.

Q: What is the primary difference between these equivalent parts? A: The primary difference is standoff height: ELM 2-685 at 0.685" (17.40mm), ELM 2-17MM at 0.670" (17.02mm), and ELM 2-665 at 0.665" (16.89mm). All other electrical and mechanical properties remain consistent across the series.

Q: How should I select between the available substitutes? A: Selection is determined by the height clearance required in your specific application design. Verify PCB stackup and component spacing to identify which height variant best accommodates your manufacturing and assembly requirements.
