Key Parameters

Substitute Part Grouping Explanation

The ELM 3-545 has one parametric equivalent: ELM 1-545. Substitution eligibility is determined by strict alignment across the following critical parameters:

• LED Type: T1 3/4 (mandatory match)
• Length: 0.545" (13.84mm) (mandatory match)
• Color: Black (mandatory match)
• Material: PVC (mandatory match)
• RoHS Compliance: ROHS3 Compliant (mandatory match)
• Moisture Sensitivity Level: 1 (Unlimited) (mandatory match)

The ELM 1-545 satisfies all substitution criteria, differing only in series designation (ELM 1 versus ELM 3) and base product number. Both parts maintain identical physical and electrical characteristics for LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 3-545 and ELM 1-545 carry Active product status with ROHS3 compliance and MSL 1 (Unlimited) certification. Selection between these parts should be based on inventory availability and procurement lead times. The ELM 1-545 currently maintains higher inventory levels (20,121 pieces) compared to the ELM 3-545 (779 pieces), making it a viable alternative for applications requiring expedited sourcing without design modification.

Frequently Asked Questions (FAQ)

Q: Are the ELM 3-545 and ELM 1-545 mechanically interchangeable? A: Yes. Both parts share identical LED type (T1 3/4), length (0.545"/13.84mm), color (Black), and material (PVC) specifications, ensuring mechanical compatibility in standard LED standoff applications.

Q: What differences exist between the ELM 3-545 and ELM 1-545? A: The parts differ only in their series designation (ELM 3 versus ELM 1) and base product number. All functional and physical parameters remain identical.

Q: Can I use ELM 1-545 as a direct replacement for ELM 3-545? A: Yes, provided your application requires T1 3/4 LED standoffs with 0.545" length, black PVC construction, and compliance with ROHS3 and MSL 1 specifications.

Q: Are both parts RoHS compliant? A: Yes. Both the ELM 3-545 and ELM 1-545 are ROHS3 compliant and rated at Moisture Sensitivity Level 1 (Unlimited).

Q: Which part should I select based on availability? A: The ELM 1-545 offers superior inventory availability (20,121 pieces) compared to the ELM 3-545 (779 pieces) for applications where inventory access is a procurement consideration.
