Frequently Asked Questions (FAQ)

Q: Can the L2C5-40701211E1900 be used as a direct replacement for the LHC1-4070-1211?

A: Yes. Both parts share identical mechanical dimensions (28mm x 28mm x 1.50mm), electrical operating parameters (2.4A maximum current, 1.2A test current), optical characteristics (115° viewing angle, flat lens), and packaging format (tube). All mounting, thermal, and electrical interfaces are compatible.

Q: What are the key differences between these two parts?

A: The L2C5-40701211E1900 represents a newer generation (LUXEON CoB Core Range Gen 3) with improved luminous efficacy. At identical test conditions (1.2A, 85°C), the substitute delivers 6726 lumens versus 5600 lumens for the original part, corresponding to 161 lm/W versus 131 lm/W. Forward voltage is slightly lower (34.8V versus 35.5V). Color temperature tolerance is specified as 3-Step MacAdam Ellipse for the substitute.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance, REACH Unaffected status, MSL 1 (Unlimited) rating, and EAR99 ECCN classification. Regulatory requirements for either part are equivalent.

Q: What is the packaging format for both parts?

A: Both the LHC1-4070-1211 and L2C5-40701211E1900 are supplied in tube packaging, maintaining consistent handling and storage requirements.

Q: Why is the original part classified as obsolete?

A: The LHC1-4070-1211 has been superseded by the L2C5-40701211E1900 within Lumileds' product portfolio. The substitute part offers improved performance metrics while maintaining full backward compatibility, making it the active alternative for new designs and production continuity.
