Parameter Comparison

Engineering Selection Recommendations

The 5520233F from Dialight is the identified substitute for the obsolete 5670H7LC_7LC. Selection is based on the following engineering criteria:

Mechanical Fit: The 5520233F maintains identical physical dimensions, lens geometry, and mounting configuration, ensuring direct board-level compatibility without PCB redesign.

Regulatory Compliance: Both components are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting environmental and moisture sensitivity requirements.

Product Availability: The 5520233F is in active production status with confirmed inventory, whereas the original part is obsolete and subject to supply discontinuation.

Electrical Differences: The substitute operates at 2.1V forward voltage (versus 1.9V) and 10mA current rating (versus 7mA). Circuit designs must accommodate these higher electrical ratings through appropriate current-limiting resistor selection and voltage supply verification.

Optical Performance: The 5520233F provides 6.3mcd luminous intensity compared to 2.1mcd in the original part. This increased brightness is suitable for indicator applications and does not create compatibility issues in diffused lens designs.

Frequently Asked Questions (FAQ)

Q: Can the 5520233F be used as a direct drop-in replacement for the 5670H7LC_7LC?

A: The 5520233F is mechanically and optically compatible for board-level installation. However, circuit electrical parameters must be verified. The substitute requires higher forward voltage (2.1V vs. 1.9V) and higher current rating (10mA vs. 7mA). Existing current-limiting resistors must be recalculated to accommodate these differences.

Q: What are the key mechanical compatibility factors?

A: Both components share identical lens size (5mm, T-1 3/4), lens style (round with domed top), mounting type (through-hole right angle), and configuration (2 high). PCB footprints and mounting hole spacing are compatible without modification.

Q: Are there optical differences between the two parts?

A: Both components are yellow (x 2) bi-level indicators with diffused, tinted lenses. Peak wavelengths differ slightly (583nm vs. 585nm), both within the yellow spectrum. The 5520233F provides higher luminous intensity (6.3mcd vs. 2.1mcd), resulting in brighter indicator operation.

Q: What compliance certifications apply to the substitute part?

A: The 5520233F is ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original part's regulatory status. REACH status is listed as unaffected.

Q: How should circuit design be modified for the substitute part?

A: Forward voltage and current ratings differ. Recalculate current-limiting resistor values based on the 2.1V forward voltage and 10mA maximum current rating of the 5520233F. Verify that the circuit power supply can accommodate the higher voltage drop.

Q: Is the substitute part available in the same packaging?

A: The 5520233F is supplied in bulk packaging, whereas original packaging information for the 5670H7LC_7LC was not specified. Confirm packaging requirements for your procurement process.

Q: What is the inventory status of the substitute part?

A: The 5520233F has confirmed inventory of 1421 pieces in new original stock condition, ensuring supply availability for production and maintenance applications.
