Engineering Selection Recommendations

Brightness-Matched Substitutes (High Brightness Applications):

For applications requiring brightness levels comparable to the MV8190's 100mcd rating, the Würth Elektronik 151051RS11000 (30mcd) and Dialight 5219672F (60mcd) provide the closest alternatives. The 151051RS11000 operates at 2.1V forward voltage with 20mA test current and 60° viewing angle. The 5219672F operates at 2V forward voltage with 20mA test current and 60° viewing angle. Both are active products with ROHS3 compliance.

Low-Brightness Substitutes (Indicator Applications):

For applications where lower brightness is acceptable, the Broadcom Limited HLMP-3301 series offers multiple packaging options with active product status and ROHS3 compliance. The HLMP-3301 (5.4mcd) and HLMP-3301-D0000 (2.1mcd) variants operate at 1.9V forward voltage with 10mA test current and 60° viewing angle. The HLMP-3301-D0002 and HLMP-3301-F0002 variants provide the same electrical specifications in Cut Tape and Cut Tape packaging respectively, with 6900 and 6700 units in stock.

Voltage Compatibility:

All substitute parts operate within 1.7V to 2.1V forward voltage range. Circuit designs using current-limiting resistors will accommodate this variation. The MV8190's 1.7V specification is the lowest in the substitute group; designs originally specified for 1.7V may require resistor adjustment when using 1.9V or 2.1V substitutes.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance and REACH Unaffected status. All substitute parts are classified as active products with current inventory availability, ensuring long-term procurement viability compared to the obsolete MV8190.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MV8190 with any of these substitute parts without circuit modification?

A: Direct replacement is possible for most applications due to compatible through-hole radial package and similar forward voltage range (1.7V to 2.1V). However, brightness differences require evaluation. The MV8190 operates at 100mcd; substitute parts range from 2.1mcd to 60mcd. Applications sensitive to brightness levels may require circuit adjustment or selection of higher-brightness alternatives like the 5219672F (60mcd).

Q: What is the primary difference between HLMP-3301 variants?

A: HLMP-3301 variants differ in packaging format and millicandela rating. HLMP-3301 and HLMP-3301-F0002 are available in Cut Tape packaging with 5.4mcd brightness. HLMP-3301-D0000 and HLMP-3301-D0002 are available in Bulk and Cut Tape packaging respectively with 2.1mcd brightness. All variants share identical electrical specifications: 1.9V forward voltage, 10mA test current, and 60° viewing angle.

Q: Are there mechanical compatibility concerns with substitute parts?

A: All substitute parts maintain through-hole radial configuration with 5mm lens diameter and compatible height specifications (8.21mm to 9.19mm). PCB footprints designed for MV8190 will accommodate all substitute parts without modification. Lens diameter variations (4.75mm to 5.00mm) are within standard tolerance for 5mm LED applications.

Q: Which substitute part offers the best balance of brightness and availability?

A: The Dialight 5219672F provides 60mcd brightness with 2314 units in stock, offering a practical compromise between the MV8190's 100mcd and lower-brightness alternatives. It operates at 2V forward voltage with 20mA test current, matching the MV8190's current specification. The Würth Elektronik 151051RS11000 provides 30mcd with 3373 units in stock as an alternative mid-range option.

Q: Do all substitute parts meet current compliance standards?

A: All substitute parts are ROHS3 compliant and REACH Unaffected. The MV8190 product status is not specified for RoHS compliance. All substitute parts are classified as active products, ensuring compliance with current regulatory requirements and long-term availability.

Q: What forward voltage adjustment is needed when substituting higher-voltage parts?

A: Substitute parts operate at 1.9V to 2.1V compared to MV8190's 1.7V. For current-limiting resistor designs, the voltage difference of 0.2V to 0.4V represents approximately 1.2% to 2.4% change in total circuit voltage. Most indicator applications tolerate this variation without resistor adjustment. For precision applications, recalculate resistor values using the substitute part's forward voltage specification.
