Engineering Selection Recommendations

Primary Substitutes (Active Status, Closest Parameter Match):

SSL-LX5093SRC/E (Lumex Opto/Components Inc.) is the closest functional equivalent to MV8111. This part maintains identical forward voltage (1.7V), identical peak wavelength (660nm), and identical test current (20mA). The primary difference is increased brightness (2800mcd vs 370mcd) and wider viewing angle (30° vs 12°). This part is Active product status with ROHS3 compliance and unlimited MSL rating. Inventory availability is highest among all substitutes at 53806 pieces.

SLA-580LT3F (Rohm Semiconductor) provides near-identical electrical characteristics with 1.75V forward voltage and 660nm wavelength. Brightness is 470mcd with 10° viewing angle. This part is classified as Not For New Designs, indicating it remains available but is not recommended for new circuit designs. Use only when existing designs require component continuity.

Secondary Substitutes (Active Status, Acceptable Parameter Range):

SLI-570U2T3F (Rohm Semiconductor) operates at 1.9V forward voltage with 630nm wavelength and 4000mcd brightness. Active product status with ROHS3 compliance. Wider 20° viewing angle accommodates applications requiring broader light distribution.

WP7113SEC/J3 and WP7113SECK/J3 (Kingbright) operate at 2.2V forward voltage with 625nm dominant wavelength and 640nm peak wavelength. Both are Active status with ROHS3 compliance. WP7113SEC/J3 provides 8000mcd brightness; WP7113SECK/J3 provides 6000mcd. Both feature 20° viewing angle. Circuit design must accommodate 0.5V higher forward voltage compared to MV8111.

XLM2MR12W (SunLED VersoLED series) operates at 2.1V forward voltage with 640nm dominant wavelength and 660nm peak wavelength. Provides 4990mcd brightness with 20° viewing angle. Active product status with ROHS3 compliance.

OVLGS0C8B9 (TT Electronics / Optek Technology) operates at 2V forward voltage with 623nm dominant wavelength. Provides highest brightness at 14000mcd with narrowest viewing angle at 8°. Active product status with ROHS3 compliance. Use when high brightness and narrow directional focus are required.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), matching the MV8111 regulatory profile. All parts carry EAR99 ECCN classification and 8541.41.0000 HTSUS code consistent with the main part.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX5093SRC/E directly replace MV8111 without circuit modification?

A: Yes. SSL-LX5093SRC/E maintains identical forward voltage (1.7V) and test current (20mA) as MV8111. No resistor recalculation is required. The increased brightness (2800mcd vs 370mcd) and wider viewing angle (30° vs 12°) are functional improvements that do not require circuit changes.

Q: What is the impact of forward voltage differences when substituting with WP7113SEC/J3?

A: WP7113SEC/J3 operates at 2.2V forward voltage compared to MV8111's 1.7V. This 0.5V difference requires recalculation of the current-limiting resistor value. For a given supply voltage, the resistor value must be adjusted downward to maintain 20mA test current. Verify the circuit design accommodates this adjustment before substitution.

Q: Why is SLA-580LT3F marked as "Not For New Designs"?

A: SLA-580LT3F carries this designation from Rohm Semiconductor, indicating the part remains available for existing applications but is not recommended for new circuit designs. Use this part only when maintaining compatibility with existing designs or when no other suitable substitute is available. For new designs, select from parts with Active product status.

Q: Are all substitute parts compatible with standard through-hole PCB assembly equipment?

A: Yes. All substitute parts maintain T-1 3/4 (5mm) lens size, radial package configuration, and through-hole mounting type. Physical form factor is identical across all listed parts. Standard PCB assembly equipment and existing footprints accommodate all substitutes without modification.

Q: What is the difference between wavelength dominant and wavelength peak specifications?

A: Wavelength dominant represents the primary color perception wavelength. Wavelength peak represents the actual spectral peak of the LED emission. Both values are provided where available in the specification data. For red LED indication applications, both values fall within the red spectrum range (623nm to 660nm) across all substitute parts.

Q: Which substitute offers the best brightness-to-viewing-angle balance for general indication applications?

A: Selection depends on specific application requirements. SSL-LX5093SRC/E provides moderate brightness (2800mcd) with wide viewing angle (30°), suitable for applications requiring visibility from multiple angles. WP7113SEC/J3 provides high brightness (8000mcd) with moderate viewing angle (20°), suitable for applications requiring high visibility from a defined direction. OVLGS0C8B9 provides maximum brightness (14000mcd) with narrow viewing angle (8°), suitable for focused indication applications.

Q: Do all substitute parts carry the same regulatory certifications as MV8111?

A: Yes. All substitute parts listed are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). All carry EAR99 ECCN classification and 8541.41.0000 HTSUS code. Regulatory compliance is maintained across all substitutes.

Q: Can OVLGS0C8B9 be used in applications where narrow directional focus is critical?

A: Yes. OVLGS0C8B9 features the narrowest viewing angle (8°) among all substitutes, providing focused light distribution. The 14000mcd brightness rating is the highest available. This part is suitable for applications requiring concentrated light output in a specific direction. Forward voltage is 2V, requiring resistor recalculation in the circuit design.
