Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

SSL-LX5093SRC/E (Lumex Opto/Components Inc.) represents the closest electrical match to the MV8112, sharing identical forward voltage (1.7V) and peak wavelength (660nm). This part maintains Active product status with full ROHS3 compliance and REACH unaffected designation. The increased millicandela rating (2800mcd vs 940mcd) and wider viewing angle (30° vs 12°) provide enhanced optical performance without compromising circuit compatibility. Current inventory of 53,806 units ensures supply continuity.

SLI-570U2T3F (Rohm Semiconductor, SLI-570x series) offers Active product status with moderate forward voltage variation (1.9V) and peak wavelength within red spectrum (630nm). The 4000mcd rating and 20° viewing angle provide balanced optical characteristics. This part is suitable for applications where slightly higher forward voltage is acceptable within circuit design margins.

Secondary Substitutes (Acceptable with Circuit Review):

WP7113SEC/J3 and WP7113SECK/J3 (Kingbright) both maintain Active status with 2.2V forward voltage and 640nm peak wavelength. These parts require circuit verification to confirm voltage tolerance, as the 0.5V increase from the MV8112 specification may impact current-limiting resistor calculations. The 8000mcd and 6000mcd ratings respectively provide higher brightness options.

XLM2MR12W (SunLED, VersoLED series) operates at 2.1V with 660nm peak wavelength matching the MV8112 color specification. Active product status and 4990mcd rating make this part suitable for direct substitution with minor circuit adjustment consideration.

Not Recommended for New Designs:

SLA-580LT3F (Rohm Semiconductor) carries "Not For New Designs" product status designation, indicating manufacturer end-of-life trajectory. While electrically compatible (1.75V, 660nm), this part should be avoided for new product development despite current inventory availability (1,557 units).

Brightness-Optimized Alternative:

OVLGS0C8B9 (TT Electronics / Optek Technology) delivers the highest millicandela rating (14000mcd) among all substitutes, suitable for applications requiring maximum luminous intensity. The 2.0V forward voltage and 623nm wavelength require circuit verification. Narrower viewing angle (8° vs 12°) concentrates light output. Substantial inventory (31,283 units) supports high-volume applications.

All recommended substitutes maintain ROHS3 compliance, MSL 1 rating, and EAR99 ECCN classification consistent with the MV8112 regulatory profile.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MV8112 with SSL-LX5093SRC/E without circuit modification?

A: Yes. SSL-LX5093SRC/E matches the MV8112 forward voltage (1.7V) and peak wavelength (660nm) exactly. Both operate at 20mA test current with identical package geometry (T-1 3/4, 5mm, radial). No circuit redesign is required. The increased brightness (2800mcd vs 940mcd) and wider viewing angle (30° vs 12°) represent performance enhancements without compatibility issues.

Q: What is the maximum forward voltage variation acceptable for substitution?

A: The MV8112 operates at 1.7V typical. Substitute parts ranging from 1.7V to 2.2V are listed as acceptable alternatives. However, forward voltage directly affects current-limiting resistor calculations in series circuits. A 0.5V increase (from 1.7V to 2.2V) reduces current flow by approximately 5-10% depending on total circuit voltage and resistor value. Verify that your circuit design accommodates this variation or recalculate resistor values accordingly.

Q: Are all substitute parts mechanically compatible with the MV8112 PCB footprint?

A: Yes. All substitute parts maintain identical mechanical specifications: 5mm T-1 3/4 lens size, round domed top geometry, clear lens transparency, radial lead configuration, and through-hole mounting. Maximum heights range from 8.60mm to 8.90mm, all within standard PCB clearance tolerances. Direct PCB footprint compatibility is confirmed for all listed substitutes.

Q: Which substitute offers the closest color match to the MV8112?

A: SSL-LX5093SRC/E and XLM2MR12W both match the MV8112 peak wavelength at 660nm, providing identical red color specification. OVLGS0C8B9 operates at 623nm (orange-red shift), while WP7113SEC/J3 and WP7113SECK/J3 operate at 640nm (slight color variation). For applications requiring precise color matching, select parts with 660nm peak wavelength.

Q: What is the difference between OVLGS0C8B9 and the MV8112 in terms of brightness?

A: OVLGS0C8B9 delivers 14000mcd compared to MV8112's 940mcd, representing approximately 15 times greater luminous intensity. This higher brightness results from different LED die design and optical lens characteristics. OVLGS0C8B9 also features a narrower viewing angle (8° vs 12°), concentrating light output into a tighter beam pattern. Select OVLGS0C8B9 only if your application requires significantly higher brightness; standard indication applications may find this excessive.

Q: Can I use WP7113SEC/J3 as a direct replacement despite the 2.2V forward voltage?

A: WP7113SEC/J3 requires circuit verification before substitution. The 2.2V forward voltage represents a 0.5V increase from the MV8112's 1.7V specification. In a typical series circuit with a current-limiting resistor, this voltage difference reduces LED current by approximately 5-10%. If your circuit design includes voltage tolerance margin or adjustable resistor values, substitution is feasible. Recalculate resistor values using Ohm's law: R = (Vsupply - Vf) / Iled to confirm adequate current delivery.

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

A: "Not For New Designs" designation indicates that Rohm Semiconductor has discontinued active development and marketing of this part. While SLA-580LT3F remains electrically compatible (1.75V, 660nm, 470mcd), the manufacturer is transitioning inventory toward end-of-life. New product designs should select from Active status parts (SSL-LX5093SRC/E, SLI-570U2T3F, WP7113SEC/J3, XLM2MR12W, OVLGS0C8B9) to ensure long-term supply availability and manufacturer support.

Q: What viewing angle should I select for my application?

A: Viewing angle determines the beam width of light output. The MV8112 specifies 12° viewing angle, suitable for standard indication applications where light visibility is required across a moderate angular range. Narrower angles (8° with OVLGS0C8B9) concentrate brightness into a tight beam, useful for focused indicator applications. Wider angles (20-30° with Kingbright, Lumex, and SunLED parts) distribute light across a broader area, suitable for applications requiring visibility from multiple viewing positions. Select viewing angle based on your specific application geometry and visibility requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance certification, matching the MV8112 regulatory status. All parts also maintain MSL 1 (Unlimited) moisture sensitivity rating and EAR99 ECCN classification. No regulatory or compliance issues arise from substitution within this parts list.

Q: Which substitute offers the best inventory availability?

A: SSL-LX5093SRC/E (Lumex Opto/Components Inc.) provides the highest current inventory with 53,806 units in stock, ensuring supply continuity for high-volume applications. OVLGS0C8B9 (TT Electronics / Optek Technology) offers 31,283 units. For standard applications, SSL-LX5093SRC/E represents the optimal choice combining electrical compatibility, Active product status, and maximum inventory availability.
