MV8112 Equivalent & Substitute Parts Reference

Part Overview

The MV8112 is a red LED indicator from onsemi, configured as a T-1 3/4 through-hole radial component with a 5mm clear domed lens. This part operates at 1.7V forward voltage with a 20mA test current and delivers 940mcd brightness at a 12° viewing angle. The MV8112 is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support. Substitute parts must maintain compatibility with through-hole mounting, radial package configuration, and the electrical operating parameters of the original design.

Substitute Part Grouping Explanation

Substitution eligibility for the MV8112 is determined by the following mandatory parameters:

Mounting Type: Through Hole (required)
Package Configuration: Radial (required)
Lens Size: 5mm, T-1 3/4 (required for mechanical fit)
Lens Style: Round with Domed Top (required)
Lens Transparency: Clear (required)
Color: Red (required)
Voltage - Forward (Vf): 1.7V ±0.5V tolerance range (1.2V to 2.2V acceptable)
Current - Test: 20mA (standard test condition)
Wavelength - Peak: 660nm ±30nm range (630nm to 690nm acceptable)

All substitute parts listed maintain these core parameters within acceptable engineering tolerances. Variations in millicandela rating and viewing angle are permitted provided the substitute meets or exceeds the original brightness specification for the intended application circuit.

Engineering Selection Recommendations

Primary Recommendation: SSL-LX5093XRC-TR

The SSL-LX5093XRC-TR from Lumex Opto/Components Inc. provides the closest electrical match to the MV8112, with identical 1.7V forward voltage and 660nm peak wavelength. This part is actively manufactured and RoHS3 compliant. The increased brightness (1200mcd vs. 940mcd) and wider viewing angle (60° vs. 12°) represent performance improvements suitable for most indicator applications. Tape & Reel packaging supports automated assembly processes.

Secondary Recommendation: SLI-570U2T3F

The SLI-570U2T3F from Rohm Semiconductor is actively produced and offers significantly higher brightness (4000mcd) with a moderate 1.9V forward voltage increase. This part is suitable for applications requiring enhanced visibility. RoHS3 compliance and unlimited moisture sensitivity rating ensure long-term reliability.

Alternative for High-Brightness Applications: OVLGS0C8B9

The OVLGS0C8B9 from TT Electronics / Optek Technology delivers the highest brightness among substitutes (14000mcd) at 2.0V forward voltage. This part is recommended only when the original design circuit can accommodate the increased current draw and forward voltage. The narrower 8° viewing angle suits focused indicator applications.

Parts to Avoid for New Designs:

SLA-580LT3F carries "Not For New Designs" status and should not be selected for new production.
MV8112 itself is obsolete and unavailable for new procurement.

All recommended active substitutes maintain through-hole radial configuration, 5mm T-1 3/4 lens size, clear domed lens style, and red color specification. Forward voltage variations remain within typical circuit tolerance ranges (1.7V to 2.2V). All parts carry REACH Unaffected or ROHS3 Compliant certifications.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute with higher forward voltage than the MV8112?

A: Yes, within limits. The MV8112 operates at 1.7V. Substitutes with forward voltages up to 2.2V are acceptable if your circuit design includes current-limiting resistors. The resistor value may require adjustment to maintain the 20mA test current. Verify your circuit schematic supports the higher voltage drop before selection.

Q: What is the difference between the viewing angles listed for each part?

A: Viewing angle defines the cone of light emission. The MV8112 has a narrow 12° viewing angle, concentrating light in a focused beam. Substitutes with wider angles (30°, 60°) distribute light over a broader area, suitable for applications where the LED is not directly facing the observer. Narrower angles (8°, 10°) concentrate brightness for direct-view applications. Select based on your mechanical mounting and visibility requirements.

Q: Are all substitute parts compatible with my existing PCB layout?

A: All listed substitutes maintain the same through-hole radial package configuration and 5mm T-1 3/4 lens size as the MV8112. Physical fit is compatible. However, verify that your circuit's current-limiting resistor value accommodates the substitute's forward voltage. If the substitute has significantly higher brightness (mcd rating), confirm your application does not require the original lower brightness level.

Q: Which substitute offers the closest performance match?

A: The SSL-LX5093XRC-TR provides the closest electrical match with identical 1.7V forward voltage and 660nm peak wavelength. It is actively manufactured, RoHS3 compliant, and available in Tape & Reel packaging for production environments.

Q: Can I use parts marked "Not For New Designs"?

A: Parts with "Not For New Designs" status, such as SLA-580LT3F, should not be selected for new product development. These parts are in end-of-life phases and may have limited availability or future discontinuation. Use only for legacy system repairs or maintenance of existing products.

Q: What does RoHS3 compliance mean for my application?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All active substitute parts listed carry RoHS3 Compliant or REACH Unaffected certifications, ensuring regulatory compliance for consumer and industrial applications.

Q: How do I determine if a substitute's brightness is sufficient?

A: Compare the millicandela (mcd) rating. The MV8112 delivers 940mcd. Substitutes with equal or higher mcd ratings maintain or exceed the original brightness. If your application requires specific brightness levels, consult your circuit design documentation or conduct bench testing with candidate parts before full production commitment.
