MV8813 LED Red Clear T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The MV8813 is a red LED indicator from onsemi designed for through-hole mounting applications. It features a 5mm T-1 3/4 lens package with a clear, domed top configuration and operates at a forward voltage of 2.1V with a 20mA test current. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MV8813 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Lens size and package type (5mm, T-1 3/4, through-hole radial mounting)
• Color (red LED indication)
• Lens configuration (clear, domed top)
• Forward voltage range (2.1V nominal, with tolerance consideration)
• Test current (20mA standard)
• Millicandela rating (brightness level)
• Viewing angle (directional characteristics)
• Wavelength specifications (dominant and peak wavelengths in red spectrum)

The MV8813 has two identified substitute parts: LTL2R3KEK (Lite-On Inc., active status) and MV8112 (onsemi, obsolete status). Both maintain the same physical package, mounting configuration, and core LED specifications while offering variations in forward voltage, brightness, and viewing angle that remain within acceptable substitution parameters for red LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

LTL2R3KEK (Lite-On Inc.) is the preferred substitute for new designs and production continuity. This part maintains active product status, ensuring long-term availability and supply chain stability. The forward voltage of 2.05V is within 0.05V of the MV8813 specification, and the 20mA test current remains identical. The millicandela rating of 700mcd represents a 25% reduction in brightness compared to the MV8813, which is acceptable for standard indication applications. The expanded viewing angle of 30° versus 12° provides broader visibility characteristics. The wavelength specifications (624nm dominant, 632nm peak) remain within the red spectrum and are compatible with the original part's 623nm/630nm specifications. RoHS3 compliance provides regulatory advantage for new product development.

MV8112 (onsemi) is a parametric equivalent within the same manufacturer family. This part shares the same 940mcd brightness rating and 12° viewing angle as the MV8813. However, the significantly lower forward voltage of 1.7V requires circuit design verification to ensure proper current limiting and brightness control. The peak wavelength of 660nm represents a shift toward the far-red spectrum compared to the MV8813's 630nm, which may affect color perception in certain applications. The obsolete status of this part limits its suitability for new production.

Frequently Asked Questions (FAQ)

Q: Can LTL2R3KEK be used as a direct replacement for MV8813 without circuit modification?

A: LTL2R3KEK is mechanically and electrically compatible with MV8813 for standard through-hole LED indication circuits. The forward voltage difference of 0.05V is negligible in typical current-limiting resistor designs. However, the reduced brightness (700mcd vs. 940mcd) and expanded viewing angle (30° vs. 12°) should be evaluated against application requirements. No circuit modification is required for basic functionality.

Q: What is the primary difference between LTL2R3KEK and MV8112?

A: The primary difference is forward voltage. LTL2R3KEK operates at 2.05V, closely matching the MV8813's 2.1V specification. MV8112 operates at 1.7V, requiring circuit design verification to maintain proper brightness and current control. Both maintain the same 5mm T-1 3/4 package and through-hole radial mounting configuration.

Q: Why does MV8112 have a lower forward voltage than MV8813?

A: Forward voltage variation in LEDs results from differences in semiconductor material composition and manufacturing processes. MV8112's 1.7V forward voltage indicates a different die design or material chemistry compared to MV8813's 2.1V, despite both being red LEDs from onsemi. This difference affects circuit design and brightness control.

Q: Is the wavelength difference between MV8813 (630nm peak) and MV8112 (660nm peak) significant?

A: The 30nm difference places MV8112 in the far-red spectrum while MV8813 remains in the standard red spectrum. For general indication applications, this difference is typically imperceptible to human vision. However, for color-critical applications or systems with wavelength-specific sensors, this difference should be evaluated.

Q: Can LTL2R3KEK be used in applications requiring the narrow 12° viewing angle of MV8813?

A: LTL2R3KEK's 30° viewing angle is wider than MV8813's 12° specification. For applications requiring narrow-angle directional indication, this broader viewing angle may not meet requirements. MV8112 maintains the 12° viewing angle but introduces forward voltage and wavelength considerations that require circuit verification.

Q: What is the inventory status for these substitute parts?

A: LTL2R3KEK has 9,468 pieces in stock with active product status, ensuring supply continuity. MV8112 has 1,032 pieces in stock but is classified as obsolete, limiting long-term availability. For production planning, LTL2R3KEK is the recommended choice.

Q: Are there compliance or regulatory differences between these parts?

A: LTL2R3KEK carries RoHS3 compliance certification, meeting current environmental regulations for new product development. MV8813 and MV8112 are listed as REACH Unaffected. All three parts carry EAR99 ECCN classification and identical HTSUS codes (8541.41.0000), indicating equivalent regulatory treatment for export and trade purposes.
