MV8705 LED Orange Clear T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The MV8705 is an orange 615nm LED indication component manufactured by onsemi, designed for through-hole mounting in discrete applications. This part operates at 2.1V forward voltage with a 2400mcd brightness rating and 20° viewing angle. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design support, maintenance, and production continuity. Suitable alternatives must maintain compatibility with the through-hole radial package format, similar electrical characteristics, and comparable optical performance within acceptable tolerances.

Substitute Part Grouping Explanation

Substitution logic for the MV8705 is based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

Lens Size: 5mm, T-1 3/4 form factor (physical fit in PCB and housing)
Mounting Type: Through Hole radial configuration
Package / Case: Radial (mechanical and electrical interface)
Lens Transparency: Clear (optical consistency)
Voltage - Forward (Vf): 2.1V ±0.2V tolerance range (circuit design compatibility)
Current - Test: 20mA standard test condition
Viewing Angle: 20° ±10° acceptable range (application-dependent visibility requirements)

Secondary Compatibility Considerations:

Millicandela Rating: 2400mcd ±50% acceptable variance (brightness performance)
Wavelength - Dominant: 615nm orange spectrum (color consistency)
Height (Max): 8.89mm ±0.2mm (mechanical clearance)

Substitute parts are grouped into two categories: direct orange LED replacements (matching color and wavelength) and alternative color options (yellow and amber) that maintain electrical and mechanical compatibility for applications where color substitution is acceptable.

Engineering Selection Recommendations

Direct Orange Replacements (Preferred for Color-Critical Applications):

The Broadcom Limited HLMP series orange LEDs (HLMP-EJ30-NR0DD, HLMP-EJ24-QT000, HLMP-EJ08-WZ000) are active products with ROHS3 compliance and provide direct color matching to the MV8705. These parts maintain the 5mm T-1 3/4 through-hole radial package format and operate within compatible voltage ranges (1.98V vs. 2.1V nominal). The HLMP-EJ30-NR0DD offers the closest brightness match at 1290mcd with a 30° viewing angle and is available in high inventory (19,741 pcs) in Cut Tape packaging. The HLMP-EJ24-QT000 provides 2175mcd brightness with a 23° viewing angle, closely matching the original MV8705 specifications. Selection between these orange alternatives depends on specific viewing angle and brightness requirements for the application.

Alternative Color Options (Yellow and Amber):

Yellow LED substitutes including OVLFY3C7, OVLGY0C9B9, SLI-570Y2T3F, and LTL2R3KSK maintain electrical and mechanical compatibility while offering different brightness and viewing angle characteristics. These parts are suitable for applications where color substitution is acceptable. The OVLFY3C7 provides 7400mcd at 30° viewing angle with 2V forward voltage. The SLI-570Y2T3F matches the original 2.1V forward voltage and 20° viewing angle with 5200mcd brightness. The Broadcom HLMP-EL15-VY0DD amber LED offers an intermediate color option with 8100mcd brightness and 2.02V forward voltage.

Compliance and Availability:

All recommended substitute parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. Inventory availability is strong across all alternatives, with OVLGY0C9B9 offering the highest stock level (79,595 pcs). Packaging options include Bulk, Cut Tape, and Tape & Box formats to accommodate different procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can I use a yellow LED as a direct replacement for the orange MV8705?

A: Yellow LEDs such as OVLFY3C7, SLI-570Y2T3F, and LTL2R3KSK maintain full electrical and mechanical compatibility with the MV8705 through-hole radial package. However, they produce a different color output (yellow vs. orange). Substitution is acceptable only if the application does not require specific orange color indication. Verify that the circuit design and end-user requirements permit color variation before implementing a yellow substitute.

Q: What is the voltage tolerance for substituting the MV8705?

A: The MV8705 operates at 2.1V forward voltage. Substitute parts with forward voltages between 1.98V and 2.2V are electrically compatible within standard circuit design tolerances. The Broadcom HLMP series operates at 1.98V, while the Rohm SLI-570Y2T3F and Lite-On LTL2R3KSK operate at 2.1V and 2.05V respectively. Verify that your circuit current-limiting resistor design accommodates the forward voltage variation of the selected substitute.

Q: Are all substitute parts available in the same through-hole radial package?

A: All recommended substitute parts use the 5mm T-1 3/4 through-hole radial package format, ensuring mechanical compatibility with PCB footprints designed for the MV8705. The Dialight 5219466F uses a slightly smaller 4.83mm diameter lens, which may require footprint verification. Confirm package dimensions against your PCB design before finalizing component selection.

Q: What brightness differences should I expect when substituting the MV8705?

A: The MV8705 provides 2400mcd brightness. Direct orange replacements vary: HLMP-EJ30-NR0DD offers 1290mcd (54% lower), while HLMP-EJ24-QT000 provides 2175mcd (91% of original). Yellow alternatives range from 1150mcd (LTL2R3KSK) to 14000mcd (OVLGY0C9B9). Select a substitute based on your application's brightness requirements. Lower brightness parts reduce power consumption and heat generation, while higher brightness parts improve visibility in bright ambient conditions.

Q: Which substitute offers the closest match to the original MV8705 specifications?

A: The HLMP-EJ24-QT000 provides the closest overall match with 2175mcd brightness, 23° viewing angle (vs. 20° original), and 8.91mm height. It maintains orange color, 5mm T-1 3/4 package format, and operates at 1.98V forward voltage. This part is active, ROHS3 compliant, and available in bulk packaging with 959 pcs in stock.

Q: Can I substitute based on viewing angle alone?

A: Viewing angle is an application-specific parameter. The MV8705 provides 20° viewing angle. Substitutes range from 8° (narrow beam) to 30° (wide beam). Select viewing angle based on your application's visibility requirements and mounting geometry. Narrower viewing angles concentrate brightness in a specific direction, while wider angles distribute light across a broader area. Verify that the selected substitute's viewing angle meets your application's optical requirements.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Bulk (loose components), Cut Tape (CT), and Tape & Box (TB). Bulk packaging is standard for most alternatives and offers cost efficiency for larger quantities. Cut Tape packaging (HLMP-EJ30-NR0DD) provides component protection during handling. Tape & Box packaging (HLMP-EL15-VY0DD) combines protection with organized storage. Select packaging based on your procurement volume, assembly process, and inventory management requirements.
