MV33509MP6 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The MV33509MP6 is a yellow circuit board indicator LED manufactured by onsemi, featuring a 5mm round domed lens with right-angle through-hole mounting. This part operates at 2.2V forward voltage with 20mA test current and delivers 150mcd brightness. The product is currently obsolete, making equivalent substitutes necessary for ongoing design support and production continuity. Suitable alternatives must maintain compatibility with the electrical specifications (2.2V nominal operation, 20mA current rating) and mechanical form factor (5mm through-hole, right-angle configuration).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MV33509MP6 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Yellow (required)
• Voltage - Forward (Vf): 2.0V to 2.2V range (allows operation within standard circuit designs)
• Current - Test: 20mA (standard test current for this LED category)
• Mounting Type: Through Hole (mechanical compatibility)
• Lens Size: 5mm or T-1 3/4 form factor (physical fit)
• Configuration: Single LED (functional equivalence)

Secondary Considerations:

• Wavelength - Peak: 583nm to 592nm (yellow spectrum consistency)
• Millicandela Rating: Brightness within acceptable range for indicator applications
• Lens Transparency: Clear or Tinted (visual performance)
• Product Status: Active preferred for long-term availability

Parts meeting the primary criteria are considered direct substitutes. Variations in millicandela rating, viewing angle, and lens transparency are acceptable provided the electrical and mechanical parameters align with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

4308H7 (VCC) and WP1503YC (Kingbright) are the most direct electrical equivalents, matching the 2.2V forward voltage and 20mA test current of the MV33509MP6. Both are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance and long-term availability. The 4308H7 delivers 140mcd brightness with a 24° viewing angle, while the WP1503YC provides 50mcd with a 30° viewing angle. Both feature 5mm T-1 3/4 form factors suitable for through-hole mounting.

SSL-LX5063YC and SSL-LX5093YC (Lumex) operate at 2.1V forward voltage with 20mA test current, placing them within acceptable tolerance for most circuit designs. Both deliver 40mcd brightness with 30° viewing angles and are available as active products with full compliance certifications.

Secondary Substitutes (Electrical Compatibility with Brightness Variation):

151051YS04000 (Würth Elektronik) operates at 2V forward voltage with 20mA test current but delivers significantly higher brightness at 450mcd. This part is suitable for applications where increased luminous intensity is acceptable or beneficial. The diffused lens provides different light distribution compared to the original tinted lens.

OVLLY8C7 (TT Electronics/Optek Technology) operates at 2V forward voltage with 20mA test current and delivers the highest brightness at 980mcd. This part features a flat-top lens and 100° viewing angle, making it suitable for applications requiring wide-angle visibility. The clear lens and elevated brightness represent a significant departure from the original specification but maintain electrical compatibility.

Not Recommended:

5219284F and 5219321F (Dialight) operate at significantly different voltage and current ratings (10V/10mA and 1.9V/2mA respectively) and are not suitable substitutes for the MV33509MP6 in standard 2.2V/20mA circuit designs.

LTL2R3KFK (Lite-On Inc.) is an orange LED (605nm dominant wavelength) and does not meet the yellow color requirement.

Frequently Asked Questions (FAQ)

Q: Can I use OVLLY8C7 as a direct replacement for MV33509MP6?

A: OVLLY8C7 is electrically compatible, operating at 2V forward voltage with 20mA test current. However, it delivers 980mcd brightness compared to the original 150mcd, and features a flat-top lens with 100° viewing angle versus the original domed lens. Use this substitute only if the increased brightness and wider viewing angle are acceptable for your application.

Q: What is the difference between the Würth Elektronik 151051YS04000 and the original MV33509MP6?

A: The 151051YS04000 operates at 2V forward voltage (versus 2.2V) and delivers 450mcd brightness (versus 150mcd). It features a diffused yellow lens instead of a tinted lens, which affects light distribution. The 4.90mm lens diameter is slightly smaller than the original 5.00mm. This part is suitable if higher brightness and diffused light output are acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all active substitute parts listed (151051YS04000, 4308H7, OVLLY8C7, WP1503YC, SSL-LX5063YC, SSL-LX5093YC) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute offers the closest match to the original MV33509MP6 specifications?

A: The 4308H7 (VCC) provides the closest electrical match with identical 2.2V forward voltage and 20mA test current. The 140mcd brightness is within 7% of the original 150mcd rating. The WP1503YC (Kingbright) is also highly compatible at 2.1V forward voltage with 20mA test current, though brightness is lower at 50mcd.

Q: Can I use these substitutes in existing PCB designs without modification?

A: All listed substitutes use through-hole mounting compatible with standard 5mm LED footprints. However, verify that your PCB layout accommodates the specific lens size and mounting orientation. The right-angle configuration of the original MV33509MP6 should be matched with substitutes offering similar mounting geometry.

Q: What is the difference between clear and tinted lens types?

A: The original MV33509MP6 features a tinted lens, which provides inherent color filtering and typically reduces brightness compared to clear lenses. Clear lens substitutes (4308H7, OVLLY8C7, WP1503YC, SSL-LX5063YC, SSL-LX5093YC) transmit more light but rely on the LED die color for yellow appearance. Diffused lens substitutes (151051YS04000) scatter light for wider, softer illumination.

Q: How do viewing angles affect substitute selection?

A: The original MV33509MP6 does not specify a viewing angle. Substitute parts range from 24° (4308H7, narrow focus) to 100° (OVLLY8C7, wide dispersion). Select based on your application requirements: narrow angles for focused indicator lights, wide angles for general visibility.

Q: Are there inventory considerations for these substitutes?

A: All substitute parts are currently in stock with active product status. Inventory levels vary: WP1503YC has the highest availability at 20,690 pieces, while OVLLY8C7 has 9,819 pieces. Würth Elektronik 151051YS04000 and Dialight 5219321F also maintain substantial inventory levels above 1,700 pieces.
