FLV110 Equivalent & Substitute Parts Reference

Part Overview

The FLV110 is a red diffused LED indicator in T-1 3/4 (5mm) through-hole package manufactured by onsemi. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The FLV110 operates at 1.6V forward voltage with a 20mA test current and delivers 3mcd brightness with a 70° viewing angle. Substitute parts are selected based on matching mechanical form factor, color, lens characteristics, and electrical operating parameters within acceptable ranges for LED indicator applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FLV110 are grouped based on the following substitution criteria:

Primary Matching Parameters:

• Lens size: 5mm T-1 3/4 or 4.83mm diameter (mechanically compatible)
• Color: Red
• Lens transparency: Diffused
• Mounting type: Through hole radial configuration
• Package case: Radial

Electrical Compatibility Range:

• Forward voltage (Vf): 1.6V to 12V (circuit design determines acceptable range)
• Millicandela rating: 2mcd to 8mcd (brightness variation acceptable for indicator applications)
• Peak wavelength: 635nm to 660nm (red spectrum)
• Viewing angle: 35° to 70° (application-dependent)

Product Status Consideration: Substitute parts marked as "Active" provide ongoing availability. The parametric equivalent from Fairchild Semiconductor (FLV110) offers identical electrical specifications with active product status and higher inventory levels.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalent: The FLV110 from Fairchild Semiconductor is the primary replacement option. It maintains identical electrical specifications (1.6V, 3mcd, 660nm) with active product status and ROHS3 compliance. This part requires no circuit redesign and provides the highest compatibility.

Low-Voltage Alternatives (1.6V to 2.2V range):

• HLMP-D150-C0002 (Broadcom): 1.7V forward voltage, 3mcd, 660nm wavelength, active status, ROHS3 compliant. Suitable for direct substitution in low-voltage indicator circuits.
• 5219246F (Dialight): 2.2V forward voltage, 7mcd, 635nm wavelength, active status, ROHS3 compliant. Acceptable for applications tolerating slightly higher forward voltage and brightness.
• 5219320F (Dialight): 1.8V forward voltage, 2mcd, 635nm wavelength, active status, ROHS3 compliant. Suitable for low-brightness indicator applications.

Higher-Voltage Alternatives (5V to 12V range):

• 4302H1-5V (VCC): 5V forward voltage, 8mcd, 635nm wavelength, active status, ROHS3 compliant. Requires circuit redesign for 5V supply systems.
• 4302H1-12V (VCC): 12V forward voltage, 8mcd, 635nm wavelength, active status, ROHS3 compliant. Requires circuit redesign for 12V supply systems.
• 5219183F (Dialight): 7.5V forward voltage, 8mcd, 635nm wavelength, active status, ROHS3 compliant. Requires circuit redesign for 7.5V supply systems.

All substitute parts maintain through-hole radial mounting, red diffused lens configuration, and T-1 3/4 mechanical form factor. Selection depends on circuit supply voltage and brightness requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a 5V LED substitute in a 1.6V circuit without modification? A: No. The 4302H1-5V and similar higher-voltage parts require circuit redesign including appropriate current-limiting resistor recalculation. Direct substitution without circuit modification will result in LED failure or excessive current draw.

Q: What is the difference between 635nm and 660nm wavelength LEDs? A: Both are red LEDs within the visible red spectrum. The 660nm wavelength (FLV110, HLMP-D150-C0002) appears slightly deeper red, while 635nm (Dialight, VCC parts) appears slightly brighter red. For indicator applications, both are functionally equivalent unless specific color matching is required.

Q: Are all substitute parts RoHS compliant? A: The Fairchild FLV110 and all Dialight, VCC, and Broadcom substitute parts listed are ROHS3 compliant. The original onsemi FLV110 (obsolete) does not specify RoHS status.

Q: What is the mechanical difference between 5mm and 4.83mm lens sizes? A: Both fit the T-1 3/4 through-hole form factor. The 4.83mm diameter (Dialight parts) is slightly smaller than the standard 5mm but remains mechanically compatible with standard LED mounting holes and bezels.

Q: Can I substitute a 3mcd LED with an 8mcd LED? A: Yes, for indicator applications. The 8mcd brightness is higher but acceptable for visual indication purposes. However, if the original circuit includes current-limiting resistors sized for 3mcd operation, the brighter LED may appear excessively bright. Verify circuit design allows for brightness variation.

Q: Which substitute offers the closest electrical match to the FLV110? A: The Fairchild Semiconductor FLV110 (1.6V, 3mcd, 660nm) is the closest match. For Broadcom alternatives, the HLMP-D150-C0002 (1.7V, 3mcd, 660nm) provides the next closest electrical compatibility.

Q: What inventory levels are available for these parts? A: Inventory levels are provided in the source data. The Fairchild FLV110 offers the highest availability at 103,254 pieces. Dialight 5219246F provides 3,872 pieces, and VCC 4302H1-5V provides 2,640 pieces. Verify current inventory with your supplier before design finalization.
