FLV110 Equivalent & Substitute Parts Reference

Part Overview

The FLV110 is a red diffused LED indicator manufactured by Everlight Electronics Co Ltd, designed for through-hole mounting applications. This T-1 3/4 (5mm) lens package LED operates at a forward voltage of 1.6V with a test current of 10mA, delivering 3mcd luminous intensity at a 70° viewing angle. The component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified to address application requirements including alternative voltage ratings, luminous intensity levels, and specific circuit integration needs while maintaining compatibility with the T-1 3/4 through-hole mounting standard.

Engineering Selection Recommendations

Active Status Parts: All substitute parts except HLMP-D150 maintain Active product status, ensuring continued availability and manufacturing support. Selection among active substitutes depends on circuit voltage requirements and luminous intensity specifications.

Voltage-Matched Substitutes:

5219246F (2.2V): Closest voltage match to FLV110 (1.6V), suitable for low-voltage applications with 10mA test current compatibility
5219320F (1.8V): Voltage-compatible alternative with reduced current requirement (2mA), appropriate for current-limited circuit designs
4302H1-5V (5V): Standard logic-level voltage substitute with increased luminous intensity (8mcd)
5219183F (7.5V): Mid-range voltage option for 7.5V circuit integration
4302H1-12V (12V): High-voltage industrial applications with 13mA current specification

Compliance Considerations: All active substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) rating, matching the FLV110 environmental and regulatory requirements. HLMP-D150 is classified as Obsolete and is not recommended for new designs.

Physical Integration: FLV110 offers the lowest profile height (7.49mm) among substitutes. Alternative parts range from 9.57mm to 10.95mm maximum height. PCB layout and enclosure clearance must accommodate the selected substitute's physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can 4302H1-5V directly replace FLV110 in a 1.6V circuit?

A: No. The 4302H1-5V requires 5V forward voltage operation, which is incompatible with 1.6V circuits. Circuit redesign with appropriate current-limiting resistor calculation is required for voltage conversion.

Q: What is the primary difference between 5219246F and 5219320F?

A: Both are Dialight 521 series parts with similar voltage ratings (2.2V vs 1.8V). The 5219320F operates at reduced test current (2mA vs 10mA) and delivers lower luminous intensity (2mcd vs 7mcd). Selection depends on brightness requirements and available circuit current capacity.

Q: Are all substitute parts compatible with the same PCB footprint as FLV110?

A: All substitute parts use through-hole radial T-1 3/4 (5mm) mounting packages with compatible lead spacing. However, physical height variations (7.49mm to 10.95mm) may affect enclosure fit and component clearance. Verify mechanical constraints before substitution.

Q: Why is HLMP-D150 listed if it is Obsolete?

A: HLMP-D150 is included in the reference data as a historical substitute record. Obsolete status indicates discontinued manufacturing and unavailable inventory. This part is not recommended for new designs or replacements.

Q: What viewing angle differences exist among substitutes?

A: FLV110 provides 70° viewing angle. Most substitutes (4302H1 series and 5219183F) offer 60° viewing angle. 5219320F provides 50° viewing angle. Narrower viewing angles concentrate luminous intensity in a smaller cone, affecting visibility from off-axis positions.

Q: Can I use 4302H1-12V in a 5V application?

A: No. The 4302H1-12V is specified for 12V operation. Using it in a 5V circuit will result in insufficient forward voltage and non-functional LED operation. Use 4302H1-5V for 5V applications.

Q: What is the wavelength difference between FLV110 and Dialight substitutes?

A: FLV110 operates at 660nm peak wavelength (deep red). Dialight 521 series substitutes (5219246F, 5219320F, 5219183F) operate at 635nm peak wavelength (standard red). Both are red LEDs; the wavelength difference affects perceived color tone and spectral response in optical sensing applications.
