HLMP-3366 Equivalent & Substitute Parts

Part Overview

The HLMP-3366 is a red LED indicator light manufactured by Broadcom Limited, designed for through-hole mounting applications. This T-1 3/4 (5mm) package LED operates at 1.9V forward voltage with a 13.8mcd brightness rating and features a clear lens for direct light transmission. The component is Active status and fully compliant with RoHS3 and REACH regulations, making it suitable for current production environments. Substitute parts may be required due to inventory constraints, supply chain discontinuities, or specific application requirements for alternative optical or electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

The MV50154 (Fairchild Semiconductor) qualifies as a substitute for the HLMP-3366 based on the following alignment of critical parameters:

Matching Parameters:

• Color: Red
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole
• Viewing Angle: 50°
• Height (Max): 6.35mm
• Package / Case: Radial
• Product Status: Active
• RoHS3 Compliance: Yes

Differing Parameters:

• Lens Transparency: Diffused (vs. Clear on HLMP-3366)
• Millicandela Rating: 1.5mcd (vs. 13.8mcd on HLMP-3366)
• Voltage - Forward (Vf) (Typ): 1.6V (vs. 1.9V on HLMP-3366)
• Wavelength - Peak: 660nm (vs. 635nm on HLMP-3366)

The MV50154 maintains mechanical and electrical compatibility through identical package geometry, mounting configuration, and test current specifications. Differences in optical output and forward voltage reflect design variations between manufacturers but do not preclude functional substitution in applications where the lower brightness and diffused lens characteristics are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the HLMP-3366 and MV50154 maintain Active product status and full RoHS3 compliance, ensuring regulatory alignment for current production use. The HLMP-3366 is the primary specification with higher brightness output (13.8mcd) and clear lens transmission, suitable for applications requiring maximum light intensity and direct visibility. The MV50154 provides a lower-brightness alternative (1.5mcd) with diffused lens characteristics, appropriate for applications where reduced intensity or light diffusion is acceptable. Forward voltage differences (1.9V vs. 1.6V) require circuit-level verification to ensure proper current-limiting resistor sizing and LED driver compatibility. Both components share identical mechanical footprints and mounting requirements, enabling direct PCB substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the MV50154 directly replace the HLMP-3366 on existing PCBs?

A: Yes, mechanical and mounting compatibility is maintained. Both components use identical T-1 3/4 (5mm) radial packages with 6.35mm maximum height and 50° viewing angles. PCB footprints and through-hole spacing are compatible without layout changes.

Q: What are the optical differences between these parts?

A: The HLMP-3366 features a clear lens with 13.8mcd brightness, while the MV50154 has a diffused lens with 1.5mcd brightness. The diffused lens scatters light over a wider area at lower intensity, whereas the clear lens concentrates light for higher directional brightness.

Q: Do the forward voltage differences affect circuit design?

A: Yes. The HLMP-3366 operates at 1.9V typical forward voltage, while the MV50154 operates at 1.6V. Current-limiting resistor values must be recalculated based on the specific LED forward voltage to maintain proper 10mA test current operation. Verify LED driver specifications for voltage compatibility.

Q: Are both parts RoHS3 compliant?

A: Yes, both the HLMP-3366 and MV50154 are ROHS3 Compliant, meeting current environmental and regulatory requirements for production applications.

Q: What is the wavelength difference between these LEDs?

A: The HLMP-3366 has a 635nm peak wavelength, while the MV50154 has a 660nm peak wavelength. Both emit red light within the visible spectrum, with the MV50154 shifted slightly toward the far-red region.
