HLMP47199MP8 Equivalent & Substitute Parts

Part Overview

The HLMP47199MP8 is a quad-wide yellow LED circuit board indicator manufactured by onsemi, configured as a 4-element array in a single 5mm T-1 3/4 through-hole package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part operates at 1.9V with 2mA test current and delivers 2.1mcd luminous intensity with a 50° viewing angle, suitable for low-power indicator applications requiring diffused yellow illumination.

Substitute Part Grouping Explanation

Substitution for the HLMP47199MP8 is determined by the following critical parameters:

Primary Substitution Criteria:

Color: Yellow
Lens Size: 5mm, T-1 3/4 form factor

The HLMP47199MP8 is a quad-element array package. Direct substitutes must maintain electrical compatibility (1.9V, 2mA) and physical form factor (5mm T-1 3/4 through-hole). Single-element alternatives are listed where they meet the core electrical and optical parameters, though they require circuit redesign for array applications.

Engineering Selection Recommendations

Best Electrical Match - Low Voltage Applications: 5219321F (Dialight) provides the closest electrical compatibility with 1.9V forward voltage and 2mA test current, matching the original specification exactly. This part is active and ROHS3 compliant. The 4.83mm lens diameter is slightly smaller than the 5mm T-1 3/4 form factor but maintains through-hole mounting compatibility. Wavelength peak at 583nm is within the yellow spectrum range.

Best Form Factor Match - 5mm T-1 3/4 Package: HLMP-3401-E0002 (Broadcom Limited) maintains the exact 5mm T-1 3/4 lens size and through-hole mounting. This part is active and ROHS3 compliant. Forward voltage is 2V (0.1V higher than original) with 10mA test current (5x higher). Millicandela rating of 5.7mcd exceeds the original 2.1mcd. This part requires circuit current-limiting adjustment but provides superior brightness and availability.

Alternative for 1.9V Systems: 5219327F (Dialight) operates at 1.8V with 2mA test current, providing near-exact electrical compatibility. This part is active and ROHS3 compliant. Color is green with 565nm peak wavelength, matching the original green-yellow spectrum. Lens size is 4.83mm diameter with 50° viewing angle, identical to the original specification.

Higher Voltage Alternative: HLMP-3650 (Broadcom Limited) is specified for 5V operation with 10mA test current. This part is active and ROHS3 compliant. It maintains the 5mm T-1 3/4 form factor and through-hole mounting. Use only in applications where 5V supply is available and circuit design permits higher current draw.

Frequently Asked Questions (FAQ)

Q: Can I use 5219321F as a direct replacement for HLMP47199MP8? A: 5219321F matches the electrical parameters (1.9V, 2mA) and viewing angle (50°) exactly. The lens diameter is 4.83mm versus 5mm, which may affect mechanical fit in some PCB layouts. Verify physical clearance before substitution.

Q: What is the difference between the quad-wide HLMP47199MP8 and single-element substitutes? A: HLMP47199MP8 is a 4-element array in one package. Single-element substitutes (5219321F, 5219327F, HLMP-3401-E0002, HLMP-3650) require circuit redesign to accommodate four separate components. Array functionality cannot be replicated with single-element parts without PCB layout changes.

Q: Why does HLMP-3401-E0002 have higher current (10mA) than the original (2mA)? A: HLMP-3401-E0002 is specified with 10mA test current, which is a standard measurement condition for that part family. Circuit design must include appropriate current-limiting resistors to operate at lower currents if required by the application.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL-1 (Unlimited) moisture sensitivity rating, matching the original part's environmental specifications.

Q: Can I substitute HLMP-3650 (5V) in a 1.9V circuit? A: No. HLMP-3650 requires 5V forward voltage and cannot operate reliably at 1.9V. Use only in circuits designed for 5V LED operation.

Q: What is the wavelength difference between 565nm and 583nm? A: Both wavelengths fall within the yellow spectrum. 565nm appears as green-yellow, while 583nm appears as pure yellow. Visual appearance difference is minimal in typical indicator applications.
