Engineering Selection Recommendations
Direct Electrical Substitutes (Minimal Circuit Redesign):
151031VS06000 (Würth Elektronik) and HLMP-1790 (Broadcom) provide the closest electrical match to the TLHG4600. The 151031VS06000 operates at 2.2V with 20mA test current and delivers 30mcd brightness. The HLMP-1790 operates at 1.9V with 2mA test current and delivers 2.3mcd brightness. Both are ROHS3 compliant with unlimited moisture sensitivity.
Brightness-Optimized Substitutes:
5219430F (Dialight) offers the highest brightness at 50mcd with 2.1V forward voltage and 10mA test current, suitable for applications requiring enhanced visibility. This part features clear lens transparency rather than diffused.
Low-Power Substitutes:
5219326F (Dialight) and HLMP-1640 (Broadcom) operate at reduced power levels. The 5219326F requires only 2mA at 1.9V with 1.6mcd output. The HLMP-1640 operates at 5V with 10mA and 1.6mcd output. These are suitable for battery-powered or low-power indicator applications.
High-Voltage Substitutes:
5219323F (Dialight) and HLMP-1641 (Broadcom) operate at elevated forward voltages of 7.5V and 12V respectively, suitable for direct integration into higher-voltage circuits without series resistor modification.
Color-Variant Substitute:
414SYGD/S530-E2 (Everlight) is a yellow-green LED at 573nm dominant wavelength with 12.5mcd brightness, 2V forward voltage, and 140° viewing angle. This part is suitable only when yellow-green color is acceptable in the application.
All listed substitutes maintain ROHS3 compliance and unlimited moisture sensitivity rating. Selection should be based on circuit voltage requirements, desired brightness level, and viewing angle specifications.
Frequently Asked Questions (FAQ)
Q: Can I use HLMP-1641 as a direct replacement for TLHG4600?
A: HLMP-1641 is mechanically and functionally compatible but requires circuit redesign. The TLHG4600 operates at 2.4V while HLMP-1641 operates at 12V. The series resistor value must be recalculated to accommodate the higher forward voltage and 13mA test current.
Q: What is the difference between diffused and clear lens transparency?
A: Diffused lenses scatter light over a wider area with reduced peak brightness, while clear lenses concentrate light with higher peak intensity in the viewing direction. The TLHG4600 uses diffused transparency. The 5219430F substitute uses clear transparency and delivers 50mcd compared to the TLHG4600's 4mcd, making it brighter but with a narrower viewing angle of 45°.
Q: Is 414SYGD/S530-E2 a suitable substitute?
A: 414SYGD/S530-E2 is mechanically compatible but produces yellow-green light at 573nm instead of green at 569nm. Use this substitute only if the application accepts yellow-green color indication. The part operates at 2V with 20mA test current and offers a wide 140° viewing angle.
Q: What viewing angle differences exist among substitutes?
A: The TLHG4600 provides 120° viewing angle. Substitutes range from 45° (5219430F, narrow viewing) to 140° (414SYGD/S530-E2, wide viewing). Narrower angles concentrate brightness in the forward direction, while wider angles distribute light over a larger area. Select based on application visibility requirements.
Q: Are all substitutes ROHS3 compliant?
A: All listed substitutes except 414SYGD/S530-E2 explicitly state ROHS3 compliance. The 414SYGD/S530-E2 RoHS status is not specified in the provided data. Verify compliance documentation with the supplier before use in regulated applications.
Q: What is the brightness difference between TLHG4600 and 5219430F?
A: The TLHG4600 delivers 4mcd at 2.4V and 10mA. The 5219430F delivers 50mcd at 2.1V and 10mA. The 5219430F is 12.5 times brighter but uses clear lens transparency instead of diffused, resulting in a narrower 45° viewing angle versus the TLHG4600's 120° angle.
Q: Can I use HLMP-1790 in a low-power application?
A: Yes. HLMP-1790 operates at 1.9V with only 2mA test current, making it suitable for battery-powered applications. It delivers 2.3mcd brightness with 50° viewing angle. This part is ideal when power consumption must be minimized.
Q: What is the height difference between TLHG4600 and substitutes?
A: The TLHG4600 has a maximum height of 6.10mm. Substitutes range from 5.55mm (151031VS06000) to 7.00mm (414SYGD/S530-E2). Verify PCB clearance requirements before selecting a substitute with different height specifications.
Q: Are Broadcom HLMP series parts interchangeable with each other?
A: Broadcom HLMP series parts share the same 3mm T-1 package and round domed lens style but differ in forward voltage, brightness, and viewing angle. HLMP-1640 (5V, 1.6mcd, 60°), HLMP-1641 (12V, 1.6mcd, 60°), and HLMP-1790 (1.9V, 2.3mcd, 50°) are not direct replacements. Circuit redesign is required when switching between these parts.
