Selection Priority Based on Product Status and Compliance:

All substitute parts listed are active products with RoHS3 compliance (where specified), ensuring long-term availability and regulatory compliance. The DG5304X obsolete status necessitates transition to active alternatives. Selection should prioritize:

Electrical compatibility (forward voltage within ±0.3V without circuit modification)
Wavelength match (525nm ±5nm for green indication)
Viewing angle suitability (application-dependent)
Brightness compatibility (circuit current limiting capability)
Inventory availability for production volume requirements

Frequently Asked Questions (FAQ)

Q: Can I directly replace DG5304X with 333-2SUGC/C525 without circuit modification?

A: Yes, 333-2SUGC/C525 has identical forward voltage (3.5V) and wavelength (525nm). However, the higher brightness (2000mcd vs 1000mcd) may require verification that the circuit current-limiting resistor accommodates increased light output. The narrower viewing angle (10° vs 25°) must be evaluated against application visibility requirements.

Q: What is the difference between the Broadcom HLMP-CM series parts?

A: All Broadcom HLMP-CM series parts share identical wavelength (525nm) and similar forward voltage (3.1-3.2V). They differ in brightness rating and viewing angle: HLMP-CM1A-560DD (60500mcd, 15°), HLMP-CM1G-350DD (43000mcd, 15°), HLMP-CM2A-230DD (28000mcd, 23°), HLMP-CM3A-Z10DD (16500mcd, 30°), and HLMP-CM3A-Z1CDD (16500mcd, 30°). Selection depends on required brightness and viewing angle for the specific application.

Q: Why do some substitutes have significantly higher brightness ratings?

A: Brightness (millicandela rating) depends on LED chip design and lens optics. Higher brightness parts require circuit current limiting adjustment to prevent excessive power dissipation and premature failure. Applications requiring standard brightness should use parts with mcd ratings closer to the original 1000mcd specification.

Q: Can I use 5219947F (Dialight) as a substitute if my circuit is designed for 3.5V forward voltage?

A: 5219947F has forward voltage 3.8V, which is 0.3V higher than the original 3.5V specification. This requires circuit verification to ensure the current-limiting resistor provides adequate voltage drop. The higher voltage may reduce circuit current slightly, affecting brightness output. Circuit simulation or testing is recommended before production implementation.

Q: What does the viewing angle difference mean for my application?

A: Viewing angle determines the cone of light emission. DG5304X has 25° viewing angle (relatively wide). Narrower angles (6-15°) concentrate light in a focused beam, suitable for direct viewing positions. Wider angles (30°) distribute light over a broader area, suitable for applications where the LED is viewed from multiple angles. Selection depends on the physical mounting location and viewing geometry.

Q: Are all substitute parts RoHS3 compliant?

A: Most active substitute parts listed include RoHS3 compliance certification. Broadcom Limited parts explicitly state RoHS3 compliance. Dialight 5219465F and 5219947F are RoHS3 compliant. Everlight Electronics parts 383-2SUGC/S400-A4 specifies RoHS3 compliance. Verify compliance documentation for specific procurement requirements.

Q: What is the maximum height constraint for PCB mounting?

A: DG5304X has maximum height 8.80mm. All substitute parts have maximum height 8.90-9.65mm. Most Everlight and Broadcom parts are 8.90mm (within 0.1mm tolerance). Dialight 5219947F reaches 9.65mm maximum. Verify PCB clearance envelope to ensure substitute parts fit within design constraints, particularly for applications with height-restricted mounting areas.

Q: Can I use yellow-green substitutes (383-2SYGC/S530-E2 or 5219465F) in place of green?

A: Yellow-green parts (573nm and 565nm wavelength) represent significant color shift from green (525nm). These are suitable only if the application can functionally accept yellow-green indication instead of green. Forward voltage is significantly lower (2.0V and 2.3V respectively), requiring substantial circuit redesign. Brightness is also reduced (320mcd and 120mcd). Use only if application requirements explicitly allow color substitution.

Q: Which substitute offers the best inventory availability?

A: HLMP-CM1G-350DD (Broadcom Limited) has the highest inventory with 13534 units in stock. This part offers excellent availability for high-volume production requirements. Alternative high-availability options include 5219465F (Dialight, 2623 units) and HLMP-CM3A-Z10DD (Broadcom, 2100 units).

Q: What circuit modifications are needed for Broadcom HLMP-CM parts with 3.2V forward voltage?

A: Broadcom HLMP-CM parts have forward voltage 3.1-3.2V, compared to DG5304X at 3.5V. This 0.3-0.4V reduction requires circuit verification. If the original circuit uses a fixed current-limiting resistor, the lower forward voltage will increase circuit current slightly (approximately 5-10% depending on resistor value and supply voltage). Recalculate the current-limiting resistor value using Ohm's law: R = (Vsupply - Vf) / Iled, where Iled is the desired LED current (typically 20mA). Alternatively, if the circuit uses a current-limiting IC, no modification may be required.
