Engineering Selection Recommendations

For Direct Replacement (Minimum Design Modification):

TLDR5800 (Vishay Semiconductor Opto Division) is the primary direct substitute. This part maintains the 1.8V forward voltage specification of the H-2000L, ensuring compatibility with existing circuit designs without modification. The TLDR5800 provides 2500mcd luminous intensity compared to the H-2000L's 2000mcd, representing a 25% increase in brightness within acceptable operational parameters. The wavelength specification of 648nm is within the red spectrum range and visually indistinguishable from the original 647nm. The TLDR5800 is Active status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), supporting long-term supply chain continuity.

For Applications Tolerating Forward Voltage Increase (1.8V to 2V):

7343-2SURC/H2/S400-A8 (Everlight Electronics) provides an exact 2000mcd luminous intensity match to the H-2000L. This part operates at 2V forward voltage, requiring circuit verification to confirm the 0.2V increase does not exceed design margins. The 7343-2SURC/H2/S400-A8 offers a 30° viewing angle compared to the H-2000L's 10°, providing wider light distribution. This part is Active status with ROHS3 compliance.

For Applications Requiring Higher Luminous Intensity:

333-2SURC/S400-A8 (Everlight Electronics) and 383-2SURC/S400-A6 (Everlight Electronics) provide 5000mcd and 6300mcd respectively, supporting applications requiring increased brightness. Both operate at 2V forward voltage. The 333-2SURC/S400-A8 maintains the 10° viewing angle of the H-2000L, while the 383-2SURC/S400-A6 provides a narrower 6° viewing angle. Both are Active status with ROHS3 compliance.

Compliance Considerations:

All recommended substitute parts are ROHS3 compliant and carry EAR99 ECCN classification, matching the regulatory status of the H-2000L. All substitute parts are classified as REACH Unaffected. Moisture sensitivity levels for active substitutes are specified as MSL 1 (Unlimited), supporting standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can TLDR5800 be used as a direct drop-in replacement for H-2000L?

A: Yes. The TLDR5800 maintains the 1.8V forward voltage specification and 5mm T-1 3/4 through-hole radial package of the H-2000L. No circuit modification is required. The 2500mcd luminous intensity is 25% higher than the H-2000L's 2000mcd, which is acceptable for indication applications. The 648nm wavelength is within the red spectrum and visually equivalent to the 647nm original specification.

Q: What is the impact of forward voltage differences between H-2000L (1.8V) and substitute parts operating at 2V?

A: A 0.2V increase in forward voltage requires circuit verification. For series resistor-limited designs, the higher forward voltage reduces current through the resistor, potentially decreasing LED brightness. For constant-current driver designs, the voltage difference is absorbed by the driver circuit with no impact on LED current or brightness. Verify your circuit topology before substitution.

Q: Why do some substitutes have significantly higher millicandela ratings (5000mcd to 6300mcd) compared to H-2000L (2000mcd)?

A: Higher millicandela ratings indicate greater luminous intensity. These parts are suitable for applications requiring brighter indication or longer viewing distances. If your application requires the original 2000mcd specification, select 7343-2SURC/H2/S400-A8 (2000mcd) or 383-2SURC/S530-A3 (2500mcd) instead.

Q: What is the significance of viewing angle differences (6° to 30°)?

A: Viewing angle defines the cone of light distribution. The H-2000L specifies 10°, providing a narrow, focused beam. Substitutes with 6° viewing angles provide even narrower beams suitable for precise indicator positioning. Substitutes with 30° viewing angles provide wider light distribution, suitable for applications where the LED is not directly facing the observer. Verify your optical design requirements before selecting a substitute with significantly different viewing angle.

Q: Are all substitute parts RoHS compliant?

A: All recommended substitute parts are ROHS3 compliant. The H-2000L's RoHS status is not specified in the provided data. All substitutes carry REACH Unaffected status, matching the regulatory classification of the H-2000L.

Q: What is the physical height difference between H-2000L (10.70mm) and substitutes?

A: Most substitutes are shorter (8.85mm to 8.90mm) than the H-2000L (10.70mm), except TLDR5800 (13.00mm). Verify PCB clearance and mechanical constraints in your design. Shorter substitutes may require lead bending adjustment if the original design relied on the H-2000L's specific height for positioning.

Q: Can 5219464F (Dialight) be used as a substitute?

A: 5219464F is not recommended as a primary substitute. This part operates at 2.2V forward voltage and provides only 125mcd luminous intensity, representing a 93.75% reduction compared to the H-2000L's 2000mcd. This part is suitable only for applications where significantly reduced brightness is acceptable and the higher forward voltage is compatible with circuit design.

Q: What inventory status should I consider when selecting a substitute?

A: TLDR5800 has 7632 pcs in stock, providing the highest availability among direct substitutes. 7343-2SURC/H2/S400-A8 has 889 pcs in stock. Everlight parts range from 640 to 906 pcs in stock. Verify current inventory with your supplier before finalizing design selection.
