Engineering Selection Recommendations

Best Match for Direct Substitution (1.9V / 2mA Operation):

5219321F (Dialight) is the closest electrical equivalent to the HLMP47199MP93. It operates at 1.9V and 2mA, matching the original part's power requirements exactly. The millicandela rating (1.8mcd) is within 14% of the original (2.1mcd), and the viewing angle (50°) is identical. This part is in active production status with 1,794 units in stock. The 4.83mm lens diameter is slightly smaller than the 5mm T-1 3/4 specification but remains mechanically compatible for most circuit board applications.

Alternative for 2V Operation:

HLMP-3401-E00B2 (Broadcom Limited) operates at 2V with a 10mA current rating and provides 5.7mcd brightness. This part is suitable for applications where slightly higher brightness is acceptable and the circuit can accommodate 10mA current draw. It maintains the 5mm T-1 3/4 form factor and right-angle mounting configuration. With 35,845 units in stock in cut tape packaging, this part offers excellent availability.

Alternative for 5V Operation:

HLMP-3650-C00B2 (Broadcom Limited) is specified for 5V operation and requires circuit redesign if the original application operates at 1.9V. This part is suitable only for systems with 5V power supplies. It provides 2.2mcd brightness and maintains the right-angle mounting configuration. Use this part only if your circuit design supports 5V LED operation.

Not Recommended for Direct Substitution:

4308H7 (Visual Communications Company - VCC) operates at 2.2V with 20mA current and provides 140mcd brightness. The significantly higher current requirement and brightness output make this part unsuitable for direct substitution without circuit modification. The narrower viewing angle (24°) also differs from the original specification.

Compliance Status:

All substitute parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can I use 5219321F as a direct replacement for HLMP47199MP93?

A: Yes. The 5219321F matches the critical electrical parameters: 1.9V voltage rating, 2mA current, and 50° viewing angle. The millicandela rating (1.8mcd) is within acceptable tolerance of the original (2.1mcd). The lens diameter (4.83mm) is slightly smaller than the 5mm specification but remains compatible with standard 5mm circuit board mounting holes. This is the recommended substitute for 1.9V / 2mA applications.

Q: What is the difference between the HLMP-3401-E00B2 and HLMP-3650-C00B2?

A: Both parts are Broadcom Limited yellow LEDs in 5mm T-1 3/4 right-angle configuration. The primary difference is voltage rating: HLMP-3401-E00B2 operates at 2V, while HLMP-3650-C00B2 operates at 5V. The HLMP-3401-E00B2 is closer to the original part's 1.9V specification and is preferred for low-voltage applications. Choose HLMP-3650-C00B2 only if your circuit design requires 5V operation.

Q: Why is the 4308H7 not recommended as a substitute?

A: The 4308H7 requires 20mA current compared to the original part's 2mA specification. This 10-fold increase in current draw requires circuit redesign and may not be compatible with existing current-limiting resistor values. Additionally, the 140mcd brightness is significantly higher than the original 2.1mcd, which may cause visual glare or compatibility issues in indicator applications designed for low-brightness operation. The narrower 24° viewing angle also differs from the original 50° specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (5219321F, HLMP-3401-E00B2, HLMP-3650-C00B2, and 4308H7) are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original HLMP47199MP93 environmental specifications.

Q: What is the difference between right-angle and radial mounting?

A: Right-angle mounting positions the LED leads perpendicular to the circuit board surface, allowing the LED to mount flush against the board edge. Radial mounting positions the leads parallel to the board surface, requiring the LED to extend upward from the board. The original HLMP47199MP93 uses right-angle mounting. Substitute parts with radial mounting (such as standard 5219321F variants) may require mechanical adaptation or board layout modification.

Q: Can I substitute a part with different wavelength specifications?

A: The substitute parts listed operate at 583nm peak wavelength compared to the original 565nm specification. Both wavelengths fall within the yellow LED spectrum and are visually indistinguishable to the human eye. If your application requires precise wavelength matching (such as in optical sensing or color-critical applications), verify wavelength compatibility with your system requirements before substitution.

Q: What inventory levels are available for each substitute part?

A: 5219321F: 1,794 units in stock; HLMP-3401-E00B2: 35,845 units in stock (cut tape); HLMP-3650-C00B2: 949 units in stock; 4308H7: 4,869 units in stock. Verify current inventory status with your supplier before placing orders.
