Frequently Asked Questions (FAQ)
Q1: Can HLMP-4719 replace HLMP47199MP7 in all applications?
A: HLMP-4719 is the optimal direct substitute. It matches all critical parameters: 1.8V forward voltage (within 0.1V of 1.9V), 2mA test current, 2.1mcd brightness, 50° viewing angle, and 5mm T-1 3/4 yellow diffused through-hole configuration. Substitution is valid without circuit modification.
Q2: What is the difference between HLMP-3401 and HLMP-3401-E0002?
A: Both parts have identical electrical and optical specifications (2V, 10mA, 5.7mcd, 60° viewing angle, 5mm T-1 3/4 yellow diffused). The primary difference is packaging: HLMP-3401 is supplied in Bulk, while HLMP-3401-E0002 is supplied in Cut Tape (CT). Inventory availability differs significantly (2,300 pcs vs. 35,845 pcs).
Q3: Why is 5219321F listed as a substitute if the lens diameter is 4.83mm instead of 5mm?
A: The 4.83mm lens diameter is within acceptable mechanical tolerance for 5mm T-1 3/4 through-hole applications. The part maintains identical electrical specifications (1.9V, 2mA), matching millicandela rating (1.8mcd), and identical viewing angle (50°). Form factor compatibility is confirmed for standard circuit board mounting.
Q4: Can HLMP-3401 be used as a drop-in replacement for HLMP47199MP7?
A: HLMP-3401 is not a drop-in replacement. While it maintains the same lens size (5mm T-1 3/4) and yellow diffused configuration, it operates at 2V (0.1V higher) with 10mA test current (5x higher) and delivers 5.7mcd brightness (2.7x higher). Substitution requires circuit design verification to confirm the application can tolerate increased current draw and brightness. Viewing angle is also wider (60° vs. 50°).
Q5: Why are 4308H7, 5219322F, 5219327F, HLMP-3650, and HLMP-3651 not recommended as substitutes?
A: These parts fail critical compatibility criteria. 4308H7 has clear lens (not diffused), excessive brightness (140mcd), and narrow viewing angle (24°). 5219322F is 3mm size with 7.5V rating. 5219327F is green (not yellow). HLMP-3650 and HLMP-3651 operate at 5V and 12V respectively, incompatible with 1.9V circuit design. None meet the specified parameter requirements.
Q6: What is the significance of RoHS3 compliance and MSL-1 rating in substitution?
A: RoHS3 compliance ensures the substitute part meets European Union Restriction of Hazardous Substances regulations, maintaining regulatory compatibility with the original part. MSL-1 (Unlimited) moisture sensitivity rating indicates the part has no moisture sensitivity restrictions during storage and handling, matching the original HLMP47199MP7 specification. Both certifications are mandatory for valid substitution.
Q7: How does wavelength peak affect substitution eligibility?
A: The HLMP47199MP7 specifies 565nm peak wavelength. Substitute parts with 583nm peak wavelength (HLMP-3401, HLMP-3401-E0002, HLMP-3401-E00B2, 5219321F) represent a 18nm shift toward longer wavelengths. This shift is within the yellow LED spectrum range and does not prevent substitution, as both wavelengths produce visually equivalent yellow indication. However, applications requiring precise wavelength matching should verify this parameter with circuit design requirements.
Q8: What packaging options are available for recommended substitutes?
A: HLMP-4719 is supplied in Bulk packaging. 5219321F is supplied in Bulk. HLMP-3401 is supplied in Bulk. HLMP-3401-E0002 is supplied in Cut Tape (CT), suitable for automated assembly. HLMP-3401-E00B2 is supplied in Bulk. Packaging selection depends on manufacturing process requirements and volume specifications.
Q9: Are there inventory considerations when selecting a substitute?
A: Yes. HLMP-4719 has the highest inventory availability (23,019 pcs), followed by HLMP-3401-E0002 (35,845 pcs). HLMP-3401-E00B2 has 2,014 pcs, HLMP-3401 has 2,300 pcs, and 5219321F has 1,794 pcs. For applications requiring immediate availability, HLMP-4719 or HLMP-3401-E0002 are preferred.
Q10: Can viewing angle differences affect substitution validity?
A: Viewing angle differences must be evaluated within application context. HLMP47199MP7 specifies 50° viewing angle. HLMP-4719 and 5219321F maintain 50° viewing angle, ensuring direct compatibility. HLMP-3401 variants specify 60° viewing angle (10° wider), providing broader light distribution. Wider viewing angle does not prevent substitution but may alter visual indication characteristics. Applications requiring precise viewing angle should confirm this parameter with circuit design specifications.
