Engineering Selection Recommendations

For Direct Replacement (Matching Electrical Characteristics):

HLMP-K101 is the closest electrical match to SSL-LX30FT14ID, sharing identical forward voltage (1.8V nominal) and test current (20mA). Both components are ROHS3 compliant with MSL 1 rating. HLMP-K101 offers higher brightness (45mcd versus 10mcd) and slightly narrower viewing angle (60° versus 100°), making it suitable for applications requiring increased luminous intensity.

For Low-Power Applications:

HLMP-1700 and HLMP-1700-B0002 operate at 1.7V with 2mA test current, reducing power consumption significantly. These Broadcom components are Active status with extensive inventory availability (530,300 and 21,034 units respectively). The Cut Tape packaging variant (HLMP-1700-B0002) provides alternative supply chain options.

For High-Voltage Circuit Integration:

HLMP-1601 operates at 12V forward voltage with 13mA test current, designed for direct integration into higher voltage circuits without series resistor modification. This component maintains ROHS3 compliance and Active product status.

For Packaging Flexibility:

LTL-1CHE from Lite-On Inc. matches SSL-LX30FT14ID electrical specifications (2V, 20mA) with slightly higher brightness (12.6mcd) and reduced height (5.20mm). This component is ROHS3 compliant and available in bulk packaging with 16,940 units in stock.

Components to Avoid for New Designs:

4300F1LC carries "Not For New Designs" status and should not be selected for new circuit development, despite physical compatibility.

Frequently Asked Questions (FAQ)

Q: Can HLMP-1700 directly replace SSL-LX30FT14ID in existing circuits?

A: Physical replacement is possible due to identical 3mm T-1 through-hole radial form factor. However, electrical circuit modification is required. HLMP-1700 operates at 1.7V with 2mA test current versus SSL-LX30FT14ID at 2V with 20mA. Series resistor values must be recalculated for the new voltage and current specifications.

Q: What is the difference between HLMP-1700 and HLMP-1700-B0002?

A: Both parts are electrically identical (1.7V, 2mA, 2.1mcd, 635nm peak wavelength). The primary difference is packaging: HLMP-1700 is supplied in Bulk packaging, while HLMP-1700-B0002 is supplied in Cut Tape (CT) format. Selection depends on assembly process requirements and supply chain preferences.

Q: Is HLMP-K101 suitable as a substitute if brightness is critical?

A: Yes. HLMP-K101 provides 45mcd brightness compared to SSL-LX30FT14ID at 10mcd, a 4.5x increase. Forward voltage is 1.8V (versus 2V) and test current is 20mA (matching SSL-LX30FT14ID). Viewing angle is 60° versus 100°, resulting in more focused light output. This component is Active status and ROHS3 compliant.

Q: Why do some substitutes have different wavelengths?

A: Red LEDs span wavelength ranges from 623nm to 697nm depending on semiconductor material composition. SSL-LX30FT14ID operates at 635nm peak wavelength. Substitutes like HLMP-K150 (660nm) and LTL-4211N (697nm) produce visually different red hues. Wavelength selection depends on application color requirements and human perception specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. All components also have MSL 1 (Unlimited) moisture sensitivity rating, matching SSL-LX30FT14ID specifications.

Q: What is the significance of viewing angle differences?

A: SSL-LX30FT14ID provides 100° viewing angle for wide-angle indication applications. Substitutes with 50° or 60° viewing angles concentrate light output in a narrower cone, suitable for applications requiring focused indication or reduced ambient light interference. Circuit placement and optical design must account for these differences.

Q: Can LTL-4211N be used as a substitute despite different wavelength?

A: LTL-4211N operates at 697nm peak wavelength (deep red) versus SSL-LX30FT14ID at 635nm (standard red). Physical form factor is compatible (3mm T-1 through-hole radial). However, the visual color appearance differs significantly. Use only if application specifications explicitly allow deep red wavelength substitution.
