Engineering Selection Recommendations

Direct Substitutes (Closest Compatibility):

HLMP-K101 and LTL-1CHE represent the closest functional equivalents to the SSL-LX30S54HD. Both operate at approximately 2V forward voltage with 20mA test current, matching the primary electrical characteristics of the main part. HLMP-K101 provides higher brightness output at 45mcd compared to the SSL-LX30S54HD's 10mcd, while LTL-1CHE delivers 12.6mcd brightness. Both maintain 60° viewing angle and red diffused lens characteristics. HLMP-K101 and LTL-1CHE are classified as Active product status, suitable for new design implementations.

Voltage-Compatible Alternatives:

HLMP-1700 and HLMP-1700-B0002 operate at 1.7V forward voltage with reduced test current of 2mA, suitable for applications requiring lower power consumption. These parts maintain the 3mm T-1 form factor and diffused red lens. HLMP-1700-B0002 is supplied in Cut Tape packaging, while HLMP-1700 is available in Bulk packaging. Both are Active status components.

Higher Voltage Applications:

HLMP-1600 operates at 5V forward voltage with 10mA test current, and HLMP-1601 operates at 12V forward voltage with 13mA test current. These parts address applications requiring higher supply voltages while maintaining the T-1 through-hole form factor and diffused red lens configuration.

Brightness-Optimized Alternative:

HLMP-K101 delivers 45mcd brightness, significantly higher than the SSL-LX30S54HD's 10mcd output. This part is suitable for applications requiring enhanced visibility while maintaining 2V operation and 20mA test current compatibility.

Not Recommended for New Designs:

The 4300F1LC from Visual Communications Company is classified as Not For New Designs product status and should not be selected for new circuit implementations, despite RoHS3 compliance and functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can HLMP-1700 substitute for SSL-LX30S54HD in a 2V circuit?

A: HLMP-1700 operates at 1.7V forward voltage compared to SSL-LX30S54HD's 2V specification. While the voltage difference is minimal, circuit design must account for the reduced forward voltage drop. HLMP-1700 requires only 2mA test current versus 20mA for the SSL-LX30S54HD, resulting in significantly lower power consumption. Substitution is feasible in circuits with voltage tolerance margins.

Q: What is the physical height constraint difference between SSL-LX30S54HD and substitute parts?

A: SSL-LX30S54HD has a maximum height of 5.00mm. Most substitute parts, including HLMP-1600, HLMP-1601, HLMP-1700, HLMP-K101, and LTL-4211, have maximum heights of 6.35mm or greater. LTL-1CHE has a maximum height of 5.20mm, representing the closest physical match. Applications with strict height constraints must verify clearance before substitution.

Q: Which substitute part provides the closest brightness match to SSL-LX30S54HD?

A: LTL-1CHE delivers 12.6mcd brightness, closest to the SSL-LX30S54HD's 10mcd rating. HLMP-K101 provides 45mcd, significantly higher output. HLMP-1600, HLMP-1601, HLMP-1700, HLMP-K150, and LTL-4211 all deliver 2mcd or lower brightness levels. Brightness selection depends on application visibility requirements.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts are RoHS3 compliant, matching the SSL-LX30S54HD's regulatory status. This ensures compatibility with RoHS3-regulated applications and supply chains.

Q: What packaging options are available for substitute parts?

A: HLMP-1700-B0002 and HLMP-K150-C0002 are supplied in Cut Tape (CT) packaging. All other substitute parts are supplied in Bulk packaging. Packaging selection depends on assembly process requirements and inventory management preferences.

Q: Which substitute parts are classified as Active product status?

A: All substitute parts except 4300F1LC are classified as Active product status. HLMP-1600, HLMP-1601, HLMP-1700, HLMP-1700-B0002, HLMP-K101, HLMP-K150, HLMP-K150-C0002, LTL-1CHE, and LTL-4211 are suitable for new design implementations. The 4300F1LC is classified as Not For New Designs and should not be selected for new applications.

Q: How does viewing angle affect substitution decisions?

A: SSL-LX30S54HD has a 60° viewing angle. Substitute parts vary between 40° and 60°. HLMP-1700, HLMP-1700-B0002, and 4300F1LC have 50° viewing angles, while LTL-4211 has a 40° viewing angle. Narrower viewing angles concentrate light output in a smaller cone, affecting visibility from off-axis positions. Application requirements determine acceptable viewing angle ranges.

Q: What is the wavelength difference between SSL-LX30S54HD and substitute parts?

A: SSL-LX30S54HD has a peak wavelength of 700nm. Substitute parts range from 635nm to 697nm. HLMP-1700 and related Broadcom parts operate at 635nm, HLMP-K101 at 645nm, HLMP-K150 at 660nm, and LTL-4211 at 697nm. Wavelength differences affect perceived color intensity and may impact human perception in visual indication applications.
