Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on parameter compatibility with the SSL-LX3064ID:

Direct Substitutes maintain electrical and optical parameters within acceptable tolerance ranges, allowing drop-in replacement without circuit modification:

Forward voltage within ±0.3V of 2V specification
Test current at or near 20mA
Millicandela rating at or above 40mcd
Peak wavelength at 635nm
Viewing angle at 60°
Through-hole radial mounting
3mm T-1 lens form factor

Similar Alternatives share the same form factor, mounting type, and lens size but operate at different electrical parameters. These require circuit design verification before substitution:

Forward voltage range: 1.7V to 12V
Test current range: 1mA to 13mA
Millicandela rating: 1.8mcd to 2.1mcd
Peak wavelength: 626nm to 660nm
Viewing angle: 50° to 60°

All substitute parts listed maintain ROHS3 compliance, MSL Level 1 rating, and through-hole radial package configuration.

Engineering Selection Recommendations

Direct Substitution (No Circuit Modification Required):

SSL-LX3054ID and SSL-LX3054LID are direct electrical and optical equivalents to SSL-LX3064ID. Both parts share identical forward voltage (2V), test current (20mA), brightness (40mcd), peak wavelength (635nm), and viewing angle (60°). The primary difference is reduced maximum height (5.25mm versus 6.00mm), which is acceptable for most through-hole applications where vertical clearance is not constrained. Both parts are manufactured by Lumex, maintain ROHS3 compliance, and are in active production status. SSL-LX3054LID offers higher inventory availability (11007 units) compared to SSL-LX3064ID (732 units).

Conditional Substitution (Circuit Design Verification Required):

LTL-1CHE (Lite-On Inc.) matches the SSL-LX3064ID electrical specification (2V forward voltage, 20mA test current) and optical characteristics (635nm peak wavelength, 60° viewing angle). However, the brightness rating is significantly lower at 12.6mcd compared to 40mcd. This part is suitable only for applications where reduced brightness is acceptable or where current-limiting resistor values can be adjusted. The part is in active production and ROHS3 compliant.

Not Recommended for New Designs:

4300F1LC (VCC) is marked "Not For New Designs" and exhibits substantial parameter deviations: 1.8V forward voltage, 2mA test current, and 1.8mcd brightness. This part should not be selected for new circuit designs.

Alternative Voltage Platforms (Requires Circuit Redesign):

HLMP-1600, HLMP-1601, HLMP-1700, HLMP-1700-B0002, HLMP-K150, and HLMP-K150-C0002 (Broadcom Limited) operate at different forward voltages (1.7V, 5V, or 12V) and reduced brightness levels (1.8mcd to 2.1mcd). These parts are suitable only when circuit design permits voltage platform changes and reduced brightness is acceptable. All Broadcom alternatives are in active production and ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX3054ID replace SSL-LX3064ID without any circuit changes?

A: Yes. SSL-LX3054ID is electrically and optically identical to SSL-LX3064ID. Both operate at 2V forward voltage with 20mA test current and 40mcd brightness. The only difference is maximum height (5.25mm versus 6.00mm), which does not affect circuit function in standard through-hole applications.

Q: What is the difference between SSL-LX3054ID and SSL-LX3054LID?

A: Both parts are electrically and optically identical. The difference is packaging: SSL-LX3054ID is supplied in bulk packaging, while SSL-LX3054LID is supplied in cut tape (CT) packaging. Select based on assembly process requirements.

Q: Can I use LTL-1CHE as a direct replacement?

A: LTL-1CHE shares the same electrical specification (2V, 20mA) and optical wavelength (635nm) as SSL-LX3064ID. However, brightness is significantly lower at 12.6mcd versus 40mcd. Substitution is possible only if reduced brightness is acceptable for the application or if current-limiting resistor values are adjusted to increase operating current.

Q: Why are Broadcom HLMP series parts listed as alternatives rather than direct substitutes?

A: Broadcom HLMP series parts operate at different forward voltages (1.7V, 5V, or 12V) and have significantly lower brightness ratings (1.8mcd to 2.1mcd) compared to SSL-LX3064ID (2V, 40mcd). These parts require circuit redesign to accommodate different voltage platforms and are suitable only when application requirements permit these parameter changes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this reference maintain ROHS3 compliance and MSL Level 1 rating, matching the environmental and regulatory status of SSL-LX3064ID.

Q: Which substitute part has the highest inventory availability?

A: HLMP-1700 (Broadcom) has the highest inventory at 530,300 units. However, this part requires circuit redesign due to different electrical parameters (1.7V forward voltage, 2mA test current, 2.1mcd brightness). For direct substitution without circuit changes, SSL-LX3054ID offers the highest availability at 28,630 units.

Q: Can I use HLMP-K150 if my circuit operates at 1.7V?

A: HLMP-K150 is electrically compatible with 1.7V circuits. However, the brightness is significantly lower (2mcd versus 40mcd), and the peak wavelength is shifted to 660nm compared to 635nm. Substitution is possible only if reduced brightness and wavelength shift are acceptable for the application.

Q: What is the significance of the "Not For New Designs" status on 4300F1LC?

A: Parts marked "Not For New Designs" are in end-of-life status and should not be selected for new circuit designs. VCC 4300F1LC should be avoided in favor of active production alternatives.
