SSL-LX3064LID Equivalent & Substitute Parts

Part Overview

The SSL-LX3064LID is a red diffused LED indicator manufactured by Lumex Opto/Components Inc., designed for through-hole mounting applications. This T-1 form factor LED operates at 2V forward voltage with a 40mcd brightness rating and 635nm peak wavelength. The component is ROHS3 compliant and currently in active production status with 892 units in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges. Alternative models may be required due to inventory availability, packaging preferences, or specific application voltage requirements.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility with the SSL-LX3064LID:

Direct Substitutes maintain identical or near-identical electrical parameters (forward voltage, test current, brightness, wavelength) and mechanical form factor. These parts can replace the main part without circuit modification:

SSL-LX3054ID and SSL-LX3054LID (Lumex Opto/Components Inc.) - Same manufacturer, identical electrical specifications, same T-1 form factor, height variance within acceptable range (5.25mm vs 6.00mm)

Similar Substitutes share the same T-1 form factor, red color, and through-hole mounting but differ in one or more electrical parameters. These require circuit evaluation before substitution:

Forward voltage variations (1.7V to 12V)
Brightness variations (1.8mcd to 2.1mcd)
Current test variations (1mA to 13mA)
Wavelength variations (626nm to 640nm)
Viewing angle variations (50° to 60°)

All substitute parts maintain ROHS3 compliance, MSL Level 1, and REACH unaffected status consistent with the main part.

Engineering Selection Recommendations

Direct Substitution (No Circuit Modification Required):

SSL-LX3054ID and SSL-LX3054LID are direct electrical equivalents to SSL-LX3064LID. Both parts maintain identical forward voltage (2V), test current (20mA), brightness (40mcd), wavelength (635nm), and viewing angle (60°). The height difference (5.25mm vs 6.00mm) represents a reduction that does not impact PCB clearance in standard applications. Both parts are ROHS3 compliant and in active production status. SSL-LX3054LID offers higher inventory availability (11,007 units) compared to the main part (892 units).

Conditional Substitution (Circuit Evaluation Required):

HLMP-1700 and HLMP-1700-B0002 (Broadcom Limited) operate at 1.7V forward voltage with significantly reduced test current (2mA vs 20mA). These parts are suitable only for applications where the circuit can accommodate lower operating current and voltage. Both are in active production status with ROHS3 compliance. HLMP-1700-B0002 is available in Cut Tape packaging for automated assembly.

HLMP-K150 and HLMP-K150-C0002 (Broadcom Limited) operate at 1.7V with 1mA test current and feature a 660nm peak wavelength (vs 635nm). These parts are suitable for low-power indicator applications where the slightly longer wavelength is acceptable. Both are in active production status with ROHS3 compliance.

HLMP-1600 (Broadcom Limited) operates at 5V forward voltage and is suitable for higher-voltage circuit applications. This part is in active production status with ROHS3 compliance.

HLMP-1601 (Broadcom Limited) operates at 12V forward voltage and is suitable for high-voltage circuit applications. This part is in active production status with ROHS3 compliance.

Not Recommended for New Designs:

4300F1LC (Visual Communications Company - VCC) is marked "Not For New Designs" and should not be selected for new applications despite electrical compatibility considerations.

LTL-1CHE (Lite-On Inc.) operates at 2V with 20mA test current but provides only 12.6mcd brightness, significantly lower than the 40mcd rating of SSL-LX3064LID. This part is suitable only for applications where reduced brightness is acceptable.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX3054LID directly replace SSL-LX3064LID without any circuit changes?

A: Yes. SSL-LX3054LID is electrically identical to SSL-LX3064LID with matching forward voltage (2V), test current (20mA), brightness (40mcd), and wavelength (635nm). The height difference (5.25mm vs 6.00mm) does not affect standard PCB applications. Both parts are ROHS3 compliant and in active production.

Q: What is the key difference between direct substitutes and similar substitutes?

A: Direct substitutes (SSL-LX3054ID, SSL-LX3054LID) maintain identical electrical parameters and require no circuit modification. Similar substitutes differ in forward voltage, test current, brightness, or wavelength and require circuit evaluation before use.

Q: Can I use HLMP-1700 in place of SSL-LX3064LID?

A: HLMP-1700 operates at 1.7V with 2mA test current, significantly different from SSL-LX3064LID (2V, 20mA). Substitution requires circuit redesign to accommodate the lower voltage and current specifications. The brightness is also reduced (2.1mcd vs 40mcd).

Q: What is the difference between HLMP-K150 and HLMP-K150-C0002?

A: Both parts are electrically identical (1.7V, 1mA, 2mcd, 660nm). The difference is packaging: HLMP-K150 is supplied in Bulk packaging, while HLMP-K150-C0002 is supplied in Cut Tape (CT) packaging for automated assembly equipment.

Q: Why is 4300F1LC listed as "Not For New Designs"?

A: 4300F1LC carries a "Not For New Designs" product status designation, indicating the manufacturer has discontinued active support for this part in new applications. New designs should use parts with "Active" status.

Q: Can I use HLMP-1600 or HLMP-1601 in a 2V circuit?

A: No. HLMP-1600 requires 5V and HLMP-1601 requires 12V forward voltage. These parts are designed for higher-voltage applications and cannot operate in a 2V circuit without external voltage regulation.

Q: What is the brightness difference between SSL-LX3064LID and LTL-1CHE?

A: SSL-LX3064LID provides 40mcd brightness while LTL-1CHE provides 12.6mcd brightness. LTL-1CHE is approximately 68% dimmer and is suitable only for applications where reduced brightness is acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, MSL Level 1, and REACH unaffected status consistent with SSL-LX3064LID.

Q: What viewing angle options are available among the substitutes?

A: Two viewing angles are available: 60° (SSL-LX3064LID, SSL-LX3054ID, SSL-LX3054LID, HLMP-1600, HLMP-1601, HLMP-K150, HLMP-K150-C0002, LTL-1CHE) and 50° (4300F1LC, HLMP-1700, HLMP-1700-B0002). The 60° viewing angle matches the main part specification.
