Engineering Selection Recommendations

Tier 1 - Preferred Substitutes (Highest Compatibility):

HLMP-3351-D0000 and HLMP-3351-D0002 maintain identical T-1 3/4 package geometry and radial through-hole mounting. Both are Active status, ROHS3 compliant, and REACH unaffected. Forward voltage of 1.9V is within acceptable tolerance of the 2V specification. Test current of 10mA represents a 50% reduction from the 20mA specification; applications requiring full 20mA operation must verify luminous intensity sufficiency at reduced current. Millicandela rating of 2.1mcd is lower than the 5mcd specification; circuit design must accommodate reduced brightness output.

HLMP-3351 offers improved millicandela rating of 5.4mcd, matching the luminous intensity requirement while maintaining identical package and voltage specifications. Viewing angle of 50° is narrower than the 60° specification; applications with wide viewing angle requirements should verify acceptability.

HLMP-3301-F00DD provides 5.4mcd output with 60° viewing angle matching the original specification. Forward voltage of 1.9V and test current of 10mA follow the same tolerance pattern as other Broadcom alternatives. Height of 9.19mm exceeds the 6.00mm specification; PCB clearance verification is required.

Tier 2 - Compatible Alternatives (Conditional Substitution):

5219672F (Dialight) operates at 2V forward voltage with 20mA test current, matching the electrical specification exactly. Millicandela rating of 60mcd significantly exceeds the 5mcd requirement; circuit current-limiting design must accommodate higher brightness output. Lens size of 4.75mm diameter and height of 8.21mm represent minor dimensional variations from the T-1 3/4 specification; mechanical fit verification on target PCB is required.

5219240F (Dialight) provides 6.3mcd output with 5.00mm lens diameter and T-1 3/4 equivalent form factor. Forward voltage and viewing angle specifications are not provided; electrical compatibility cannot be confirmed from available data.

5219320F (Dialight) operates at 1.8V forward voltage with 2mA test current, representing significant electrical deviation from the 2V/20mA specification. Millicandela rating of 2mcd is substantially lower than the 5mcd requirement. This part is suitable only for applications with reduced brightness and current requirements.

Tier 3 - Extended Compatibility (Limited Substitution):

HLMP-D101 (Broadcom) maintains T-1 3/4 package and radial through-hole mounting with 1.8V forward voltage and 20mA test current. Millicandela rating of 70mcd significantly exceeds the 5mcd specification; circuit design must accommodate higher brightness output. Viewing angle of 65° exceeds the 60° specification. Height of 9.19mm exceeds the 6.00mm specification; PCB clearance verification is required.

HLMP-3600-D00B2 (Broadcom) features right-angle through-hole mounting, representing a different mechanical configuration from the radial specification. Lens size and height specifications are not provided. This part is suitable only for applications permitting right-angle PCB mounting orientation.

HLMP-D150 (onsemi) is classified as Obsolete product status. Substitution is not recommended for new designs or ongoing production applications.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3351-D0000 directly replace SSL-LX5063HD without circuit modification?

A: HLMP-3351-D0000 maintains identical T-1 3/4 package geometry and radial through-hole mounting. Forward voltage of 1.9V is compatible with 2V circuit design. However, test current of 10mA is 50% lower than the 20mA specification, resulting in 2.1mcd output versus the 5mcd requirement. Circuit modification is necessary if the application requires the full 5mcd brightness specification. Viewing angle of 50° is narrower than the 60° specification; verify acceptability for the target application.

Q: What is the primary difference between HLMP-3351 and HLMP-3351-D0000?

A: Both parts share identical T-1 3/4 package, 1.9V forward voltage, and 10mA test current specifications. The primary difference is millicandela rating: HLMP-3351 delivers 5.4mcd while HLMP-3351-D0000 delivers 2.1mcd. HLMP-3351 is preferred when the application requires brightness output matching the original 5mcd specification.

Q: Can 5219672F be used as a direct substitute for SSL-LX5063HD?

A: 5219672F matches the electrical specifications exactly: 2V forward voltage and 20mA test current. Package form factor is 5mm radial through-hole, equivalent to T-1 3/4. However, millicandela rating of 60mcd significantly exceeds the 5mcd specification. Circuit current-limiting design must be verified to accommodate the higher brightness output. Lens diameter of 4.75mm and height of 8.21mm represent minor dimensional variations; mechanical fit on the target PCB must be confirmed.

Q: Why is HLMP-D150 not recommended as a substitute?

A: HLMP-D150 is classified as Obsolete product status. Substitution is not recommended for new designs or ongoing production applications. Active alternatives such as HLMP-3351-D0000, HLMP-3351, or HLMP-3301-F00DD are preferred for long-term supply assurance.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) Lens size and package format (5mm, T-1 3/4 radial preferred), (2) Mounting type (through-hole radial), (3) Forward voltage (2V nominal, 1.8V to 1.9V acceptable), (4) Test current (20mA nominal, 10mA acceptable with brightness verification), (5) Millicandela rating (5mcd minimum for equivalent brightness), (6) Viewing angle (60° preferred, 50° acceptable with application verification), (7) Product status (Active required), (8) Compliance certifications (ROHS3 compliant, REACH unaffected).

Q: Can HLMP-3600-D00B2 replace SSL-LX5063HD?

A: HLMP-3600-D00B2 features right-angle through-hole mounting, which differs from the radial configuration of SSL-LX5063HD. This part is suitable only for applications permitting right-angle PCB mounting orientation. Lens size and height specifications are not provided in the available data. Mechanical fit verification is required before substitution.

Q: What is the impact of using HLMP-3301-F00DD instead of SSL-LX5063HD?

A: HLMP-3301-F00DD maintains T-1 3/4 package, 1.9V forward voltage, and 60° viewing angle matching the original specification. Millicandela rating of 5.4mcd exceeds the 5mcd requirement. Test current of 10mA is 50% lower than the 20mA specification. Height of 9.19mm exceeds the 6.00mm specification; PCB clearance verification is required. This part is suitable when brightness output and viewing angle are critical parameters and PCB clearance permits the increased height.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the compliance status of SSL-LX5063HD. Compliance certifications are consistent across all Active status alternatives.
