HLMP-CB15-RSC00 Equivalent & Substitute Parts

Part Overview

The HLMP-CB15-RSC00 is a blue LED indicator from Broadcom Limited, featuring a 5mm T-1 3/4 through-hole package with 2000mcd brightness and 472nm dominant wavelength. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain compatibility across electrical characteristics, mechanical form factor, and optical performance within the specified tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLMP-CB15-RSC00 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Blue
• Mounting Type: Through Hole
• Package Configuration: Radial
• Lens Size: 5mm form factor (T-1 3/4 or equivalent 5mm diameter)

Electrical Compatibility Range:

• Forward Voltage (Vf): 3.2V ± 0.2V (acceptable range: 3.0V to 3.4V)
• Test Current: 20mA (standard for blue LEDs)

Optical Performance:

• Wavelength - Dominant: 470nm to 472nm (blue spectrum)
• Millicandela Rating: 2000mcd minimum
• Viewing Angle: 15° to 30° (narrow to standard viewing angles)

The three substitute parts listed meet these criteria with minor variations in brightness and wavelength within acceptable engineering tolerances for blue LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

7344-15SUBC/C470/S400-A6 (Everlight Electronics)

This substitute provides direct electrical and optical equivalence with the HLMP-CB15-RSC00. Forward voltage is 3.4V (within 0.2V tolerance), and millicandela rating matches at 2000mcd. The dominant wavelength of 470nm is within the blue spectrum range. The primary consideration is lens diameter at 4.60mm versus the original 5mm, which may affect mechanical fit in applications with tight PCB spacing. This part is active and RoHS3 compliant.

WP7113QBC/D (Kingbright)

This substitute maintains the 5mm T-1 3/4 form factor and through-hole radial package, ensuring direct mechanical compatibility. Forward voltage is 3.3V (within tolerance), and height is 8.60mm (0.31mm shorter than original). Millicandela rating is elevated at 2700mcd, providing 35% greater brightness. Wavelength shift to 465nm represents a minor shift within acceptable blue LED specification ranges. This part is active and RoHS3 compliant.

WP7113QBC/G (Kingbright)

This substitute also maintains the 5mm T-1 3/4 form factor and radial package. Forward voltage is 3.3V (within tolerance). The millicandela rating of 4200mcd represents a 110% increase in brightness compared to the original part. This elevated brightness may require circuit-level current limiting adjustments to prevent over-driving. Wavelength at 465nm is consistent with the WP7113QBC/D variant. This part is active and RoHS3 compliant.

All three substitutes are classified as active products with unlimited moisture sensitivity ratings and identical export classifications, supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 7344-15SUBC/C470/S400-A6 be used as a direct drop-in replacement?

A: The 7344-15SUBC/C470/S400-A6 is electrically and optically compatible. However, the lens diameter is 4.60mm versus the original 5mm. Verify mechanical clearance in your PCB layout and component mounting fixtures before implementation.

Q: What is the brightness difference between the original part and the Kingbright substitutes?

A: The WP7113QBC/D provides 2700mcd (35% brighter), and the WP7113QBC/G provides 4200mcd (110% brighter) compared to the original 2000mcd. Circuit designs relying on specific brightness levels should be evaluated for compatibility with increased light output.

Q: Are all substitute parts RoHS compliant?

A: The Everlight 7344-15SUBC/C470/S400-A6 is RoHS3 compliant. Both Kingbright parts (WP7113QBC/D and WP7113QBC/G) are RoHS3 compliant. The original HLMP-CB15-RSC00 does not specify RoHS status but is REACH unaffected.

Q: What is the viewing angle difference, and does it matter?

A: The original part has a 15° viewing angle. The Everlight substitute has 30°, and both Kingbright substitutes have 16°. Wider viewing angles distribute light over a larger area, which may affect indicator visibility in specific mounting orientations. Evaluate based on your application's viewing requirements.

Q: Can I use the higher brightness Kingbright parts without circuit modifications?

A: The WP7113QBC/G at 4200mcd may require current limiting adjustments to prevent excessive brightness or component stress. Review your circuit's current-limiting design and test with the higher brightness part before full production implementation.

Q: Are all parts available in the same packaging quantities?

A: Packaging is listed as bulk for all substitute parts. Verify minimum order quantities and lead times with your supplier, as availability may differ from the original part's 680-piece inventory level.
