HLMP-3568 Equivalent & Substitute Parts

Part Overview

The HLMP-3568 is a green LED indicator with a 5mm T-1 3/4 through-hole radial package, manufactured by Broadcom Limited. This component operates at 2.1V forward voltage with a 10.6mcd brightness rating and 569nm dominant wavelength. The product is currently active and widely used in indication applications requiring discrete LED solutions.

Substitute parts become necessary when the primary component experiences supply constraints, inventory limitations, or when design requirements permit alternative optical or mechanical characteristics within acceptable tolerances. The following parts maintain electrical compatibility while offering variations in lens transparency, brightness output, and physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLMP-3568 is determined by the following mandatory parameters:

• Color: Green (all substitutes must be green)
• Lens Size: 5mm, T-1 3/4 (physical form factor requirement)
• Voltage - Forward (Vf): 2.1V (electrical compatibility)
• Current - Test: 10mA (operational current specification)
• Mounting Type: Through Hole (assembly compatibility)
• Package / Case: Radial (circuit board interface)

The identified substitute parts LTL-4233 and SLR-56MG3F meet all mandatory electrical and mechanical parameters. Variations in lens transparency (diffused vs. clear), millicandela rating, viewing angle, and physical height are permitted within the scope of substitution, as these characteristics do not prevent functional replacement in indication applications.

Parameter Comparison

Engineering Selection Recommendations

LTL-4233 (Lite-On Inc.): This substitute maintains full electrical compatibility with the HLMP-3568 while offering increased brightness (19mcd vs. 10.6mcd) and diffused lens transparency. The component is ROHS3 compliant and currently active. Physical height increases to 8.60mm maximum. This part is suitable for applications where higher luminous intensity or diffused light distribution is acceptable.

SLR-56MG3F (Rohm Semiconductor): This substitute meets all electrical and mechanical requirements with 16mcd brightness and diffused lens transparency. The dominant wavelength shifts to 572nm, within the green spectrum range. However, this component carries a "Not For New Designs" product status designation, indicating it is in mature or declining production phase. Physical height reaches 8.90mm maximum. This part should be considered only for legacy system maintenance or when supply of active alternatives is unavailable.

Frequently Asked Questions (FAQ)

Q: Can LTL-4233 replace HLMP-3568 in existing designs? A: Yes. Both components share identical forward voltage (2.1V), test current (10mA), lens size (5mm T-1 3/4), and radial through-hole package. The primary differences are lens transparency (diffused vs. clear) and brightness output (19mcd vs. 10.6mcd). Verify that the application tolerates increased luminous intensity and diffused light distribution.

Q: What is the impact of the height difference between HLMP-3568 and substitute parts? A: HLMP-3568 has a maximum height of 6.35mm, while LTL-4233 reaches 8.60mm and SLR-56MG3F reaches 8.90mm. These differences may affect circuit board layout, component clearance, and enclosure fit. Confirm mechanical compatibility before substitution.

Q: Why is SLR-56MG3F marked "Not For New Designs"? A: This product status indicates the component is no longer recommended for new circuit designs. It may have limited future availability or reduced manufacturer support. Use this part only for replacement in existing systems where supply of active alternatives is constrained.

Q: Are all substitute parts RoHS3 compliant? A: Yes. HLMP-3568, LTL-4233, and SLR-56MG3F are all ROHS3 compliant, meeting environmental and hazardous substance restrictions.

Q: How do wavelength differences affect substitution? A: HLMP-3568 and LTL-4233 both have 569nm dominant wavelength. SLR-56MG3F operates at 572nm. Both wavelengths fall within the green spectrum and are visually indistinguishable in most indication applications. Verify wavelength requirements if the application involves color-critical or spectral-sensitive functions.
