Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C566T-RFS-CR0T0CC1 is determined by the following critical parameters:

• Color and Wavelength: Red spectrum (626–628nm dominant wavelength) for visual indication compatibility
• Lens Configuration: Diffused 5mm oval with domed top for optical consistency
• Mounting Type: Through-hole radial package for PCB assembly compatibility
• Electrical Characteristics: Forward voltage (Vf) range 2.1–2.3V and 20mA test current for circuit design compatibility
• Compliance: RoHS and REACH compliance status for regulatory alignment
• Product Status: Active status for ongoing availability

The identified substitute parts HLMP-HG74-XY0DD and HLMP-HG75-XY0DD, both manufactured by Broadcom Limited, meet these substitution criteria. Both parts operate at 2.1V forward voltage (within acceptable tolerance for red LED applications), maintain the same diffused 5mm oval lens configuration, and are RoHS3 compliant. The primary differences are mechanical height and brightness rating, which are application-dependent considerations.

Parameter Comparison

Engineering Selection Recommendations

HLMP-HG75-XY0DD is the primary substitute for C566T-RFS-CR0T0CC1. This part maintains the closest mechanical profile with a maximum height of 11.30mm, compared to the original 11.90mm. Both parts share identical electrical test conditions (20mA) and operate within compatible forward voltage ranges (2.1V vs. 2.3V). HLMP-HG75-XY0DD is ROHS3 compliant and REACH unaffected, meeting all regulatory requirements of the original part.

HLMP-HG74-XY0DD serves as a secondary substitute when mechanical height constraints permit. This part features a reduced maximum height of 7.00mm, making it suitable for space-constrained applications. Electrical compatibility remains equivalent at 2.1V forward voltage and 20mA test current. ROHS3 and REACH compliance are maintained.

Both Broadcom substitutes deliver higher brightness (2030mcd) compared to the original 1035mcd, which may require circuit-level current limiting adjustments to maintain equivalent luminous intensity in the application. Both substitutes provide wider viewing angles (100° vs. 70°), which may affect application-specific optical performance.

Frequently Asked Questions (FAQ)

Q: Can HLMP-HG74-XY0DD and HLMP-HG75-XY0DD be used interchangeably with C566T-RFS-CR0T0CC1?

A: Both Broadcom parts are electrically compatible substitutes. The primary difference is mechanical height: HLMP-HG74-XY0DD at 7.00mm maximum height and HLMP-HG75-XY0DD at 11.30mm maximum height. Selection depends on PCB layout constraints and available mounting space. The original part height is 11.90mm, making HLMP-HG75-XY0DD the closest mechanical match.

Q: What is the impact of the forward voltage difference (2.3V vs. 2.1V)?

A: The 0.2V difference is within acceptable tolerance for red LED indication circuits. Circuit designs operating at 2.3V will function with 2.1V substitutes, though current limiting resistor values may require adjustment to maintain equivalent brightness levels. The substitute parts deliver higher brightness (2030mcd vs. 1035mcd), which may necessitate increased series resistance to achieve equivalent luminous intensity.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both HLMP-HG74-XY0DD and HLMP-HG75-XY0DD are ROHS3 compliant and REACH unaffected, meeting the regulatory requirements of the original C566T-RFS-CR0T0CC1 part.

Q: How do the viewing angles differ?

A: The original C566T-RFS-CR0T0CC1 has a 70° viewing angle, while both Broadcom substitutes provide 100° viewing angles. This wider angle may affect application-specific optical performance and should be evaluated for the intended indication function.

Q: What packaging formats are available for the substitute parts?

A: HLMP-HG74-XY0DD and HLMP-HG75-XY0DD are supplied in Cut Tape (CT) packaging, whereas the original part is available in Bulk packaging. Packaging format selection depends on procurement volume and assembly process requirements.
