CMC01Y LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The CMC01Y is a yellow circuit board indicator LED manufactured by Visual Communications Company (VCC) in the CMC series. This component is a single yellow LED with clear lens, rated for 2.1V forward voltage and 20mA operating current, designed for through-hole right-angle mounting applications. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance requirements. The CMC01Y delivers 60 millicandela brightness with a 30-degree viewing angle, suitable for standard indicator applications requiring moderate luminous intensity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMC01Y is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Yellow
• Mounting Type: Through Hole, Right Angle
• Configuration: Single LED
• Wavelength Range: 565nm peak (acceptable range 560-590nm for yellow LEDs)
• Forward Voltage: 2.1V nominal (acceptable range 1.8V-2.1V for yellow LEDs)
• Operating Current: 20mA or lower
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The substitute parts identified (HLMP-1440-H00A2 and HLMP-4719-A00B2) meet the core mechanical and electrical requirements for direct substitution in through-hole right-angle mounting applications. Both substitutes are manufactured by Broadcom Limited, an active product line manufacturer, and maintain full regulatory compliance with ROHS3 and REACH standards.

Parameter Comparison

Engineering Selection Recommendations

HLMP-1440-H00A2 (Primary Substitute)

The HLMP-1440-H00A2 is the closest electrical and mechanical equivalent to the CMC01Y. This Broadcom Limited component maintains identical forward voltage (2.1V) and operating current (20mA) specifications, ensuring direct circuit compatibility without modification. The wavelength peak of 583nm falls within acceptable yellow LED parameters and produces comparable visual output. The 45 millicandela rating is slightly lower than the CMC01Y (60mcd), representing a 25% reduction in luminous intensity. The 24-degree viewing angle is narrower than the original 30-degree specification. This substitute is suitable for applications where the slightly reduced brightness and narrower viewing angle are acceptable. The HLMP-1440-H00A2 is actively manufactured and maintains full ROHS3 and REACH compliance.

HLMP-4719-A00B2 (Secondary Substitute)

The HLMP-4719-A00B2 is an alternative substitute with different electrical characteristics. This component operates at 1.8V forward voltage and 2mA operating current, representing significant reductions from the CMC01Y specifications. The 2.1 millicandela rating is substantially lower (96.5% reduction from 60mcd), making this substitute suitable only for low-brightness indicator applications. The 50-degree viewing angle exceeds the original specification. The diffused, tinted lens differs from the clear lens of the CMC01Y, affecting light transmission characteristics. This substitute requires circuit redesign to accommodate the lower voltage and current requirements and is appropriate only for applications where reduced brightness is acceptable or beneficial. The HLMP-4719-A00B2 is actively manufactured with full regulatory compliance.

Compliance Status

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the obsolete CMC01Y. Both are available in bulk packaging with substantial inventory levels (787 and 9501 units respectively).

Frequently Asked Questions (FAQ)

Q: Can the HLMP-1440-H00A2 be used as a direct replacement for the CMC01Y without circuit modifications?

A: The HLMP-1440-H00A2 maintains identical forward voltage (2.1V) and operating current (20mA) specifications as the CMC01Y, allowing direct substitution in existing circuits without modification. The component is mechanically compatible with through-hole right-angle mounting. However, the reduced millicandela rating (45mcd versus 60mcd) and narrower viewing angle (24° versus 30°) should be evaluated for specific application requirements.

Q: What are the key differences between the two substitute options?

A: The HLMP-1440-H00A2 maintains the original electrical specifications (2.1V, 20mA) with comparable brightness output, while the HLMP-4719-A00B2 operates at significantly lower voltage (1.8V) and current (2mA) with substantially reduced brightness (2.1mcd). The HLMP-1440-H00A2 features a clear lens matching the CMC01Y, while the HLMP-4719-A00B2 uses a diffused, tinted lens. Selection depends on whether the application requires maintained electrical specifications or can accommodate lower power operation.

Q: Are both substitute parts RoHS and REACH compliant?

A: Yes, both HLMP-1440-H00A2 and HLMP-4719-A00B2 are ROHS3 compliant and REACH unaffected, matching the regulatory status of the CMC01Y.

Q: What is the impact of the wavelength difference between the CMC01Y (565nm) and HLMP-1440-H00A2 (583nm)?

A: Both wavelengths fall within the yellow LED spectrum. The CMC01Y peak wavelength of 565nm represents a more green-shifted yellow, while the HLMP-1440-H00A2 at 583nm represents a more orange-shifted yellow. The visual difference is minimal for standard indicator applications, though color-critical applications should evaluate the specific wavelength requirements.

Q: Can the HLMP-4719-A00B2 be used in circuits designed for the CMC01Y?

A: The HLMP-4719-A00B2 requires circuit redesign due to different electrical specifications (1.8V versus 2.1V, 2mA versus 20mA). Direct substitution without circuit modification will result in incorrect LED operation. This component is suitable only for applications where lower power consumption and reduced brightness are acceptable or required.

Q: What mounting compatibility exists between these parts?

A: All three components (CMC01Y, HLMP-1440-H00A2, and HLMP-4719-A00B2) feature through-hole right-angle mounting, ensuring mechanical compatibility with existing PCB layouts and connector designs.

Q: How do the viewing angles compare across these components?

A: The CMC01Y provides a 30-degree viewing angle, the HLMP-1440-H00A2 provides 24 degrees, and the HLMP-4719-A00B2 provides 50 degrees. Applications requiring wide-angle visibility should consider the HLMP-4719-A00B2, while applications with directional viewing requirements may prefer the narrower angles of the CMC01Y or HLMP-1440-H00A2.
