Part Overview

The AM27EC09 is a red surface-mount LED manufactured by Kingbright, designed for indication applications in discrete 2-SMD Z-Bend configuration. This component operates at 2V forward voltage with 100mcd brightness rating and features a clear, domed lens with 1.78mm diameter. The part maintains active product status with full RoHS3 compliance and REACH unaffected certification.

Substitute parts become necessary when the AM27EC09 reaches end-of-life status, inventory depletion occurs, or supply chain constraints limit availability. The substitute components listed below maintain functional compatibility within the specified electrical and mechanical parameters for red LED indication applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the AM27EC09 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Red
• Lens Transparency: Clear
• Mounting Type: Surface Mount
• Package Configuration: 2-SMD, Z-Bend
• Lens Style: Round with Domed Top
• RoHS3 Compliance: Required

Secondary Compatibility Parameters:

• Forward Voltage (Vf): 1.7V to 2V range
• Millicandela Rating: 40mcd to 100mcd range
• Lens Size: 1.70mm to 1.78mm diameter
• Physical Dimensions: Height within 2.90mm to 2.92mm
• Wavelength - Dominant: 625nm to 626nm range

The substitute parts CMD95-21SRCTR10 and HLMP-6305-L0031 meet these criteria within acceptable engineering tolerances for red LED indication circuits. Both maintain the 2-SMD Z-Bend package configuration, clear lens transparency, and surface-mount compatibility required for direct board-level substitution.

Engineering Selection Recommendations

AM27EC09 (Kingbright) - Primary Selection

The AM27EC09 maintains active product status with established supply availability (1148 pcs in stock). This component is the preferred choice for new designs and ongoing production due to its active lifecycle status and full compliance certifications.

HLMP-6305-L0031 (Broadcom Limited) - Recommended Substitute

The HLMP-6305-L0031 is the primary substitute option. It maintains active product status with superior inventory availability (12598 pcs in stock). Physical dimensions align within tolerance (2.08mm L x 2.21mm W vs. 2.21mm L x 2.21mm W), and height matches at 2.92mm. Forward voltage operates at 1.8V, within the acceptable range for red LED indication circuits. Wavelength - Dominant at 626nm closely matches the 625nm specification. Both components carry ROHS3 compliance and REACH unaffected certification. The improved moisture sensitivity level (2A vs. 3) provides enhanced reliability in storage and field conditions.

CMD95-21SRCTR10 (Visual Communications Company - VCC) - Secondary Substitute

The CMD95-21SRCTR10 carries obsolete product status, limiting its suitability for new applications. However, it remains available in high inventory (2679 pcs). Forward voltage at 1.7V operates within acceptable parameters. Millicandela rating matches at 100mcd. Physical dimensions (2.20mm L x 2.10mm W, 2.90mm height) remain compatible with board-level placement. ROHS3 compliance and REACH unaffected certification are maintained. The improved moisture sensitivity level (2 vs. 3) offers enhanced environmental protection. Selection of this part should be limited to legacy system maintenance or applications where existing inventory must be consumed.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-6305-L0031 directly replace the AM27EC09 in existing circuit designs?

A: Yes. Both components share identical package configuration (2-SMD, Z-Bend), mounting type (Surface Mount), and lens specifications (Clear, Round with Domed Top, 1.78mm diameter). Forward voltage difference (1.8V vs. 2V) is within acceptable tolerance for standard LED indication circuits. Circuit current-limiting resistor values may require minor adjustment based on the specific application's brightness requirements, as the HLMP-6305-L0031 operates at 10mA test current versus 20mA for the AM27EC09.

Q: What are the key differences between the AM27EC09 and CMD95-21SRCTR10?

A: Primary differences include product status (Active vs. Obsolete), forward voltage (2V vs. 1.7V), and lens size (1.78mm vs. 1.70mm diameter). Both maintain 100mcd brightness rating and 2-SMD Z-Bend package compatibility. The CMD95-21SRCTR10 features a wider viewing angle (25° vs. 20°). Obsolete status of the CMD95-21SRCTR10 restricts its use to legacy applications or inventory consumption scenarios.

Q: How do viewing angle differences affect substitution compatibility?

A: The AM27EC09 specifies 20° viewing angle, while substitutes offer 25° (CMD95-21SRCTR10) and 28° (HLMP-6305-L0031). Wider viewing angles increase light distribution across a broader field. For direct replacement in existing designs, wider viewing angles provide equal or improved performance. Applications requiring narrow-angle indication should evaluate the specific optical requirements before substitution.

Q: Are there moisture sensitivity considerations for long-term storage?

A: Yes. The AM27EC09 carries MSL 3 (168 Hours), while both substitutes offer improved ratings: CMD95-21SRCTR10 at MSL 2 (1 Year) and HLMP-6305-L0031 at MSL 2A (4 Weeks). Lower MSL values indicate reduced moisture absorption and extended shelf life. For applications involving extended storage or high-humidity environments, the substitute parts provide enhanced reliability.

Q: What is the impact of wavelength differences on visual appearance?

A: The AM27EC09 specifies 625nm dominant wavelength (627nm peak), while HLMP-6305-L0031 operates at 626nm dominant (635nm peak), and CMD95-21SRCTR10 at 660nm peak. These variations fall within the red spectrum and produce visually similar indication colors. Wavelength differences of 1-2nm are imperceptible to human vision in indication applications. The 660nm peak of CMD95-21SRCTR10 may appear slightly more orange-red compared to the pure red of the other components.

Q: Can brightness differences affect circuit performance?

A: The AM27EC09 and CMD95-21SRCTR10 both specify 100mcd, while HLMP-6305-L0031 operates at 40mcd. For standard indication applications, 40mcd remains sufficient for visual feedback. Applications requiring maximum brightness should retain the AM27EC09 or CMD95-21SRCTR10. Circuit current-limiting resistor values determine actual brightness output; resistor adjustment can compensate for brightness differences if required by the application.
