Equivalent & Substitute Parts for AM27CGCK03

Part Overview

The AM27CGCK03 is an active green LED indication component manufactured by Kingbright, designed for surface mount applications. This discrete 2-SMD Gull Wing package LED operates at a forward voltage of 2.1V and delivers 600mcd luminous intensity at 20mA test current. The component features a clear, domed round lens with 1.78mm diameter and 570nm dominant wavelength output.

Substitute parts are identified to provide alternative sourcing options when the primary component becomes unavailable or when inventory constraints require component flexibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM27CGCK03 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Green
• Lens Transparency: Clear
• Mounting Type: Surface Mount
• Package Configuration: 2-SMD, Gull Wing
• Peak Wavelength: 574nm
• Test Current: 20mA
• RoHS3 Compliance: Required

Secondary Tolerance Parameters:

• Forward Voltage (Vf): 2.1V nominal (tolerance range allows 2.2V)
• Millicandela Rating: 600mcd (substitutes may vary within application requirements)
• Lens Size: 1.78mm diameter (minor dimensional variations acceptable)
• Viewing Angle: 20° (substitutes may differ)

The SSL-LXA228SUGCTR11 qualifies as a substitute based on matching primary criteria across color, transparency, mounting type, package configuration, wavelength, and compliance status. Secondary parameter variations are within acceptable engineering tolerances for green LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

AM27CGCK03 (Kingbright) is the primary component specification. This part maintains active product status with ROHS3 compliance and REACH unaffected designation, confirming regulatory alignment for current manufacturing standards.

SSL-LXA228SUGCTR11 (Lumex Opto/Components Inc.) is qualified as an equivalent substitute under the following conditions:

• Both components share identical package configuration (2-SMD, Gull Wing) and mounting methodology (Surface Mount)
• Both deliver peak wavelength output at 574nm with clear lens transparency for green indication applications
• Forward voltage differential (2.1V vs. 2.2V) is within standard LED circuit design tolerance and does not require circuit modification
• Both components maintain ROHS3 compliance and REACH unaffected status
• Millicandela rating reduction (600mcd to 200mcd) and viewing angle increase (20° to 25°) represent secondary parameter variations that do not affect functional compatibility in standard indication applications
• Dimensional variations (length, width, height) are minor and do not impact PCB layout or mechanical assembly

Selection between these components should be based on availability, lead time, and cost considerations, as both satisfy the electrical and regulatory requirements for green LED indication in surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can SSL-LXA228SUGCTR11 be used as a direct replacement for AM27CGCK03 without circuit modification?

A: Yes. The forward voltage difference (2.1V vs. 2.2V) falls within standard LED circuit design tolerance. No circuit redesign is required for substitution.

Q: What is the significance of the millicandela rating difference (600mcd vs. 200mcd)?

A: The AM27CGCK03 delivers higher luminous intensity. The SSL-LXA228SUGCTR11 provides lower brightness output. Selection depends on application brightness requirements. Both are suitable for standard indication applications.

Q: Are there package compatibility concerns between these two parts?

A: Both components use 2-SMD Gull Wing package configuration with Surface Mount mounting type. Dimensional variations (2.21mm x 2.04mm vs. 2.50mm x 2.00mm) are minor and do not affect standard PCB footprint compatibility. Height difference (2.92mm vs. 3.00mm) is negligible for typical assembly clearance.

Q: Does the viewing angle difference (20° vs. 25°) affect substitution suitability?

A: The SSL-LXA228SUGCTR11 provides a wider viewing angle. This represents an enhancement for applications requiring broader visibility. No compatibility issues result from this parameter difference.

Q: Are both components compliant with current regulatory requirements?

A: Yes. Both AM27CGCK03 and SSL-LXA228SUGCTR11 maintain ROHS3 compliance and REACH unaffected status, confirming alignment with current environmental and regulatory standards.

Q: What is the difference between the Supplier Device Package designations (SMD vs. Axial)?

A: Both components are surface mount devices. The designation difference reflects manufacturer classification methodology and does not affect physical package configuration or PCB assembly compatibility.
