AM27MGC03 Equivalent & Substitute Parts Reference

Part Overview

The AM27MGC03 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 2.1V forward voltage with a dominant wavelength of 570nm and peak wavelength of 574nm. The component features a clear, domed round lens with 1.78mm diameter and 800mcd brightness rating, suitable for standard LED indication circuits requiring 20mA test current.

Substitute parts are identified to address inventory availability, extended lead times, or specific packaging requirements while maintaining functional compatibility within the defined electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM27MGC03 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Color: Green
• Wavelength - Peak: 574nm (within green spectrum)
• Package / Case: 2-SMD, Gull Wing
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variations:

• Voltage - Forward (Vf): ±0.1V tolerance acceptable (2.1V ±0.1V = 2.0V to 2.2V range)
• Current - Test: 20mA standard
• Millicandela Rating: Substitutes may vary; brightness differences do not prevent functional substitution in indication circuits
• Lens Size: Minor variations acceptable (1.78mm to 1.90mm diameter range)
• Viewing Angle: Variations acceptable based on application requirements (20° to 25° range)
• Height: Variations acceptable within PCB clearance limits (2.92mm to 3.00mm range)

The substitute part SSL-LXA228SUGCTR11 meets all mandatory criteria and falls within allowable parameter variations.

Engineering Selection Recommendations

AM27MGC03 (Kingbright) - Primary Selection

Use the AM27MGC03 when:

• Original design specification requires 800mcd brightness
• Bulk packaging format is acceptable for assembly operations
• Kingbright component availability meets project timeline
• Moisture Sensitivity Level 3 (168 Hours) is compatible with storage and handling procedures

SSL-LXA228SUGCTR11 (Lumex Opto/Components Inc.) - Substitute Selection

Use SSL-LXA228SUGCTR11 when:

• AM27MGC03 is unavailable or subject to extended lead times
• Application circuit design accommodates 200mcd brightness output
• Tape & Reel packaging format is required for automated assembly
• Moisture Sensitivity Level 4 (72 Hours) storage requirements can be met
• Forward voltage tolerance of 2.2V (versus 2.1V) is acceptable within circuit design margins

Both components are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can SSL-LXA228SUGCTR11 directly replace AM27MGC03 in existing designs?

A: Yes, SSL-LXA228SUGCTR11 is electrically and mechanically compatible. The forward voltage difference of 0.1V (2.2V vs 2.1V) falls within standard circuit tolerance. The primary design consideration is brightness: SSL-LXA228SUGCTR11 provides 200mcd versus 800mcd. Verify that the application circuit does not require the higher brightness specification.

Q: What is the impact of the 800mcd to 200mcd brightness difference?

A: The AM27MGC03 provides four times the brightness output. In indication circuits where visual brightness is critical for visibility under ambient lighting conditions, this difference is significant. In low-light or controlled environments, the 200mcd output of SSL-LXA228SUGCTR11 may be sufficient. Circuit design review is necessary to confirm acceptability.

Q: Are the packaging formats interchangeable?

A: No. AM27MGC03 is supplied in bulk packaging, while SSL-LXA228SUGCTR11 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated pick-and-place assembly. Bulk packaging requires manual handling. Confirm your assembly process compatibility before selection.

Q: What is the significance of Moisture Sensitivity Level differences?

A: AM27MGC03 has MSL 3 (168 Hours), while SSL-LXA228SUGCTR11 has MSL 4 (72 Hours). MSL 4 requires more stringent moisture control during storage and handling. If components are stored in standard conditions without desiccant control, MSL 3 is more forgiving. Verify your storage and handling procedures meet MSL 4 requirements before selecting SSL-LXA228SUGCTR11.

Q: Are both components suitable for high-volume production?

A: Yes. Both components are Active status products with ROHS3 compliance and established supply chains. AM27MGC03 has 862 Pcs in stock; SSL-LXA228SUGCTR11 has 31,762 Pcs in stock. SSL-LXA228SUGCTR11 offers significantly higher inventory availability for large-volume requirements.

Q: What is the viewing angle difference between these components?

A: AM27MGC03 has a 20° viewing angle; SSL-LXA228SUGCTR11 has a 25° viewing angle. The wider 25° angle provides visibility across a broader range of observation positions. This difference is generally not critical in standard indication applications but may be relevant in specific mounting orientations.
