Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AM27SECK03 are identified based on compatibility within the following critical parameters:

Mechanical Compatibility:

• Package type: 2-SMD, Gull Wing configuration
• Mounting type: Surface Mount
• Height maximum: 2.92mm
• Lens style: Round with Domed Top
• Lens transparency: Clear

Electrical Compatibility:

• Forward voltage range: 2.0V to 2.1V
• Test current: 20mA
• Viewing angle: 15° to 20°

Regulatory & Environmental:

• RoHS3 Compliance
• REACH Unaffected status
• MSL rating: 2A to 3

Color & Optical Characteristics: Substitutes operate within the orange to amber spectrum (590nm to 610nm dominant wavelength). Luminous intensity variations are acceptable within the discrete LED indication category, provided the part meets minimum visibility requirements for the application.

The substitute HLMT-QL00-T0011 satisfies all mechanical and electrical compatibility criteria while maintaining regulatory compliance.

Engineering Selection Recommendations

Primary Selection Criteria:

The AM27SECK03 remains the preferred component when the following conditions apply:

• Higher luminous intensity (2700mcd) is required for the application
• Wider viewing angle (20°) is necessary for the intended installation geometry
• Exact wavelength specification at 601nm dominant is critical

Substitute Selection Criteria:

The HLMT-QL00-T0011 is suitable as a substitute when:

• The application tolerates reduced luminous intensity (1000mcd minimum)
• A narrower viewing angle (15°) is acceptable for the installation
• The wavelength shift from 601nm to 590nm (amber vs. orange) does not affect functional requirements
• Supply chain continuity or inventory availability necessitates an alternative source
• Lower moisture sensitivity level (2A vs. 3) aligns with storage and handling procedures

Regulatory Compliance:

Both components maintain ROHS3 compliance and REACH Unaffected status, ensuring compatibility with current environmental and regulatory requirements. Both are in active production status with established supply chains.

Mechanical Compatibility:

Both components share identical package configuration (2-SMD Gull Wing), mounting type (Surface Mount), and maximum height (2.92mm). Dimensional variations in length (0.22mm) and lens diameter (0.13mm) are within typical PCB layout tolerances for surface mount assembly.

Frequently Asked Questions (FAQ)

Q: Can HLMT-QL00-T0011 be used as a direct replacement for AM27SECK03 in all applications?

A: No. The substitute has lower luminous intensity (1000mcd vs. 2700mcd) and a narrower viewing angle (15° vs. 20°). Verify that your application tolerates these reductions before substitution. The wavelength shift from orange (601nm) to amber (590nm) may also affect visual appearance.

Q: What are the key differences between these two parts?

A: The primary differences are luminous intensity, viewing angle, and dominant wavelength. The AM27SECK03 provides higher brightness and wider visibility. The HLMT-QL00-T0011 has lower moisture sensitivity (2A vs. 3), requiring less stringent storage conditions. Both share identical package, mounting type, and height specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both AM27SECK03 and HLMT-QL00-T0011 are ROHS3 Compliant and REACH Unaffected, meeting current environmental regulations.

Q: Will the dimensional differences affect PCB layout?

A: The length difference (0.22mm) and lens diameter difference (0.13mm) are minor and typically within standard PCB layout tolerances for surface mount components. However, verify footprint compatibility with your specific PCB design before assembly.

Q: What is the moisture sensitivity difference, and does it matter?

A: The AM27SECK03 has MSL 3 (168 hours), while HLMT-QL00-T0011 has MSL 2A (4 weeks). Lower MSL ratings require less stringent moisture control during storage and handling. If your manufacturing process includes extended storage periods, the substitute's lower MSL may reduce baking requirements.

Q: Can I use HLMT-QL00-T0011 if my circuit requires exactly 2700mcd brightness?

A: No. The substitute provides only 1000mcd, which is insufficient for applications with strict brightness requirements. Use the AM27SECK03 for high-brightness indication applications.

Q: Are there any electrical parameter differences I should consider?

A: Forward voltage differs by 0.1V (2.1V vs. 2.0V), which is negligible for most applications. Test current is identical at 20mA. Both operate within standard LED circuit design parameters.
