SML-LX2835GYC-TR Equivalent & Substitute Parts

Part Overview

The SML-LX2835GYC-TR is an active, surface-mount LED indicator manufactured by Lumex Opto/Components Inc. This dual-color device combines green and yellow LED elements in a single 2835 SMD package with J-Lead configuration. The component operates at 2V forward voltage for both colors with 20mA test current, providing 15mcd green and 25mcd yellow luminous intensity through a clear, rectangular lens with 120° viewing angle.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications are maintained across alternative package styles and manufacturers. The primary substitute listed maintains functional equivalence while offering different physical dimensions and packaging format.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SML-LX2835GYC-TR is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Dual green and yellow color configuration with independent operation
• Forward voltage within acceptable tolerance of 2V nominal for both colors
• Test current specification of 20mA for both colors
• Wavelength performance in the green (565–570nm) and yellow (583–585nm) ranges
• 120° viewing angle maintained

Mechanical Compatibility Criteria:

• Surface-mount technology requirement
• Four-lead configuration for dual-color independent operation
• Clear lens transparency
• Overall dimensions compatible with standard PCB footprints

Compliance Criteria:

• ROHS3 compliance
• REACH unaffected status
• EAR99 export classification

The substitute HSMF-A206-A00J1 meets these criteria through equivalent electrical performance and compliance certifications, despite differences in package style (4-PLCC versus 4-SMD J-Lead) and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

SML-LX2835GYC-TR Selection Criteria:

• Primary choice when rectangular lens geometry and 1.80mm maximum height are required
• Preferred for applications with strict vertical clearance constraints
• Optimal for designs requiring 15mcd green and 25mcd yellow luminous intensity balance
• Suitable for standard MSL 3 storage and handling conditions

HSMF-A206-A00J1 Selection Criteria:

• Alternative when round lens appearance is acceptable or preferred
• Applicable when forward voltage tolerance of 2.2V is compatible with circuit design
• Suitable for applications where 20mcd green and 16mcd yellow intensity distribution is acceptable
• Recommended when MSL 2A moisture sensitivity level provides operational advantage
• Compatible with standard 4-PLCC footprint designs

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance across equivalent applications. Selection between these parts depends on PCB layout constraints, lens geometry requirements, and luminous intensity specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can HSMF-A206-A00J1 directly replace SML-LX2835GYC-TR on existing PCBs?

A: Direct PCB replacement is not possible without footprint modification. The SML-LX2835GYC-TR uses 4-SMD J-Lead package while HSMF-A206-A00J1 uses 4-PLCC package. Both are surface-mount configurations, but lead patterns and solder pad layouts differ. PCB redesign is required for physical substitution.

Q: What are the electrical differences between these parts?

A: Forward voltage differs by 0.2V for both colors (2V versus 2.2V). Millicandela ratings vary: SML-LX2835GYC-TR provides 15mcd green and 25mcd yellow, while HSMF-A206-A00J1 provides 20mcd green and 16mcd yellow. Peak wavelengths differ slightly within acceptable green (565–570nm) and yellow (583–585nm) ranges. Test current remains constant at 20mA for both colors.

Q: Are both parts suitable for the same circuit designs?

A: Electrical substitution requires circuit analysis. The 0.2V forward voltage difference affects current-limiting resistor calculations. Designs using fixed resistor values must be re-evaluated. Luminous intensity differences may impact visual indication requirements. Both parts maintain 120° viewing angle and clear lens transparency.

Q: What is the significance of MSL rating differences?

A: SML-LX2835GYC-TR has MSL 3 (168 hours), while HSMF-A206-A00J1 has MSL 2A (4 weeks). MSL 2A indicates lower moisture sensitivity and longer shelf life under standard conditions. This affects storage, handling, and reflow processing requirements. MSL 3 components require more controlled storage environments.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SML-LX2835GYC-TR and HSMF-A206-A00J1 are ROHS3 compliant and REACH unaffected. Both carry EAR99 export classification and share the same HTSUS code (8541.41.0000). Regulatory compliance is equivalent across both parts.

Q: What physical dimension differences exist?

A: Length is identical at 3.20mm. Width differs by 0.10mm (2.70mm versus 2.80mm). Height differs by 0.30mm (1.80mm versus 2.10mm). Lens style differs: SML-LX2835GYC-TR has rectangular lens with flat top; HSMF-A206-A00J1 has round lens with flat top. These differences affect PCB layout and clearance planning.
