Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMP2-YC is determined by the following critical parameters:

Parametric Equivalents maintain identical or near-identical electrical and mechanical specifications:

• Forward voltage (Vf): 2V
• Test current: 20mA
• Wavelength range: 585nm to 591nm (yellow spectrum)
• Viewing angle: 120°
• Mounting type: Surface Mount
• Package compatibility: 2-PLCC or 2-SMD, J-Lead
• Physical dimensions: Within 3.10-3.20mm length, 2.70-2.80mm width
• Height: 2.00-2.10mm maximum

Similar Substitutes share core electrical characteristics but differ in brightness rating or wavelength:

• Forward voltage: 2V
• Test current: 10-20mA
• Wavelength: 589-605nm (yellow to orange spectrum)
• Viewing angle: 120°
• Mounting type: Surface Mount
• Package type: 2-SMD, J-Lead or 2-PLCC

Substitution logic prioritizes active product status, RoHS compliance where available, and dimensional compatibility with existing PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SMTL2-YC

The SMTL2-YC is the direct parametric equivalent to the SMP2-YC. Both components are manufactured by Bivar Inc., share identical electrical specifications (2V forward voltage, 20mA test current, 16mcd brightness), and maintain the same 585nm dominant wavelength. The SMTL2-YC is currently in active production status with ROHS3 compliance certification. Physical dimensions are identical (3.20mm L x 2.80mm W), with maximum height of 2.10mm compared to the original 2.00mm. This component is suitable for direct substitution in existing PCB layouts without design modification. Packaging is supplied in Tape & Reel format with 1081 units in current inventory.

Secondary Recommendations: Everlight Electronics Components

The 67-21/Y2C-AS1T1/2T and 67-21UYC/S530-A6/TR8 are active yellow LED alternatives from Everlight Electronics Co Ltd. Both maintain 2V forward voltage and 120° viewing angle compatibility. The 67-21/Y2C-AS1T1/2T offers higher brightness at 270mcd with 590nm wavelength, suitable for applications requiring increased luminous intensity. The 67-21UYC/S530-A6/TR8 provides intermediate brightness at 117mcd with 589nm wavelength. Both use 2-SMD, J-Lead package configuration with 2.10mm maximum height. Physical dimensions are comparable to the original part. These components require PCB layout verification due to package type transition from 2-PLCC to 2-SMD, J-Lead.

Tertiary Recommendation: VLMF3100-GS18

The VLMF3100-GS18 from Vishay Semiconductor Opto Division is an orange LED (605nm) with 2V forward voltage and 120° viewing angle. This component operates at reduced test current (10mA versus 20mA) and provides 90mcd brightness. The VLMF3100-GS18 features superior moisture sensitivity rating (MSL 2A versus MSL 4) and ROHS3 compliance. Physical dimensions are 3.00mm L x 2.80mm W with 1.85mm maximum height, providing the most compact profile. This component is suitable only for applications where orange wavelength substitution is acceptable and where reduced current draw is beneficial. Package type is 2-SMD, J-Lead, requiring PCB layout verification.

All substitute components share the following compliance attributes with the original part:

• ECCN: EAR99
• HTSUS: 8541.41.0000
• Surface mount assembly compatibility
• 120° viewing angle specification

Frequently Asked Questions (FAQ)

Q: Can SMTL2-YC be used as a direct replacement for SMP2-YC without PCB modification?

A: Yes. The SMTL2-YC maintains identical electrical specifications and physical dimensions with the SMP2-YC. The maximum height difference is 0.10mm (2.10mm versus 2.00mm), which is within standard PCB assembly tolerances. No design modification is required.

Q: What is the difference between 2-PLCC and 2-SMD, J-Lead packages?

A: The 2-PLCC (Plastic Leaded Chip Carrier) and 2-SMD, J-Lead are distinct surface mount package types with different lead configurations and footprints. Transition between these package types requires PCB layout modification, including changes to solder pad geometry and spacing. Verify PCB design files before implementing Everlight or Vishay alternatives.

Q: Why does the VLMF3100-GS18 have a different color (orange) than the original yellow LED?

A: The VLMF3100-GS18 operates at 605nm wavelength (orange spectrum) compared to the SMP2-YC at 585nm (yellow spectrum). This component is listed as a similar substitute based on shared electrical parameters (2V forward voltage, 120° viewing angle, surface mount compatibility) but is suitable only for applications where color substitution is acceptable. Verify application requirements before selection.

Q: What does MSL (Moisture Sensitivity Level) mean for component selection?

A: MSL indicates the maximum time a component can be exposed to ambient moisture before soldering. MSL 4 (72 Hours) allows 72 hours of exposure, while MSL 2A (4 Weeks) allows 4 weeks. The VLMF3100-GS18 has superior moisture tolerance. For standard manufacturing environments, both ratings are acceptable. Extended storage or humid environments may favor the VLMF3100-GS18.

Q: Are all substitute parts RoHS compliant?

A: The SMTL2-YC and VLMF3100-GS18 are certified ROHS3 compliant. The Everlight components (67-21/Y2C-AS1T1/2T and 67-21UYC/S530-A6/TR8) do not have specified RoHS status in the provided data. Verify RoHS compliance requirements with your procurement or quality department before final component selection.

Q: What is the brightness difference between substitute options?

A: The SMP2-YC and SMTL2-YC both provide 16mcd brightness. The 67-21/Y2C-AS1T1/2T provides 270mcd (significantly brighter), the 67-21UYC/S530-A6/TR8 provides 117mcd (moderately brighter), and the VLMF3100-GS18 provides 90mcd (moderately brighter). Brightness selection depends on application visibility requirements. Higher brightness components may require circuit current limiting adjustment.

Q: Can I use a 10mA rated component (VLMF3100-GS18) in a circuit designed for 20mA (SMP2-YC)?

A: The VLMF3100-GS18 is rated for 10mA test current, while the SMP2-YC operates at 20mA. Direct substitution in a 20mA circuit may result in reduced brightness or component stress. Circuit redesign is required to reduce operating current to 10mA if using the VLMF3100-GS18. Consult component datasheets for absolute maximum ratings before implementation.

Q: What inventory levels are available for each substitute?

A: Current inventory levels are: SMP2-YC (894 units), SMTL2-YC (1081 units), 67-21/Y2C-AS1T1/2T (1156 units), 67-21UYC/S530-A6/TR8 (817 units), and VLMF3100-GS18 (1120 units). Inventory levels are subject to change. Verify current availability with your supplier before finalizing procurement decisions.
