Key Parameters

Substitute Part Grouping Explanation

Substitution of the SM351K09TL is determined by electrical and mechanical parameter equivalence within the IXOLAR™ monocrystalline solar cell product line. The critical parameters governing substitution are:

Electrical Parameters:

• Maximum power output (695 mW nominal)
• Open circuit voltage (6.22 V)
• Current at maximum power point (138 mA)
• Voltage at maximum power point (5.02 V)
• Short circuit current (147 mA)

Mechanical Parameters:

• Physical dimensions (57.00 mm × 64.00 mm × 1.50 mm)
• Package type (Cells)
• Monocrystalline cell construction

Environmental & Compliance Parameters:

• Operating temperature range (-40°C to 90°C)
• RoHS compliance
• Moisture sensitivity level (MSL 1)

The SM351K09TF qualifies as a direct substitute based on matching electrical performance within standard manufacturing tolerances, identical physical dimensions, and equivalent environmental specifications. The transition from obsolete to active product status ensures continued component availability.

Parameter Comparison

Engineering Selection Recommendations

The SM351K09TF is the direct equivalent substitute for the obsolete SM351K09TL. Selection of the SM351K09TF is based on the following engineering criteria:

Electrical Equivalence: The SM351K09TF maintains maximum power output within 0.06% of the original specification (694.6 mW versus 695 mW), with current parameters varying by less than 0.22%. These variations fall within standard manufacturing tolerances for monocrystalline solar cell production and do not affect system-level performance in series or parallel array configurations.

Mechanical Compatibility: Both parts share identical physical dimensions (57.00 mm × 64.00 mm × 1.50 mm) and package type, ensuring direct mechanical interchangeability in existing mounting and interconnection designs.

Compliance & Availability: The SM351K09TF carries active product status with confirmed inventory availability (1091 pieces in stock), whereas the SM351K09TL is obsolete. Both components maintain RoHS compliance and MSL 1 rating. The SM351K09TF includes additional certifications (REACH Unaffected, ECCN EAR99, HTSUS 8541.42.0010) that support regulatory and supply chain requirements.

Thermal Performance: Identical operating temperature range (-40°C to 90°C) ensures equivalent thermal behavior across all application environments.

Frequently Asked Questions (FAQ)

Q: Can the SM351K09TF directly replace the SM351K09TL in existing designs?

A: Yes. The SM351K09TF is electrically and mechanically equivalent to the SM351K09TL. Electrical parameters vary by less than 0.22%, physical dimensions are identical, and both components operate across the same temperature range. Direct substitution is supported without design modification.

Q: What is the significance of the product status change from Obsolete to Active?

A: The SM351K09TL is classified as obsolete, indicating discontinued production and limited availability. The SM351K09TF maintains active product status with confirmed inventory, ensuring reliable supply for new designs and replacement applications. This transition is the primary driver for substitution.

Q: Are there packaging differences between these parts?

A: The SM351K09TL is listed with packaging designation "-" (unspecified), while the SM351K09TF specifies "Bulk" packaging. Both components use the same "Cells" package type with identical physical dimensions. Packaging designation refers to order quantity and delivery format, not component construction.

Q: How do the electrical performance variations affect system design?

A: The SM351K09TF exhibits maximum power output of 694.6 mW compared to 695 mW for the SM351K09TL, representing a 0.06% difference. Current parameters vary by 0.20% to 0.22%. These variations are within standard manufacturing tolerances for monocrystalline solar cells and do not require system recalculation or performance adjustment.

Q: What compliance certifications apply to the substitute part?

A: The SM351K09TF is RoHS Compliant, REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8541.42.0010. Both the main part and substitute maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Are these parts suitable for series and parallel array configurations?

A: Yes. Both the SM351K09TL and SM351K09TF are monocrystalline solar cells with identical voltage and current characteristics, supporting standard series and parallel interconnection schemes. The electrical equivalence ensures consistent array performance.
