Key Parameters

Substitute Part Grouping Explanation

Substitution for the SLMD121H09L is determined by alignment across the following critical parameters:

Manufacturer Consistency: All substitute parts must originate from ANYSOLAR Ltd to ensure design compatibility and performance predictability within the IXOLAR™ series ecosystem.

Cell Type: Monocrystalline construction is mandatory. This determines the efficiency characteristics, temperature coefficient, and electrical performance profile required for direct substitution.

Electrical Performance Window: Substitute parts must operate within compatible voltage and current ranges. The SLMD121H09L operates at 5.67 V open circuit and 50 mA short circuit current. Substitute cells with higher power output (220 mW or 277 mW) and proportionally increased current ratings remain functionally compatible in series or parallel array configurations.

Operating Temperature Range: The main part lacks specified operating temperature data. Substitute parts rated for -40°C to 90°C provide defined thermal performance boundaries suitable for industrial and commercial deployment.

Product Status and Compliance: Active product status with ROHS3 compliance and REACH Affected designation indicates current manufacturing support and regulatory alignment, addressing the obsolescence of the main part.

Parameter Comparison

Engineering Selection Recommendations

SM111K09L Selection: This part represents the direct active equivalent with minimal performance deviation. Power output increases by 9.5% (220 mW vs. 201 mW), while open circuit voltage rises from 5.67 V to 6.22 V. Short circuit current decreases slightly to 46.7 mA. The part carries active product status, ROHS3 compliance, and defined operating temperature range (-40°C to 90°C), providing regulatory certainty and manufacturing continuity. Suitable for applications where the original SLMD121H09L specifications are primary design constraints.

SM141K09L Selection: This part delivers 277 mW maximum power with identical open circuit voltage (6.22 V) to the SM111K09L. Short circuit current increases to 58.6 mA, reflecting higher power generation capacity. Active product status, ROHS3 compliance, and equivalent operating temperature range ensure regulatory alignment. Selection is appropriate for applications requiring increased power output within the same voltage class, or where higher current capacity supports system-level efficiency improvements.

Both substitute parts maintain monocrystalline construction, IXOLAR™ series alignment, and ANYSOLAR Ltd manufacturing origin. Active product status ensures ongoing availability and supply chain stability compared to the obsolete SLMD121H09L.

Frequently Asked Questions (FAQ)

Q: Can SM111K09L and SM141K09L be used interchangeably with SLMD121H09L?

A: Both parts are functionally compatible as direct substitutes within the same application architecture. SM111K09L provides the closest performance match with 220 mW output. SM141K09L offers higher power generation at 277 mW. Selection depends on system voltage and current requirements. Both maintain monocrystalline construction and IXOLAR™ series compatibility.

Q: What is the primary difference between SM111K09L and SM141K09L?

A: Maximum power output differs: SM111K09L delivers 220 mW while SM141K09L delivers 277 mW. Both share identical open circuit voltage (6.22 V) and operating temperature range (-40°C to 90°C). SM141K09L exhibits higher short circuit current (58.6 mA vs. 46.7 mA), reflecting increased power generation capacity. Physical dimensions also differ slightly.

Q: Why is SLMD121H09L listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. SM111K09L and SM141K09L represent current-generation alternatives from the same manufacturer and series, ensuring design continuity with improved availability and regulatory compliance.

Q: Are there compliance differences between the main part and substitutes?

A: Yes. SLMD121H09L carries REACH Unaffected status with unspecified RoHS compliance. Both SM111K09L and SM141K09L are ROHS3 Compliant and REACH Affected, indicating alignment with current environmental and hazardous substance regulations. This provides regulatory certainty for new designs and ongoing system support.

Q: How do voltage specifications compare across these parts?

A: SLMD121H09L operates at 5.67 V open circuit and 4.5 V at maximum power point. Both SM111K09L and SM141K09L operate at 6.22 V open circuit and 5.02 V at maximum power point. The 0.55 V increase in open circuit voltage reflects improved cell efficiency in the substitute parts. Series and parallel array configurations must account for these voltage differences.

Q: What packaging options are available for substitute parts?

A: SM111K09L is supplied in Bulk packaging. SM141K09L is supplied in Tray packaging. Both differ from the main part's Cell (9) package designation. Packaging selection should align with assembly process requirements and inventory management protocols.
