Key Parameters

Substitute Part Grouping Explanation

Substitution of the SLMD121H08L is determined by the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Cell type: Monocrystalline construction
• Voltage class: Open circuit voltage range compatible with system design
• Power output: Maximum power rating within acceptable tolerance for the application
• Current characteristics: Short circuit current and maximum power point current
• Physical dimensions: Length, width, and height must accommodate mechanical constraints
• Manufacturer: ANYSOLAR Ltd IXOLAR™ series maintains consistent quality and performance standards

Substitute Parts Identified:

1. SM111K08L (Direct Substitute) – Active status, higher power output (196 mW), compatible voltage class (5.53 V Voc), similar current characteristics, comparable dimensions (87.0mm x 14.0mm x 2.0mm)

2. SM141K08L (Similar Substitute) – Active status, significantly higher power output (246 mW), compatible voltage class (5.53 V Voc), higher current ratings, slightly larger dimensions (88.00mm x 15.00mm x 2.10mm)

Parameter Comparison

Engineering Selection Recommendations

SM111K08L Selection Criteria:

• Active product status ensures ongoing availability and supply chain stability
• ROHS3 compliance and REACH affected status indicate current regulatory alignment
• Power output increase of 18 mW (10.1% above SLMD121H08L) with minimal dimensional change
• Current @ Pmpp remains within 1.6% of original specification
• Dimensions nearly identical (87.0mm vs 86.00mm length; 14.0mm vs 14.00mm width)
• Suitable for direct replacement in space-constrained applications

SM141K08L Selection Criteria:

• Active product status with full regulatory compliance (ROHS3)
• Power output increase of 68 mW (38.2% above SLMD121H08L) for higher energy conversion requirements
• Voltage characteristics identical to SM111K08L (5.53 V Voc, 4.46 V @ Pmpp)
• Slightly larger dimensions (88.00mm x 15.00mm x 2.10mm) require mechanical accommodation
• Higher current ratings (55.1 mA @ Pmpp, 58.6 mA Isc) necessitate circuit design review
• Appropriate for applications where increased power output justifies dimensional tolerance

Frequently Asked Questions (FAQ)

Q: Can SM111K08L directly replace SLMD121H08L without circuit modification?

A: SM111K08L is dimensionally compatible (87.0mm x 14.0mm x 2.0mm vs 86.00mm x 14.00mm x 2.00mm) and maintains similar current characteristics (43.9 mA @ Pmpp vs 44.6 mA). The voltage increase from 5.04 V to 5.53 V open circuit requires circuit evaluation to confirm system tolerance. No other modifications are necessary.

Q: What are the mechanical constraints when considering SM141K08L?

A: SM141K08L dimensions are 88.00mm x 15.00mm x 2.10mm compared to SLMD121H08L at 86.00mm x 14.00mm x 2.00mm. Length increases by 2.00mm, width by 1.00mm, and thickness by 0.10mm. Mechanical mounting and enclosure design must accommodate these differences.

Q: How do electrical characteristics differ between the three parts?

A: SLMD121H08L operates at 178 mW maximum power. SM111K08L increases output to 196 mW with higher open circuit voltage (5.53 V vs 5.04 V). SM141K08L delivers 246 mW with identical voltage characteristics to SM111K08L but significantly higher current ratings (55.1 mA @ Pmpp, 58.6 mA Isc). Circuit design must accommodate these power and current variations.

Q: What is the regulatory status difference between the main part and substitutes?

A: SLMD121H08L carries REACH Unaffected status. Both SM111K08L and SM141K08L are REACH Affected and ROHS3 Compliant, indicating compliance with current environmental and hazardous substance regulations. This represents an improvement in regulatory alignment for new designs.

Q: Are all three parts from the same manufacturer and series?

A: All three parts are manufactured by ANYSOLAR Ltd within the IXOLAR™ series. This ensures consistent design philosophy, quality standards, and performance reliability across the product family.

Q: Which substitute should be selected for a direct replacement scenario?

A: SM111K08L is the appropriate choice for direct replacement due to minimal dimensional variation, comparable current characteristics, and active product status. SM141K08L is suitable only when increased power output (246 mW vs 178 mW) is required and mechanical space permits the larger dimensions.
