SLMD121H06L Monocrystalline Solar Cell Equivalent & Substitute Parts

Part Overview

The SLMD121H06L is a monocrystalline solar cell manufactured by ANYSOLAR Ltd as part of the IXOLAR™ series. This component delivers 136 mW at 4 V output and is designed for low-power photovoltaic applications. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. Substitute parts must maintain compatibility across electrical performance parameters and physical dimensions to ensure proper integration into existing or new applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLMD121H06L are identified based on the following criteria:

Electrical Compatibility Parameters:

• Monocrystalline cell type (consistent material composition)
• Open circuit voltage within the 4 V nominal range
• Maximum power output in the range of 136–184 mW
• Current characteristics (Pmpp and Isc) proportional to power scaling

Physical Compatibility Parameters:

• Package type: Cells (bare cell format)
• Thickness: 0.09" (2.3mm) or equivalent
• Length and width dimensions compatible with standard mounting configurations

Operational Parameters:

• Operating temperature range support for industrial applications
• Moisture sensitivity classification suitable for the application environment

The SLMD121H06L has two identified substitutes within the IXOLAR™ series: SM111K06L (direct substitute with 147 mW output) and SM141K06L (similar substitute with 184 mW output). Both maintain monocrystalline construction, compatible voltage characteristics, and equivalent physical form factors.

Parameter Comparison

Engineering Selection Recommendations

SM111K06L Selection Criteria: SM111K06L is classified as a direct substitute for SLMD121H06L. This part maintains the closest electrical and physical alignment with the original component. The 147 mW power output represents an 8% increase over the SLMD121H06L, with proportional current scaling. Open circuit voltage increases from 4 V to 4.15 V. Physical dimensions show minimal variation (42.0mm vs 41.0mm length). SM111K06L is active in production status with ROHS3 compliance and defined operating temperature range (-40°C ~ 90°C), providing superior long-term availability and regulatory compliance compared to the obsolete original part.

SM141K06L Selection Criteria: SM141K06L is classified as a similar substitute for SLMD121H06L. This part delivers 184 mW maximum power, representing a 35% increase in power output. Current characteristics scale proportionally (55.1 mA @ Pmpp, 58.6 mA Isc). Physical dimensions increase in both length (42.00mm) and width (23.00mm), with slight thickness reduction (2.10mm). SM141K06L is active in production with ROHS3 compliance and REACH Affected status. Selection of SM141K06L requires verification that the larger physical footprint (0.906" width vs 0.83" width) accommodates existing mounting configurations and that the higher power output aligns with system design parameters.

Compliance and Availability: Both substitute parts are active production components with ROHS3 compliance, ensuring regulatory alignment for new designs and long-term supply chain stability. The SLMD121H06L obsolete status necessitates transition to either substitute for ongoing applications.

Frequently Asked Questions (FAQ)

Q: Can SM111K06L directly replace SLMD121H06L without circuit modifications?

A: SM111K06L is electrically compatible as a direct substitute. The 8% power increase and 0.15 V open circuit voltage increase are within typical system tolerance ranges for monocrystalline solar cell applications. Physical dimensions vary by 1.0mm in length and maintain identical width and thickness, compatible with standard cell mounting. No circuit modifications are required for basic substitution.

Q: What are the key differences between SM111K06L and SM141K06L?

A: SM111K06L delivers 147 mW with 4.15 V open circuit voltage and maintains the original cell width (0.83"). SM141K06L delivers 184 mW with identical 4.15 V open circuit voltage but increases width to 0.906". The 35% power increase in SM141K06L results from larger cell dimensions. Selection depends on available mounting space and system power requirements.

Q: Is SM141K06L suitable for applications requiring the original SLMD121H06L power output?

A: SM141K06L provides higher power output (184 mW vs 136 mW) and larger physical dimensions. This part is suitable only when the application can accommodate increased power generation and the larger cell footprint (0.906" width vs 0.83" width). For applications requiring output matching the original specification, SM111K06L is the appropriate selection.

Q: What is the impact of the 0.15 V open circuit voltage increase in substitute parts?

A: Both substitute parts operate at 4.15 V open circuit voltage compared to the original 4 V specification. This 3.75% increase is typical within monocrystalline solar cell manufacturing tolerances and does not require circuit redesign for standard photovoltaic applications. System voltage regulation circuits accommodate this variation.

Q: Are there packaging differences between the substitute parts?

A: SM111K06L is supplied in Bulk packaging, while SM141K06L is supplied in Tray packaging. Both maintain the Cells package type (bare cell format). Packaging selection affects handling, storage, and integration processes but does not impact electrical or mechanical compatibility.

Q: What operating temperature range should be considered for substitute selection?

A: Both SM111K06L and SM141K06L specify -40°C ~ 90°C operating temperature range, providing defined thermal performance across industrial and commercial temperature environments. The original SLMD121H06L does not specify operating temperature range. Substitute parts offer superior thermal specification documentation for system design validation.
