Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLMD321H09L are identified based on the following criteria:

Mandatory Compatibility Parameters:

• Manufacturer: ANYSOLAR Ltd (same manufacturer ensures design consistency)
• Series: IXOLAR™ (same product line)
• Type: Monocrystalline (same cell technology)
• Package / Case: Cells (same form factor classification)
• Physical dimensions: Compatible with 58mm x 58mm footprint or similar rectangular geometry
• Product Status: Active (ensures current availability and supply chain viability)

Electrical Parameter Tolerance: Substitute parts must maintain voltage characteristics within the operational range of the original design. Open-circuit voltage (Voc) and maximum power point voltage (Vmpp) are primary selection criteria. Power output and current ratings may vary within the constraints of the same cell geometry and technology platform.

Parameter Comparison

Engineering Selection Recommendations

SM301K09L is the primary direct substitute for SLMD321H09L. Both parts share identical physical dimensions (58.0mm x 58.0mm x 2.0mm) and maximum power point voltage characteristics (Vmpp 5.02 V vs. 4.5 V). The SM301K09L is active in production status with ROHS3 compliance and defined operating temperature range (-40°C ~ 90°C), providing superior supply chain reliability compared to the obsolete SLMD321H09L. Power output increases from 540 mW to 595 mW with comparable current characteristics at maximum power point (119 mA vs. 120 mA).

SM351K09L is a similar alternative within the IXOLAR™ series, offering higher power output (695 mW) with the same open-circuit voltage (6.22 V) and maximum power point voltage (5.02 V) as SM301K09L. Physical dimensions differ slightly (57.0mm x 64.0mm x 1.8mm), resulting in a rectangular geometry with increased length. This part is also active in production with ROHS3 compliance and defined operating temperature specifications. Selection of SM351K09L is appropriate for applications where increased power output and rectangular cell geometry are compatible with system design constraints.

Both substitute parts are manufactured by ANYSOLAR Ltd within the IXOLAR™ series and utilize monocrystalline technology, ensuring design consistency with the original SLMD321H09L.

Frequently Asked Questions (FAQ)

Q: Can SM301K09L directly replace SLMD321H09L in existing designs?

A: SM301K09L shares identical physical dimensions and compatible voltage characteristics with SLMD321H09L. The primary difference is increased power output (595 mW vs. 540 mW) and active production status. Direct mechanical and electrical compatibility is established based on matching cell dimensions and voltage operating points.

Q: What is the difference between SM301K09L and SM351K09L?

A: Both parts are active IXOLAR™ series monocrystalline cells with identical open-circuit voltage (6.22 V) and maximum power point voltage (5.02 V). SM351K09L provides higher power output (695 mW vs. 595 mW) and operates with a rectangular geometry (57.0mm x 64.0mm) compared to the square geometry of SM301K09L (58.0mm x 58.0mm). Selection depends on available mounting space and power requirements.

Q: Why is SLMD321H09L classified as obsolete?

A: Product obsolescence indicates that ANYSOLAR Ltd has discontinued manufacturing and support for this component. Active alternatives within the same IXOLAR™ series (SM301K09L and SM351K09L) provide equivalent or enhanced functionality with current production status and supply chain availability.

Q: Are the substitute parts RoHS compliant?

A: Both SM301K09L and SM351K09L are ROHS3 compliant, meeting current environmental and material restriction standards. The original SLMD321H09L does not specify RoHS status in available documentation.

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

A: SM301K09L and SM351K09L both specify an operating temperature range of -40°C to 90°C. The original SLMD321H09L does not provide operating temperature specifications. Applications requiring defined thermal performance should reference the substitute part specifications.

Q: Can multiple cells be connected in series or parallel?

A: Cell interconnection design depends on system voltage and current requirements. When connecting substitute cells, maintain consistent cell selection within a single part number to ensure uniform electrical characteristics and performance matching.
