Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLMD481H08L is determined by the following criteria:

• Cell Type: Monocrystalline construction matching the original specification
• Voltage Compatibility: Open circuit voltage and maximum power point voltage within acceptable operating ranges for series and parallel array configurations
• Current Characteristics: Short circuit current and maximum power point current suitable for existing circuit designs
• Physical Dimensions: Cell dimensions permitting mechanical fit within existing mounting structures
• Compliance Standards: RoHS3 compliance and equivalent regulatory certifications
• Manufacturer Consistency: ANYSOLAR Ltd IXOLAR™ series components ensuring design continuity

The two substitute parts identified—SM451K08L and SM531K08L—meet these criteria while offering active product status and enhanced operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

SM451K08L serves as the primary substitute for SLMD481H08L. This part maintains identical physical dimensions (89.0mm x 55.0mm x 2.0mm), ensuring direct mechanical compatibility. The SM451K08L delivers 784 mW output with 5.53 V open circuit voltage, representing a 9.8% power increase over the original specification. Current characteristics remain closely aligned, with Isc of 187 mA compared to the original 200 mA. The part holds active product status with defined operating temperature range (-40°C ~ 90°C) and maintains ROHS3 compliance.

SM531K08L provides an alternative substitute with higher power output (913 mW) and increased current capacity (Isc 218 mA). This part features a reduced thickness (1.80mm versus 2.00mm) and slightly narrower width (52.00mm versus 55.00mm). The SM531K08L is suitable for applications where increased power generation is beneficial and mechanical constraints permit the dimensional variation. Both substitute parts are manufactured by ANYSOLAR Ltd within the IXOLAR™ series, ensuring design consistency and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can SM451K08L directly replace SLMD481H08L in existing installations?

A: Yes. The SM451K08L maintains identical physical dimensions and mounting compatibility. The higher voltage output (5.53 V versus 5.04 V) and power rating (784 mW versus 714 mW) are compatible with series and parallel array configurations designed for the original part.

Q: What are the key differences between SM451K08L and SM531K08L?

A: Both parts share identical open circuit voltage (5.53 V) and maximum power point voltage (4.46 V). The SM531K08L delivers higher power output (913 mW versus 784 mW) and higher short circuit current (218 mA versus 187 mA). Physical dimensions differ: SM531K08L is 1.80mm thick and 52.00mm wide, compared to SM451K08L at 2.00mm thick and 55.00mm wide.

Q: Are dimensional variations between substitutes critical for selection?

A: Dimensional compatibility depends on mounting structure design. SM451K08L provides identical dimensions to SLMD481H08L for direct fit. SM531K08L requires verification of mechanical clearance due to reduced thickness and width. Both parts maintain the 89.00mm length dimension.

Q: Do substitute parts meet the same compliance standards?

A: Yes. Both SM451K08L and SM531K08L are ROHS3 compliant and manufactured by ANYSOLAR Ltd. Both parts are classified as active products with specified operating temperature ranges (-40°C ~ 90°C), providing enhanced reliability documentation compared to the obsolete SLMD481H08L.

Q: How do current characteristics affect circuit design?

A: The SM451K08L maintains similar maximum power point current (176 mA versus 178 mA) with slightly reduced short circuit current (187 mA versus 200 mA). The SM531K08L increases both parameters (205 mA and 218 mA respectively). Circuit designs must accommodate these current variations in charge controller and wiring specifications.
