Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLMD481H12L is determined by the following criteria:

Primary Substitution Parameters:

• Cell type: Monocrystalline
• Physical dimensions: 90.00mm × 79.00mm × 2.00mm (±tolerance)
• Manufacturer: ANYSOLAR Ltd
• Series: IXOLAR™
• Voltage - Open Circuit: 7.56 V to 8.29 V range
• Voltage @ Pmpp: 6.06 V to 6.7 V range

Identified Substitutes:

Direct Substitute: SM451K12L — Monocrystalline solar cell with matching physical dimensions, identical open circuit voltage range (8.29 V), and compatible power output (1.176 W). Voltage @ Pmpp of 6.7 V falls within acceptable operating parameters.

Similar Substitute: SM531K12L — Monocrystalline solar cell with matching physical dimensions and voltage characteristics (8.29 V open circuit, 6.7 V @ Pmpp). Higher power output (1.37 W) and current ratings provide enhanced performance within the same form factor.

Parameter Comparison

Engineering Selection Recommendations

SM451K12L Selection: This direct substitute maintains compatibility with existing designs requiring the SLMD481H12L. Both components share identical physical dimensions and comparable electrical characteristics. SM451K12L carries ROHS3 compliance and defined operating temperature range (-40°C ~ 90°C), providing regulatory alignment for new implementations. Product status is obsolete; inventory availability should be verified before design commitment.

SM531K12L Selection: This active-status component offers the highest performance within the compatible form factor, delivering 1.37 W maximum power output compared to the original 1.08 W. Identical physical dimensions and voltage characteristics (8.29 V open circuit, 6.7 V @ Pmpp) ensure mechanical and electrical compatibility. ROHS3 compliance and active product status support long-term supply chain viability. Higher current ratings (205 mA @ Pmpp, 218 mA Isc) represent performance enhancement suitable for applications tolerating increased power delivery.

Frequently Asked Questions (FAQ)

Q: Can SM451K12L and SM531K12L be used interchangeably with SLMD481H12L?

A: Both substitute parts share identical physical dimensions (90.00mm × 79.00mm × 2.00mm) and compatible voltage characteristics. Electrical parameter differences (power output, current ratings) must be evaluated against circuit design requirements. Voltage @ Pmpp values (6.7 V for substitutes vs. 6.06 V for original) represent the primary electrical distinction.

Q: What is the significance of the open circuit voltage difference between SLMD481H12L (7.56 V) and the substitutes (8.29 V)?

A: The 0.73 V increase in open circuit voltage reflects improved cell efficiency in the substitute parts. This parameter determines maximum available voltage under no-load conditions. Circuit designs must accommodate this voltage range; voltage regulation or limiting circuits may require adjustment.

Q: Why is SM531K12L recommended over SM451K12L despite both being substitutes?

A: SM531K12L carries active product status, ensuring ongoing availability and supply chain support. SM451K12L is classified as obsolete, presenting potential long-term sourcing challenges. Both components are electrically compatible; SM531K12L provides superior performance (1.37 W vs. 1.176 W) within identical mechanical constraints.

Q: Are there compliance or certification differences between these parts?

A: SM451K12L and SM531K12L both carry ROHS3 compliance certification. SM531K12L is marked as REACH Affected, while REACH status for SM451K12L is not specified in available data. Both components carry EAR99 ECCN classification. Regulatory requirements for specific applications should be verified against end-use jurisdiction.

Q: What packaging considerations apply to these solar cells?

A: All three components are supplied in bulk packaging. Physical dimensions are standardized at 90.00mm × 79.00mm × 2.00mm, supporting direct mechanical substitution in existing mounting structures. Moisture sensitivity levels differ: SLMD481H12L carries MSL Level 1 (Unlimited), while SM451K12L and SM531K12L are marked as Not Applicable.
